Ronchi, L., Ryzhikov, A., Nouali, H., Daou, T.J., Albrecht, S. and Patarin, J. Extra large pore opening CFI and DON-type zeosils for mechanical energy storage 2018 Microporous Mesoporous Mater.
Vol. 255(Supplement C), pp. 211-219 
article URL 
Abstract: Abstract The energetic performances of pure silica CFI and DON-type zeolites (zeosils) were studied by intrusion-extrusion experiments in water and LiCl aqueous solutions at different concentrations. For both zeosils, characterized by a 1D channel system with 14 MR pore openings, when water is used as nonwetting liquid a perfect reversible spring behavior is observed with an intrusion pressure of 75 and 26 MPa, respectively. The lower value for the DON-type structure is probably due to a larger pore aperture. The intrusion pressures in both cases rise considerably with the LiCl concentration, but the doubling of the salt concentration from 10 to 20 M leads only to a slight increase of the intrusion pressure. The maximal stored energy achieves 14.6 and 6.8 J/g for CFI and DON-type zeosil-based systems, respectively. The zeolite samples were characterized before and after intrusion-extrusion experiments by XRD, SEM, N2 adsorption-desorption, TG and NMR analysis in order to get a better understanding of the influence of these intrusion-extrusion experiments on the CFI and DON-type structures.

Abstract: Abstract Designing sustainable and industrially viable processing methods to synthesize ordered mesoporous films is a necessary condition to tap their full potential of applications. In order to respond to this challenge, well-established photoacid-catalyzed sol-gel photopolymerization has been harnessed to prepare large (>100 cm2) and micrometer-thick porous silica films possessing a 2D hexagonal mesostructure. Our UV irradiation system consists of two inexpensive and low radiant power fluorescent UV tubes (3 mW cm−2, 280-380 nm) enclosed in a hygrometric chamber. Precise conditions to promote copolymer/silica hybrid film mesostructuration have been determined as regards relative humidity, film thickness and templating agent concentration. The mesostructured films have been analyzed using an extensive range of techniques including electron microscopy, grazing-incidence small-angle X-ray scattering (GISAXS), and N2 sorption measurements, and solid-state NMR spectroscopy. Mesoporous silica films with a specific surface area up to 314 m2 g−1 have been achieved with a very low level of microporosity. Coupling of X-ray diffraction (XRD) and FTIR spectroscopy has enabled to shed light into the photoinduced self-assembly mechanism.

Vol. 98, pp. 50-60 
article DOI URL 
Abstract: Zeolite structure determination and zeolite framework generation are not new problems but due to the increasing computer power, these problems came back and they are still a challenge despite the recent progress in terms of structural resolution from X-rays and electron diffraction. The infinite number of potential solutions and the computational cost of this problem make the use of metaheuristics significant for this problem. In this paper, we propose a new approach based on parallel genetic hybrid algorithm for zeolites using a modified modelization of the objective function to find hypothetical zeolite structures, close to the thermodynamic feasibility criterion. A population made of random atoms is initialized. At each generation, a crossover operator and a mutation heuristic are applied. Each individual of the population generates a potential zeolitic structure by applying the symmetry operators of a given crystallographic space group. This structure is evaluated with our objective function. From the unit cell parameters and the number of T atoms in the asymmetric unit, 6 possible zeolitic interesting structures have been found. © 2016 Elsevier Ltd

Abidi, N., Duplay, J., Jada, A., Baltenweck, R., Errais, E., Semhi, K. and Trabelsi-Ayadi, M. Toward the understanding of the treatment of textile industries' effluents by clay: adsorption of anionic dye on kaolinite 2017 Arabian Journal of Geosciences
Vol. 10(16), pp. UNSP 373 
article DOI  
Abstract: Clays, particularly kaolinite, are promising adsorbents for the treatment of textile effluents, but there is a need of better understanding the mechanisms of adsorption, especially in the case of anionic dyes. Thus, the removal of RR120 anionic dye was investigated using Tunisian raw clay (TBK) composed of kaolinite and illite, and a standard kaolinite (KGa-2), and conducting batch experiments by varying different parameters (contact time, ionic strength, concentration, temperature). We investigated the clays' surface charges by electrophoretic mobility measures and the dye-clay interactions during adsorption, by the streaming-induced potentials (SIP). The results showed that KGa-2 has higher adsorption capacity for RR120 dye than TBK clay, moreover enhanced by increasing the ionic strength and/or lowering the pH of the aqueous. The SIP results showed an increase of negative charges for both clays, reflecting the adsorption of the anionic dye on the positive charges of the amphoteric surfaces of the clays. The SIP magnitudes indicated a higher adsorption rate for KGa-2 in accordance with the kinetic study. The Sips model that described the best adsorption isotherms indicates lateral interactions of the dye molecules, stronger in the case of KGa-2 than TBK. Also, the dye molecules form a thinner layer on KGa-2 surfaces. In addition, the dye molecule's structure was not altered, as verified by mass spectrometry. The adsorption process was feasible and spontaneous and favored at ambient temperature. Thus, kaolinite-rich clays are effective in the removal of anionic dyes in aqueous solution and potential good adsorbents in wastewater treatment.

Adohi, B., Brosseau, C., Laur, V. and Haidar, B. Graphene and temperature controlled butterfly shape in permittivity-field loops of ferroelectric polymer nanocomposites 2017 Applied Physics Letters
Vol. 110(2) 
article DOI URL 
Abstract: We report on the field-dependent polarization of graphene (GE) filled poly[vinylidene fluoride-co-trifluoroethylene] P(VDF-TrFE) nanostructures fabricated by mechanical melt mixing. This study shows an increase in effective permittivity of these nanomaterials on increasing the GE loading in a manner that is consistent with standard mixing law. Detailed characterization of the unsaturated ferroelectric hysteresis, as well as the butterfly shape of the effective permittivity versus electric bias, of the samples are presented. For GE content set to 9.1 wt. % in the samples containing 50/50 wt. % (VDF/TrFE), the maximum polarization increases by 260% with respect to that of the neat polymer matrix. With a higher VDF content, 73 wt. %, the coercive field remains constant over the range of GE content explored. Additionally, our results highlight the strong impact of the GE loading and temperature on the butterfly shape in permittivity-field loops of these nanocomposites. The experimental findings are consistent with theoretical predictions of the modified Johnson's model [Narayanan et al., Appl. Phys. Lett. 100, 022907 (2012)]. Our findings can open avenues for interplay between conductive nanofillers and ferroelectricity in soft nanomaterials with controlled phase transitions. © 2017 Author(s).

Azahelicenes as visible light photoinitiators for cationic and radical polymerization: Preparation of photoluminescent polymers and use in high performance LED projector 3D printing resins 2017 J. Polym. Sci., Part A: Polym. Chem.(55)  article DOI URL 
Abstract: In this article, novel azahelicenes (AZs) were synthesized and proposed as high performance visible light photoinitiators for both the free radical polymerization of acrylates and the cationic polymerization (CP) of epoxides upon visible light exposure using Light Emitting Diodes (LEDs) @405, @455, and @470 nm. Excellent polymerization initiating abilities are found and high final conversions were obtained. Remarkably, an exceptional long lifetime photoluminescence property of the polymer films was observed when synthesized in presence of AZs. A full picture of the involved chemical mechanisms is given. AZs being high performance photoinitiators, their use in new cationic LED 3D printing resins will be also presented, that is, the cationic process upon LED projector @405 nm can be useful to reduce the shrinkage usually observed for radical polymerization. LED projector printing is very interesting compared to laser writing as this technology projects the profile of an entire layer of a 3D object at one time. © 2017 Wiley Periodicals, Inc.

Copper photoredox catalysts for polymerization upon near UV or visible light: structure/reactivity/efficiency relationships and use in LED projector 3D printing resins 2017 Polym. Chem.
Vol. 8(3), pp. 568-580 
article URL 
Abstract: Copper complexes (CuCs) bearing pyridine-pyrazole ligands are synthesized and evaluated as new photoredox catalysts/photoinitiators in combination with an iodonium salt (Iod) for the free radical polymerization of (meth)acrylates and the cationic polymerization of epoxides upon visible light exposure using a Light Emitting Diode (LED)@405 nm. The structure/reactivity/efficiency relationships for the copper complexes are studied as well as the chemical mechanisms involved. The different substituents on the pyrazole moiety of the ligand allow tuning of the oxidation potential and the visible light absorbance of the complexes and to optimize the performance of the polymerization photoredox catalysts. The use of a novel additive (CARET) in a three-component system (CuC/Iod/CARET) highly improves the performance. Finally, the high performances of the Cu(i) complexes for the development of new 3D printing resins using an LED projector are demonstrated. Currently, LED projector printing is really advantageous in 3D printing i.e. this technology projects the profile of an entire layer at one time.

Carbazole Scaffold Based Photoinitiator/Photoredox Catalysts: Toward New High Performance Photoinitiating Systems and Application in LED Projector 3D Printing Resins 2017 Macromolecules
Vol. 50(7), pp. 2747-2758 
article DOI  
Abstract: Four new carbazole derivatives (C1-C4) are synthesized and proposed as high performance visible light photoinitiators/photoredox catalysts for both the free radical polymerization (FRP) of (meth)acrylates and the cationic polymerization (CP) of epoxides upon visible light exposure using light-emitting diodes (LEDs) at 405, 455, and 477 nm. Excellent polymerization initiating abilities are found, and high final reactive function conversions are obtained. Interestingly, these new derivatives exhibit much better visible light polymerization initiating ability compared to a reference UV-absorbing carbazole (CARET, 9H-carbazole-9-ethanol) showing that the new substituents are of great interest to red-shift the absorption of the proposed photoinitiators. More remarkably, in combination with an iodonium salt, C1-C4 are also better than the well-known bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide (BAPO) photoinitiator for mild irradiation conditions highlighting their outstanding reactivity. Their use in new cationic resins for LED projector 3D printing is particularly outlined. A full picture of the involved photochemical mechanisms is provided. Originally, these carbazoles behave as metal-free photoredox catalysts active in both oxidative and reductive cycles.

Abstract: Zinc tetraphenylporphyrin (ZnTPP) is proposed as a high performance visible light photoinitiator for both the free radical polymerization (FRP) of methacrylates (thick films) and the cationic polymerization (CP) of epoxides (thin films) upon visible light exposure using light emitting diodes (LEDs) at 405, 455, 477, and S30 nm. ZnTPP combined with an iodonium salt shows excellent polymerization initiating abilities and high final conversions were obtained. Remarkably, for the ligand alone (tetraphenylporphyrin derivative, H2TPMP) used as photoinitiator, no polymerization occurs, indicating the importance of the metal in the initiating complex for an efficient process. A full picture of the involved chemical mechanisms is given. The high performance of ZnTPP as cationic initiating system is also well shown for new cationic 3D printing resins upon exposure to LED projector at 405 nm.

Vol. 2, pp. 1-10 
article DOI  
Abstract: Background: Symmetrically substituted pentacenes have been traditionally used as semiconductors for solution-processed p-channel Organic Field Effect Transistors (OFETs). The aims of this paper are to introduce asymmetrically substituted pentacenes in the active layer and to examine the impact of the polyaromaticity of the pendant groups of the device characteristics.

Methods: Research and online content related to asymmetrically substituted pentacenes is reviewed, the synthesis of the different pentacenes is described and the procedure used to introduce these semiconductors in devices is detailed. Comparison with a reference material is provided.

Results: Extension of the polyaromaticity of the pendant group of pentacene greatly contributes to enhance the device performances. Impact of the pendant group on the morphology of the active layer is evidenced roughness decreasing with the increase of aromatic ring in the substituent.

Conclusion: We demonstrate the extension of the π-conjugation of the aromatic end-group to drastically impact both ION/IOFF ratio and charge carrier mobilities, mainly due to various degree of crystal formation characteristics in the film. Best results were obtained with the most extended one, namely the anthracene moiety which showed a mobility comparable to that of the benchmark TIPSpentacene with OFETs that used hexamethyldisilazane as the gate dielectric passivation layer.

Abstract: We report on a fast synthesis method of porous carbon films on solid substrates. Thin carbon microstructures tailored by processing conditions were synthesized for the first time by Matrix-Assisted Pulsed Laser Evaporation. The procedure consists of pulsed laser irradiation of a cryogenic target composed of phloroglucinol/glyoxylic acid organic precursors dissolved in different mixtures of solvents. An excimer UV KrF* pulsed laser was employed inside a vacuum chamber for material expulsion from the target and immobilization on a solid facing collector. By modifying laser energy or target solvents, thin polymeric coatings of hundreds of nanometers with various cross-linking degrees were obtained at room temperature in 10 min only. No drying or thermo-polymerization step is required even for high boiling point solvents such as dymethyl sulfoxide (DMSO). After thermal treatment, mesoporous carbon films exhibiting diverse nano-morphologies and surface areas up to 705 m(2) g(-1) determined by Kr adsorption were then directly obtained onto various collectors. Processing and assembling mechanisms of phenolic resins were investigated and two competing mechanisms, e.g., target absorption of laser wavelength and subsequent molecules transfer/interactions are accounted for the growth of high quality films as highlighted by several techniques.

Balan, L., de Cordoba, M.C.F., Zaier, M. and Ania, C.O. A green and fast approach to nanoporous carbons with tuned porosity: UV-assisted condensation of organic compounds at room temperature 2017 Carbon
Vol. 116, pp. 264-274 
article DOI  
Abstract: This work reports a green and fast approach to the synthesis of nanoporous carbon materials based on the UV-assisted condensation of organic compounds as precursors. This new approach offers several improvements over the classical soft template and sol-gel routes for the synthesis of materials: versatility of organic precursors, shorter synthesis time, and ambient conditions. Owing to the specificity of the UV assisted reactions mechanisms, organic compounds of varied chemical composition can be used as precursors in the preparation of nanoporous carbons with tuned porous features. The method consisted in the exposure of an aqueous solution of the organic precursors to UV light for 60 min at room temperature in the absence of a catalyst, allowing an outstanding shortening of the synthesis time compared to sol-gel routes. Furthermore, UV irradiation promoted the cross-linking of the polymer chains of precursors at room temperature, as opposed to classical methods that require an additional step at mild/high temperatures. By changing the chemistry of the organic compound used as precursor, it was possible to modulate the surface area (from 10 to 720 m(2) g(-1)) and the porosity of the synthesized carbons within the micro-/mesopore range. The obtained carbons also presented varied morphology depending on the precursor, from dense aggregates to ordered hexagonal arrangements of nanometric dimensions. (C) 2017 The Authors.

Vol. 23(54), pp. 13342-+ 
article DOI  
Abstract: We report a new class of functionalized polylutidine polymers that are prepared by chemical vapor deposition polymerization of substituted [2](1,4)benzeno[2](2,5)pyridinophanes. To prepare sufficient amounts of monomer for CVD polymerization, a new synthesis route for ethynylpyridinophane has been developed in three steps with an overall yield of 59%. Subsequent CVD polymerization yielded well-defined films of poly(2,5-lutidinylene-co-p-xylylene) and poly(4-ethynyl-2,5-lutidinylene-co-p-xylylene). All polymers were characterized by infrared reflection-absorption spectroscopy, ellipsometry, contact angle studies, and X-ray photoelectron spectroscopy. Moreover, zeta-potential measurements revealed that polylutidine films have higher isoelectric points than the corresponding poly-xylylene surfaces owing to the nitrogen atoms in the polymer backbone. The availability of reactive alkyne groups on the surface of poly(4-ethynyl-2,5-lutidinylene-co-p-xylylene) coatings was confirmed by spatially controlled surface modification by means of Huisgen 1,3-dipolar cycloaddition. Compared to the more hydrophobic poly-p-xylylyenes, the presence of the heteroatom in the polymer backbone of polylutidine polymers resulted in surfaces that supported an increased adhesion of primary human umbilical vein endothelial cells (HUVECs). Vapor-based polylutidine coatings are a new class of polymers that feature increased hydrophilicity and increased cell adhesion without limiting the flexibility in selecting appropriate functional side groups.

Abstract: Reaction of condensation and cross-linking of catechin monomer as a model of condensed (flavonoid) tannin extracts and of mimosa tannin itself, as well as of resorcinol with triethyl phosphate (TEP) have been investigated. FTIR, solid state CP-MAS C-13 NMR, P-31 NMR and MALDI-ToF spectroscopy studies revealed that reaction occurs mainly on the C3 of the flavonoid heterocycle ring and on the aromatic C4' and C5' carbons of the flavonoids B-ring, while TEP does not appear to react on the A-ring. A difference in the relative proportions of these two reaction sites for tannin and catechin has been noticed. The reactions appear to be dependent on the temperature. According to the thermogravimetric analysis, materials obtained from the reaction of tannin with TEP showed high thermal stability. (C) 2016 Elsevier B.V. All rights reserved.

Vol. 121(34), pp. 18725-18737 
article DOI  
Abstract: A series of beta-zeolites with different sizes have been synthesized. Their size range from 10 mu m to a few nanometers. The acidity measurement (i.e number, strength and location) were carried out by so-called conventional techniques: adsorption followed by infrared spectroscopy of various basic probe molecules (CO, C2H4, pyridine) and model reaction (n-hexane cracking). The extreme crystal downsize lowers the acid strength. These results are confirmed also by using an innovative technique: the reversed-flow inverse chromatography (RF-IGC). The involvement of the external and internal zeolitic species depend on the adsorbed molecules and the operating conditions: (i) the high content of extra-framework aluminum enhance the n-hexane cracking activity owing to the exaltation of the Bronsted sites strength, and (ii) the RF-IGC technique show an important involvement of the silanol groups (mainly present on the nanosized zeolite) in lateral interactions with ethylene.

Abstract: The adsorption and diffusion are key parameters for the catalytic conversions of ethylene to hydrocarbons. Using microcrystals of beta zeolites and the reversed-flow inverse gas chromatography technique, a new approach is developed for the catalytic characterization of pristine crystals. On the basis of the monitoring of the dynamic concentration in a time-resolved way, this method allows one to follow the surface coverage and adsorption energies among other physicochemical criteria. Pristine crystals were synthesized to rule out the effect of surface defects. The impact of porosity and acidity was studied by ethylene adsorption over porous, nonporous, and acid materials. The acidity of the mother zeolite (acid and porous) was decreased by retro-exchanges and partial cokage. The modification of the ethylene sorption due to the Brønsted acidity was then highlighted. The local surface coverage was not affected by the presence of porosity, while a second adsorption phase of the ethylene was induced by the modification of the acidity. Moreover, a relation between the amount of Brønsted acidity and the ethylene lateral interactions measured by RF-IGC was evidenced.

Structure-performance relationship in CuO/SBA-15-type SOx adsorbent: evolution of copper-based species under different regenerative treatments 2017 Catalysis Science & Technology
Vol. 7(18), pp. 4115-4128 
article DOI  
Abstract: Sulphur oxides (SOx) represent a major air pollutant and are controlled by national and international regulations. CuO/SiO2 materials are known as SOx trap materials. However, their large-scale development is still hampered by the sintering of the active phase over multiple adsorption/regeneration cycles, leading to the progressive decrease in SOx adsorption capacities of the adsorbent. In this work, SBA-15 organised mesoporous silica was functionalized with highly dispersed Cu2+-based species. The as-obtained adsorbent was then assessed as a regenerable SOx trap material. An extended characterisation was performed along with adsorption/regeneration cycles to correlate the evolution of the copper species with the performance of the adsorbent under different regenerative treatments. Thermal regeneration at 600 degrees C under pure N-2 leads to the formation of Cu+-based species, enabling a significant increase in SOx chemisorption efficiency, which nevertheless decreases during the subsequent cycles due to progressive sintering of the active phase, leading to bulky copper.II) oxide particles. Regeneration under reductive conditions (0.5 vol% of H-2 in N-2) was then investigated as a way to decrease the regeneration temperature and limit this sintering process. It was found that the general behaviour of the copper-based species was very sensitive to the regeneration temperature. At 600 degrees C, the active phase was completely converted into large metallic copper particles, giving rise to a fast decrease in SOx adsorption capacity of the adsorbent due to partial obstruction of the SBA-15 silica porosity. Conversely, when this regeneration was performed at 280 degrees C, no decrease in performances was noticed, and the copper species remained as a highly dispersed phase on the silica support.

Abstract: The oxidation behavior of carbon materials has been investigated at temperatures less than 773 K using isothermal thermogravimetric analyses under dry and wet air. Bulk samples obtained by the pyrolysis of phenolic resin have been characterized using X-ray diffraction and elementary analysis. X-ray photoelectron spectroscopy and Raman spectroscopy have been performed to analyze the surface and subsurface. The carbon structure has a poor organization state and a gradient in the oxygen concentration and structure between the surface and the bulk is revealed. The material is more reactive under wet air than dry air in terms of oxidation rates as determined between 623 and 773 K. The apparent activation energies are respectively 122 +/- 6 kJ/mol in dry air and 102 +/- 6 kJ/mol in wet air. (C) 2016 Elsevier B.V. All rights reserved.

Vol. 17(3), pp. 1173-1179 
article DOI  
Abstract: Despite having been used in hydrocracking processes for decades, zeolite Y is still nowadays the subject of intense research aiming at improving its physicochemical properties. Here, and for the first time, the synthesis of zeolite Y nanocrystals prepared in organic template-free medium, featuring both extremely reduced dimensions (mean diameter below 30 nm) and a high silicon to aluminum ratio (Si/Al approximate to 2.2), is reported. The singularity of the protocol lies in the progressive adding of a silica source during synthesis combined with the use of prolonged aging times. These high-silica ultra-nanosized zeolite Y crystals display excellent textural properties (V-micropore = 0.33 cm(3)/g and S-BET = 830 m(2)/g), comparable to their microsized counterparts. In this work, the extensive study of the influence of various parameters (i.e., gel composition, aging time, and crystallization conditions) intended for the optimization of the synthesis protocol is also presented.

Vol. 66(4), pp. 504-511 
article DOI  
Abstract: The objective of this work was to propose a novel low migration additive (i.e. a phosphine) to overcome the oxygen inhibition in a camphorquinone (CQ) base photoinitiating system for the polymerization of methacrylates (e.g. a bisphenol A-glycidyl methacrylate (Bis-GMA)/triethyleneglycol dimethacrylate (TEGDMA) blend (70%/30% w/w)) upon exposure to a commercial blue light emitting diode centred at 477 nm. CQ/amine/phosphine derivative or CQ/amine/iodonium salt/phosphine derivative combinations were studied. Real-time Fourier transform IR and photo-DSC experiments were used to monitor the polymerization profiles. Remarkably, it was found that the addition of the new phosphine derivative to CQ/amine or CQ/amine/iodonium salt noticeably improved the rate of polymerization and the final conversion in air. A low migration was found for this additive as shown by HPLC experiments in agreementwith a copolymerizable behaviour. No additional yellowing of the film was observed. Electron spin resonance spectrometry was used to detect the produced radicals. The overall chemical mechanisms are investigated and discussed. (C) 2016 Society of Chemical Industry

Silyl Glyoxylates as a New Class of High Performance Photoinitiators: Blue LED Induced Polymerization of Methacrylates in Thin and Thick Films 2017 Macromolecules
Vol. 50(17), pp. 6911-6923 
article DOI  
Abstract: Silyl glyoxylates are proposed here as a new class of high performance type I photoinitiators for free radical polymerization under air or in laminate (e.g., (meth)acrylates) upon exposure to different near-UV (at 395 ma; at 405 nm) and blue (at 477 nm) LEDs. The new proposed photoinitiators can also be used in the presence of additives that can enhance their initiating ability: an iodonium salt and an amine or a phosphine. The silyl glyoxylate-based photoinitiating systems exhibit excellent polymerization performances upon blue LED light (at 477 run) with exceptional bleaching properties compared to camphorquinone (CQ)-based systems. This can be highly worthwhile for the preparation of colorless polymers upon visible light. Real-time Fourier transform infrared spectroscopy (RT-FTIR) experiments are used to monitor the polymerization profiles. The involved chemical mechanisms are investigated by fluorescence, laser flash photolysis, electron spin resonance (ESR), and steady state photolysis experiments. Molecular orbital calculations are also carried out. The overall excited state processes and the chemical mechanisms involved in the initiation step are detailed.

Brioude, M.M., Laborie, M.-P., Airoudj, A., Haidara, H. and Roucoules, V. Stability of maleic anhydride plasma polymer film to water drop evaporation 2017 Plasma Processes and Polymers
Vol. 14(8), pp. e1600195 
article DOI  
Abstract: Previous work revealed the possibility of controlling the nanostructuration of maleic anhydride plasma polymer (MAPP) by adjusting the plasma process parameters or adding cellulose nanocrystals (CNCs) previously on the substrate. This work aimed to evaluate the stability of MAPP coating to water drop evaporation. The evaporation process was followed by optical microscopy and the effects of substrate surface chemistry and presence of CNCs were investigated. The presence of CNCs affected not only the MAPP adhesion under wet condition, leading to an impressive morphological reconstruction of MAPP coating, but also the evaporation kinetics. Therefore, this work exhibits a simple way to obtain functional surface patterns by changing the coating wet adhesion and opens new opportunities for the utilization of CNCs.

Vol. 55(9), pp. 721-728 
article DOI URL 
Abstract: We investigate the spontaneous rolling of polydimethylsiloxane (PDMS) thin films and demonstrate the fabrication of capillaries with topographical and chemical patterns on the inner wall. Thin films of PDMS are either coated by a layer of hard material or have their surface hardened by plasma oxidation. They are then driven out of equilibrium by selective solvent swelling in vapor phase resulting in a tubular rolled-up system. The inner diameter of those is measured as a function of layer thickness for different solvents and capping types. Those results are shown to be in good agreement with Timoshenko theory. Before rolling, the future inner surface can be characterized and functionalized. We demonstrate topographical and chemical patterning, respectively by embossing and microcontact printing. These methods are very simple and can easily produce cylindrical capillaries with inner diameter between 20 and some hundreds of microns with fully functionalized inner surface, overcoming many difficulties encountered in conventional soft lithography techniques. © 2017 Wiley Periodicals, Inc.

Vol. 7, pp. 9247 
article DOI  
Abstract: Mammalian cells have been widely shown to respond to nano-and microtopography that mimics the extracellular matrix. Synthetic nano-and micron-sized structures are therefore of great interest in the field of tissue engineering, where polymers are particularly attractive due to excellent biocompatibility and versatile fabrication methods. Ordered arrays of polymeric pillars provide a controlled topographical environment to study and manipulate cells, but processing methods are typically either optimized for the nano-or microscale. Here, we demonstrate polymeric nanopillar (NP) fabrication using 3D direct laser writing (3D DLW), which offers a rapid prototyping across both size regimes. The NPs are interfaced with NIH3T3 cells and the effect of tuning geometrical parameters of the NP array is investigated. Cells are found to adhere on a wide range of geometries, but the interface depends on NP density and length. The Cell Interface with Nanostructure Arrays (CINA) model is successfully extended to predict the type of interface formed on different NP geometries, which is found to correlate with the efficiency of cell alignment along the NPs. The combination of the CINA model with the highly versatile 3D DLW fabrication thus holds the promise of improved design of polymeric NP arrays for controlling cell growth.

Vol. 23(1), pp. 101-112 
article DOI  
Abstract: The influence of sodium cations content in zeolite Beta crystals of different sizes (between 200 nm and 2 mu m) on the adsorption of pollutants (dioxin and polychlorobenzene) is investigated. In this study, protons which balance the negative charge of the zeolitic framework are partially replaced by sodium cations. Chemical, structural and textural analyses performed on the exchanged crystals indicate that the exchange rates reached 75-80 % and that the structure of zeolites is preserved. Adsorptions of pollutants in zeolite Beta samples were successfully carried out using 1,2-dichlorobenzene (gas phase) and 2,3-DiChloroDibenzo-p-Dioxin: 2,3-DCDD (liquid phase) but reveal different behaviors. Indeed, all samples adsorb the same amount (around 7 molecules) of 1,2-dichlorobenzene per unit-cell of zeolite, whereas the dioxin adsorption amounts increase with the amount of sodium cations. Compared to their protonic forms, the dioxin adsorption capacities were multiplied by a factor of 1.3 for the sodium exchanged small crystals (size between 200 nm and 1 mu m) and by a factor of 4 for the sodium exchanged microcrystals (size between 1 and 2 mu m) for an equilibrium concentration of 2,3-DCDD of 0.5 mmol/L in both cases.

Adsorption of 1,2-dichlorobenzene and 1,2,4-trichlorobenzene in nano- and microsized crystals of MIL-101(Cr): static and dynamic gravimetric studies. 2017 Environmental science and pollution research international  article DOI  
Abstract: This work aims to highlight the promising adsorption capacity and kinetic of (poly)chlorobenzene pollutants in the hybrid MIL-101(Cr) type material for technological uses in industrial waste exhaust decontamination. The influence of the MIL-101(Cr) crystal size (nano- and microcrystals) on the adsorption behavior was studied in static and dynamic modes. For this purpose, crystals of MIL-101(Cr) in nano- and micrometric sizes were synthesized and fully characterized. Their sorption properties regarding 1,2-dichlorobenzene were examined using gravimetric method in dynamic (p/p°=0.5) and static (p/p°=1) modes at room temperature. 1,2,4-trichlorobenzene adsorption was only performed under static mode because of its too low vapor pressure. 1,2-dichlorobenzene and 1,2,4-trichlorobenzene were used to mimic 2,3-dichlorodibenzo-p-dioxin and 1,2,3,4-tetrachlorodibenzo-p-dioxin, respectively, and more largely dioxin compounds. Adsorptions of these probes were successfully carried out in nano- and microcrystals of MIL-101(Cr). Indeed, in static mode (p/p°=1) and at room temperature, nanocrystals adsorb 2266 molecules of 1,2-dichlorobenzene and 2093 molecules of 1,2,4-trichlorobenzene per unit cell, whereas microcrystals adsorb 1871 molecules of 1,2-dichlorobenzene and 1631 molecules of 1,2,4-trichlorobenzene per unit cell. In dynamic mode, the 1,2-dichlorobenzene adsorbed amounts are substantially similar to those obtained in static mode. However, the adsorption kinetics are different because of a different scheme of diffusivity of the adsorbate between the two modes. To the best of our knowledge, these adsorption capacities of MIL-101(Cr) as adsorbent for polychlorobenzenes trapping have never been referenced. MIL-101(Cr) appears as a promising material for technological uses in industrial waste exhaust decontamination.

Cabannes-Boue, B., Yang, Q.Z., Lalevee, J., Morlet-Savary, F. and Poly, J. Investigation into the mechanism of photo-mediated RAFT polymerization involving the reversible photolysis of the chain-transfer agent 2017 Polymer Chemistry
Vol. 8(11), pp. 1760-1770 
article DOI  
Abstract: A new dithiocarbamate with a N-carbazole Z group is synthesized and investigated as a chain-transfer agent (CTA) in a photo-mediated RAFT polymerization mechanism involving its partial and reversible photolysis. Excellent control of the polymerization of butyl acrylate is observed using LEDs as light sources emitting either in the blue or green wavelength domain. As a photo-mediated reversible deactivation radical polymerization (RDRP) mechanism, the polymerization can be easily stopped or reinitiated by simply switching off or on the light source. This behavior is exploited for subsequent chain-extensions of macroCTAs. A simple kinetic modeling is then proposed, which can support the trends observed experimentally, such as the effects of light intensity and wavelength on the apparent polymerization rate. The developed equation suggests also ways to improve the control of the polymerization by playing on the photolysis pseudo-equilibrium, while underlying the importance of the quantum yield of photodissociation of the CTA.

Abstract: The new zincophosphate of chemical formula [C6H10N2][ZnP2O8H2]∙0.6H2O was hydrothermally synthesized with p-phenylenediamine as structure-directing agent. The titled compound crystallizes in the trigonal symmetry (proposed space group P-3m1) where inorganic zincophosphate chains form layers due to the half occupancy of the unique crystallographic zinc site. The layers are separated from each other by p-phenylenediammonium dications with a hydrogen-bonding scheme involving the ammonium protons that reveals a pillar-like 3D structure aspect. The compound was characterized by powder X-ray diffraction, multinuclear solid-state NMR, scanning electron microscopy, chemical analysis and thermogravimetric analysis.

Vol. 409, pp. 102-110 
article DOI  
Abstract: Al-doped ZnO (ZnO:Al) rods with Al doping varying from 0 to 20% were successfully prepared via a solvothermal method. ZnO:Al rods exhibit the hexagonal wurtzite crystalline structure and their length were found to decrease from 127 to 12 nm when increasing the dopant percentage from 0 to 20%. Simultaneously, their specific surface area increased from ca. 21 to 82 m(2)/g. ZnO:Al (20%) rods exhibit high adsorption capability towards some negatively charged dyes like Orange II, Acid red 88 or Alizarin, which was attributed to the high specific surface of ZnO:Al rods and to the defects induced by the Al doping as demonstrated by XRD and Raman spectroscopy.

Vol. 11(1), pp. 627-634 
article DOI  
Abstract: Based on a low-temperature scanning tunneling microscopy study, we present a direct visualization of a cycloaddition reaction performed for some specific fluorinated maleimide molecules deposited on graphene. Up to now, it was widely admitted that such a cycloaddition reaction can not happen without pre-existing defects. However, our study shows that the cycloaddition reaction can be carried out on a defect-free basal graphene plane at room temperature. In the course of covalently grafting the molecules to graphene, the sp(2) conjugation of carbon atoms was broken, and local sp(3) bonds were created. The grafted molecules perturbed the graphene lattice, generating a standing-wave pattern with an anisotropy which was attributed to a (1,2) cycloaddition, as revealed by T-matrix approximation calculations. DFT calculations showed that while both (1,4) and (1,2) cycloadditions were possible on free-standing graphene, only the (1,2) cycloaddition could be obtained for graphene on SiC(0001). Globally averaging spectroscopic techniques, XPS and ARPES, were used to determine the modification in the elemental composition of the samples induced by the reaction, indicating an opening of an electronic gap in graphene.

Vol. 6(2), pp. 117-120 
article DOI URL 
Abstract: New polysilsesquioxane-based lamellar materials, functionalized with radical precursors, were synthesized. They play a double role in the preparation of composite materials: first, as filler homogeneously dispersed in the monomer after delamination, second as radical initiator in photopolymerization. These polysilsesquioxanes enable fast and efficient photopolymerization upon UV light for thick samples. High conversions in monomers as well as the formation of hybrid polymers covalently linked to the filler are observed. This strategy, based on a double bottom-up approach, avoids the solubility/dispersion problem encountered in the classical preparation of composite polymers from preformed organic polymers.

Humidity-induced formation of water channels in supramolecular assemblies of wedge-shaped amphiphiles: the effect of the molecular architecture on the channel topology 2017 Physical Chemistry Chemical Physics
Vol. 19(11), pp. 7714-7720 
article DOI  
Abstract: In supramolecular assemblies, absorption of water can assist the channel formation, similarly to biological systems and Nafion-like commercial ion-selective membranes. In this work, we investigate humidity-induced formation of water channels in wedge-shaped amphiphilic molecules, namely sodium 40-[ 3",4",5"- tris(alkyloxy)benzoyloxy]azobenzene-4-sulfonates. The studied molecules contain a polar sulfonate group at the tip and a hydrophobic periphery composed of alkyl chains of two different lengths. Upon increasing the relative humidity (RH) the amount of absorbed water significantly increases for the mesogen with dodecyl chains as compared to the one with octyl groups. In the former case, water sorption is accompanied by a considerable enhancement of ionic conductivity and a phase transition. In particular, an increase of RH induces a transition from a lamellar to a columnar phase resulting in the formation of 1D water channels running along the axis of the supramolecular columns. For the compound with shorter alkyl chains the lamellar phase exists in the entire RH-range exhibiting pronounced swelling at high RH-values and thereby forming a 2D water channel structure. NMR diffusometry was used to address the different molecular motions in the lyotropic mesophases of the studied amphiphiles.

Vol. 121(42), pp. 23422-23435 
article DOI  
Abstract: After radionuclide pollution of soils by nuclear power plant accidents, Cs+] strongly interacts with swelling clay minerals, which in turn controls the fixation or the migration of this pollutant in the natural media. Little is known, however, about the role played by the amount of layer charge and the two-dimensional confinement on Cs+ fixation. In this study a series of tetrahedrally charged smectites with structural formula (mter)[M-x(+)](oct) [Mg-6 ](tet) [Si8-xAlx]O-20(OH)(4) and with a layer charge (x) varying from 0.8 to 2.0 and with Na+ or Cs+ as interlayer cation 1+ were used. While Na+ remains fully exchangeable over the entire range of layer charges investigated, the fraction of exchangeable Cs+ decreased gradually for samples with x >= 1.4/O-20(OH)(4). Structure analysis of Cs+-samples in water-saturated or at 80% relative humidity conditions showed a gradual decrease of the layer-to-layer distance. The results were found to qualitatively agree with analysis of the thermodynamics of the clay/water interfaces derived from molecular simulations. Quantitative structure analysis by modeling of 00l reflections on experimental X-ray diffraction patterns suggested that exchangeable Cs+ can be correlated with the amount of hydrated interlayers, whereas fixed Cs+ in these conditions corresponds to the amount of collapsed layers. To describe the coexistence of both exchangeable and fixed Cs+, a toy model accounting for the presence of heterogeneous charge distribution was used, in agreement with experimental data obtained on these samples. This model successfully interprets the overall reactivity of Cs' toward smectite over a large range of layer charge Values and may contribute to an improved description of ce mobility in contaminated soil environments.

Synthesis and characterization of Ti-27.5Nb alloy made by CLAD (R) additive manufacturing process for biomedical applications 2017 Materials Science & Engineering C-materials for Biological Applications
Vol. 75, pp. 341-348 
article DOI  
Abstract: Biocompatible beta-titanium alloys such as Ti-27.5(at.%)Nb are good candidates for implantology and arthroplasty applications as their particular mechanical properties, including low Young's modulus, could significantly reduce the stress-shielding phenomenon usually occurring after surgery. The CLAD process is a powder blown additive manufacturing process that allows the manufacture of patient specific (i.e. custom) implants. Thus, the use of Ti-27.5(at.%)Nb alloy formed by CLAD process for biomedical applications as a mean to increase cytocompatibility and mechanical biocompatibility was investigated in this study. The microstructural properties of the CLAD-deposited alloy were studied with optical microscopy and electron back-scattered diffraction (EBSD) analysis. The conservation of the mechanical properties of the Ti-27.5Nb material after the transformation steps (ingot-powder atomisation-CLAD) were verified with tensile tests and appear to remain close to those of reference material. Cytocompatibility of the material and subsequent cell viability tests showed that no cytotoxic elements are released in the medium and that viable cells proliferated well. (C) 2017 Elsevier B.V.

Vol. 55(21), pp. 3646-3655 
article DOI  
Abstract: The first use of a new mechanosynthesized copper complex (Cu(acac)(2dppba)) as a initiator for the redox and redox photoactivated polymerization of methacrylates under air is proposed. This paper (i) describes the mechanosynthesis of this complex, (ii) outlines the relative efficiency of the complex for redox polymerization (mechanosynthesized product vs. solvent synthesized product), (iii) follows the polymerization enhancement under a 405 nm light, and (iv) demonstrates the high performance of this complex in near infrared photoactivated redox polymerization where a completely colorless polymer is obtained (unprecedented under NIR irradiations, 785 nm, here). The light activated polymerization exhibit higher conversions, better time controls (activation control) and higher surface conversions than redox polymerization. The mechanosynthesis is well characterized by two solvent-free methods (visual color change and Electron Spin Resonance) and two solvent-based methods (high resolution-electrospray ionization-mass spectrometry (HR-ESI-MS) and UV-vis spectrometry). The involved mechanisms are discussed. Mechanosynthesis of copper complexes opens new perspectives for copper (photo)redox polymerization catalysts as the environmental impact and economical costs of the complex synthesis are significantly reduced.

Vol. 8(38), pp. 5884-5896 
article DOI  
Abstract: Significant improvements of the recently proposed Cu(I)/vitamin C + water/dibenzoyl peroxide (BPO) system for the redox free radical polymerization of methacrylates in air are presented here, the goal being to avoid the presence of water and to eliminate the unstable BPO compound. Additionally, the use of mechanosynthesized Cu(I) complexes bearing cheap triphenylphosphine and methylpyridine ligands, allowed us to reduce the economical and synthesis costs significantly. Water-free reducing agents such as 6-O-palmitoyl-L-ascorbic acid, organotin or hydrazine derivatives are evaluated. Cumene hydroperoxide and tert-butyl perbenzoate are proposed as a replacement for less stable BPO. Most of these novel combinations are more efficient in air than the usual amine/benzoylperoxide system (4-N, N-TMA/BPO) reference especially at the sample surface. Among them, Cu(I)/organotin/cumene hydroperoxide appears as an efficient and competitive alternative to the conventional amine/BPO couple.

Abstract: Meso- and macroporous tungsten disulfide (WS2) and tungsten nitride (W2N) powders were successfully synthesized by reduction of [WO3/colloidal silica] composites under hydrogen sulfide and ammonia gases respectively. The colloidal silica, marketed as Ludox®, was used as a hard template and its removal from the composite led to a porosity release. The products were characterized by X-ray diffraction, nitrogen adsorption, mercury porosimetry and electron microscopy. Well-crystallized samples with specific surfaces areas close to  40 m2 g−1 were thus synthesized. The present approach might be easily extended to the synthesis of other nitrides and sulfides materials. © 2016 Elsevier Ltd and Techna Group S.r.l.

Guizani, C., Haddad, K., Limousy, L. and Jeguirim, M. New insights on the structural evolution of biomass char upon pyrolysis as revealed by the Raman spectroscopy and elemental analysis 2017 Carbon
Vol. 119, pp. 519-521 
article DOI URL 
Abstract: The influence of pyrolysis conditions on the structure properties and chemical composition of biomass chars was examined. The Raman spectroscopy ID/IG and IV/ID parameters were found to be correlated for pyrolysis temperatures higher than 600 °C. Furthermore, a correlation between IV/ID and the atomic ratio (O+H)/C was identified. These findings would corroborate the assumption that the large carbonaceous structures having defects (D band) would probably form from the condensation of the small amorphous ones (V region). The condensation of these small structures into larger ones would be accompanied by the release of H and O atoms into the gas phase. © 2017 Elsevier Ltd

Guizani, C., Jeguirim, M., Valin, S., Limousy, L. and Salvador, S. Biomass Chars: The Effects of Pyrolysis Conditions on Their Morphology, Structure, Chemical Properties and Reactivity 2017 Energies
Vol. 10(6), pp. 796 
article DOI  
Abstract: Solid char is a product of biomass pyrolysis. It contains a high proportion of carbon, and lower contents of H, O and minerals. This char can have different valorization pathways such as combustion for heat and power, gasification for Syngas production, activation for adsorption applications, or use as a soil amendment. The optimal recovery pathway of the char depends highly on its physical and chemical characteristics. In this study, different chars were prepared from beech wood particles under various pyrolysis operating conditions in an entrained flow reactor (500-1400 degrees C). Their structural, morphological, surface chemistry properties, as well as their chemical compositions, were determined using different analytical techniques, including elementary analysis, Scanning Electronic Microscopy (SEM) coupled with an energy dispersive X-ray spectrometer (EDX), Fourier Transform Infra-Red spectroscopy (FTIR), and Raman Spectroscopy. The biomass char reactivity was evaluated in air using thermogravimetric analysis (TGA). The yield, chemical composition, surface chemistry, structure, morphology and reactivity of the chars were highly affected by the pyrolysis temperature. In addition, some of these properties related to the char structure and chemical composition were found to be correlated to the char reactivity.

Vol. 5(10), pp. 8988-8996 
article DOI  
Abstract: This investigation has established a complete environmentally friendly strategy for the valorization of olive mill wastewater (OMW). This valorization process includes different steps, namely, OMW impregnation on sawdust, drying, biofertilizer production, and soil amendment. The OMW impregnation on raw cypress sawdust (RCS) was performed using batch procedure mode. During this impregnation, 59% and 71% of the chemical oxygen demand and total dissolved salts of OMW were adsorbed on RCS. The drying of the impregnated sawdust (IS) and OMW was realized in a convective dryer at temperature ranging between 40 and 60 degrees C and air velocity ranging between 0.7 and 1.3 m/s. Comparison between both samples demonstrated clearly that the impregnation procedure accelerated the drying process and consequently allowed an ecologic recovery of water from OMW that could be reused. The IS sample was pyrolyzed at 500 degrees C for green fuel (bio-oil, gas) and char production. This residual char (IS-Char) exhibited higher mass fraction of 34.5%. The IS char characterization showed the presence of important nutrients (potassium, nitrogen, and phosphorus) contents. The application of the IS char as a biofertilizer for rye-grass growth studies under controlled conditions showed promising results in terms of leaf dimensions and mass yields of the plant. These preliminary results indicated the validity of the established strategy to convert OMW from a pollutant to green fuels, agricultural water source, and biofertilizer.

Vol. 134, pp. 10-23 
article DOI  
Abstract: The goal of the present research is to study the effect of the inorganic species on the pyrolysis mechanism of lignocellulosic biomass. Many contradictions as the catalytic role of inorganic salts characterize the research works published up to now. These ambiguities are reasonably due to the morphological and structural modifications of the reacting biomass by the various demineralization and impregnation methods, that impact on the pyrolysis mechanism. In order to clarify the effect of inorganics on the pyrolysis mechanism, alkali and alkaline earth (AAEM) containing salts were deposited by impregnation method on cypress sawdust. Nuclear magnetic resonance analyses showed that the biomass structure was preserved and that metal deposition passes through a cationic exchange mechanism. The thermogravimetric analyses show that AAEMs have different effects by influencing the degradation behavior and the mass balances. In particular, potassium and sodium elements accelerated the hemicellulose thermal degradation without modifying the reaction mechanism. In addition, they showed a catalytic effect in the cellulose degradation towards low weight molecules decomposition and condensation reactions leading to the increase of the char yield. Contrary, the presence of magnesium and calcium seems to inhibit the hemicellulose thermal degradation without a significant effect on the cellulose degradation mechanism. (C) 2017 Elsevier Ltd.

Vol. 57Polymer Testing, pp. 94-100 
article DOI URL 
Abstract: This work proposes a simple method for improving the rubber to filler stress transfer in short pineapple leaf fiber-reinforced natural rubber (NR). This was achieved by replacing some of the non-polar NR by polar acrylonitrile butadiene rubber (NBR). The amount replaced was varied from 0% to 20% by weight. The mixing sequence was designed so that the fiber would be coated with polar NBR before being dispersed in the NR matrix. A comparison system in which the mixing was carried out in a single step was also examined. Despite the fact that the two rubbers are immiscible, it was found that significant improvement of the stress transfer in the low strain region can be obtained. The mixing sequence affected the mechanical properties of the resulting composites. It is concluded that frictional stress transfer between the immiscible rubbers contributes more to the total stress transfer than does the frictional stress transfer between non-polar NR and polar cellulose fiber. © 2016 Elsevier Ltd

Vol. 184, pp. 186-194 
article DOI  
Abstract: Aluminum/iron oxide/-hydroxide nanothermite compounds were prepared and investigated in detail. The fast and facile synthesis was undertaken via a coprecipitation route of iron precursor species (sulfate, chloride) in presence of aluminum nanoparticles with an average diameter of 100 nm, terminated by an amorphous Al2O3 passivation layer. The only difference during synthesis is temperature, leading to a non-magnetic (at 20 degrees C) and magnetic (at 50 degrees C) nanothermite. HR-TEM and XRPD analysis reveal a predominantly amorphous iron oxide/-hydroxide nanoscaled matrix surrounding the aluminum nanoparticles. Moreover, aluminum nanoparticles and nanoscaled iron oxide/-hydroxide build up a hierarchical Al/Al2O3/FexOyHz, core/shell/shell structure in the case of the magnetic nanothermite. The non-magnetic nanothermite system lacks this significant structure. Finally, as-synthesized systems highly differ in reactivity, which is explained by their individual structural discrepancies. Values of flame propagation velocities and distinct threshold values of sensitivity to electrostatic discharge align with comparable reported aluminum/iron oxide aero- and xerogels in the literature.

Hureau, M., Moissette, A., Tzanis, L. and Daou, J. Effects of the zeolite particle size on the charge separated states 2017 Microporous and Mesoporous Materials
Vol. 254, pp. 121-127 
article DOI  
Abstract: Electron transfers occurring after sorption and photoexcitation of p-terphenyl molecules in the porous void of two MFI type zeolites were investigated. The influence of the morphology and particle size, i.e.; nanosheets and conventional coffin-shaped micron sized crystals (big crystals) on these phenomena were emphasized. The irradiation of PTP occluded in big crystals induces the formation of a radical cation which evolves to an "electron-hole pair through the capture of another electron of zeolite. In contrast, if photoexcitation of PIP incorporated in nanosheets induces also radical cation, it is interesting to note that the electron-hole pair formation is not favored in such environment. The absence of charge compartmentalization within nanosheets is put forward to explain the inhibition of electron transfer to create the charge transfer complex. Indeed, the small thickness of nanosheets prevents electron hopping over long distance after ionization and consequently, as the electron is trapped nearby the radical cation, direct recombination is favored.

Abstract: Low-cost tubular macroporous supports for ceramic membranes were elaborated using the extrusion method, followed by curing, debinding, and sintering processes, from a powder mixture containing kaolin, starch, and sand. The obtained substrates were characterized using mercury intrusion porosimetry, water absorption test, water permeability, scanning electron microscopy, and three-point bending test to evaluate the effects of the additives on the relevant characteristics. According to experimental results, adding the starch ratio to the kaolin powder shows a notable impact on the membrane porosity and consequently on the water permeability of the tubular supports, whereas their mechanical strength decreased compared to those prepared from kaolin alone. It has been shown that the addition of an appropriate amount of starch to the ceramic paste leads to obtaining membrane supports with the desired porosity. Indeed, the water permeability increased significantly from 20 to 612 L h−1 m−2 bar−1 for samples without and with 20 wt% of starch, respectively, as well as the open porosity, the apparent porosity, and the pore size distribution. The bending strength decreased slightly and reached about 4 MPa for samples with the highest starch amounts. On the other hand, the incorporation of sand in a mixture of kaolin + 10 wt% starch increased the mechanical strength and the water permeability. The samples containing 3 wt% of sand exhibited a bending strength four times higher than the supports without sand; the water permeability measured was about 221 L h−1 m−2 bar−1. These elaborated tubular supports for membrane are found to be suitable for solution concentration; they were applied for algal solution and are also easily cleaned by water. © 2017 Springer-Verlag Berlin Heidelberg

Vol. 277, pp. 95-126 
article DOI URL 
Abstract: We report on the banded polymer morphology of several semicrystalline commodity polymers such as high-density poly(ethylene), poly(trimethylene terephthalate), poly(vinylidene fluoride), and poly(3-hydroxybutyrate). The internal structural organization and 3D shape of the constitutive crystalline lamellae have been topics of interest in polymer physics for the last 50 years. However, conventional morphological characterization techniques (electron and/or optical microscopy) can be misleading in such analyses and have resulted in wrong interpretations of the twisted lamella growth mechanisms. We present nanofocus synchrotron X-ray scattering experiments and describe the analysis used to interpret the arrays of nanodiffractograms acquired along the spherulitic radii. It is shown that the crystal twist occurring during radial outward growth is regular and uniform. The 3D lamella shape is in most cases similar to the classic helicoid, whereas in other cases, such as the lamellae of poly(propylene adipate), it corresponds to a spiral structure. Access to comprehensive microstructural information about bulk samples makes it possible to better understand the twisted growth mechanisms and check the premises of the Keith and Padden model linking the direction of chain tilt and lamella twist hand. It is demonstrated that this model cannot explain the banding behavior in poly(trimethylene terephthalate) and therefore needs reconsideration. In-depth analysis of the microstructure allows more general conclusions to be drawn regarding correlation of chiralities pertinent to different spatial scales, ranging from that of the constitutive monomer to the supramolecular level of twisted lamellae. © Springer International Publishing Switzerland 2016.

Vol. 41(8), pp. 1134-1149 
article DOI  
Abstract: The water vapor sorption capacity and corresponding generated heat amount are the most important properties for adsorbents in thermochemical heat storage systems. In order to understand the adsorption/desorption behavior of three nanoporous molecular sieves such as 5A, mordenite and natural clinoptilolite (with different structures, Si/Al ratios and balancing cations), the pure zeolites and their composites (obtained by depositing NaOH onto the molecular sieves) were characterized in their structural and surface properties by using appropriate techniques (N-2 adsorption isotherms at -196 degrees C, XRD and (MAS) NMR). The adsorption of water was performed using a Setaram TG-DSC 111 apparatus. Three successive cycles of hydration (at 20 degrees C)/dehydration (at 150 degrees C) were carried out to check the stability of the system in conditions close to those used in adsorption heat pumps. The measured heats of dehydration vary in the 183-614kJkg(sample)(-1) range for the various samples that present also different water vapor sorption capacities (from approximate to 0.08 to approximate to 0.14 kg(H2O) kg(sample)(-1)). The water adsorption/desorption behavior of the zeolites was mainly related to the porous structure and to the Si/Al ratio, that drive the affinity of zeolite to water. The experimental results showed that the impregnation of the three kinds of nanoporous zeolites with different amounts of sodium hydroxide negatively affects the sorption characteristics of the composites. The blockage of zeolite pores (that limits the access to water molecules), the slight amorphization of the zeolite structure and the formation of carbonates are some of the phenomena identified to influence the water sorption onto NaOH-containing composites.

Vol. 172, pp. 177-185 
article DOI  
Abstract: The purpose of this paper is to enhance the heat storage and mass transfer performances of mesoporous materials by adding a hygroscopic salt. Silica-gel, alumina, and bentonite were chosen as supports of 15 wt% of calcium chloride. Comparison between the three series of composites was done by analyzing the impact of the salt addition on the physico-chemical and sorption properties of the three host matrixes. Moreover, the water sorption/desorption kinetics on the different composites under operating conditions, close to those of heat pump application, has been studied. The thermal behavior of the composite materials was examined by TG/DSC analysis. The addition of calcium chloride increased the quantity of sorbed water and released heat. The composite silica gel/CaCl2 showed the highest sorption capacity (0.27 g(H2O) gsample(-1)) accompanied with the highest heat storage (746 J &ample 1). The activation energy determined for the desorption process was following the silicagel/CaCl2 < bentonite/CaCl2 < alumina/CaCl2 order, opposite to the pore size of the various composites, that was the larger for silica-gel based materials. Finally, the experimental results of rehydration were fitted with kinetics model in order to describe the kinetics of water vapor adsorption of the three mesoporous composites. Moreover, using the experimental data of rehydration a kinetic model was applied to describe water vapor diffusion in the three mesoporous composites.

The relationship between mineral contents, particle matter and bottom ash distribution during pellet combustion: molar balance and chemometric analysis 2017 Environmental Science and Pollution Research
Vol. 24(11), pp. 9927-9939 
article DOI  
Abstract: This paper aims to identify the correlation between the mineral contents in agropellets and particle matter and bottom ash characteristics during combustion in domestic boilers. Four agrifood residues with higher mineral contents, namely grape marc (GM), tomato waste (TW), exhausted olive mill solid waste (EOMSW) and olive mill wastewater (OMWW), were selected. Then, seven different pellets were produced from pure residues or their mixture and blending with sawdust. The physico-chemical properties of the produced pellets were analysed using different analytical techniques, and a particular attention was paid to their mineral contents. Combustion tests were performed in 12-kW domestic boiler. The particle matter (PM) emission was characterised through the particle number and mass quantification for different particle size. The bottom ash composition and size distribution were also characterised. Molar balance and chemometric analyses were performed to identify the correlation between the mineral contents and PM and bottom ash characteristics. The performed analyses indicate that K, Na, S and Cl are released partially or completely during combustion tests. In contrast, Ca, Mg, Si, P, Al, Fe and Mn are retained in the bottom ash. The chemometric analyses indicate that, in addition to the operating conditions and the pellet ash contents, K and Si concentrations have a significant effect on the PM emissions as well as on the agglomeration of bottom ash.

Vol. 10(9), pp. 1423 
article DOI  
Abstract: Olive Mill Wastewater (OMWW) treatment is considered to be one of the main challenges that Mediterranean countries face. Although several procedures and technologies are mentioned in the literature, these techniques have several disadvantages or have been limited to laboratory pilot validation without posterior industrial projection. Recently, an advanced environmental friendly strategy for the recovery of OMWW was established involving the impregnation of OMWW on dry biomasses, drying of these impregnated samples, and finally green fuels and biochar production. This established strategy revealed that the drying step is crucial for the success of the entire recovery process. Hence, two impregnated samples were prepared through OMWW impregnation on sawdust (IS) and olive mill solid waste (ISW). The drying kinetics of OMWW and impregnated samples (IS and ISW) were examined in a convective dryer (air velocity range from 0.7-1.3 m/s and the temperature from 40-60 degrees C). The experimental results indicated that the drying of the impregnated samples occurred twice as fast as for the OMWW sample. Such behavior was attributed to the remaining thin layer of oil on the OMWW surface Furthermore, the Henderson and Pabis model showed the suitable fit of the drying curves with a determination coefficient R-2 above 0.97. The drying rates were extracted from the mathematical models and the drying process was analyzed. The coefficient of effective diffusivity varied between 2.8 and 11.7 x 10(-10) m(2)/s. In addition, the activation energy values ranged between 28.7 and 44.9 kJ/mol. These values were in the same range as those obtained during the drying of other agrifood byproducts. The final results could be very helpful to engineers aiming to improve and optimize the OMWW drying process.

Vol. 529, pp. 178-184 
article DOI  
Abstract: Due to increasing demand for natural cosmetics, research about Pickering-Ramsden emulsions stabilized with natural colloidal particles like clay minerals also increases. There are a lot of studies about colloidal stability of emulsions containing clay minerals, but only few about illite containing clays that are widely used in cosmetic products. The ability of natural and purified illitic clays to stabilize sunflower oil-in-water emulsions with oil/water mass ratio 40: 60 is investigated. Cosmetic products used in health care should be slightly acidic and as close as possible to skin's pH (4.5-5.5), but the presence of carbonates can cause alkaline media and irritate the skin. Therefore, one part of used clays was purified from carbonates. Pickering-Ramsden emulsions were prepared with clay concentration of 3 and 6 mass% at neutral (pH 7-8) and acidic (pH 5.5) environment. The stability of emulsions was compared by using two methods - sedimentation and centrifugation based on the measured amount of separated oil. Emulsions with 6 mass% clay samples were significantly more stable than with 3 mass% clays. The stability of emulsions was also improved by the use of purified illitic clays (after the removal of carbonates) and at acidic pH 5.5. The increase of emulsions' stability is attributed to the viscosity. The higher the viscosity, the less oil was separated.

Vol. 35(1-2), pp. 3-19 
article DOI  
Abstract: In this study, adsorption capacities of uremic toxins over Faujasite (HFAU) and Beta (HBEA) have been evaluated by varying the composition of solvent by using water, physiological, and sodium chloride solutions. HFAU was found to be more efficient in adsorption of these molecules. The adsorption results over HFAU were compared in various conditions to understand the adsorption mechanism. Thus, the adsorption mechanism was confirmed also by Fourier transform infrared and X-ray diffraction analysis, and it is found to be through the interaction of creatinine by hydrogen bonding on two types of sites on zeolites. Pseudo-second-order equation described well the adsorption kinetics data. Equilibrium isotherms were determined by Fowler-Guggenheim model. Finally, hydrophobic HFAU zeolite seems to be an efficient adsorbent; it is able to be easily regenerated under air, through retention of these initial adsorption properties.

Vol. 24(11), pp. 9951-9961 
article DOI  
Abstract: In this present work, the disposal of waste frying oil was explored. The experiment tests were performed under nitrogen (N-2) atmosphere at 5 degrees C/min heating rate from the ambient temperature to 500 degrees C. In these operating conditions, the obtained pyrolitic liquid fraction was 76 wt% formed by 63.87 wt% of crude bio-oil and 12.13 wt% of aqueous fraction. The chemical characterization using FTIR, GC, and GC/MS has revealed that the bio-oil is a complex chemical mixture of linear saturated, unsaturated, and cyclic hydrocarbons and oxygenated compounds such as carboxylic acids, ketones, aldehydes, and alcohols. Moreover, the produced bio-oil can be considered as promising fuel with high calorific value (similar to 39 MJ/kg). However, the higher acidity (similar to 125 mg KOH/g sample) and viscosity (9.53 cSt at 40 degrees C) limit currently its direct use in engines. Therefore, although several promising results, further investigations are requested to improve the bio-oil quality in order to find an environmentally friendly issue to waste frying oil.

Vol. 24(11), pp. 9993-10004 
article DOI  
Abstract: A chemical-activated carbon (CAC) was prepared by phosphoric acid activation of olive stone. The CAC was characterized using various analytical techniques and evaluated for the removal of amoxicillin from aqueous solutions under different operating conditions (initial concentration, 12.5-100 mg L-1, temperature, 20-25 degrees C, contact time, 07000 min). The CAC characterization indicates that it is a microporous carbon with a specific surface area of 1174 m(2)/g and a pore volume of 0.46 cm(3)/g and contains essentially acidic functional groups. The adsorption tests indicated that 93 % of amoxicillin was removed at 20 degrees C for 25 mg L-1 initial concentration. Moreover, it was found that adsorption capacity increased with contact time and temperature. Kinetic study shows that the highest correlation was obtained for the pseudo-second-order kinetic model, which confirms that the process of adsorption of amoxicillin is mainly chemisorption. Using the intraparticle diffusion model, the mechanism of the adsorption process was determined. The equilibrium data analysis showed that the Sips and Langmuir models fitted well the experimental data with maximal adsorption capacities of 67.7 and 57 mg/g, respectively, at 25 degrees C. The chemical-activated carbon of olive stones could be considered as an efficient adsorbent for amoxicillin removal from aqueous solutions.

Abstract: Controlling the interactions of functional nanostructures with water and biological media represents high challenges in the field of bioimaging applicationS. Large contrast at low doses, high colloidal stability in physiological conditions, the absence of cell cytotoxicity, and efficient cell internalization represent strong additional needs. To achieve such requirements, we report on high-payload magnetofluorescent architectures made of a shell of superparamagnetic iron oxide nanoparticles tightly anchored around fluorescent organic nanoparticles. Their external coating is simply modulated using anionic polyelectrolytes in a final step to provide efficient magnetic resonance imaging (MRI) and fluorescence imaging of live cells. Various structures of PEGylated polyelectrolytes have been synthesized and investigated, differing from their iron oxide complexing units (carboxylic vs phosphonic acid), their structure (block-or tomblike), their hydrophobicity; and their fabrication process [conventional:or reversible addition fragmentation chain transfer (RAFT)-controlled radical polymerization] while keeping the central magnetofluorescent platforms the same. Combined photophysical, magnetic, NMRD, and structural investigations proved the superiority of RAFT polymer coatings containing carboxylate units and a hydrophobic tail to impart the magnetic nanoassemblies (NAs) with enhanced-MRI negative contrast, characterized by a high r(2)/r(1) ratio and a transverse relaxation r(2) equal to 21 and 125 s(-1) mmol(-1) L, respectively, at 60 MHz clinical frequency (similar to 1.5 T). Thanks to their dual Modality, cell internalization of the NAs in mesothelioma cancer cells could be evidenced by both confocal fluorescence microscopy and magnetophoresis. A 72 h follow-up showed efficient uptake after 24 h with no notable cell mortality. These studies again pointed out the distinct behavior of RAFT polyelectrolyte-coated bimodal NAs that internalize at a slower rate with no adverse cytotMdcity. Extension to multicellular tumor cell spheroids that mimic solid tumors revealed the successful internalization of the NAs in the periphery cells, which provides efficient deep-imaging labels thanks to their induced T-2* contrast, large emission Stokes shift, and bright dotlike signal, popping out of the strong spheroid autofluorescence.

Abstract: The development of green, sustainable and simple synthetic pathways for the design of polymer and carbonaceous materials with well controlled features is of great importance in various fields of applications. Herein, we report a green synthetic method for polymer and carbon particles with well-defined shapes and sizes. This approach involves the use of green precursors, water as the solvent, and no templates under ambient temperature and pressure conditions, simultaneously. Green polymer resins (phloroglucinol-glyoxylic acid) and a catalyst/nitrogen source (triethylenediamine) are dissolved in water at room temperature resulting in polymer particles, which by subsequent thermal treatment transform into carbon particles. Mainly spherical carbon particles with controlled sizes from 500 nm to 10 mu m are obtained by simply adjusting the experimental conditions, i.e., the synthesis time and molar ratio between the precursors or solvent. In some conditions, a flower-like morphology is obtained as well. The synthetic mechanism for the formation of the polymer resin spheres up to their conversion into carbon spheres is proposed based on several techniques, i.e., C-13 NMR spectroscopy, SEM, XPS and TPD-MS (temperature programmed desorption coupled with mass spectrometry).

Vol. 19(8), pp. 270 
article DOI  
Abstract: Comprehensive understanding of the hydrogen gas interaction with metal nanoparticles is crucial for the development of multifunctional materials. The hydrogen absorption properties of well-dispersed Pd-Ir nanoalloys on a mesoporous carbon are reported here. The average size of nanoalloys depends on the composition and is comprised between 2.7 and 3.5 nm with decreasing Ir content. Structural analysis evidences a single phase FCC structure for all nanoparticles and a linear variation of the lattice parameter with composition confirming the formation of nanoalloys in this bulk-immiscible system. The hydrogen absorption properties can be tuned by the chemical composition: Pd-rich nanoparticles form hydride phases, whereas Ir-rich phases do not absorb hydrogen under ambient temperature and pressure conditions. The thermodynamic properties of hydride formation in Pd-rich phases are altered relative to the bulk counterparts. Moreover, the hydrogen absorption capacity in Pd-rich nanoalloys is larger as compared to bulk alloys. This might be explained by an important finite size effect that increases the hydrogen absorption capability of Pd-Ir alloys at nanoscale.

Abstract: Topographical and chemical features of biomaterial surfaces affect the cell physiology at the interface and are promising tools for the improvement of implants. The dominance of the surface topography on cell behavior is often accentuated. Striated surfaces induce an alignment of cells and their intracellular adhesion-mediated components. Recently, it could be demonstrated that a chemical modification via plasma polymerized allylamine was not only able to boost osteoblast cell adhesion and spreading but also override the cell alignment on stochastically machined titanium. In order to discern what kind of chemical surface modifications let the cell forget the underlying surface structure, we used an approach on geometric microgrooves produced by deep reactive ion etching (DRIE). In this study, we systematically investigated the surface modification by (i) methyl-, carboxyl-, and amino functionalization created via plasma polymerization processes, (ii) coating with the extracellular matrix protein collagen-I or immobilization of the integrin adhesion peptide sequence Arg-Gly-Asp (RGD), and (iii) treatment with an atmospheric pressure plasma jet operating with argon/oxygen gas (Ar/O-2). Interestingly, only the amino functionalization, which presented positive charges at the surface, was able to chemically disguise the microgrooves and therefore to interrupt the microtopography induced contact guidance of the osteoblastic cells MG-63. However, the RGD peptide coating revealed enhanced cell spreading as well, with fine, actin-containing protrusions. The Ar/O-2-functionalization demonstrated the best topography handling, e.g. cells closely attached even to features such as the sidewalls of the groove steps. In the end, the amino functionalization is unique in abrogating the cell contact guidance

Vol. 8(36), pp. 5580-5592 
article DOI  
Abstract: The goal of this paper concerns the development of photoinitiating systems usable in industrial processes for coating applications (cationic polymerization of epoxide based resins), the manufacture of Interpenetrating Polymer Networks (IPNs) (polymerization of acrylate/epoxy blends) and the production of thick epoxy/glass fibre composites. For these purposes, a copper photoredox catalyst, G1, is proposed as a high performance photoinitiator. It allows the design of very efficient three component photoinitiating systems (G1/iodonium salt (Iod)/N-vinylcarbazole (NVK)). The effects of the resin, light source (LED@ 375, 395, 405 nm, halogen lamp), G1 concentration, coating thickness (25 mu m and 1.4 mm), water content, formulation stability and hydrolytic stability of the cured coatings were investigated. Examples of IPNs and glass fibre composites are provided. In the studied applications the G1/Iod/NVK system is much better than BAPO/Iod/NVK (BAPO -bis(2,4,6-trimethylbenzoyl) phenylphosphine oxide -Irgacure 819) used as a reference system with good reactivity in the 365-420 nm range. Owing to the catalytic nature of G1, a reduced G1 content (30 fold less compared to the BAPO content) still leads to a higher practical efficiency than BAPO in the photopolymerization of a coating. A comparison with other reference systems based on 2-isopropylthioxanthone or anthracene is also provided and outlines again the very high performance of G1 for industrial applications.

Vol. 5(2), pp. 1906-1916 
article DOI  
Abstract: The present study has revealed that torrefied coffee grounds (CG) derived from agriculture commodities can be used as bioreinforcing agent for biodegradable poly(butylene adipate-coterephthalate) (PBAT) without requiring a compatibilizer. The optimum torrefaction operation was achieved in order to increase the hydrophobicity of CG. The raw CG was also used as a reference to assess the effect of the torrefaction operation. The structure and morphology of the composites were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The effect of the addition of raw or torrefied CG on the melting temperature and crystallinity of PBAT biocomposites was analyzed by differential scanning calorimetry (DSC). A significant enhancement in the thermo-mechanical properties for PBAT/torrefied CG composites was observed compared to PBAT/CG composites. Moreover, the hydrophobicity of PBAT composites which was determined by water contact angle was improved when torrefied biomass was added. The thermal stability of the investigated samples was analyzed by thermogravimetric analysis (TGA) and a kinetic model was proposed to describe the thermal degradation of raw CG, torrefied CG, PBAT, and their filled composites. The obtained results for these solvent-free prepared biocomposites show that they can be potential candidates for food packaging applications.

Abstract: Layered montmorillonite was synthesized by hydrothermal method, progressively modified by an alkylammoniumand thoroughly characterized by elemental, thermal, and X-ray diffraction (XRD) analysis. Pristine and modified clayswere introduced inmaleic anhydride-modified ethylene- co-propylene-co-diene monomer matrix. XRD and transmission electron microscopy investigations showed microcomposite as well as intercalated or exfoliated nanocomposites morphologies depending on the organic content of the clay. The inhibitor character of the pristine clay on peroxides as crosslinking agent for rubbers was then demonstrated and overcome by using electron beam irradiation for specimens containing unmodified clay. Dynamic mechanical analyses and swelling measurements showed that it is possible to obtain the same degree of crosslinking of the polymer matrix by electron beam irradiation of the composites based on pristine clay specimens and conventional peroxide curing of modified-clay-based ones. Finally, flame-retardant properties of different clays-based composites showed a direct dependence on the degree of exfoliation. It was observed that the better the exfoliation, the higher is the flame retardancy. (C) 2015 Society of Plastics Engineers

Abstract: The one pot synthesis of dual mesoporous titania (2.3 and 7.7 nm) has been achieved from a mixture of fluorinated and Pluronic surfactants. The small and large mesopore networks are templated, respectively, by a fluorinated -rich liquid crystal and a Pluronic-rich liquid crystal, which are in equilibrium. After calcination at 350 degrees C, the amorphous walls are transformed into semicrystalline anatase preserving the mesoporous structure. Results concerning the photodegradation of methyl orange using the calcined photocatalysts highlight that the kinetic rate constant (k) determined for the dual mesoporous titania is 2.6 times higher than the k value obtained for the monomodal ones.

Abstract: Using dual mesoporous titania as a support, due to the presence of intrinsic Bronsted acid sites, the main approach to 4,6-dimethylbenzo-thiophene (46DMDBT) hydrodesulfurization (HDS) becomes the direct desulfurization (DDS) route through isomerization and dismutation reactions, instead of the hydrogenation (HYD) pathway usually observed with a conventional promoted (by Ni or Co) MoS2/Al2O3 catalyst.

Vol. 879, pp. 78-83 
article DOI URL 
Abstract: A crucial factor for ingrowth of permanent implants in the bone is the rapid cellular acceptance. The topographical features often follow mechanical aspects for implant stability. But several of these implants fail due to insufficient cell adhesion. Cells are able to perceive the physicochemical properties of their surrounding and to pass these signals into the cell to modulatetheir adhesion structures, growth or production of extracellular matrix. However, the complex cell physiology at the material interface is not yet fully understood, particular on stochastically structured topographies resulting from industrial production. We could find out that corundum blasted titanium hampered the organization of actin filaments inside the cells, clustered adhesion components, e. g. beta-1 integrins and tensin, and the cells bridged the valleys which reduces cellsubstrate contacts. These morphological changes strongly diminished the mineralization of osteoblasts. To shed light on cause and effect we reduced the physical complexity of the material surface by introduction of regular micro-structures (pillars, grooves) using deep reactive ion etching. Now it was more obvious what cells are doing on sharp edged topographies - the actin filaments of our cells were clustered around the pillars. As a result the intracellular calcium signaling and the protein synthesis were impaired. Our recent findings indicated an attempted phagocytosis of the micro-pillars by osteoblasts. Therefore we conclude that implants used in orthopedic surgery should avoid any sharp-edged topographical features that could induce phagocytosis by the surrounding cells, which is an unnecessarily energy consuming process. © 2017 Trans Tech Publications, Switzerland.

Abstract: Symmetric alpha,omega-bis-silylated precursors are the standard building blocks of self-assembled bridged silsesquioxanes, a unique class of robust ordered nanomaterials prepared by sol-gel process without external surfactant. We report an unprecedented approach based on the utilization of a dissymmetric bis-silylated precursor, 1,2-bis(trimethoxysilyl)decane (1), in which the two alkoxy groups are carried by adjacent methylene groups. Extensive characterization-based on X-ray diffraction, real-time fourier transform infrared, electron and optical microscopy, Si-29 solid-state nuclear magnetic resonance, thermogravimetry, and molecular modeling-shows surprisingly that such non-symmetrical precursor is highly conducive to achieve highly ordered lamellar mesostructure, able to sustain temperature up to 120 A degrees C. To emphasize the effect of the alkoxy group functionality and position, comparison is made systematically with analogous silsesquioxanes derived from bis-(2) and mono-silylated (3) precursors. The sol-gel polymerization of 1 is unique by its ability to produce a homogeneous film possessing structural characteristic on multiple scales: uniform microcrystallites consisting of nanolamellar organosilica hybrid material. The most likely mesostructure consists of bilayers of slightly interpenetrated trans C8H9 chains, with a single central siloxy-hydrocarbon chain (Si2O(OH)(4)-C2H3) (n) . To permit a good lateral chain packing, the hydrocarbon chain of two adjacent silicon atoms point in opposite directions.

Vol. 23(2-3), pp. 395-403 
article DOI  
Abstract: FAU-*BEA-types zeolites pellets were elaborated with a hydraulic press in the presence of a small amount (5 wt%) of binder [methylcellulose (MC) or anhydrous sodium metasilicate (Na2SiO3)] for molecular decontamination, in particular for the space field. Nitrogen sorption-desorption revealed a small loss of micropore volume (10%) with a compression load of 6 tons (0.24 cm(3)/g instead of 0.27 cm(3)/g for the mixture of FAU and *BEA-types zeolites powders), which can be attributed to a partial amorphization. Adsorption kinetics of n-hexane, and cyclohexane showed that the optimum pellets can adsorb volatile organic compounds. For example, FAU-*BEA-type zeolite powder mixture (50 wt% of each zeolite) adsorb 130 mg of n-hexane per g of anhydrous zeolite whereas the pellets made with 5 wt% of MC or Na2SiO3 adsorb about 117-118 mg of n-hexane per g of anhydrous zeolite. These results are coherent with the ones obtained with the cyclohexane and nitrogen adsorption where a small loss of the adsorption capacities was observed.

Vol. 41(7), pp. 2586-2592 
article DOI  
Abstract: In order to study the energetic performances of different "pure silica chabazite-LiCl aqueous solution" systems, intrusion-extrusion experiments were performed under high pressure. Depending on the LiCl concentration in the aqueous medium (0 M, 5 M, 10 M, 20 M), an increase of the stored (4.4, 9.9, 13.5, 24.3 J g(-1)) and restored (2.6, 8.1, 11.8, 20.5 J g(-1)) energies are observed. Therefore, compared to the "pure silica CHA-H2O" system, the stored energy is increased by 5.5 times for the "pure silica CHA-20 M LiCl" one. The zeolite samples were characterized (XRD, TG, NMR spectroscopy, N-2 adsorption and SEM) before and after the intrusion-extrusion process in order to better understand the influence of the LiCl concentration on the system behavior.

Abstract: The energetic performances of the pure silica BEC-type zeolite are determined by high pressure intrusion-extrusion experiments with water and 20 M LiCl electrolyte aqueous solution. BEC-type zeosil displays a bumper behavior with water and a shock absorber with 20 M LiCI aqueous solution. The characterization of the sample before and after intrusion-extrusion experiments shows clearly that the BEC structure is more affected in the presence of water than with the 20 M LiCl solution.

Abstract: In our recent article entitled "re-exploring the double-melting behavior of semirigid-chain polymers with an in-situ combination of synchrotron nanofocus X-ray scattering and nanocalorimetry" (European Polymer Journal 81 (2016) 598-606), we investigated complex thermal behavior of a typical semirigid-chain polymer, poly(trimethylene terephthalate), PTT. In the comment on our paper published by Furushima and colleagues (EUROPOL_2017_495), our interpretation of the multiple melting phenomenon was seriously questioned. In particular, it was argued that the main drawback in our paper was due to the fact that the critical heating rate above which the PTT structure does not reorganize after isothermal melt crystallization at 180 degrees C should be 2000 C.s(-1), i.e. higher than the rate of 1000 degrees C.s(-1) used in our experiments. It is noteworthy that the authors of the Comment performed all their experiments on a different grade of PIT, which makes quantitative comparison with the recrystallization rates in our experiments problematic. In the present paper, we employ a combination of X-ray scattering with fast single photon-counting X-ray detection and custom-built ultrafast chip calorimeter to show that the claims of Furushima and colleagues are not relevant to our case and, therefore, cannot be generalized. Indeed, even for a PIT sample melt-crystallized at 150 degrees C, which recrystallizes on heating much faster than the sample crystallized at 180 degrees C, the critical heating rate is safely below 500 degrees C.s(-1). To further clarify the issue, we discuss on a general misconception in the literature concerning the interpretation of double melting peaks in DSC traces as being indicative of a melting/recrystallization process. Since many works in the field including the discussed one are based entirely on calorimetric data, the direct information on the structure is simply missing. Therefore, such interpretations of the thermal behavior evoking the so-called "single crystal population" are clearly inadequate. By contrast, on the basis of on-time X-ray scattering recorded simultaneously with ultrafast chip calorimetry we unambiguously show that even in the absence of reorganization processes a uniform population of PTT crystals formed at isothermal conditions exhibits double melting. In agreement with our earlier publications (e.g., Macromolecules 41 (2008) 9224-9231) this is explained by strong interactions between amorphous and metastable crystalline regions, which are very characteristic for the semirigid-chain polymer family.

Abstract: This work describes the first transition metal-free stereospecific synthesis of (E)-(1-fluoro-2-arylvinyl)phosphine boranes through the addition of diarylphosphine-boranes to gem-bromofluoroalkenes in the presence of a base at room temperature. The reaction proceeds well under very mild conditions and tolerates a variety of functionalities. Scope and limitations of the reaction are discussed. Mechanistic investigations have been undertaken and revealed that the reaction takes place through an SRN1 mechanism. The formation of the fluorinated vinyl radical has been evidenced by electron paramagnetic resonance (EPR) experiment.

Eosin-mediated synthesis of polymer coatings combining photodynamic inactivation and antimicrobial properties 2017 Journal of Materials Chemistry B
Vol. 5(36), pp. 7572-7582 
article DOI  
Abstract: Polymer coatings exhibiting photodynamic bacterial inactivation properties have been successfully engineered. Such coatings were obtained by photoinduced crosslinking of a PEG-diacrylate monomer associated with the eosin Y dye which was used as both a radical photoinitiator and an antibacterial agent. A dual curing process was followed by combining compatible and solvent-free polymerization mechanisms, i.e. Aza-Michael reaction and free-radical polymerization in the presence of amines. The kinetics evolution of the photopolymerization process was followed using in situ Fourier transform infrared spectroscopy, allowing for the elucidation of the underlying mechanistic pathways. The influence of eosin Y and amines on the thermal and mechanical properties of the films was evidenced and discussed in terms of crosslinking chemistry. The antibacterial properties of the coatings against two different strains (Escherichia coli and Staphylococcus aureus) were evaluated on short and long terms, revealing that eosin confers both photodynamic inactivation and antimicrobial properties to the films. These coatings are therefore particularly promising for disposable medical devices.

Sauvage, J.B., Aufray, M., Jeandrau, J.P., Chalandon, P., Poquillon, D. and Nardin, M. Using the 3-point bending method to study failure initiation in epoxide-aluminum joints 2017 International Journal of Adhesion and Adhesives
Vol. 75, pp. 181-189 
article DOI  
Abstract: The increasing use of adhesives in industry has boosted the search for tests which allow the adherence level to be defined. These tests, depending on the type of load, examine different stresses, failure modes and mixed modes. Furthermore, these tests can be focused either on initiation or propagation of adhesive failure. The subject of this study is the initiation of adhesive failure. The initiation of failure can be determined with the 3-point bending test. Trials of 3-point bending tests were conducted on an aluminum 2024 substrate, with two different thicknesses, in order to understand the impact of the adherend thickness. The aluminum substrate received different types of surface pre-treatment: acetone cleaning, hydrochloric acid etching or aminopropyltriethoxysilane coating. Two adhesives were used: the first one was a mixture of epoxy pre-polymer DGEBA and DETA amine, whereas the second was a commercially formulated adhesive, ELECOLIT 6604. The initiation of adhesive failure was obtained by 3-point bending test and verified with SEM analysis. The failure loads measured enabled the effect of surface treatment on adhesive failure to be revealed: the results indicate that the surface treatment with silane is the most efficient in comparison to hydrochloric add etching and of course to the simple acetone degreasing. It was assumed that the scatter of the results obtained for each series is due to the variation of the "intrinsic" adherence between the adhesive and the substrate. Furthermore, it was noted that the failure loads for different substrate thicknesses cannot be compared due to the effect of the thickness: it was therefore not possible to simply compare results obtained for different thicknesses of the same substrate for a given substrate-adhesive system. The energy approach proposed in this study makes it possible. The energy requested to initiate the adhesive failure for a given system can then be known, whatever the initial geometry of the 3-point bending test is. However, it was also shown that the thickness of the substrate must be correctly chosen. A thick substrate increases the dispersion and a thin substrate may induce local unwelcome plastic strain. In conclusion, this study allows to define an energy criteria for adhesives failure initiation.

Schmitt, M. and Lalevee, J. ZnO nanoparticles as polymerisation photo- initiator: Levulinic acid/NaOH content variation 2017 Colloids and Surfaces A-physicochemical and Engineering Aspects
Vol. 532, pp. European Colloid \& Interface Soc 
article DOI  
Abstract: Recently it was demonstrated that the well-known photo-semiconductor ZnO have the additional potential to be used as photo-initiator for the initiation of multifunctional acrylic esters in bulk. For such commercially used polymerization procedures like for food packaging or dental applications the migration and transport of molecular polymerization initiators are problematic. As analytically proven even newest commercial polymeric initiators results in possible health risks. Enlarging the size of the initiator as performed by using particles can be an alternative way to prevent contamination. In this manuscript, influences of the modification conditions using a non-chromophoric molecule on the curing potential of nanoscaled ZnO are analysed by recently developed UV-vis transmission curing measurements to demonstrate the concept of this alternative initiation system. A commercial acrylic resin containing only the modified photo semiconductor is taken as model systems for the UVcuring. An important aspect of this contribution is the brief and focused explanation of the photo-physical mechanisms for the application of bulk polymerisation which is supported by measurements of different modifications of the particles surface by organic acids or metal salts and their influences the charge transfer recombination which was monitored by fluorescence and which influence the curing potential.

Vol. 134(23) 
article DOI URL 
Abstract: The present study deals with the consolidation of an ultra-high performance polymer, the poly(ether ether ketone) (PEEK), for structural applications, using the powder metallurgy (PM) way, and more precisely the Spark Plasma Sintering (SPS) processing. The effects of SPS parameters such as temperature, pressure, and dwell time on density and mechanical properties of PEEK were investigated via a Design of Experiments (DoE). A temperature of 250 °C, a pressure of 40 MPa, and a dwell time of 20 min have been identified as the optimal SPS process parameters. In these conditions, a density of 1.31 g/cm3 was reached and homogeneous mechanical properties in the volume determined by means of compression tests were found with a compressive modulus of 2.75 GPa, a yield strength of 134 MPa, and a maximum compressive strain of 43%. These results are better than those of commercial products obtained by injection molding. The pressure appears to be a significant parameter on PEEK properties and plays positive or negative roles according to the responses of DoE studied. To our knowledge, it is one of the first studies based on the application of the PM techniques for PEEK consolidation showing the possibility to process below its melting point. © 2017 Wiley Periodicals, Inc.

Vol. 4(4), pp. 460-463 
article DOI  
Abstract: Microscopy techniques allowing observation of unlabeled samples have recently experienced a regain of interest. In particular, approaches based on recording of the optical field diffracted by the specimen, in amplitude and phase, have proven their capacities for biological investigations. When combined with variations of specimen illumination, tomographic acquisitions are possible. One limitation of previously developed approaches is the anisotropic resolution, characteristic of all transmission microscopes. In this context, an instrument, characterized by isotropic high-resolution 3D imaging capabilities, is still awaited. For the first time, to the best of our knowledge, we have developed tomographic diffractive microscopy combining specimen rotation and illumination rotation, which delivers images with (almost) isotropic resolution below 200 nm. The method is illustrated by observations of nanoscopic fiber tips, microcrystals and pollens, and should be helpful for characterizing freestanding natural (diatoms, spores, red or white blood cells, etc.) or artificial samples.

Synthesis and photostability of 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP) structural isomers and their trimethylsilyl derivatives 2017 Dyes and Pigments
Vol. 141, pp. 128-136 
article DOI  
Abstract: In this work, a versatile synthetic method for preparation of linear phenyloxazoles and their organo-silicon derivatives under mild conditions via a combination of van Leusen and direct C-H arylation reactions is reported. It was used for the synthesis of a novel trimethylsilyl (TMS) derivative of blue laser dye 1,4-bis(5-phenyloxazol-2-yl)benzene (POPOP) and its structural isomer 1,4-bis(2-phenyloxazol-5-yl) benzene (isoPOPOP) with and without TMS substituents. All of the compounds demonstrated high photoluminescence quantum yields and large molar extinction coefficients, which further increased for their TMS derivatives. Measurements of accelerated photodegradation of the dyes in diluted THE solutions revealed that POPOP-type compounds are twice more stable than their isoPOPOP-type isomers, independent of the presence or absence of TMS substituents. Cyclic voltammetry (CV) investigations revealed that POPOP-type dyes are more electrochemically stable as compared to their isoPOPOP-type isomers. Quantum chemical TD DFT calculations of the frontier energy levels of the dyes were in a good agreement with the experimental data obtained by CV. Single-crystal X-ray diffraction experiments revealed significant structural differences between crystal lattices of the dyes. Due to facile synthesis and excellent optical properties as well as high photo- and thermo- stability the novel luminescent dyes may find wide application in organic photonics. (C) 2017 Elsevier Ltd.

Abstract: A new germanene crystallographic structure is investigated by scanning tunnelling microscopy and density functional theory calculations. We found that germanene can crystallize in two stable but different structures when grown on Al(111) at the same temperature. These structures are evidenced in scanning tunnelling images by a honeycomb contrast and by a hexagonal contrast. These contrasts are relevant of a Ge network with one (hexagonal) or two (honeycomb) Ge atoms per unit cell shifted upward with respect to the other Ge atoms. These structures appear alternatively and can be turned on and off by a tip-induced process.

Vol. 24(11), pp. 10030-10040 
article DOI  
Abstract: Glycerol, considered as a waste feedstock resulting from biodiesel production, has receivedmuch attention in recent years due to its properties, which offer to recover energy. The aim of this study was to investigate the use of a thermal water vapor plasma forwaste (crude) glycerol conversion to synthesis gas, or syngas (H-2 + CO). In parallel of crude glycerol, a pure glycerol (99.5%) was used as a reference material in order to compare the concentrations of the formed product gas. A direct current (DC) arc plasma torch stabilized by amixture of argon/water vapor was utilized for the effective glycerol conversion to hydrogen-rich synthesis gas. It was found that after waste glycerol treatment, the main reaction products were gases with corresponding concentrations of H-2 50.7%, CO 23.53%, CO2 11.45%, and CH4 3.82%, and traces of C2H2 and C2H6, which concentrations were below 0.5%. The comparable concentrations of the formed gas products were obtained after pure glycerol conversion-H-2 46.4%, CO 26.25%, CO2 11.3%, and CH4 4.7%. The use of thermal water vapor plasma producing synthesis gas is an effective method to recover energy from both crude and pure glycerol. The performance of the glycerol conversion system was defined in terms of the produced gas yield, the carbon conversion efficiency, the cold gas efficiency, and the specific energy requirements.

Vol. 218(18), pp. 1700192 
article DOI  
Abstract: A series of 18 iridium complexes (Ir) have been prepared and studied. Their abilities to initiate both a ring-opening cationic polymerization (CP) using an Ir/iodonium salt couple and a free radical polymerization (FRP) in the presence of an Ir/amine/alkyl halide system under very soft irradiation (i.e., halogen lamp) or upon exposure to laser diodes @457 nm and @532 nm are investigated. Interestingly, these photoinitiating systems operate through an oxidative or a reductive photoredox catalytic cycle, respectively. Excellent polymerization profiles are obtained (reactive function conversions >70% for the CP of an epoxide and >60% for the FRP of low viscosity triacrylate). The photochemical mechanisms are studied by fluorescence, steady state photolysis, cyclic voltammetry, and electron spin resonance spin trapping experiments.

Vol. 252, pp. 188-196 
article DOI  
Abstract: Paracetamol (acetaminophen (ATP)) at toxic concentrations to human is successfully adsorbed onto MFI-type zeolite ZSM-5 (Si/Al = 30) stepwise under conditions approaching human serum composition. While the speed of adsorption in physiological serum at 37 degrees C is fast enough to be accomplished in a 4 h standard dialysis session, maximum adsorption levels at equilibrium concentration is reduced when the solution becomes more complex. In pure water, at the highest equilibrium concentrations, the adsorption is almost doubled. Thermogravimetric measurements confirm paracetamol adsorption inside the micropores. Rietveld-analysis on powder X-ray diffraction data proves that after adsorption, paracetamol is located at the intersection of the straight and zigzag channel of the ZSM-5 zeolite. H-1 MAS NMR experiments performed on ZSM-5 zeolite after paracetamol adsorption confirm the absence of interaction between paracetamol molecules and water molecules and/or between the paracetamol molecules themselves. In conclusion, elimination of paracetamol at toxic concentrations in human serum (by ultrafiltration of blood) is a smart way to eliminate selectively such a molecule by physisorption without further interference onto other biochemical equilibria.

Vol. 14(10), pp. e1600215 
article DOI  
Abstract: Macroscopic kinetics of DMAEMA and HEMA plasma polymerization have been investigated. Different regimes in the kinetics of growth have been identified and the resulting plasma polymer surfaces have been characterized by Infrared and X-ray photoelectron spectroscopies as well as by wettability analysis. Various hydrogel properties have been obtained leading to different surface mechanical properties. The values of Young's modulus estimated by AFM nanoindentation were found to be systematically high in the case of DMAEMA plasma polymerization (4-6MPa). However, in the case of HEMA plasma polymerization, the Young's modulus values could be tune to 1MPa up to 4.5MPa. This result was even more remarkable as chemical composition of the corresponding surfaces was quasi-identical.

Abstract: British 19th century painters such as J.M.W. Turner, commonly modified the properties of their paint by using gels called gumtions. These gels allowed them to easily tune the paint handling and drying properties. The fascinating properties of these gumtions were obtained by adding lead acetate to a ternary system based on mastic resin, linseed oil and turpentine. Herein, we report and investigate in depth the rheological properties of these gels as well as their structure at a molecular and supra-molecular scale.

Vol. 24(11), pp. 10041-10055 
article DOI  
Abstract: Recycling cotton waste derived from the textile industry was used as a low-cost precursor for the elaboration of an activated carbon (AC) through carbonization and zinc chloride chemical activation. The AC morphological, textural, and surface chemistry properties were determined using different analytical techniques including Fourier transform infrared, temperature programmed desorption-mass spectroscopy, nitrogen manometry and scanning electron microscopy. The results show that the AC was with a hollow fiber structure in an apparent diameter of about 6.5 mu m. These analyses indicate that the AC is microporous and present a uniform pore size distributed centered around 1 nm. The surface area and micro-pore volume were 292 m(2).g(-1) and 0.11 cm(3).g(-1), respectively. Several types of acidic and basic oxygenated surface groups were highlighted. The point of zero charge (pHPZC) of theca was 6.8. The AC performance was evaluated for the removal of Alizarin Red S (ARS) from aqueous solution. The maximum adsorption capacity was 74 mg.g(-1) obtained at 25 degrees C and pH = 3. Kinetics and equilibrium models were used to determine the interaction nature of the ARS with the AC. Statistical tools were used to select the suitable models. The pseudo-second order was found to be the most appropriate kinetic model. The application of two and three isotherm models shows that Langmuir-Freundlich (n = 0.84, K = 0.0014 L.mg(-1), and q = 250 mg.g(-1)) and Sips (n = 0.84, K = 0.003 L.mg(-1), and q = 232.6 mg.g(-1)) were the suitable models. The results demonstrated that cotton waste can be used in the textile industry as a low-cost precursor for the AC synthesis and the removal of anionic dye from textile wastewater.

Vol. 10(9), pp. 1321 
article DOI  
Abstract: Phenolic resin and waste cotton fiber were investigated as green precursors for the successful synthesis using a soft template approach of a composite carbon with carbon nanofibers embedded in a porous carbon network with ordered and periodically pore structure. The optimal composite carbon (PhR/NC-1), exhibited a specific surface area of 394 m(2).g(-1) with the existence of both microporosity and mesoporosity. PhR/NC-1 carbon was evaluated as an adsorbent of Alizarin Red S (ARS) dye in batch solution. Various operating conditions were examined and the maximum adsorption capacity of 104 mg.g(-1) was achieved under the following conditions, i.e., T = 25 degrees C, pH = 3, contact time = 1440 min. The adsorption and desorption heat was assessed by flow micro-calorimetry (FMC), and the presence of both exothermic and endothermic peaks with different intensity was evidenced, meaning a partially reversible nature of ARS adsorption. A pseudo-second-order model proved to be the most suitable kinetic model to describe the ARS adsorption according to the linear regression factor. In addition, the best isotherm equilibrium has been achieved with a Freundlich model. The results show that the eco-friendly composite carbon derived from green phenolic resin mixed with waste cotton fibers improves the removal of ARS dye from textile effluents.

Vol. 55(24), pp. 4037-4045 
article DOI  
Abstract: Novel thioxanthone (TX) derivatives are used as versatile photoinitiators upon visible light-emitting diode (LED; e.g., 405, 425, and 450 nm) exposure. The mechanisms for the photochemical generation of reactive species (i.e., cations and free radicals) produced from photoinitiating systems based on the photoinitiator and an iodonium salt, tris(trimethylsilyl)silane, or an amine, were studied by UV-vis spectroscopy, fluorescence, cyclic voltammetry, steady-state photolysis, and electron spin resonance spin-trapping techniques. The reactive species are particularly efficient for cationic, free radical, hybrid, and thiol-ene photopolymerizations upon LED exposure. The optimized photoinitiating systems exhibit higher efficiency than those of reference systems (i.e., isopropyl TX-based photoinitiating systems), especially in the visible range. According to their beneficial features, these photoinitiating systems have considerable potential in photocuring applications. (c) 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Abstract: A series of donor--acceptor-type sulfonium salt photoacid generators (PAGs) were designed and synthesized by systematically changing electron-donating groups, -conjugated systems, electron-withdrawing groups, and the number of branches through molecular engineering. These PAGs can effectively decompose under UV/Vis irradiation from a light-emitting diode (LED) light source because of the matching absorption and emitting spectra of the LEDs. The absorption and acid-generation properties of these sulfonium salts were elucidated by UV/Vis spectroscopy and so forth. Results indicated that the PAG performance benefited from the introduction of strong electron-donating groups, specific -conjugated structures, certain electron-withdrawing groups, or two-branched structures. Most sulfonium salts showed potential as photoinitiators under irradiation by a wide variety of UV and visible LEDs.

Vol. 218(20), pp. 1700314 
article DOI  
Abstract: Rubrene, a compound that exhibits green light absorption, interacts with an iodonium salt through its excited singlet state to generate cations and free radicals under a green laser line at 532 nm or a halogen lamp delivering a low light intensity of polychromatic visible light. The photochemical mechanisms are investigated by steady-state photolysis, fluorescence, electrochemistry, and electron spin resonance spin trapping techniques. The produced cations and free radicals initiate both the cationic photopolymerization of epoxides and the free radical photopolymerization of acrylates. Moreover, the addition of N-vinylcarbazole into the system enhances the photopolymerization efficiency. The Rubrene/amine/chlorotriazine photoinitiating system also exhibits a much higher photoinitiation ability for the free radical photopolymerization of acrylates.

Vol. 243, pp. 135-146 
article DOI  
Abstract: Sulfur-doped porous carbons were synthesized by two synthetic approaches, i.e. a direct one (soft-template) and an indirect one (hard-template). In the soft-template approach, a phenolic resin based on phloroglucinol or resorcinol and thiophene carboxaldehyde (TCA) was self-assembled with a triblock copolymer followed by carbonization in inert atmosphere. For the second method, zeolite beta was used as hard-template and infiltrated with carbon by chemical vapor deposition (CVD) process followed by H2S treatment. Mesoporous materials with uniform pore size and moderate apparent specific surface area (up to 635 m(2) g(-1)) were obtained by soft-template route. The hard-template route, coupled with H2S post-treatment, allowed to obtain highly microporous/mesoporous materials having high apparent surface area (1700-2500 m(2) g(-1)) and high total pore volume (1.25-1.95 cm(3) g(-1)). High temperature or amounts of TCA induce a decrease of the microporosity and apparent surface area while the mesoporosity varies distinctly depending on the synthesis method used. The sulfur content could be easily modified by the amount of thiophene carboxaldehyde for the soft-templating route (up to 10.9 wt % at 600 degrees C) or by the H2S heat-treatment temperature for the hard-templating method. In the latter case, with the increase of the temperature up to 900 degrees C, high S-content was reached (up to 14.4 wt %). The influence of the carbon porosity and surface functionality on the H-2 and CO2 adsorption was evaluated. Hard-templated carbons possessing well developed microporosity adsorb the highest amounts of H-2 and CO2. The sulfur and oxygen groups lead to improvement of the hydrogen adsorption capacity and have less significant effect on CO2 storage. (C) 2016 Elsevier Inc. All rights reserved.

Vol. 505, pp. 410-420 
article DOI  
Abstract: Pd-Au nanoalloys confined in mesoporous carbonaceous materials were synthesized by a rapid one-pot microwave assisted approach. Green polymer resins based on phloroglucinol/glyoxylic acid or glyoxal were co-assembled in the presence of a template and metallic salts followed by microwave treatment between 40 and 80 degrees C and subsequent thermal annealing, allowing simultaneous formation of mesoporous carbonaceous materials with in-situ confined Pd-Au nanoparticles. Several Pd-Au compositions were prepared (PdxAu100-x, where x = 90; 80; 70 and 50) and their impact on the alloy structure and particle size/distribution evaluated. For Pd90Au10, homogeneously dispersed nanoalloy particles (similar to 8 nm) are obtained in the carbonaceous framework. The increase in the Au content in the alloy gradually induces an increase in the particle size and agglomeration of the particles along with the formation of multiphased alloys, i.e., segregated Pd- and Au-rich nanoparticles. The particle agglomeration was avoided by decreasing the thermal annealing time. The homogeneity of the alloy structure was found to strongly depend by two parameters, the chelating/cross-linker agents and the microwave temperature, i.e., the chelating/cross-linker agents containing carboxylic groups and the higher temperatures inducing more heterogeneous structures. The hydrogen absorption in Pd90Au10 particles with different homogeneity degree was studied at room temperature up to 1 bar. Generally, hydrogen absorbs in Pd-rich nanoalloys forming a hydride phase whereas Au-rich phases do not absorb hydrogen under the present conditions. (C) 2017 Elsevier Inc. All rights reserved.

Vol. 28(10), pp. 105603

Abstract: This paper reports on a simple and environmentally friendly photochemical process capable of generating nano-layers (8-22 nm) of silver nanostructures directly onto glass surfaces. This approach opens the way to large-scale functionalized surfaces with plasmonic properties through a single light-induced processing. Thus, Ag nanostructures top-coated were obtained through photo-reduction, at room temperature, of a photosensitive formulation containing a metal precursor, free from extra toxic stabilizers or reducing agents. The reactive formulation was confined between two glass slides and exposed to a continuous near-UV source. In this way, stable silver nano-layers can be generated directly on the substrate with a very good control of the morphology of as-synthesized nanostructures that allows tailoring the optical properties of the coated layers. The position and width of the corresponding surface plasmon resonance bands can be adjusted over a broad spectral window. By extension, this low-cost and easy-to-apply process can also be used to coat ultra thin layers of metal nanostructures on a variety of substrates. The possibility of controlling of nanostructures shape should achieve valuable developments in many fields, as diverse as plasmonics, surface enhanced Raman scattering, nano-electronic circuitry, or medical devices.

Zaier, M., Vidal, L., Hajjar-Garreau, S. and Balan, L. Generating highly reflective and conductive metal layers through a light-assisted synthesis and assembling of silver nanoparticles in a polymer matrix 2017 Scientific Reports
Vol. 7, pp. 12410 
article DOI  
Abstract: The development of metalized surfaces exhibiting mirror properties and/or electric conductivity without heavy equipments and with low metal charge is a big challenge in view of many industrial applications. We report herein on the photo-assembling of silver nanoparticles (AgNPs) in a polymer matrix, carried out within minutes from an acrylate monomer and silver nitrate at room temperature, under air and without any solvents. The top surface of the material gets converted into a continuous silver thin film and a depthwise concentration gradient of AgNPs is created in the polymer, which images the absorption profile of the actinic UV light in the reactive formulation. This specific assembling of the silver@polymer coating induces excellent reflective and conductive properties. The conductance was observed to strongly increase with increasing the exposure from 3 to 30 min due to the formation of a more and more compact metal film. This coating strategy works with a variety of substrates (textile, paper, glass, wood, plastic and stainless steel). Moreover, on flexible surfaces such as textile, the flexibility was preserved. The possibility to use this kind of nanomaterial as a printing ink, with a much lower metal concentration (3 to 5 wt.%) than concurrent inks, was also demonstrated.

Understanding the correlation and balance between the miscibility and optoelectronic properties of polymer-fullerene solar cells 2017 Journal of Materials Chemistry A
Vol. 5(33), pp. 17570-17579 
article DOI  
Abstract: Organic photovoltaics is one of the most promising technologies for sustainable green energy supply. Because of their high electron affinity and superior electron-transporting ability, fullerene-based materials are deemed as very strong electron-accepting components in organic solar cells. However, the most widely used fullerene-based acceptors, such as phenyl-C61-butyric acid methyl ester, exhibit limited microstructural stability and unsatisfactory thermal stability owing to their insufficient compatibility with organic donors. Here, we in-depth investigate the carrier dynamics along with structural evolution and analyze the acceptor loadings in optimized bulk-heterojunction (BHJ) solar cells as a function of the polymer-fullerene miscibility. The polymer-fullerene miscibility has more influential effects than the crystallinity of single components on the optimized acceptor : donor ratio in polymer-fullerene solar cells. The findings demonstrated in this work suggest that the balance between the miscibility of BHJ composites and their optoelectronic properties has to be carefully considered for future development and optimization of OPV solar cells based on BHJ composites. Miscibility is proposed in addition to crystallinity as a further design criterion for long lived and efficient solar cells.

Abstract: After a long-term thermo-oxidative exposure, compared to the long-glass-fiber reinforced polyamide 6 composite containing halogen-antimony flame retardants (FR/LGFPA6), substitution of a certain content of flame retardants with organo-modified montmorillonite (OMMT) was found to positively affect the FR/LGFPA6 composite in some cases (i.e. flammability and thermal degradation kinetics). The aged OMMT/FR/LGFPA6 composite not only was less flammable but also behaved better in the formation of char residues. All the calculated apparent activation energy obtained by the methods of Friedman, Flynn-Wall-Ozawa and Coats-Redfern in a dynamic measurement showed an obvious increase for the OMMT/FR/LGFPA6 composite after aging, a theoretical evidence for its improved flame retardancy. © 2017 Elsevier B.V.

Abidi, N.b., Duplay, J., Errais, E., Jada, A. and Trabelsi-Ayadi, M. Discoloration of textile effluent by natural clay improved through the presence of dyeing additives 2016 Desalination and Water Treatment
Vol. 57(57), pp. 27954-27968 
article DOI URL 
Abstract: The aim of this work was to investigate the possible mechanisms of adsorption of anionic dyes from effluents onto natural clay, and particularly the influence on the adsorption of dyeing additives, released in the effluents with the dyes. Batch experiments with an anionic dye (RR120) at different conditions showed that the adsorption was enhanced at high ionic strength, low pH and in the presence of the additive such as CHT Catalase derived from enzymatic products. On the contrary, the presence of another additive, Duralkan (nitrogenated polycondensate, formaldehyde and metal free), had a negative effect. Experimental methods, such as Fourier transform infrared spectroscopy, electrophoretic mobility and streaming induced potential, allowed us to evidence that CHT Catalase when mixed with RR120 neutralizes the dye and decreases the repulsion between RR120 molecules and the clay negative surfaces, thus favouring adsorption. However, the additive Duralkan does not neutralize the dye, but interacts with the clay, thereby competing with the dye for the clay surface reactive sites, leading hence to adsorption reduction. The efficient discoloration of effluents by clay suggests that in overall, the negative effect of some additives on adsorption is overcome by the positive effect of others. Thus, crude clay may be a promising adsorbent to treat effluents containing dyes and chemical additives. © 2016 Balaban Desalination Publications. All rights reserved.

Vol. 101, pp. 309-316 
article DOI URL 
Abstract: Porous Mn-doped ZnO (ZnO:Mn) nanoparticles with an average diameter of ca. 21 nm were prepared by a simple and cheap solvothermal process involving no templates, post-synthetic annealing or etching. The particles produced were characterized by XRD, Raman spectroscopy, SEM, TEM, XPS, diffuse reflectance spectroscopy and BET surface area measurements and the effects of Mn2+-doping on the structural, optical and photocatalytic properties of ZnO particles were investigated. The particles doped with 3 mol% Mn2+ were found to exhibit the highest catalytic activity toward the photodegradation of the Orange II dye under solar light irradiation. Our results demonstrate that Mn2+-doping shifts the optical absorption to the visible region, increases the specific surface area of the photocatalyst and reduces the recombination of electron-hole pairs. The influence of various operational parameters (amount of catalyst, concentration of dye and pH) on the photodegradation and the photocatalytic mechanism were studied. Finally, we demonstrated that the ZnO:Mn photocatalyst is stable and can be easily recycled up to ten times without any significant decrease in photocatalytic activity. © 2016 Elsevier Ltd.

Abstract: The development of coating methods that enable us to combine antagonist properties on a single material is a real challenge. This active research topic can impact, for instance, the textile field to engineer fabrics with liquid-repellent properties on one side and superhydrophilic properties on the opposite side. In this context, we have developed an easy surface functionalization process that provides durable Janus wetting properties to fabrics. On the basis of plasma-enhanced chemical vapor deposition (PECVD), we report a simple and reproducible three-step functionalization method that led to a coating with superhydrophobic and superoleophobic properties on one side of the porous substrate and superhydrophilic properties on the opposite side. A thin, fluorinated polymer film was deposited on one side, while the other side was functionalized with a polymer coating made of maleic anhydride, subsequently hydrolyzed to provide carboxylic acid groups to the surface. Static contact angles up to 169° with water and 162° with hexadecane were obtained on the fluorinated side of the fabric thanks to an appropriate combination of surface chemistry with dual-scale surface roughness. In addition, roll-off angles of 6 and 14° with water and hexadecane, respectively, were measured on this side of the sample. As for the opposite side, the hydrolyzed plasma polymer made of maleic anhydride enables us to obtain a surface that fully absorbs water and hexadecane. In addition, these tremendous properties were durable because no significant change was observed after aging and washing cycles. This simple surface functionalization process based on plasma polymerization is an innovative solution for the fabrication of textile with durable waterproof and breathable properties. Besides, the described concept can be adapted to numerous other applications that require Janus properties to porous substrates.

Abstract: Nonwovens of polymer/clay composite nanofibers (namely, polyacrylonitrile/Na-montmorillonite, PAN/Na-MMT) are produced by electrospinning a solution of PAN in dimethylformamide containing synthetic Na-MMT. The influence of both Na-MMT amount and applied voltage on the properties of electrospun composite nonwovens was studied. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA-DTA) were used to evaluate the morphology, structure and thermal properties of composite nanofibers. SEM observations revealed that increasing the amount of Na-MMT in the solution or the applied voltage increases the average diameter of electrospun composite nanofibers. The prepared composite showed a higher thermal stability that the pristine PAN nanofibers. It was proven that the ion exchange properties of Na-MMT were maintained in the obtained composite. © 2015 The Korean Society of Industrial and Engineering Chemistry.

Vol. 464, pp. 153-159 
article DOI  
Abstract: The formation of a ternary antibiotic metal clay complex is hypothesized as the primary adsorption mechanism responsible for the increased adsorption of tetracycline antibiotics on smectites in the presence of divalent metal cations under circumneutral and higher pH conditions. To evaluate this hypothesis, we conducted a spectroscopic investigation of oxytetracycline (OTC) interacting with Na-montmorillonite in the presence and absence of Ca or Mg salts at pH 6 and pH 8. Despite a twofold increase in OTC adsorbed in the presence of Ca or Mg, both solid-state nuclear magnetic resonance and infrared signatures of the OTC functional groups involved in metal complexation implied that the formation of an inner-sphere ternary complexation was not significant in stabilizing the adsorbate structures. The spectroscopic data further indicated that the positively-charged amino group mediated the OTC adsorption both in the absence and presence of the divalent metal cations. Focusing on the experiments with Mg, X-ray diffraction analysis revealed that the metal-promoted adsorption was coupled with an increased intercalation of OTC within the montmorillonite layers. The resulting interstratified clay layers were characterized by simulating X-ray diffraction of theoretical stacking compositions using molecular dynamics-optimized montmorillonite layers with and without OTC. The simulations uncovered the evolution of segregated interstratification patterns that demonstrated how increased access to smectite interlayers in the presence of the divalent metal cations enhanced adsorption of OTC. Our findings suggest that specific aqueous structures of the clay crystallites in response to the co-presence of Mg and OTC in solution served as precursors to the interlayer trapping of the antibiotic species. Elucidation of these structures is needed for further insights on how aqueous chemistry influences the role of smectite clay minerals in trapping organic molecules in natural and engineered soil particles.

Intrusion-extrusion experiments of MgCl2 aqueous solution in pure silica ferrierite: Evidence of the nature of intruded liquid by in situ high pressure synchrotron X-ray powder diffraction 2016 Microporous and Mesoporous Materials
Vol. 235, pp. 253-260 
article DOI URL 
Abstract: Experimental intrusion-extrusion isotherms of MgCl2•21H2O solution were recorded at room temperature on pure silica FER-type zeolite (Si-FER). The intrusion occurs at 195 MPa and the phenomenon is completely reversible with a slight hysteresis. The “Si-FER - MgCl2 aqueous solution” system behaves like a spring. The material was deeply characterized before and after intrusion-extrusion experiments and no significant changes were observed. The unit cell parameters were refined – on the basis of the in situ synchrotron X-ray powder diffraction data - up to 1.47 GPa and then at Pamb upon pressure release. The Rietveld refinement of the data collected at 0.28 GPa (280 MPa), a pressure close to the intrusion value, shows that both ions and water molecules present in the MgCl2 aqueous solution were intruded in the porosities. However, the solvation degree of the intruded ions differs from the initial solution, revealing a partial desolvation of both magnesium and chloride ions. As a whole, the nature and amount of the intruded species correspond to a MgCl2•10H2O composition. Moreover, at a higher pressure (0.68 GPa), a phase transition from the orthorhombic Pmnn to the monoclinic P21/n s.g. is observed in Si-FER. At 1.47 GPa, the zeolite maintains this monoclinic symmetry, while another phase transition, to the monoclinic P21 s g., is argued from the analysis of the pattern of the sample compressed to 2.6 GPa and then collected upon pressure release to ambient conditions. © 2016

Vol. 336, pp. 1-10 
article DOI URL 
Abstract: The impact of crystal size and textural properties of ∗BEA-type zeolites in the conversion of ethanol-to-hydrocarbons at 350 °C and under 3.0 MPa pressure is investigated. Three ∗BEA zeolites (molar ratio Si/Al of ca. 23) with important differences concerning their textural properties are synthesized: a material constituted of micron-sized crystals and two hierarchical porous zeolites with a mesoporous network created either by the aggregation of nanometer-sized crystals or by the use of a gemini-type quaternary ammonium surfactant given a nano-sponge zeolite. The micrometric zeolite favors the formation of polyaromatic molecules in same proportion than the concentration of Brønsted acid sites. The deactivation mode of acid sites is poisoning rather than pore blocking. The short thickness of crystal in the nano-sponge zeolite combined with its low acidity, limit the growth of coke molecules as well as their accumulation inside micropores. Coke precursors (alkylbenzenes) are adsorbed on many silanol group located in the ordered mesopores, but the extreme downsizing of the zeolite crystal leads to an unexpected pore blocking by these light molecules. © 2016 Elsevier Inc.

Vol. 40(5), pp. 4335-4343 
article DOI  
Abstract: A series of *BEA-type zeolites with crystal sizes ranging from few nanometers to micrometers were synthesized. These materials were then transformed into bifunctional catalysts by platinum loading and tested in n-hexadecane isomerization. The behavior of Pt/H-*BEA catalysts depends on several parameters such as the balance between the platinum and acid functions, the metal particle size and the zeolite crystal size. In order to design an "ideal'' bifunctional catalyst, the metal and acid sites must be well balanced to avoid the cracking of isomer products at low conversion, the metal must be well dispersed in order to inhibit the hydrogenolysis side reactions, and the crystal size must be as small as possible to maximize the isomer yield. But, the extreme decrease of the zeolite crystal thickness to few zeolite unit cells lowers the turnover frequency of acid sites and favors the metal sintering.

Abstract: Two TICTOID-based pyridinium-phenolates bearing a crown ether macrocycle have been designed for the complexation of potassium cation. The nucleophilicity of the intraannular phenolate -O- function can be strongly modulated by biaryl twisting. Such a structure/electronic transduction effect gives rise to a host-guest binding change by more than two orders of magnitude.

Vol. 49(6), pp. 2124-2134 
article DOI URL 
Abstract: In the present paper, four fluorescent materials currently used in organic light emitting diodes (OLEDs) are presented in an original way as high performance photocatalysts usable in polymerization photoinitiating systems. Their performance is excellent in free radical polymerization, cationic polymerization but also in the synthesis of interpenetrating polymer networks (IPNs). A coherent picture of the chemical mechanisms involved in these new photocatalytic systems is provided. Remarkably, an oligomeric and copolymerizable photocatalyst (PVD2) is proposed here for the first time, i.e., both the high molecular weight of PVD2 and the presence of reactive double bonds as end groups (which could be involved in a copolymerization reaction) ensure a very low migration of the catalyst from the synthesized polymer. © 2016 American Chemical Society.

Vol. 145, pp. 1-7 
article DOI URL 
Abstract: A polystyrene surface (PS) was initially treated by cold nitrogen and oxygen plasma in order to incorporate in particular amine and hydroxyl functions, respectively. The evolution of the chemical nature of the surface was further monitored over a long time period (580 days) by chemical assay, XPS and contact angle measurements. Surface density quantification of primary amine groups was performed using three chemical amine assays: 4-nitrobenzaldehyde (4-NBZ), Sulfo succinimidyl 6-[3'(2 pyridyldithio)-pionamido] hexanoate (Sulfo-LC-SPDP) and iminothiolane (ITL). The results showed amine densities were in the range of 2 per square nanometer (comparable to the results described in the literature) after 5 min of nitrogen plasma treatment. Over the time period investigated, chemical assays, XPS and contact angles suggest a drastic significant evolution of the chemical nature of the surface within the first two weeks. Beyond that time period and up to almost two years, nitrogen plasma modified substrates exhibits a slow and continuous oxidation whereas oxygen plasma modifed polystyrene surface is chemically stable after two weeks of storage. The latter appeared to "ease of" showing relatively mild changes within the one year period.Our results suggest that it may be preferable to wait for a chemical "stabilization" period of two weeks before subsequent covalent immobilization of proteins onto the surface. The originality of this work resides in the study of the plasma treated surface chemistry evolution over long periods of storage time (580 days) considerably exceeding those described in the literature. © 2016 Elsevier B.V.

Abstract: The study of fuel oxidation stability is an important issue for the development of future fuels. Diesel and kerosene fuel systems have undergone
several technological changes to fulfill environmental and economic requirements. These developments have resulted in increasingly severe
operating conditions whose suitability for conventional and alternative fuels needs to be addressed. For example, fatty acid methyl esters
(FAMEs) introduced as biodiesel are more prone to oxidation and may lead to deposit formation. Although several methods exist to evaluate
fuel stability (induction period, peroxides, acids, and insolubles), no technique allows one to monitor the real-time oxidation mechanism and
to measure the formation of oxidation intermediates that may lead to deposit formation. In this article, we developed an advanced oxidation
procedure (AOP) based on two existing reactors. This procedure allows the simulation of different oxidation conditions and the monitoring
of the oxidation progress by the means of macroscopic parameters, such as total acid number (TAN) and advanced analytical methods like
gas chromatography coupled to mass spectrometry (GC-MS) and Fourier Transform Infrared - Attenuated Total Reflection (FTIR-ATR). We
successfully applied AOP to gain an in-depth understanding of the oxidation kinetics of a model molecule (methyl oleate) and commercial diesel
and biodiesel fuels. These developments represent a key strategy for fuel quality monitoring during logistics and on-board utilization

Vol. 399, pp. 199-206 
article DOI  
Abstract: 25 nm to 50 nm Co2FeAl (CFA) thick wire arrays with varying widths and spacing have been patterned from continuous CFA films deposited on MgO(001) using e-beam lithography and Ar ion milling. Magneto-optical Kerr effect, transverse bias initial inverse susceptibility and torque measurements reveal that the in-plane magnetic anisotropy of the wires is dominantly monitored by a uniaxial term, in contrast with the continuous films where it is governed by the superposition of a fourfold term and of a smaller uniaxial term. The microstrip ferromagnetic resonance spectra performed using a magnetic field H, applied in the plane of the studied sample along various directions, or perpendicularly to this plane, gave us access to various quantized modes originating from the patterning. In addition, Brillouin light scattering also exhibits quantized modes. A large part of the experimental observations can be quantitatively interpreted as resulting from the demagnetizing terms induced by the geometrical patterning. However, the presented model, simply built on the effect of the demagnetizing field, is not able to give account of all the quantized modes present in the resonance spectra. When H is parallel to the wires, a more complete description is used: it considers the wave-vector quantization induced by the patterning. For the magnetic modes concerned by both approaches, the correspondence between the 2 models is easily established. When H is not parallel to the wires quantitative descriptions of the behavior of the field dependence of the observed modes still can often be performed. Finally, in all the studied patterned samples, the uniform magnetic mode, termed "film mode", relative to the parent continuous film is observed by ferromagnetic resonance: such a behavior, which has been reported previously, remains to be completely interpreted.

Vol. 40(5), pp. 4386-4397 
article DOI  
Abstract: Two series of TiO2-SiO2 composites have been prepared by post-synthesis impregnation of a TiO2 precursor onto SBA-15 silica matrices and subsequent thermal treatment at 400 degrees C in air. The influence of the textural properties of the SBA-15 and the TiO2 content was evaluated upon the dispersion of TiO and its crystallization in anatase. The morphology of the samples before and after impregnation was observed by electronic microscopy while the textural and structural properties were evaluated by different techniques such as XRD, nitrogen sorption manometry, and Raman spectroscopy. The quantity of crystallized anatase in the composites was determined by XRD quantification using an internal standard. The bandgap energy (E-g) of the composites was evaluated by diffuse reflectance spectroscopy and the results show that E-g decreases as a function of the titania content. The photoactivity of the prepared materials was evaluated by following the degradation of methyl orange (MO) in water under UV irradiation. For the same amount of catalyst, the MO degradation rate in the presence of the composites containing 28 and 44 wt% of crystallized anatase was found to be similar to the one in the presence of commercial fully crystallized anatase.

Blas, L., Dutournié, P., Dorge, S., Josien, L., Kehrli, D. and Lambert, A. Thermal stability study of NiAl2O4 binders for Chemical Looping Combustion application 2016 Fuel
Vol. 182, pp. 50-56 
article DOI URL 
Abstract: The influence of the preparation method of NiAl2O4 binders on their thermal stability was studied. For this purpose, the reactivity of two different NiAl2O4 binders with CO as fuel was studied in a fixed bed reactor device. Successive oxidation-reduction cycles were performed on the two binders to study their reactivity with the fuel and their structural modifications as cycles proceed. Results reveal that binders are not inert in reducing atmosphere; they both react with the fuel to produce CO2. The total reduction capacity (TRC) of the first binder (B1, synthetized by pyrolytic pulverization) increases during the first cycles and levels off after 20 cycles. However, the TRC of the second binder (B2, synthetized by calcination of a mixture of Ni(OH) and γ-Al2O3), increases progressively and reaches a maximum after 80 cycles. The growing amount of available oxygen in the binders leads both binders to structural modifications. X-ray Diffraction studies performed on fresh and aged binders presented a shift of the peaks related to NiAl2O4. Moreover, quantitative X-ray Diffraction studies and Temperature Programmed Reduction measurements were performed in order to quantify the NiO present in each binder before and after oxidation-reduction cycles. These experiments revealed the presence of NiO in fresh binders due to the preparation method, and an increase of this amount after oxidation-reduction cycles. Therefore, NiAl2O4 in the binder is progressively decomposed producing NiO and Al2O3. Finally, the decomposition of the binder NiAl2O4 as cycles proceed was also observed in studies performed on the oxygen carrier NiO/NiAl2O4. This work showed that the binder reacts with the fuel and therefore it can contribute to the modification of the oxygen carrier reactivity. © 2016 Elsevier Ltd.

Vol. -(-), pp. 1-12 
article DOI URL 
Abstract: Membrane separation processes find applications in an array of fields as they use far less energy and chemical agents than competing processes. However, a major drawback of membrane technology is that biofilm formation alters membrane performances. Preventing biofilm formation is thus a pivotal challenge for larger-scale development of membrane processes. Here, we studied the comparative antibacterial activities of different inorganic membranes (ceramic and zeolite-coated ceramic with or without copper exchange) using several bacterial strains (Escherichia coli, Staphylococcus aureus, and Bacillus subtilis). In static conditions, alumina plates coated with Cu-exchanged zeolite showed significant bactericidal activity. In dynamic mode (circulation of a contaminated nutrient medium), there was no observable bacterial adhesion at the surface of the Cu-exchanged material. These results confirm the antifouling properties of the Cu-mordenite layer due to both the increased hydrophilicity and antibacterial properties of the active layer. Tests performed with tubular filtration membranes (without copper exchange) showed a significant decline in membrane hydraulic properties during filtration of culture media containing bacteria, whereas copper-exchanged membranes showed no decline in hydraulic permeability. Filtration tests performed with concentrated culture media containing spores of B. subtilis led to a significant decrease in membrane hydraulic permeabilities (but less so with Cu-exchanged membranes). The surfaces showed less effective global antifouling properties during the filtration of a concentrated culture medium due to competition between bacterial growth and the bactericidal effect of copper. Analyses of copper leached in solution show that after a conditioning step, the amount of copper released is negligible. © 2016 Springer-Verlag Berlin Heidelberg

Vol. 25, pp. 75-82 
article DOI URL 
Abstract: Nano-emulsions known also as mini-emulsions, ultrafine emulsions or submicron emulsions are a specific kind of emulsions that have a sub-micrometer droplet size and a low polydispersity. Nano-emulsions, being kinetically stable systems, require energy input in order to be formed, either from mechanical devices or from the intrinsic physicochemical potential of the components. The properties of the nano-emulsions make them suitable for applications in various domains such as drug delivery, cosmetics, pesticides and in particular for the preparation of inorganic or hybrid nanostructured materials. This review discusses the recent progresses made in this latest field. We focus on inorganic or hybrid nanoparticles, nanocapsules, hollow spheres or composites prepared by combining the nano-emulsion technique and the sol-gel process. In that case nano-emulsions act as template. We also outline the most recent development, which consists in using the nano-emulsions as imprints to get hierarchical porous silica materials. © 2016 Elsevier Ltd

Photo-optical properties of amorphous and crystalline films of azobenzene-containing photochromes with bent-shaped molecular structure 2016 Journal of Photochemistry and Photobiology A: Chemistry
Vol. 316, pp. 75-87 
article URL 
Abstract: Abstract A comparative study of the photo-optical properties and the photo-orientation processes in thin films of the bent-shaped azobenzene-containing compounds with different molecular structure was performed. For this purpose three new compounds were designed and prepared: two of these compounds with a symmetric bent-shaped molecular structure incorporate two azobenzene chromophores with different length of alkyl chains (6 and 8 methylene units), the third bent-shaped compound possesses only one azobenzene fragment. The effect of molecular and supramolecular structure, thermal prehistory of the films, wavelengths of the excitation light on the photo-optical properties, photoorientation processes and films morphology was revealed. It was shown that UV-irradiation leads to E-Z isomerization of azobenzene fragments in both amorphousized and crystalline films of the synthesized substances. This process is partially suppressed in crystalline films, but, nevertheless, UV-irradiation of the bichromophoric compounds results in transition from crystalline to amorphous state and decrease in the surface roughness. Irradiation of amorphousized films with polarized visible and UV-light induces the photoorientation of chromophores in direction perpendicular to the polarization plane of the incident light. Relatively high values of photoinduced dichroism in the bent-shaped compounds (D ∼ 0.60-0.65) are comparable with other azobenzene-containing rod-shaped systems. Photoinduced isothermal melting and photoorientation processes could be served for the photo-optical data recording and storage.

Vol. 127, pp. 1-8 
article DOI URL 
Abstract: A water soluble dye, the Red 33, used in cosmetic industry was immobilized into mesoporous silica by a one-step method which consists in the introduction of the dye molecules in the precursor medium of the mesoporous silica i.e. containing surfactant and silica source. A high loading rate of 25 wt% was achieved. The resulting Red 33-silica pigment is stable in water and oil media. The characterizations carried out on this material have shown that the encapsulation is effective and that the presence of Red 33 has an effect on the structure and texture of the material. The material exhibits an excellent stability in water due to the interactions between the Red 33 molecules, the silicate species and the surfactant molecules. It has been shown that the dye molecules interact with both the silica host matrix through the NH2 and phenyl groups, as well as with the surfactant molecules, via electrostatic interactions between the polar head of the surfactant and the sulfonate group of Red 33 which undergoes no steric hindrance. © 2015 Elsevier Ltd.

Vol. 19(4)Comptes Rendus Chimie, pp. 457-465 
article URL 
Abstract: Although the influence of metallic and alkaline elements on biomass char reactivity is well known, a quantitative assessment of this catalytic effect is hard to obtain because of the chemical and textural complexity of biomass. The effect of K and Si on the CO2 gasification reactivity of a biomass char was studied using thermogravimetric analysis. A beech sample was pyrolyzed at 800 °C and then impregnated with known amounts of silicon or potassium allowing to obtain a wide range of K/Si ratios. The reactivity of the impregnated samples was studied under a CO2 (20% vol.) atmosphere. The results show that at low conversion ratios, the char reactivity depends on its textural properties, with strong diffusional limitations. When conversion reaches 60%, the presence of a catalyst (K) and an inhibitor (Si) becomes the major parameter influencing reactivity. From these experiments, a general trend was obtained between K/Si ratio and reactivity as a function of conversion. © 2016 Académie des sciences.

Abstract: Despite kerogen’s importance as the organic backbone for hydrocarbon production from source rocks such as gas shale, the interplay between kerogen’s chemistry, morphology and mechanics remains unexplored. As the environmental impact of shale gas rises, identifying functional relations between its geochemical, transport, elastic and fracture properties from realistic molecular models of kerogens becomes all the more important. Here, by using a hybrid experimental–simulation method, we propose a panel of realistic molecular models of mature and immature kerogens that provide a detailed picture of kerogen’s nanostructure without considering the presence of clays and other minerals in shales. We probe the models’ strengths and limitations, and show that they predict essential features amenable to experimental validation, including pore distribution, vibrational density of states and stiffness. We also show that kerogen’s maturation, which manifests itself as an increase in the sp2/sp3 hybridization ratio, entails a crossover from plastic-to-brittle rupture mechanisms. © 2016 Nature Publishing Group

Abstract: Objectives The aim of our study is to find an amine free photoinitiating system (PIS) for the polymerization of representative dental methacrylate resins. A photoinitiating system (PIS) based on camphorquinone (CQ)/triphenylgermanium hydride/diphenyl iodonium hexafluorophosphate is proposed and compared to the conventional CQ/amine couple. The polymerization monitoring of thin (∼20 μm) and thick (1.4 mm) samples of a bisphenol A-glycidyl methacrylate (Bis-GMA)/triethyleneglycol dimethacrylate (TEGDMA) blend (70%/30% w/w) and of a urethane dimethacrylate (UDMA) upon exposure to a commercial blue LED centered at 477 nm under air or in laminate is described. Finally, the impact of the photoinitiating system composition on the final polymer color is evaluated in detail. Methods FTIR and DSC experiments are used to record the photopolymerization profiles. ESR spectrometry and steady state photolysis are used to detect the produced radicals. Color measurements are carried out to determine the key parameters in the bleaching of the different dental formulations. Results The efficiency of the newly proposed PISs for the photopolymerization of BisGMA/TEGDMA and UDMA for thin (20 μm) or for thick (1.4 mm) samples upon exposure to a dental blue LED under air is excellent. It is noticeably higher than that of the CQ/amine reference couple. Excellent bleaching properties are also observed under irradiation in presence of the new PISs. A good correlation is found between the sample bleaching and the amount of Ph3GeH in the formulation. The excited state processes could be established. The overall chemical mechanisms for the initiation step were also clarified. © 2016 The Academy of Dental Materials

Vol. 18(11), pp. 3265-3271 
article DOI URL 
Abstract: Ordered mesoporous carbons were prepared by the self-assembly of Mimosa tannin, a natural polyphenolic molecule, and a micellar solution of Pluronic® F127, used as soft template. The synthesis was carried out at 20 °C using water as the only solvent and without crosslinker agent (i.e., formaldehyde). When tannin, at any pH lower than 4.2, and Pluronic solutions were mixed, a phase separation mechanism immediately occurred due to the strong interaction between both polymers. The precipitated resin was recovered, dried and pyrolysed at 400, 700 and 900 °C. Ordered mesoporous carbon materials were obtained, having both high pore volume and surface areas, up to 0.64 cm3 g-1 or 720 m2 g-1, respectively. © 2016 The Royal Society of Chemistry.

article DOI  
Abstract: This work focuses on different ways to improve the yield and/or the crystalline state of EMT/FAU-type zeolite nanocrystal aggregates obtained in the presence of organic additive triethanolamine (TEA). The increase of the amount of aluminum reagent enhances the synthesis yield by a factor of 2.5 without affecting the crystallization rate and the microporous volume. On the other hand, the increase of the thermal treatment time allows to increase the synthesis yield, the crystallization rate and the microporous volume. Furthermore, adding EMT zeolite seeds in the starting reaction medium improves the crystallization rate and the microporous volume.

Characterisation and seasonal variations of particles in the atmosphere of rural, urban and industrial areas: Organic compounds 2016 Journal of Environmental Sciences
Vol. 44(Supplement C), pp. 45-56 
article URL 
Abstract: Abstract Atmospheric aerosol samples (PM2.5-0.3, i.e., atmospheric particles ranging from 0.3 to 2.5μm) were collected during two periods: spring-summer 2008 and autumn-winter 2008-2009, using high volume samplers equipped with cascade impactors. Two sites located in the Northern France were compared in this study: a highly industrialised city (Dunkirk) and a rural site (Rubrouck). Physicochemical analysis of particulate matter (PM) was undertaken to propose parameters that could be used to distinguish the various sources and to exhibit seasonal variations but also to provide knowledge of chemical element composition for the interpretation of future toxicological studies. The study showed that PM2.5-0.3 concentration in the atmosphere of the rural area remains stable along the year and was significantly lower than in the urban or industrial ones, for which concentrations increase during winter. High concentrations of polycyclic aromatic hydrocarbons (PAHs), dioxins, furans and dioxin like polychlorinated biphenyls (DL-PCBs), generated by industrial activities, traffic and municipal wastes incineration were detected in the samples. Specific criteria like Carbon Preference Index (CPI) and Combustion PAHs/Total PAHs ratio (CPAHs/TPAHs) were used to identify the possible sources of atmospheric pollution. They revealed that paraffins are mainly emitted by biogenic sources in spring-summer whereas as in the case of PAHs, they have numerous anthropogenic emission sources in autumn-winter (mainly from traffic and domestic heating).

Vol. 10(6), pp. 439-449 
article DOI  
Abstract: We describe a novel combination of orthogonal reactions based on UV-driven thiol-ene and alkoxysilyl condensation reactions to form a single-step route toward thioether-bridged silsesquioxane films. Our chemical strategy consists of using two bifunctional (meth) acrylate (E) and propanethiol (T) trimethoxysilyl precursors containing two complementary functional moieties for thiol-ene coupling and sol-gel process. The reaction kinetics revealed that c.a. 85% of thiol and ene conversions were consumed concomitantly. Meanwhile, a complete hydrolysis was accomplished, affording ultimately a high degree of condensation (81%). Emphasis was placed on differences of mechanical properties between sol-gel hybrids resulting from thiol-ene reaction (E-T mixture) and ene homopolymerization (E only) using scratch test measurements. For the methacrylate system, the formation of thioether linkages within a vitreous silica network emerged as a useful strategy for the formation of a uniform, low-stress and flexible crosslinked hybrid structure. Enhanced mechanical properties were manifested by an expanded elastic domain, and better resistance to cracking. Moreover, there are clear indications that mechanical properties can be easily tuned upon varying the ratio of the two hybrid precursors.

Vol. 10(3), pp. 261-268

Abstract: The continuous photopolymerization of acrylate and methacrylate monomer miniemulsions (25% solids content) is investigated at room temperature in a compact helix minireactor. Using n-butyl acrylate, the process yields 95% conversion after only 27 s residence time, and gel-free high-molecular-weight products. Under optimized conditions, a 25-fold increase in efficiency is obtained when compared to a batch photopolymerization. The reaction set-up offers a frugal process because of moderate irradiance (2.6 mW cm(-2)), photoinitiator concentration (0.75 wt%), and low-power UV-A fluorescent lamp.

Vol. 7, pp. 1338-1349 
article DOI  
Abstract: Ce-doped ZnO (ZnO:Ce) nanorods have been prepared through a solvothermal method and the effects of Ce-doping on the structural, optical and electronic properties of ZnO rods were studied. ZnO:Ce rods were characterized by XRD, SEM, TEM, XPS, BET, DRS and Raman spectroscopy. 5% Ce-doped ZnO rods with an average length of 130 nm and a diameter of 23 nm exhibit the highest photocatalytic activity for the degradation of the Orange II dye under solar light irradiation. The high photocatalytic activity is ascribed to the substantially enhanced light absorption in the visible region, to the high surface area of ZnO:Ce rods and to the effective electron-hole pair separation originating from Ce doping. The influence of various experimental parameters like the pH, the presence of salts and of organic compounds was investigated and no marked detrimental effect on the photocatalytic activity was observed. Finally, recyclability experiments demonstrate that ZnO:Ce rods are a stable solar-light photocatalyst.

Vol. 329, pp. 77-87

Abstract: Abstract Two different groups of methacrylates containing Type I or Type II photoinitiating moieties were synthesized and evaluated for use in UV curing applications. The first, a novel group of monomeric photoinitiators (MPIs) were synthesized by reactions of tert-butyl α-bromomethacrylate (TBBr) with 2-hydroxy-1-[4-(2-hydroxyethoxy)phenyl]-2-methyl-1-propanone (Irgacure 2959), 1-hydroxy-cyclohexyl-phenyl-ketone (Irgacure 184) and 4-hydroxyacetophenone to give monomers MPI1, MPI3 and MPI4 respectively; and conversion of MPI1 to MPI2 by cleavage of tert-butyl ester groups with trifluoroacetic acid. The second group of photoinitiators were synthesized by reaction of 2-isocyanatoethyl methacrylate (IEM) with Irgacure 2959 (MPI5) and 4-hydroxybenzophenone (MPI6). All these MPIs’ absorption range in the UV region was found to be similar to their nonmonomeric analogs. Their photoinitiating abilities in the polymerizations of hexane-1,6-diol diacrylate (HDDA), 2-hydroxyethyl methacrylate (HEMA) and trimethylolpropane triacrylate (TMPTA) were studied using photodifferential scanning calorimeter and the kinetic parameters were correlated with the structures of the photoinitiating systems. Photoinitiating activities of investigated Type I photoinitiators, including small molecule commercial analogs, during polymerizations of HDDA and TMPTA are very slightly influenced by MPIs structure. However, the MPI structure is found to be important for the curing of HEMA, and some of the synthesized MPIs have better efficiency than commercial ones tested. The MPIs based on Irgacure 2959, Irgacure 184 and benzophenone (BP), with similar or increased photoinitiating activity compared to their commercial precursors, appear to be promising photoinitiators. An extra advantage of MPIs is their incorporation into the final formulations, reducing undesired migration of small molecules.

Vol. 6(22), pp. 18235-18245 
article DOI  
Abstract: The development of new antibacterial coatings (against Escherichia coli and Staphylococcus aureus) using a natural dye, quercetin, according to a green chemistry process was investigated. Quercetin was used as both a photosensitizer and antibacterial agent. The synthesized material was developed according to a cationic photopolymerization process under light irradiation. The photosensitizing mechanism involving quercetin and an iodonium-based cationic photoinitiator was described for the first time according to steady state photolysis and fluorescence experiments. The resulting coatings showed excellent adhesion on a stainless steel plate as demonstrated by nanoindentation and scratch tests, with a high thermal stability up to 375 degrees C. Finally, a primary investigation was conducted to assess the antibacterial properties of the glycerol-derived coatings against Escherichia coli and Staphylococcus aureus under light illumination. Electron paramagnetic resonance spectroscopy confirmed the generation of reactive oxygen species, such as singlet oxygen, which is responsible for inhibiting bacteria proliferation.

Abstract: Abstract A series of five octupolar molecules with central triphenylamine donor and peripheral diazine electron-withdrawing groups has been prepared. These structures possess extended π-spacer comprising multiple bonds in a combination with 1,4-phenylene and 2,5-thienylene subunits. Starting from tris(4-ethynylphenyl)amine, the key step in the preparation of the chromophores involves triple Sonogashira cross-coupling reaction. The photophysical properties of the compounds are described. A strong positive emission solvatochromism, typical for dyes featuring Intramolecular Charge Transfer (ICT), is observed, two-photon absorption (2 PA) properties were also measured. Linear and nonlinear optical properties as well as electronic properties measured by cyclic voltametry and supported by DFT calculation were used to elucidate structure-property relationships.

Abstract: Based on a low temperature scanning tunneling microscopy study, we present a direct visualization
of a cycloaddition reaction performed for some speci c
uorinated maleimide molecules
deposited on graphene. These studies showed that the cycloaddition reactions can be carried out
on the basal plane of graphene, even when there are no pre-existing defects. In the course of
covalently grafting the molecules to graphene, the sp2 conjugation of carbon atoms was broken
and local sp3 bonds were created. The grafted molecules perturbed the graphene lattice, generating
a standing-wave pattern with an anisotropy which was attributed to a (1,2) cycloaddition,
as revealed by T-matrix approximation calculations. DFT calculations showed that while both
(1,4) and (1,2) cycloaddition were possible on free standing graphene, only the (1,2) cycloaddition
could be obtained for graphene on SiC(0001). Globally averaging spectroscopic techniques, XPS
and ARPES, were used to determine the modi cation in the elemental composition of the samples
induced by the reaction, indicating an opening of an electronic gap in graphene.

Vol. 16(1), pp. 432-439 
article DOI  
Abstract: The interest in co-crystals of energetic materials is explained by the fact that they can offer better thermodynamic stability and tunable sensitivity and detonation performance. In the present work, a combination of DSC, ultrafast chip calorimetry, high-resolution X-ray powder diffraction, and nanofocus X-ray diffraction was employed to investigate the thermal behavior and structure formation in nanosized co-crystals of CL-20 with HMX and TNT prepared using Spray Flash Evaporation (SFE). The CL-20/HMX cocrystal does not reveal any thermal transitions up to the thermal decomposition. In contrast, CL-20/TNT exhibits an irreversible melting transition. Upon melting, it can rapidly crystallize on heating or, at a slower pace, at room temperature to form homocrystals of gamma CL-20, the polymorph stable at high temperature. These observations constitute the first evidence of a CL-20 crystallization process, which occurs from the melt and not from solution. The solid-liquid phase separation occurring during heating CL-20-TNT melt may explain its complex thermal decomposition process as compared to that of CL-20/HMX: the main exothermic peak of decomposition can be assigned to that of a pure CL-20.

Abstract: ConspectusPhotoinitiated polymerization has been the subject of continued research efforts due to the numerous applications in which this polymerization technique is involved (coatings, inks, adhesives, optoelectronic, laser imaging, stereolithography, nanotechnology, etc.). More recently, photopolymerization has received renewed interest due to the emergence of 3D-printing technologies. However, despite current academic and industrial interest in photopolymerization methodologies, a major limitation lies in the slow rates of photopolymerization. The development of new photoinitiating systems aimed at addressing this limitation is an active area of research. Photopolymerization occurs through the exposure of a curable formulation to light, generating radical and/or cationic species to initiate polymerization. At present, photopolymerization is facing numerous challenges related to safety, economic and ecological concerns. Furthermore, practical considerations such as the curing depth and the competition for light absorption between the chromophores and other species in the formulation are key parameters drastically affecting the photopolymerization process. To address these issues, photoinitiating systems operating under low intensity visible light irradiation, in the absence of solvents are highly sought after.In this context, the use of photoredox catalysis can be highly advantageous; that is, photoredox catalysts can provide high reactivities with low catalyst loading, permitting access to high performance photoinitiating systems. However, to act as efficient photoredox catalysts, specific criteria have to be fulfilled. A strong absorption over the visible range, an ability to easily oxidize or reduce as well as sufficient photochemical stability are basic prerequisites to make these molecules desirable candidates for photoredox catalysis. Considering the similarity of requirements between organic electronics and photopolymerization, numerous materials initially designed for applications in organic electronics have been revisited in the context of photopolymerization. Organic electronics is a branch of electronics and materials science focusing on the development of semiconductors devoted to three main research fields; organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic solar cells (OSCs). The contribution of organic electronics to the field of electronics is important as it paves the way toward cheaper, lighter, and more energy efficient devices. In the present context of photopolymerization, materials that were investigated as photocatalysts were indifferently organic semiconductors used for transistors, charge-transport materials, and light-emitting materials used in electroluminescent devices or conjugated polymers and small molecule dyes for solar cells. In this Account, we summarize our latest developments in elaborating on photocatalytic systems based on these new classes of compounds. Through an in-depth understanding of the parameters governing their reactivities and our efforts to incorporate these materials into photoinitiating systems, we provide new knowledge and a valuable insight for future prospects. © 2016 American Chemical Society.

Vol. 12(1), pp. 45-52 
article DOI  
Abstract: Elastomer polydimethylsiloxane (PDMS) films with embedded in-plane gradient stress are created by making PDMS/(PDMS + silicone oil) crosslinked bilayers and extracting the oil in a suitable organic solvent bath. The collapse of the elastomer after oil extraction generates differential stress in the films that is manifested through their out-of-plane deformation. The curvature k of narrow stripes of the bilayer, which is composed of layers of approximately equal thicknesses and elasticity moduli, is satisfactorily described by the simple relationship k = 1.5dH(-1), where delta is the mechanical strain, and H is the total thickness of the bilayer. Curvature mapping of triangular PDMS plates reveals the existence of spherical and cylindrical types of deformation at different locations of the plates. Various 3D-shaped objects can be formed by the self-folding of appropriately designed 2D patterns that are cut from the films, or by nonuniform distribution of the collapsing layer. Thin PDMS bilayers with embedded stress roll up into microtubes of almost perfect cylindrical shape when released in a controlled manner from a substrate.

Vol. 233, pp. 39-47 
article DOI  
Abstract: In this article we present a relevant strategy for a non-trivial time-programmed release of water-soluble macromolecules from biocompatible mu-containers. The system is based on self-scrolled chitosan acetate (CA) fibers, encapsulated in a poly(dimethylsiloxane) matrix. Mass transfer between a fiber and the external environment takes place via the only opened extremity of the fiber. Fluoroscein isocyanate dextran (FID) is initially deposited at the inner surface of the CA fiber according to a programmed pattern. The FID molecules became mobile after the arriving of the swelling front, which propagates along the fiber's axis upon the immersion of the system in aqueous solution. Diffusion of the macromolecules into the environment is enabled by the open-tube geometry of the swollen part of the fiber, while a programmed kinetics of the drug release is due to patterning of the polymer film prior to rolling. The release of the macromolecules can be retarded by a few hours according to the placement of the FID spot with respect to the fibers orifice. A pulsatile release kinetics is demonstrated for a discrete pattern. A few millimeter spacing of the FID spots results in a few hours time interval between the release impulses. Random walk model is plugged in the effective diffusion coefficient for Fick's law and the release kinetics are simulated. (C) 2016 Elsevier B.V. All rights reserved.

Abstract: Thermal degradation of different date palm residues (three fibrous materials and an agro-industrial by-product) under inert and oxidative atmospheres was investigated in order to identify the degradation mechanisms and kinetics of the main thermal decomposition stages using Coats-Redfern method. The corresponding kinetic parameters of the main degradation stages were also determined. The obtained results have shown that diffusion and reaction order models are the best mechanisms describing effectively thermal degradation of the different palm date residues under both atmospheres. The obtained kinetics parameters may help predicting the pyrolysis and combustion behavior of date palm residues as well as designing the suitable reactor.

Vol. 217(13), pp. 1501-1512 
article DOI URL 
Abstract: Five novel thioxanthone (TX)-functionalized methacrylates as copolymerizable photoinitiators (CopPIs) for polymerization of acrylates are synthesized from reactions of tert-butyl α-bromomethacrylate with 2-hydroxy thioxanthone (TX1) and 1,4-dihydroxy thioxanthone (TX3), cleavage of their respective tert-butyl ester groups with trifluoroacetic acid (TX2, TX4), and by reaction of the acid chloride derivative of TX2 with Irgacure 2959 (TX5). These CopPIs absorb in the near UV–visible region (390–420 nm; absorption redshift ≈10–40 nm, ε values comparable to TX). Their performances are studied under LED exposure at 385 and 405 nm using real-time FTIR. The reactivities of TX1 and TX2 are similar to isopropyl thioxanthone, used as reference; TX3 and TX4 have lower reactivities, due to their difunctionality, which however makes them good crosslinking agents. TX5 is the first monomeric PI possessing two different type side-chain photoinitiating groups. The migration stability of two of these CopPIs is shown in the cured polyacrylates. The photochemical mechanisms are studied by electron spin resonance, steady state photolysis, laser flash photolysis, and cyclic voltammetry. (Figure presented.) . © 2016 WILEY-VCH Verlag GmbH & Co.

Vol. 54(20), pp. 3370-3378 
article DOI URL 
Abstract: The photochemical and photophysical properties of new polymeric photoinitiators (PPIs) containing pendant thioxanthone (TX) and amine moieties are studied. The PPIs are synthesized by copolymerization of tert-butyl 2-((9-oxo-9H-thioxanthen-2-yloxy)methyl)acrylate (TX1) with N,N-dimethylaminoethyl methacrylate (DMAEM) at two different ratios using free radical polymerization. UV–vis spectra indicate that PPIs possess similar absorption characteristics to TX1 in the violet range (∼400 nm; absorption red-shift 20 nm). The photochemical mechanisms are studied by electron spin resonance (ESR), steady state photolysis, laser flash photolysis, and cyclic voltammetry. ESR studies indicate formation of two different aminoalkyl radicals on the hydrogen donor amine. The triplet state of the PPIs is short-lived compared to isopropyl thioxanthone and TX1, due to the built-in amine functionality. Photopolymerization of trimethylolpropane triacrylate (TMPTA) initiated by these photoinitiators under LED exposure at 385 and 405 nm using real-time FTIR spectroscopy shows that they exhibit higher efficiency than TX/N-methyldiethanolamine (MDEA) and TX1/MDEA systems with the advantage of a much higher molecular weight that can be very helpful to overcome migration issues. © 2016 Wiley Periodicals, Inc.

Vol. 4(2), pp. 286-294 
article DOI  
Abstract: Charge transport in conjugated polymers is critical to most optoelectronic devices and depends strongly on the polymer structure and conformation in the solid state. Understanding the correlations between charge carrier mobility, energy disorder and molecular assembly is therefore essential to improve device performances. Alkyl side-chains contribute to intermolecular interactions and are key to controlling the polymer microstructure and electronic properties. Investigating a set of polymers with common conjugated units but different side-chain functionalization provides new insights into the complex structure-transport relationship. Here, field-effect transistors and space-charge-limited current devices are used together with in situ grazing-incidence wide-angle X-ray scattering to study charge transport and morphology in a series of donor-acceptor copolymers. Probing hole mobility as a function of carrier density and orientation permits us to assess energy disorder and hopping rate anisotropy, while X-ray diffraction allows us to link transport properties to the polymer microstructure. We show that branched side-chains enhance structural and energy disorder and lead to isotropic transport, whereas linear chains induce either a common lamellar structure or a more exceptional pseudo-hexagonal columnar phase with a helicoidal polymer conformation. The latter enhances out-of-plane mobility but increases energy disorder possibly due to larger interring torsion angles.

Vol. 37(2), pp. 155-60 
article DOI  
Abstract: Initially developed as an elastomer with an excellent record of barrier and chemical resistance properties, poly(disulfide) has experienced a revival linked to the dynamic nature of the S-S covalent bond. A novel photobase-catalyzed oxidative polymerization of multifunctional thiols to poly(disulfide) network is reported. Based solely on air oxidation, the single-step process is triggered by the photodecarboxylation of a xanthone acetic acid liberating a strong bicyclic guanidine base. Starting with a 1 mum thick film based on trithiol poly(ethylene oxide) oligomer, the UV-mediated oxidation of thiols to disulfides occurs in a matter of minutes both selectively, i.e., without overoxidation, and quantitatively as assessed by a range of spectroscopic techniques. Thiolate formation and film thickness determine the reaction rates and yield. Spatial control of the photopolymerization serves to generate robust micropatterns, while the reductive cleavage of S-S bridges allows the recycling of 40% of the initial thiol groups.

Abstract: Hydrolysis and condensation reactions involved in the synthesis of organic-inorganic talc like hybrids (TLH) starting from diethylphosphatoethyltriethoxysilane (SiP), magnesium nitrate (Mg(NO3)2), ethanol and sodium hydroxide have been studied. The influence of magnesium nitrate, concentration of NaOH aqueous solution and pH value of the reaction media was investigated by high resolution 1H, 29Si and 31P liquid Nuclear Magnetic Resonance (NMR) and 29Si and 31P solid state NMR. It was shown that Mg(NO3)2 has a catalytic effect on the hydrolysis-condensation reaction rates of SiP and that high concentrations of NaOH lead to a scission of siloxane bonds as well as a partial hydrolysis of ethoxy groups linked to phosphorous. The final TLH products have been characterized by solid state 29Si NMR.

Abstract: A novel way to counterbalance the drawbacks and advantages of photopolymerization and redox polymerization is proposed. Photoinitiating systems based on charge transfer complexes (CTC) between a phosphine and an iodonium salt as well as an amine and iodonium salt are checked for the free radical polymerization of methacrylates. Polymer materials as thick as 8.5 cm can be produced under air upon exposure to a LED at 405 nm using an amine/phosphine/iodonium three-component photoinitiating system. When combined with benzoyl peroxide (BPO), these systems are active in photoinduced redox polymerization; i.e., the CTC is used to absorb the light and generates initiating radicals and the amine/BPO couple allows a redox polymerization. Therefore, a fast/slow time control of the radical reaction is feasible under air, and an excellent monomer conversion is obtained both at the top layer and in the core of the sample. The efficiency of this photoactivated redox system is assessed in terms of monomer conversion (followed by FTIR and RAMAN analysis) and time control. The chemical mechanisms are studied using UV-vis absorption spectroscopy, steady-state photolysis, 31P NMR, and ESR-spin trapping experiments.

Vol. 49(17), pp. 6296-6309 
article DOI URL 
Abstract: Efficient redox initiating systems for radical polymerizations under air usually show some severe drawbacks such as handling and toxicity of the oxidizing agent (peroxides, persulfates, peroxidiphosphates, disulfides, etc.), toxicity of the reducing agent (aromatic amines such as 4-N,N-trimethylaniline), and more generally a low top surface conversion due to high oxygen inhibition. The originality of the proposed paper relies on the development of new redox initiating systems for the polymerization of (meth)acrylate monomers that does not contain any hazardous compound (no peroxide) and is amine-free (low toxicology issues). And these new systems that possess the advantages of redox-initiated polymerization (possibility to cure thick samples) can also be photoactivated in order to have a faster and better curing of the surface of the sample (advantages of the photopolymerization to overcome the oxygen inhibition). The light activations presented in this work have been done with light-emitting diodes (LEDs) as they have a low energy consumption and are safer to the user than UV light. Two wavelengths have been used: 405 nm (in the blue range of the spectrum) and 780 nm (in the near-infrared) showing the versatility of these new photo/redox initiating systems. In particular, the reactivity in the near-IR (not related to any heating of the sample) is a very original result. In addition with the presentation of the performance of the new systems in polymerization and photoactivated polymerization, a full analysis of the chemical mechanisms and species involved has been performed. Remarkably, the new proposed Cu(acac)2/2dppba system is also able to overcome the oxygen inhibition for free radical redox (photo)polymerization. © 2016 American Chemical Society.

Abstract: Abstract In this study, copper oxide (CuO) has been dispersed into an organized mesoporous silica (SBA-15) using the solid state grinding method. The resulting CuO/SBA-15 materials were evaluated as SOx adsorbents and were fully characterized before and after sulfation. The influence of the calcination conditions on the copper dispersion was studied. Results show that the textural properties of the materials and the formed copper species are closely related to the calcination procedure. The adsorption performances increase with the copper dispersion. It was found that despite the high GHSV value used in this work (25,000 h−1), the highly dispersed copper species confer a high efficiency to the adsorbent. Cyclic adsorption/regeneration experiments show a surprising but explainable increase in the adsorption efficiency in the second cycle followed by a slight but monotonic deactivation in the subsequent cycles, as a result of the progressive sintering of the copper species.

Abstract: In the present work, organized mesoporous SBA-15 and amorphous Aerosil 380 silicas were modified by copper incorporation through wet impregnation of copper nitrate to obtain SOx regenerable adsorbents. Impregnation, drying and calcination conditions were carefully controlled in order to obtain highly dispersed Cu2+ species assumed to be Cu-O-Si species. Materials were evaluated as SOx adsorbents through multicycle adsorption/regeneration experiments and were fully characterized before and after sulfation by XRD (X-Ray Diffraction), XRF (X-Ray Fluorescence), SEM (Scanning Electron Microscopy) and TEM (Transmission Electron Microscopy) analyses. The influence of the nature of the support and of the copper loading on the adsorbent behavior was studied. Results show that the adsorbent performances in SOx trapping along multicycle operations depend on both the copper loading and the nature of the silica support. The characterizations of the aged adsorbents suggest that their deactivation along multicycle operations is due to the copper species sintering. Results show that there is an optimal copper loading for a maximal SOx adsorption efficiency. (C) 2016 Elsevier B.V. All rights reserved.

Vol. 223, pp. 79-88 
article URL 
Abstract: Abstract The synthesis of mesoporous carbon with confined PdCo nanoalloy particles by a one-pot soft-template approach is reported herein. The influence of metal precursor type, metal composition and annealing temperature on the carbon@PdCo material characteristics was systematically investigated. Small and homogeneously distributed PdCo nanoparticles in the carbon matrix were achieved. The PdCo particle size could be tuned from 8 to 25 nm and the metal composition proved to be the main parameter controlling the size. When the amount of Pd is low (Pd50Co50) the particle is small and increases with the increase of temperature. On the contrary, for richer Pd contents (Pd75Co25, Pd90Co10) the particle size is larger but they exhibit extremely high stability with no obvious modification of size between 450 and 800 °C. The tuned experimental parameters had less impact on the materials textural characteristics, they exhibit similar surface area and uniform pore size distribution. Among the materials, only the Pd rich alloys (Pd90Co10) are able to form metallic hydride and consequently, showing the highest hydrogen adsorption capacity.

Abstract: Nanothermites, combining a fuel with an oxidizer at the nanoscale, represent a class of energetic material that has been attracting increasing attention over the past decade. This intensive interest is due to their tuneable pyrotechnic performance, making the materials promising candidates for ordnance applications. However, the extreme mechanical and electrostatic sensitivities of energetic composites make handling them hazardous. In this study, a realistic desensitization method is suggested via the addition of polyaniline while maintaining an interesting combustion velocity in contrast to the literature values. This investigation claims a major scientific breakthrough in the preparation of safer energetic nanocomposites. © 2016 Taylor & Francis

Vol. -(-), pp. - 
article DOI URL 
Abstract: A new photoinitiator based on a bis-silylketone (BSK) structure is proposed as a novel compound leading to highly efficient initiating silyl radicals for the polymerization of methacrylates (e.g., a bisphenol A-glycidyl methacrylate/triethyleneglycol dimethacrylate blend (70%/30% w/w)) upon exposure to a blue light emitting diode and a green laser diode. The polymerization profiles are recorded by real time Fourier transform IR (FTIR) spectroscopy. Absorption, fluorescence, electron spin resonance (ESR), and steady state experiments are used to investigate the involved chemical mechanisms. Molecular orbital calculations are also carried out. Remarkably, BSK efficiently works in the presence of an iodonium salt. The overall mechanism for the initiation step is clarified. This novel class of silyl radical generating photoinitiators is really promising for the photopolymerization of methacrylates, e.g., in dental materials. © 2016 WILEY-VCH Verlag GmbH & Co.

Guizani, C., Haddad, K., Jeguirim, M., Colin, B. and Limousy, L. Combustion characteristics and kinetics of torrefied olive pomace 2016 Energy
Vol. 107, pp. 453-463 
article DOI  
Abstract: This investigation aims to examine the OP (olive pomace) recovery as a fuel in heat production systems. A two-steps process is proposed to adapt OP for such application. Firstly, the OP torrefaction is performed for various temperatures in order to improve the combustion properties. It is seen that, in addition to the hydrophobic character, the higher heating value of the samples increased with the torrefaction severity. Secondly, the reactivity in air of TOP (torrefied olive pomace) using thermogravimetric analyses is examined. The results show a decrease in the TOP reactivity with the increase of the torrefaction temperature. This behaviour is attributed to the degraded proportion of the three macro-components: Hemicellulose (HC), Cellulose (C), Lignin (L). A kinetic model based on the HC, C and L thermal degradation is applied to simulate the combustion of OP and TOP samples. The activation energies of the macro-components degradation and char combustion reactions are determined. In addition, the proportions of HC, C and L left in the TOP samples after the torrefaction step are extracted. This modelling part brings understanding keys on both torrefaction and combustion steps. It also provides kinetic parameters concerning OP and TOP combustion, which are necessary for combustor sizing. (C) 2016 Elsevier Ltd. All rights reserved.

Vol. 112, pp. 133-145 
article DOI URL 
Abstract: The present study aims to understand the phenomenology of char gasification by monitoring the chemical, structural and textural char characteristics through the gasification reaction. Chars from beech wood were gasified under 20%H2O, 20%CO2 and 20%H2O + 20%CO2 in N2 at 900° C. The gasification reactions were stopped at 20%, 50% and 70% of char conversion. The char properties were analysed by different analytical techniques such as temperature programmed desorption coupled to mass spectrometry, Raman spectroscopy, Scanning Electron Microscopy, N2 manometry and X-ray Fluorescence. These analyses provide valuable information on the unfolding of the gasification reactions with H2O, CO2 and their mixtures. In particular, it is noted that H2O and CO2 gasification reactions follow different pathways. Moreover, during mixed atmosphere, despite that the char reactivity can be fairly expressed by summing the two individual reactivities, this apparent additivity appears to be the result of several competitions and synergies between H2O and CO2 reactions. © 2016 Elsevier Ltd.

Vol. 36(2), pp. 627-650 
article DOI URL 
Abstract: Surface modification studies of non-vulcanized BR elastomers (butadiene rubber) by low-pressure air plasma treatment and the effect on ageing and adhesion performances are presented in this paper. In particular, the influence of discharge power and distance from the glow discharge, and impact of antioxidant molecules in the BR formulation were examined. To characterize the changes to the BR surface, XPS spectroscopy, contact angle measurements, AFM nanoindentation experiments and tack measurements were utilized. Oxidation and crosslinking were the main mechanisms observed on the polymer chains regardless of the plasma conditions used. Beyond a certain threshold of plasma energy (in our case, discharge power of  60 W and exposure time of  30 s), a steady state was reached irrespective of the distance from the glow discharge. The presence of antioxidant molecules considerably reduced crosslinking phenomena while maintaining oxidation processes on polymer chains and increasing the nitrogen content in the near surface region. The mechanisms responsible for these differences have been identified. Interestingly, the COOH/C=O ratio changed according to the balance between oxidation and crosslinking. The hydrophobic recovery rate was mainly driven by temperature-dependent dynamics and varied according to the degree of crosslinking in the surface region. It was found to be lower in air atmosphere in the presence of antioxidant molecules. Finally, the presence of antioxidant molecules in the BR formulation allowed the adhesion performances after plasma exposure to significantly increase. © 2015, Springer Science+Business Media New York.

Vol. 81, pp. 674-685

Abstract: In this manuscript, we report on the phase behavior of a novel family of ionic liquid crystals based on wedge-shaped amphiphilic mesogens of benzene sulfonates with different counterions (Li, Na, K and Cs) and polymerizable acrylic groups in the alkyl chain periphery. The phase diagrams of these compounds were explored with differential scanning calorimetry, polarized optical microscopy and temperature-dependent small-angle X-ray scattering. Lamellar and columnar liquid-crystalline phases were identified. Ionic conductivity was measured by impedance spectroscopy at different relative humidities. The influence of the counterion on the mesostructure and electrical conductivity is further discussed. Finally, it is demonstrated how photopolymerization can be employed to arrest the different supramolecular structures and transform the low-molecular-weight nanostructured liquid into self-standing ion conducting polymer membranes. © 2016 Elsevier Ltd

Vol. 16(9), pp. 4897-4904 
article DOI URL 
Abstract: The development of an original and simple procedure of hydrothermal porous biosourced zinc phosphates synthesis from casein protein is reported in this study. The synthesis procedure does not require additional phosphorus source and structure-directing agent for macroporosity formation. The formation of zinc phosphates has been investigated as a function of the pH of the starting mixture (4.5-14.0) and of the temperature of calcination (from 150 to 750 °C). A material composed of hopeite (Zn3(PO4)2·4H2O) and casein was obtained after synthesis at pH 4.5 and 100 °C from a mixture of casein and zinc nitrate solutions. Macroporous zinc phosphates composed of α-Zn3(PO4)2 and α-Zn2P2O7 with large porous size distribution (pore diameter between 350 to 1000 nm) were successfully obtained after the complete casein decomposition at 750 °C. Samples were characterized by X-ray powder diffraction, solid-state 31P NMR spectroscopy, thermal analysis, scanning electron microscopy, nitrogen adsorption, and by fluorescence spectroscopy. The macroporous zinc phosphates have a good stability in water for at least 24 h with no detectable change in their structure, porosity, and crystal morphology. © 2016 American Chemical Society.

Vol. 32(31), pp. 7765-7773 
article DOI URL 
Abstract: We have considered in this work the Wilhelmy plate tensiometer to characterize the wetting properties of two model surface textures: (i) a series of three superhydrophobic micropillared surfaces and (ii) a series of two highly water-repellent surfaces microtextured with a femtosecond laser. The wetting forces obtained on these surfaces with the Wilhelmy plate technique were compared to the contact angles of water droplets measured with the sessile drop technique and to the bouncing behavior of water droplets recorded at a high frame rate. We showed that it is possible with this technique to directly measure triple-line anchoring forces that are not accessible with the commonly used sessile drop technique. In addition, we have demonstrated on the basis of the bouncing drop experiments wetting transitions induced by the specific test conditions associated with the Wilhelmy plate tensiometer for the two series of textured surfaces. Finally, the tensiometer technique is proposed as an alternative test for characterizing the wetting properties of highly liquid-repellent surface, especially under immersion conditions. © 2016 American Chemical Society.

Vol. 497(1-2), pp. 54-61 
article DOI  
Abstract: The purpose of this study is to evaluate the potential of simple high performance liquid chromatography (HPLC) setup for quantification of adsorbed proteins on various type of plane substrates with limited area (< 3 cm(2)). Protein quantification was investigated with a liquid chromatography chain equipped with a size exclusion column or a reversed-phase column. By evaluating the validation of the method according to guidelines of the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), all the results obtained by HPLC were reliable. By simple adsorption test at the contact of hydrophilic (glass) and hydrophobic (polydimethylsiloxane: PDMS) surfaces, kinetics of adsorption were determined and amounts of adsorbed bovine serum albumin, myoglobin and lysozyme were obtained: as expected for each protein, the amount adsorbed at the plateau on glass (between 0.15 mg/cm(2) and 0.4 mg/cm(2)) is lower than for hydrophobic PDMS surfaces (between 0.45 mg/cm(2) and 0.8 mg/cm(2)). These results were consistent with bicinchoninic acid protein determination. According to ICH guidelines, both Reversed Phase and Size Exclusion HPLC can be validated for quantification of adsorbed protein. However, we consider the size exclusion approach more interesting in this field because additional informations can be obtained for aggregative proteins. Indeed, monomer, dimer and oligomer of bovine serum albumin (BSA) were observed in the chromatogram. On increasing the temperature, we found a decrease of peak intensity of bovine serum albumin as well as the fraction of dimer and oligomer after contact with PDMS and glass surface. As the surface can act as a denaturation parameter, these informations can have a huge impact on the elucidation of the interfacial behavior of protein and in particular for aggregation processes in pharmaceutical applications.

Vol. 19(4), pp. 496-504 
article DOI URL 
Abstract: Porous flat ceramic-metal composite (Cermet) membrane supports were elaborated from kaolin and aluminum powder mixtures by the press drying-sintering process. The evolution of structure and surface properties was followed by water permeation, tensile strength, mercury porosimetry, surface charge and contact angle measurements. These characterizations have demonstrated that the addition of aluminum to the kaolin matrix has a beneficial effect on the membrane support properties. In particular, the water permeability and mechanical strength increased gradually in the presence of aluminum. In addition, the hydrophilicity of the cermet supports was found to increase gradually with the aluminum load. However, the surface charge was not affected by the aluminum introduced into the cermet composition. Filtration experiments were carried out with the support containing 4% wt of aluminum. The results have indicated that this support could be used to purify dye-containing water. © 2015 Académie des sciences. Published by Elsevier Masson SAS. All rights reserved.

Abstract: Abstract The chemical modification of tannin through epoxidation is a way to develop new applications for tannins and to improve tannin resins performances. In this paper the influence of reaction conditions was studied. Commercial tannin bark extract was epoxidized. The resulting products were characterized by FT-IR Spectroscopy, 13C NMR and MALDI-TOF mass spectrometry. Tannin epoxidation has been confirmed by 13C NMR and FT-MIR. Wood specimens were bonded with mixed diglycidyl ether of bisphenol A (DGEBA) and glycidyl ether tannin (GET) epoxy resin formulations. The bonded joints were tested for block shear strength. The results obtained indicated that such formulations, based on up to 75% commercial natural materials are capable of satisfying the shear strength requirements of relevant international standards.

Abstract: Radical step-growth photopolymerization of dithiol diene monomer miniemulsion is shown to be a highly efficient, robust, and versatile route to generate film-forming linear poly(thioether) latexes. At extremely fast rates, the process results in high-molecular-weight polysulfide products, exhibiting both semicrystalline and oxidation-responsive properties. Four key issues are addressed as regards the practical implementation of this novel UV-driven waterborne technology: the preparation of a photolatent and colloidally stable thiol-ene monomer miniemulsion, the identification of key experimental parameters controlling reaction kinetics and polymer microstructure, the characterization of film semicrystallinity, and the application of poly(thioether ester) latexes as dual-stimuli-responsive nanocarriers sensitive to both oxidation and hydrolysis.

Abstract: An efficient strategy for comprehensive utilization of the conjugated sulfonium salt photoacid generator (PAG), namely, 3-4-[4-(4-N, N'-diphenylamino)-styryl]phenyl phenyl dimethyl sulfonium hexafluoroantimonate, was developed through photoinitiated cationic photopolymerization (CP) of epoxides and vinyl ether upon exposure to near-UV and visible light-emitting diodes (LEDs; e.g., 365, 385, 405, and 425 nm). Photochemical mechanisms were investigated by UV-vis spectra, molecular orbital calculations, fluorescence, cyclic voltammetry, and electron spin resonance spintrapping analyses. Compared with commercial PAGs, the prepared conjugated sulfonium salt generated H+, which can be used as photoinitiator. Moreover, the fluorescent by products from photodecomposition can be used as photosensitizer of commercial iodonium salt in the photoinitiating systems of CP. These novel D-pi-A type sulfonium-based photoinitiating systems are efficient (epoxide conversion =85-90% and vinyl conversion >90%; LEDs upon exposure to 365-425 nm) even in low-concentration initiators (1%, w/w) and low curing light intensities (10-40 mW cm(-2)).

Vol. 22(29), pp. 10127-10135 
article URL 
Abstract: Micrometer-sized hierarchical Sn3O2(OH)2 octahedra, which are self-assembled one inside the other, resembling “Russian doll” organization, have been obtained by a metalorganic approach. This synthesis is based on the controlled hydrolysis of [Sn(NMe2)2]2 in the presence of an alkylamine ligand in an organic solvent (THF). The water content of the medium proved to be a key parameter for the formation of these multi-walled octahedra. The resultant structures have been used as gas-sensitive layers on micromachined silicon devices. During in situ heating, Sn3O2(OH)2 is oxidized to SnO2 while retaining the initial morphology. The sensors present outstanding dynamic responses at very low CO concentrations (7 % and 67 % resistance variation to 0.25 and 20 ppm CO, respectively, at an operating temperature of 500 °C). This superior gas-sensing performance is closely related to the unique microstructure of the SnO2 multi-walled octahedra.

Vol. 120(5), pp. 2688-2697 
article DOI  
Abstract: The influence of the morphology (microcrystals, nanocrystals, nanosponges and nanosheets) of MFI and *BEA-type zeolites on their adsorption capacities and adsorption rate of n-hexane at 25 degrees C has been investigated. The capacity of n-hexane adsorption sensitive to micro- and mesopore volume is enhanced by the use of zeolite nanocrystals or hierarchical nanoporous materials (nanosheets and nanosponges). In the case of hierarchical zeolites MFI and *BEA nanosponges, the n-hexane adsorption capacities reached values of about 790 and 693 mg/g, respectively, that are much higher than those in the corresponding microcrystals (130 and 103 mg/g, respectively). On the opposite the kinetics of n-hexane adsorption are slower in nanocrystals and hierarchical zeolites compared to big crystals, due to the lower crystallinity of the zeolitic material and the nature of the probe molecule.

Vol. 58, pp. 111-114 
article DOI URL 
Abstract: The impact of crystal size on the transition orthorhombic ↔ monoclinic phase in MFI-type purely silica zeolites is investigated between 293 and 473 K using 29Si MAS NMR and powder X-ray diffraction. Three silicalite-1 zeolites are synthesized: a material constituted of micron-sized crystals, pseudospherical nanometer-sized crystals and hierarchical porous zeolites with a mesoporous network created by the use of a gemini-type diquaternary ammonium surfactant giving nanosheet zeolites. Our results show for the first time that the orthorhombic ↔ monoclinic phase transition already known for micron-sized particles also occurs in nanometer-sized zeolite crystals whereas our data suggest that the extreme downsizing of the zeolite crystal to one unit cell in thickness leads to an extinction of the phase transition. © 2016 Elsevier Masson SAS

Abstract: [3]-Radialene-based dopant CN6-CP studied herein, with its reduction potential of +0.8 versus Fc/Fc+ and the lowest unoccupied molecular orbital level of -5.87 eV, is the strongest molecular p-dopant reported in the open literature, so far. The efficient p-doping of the donor-acceptor dithienyl-diketopyrrolopyrrole-based copolymer having the highest unoccupied molecular orbital level of -5.49 eV is achieved. The doped films exhibit electrical conductivities up to 70 S cm(-1).

Vol. 45(10), pp. 4392-4400 
article DOI URL 
Abstract: The energetic performances of seven SOD or RHO-topology ZIFs, with zinc or cobalt metal cation (ZIF-8, ZIF-90, Zn(dcim)2-SALE, ZIF-67, ZIF-7, ZIF-71, ZIF-11) were evaluated using water intrusion-extrusion under high pressure. The relationship between the structural parameters (in particular the pore system SOD or RHO, the type of linker, the metal cation nature) and the intrusion pressure was studied to better understand the mechanism of water intrusion and the energetic behaviour for a given ZIF crystal type. "ZIF-8-water", "ZIF-67-water" and "ZIF-71-water" systems display a shock-absorber behaviour. A very important hysteresis for ZIF-71 and a slight difference between the first intrusion-extrusion cycle and the following ones for ZIF-67 were observed. ZIF-8 (SOD) with zinc cation and ZIF-67 (SOD) with cobalt cation display similar intrusion pressures. For ZIF-71 (RHO) material, the stored energy is more than doubled compared to ZIF-8 and ZIF-67 (SOD). This might be related to the topology. No water intrusion was observed after three water intrusion-extrusion cycles, for the ZIF-90 (SOD), Zn(dcim)2-SALE (SOD), ZIF-7 (SOD) and ZIF-11 (RHO) materials. This is explained in term of hydrophilic feature as well as topology and linker effects. © The Royal Society of Chemistry 2016.

Vol. 4(3), pp. 22 
article DOI  
Abstract: Nanocomposites of ordered mesoporous carbon associated with chromium nitride (CrN) or vanadium nitride (VN) nanoparticles were obtained by a simple one-pot synthesis based on the solvent evaporation induced self-assembly (EISA) process using Pluronic triblock surfactant as soft-template and a phenol-based resin (resol) as carbon precursor. These nanocomposites were characterized by X-ray diffraction, nitrogen physisorption and Transmission Electron Microscopy (TEM) techniques. Electron tomography (or 3D-TEM) technique was particularly useful for providing direct insight on the internal architecture of C/CrN nanocomposite. Nanocomposites showed a very well organized hexagonal mesoporous carbon structure and a relatively high concentration of nanoparticles well distributed in the porous network. The chromium and vanadium nitrides/mesoporous carbon nanocomposites could have many potential applications in catalysis, Li-ion batteries, and supercapacitors.

Kraiem, N., Lajili, M., Limousy, L., Said, R. and Jeguirim, M. Energy recovery from Tunisian agri-food wastes: Evaluation of combustion performance and emissions characteristics of green pellets prepared from tomato residues and grape marc 2016 Energy
Vol. 107, pp. 409-418 
article DOI  
Abstract: In Tunisia, seasonal and centralized discharges of tomato waste and grape marc generated from agri-food industries have negative effects on the environment. Characterization of these residues shows that their calorific values are suitable for their energy recovery. However, the high mineral contents and the low bulk densities limit their direct use as biofuel. Therefore, a blending process using sawdust followed by densification into pellets is proposed for the recovery of these agri-food residues. Such strategy allows the pellets to meet standard requirements of the biofuels market. Furthermore, the performance of the pellets is evaluated during combustion tests in domestic boiler. The combustion parameters, the gaseous and particulate matter emissions are analyzed. Results indicate that the pellets prepared from agri-food residues have boiler and combustion efficiencies comparable to wood pellets. However, gaseous and particulate emissions are strongly affected by the operating parameters of the domestic boilers. Therefore, these parameters such as mass flow of water in the heat exchanger, combustible mass flow, primary and secondary inlet air flow should be adapted to each agri-food residue to benefit from these resources without leading to negative environmental impacts.

Labaki, M. and Jeguirim, M. Thermochemical conversion of waste tyres—a review 2016 Environmental Science and Pollution Research
Vol. -(-), pp. 1-31 
article DOI URL 
Abstract: A review of the energy recovery from waste tyres is presented and focuses on the three thermochemical processes used to valorise waste tyres: pyrolysis, gasification, and combustion/incineration. After recalling the chemical composition of tyres, the thermogravimetric behaviours of tyres or their components under different atmospheres are described. Different kinetic studies on the thermochemical processes are treated. Then, the three processes were investigated, with a particular attention given to the gasification, due to the information unavailability on this process. Pyrolysis is a thermochemical conversion to produce a hydrocarbon rich gas mixture, condensable liquids or tars, and a carbon-rich solid residue. Gasification is a form of pyrolysis, carried out at higher temperatures and under given atmosphere (air, steam, oxygen, carbon dioxide, etc.) in order to yield mainly low molecular weight gaseous products. Combustion is a process that needs a fuel and an oxidizer with an ignition system to produce heat and/or steam. The effects of various process parameters such as temperature, heating rate, residence time, catalyst addition, etc. on the energy efficiency and the products yields and characteristics are mainly reviewed. These thermochemical processes are considered to be the more attractive and practicable methods for recovering energy and material from waste tyres. For the future, they are the main promising issue to treat and valorise used tyres. However, efforts should be done in developing more efficient technical systems. © 2016 Springer-Verlag Berlin Heidelberg

Abstract: Abstract By using biosourced raw materials such as condensed tannins and furfuryl alcohol a biosourced thermoset resin was developed and used and tested for a new application: as a resin matrix of automotive brake pads. The manufacturing procedure developed is particularly easy. Automotive brake pads based on this green resin were characterized and showed excellent braking properties and wear resistance when used under real car, full scale test conditions. Their mechanical resistance was found to be comparable to that of commercial automotive brake pads bonded with synthetic phenolic resins. They tolerated well the severe stresses induced by a strong braking like an emergency braking: 50 km/h (31 mph) until complete standstill and showed braking distances comparable or shorter than commercial brake pads.

Vol. 88, pp. 36-43 
article DOI  
Abstract: Thymus satureioides is one of the most produced and consumed aromatic herb in Morocco. Hence, it is crucial to control its moisture content during storage. The aim of this research work was to compare the effect of thyme preservation methods on adsorption at different temperatures (30, 40 and 50 degrees C) and relative humidity (5-90%). For that, saturated salt solutions method was used. The behavior of untreated, irradiated and treated thyme during storage was studied by the experimental determination of adsorption isotherm curves. Then, the experimental data of adsorption were investigated and described by four mathematical models. Adsorption capacity of thyme decreases with the temperature rise, at constant relative humidity. The empirical Peleg model was found to best represent the treated thyme. However, untreated and irradiated thyme were approached by the Enderby's model. Hence, treatments by thermal -biochemical process and irradiation had significant effects on adsorption, optimum water activity and physical properties of thyme. (C) 2016 Elsevier B.V.

Vol. -(-), pp. - 
article DOI URL 
Abstract: Complementary analytical methods have been used to study the effect of potassium on the pyrolysis mechanisms of cellulose and lignocellulosic biomasses. Thermogravimetry, calorimetry, high-temperature 1HNMR spectroscopy (insitu and real-time analysis of the fluid phase formed during pyrolysis), and water extraction of quenched char followed by size-exclusion chromatography coupled with mass spectrometry have been combined. Potassium impregnated in cellulose suppresses the formation of anhydrosugars, reduces the formation of mobile protons, and gives rise to a mainly exothermic signal. The evolution of mobile protons formed from K-impregnated cellulose has a very similar pattern to the evolution of the mass loss rate. This methodology has been also applied to analyze miscanthus, demineralized miscanthus, miscanthus re-impregnated with potassium after demineralization, raw oak, and Douglas fir. Hydrogen mobility and transfer are of high importance in the mechanisms of biomass pyrolysis. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Vol. 108, pp. 165-177 
article DOI  
Abstract: Char is produced during pyrolysis of biomass and it could be valorised as soil amendment, activated carbon or to produce syngas or heat by further oxidation. The mechanisms of biochars formation have to be better understood in order to tailor their properties. For this purpose, the pyrolysis of biomass was conducted in a fixed bed reactor allowing a good control of pyrolysis conditions. Miscanthus and the macromolecules extracted from this same biomass (holocellulose, cellulose, ethanol organosolv lignin) were pyrolysed to various final temperatures (200-500 degrees C). The chemical moieties formed in the chars were studied by solid state C-13 NMR. A Cross Polarization method at the Magic Angle Spinning with Adiabatic Passage though Hartmann-Hahn conditions (CP/MAS APHH) has been found to give similar spectra than the Direct Polarization quantitative method in much shorter acquisition times. A quantitative study on the formation of aromatic structures in the network of the macromolecules in miscanthus and in the fractionated macromolecules was conducted. It is shown that below 300 degrees C xylan is the main source of aromatic formation while above this temperature the aromatization of cellulose occurs. The interactions between lignin and carbohydrates inside the network of biomass for aromatic structures formation are discussed. (C) 2016 Elsevier Ltd. All rights reserved.

Abstract: Two cationic iridium (III) complexes [Ir(dfppy)(tpy)(bpy)](PF6) and [Ir(dfppy)(tpy)(phen)](PF6) bearing three different ligands were tested as triplet emitters for Light-Emitting Electrochemical Cells (LECs). These two phosphorescent materials only constitute the third and fourth examples of triple heteroleptic cationic iridium complexes to be tested in electroluminescent devices. LECs fabricated with this almost unknown class of iridium complex furnished green-emitting devices. Parallel to investigations devoted to electroluminescent properties, photophysical and electrochemical properties of the two new complexes were examined. Density functional theory calculations were also performed to provide insight into the electronic structure of the two emitters. © 2016 Elsevier B.V. All rights reserved.

Vol. 6, pp. 19719-19719 
article  
Abstract: The functionalization of graphene remains an important challenge for numerous applications expected by this fascinating material. To keep advantageous properties of graphene after modification or functionalization of its structure, local approaches are a promising road. A novel technique is reported here that allows precise site-selective fluorination of graphene. The basic idea of this approach consists in the local radicalization of graphene by focused ion beam (FIB) irradiation and simultaneous introduction of XeF2 gas. A systematic series of experiments were carried out to outline the relation between inserted defect creation and the fluorination process. Based on a subsequent X-ray photoelectron spectroscopy (XPS) analysis, a 6-fold increase of the fluorine concentration on graphene under simultaneous irradiation was observed when compared to fluorination under normal conditions. The fluorine atoms are predominately localized at the defects as indicated from scanning tunneling microscopy (STM). The experimental findings are confirmed by density functional theory which predicts a strong increase of the binding energy of fluorine atoms when bound to the defect sites. The developed technique allows for local fluorination of graphene without using resists and has potential to be a general enabler of site-selective functionalization of graphene using a wide range of gases.

Vol. 100, pp. 337-344 
article DOI URL 
Abstract: We investigate the nitrogen doping of mono- and bi-layer graphene on 6H-SiC(0001) using two plasma-based methods: a lab-scale microwave plasma gun and an industrial-scale plasma-based implanter. As revealed by X-ray photoemission spectroscopy, the thickness of the pristine graphene significantly influences the bonding configuration of the incorporated nitrogen atoms. Using the plasma gun, a high concentration of graphitic-nitrogen (3 at%) is obtained in N-doped bilayer graphene, while only 0.2 at% of pyridinic-nitrogen is incorporated. By contrast, a comparable amount of each nitrogen doping configuration is found with monolayer graphene. The integrity of the bilayer graphene is also better preserved than its monolayer counterpart after nitrogen plasma exposure, as evidenced by their inverse photoemission spectra. It is attributed to a better stability and a lower vacancy creation rate in bilayer graphene during plasma exposure. In addition, the N-doped bilayer graphene shows an efficient n-type doping, with a Dirac point brought 0.45 ± 0.1 eV away from the Fermi energy. In brief, this study reports an efficient method for tailoring the electronic properties of graphene using industry-suited techniques, thereby promoting future graphene-based applications. © 2015 Elsevier Ltd.

Vol. 217(20), pp. 2321-2329 
article DOI URL 
Abstract: Two high surface area titania forms, dispersed as stable nanoparticles or coated on fused silica microfiber, are used as nonleachable photocatalysts for the radical photopolymerization of methyl methacrylate miniemulsion in water. At low loading (0.17 wt%/wtmonomer), both nanoscale TiO2 yield ≈50% conversion after 10 min UV irradiation, compared to 63% with a conventional type I photoinitiatior (hydroxyacetophenone). High-molecular-weight values (&gt;180 kDa) and a polydispersity index of about 1.5 are achieved, indicating that undesirable degradation is negligible. In the proposed mechanism, a surface initiation takes place through the generation of hydroxyl radicals from H2O oxidation. It is shown that irradiance and TiO2 content are two key parameters for controlling molecular weight and conversion values. The supported TiO2 form can be easily recovered and reused up to four times, despite a gradual reduction in conversion. Deposited on the wall of the annular photochemical reactor, it enables reaction scaling-up. (Figure presented.). © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Vol. 18(17), pp. 4714-4724 
article DOI URL 
Abstract: A completely eco-compatible halogenation reaction of arenes has been developed allowing high conversions (&gt;95%) of iodobenzene with nearly 100 kg iodobenzene converted per kgcat in one day. Several solid acids, zeolites being the most promising, have been successfully tested in the chlorination reaction of iodobenzene by using trichloroisocyanuric acid (TCCA), a green chlorination agent. H-∗BEA zeolites were found to be the most active catalysts for this model halogenation reaction. A strong structure-activity relationship could be established by thorough characterisation (SEM, BET, XRD, FTIR) of various synthetic zeolites. Indeed, nano-sized ∗BEA zeolites and more specifically nanosponge-like ∗BEA crystals exhibited the highest catalytic performance with a conversion up to 100% and a selectivity toward monochlorinated products up to 98%. Finally, the gained knowledge was applied to set-up an eco-compatible continuous flow halogenation process of different aromatics catalysed by H-∗BEA zeolites. © 2016 The Royal Society of Chemistry.

Cation Migration and Structural Deformations upon Dehydration of Nickel-Exchanged NaY Zeolite: A Combined Neutron Diffraction and Monte Carlo Study 2016 Journal of Physical Chemistry C
Vol. 120(32), pp. 18115-18125 
article DOI URL 
Abstract: Combining neutron diffraction and classical molecular simulations, we describe the cation migration and associated structural changes taking place in a Ni-exchanged NaY faujasite zeolite upon stepwise dehydration from room temperature up to 400 °C. The cation redistribution between sites and the related framework deformations taking place upon water removal are identified and quantified. Neutron diffraction allows monitoring the zeolite structure, the average cation location and the water content, whereas molecular modeling provides insights into the correlations between the positions of cations and water molecules. Importantly, we demonstrate that the migration of Ni2+ toward highly confined sites upon dehydration is the driving force behind deformation of the hexagonal prisms. The present work illustrates the relevance of combining these two experimental and theoretical approaches to clarify the complex interplay between cation hydration, cation location, and framework deformation. It also underlines the importance to capture the flexibility of the framework in molecular simulation of hydrated zeolite in particular when multivalent ions are involved. © 2016 American Chemical Society.

Vol. 19(4), pp. 466-474 
article DOI URL 
Abstract: An optimized model is developed for the production of bio-fuels from biomass using a SuperPro Designer tool. Four types of Tunisian biomass feedstocks including date palm rachis, olive stones, vine stems and almond shells were selected for the fast pyrolysis process simulation. Simulation tests were performed at different temperatures ranging from 450 to 650 °C, and residence times ranging from 0.1 to 10 s and the products yield were determined. The obtained results indicate that a temperature of 575 °C and 0.25 s vapor residence time are the optimum parameters to maximize the bio-oil yield. Comparison between the different feedstocks indicates that a higher bio-oil fraction was obtained from the date palm rachis and vine stem. However, the difference between the samples is not significant and further investigations on the bio-oil properties are requested to select the suitable biomass for bio-oil production in Tunisia. © 2016 Académie des sciences.

Vol. 61, pp. 57-65 
article DOI  
Abstract: Water- mediated modifications in chitosan films were investigated from both molecular mobility and structure perspectives. Chitosan films, prepared by the solvent casting method in acetic acid medium, were exposed to relative humidity ranging from 11% to 92% at 25 degrees C. This work reveals that chitosan film exhibits a different structure below and above a water content of around 15% (w/w wet basis). A marked increase in mobility was evidenced at this point from proton relaxation and paramagnetic probe rotational mobility. The influence of such mobility modification was further studied by differential scanning calorimetry but no classical plasticizing effect of the water on the glass transition of chitosan was detected. The same singular point was observed when the water content increased, but no regular decrease of the Tg values was noticed. However, after heating above 80 degrees C, the polymer film lost its initial characteristics, consecutively to acetic acid release and structural reorganization of the polymer network. It gave rise to the presence in such chitosan films of two distinct amorphous domains associated to a wide change in the baseline due to the glass transition phenomenon. Such instability originates from heterogeneities at the molecular scale. (C) 2016 Elsevier Ltd. All rights reserved.

Vol. 6(6), pp. 065312 
article DOI  
Abstract: Absorbance-Modulation-Optical Lithography (AMOL) has been previously demonstrated to be able to confine light to deep sub-wavelength dimensions and thereby, enable patterning of features beyond the diffraction limit. In AMOL, a thin photochromic layer that converts between two states via light exposure is placed on top of the photoresist layer. The long wavelength photons render the photochromic layer opaque, while the short-wavelength photons render it transparent. By simultaneously illuminating a ring-shaped spot at the long wavelength and a round spot at the short wavelength, the photochromic layer transmits only a highly confined beam at the short wavelength, which then exposes the underlying photoresist. Many photochromic molecules suffer from a giant mismatch in quantum yields for the opposing reactions such that the reaction initiated by the absorption of the short-wavelength photon is orders of magnitude more efficient than that initiated by the absorption of the long-wavelength photon. As a result, large intensities in the ring-shaped spot are required for deep sub-wavelength nanopatterning. In this article, we overcome this problem by using the long-wavelength photons to expose the photoresist, and the short-wavelength photons to confine the "exposing" beam. Thereby, we demonstrate the patterning of features as thin as lambda/4.7 (137nm for lambda = 647nm) using extremely low intensities (4-30 W/m(2), which is 34 times lower than that required in conventional AMOL). We further apply a rigorous model to explain our experiments and discuss the scope of the reverse-AMOL process. (C) 2016 Author(s).

Vol. 5(2), pp. 163-167 
article DOI URL 
Abstract: We demonstrate specific interface-templated crystallization behavior of biocompatible amphiphilic poly(ethylene oxide)-b-poly(μ-caprolactone) (PEO-b-PCL) block copolymers enabling triggered shaping of the curvature of the oil/water interface and controlled phase inversion, including the formation of stable multiple emulsions. Water-born anisotropic micelles of PEO-b-PCL block copolymers self-assemble at the oil-water interface in a multilayer form and undergo conformational rearrangements into unique semicrystalline multilamellar shells, for which curvature (type of emulsion) can be tuned by the molecular architecture (volume fractions of the blocks) and/or by the temperature. The latter trigger affects both the solubility of the PEO block in water and the semicrystalline state of the PCL block. Remarkably, multilamellar semicrystalline shells provide both long-term stability and enhanced barrier properties of toluene-water emulsions, as well as the fast change of the bending, leading to thermo-induced phase inversion. These findings signify the development of novel practical mechanisms for controlled triggered encapsulation and release systems. © 2016 American Chemical Society.

Vol. 18(23), pp. 15667-15672 
article DOI URL 
Abstract: Thanks to density functional calculations, the influence of hydrogenation on the interactions between a (2 × 2) germanene layer and a (3 × 3) Al(111) substrate has been investigated. It appears that the Ge-Al inter-atomic distance increases with hydrogen coverage, while the interaction energy and charge transfer between the Ge layer and the Al topmost plane drastically diminish, thus reducing the electrostatic interactions. Moreover, hydrogenation also lowers the electron density at the interface, weakening the chemical interaction between the Ge layer and the Al surface, and opening the door to a possible decoupling of the germanene layer from the Al substrate. © 2016 the Owner Societies.

Abstract: The thermodynamic of the adsorption of seven organic pollutants, namely benzotriazol, bisphenol A, caffeine, carbamazepine, diclofenac, ofloxacin, and pentachlorophenol, was studied on a microporous-activated carbon fabric. The isosteric adsorption quantities (Gibbs energy, enthalpy, and entropy variations) at high coverage ratio (around 1 mmol/g) have been determined from the adsorption isotherms at three temperatures (13, 25, and 40 °C). The adsorption heats at very low coverage (about 10−5 mmol/g) have been measured by flow micro calorimetry. The experimental adsorption energies were correlated to the adsorbate-adsorbent and the adsorbate-solvent interaction energies calculated by simulations using the COSMO-RS model. The main role of the van der Waals forces in the adsorption of the studied molecules was established. The bulkier the adsorbate is, the lower the adsorption Gibbs energy variation at high coverage deduced from the isotherms. The heterogeneity of the adsorption sites was brought out by calorimetric measurements. At high coverage, a physisorption phenomenon was observed. At very low coverage, high values of the adsorption heats were found (ranging from −58 to −110 kJ/mol), except for pentachlorophenol characterized by an athermal adsorption controlled by Pi-anions interactions. © 2016 Springer-Verlag Berlin Heidelberg

Mechehoud, F., Khelil, A., Hakiki, N. and Bubendorff, J. Potentiostatic controlled nucleation and growth modes of electrodeposited cobalt thin films on n-Si(1 1 1) 2016 Eur. Phys.J.Appl.Phys
Vol. 75, pp. 30301 
article DOI  
Abstract: The nucleation and growth of Co electrodeposits on n-Si(1 1 1) substrate have been investigated
as a function of the applied potential in a large potential range using electrochemical techniques (voltammetry
and chrono-amperometry) and surface imaging by atomic force microscopy (AFM). The surface
preparation of the sample is crucial and we achieve a controlled n-Si(1 1 1) surface with mono-atomic steps
and flat terraces. Using Scharifker-Hills models for fitting the current-time transients, we show that a
transition from an instantaneous nucleation process to a progressive one occurs when the overpotential
increases. A good agreement between the nucleation and growth parameters extracted from the models
and the AFM data’s is observed. The growth is of the Volmer-Weber type with a roughness and a spatial
extension in the substrate plane of the deposited islands that increase with thickness

Abstract: This work is devoted to the development and application of a new experimental method that combines in situ ultrafast calorimetry on a chip with nanofocus synchrotron X-ray diffraction. In the present work, this method is used to study the melting mechanisms of samples of semicrystalline polymers with the mass of a few tens of nanograms. Such studies are relevant when working with materials that are characterized by complex phase behavior, for example, prone to transitions into metastable states or demonstrating fast processes of structural adjustment during thermal treatment. © 2016, Pleiades Publishing, Ltd.

Melnikov, A., Rosenthal, M., Rodygin, A., Doblas, D., Anokhin, D., Burghammer, M. and Ivanov, D.c. Re-exploring the double-melting behavior of semirigid-chain polymers with an in-situ combination of synchrotron nano-focus X-ray scattering and nanocalorimetry 2016 European Polymer Journal
Vol. 81, pp. 598-606 
article DOI URL 
Abstract: A combination of nano-focus X-ray scattering and nanocalorimetry was used to re-explore the phenomenon of multiple melting behavior of a typical semirigid-chain polymer, poly(trimethylene terephthalate), PTT. The multiple melting of semirigid-chain polymers constitutes one of the long-standing issues in polymer physics. By using very high heating and cooling rates the micro-structure of PTT corresponding to different stages of melting has been arrested by quenching it to room temperature. Although the recrystallization of PTT can be largely precluded under these conditions, the nanocalorimetric curve exhibits two melting events. By employing an in-situ small-angle X-ray scattering, SAXS, it is observed that the low-temperature melting peak corresponds to formation of streaky SAXS patterns. At this stage, the crystalline lamellar stacks lose their long-range order due to melting of the crystals confined in the smallest amorphous gaps, which can be explained by the negative stresses imposed on these crystals. This low-melting crystal fraction can be selectively molten away by performing a fast heating just above the corresponding melting point, and the subsequent heating does not reveal the double-melting behavior anymore. Therefore the phenomenon of the double (or multiple) melting behavior is not necessarily coupled to the melting–recrystallization processes and can be observed even in the absence of any recrystallization. © 2016 Elsevier Ltd

Vol. 133(12), pp. 43213 
article DOI  
Abstract: d A novel photoinitiator based on a spiroxanthene scaffold in the presence of an iodonium salt is proposed for the cationic ring-opening polymerization of a diepoxide, as well as for the free-radical polymerization of an acrylate upon violet LED exposure (385 and 405 nm). Good-to-excellent rates of polymerization and final conversions are obtained. These systems are characterized by a higher reactivity compared with that of anthracene/iodonium salt used as reference for cationic near UV polymerization. The addition of a poly(ionic liquid) improves the cationic polymerization profiles. The photochemical mechanisms are studied by steady-state photolysis, fluorescence, and electron spin resonance spin-trapping techniques. Molecular orbital calculations give an insight into the light absorption properties. (C) 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43213.

Abstract: Four perovskites (LaTiO3, LaCrO3, La0.6Sr0.4MnO3 and MAPbI3) are proposed here as new photoinitiators (e.g., free radical generators) in combination with iodonium salt and optionally another additive (N-vinylcarbazole--NVK) to initiate both radical and cationic photopolymerization reactions. The proposed systems are efficient phenyl radical generators under polychromatic light sources such as a halogen lamp or a Xe-Hg lamp. The interest of this approach is the ability to work with very stable inorganic structures as photoinitiators. To the best of our knowledge, this is the first time that perovskites are incorporated in photoinitiating systems. Photochemical mechanisms will be proposed as sustained by electron spin resonance spin trapping (ESR-ST) experiments. © 2016 Elsevier Ltd

Montégut, G., Michelin, L., Brendlé, J., Lebeau, B. and Patarin, J. Ammonium and potassium removal from swine liquid manure using clinoptilolite, chabazite and faujasite zeolites 2016 Journal of Environmental Management
Vol. 167, pp. 147-155 
article DOI URL 
Abstract: This study concerns cationic exchanges performed in order to remove ammonium and potassium cations from manure by using various zeolites: clinoptilolite, chabazite and NaX faujasite. First, the effect of temperature (25 °C and 40 °C) on the exchange rate between zeolites and an ammonium chloride solution was investigated. Then, cationic exchanges were performed on these three zeolites using on one side a mixed ammonium and potassium chloride solution reproducing the chemical composition of a swine manure and on the other side the corresponding liquid manure. No significant difference was observed on the exchange rate and the trapping of ammonium cations by changing the temperature (25 or 40 °C). Clinoptilolite showed a good selectivity towards ammonium cations using model (NH4Cl, and mixed NH4Cl/KCl) solutions but is less efficient with the liquid manure. Chabazite and faujasite were found more efficient than clinoptilolite for trapping ammonium cations. However, NaX faujasite enables trapping 3 times more ammonium cations than chabazite from manure (60 and 20 mg/g, respectively). Moreover, chabazite allowed to trap the same amount of potassium cations than NaX faujasite (33 and 35 mg/g, respectively). © 2015 Elsevier Ltd.

Vol. 61, pp. 736-743 
article DOI URL 
Abstract: Samples of crystalline hydroxyapatite (HA) with and without the addition of individual Mg2 +, Mn2 + and Sr2 + ions and samples with the addition of all three ions simultaneously were prepared using the precipitation method in an aqueous medium. Chemical, structural, spectroscopic and thermophysical analyses of the synthesized samples were conducted. The obtained results indicate that Sr2 + ions were easily incorporated into the HA crystal structure, whereas it was difficult to incorporate Mg2 + and Mn2 + ions into the HA lattice when these ions were individually introduced into the samples. The synthesis of HA with Mg2 + or Mn2 + ions is characterized by the formation of HA with a low concentration of doping elements that is outweighed by the amount of these atoms present in less biocompatible phases that formed simultaneously. However, the incorporation of Sr2 + along with Mg2 + and Mn2 + ions into the samples allowed for the synthesis of HA with considerably higher concentrations of Mg2 + and Mn2 + in the crystal lattice. © 2015 Elsevier B.V.

Abstract: In the present paper, new photoinitiators based on the meta-terphenyl scaffold in combination with an iodonium salt and 9H-carbazole-9-ethanol (CARET) are proposed for the free radical promoted cationic polymerization of epoxides upon visible light exposure using light emitting diodes at 405, 455, and 470 nm. Remarkably, a new high performance additive (i.e., CARET) is proposed here for cationic polymerizations. CARET shows some important advantages compared to other reported additives such as N-vinylcarbazole or benzyl alcohol used as references. Excellent polymerization initiating abilities are found and a full picture of the involved chemical mechanisms is provided. (Figure presented.). © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Vol. 304, pp. 532-542 
article DOI URL 
Abstract: 3-Aminopropyltrimethoxysilane (APTMS) was used as ligand to prepare ZnO at APTMS, Cu2+-doped ZnO (ZnO:Cu at APTMS) and ZnO quantum dots (QDs) with chemisorbed Cu2+ ions at their surface (ZnO at APTMS/Cu). The dots have a diameter of ca. 5nm and their crystalline and phase purities and composition were established by X-ray diffraction, transmission electron microscopy, UV-visible and fluorescence spectroscopies and by X-ray photoelectron spectroscopy. The effect of Cu2+ location on the ability of the QDs to generate reactive oxygen species (ROS) under light irradiation was investigated. Results obtained demonstrate that all dots are able to produce ROS (OH, O2 -, H2O2 and 1O2) and that ZnO at APTMS/Cu QDs generate more OH and O2 - radicals and H2O2 than ZnO at APTMS and ZnO:Cu at APTMS QDs probably via mechanisms associating photo-induced charge carriers and Fenton reactions. In cytotoxicity experiments conducted in the dark or under light exposure, ZnO at APTMS/Cu QDs appeared slightly more deleterious to Escherichia coli cells than the two other QDs, therefore pointing out the importance of the presence of Cu2+ ions at the periphery of the nanocrystals. On the other hand, with the lack of photo-induced toxicity, it can be inferred that ROS production cannot explain the cytotoxicity associated to the QDs. Our study demonstrates that both the production of ROS from ZnO QDs and their toxicity may be enhanced by chemisorbed Cu2+ ions, which could be useful for medical or photocatalytic applications. © 2015 Elsevier B.V..

Vol. 105, pp. 628-637 
article URL 
Abstract: Abstract The effect of surface functionalities on the supercapacitors performances has been highlighted often in many works. However, studies devoted to the influence of carbon defects did not gain particular attention due to the difficulty to quantify such parameter. In this context, carbon nano-onions were used as model material in order to understand the influence of the surface chemistry (nature and amount of oxygen groups) and structural defects (active surface area, ASA) on the capacitance. Different types of thermal treatments in oxidizing or reducing atmospheres allowed to finely tune the surface chemistry and the ASA as demonstrated by temperature programmed desorption coupled with mass spectrometry (TPD-MS). For the first time, the presice control of these characteristics independently one of each other allowed to highlight an important influence of the carbon defects on the capacitance in organic and aqueous electrolytes which outbalance the oxygen functional group effect.

Vol. 94(7), pp. - 
article DOI URL 
Abstract: In previous studies, we have shown that gold deposited on a monolayer (ML) of graphene on SiC(0001) is intercalated below the ML after an annealing procedure and affects the band structure of graphene. Here we prove experimentally and theoretically that some of the gold forms a dispersed phase composed of single adatoms, being intercalated between the ML and the buffer layer and in a hollow position with respect to C atoms of the ML on top. They are freestanding and negatively charged, due to the partial screening of the electron transfer between SiC and the ML, without changing the intrinsic n-type doping of the ML. As these single atoms decouple the ML from the buffer layer, the quasiparticles of graphene are less perturbed, thus increasing their Fermi velocity. Moreover, the hollow position of the intercalated single Au atoms might lead to spin-orbit coupling in the graphene layer covering IC domains. This effect of spin-orbit coupling has been recently observed experimentally in Au-intercalated graphene on SiC(0001) [D. Marchenko, A. Varykhalov, J. Sánchez-Barriga, Th. Seyller, and O. Rader, Appl. Phys. Lett. 108, 172405 (2016)APPLAB0003-695110.1063/1.4947286] and has been theoretically predicted for heavy atoms, like thallium, in a hollow position on graphene [C. Weeks, J. Hu, J.

Vol. 109, pp. 227-238 
article URL 
Abstract: Abstract A combined salt-soft template approach to synthesize porous carbon materials is reported along with their synthesis mechanism. This consists in the evaporation induced self-assembly (EISA) of aqueous solutions containing green phenolic resins, a triblock copolymer template and a metallic salt, followed by thermal treatment and washing. The increase of pH up to 5 using NaOH, induces significant improvement in the carbon microporosity but in the detrimental of mesoporosity. As suggest by 13C and 1H NMR, the mesoporosity lost is caused by the decrease of H-bonding and self-assembly between the phenolic resin and the template due to the strong “salting-out” effect of OH ions. For higher pH (pH-9), the porosity start to decrease and graphene-sheet like morphology is formed. The microporosity varies with the salt in the following order: KCl &gt; NaCl &gt; LiCl, while the mesoporosity in the opposite way. The structure changes as well from smooth turbostatic (KCl) to defective graphitic one (NaCl, LiCl). These textural and structural modifications are explained in terms of cation hydration enthalpy and cation-π binding energy and by the competition between the metal salt cations and the Na ions (used to regulate the pH) for water or phenolic resin aromatic ring sites.

Abstract: A novel and efficient method for the generation of phosphinoyl radicals from the combination of diphenyliodonium salt (Ph2I+,-OTf) with triethylamine (Et3N) in the presence of secondary phosphine oxides is reported. By employing this practical and simple approach, a large variety of 6-phosphorylated phenanthridines have been synthesized through the addition of phosphinoyl radicals to isonitriles as radical acceptors. The reaction works smoothly in the absence of any transition metal or photocatalyst. On the basis of electron paramagnetic resonance (EPR) and density functional theory (DFT) calculations, the mechanism of this reaction is discussed.

Oumellal, Y., Provost, K., Ghimbeu, C., De Yuso, A. and Zlotea, C. Composition and size dependence of hydrogen interaction with carbon supported bulk-immiscible Pd-Rh nanoalloys 2016 Nanotechnology
Vol. 27(46), pp. -

Abstract: In-depth clarification of hydrogen interaction with noble metal nanoparticles and nanoalloys is essential for further development and design of efficient catalysts and hydrogen storage nanomaterials. This issue becomes even more challenging for nanoalloys of bulk-immiscible metals. The hydrogen interaction with bulk-immiscible Pd-Rh nanoalloys (3-6 nm) supported on mesoporous carbon is studied by both laboratory and large scale facility techniques. X-ray diffraction (XRD) reveals a single phase fcc structure for all nanoparticles confirming the formation of nanoalloys in the whole composition range. In situ extended x-ray absorption fine structure (EXAFS) experiments suggest segregated local structures into Pd-rich surface and Rh-rich core coexisting within the nanoparticles. Hydrogen sorption can be tuned by chemical composition: Pd-rich nanoparticles form a hydride phase, whereas Rh-rich phases do not absorb hydrogen under ambient temperature and pressure conditions. The thermodynamics of hydride formation can be tailored by the composition without affecting hydrogen capacity at full hydrogenation. Furthermore, for hydrogen absorbing nanoalloys, in situ EXAFS reveals a preferential occupation of hydrogen for the interstitial sites around Pd atoms. To our knowledge, this is the first study providing insights into the hydrogen interaction mechanism with Pd-Rh nanoalloys that can guide the design of catalysts for hydrogenation reactions and the development of nanomaterials for hydrogen storage. © 2016 IOP Publishing Ltd.

Vol. 219, pp. 306-310 
article DOI URL 
Abstract: Pure silica ITQ-7 zeolite of topology ISV synthesized in fluoride media possesses a 3D 12-membered-rings pore system. Originally the structure of ITQ-7 zeolite was solved and refined from a calcined sample in the highest possible space group symmetry P42/mmc. This space group leads to only 5 independent silicon T sites for this structure. However, this high symmetry was not supported by solid state 29Si MAS NMR spectroscopy. In this short communication, we show from a revised 29Si solid state MAS NMR and Rietveld analyses, that lowering of the space group symmetry from P42/mmc to P42 consolidates structure model and experimental data, in particular, the number of non equivalent crystallographic T sites passing from 5 to 16, is in agreement with 29Si solid state NMR spectroscopy. © 2015 Elsevier Inc.

Vol. 40(5), pp. 4228-4235 
article DOI URL 
Abstract: Powder neutron diffraction is used to follow structural changes occurring during heat and vacuum assisted dehydration of 3 wt% nickel exchanged NaY. The structures determined from Rietveld refinement confirm the nickel ion displacement from the supercages and sodalite cages towards hexagonal prisms upon water removal. Not only this mobility but also its relationship with the dehydration level is demonstrated, owing to real time quantification of dehydration through changes in the intensity of the incoherent neutron scattering signal. Comparison with TGA data proves that this signal is fully attributable to water molecules adsorbed in the zeolite. STEM/EDX and in situ heating TEM studies provide complementary information on homogeneous Ni distribution (initial state) and on reductive sintering in vacuum at a high temperature. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2016.

Vol. 138(23), pp. 7436-7441 
article DOI URL 
Abstract: Highly functionalized benzo[b]phosphole oxides were synthesized from reactions of arylphosphine oxides with alkynes under photocatalytic conditions by using eosin Y as the catalyst and N-ethoxy-2-methylpyridinium tetrafluoroborate as the oxidant. The reaction works under mild conditions and has a broad substrate scope. Mechanistic investigations have been undertaken and revealed the formation of a ground state electron donor-Acceptor complex (EDA) between eosin (the photocatalyst) and the pyridinium salt (the oxidation agent). This complex, which has been fully characterized both in the solid state and in solution, turned out to exhibit a dual role, i.e., the oxidation of the photocatalyst and the formation of the initiating radicals, which undergoes an intramolecular reaction avoiding the classical diffusion between the two reactants. The involvement of ethoxy and phosphinoyl radicals in the photoreaction has unequivocally been evidenced by EPR spectroscopy. © 2016 American Chemical Society.

Vol. 69, pp. 311-320 
article DOI URL 
Abstract: To study the biological activity effects of femtosecond laser-induced structures on cell behavior, TA6V samples were micro-textured with focused femtosecond laser pulses generating grooves of various dimensions on the micrometer scale (width: 25–75 μm; depth: 1–10 μm). LIPSS (Laser Induced Periodic Surface Structures) were also generated during the laser irradiation, providing a supplementary structure (sinusoidal form) of hundreds of nanometers at the bottom of the grooves oriented perpendicular (⊥ LIPPS) or parallel (// LIPPS) to the direction of these grooves. C3H10 T1/2 murine mesenchymal stem cells were cultivated on the textured biomaterials. To have a preliminary idea of the spreading of biological media on the substrate, prior to cell culture, contact angle measurement were performed. This showed that the post-irradiation hydrophilicity of the samples can decrease with time according to its storage environment. The multiscale structuration either induced a collaborative or a competitive influence of the LIPSS and grooves on the cells. It has been shown that cells individually and collectively were most sensitive to microscale grooves which were narrower than 25 μm and deeper than 5 μm with ⊥ LIPPS. In some cases, cells were individually sensitive to the LIPSS but the cell layer organization did not exhibit significant differences in comparison to a non-textured surface. These results showed that cells are more sensitive to the nanoscale structures (LIPSS), unless the microstructures's size is close to the cell size and deeper than 5 μm. There, the cells are sensitive to the microscale structures and go on spreading following these structures. © 2016 Elsevier B.V.

Revol, B.b., Thomassey, M., Ruch, F. and Nardin, M. Influence of the sample number for the prediction of the tensile strength of high tenacity viscose fibres using a two parameters Weibull distribution 2016 Cellulose
Vol. 23(4), pp. 2701-2713 
article DOI URL 
Abstract: The objective of this work is to determine an adequate number of samples for an accurate prediction of tensile strength of fibres using a Weibull distribution. Theory will be compared to experimental results in order to know the effect of experimental errors on the theoretical expectations. The diameter and strength distribution of high tenacity viscose were evaluated. The chosen Weibull distribution was with two parameters. First, the best probability estimator for Weibull was determined using a random selection of experimental datas. Then, in order to be able to predict the number of sample knowing the variation of the Weibull modulus m, different relationship between the coefficient of variation of m and the number of sample n were tested. The relationship CV = 0.78/n presented good agreement with experimental datas. The influence of the variation of m on the predicted value of strength was studied in order to determine an adequate number of sample to obtain limited variation of the predicted strength. The last part focus on experimental verification of the points previously developed. It was shown that it is possible to determine the influence of the variation of the Weibull modulus on the predicted strength. However, no correlation was found between the variations of the Weibull modulus and the error on the predicted strength. © 2016, Springer Science+Business Media Dordrecht.

Vol. 221, pp. 228-237 
article DOI URL 
Abstract: Due to their properties nano-emulsions are excellent candidates to be used as imprints to create a macropore network. In this study nano-emulsions have been formulated from the Remcopal 4/decane/water system and mineralized by a dual templating mechanism in the presence of Pluronic P123 micelles. After removing the organic matter, macro-mesostructured silica materials are obtained. Small angle X-ray scattering patterns of the materials and transmission electronic microscopy experiments show that the mesoporous network (mesopore size around 9 nm) adopts a hexagonal arrangement. Macropores have been characterized by transmission electron microscopy, scanning electron microscopy and mercury porosity. As determined by mercury porosimetry, the size of the macropores imprinted by the nano-emulsions is of about 240 nm. A second macroporosity is also detected in the micrometer range and could be related to the further fusion of nano-emulsions during the hydrothermal process and to interparticular porosity. To better address the formation mechanism of the hierarchical structure of the silica material, the stability of nano-emulsions in the presence of methanol, P123 and both of them has been investigated. We have also evidenced the dual role played by the Pluronic micelles. They do not only induce the mesopore network through the cooperative templating mechanism, but their presence also avoids the total destructuration of the nano-emulsion by methanol, released during the hydrolysis of the silica precursor. © 2015 Elsevier Inc.

Trojan-Like Internalization of Anatase Titanium Dioxide Nanoparticles by Human Osteoblast Cells 2016 Scientific Reports
Vol. 6, pp. 23615 
article DOI  
Abstract: Dentistry and orthopedics are undergoing a revolution in order to provide more reliable, comfortable and long-lasting implants to patients. Titanium (Ti) and titanium alloys have been used in dental implants and total hip arthroplasty due to their excellent biocompatibility. However, Ti-based implants in human body suffer surface degradation (corrosion and wear) resulting in the release of metallic ions and solid wear debris (mainly titanium dioxide) leading to peri-implant inflammatory reactions. Unfortunately, our current understanding of the biological interactions with titanium dioxide nanoparticles is still very limited. Taking this into consideration, this study focuses on the internalization of titanium dioxide nanoparticles on primary bone cells, exploring the events occurring at the nano-bio interface. For the first time, we report the selective binding of calcium (Ca), phosphorous (P) and proteins from cell culture medium to anatase nanoparticles that are extremely important for nanoparticle internalization and bone cells survival. In the intricate biological environment, anatase nanoparticles form bio-complexes (mixture of proteins and ions) which act as a kind of 'Trojan-horse' internalization by cells. Furthermore, anatase nanoparticles-induced modifications on cell behavior (viability and internalization) could be understand in detail. The results presented in this report can inspire new strategies for the use of titanium dioxide nanoparticles in several regeneration therapies.

Vol. 221, pp. 167-174 
article DOI  
Abstract: MFI-type zeolite pellets were elaborated with a hydraulic press in the presence of a small amount of binder (methylcellulose (MC) or anhydrous sodium metasilicate (Na2SiO3)) for molecular decontamination, in particular for the space field. The influence of the compression load and the amount of binder was investigated to determine the optimum conditions to get pellets with high mechanical performances and high adsorption capacities. The compression load varied from 2 to 8 tons and the amount of binder varied from 5 to 20 wt% of the total pellet weight. Nitrogen sorption-desorption revealed a small loss of micropore volume (17%) with a compression load of 8 tons (0.15 cm(3)/g instead of 0.18 cm(3)/g for the MFItype zeolite powder), which can be attributed to a partial amorphization. Adsorption kinetics of n-hexane showed that the optimum pellets can adsorb volatile organic compounds. Indeed, MFI-type zeolite adsorbs 7.6 molecules of n-hexane per cell whereas the pellets made with 5 wt% of MC or Na2SiO3 adsorb about 7 molecules of n-hexane per unit-cell, respectively. These results are coherent with the ones obtained with nitrogen sorption-desorption. Uniaxial compression tests showed that the addition of small amount of binder in the mixture really improved the mechanical performances: the ultimate compressive strength was multiplied by 8 (10 MPa for the pellets without binder) when only 5 wt% of MC are used (80 MPa), with a compression load of 4 tons.

Vol. 6(3), pp. 2470-2478 
article DOI URL 
Abstract: FAU-type zeolite beads were formed through an shearer/mixer using organic binder (carboxymethylcellulose (CMC)) or inorganic binder (anhydrous sodium metasilicate (Na2SiO3)). Mechanical and adsorption properties of these beads represent necessary characteristics for applications in molecular decontamination. The amount of binder and the size of beads were investigated to determine the optimum conditions to elaborate mechanically stable beads with high adsorption capacities. The size of beads varies from 0.25 mm to 2 mm and the amount of binder was tuned from 5 to 15 wt% of the total bead weight. Nitrogen adsorption-desorption measurements reveal no loss of micropore volume when 5 wt% of binder is used. Adsorption of pollutants were successfully carried out using n-hexane and 1,2-dichlorobenzene as probe molecules. Indeed, FAU-type zeolite adsorbs 26 molecules of n-hexane and 29 molecules of 1,2-dichlorobenzene per unit-cell, whereas the beads prepared with 5 wt% of CMC or Na2SiO3 adsorb about 24 molecules of n-hexane and 25 molecules of 1,2-dichlorobenzene per unit-cell, respectively. The mechanical performances are improved with the addition of only 5 wt% of binder in the mixture. Uniaxial compression tests show that the ultimate compressive strength was multiplied by 4 or 7 when only 5 wt% of CMC or sodium silicate are respectively involved for the conception of 1-2 mm zeolite beads. © the Owner Societies 2016.

Abstract: The energetic performances of several FAU- and∗BEA-type zeolites with different Si/Al molar ratios have been studied by high pressure intrusion-extrusion of water and LiCl aqueous solutions. It has been shown that FAU-type zeolites characterized by a low Si/Al molar ratio (up to 40) demonstrate hydrophilic properties and spontaneous intrusion of water and LiCl solutions. While dealuminated Y zeolite (DaY) with a Si/Al ratio of 110 displayed a shock-absorber behavior under intrusion of LiCl solutions with concentration ranging from 5 to 20 M; however the intrusion of water was spontaneous. The increase of the LiCl concentration leads to an increase of both the intrusion pressure and the intruded volume, but also a better efficiency of the shock-absorber.∗BEA-type zeolite with a Si/Al ratio of 90 displayed a spring behavior under intrusion of 20 M LiCl solution with an intrusion pressure of 59 MPa and an intruded volume of 0.09 mL/g, whereas the intrusion of solutions with lower concentration was spontaneous. It has been shown that only zeolites with high Si/Al ratios can demonstrate high pressure intrusion of electrolyte solutions and that the presence of small traces of aluminum atoms changes considerably the behavior of the "zeolite-liquid" system. The characterization of the samples, before and after intrusion-extrusion experiments, by various physicochemical and structural methods has been performed. © 2015 Published by Elsevier Inc.

Abstract: Bilayer zeolite films ZSM-5/ZSM-5, ZSM-5/EMC-1 and NaY/ZSM-5 were synthesized on α-alumina plates. The bottom ZSM-5 or faujasite Y (NaY) zeolite layers were obtained by direct hydrothermal synthesis or by using a seeding step followed by a secondary growth method, respectively, while the secondary growth method was used for the synthesis of all the top zeolite layers. A complete characterization of the obtained materials is proposed using various techniques, such as X-ray diffraction, scanning electron microscopy, X-ray fluorescence and nitrogen sorption measurements. Continuous and highly crystallized bi-layer zeolite films with thicknesses around 11-18 μm were obtained. © 2015 Académie des sciences. Published by Elsevier Masson SAS.

Abstract: An adhesive based on the reaction of a very fast reacting procyanidin-type condensed tannin, namely purified pine bark tannin, and food-grade non-toxic slow-reacting aldehydes derived from lignin was shown to satisfy well the relevant standards for bonding wood particleboard. Vanillin and a dialdehyde derivative of vanillin were the aldehydes used. The oligomers obtained and their distribution have been determined by matrix assisted laser ionization desorption time-of-flight (MALDI-TOF) mass spectrometry for the reactions with catechin used as a model compound and with the pine tannin itself, and by cross polarization magic angle spinning 13C nuclear magnetic resonance (CP MAS 13C NMR) for the reaction with pine tannin. © 2016 Elsevier Ltd

Vol. 47(2), pp. 1263-1273 
article  
Abstract: This paper deals with the development of a novel and predictive finite element method (FEM) model coupling electrical, thermal, and mechanical time-dependent contributions for simulating the behavior of a powdery material submitted to a spark plasma sintering (SPS) treatment by using COMSOL Multiphysics® software. The original approach of this work lies in the use of the modified Cam-Clay model to solve the mechanical phenomenon occurring during a SPS sintering treatment. As the powder properties and behaviors are different from the final sintered material and display a nonlinear dependence as a function of temperature and pressure, the model includes the description of the sample densification. In this way, numerical and experimental results obtained on conductive model material (aluminum) such as temperature, stress distributions, and shrinkage, were directly compared. This FEM model demonstrated the ability to predict the powder behavior during temperature-controlled experiments precisely, as they are typically performed in the SPS technique. This approach exhibits a remarkable level of interest because it takes into account the nature of the material and also the specific characteristics of the powder studied.

article DOI URL 
Abstract: Aerosol flame technology has been used for decades to fabricate on an industrial scale a range of inorganic (nano)particles, including carbon blacks, titania, and fumed silica. Nevertheless, the high local temperatures inherent to this technique prevent direct organic functionalization or loading by organic derivatives, which is essential in many applications to achieve specific properties and optimal dispersion within an organic matrix. We describe herein a novel eco-friendly UV process allowing single-step manufacture of high-value silica and organosilica particles at ambient temperature. Atomized alkoxysilane precursor droplets are produced within an annular photoreactor including 6 fluorescent UV lamps (maximum emission: 312 nm), and photocondensed continuously after a 1 min single pass. Droplet condensation is controlled by the release of a photoacid catalyst localized in the droplets, affording spherical polydisperse powder particles with a mean diameter ranging around 400-700 nm. In the presence of an amphiphilic block copolymer template, a silica/surfactant mesostructured film was deposited using this UV aerosol technology, resulting in a wormlike mesoporous structure after calcination.

Abstract: In the framework of density functional theory, the adsorption of the halogenated polycyclic aromatic hydrocarbon 2,11-diiodohexabenzocoronene (HBC-I2) on the SiC(0001) 3×3 surface has been investigated. Nondissociative and dissociative molecular adsorption is considered, and simulated scanning tunneling microscopy (STM) images are compared with the corresponding experimental observations. Calculations show that dissociative adsorption is favorable and reveal the crucial importance of the extended flat carbon core on molecule-surface interactions in dissociative adsorption; the iodine atom-surface interaction is of minor importance. Indeed, removing iodine atoms does not significantly affect the STM images of the central part of the molecule. This study shows that the dissociation of large halogenated polycyclic aromatic hydrocarbon molecules can occur on the SiC surface. This opens up interesting perspectives in the chemical reactivity and functionalization of wide band gap semiconductors. © 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

Abstract: The electronic structure of germanene is investigated by high resolution photoemission and density functional theory calculations. The core level Al 2p and Ge 3d lines are measured on germanene grown on Al(111) by using synchrotron radiation. The Ge 3d line is shifted toward the low binding energies with respect to bulk Ge, and shows three components, reflecting the sites multiplicity of the germanene atomic structure. The calculations reveal a sizable charge localization at the germanene/Al(111) interface, a charge transfer from the Al surface atoms to the germanene, and the existence of three nonequivalent Ge sites with three different atomic Bader charges, in agreement with the photoemission measurements. © 2015 American Chemical Society.

Vol. 643, pp. 65-72 
article DOI URL 
Abstract: The polymerization kinetics of p-xylylene in condensed state was studied by in situ non-isothermal DSC measurements, using a custom-made heat-flux calorimeter integrated into a vacuum vapor deposition polymerization reactor. The temperature range (−110 to −75 °C) and the total heat effect (Q = 86 ± 8 kJ mol−1) of the polymerization reaction were found to be almost identical to the values previously measured ex situ with a commercial Perkin Elmer DSC7 calorimeter. The differential isoconversional method by Friedman was applied for the kinetics analysis. The effective activation energy exhibits variation with the degree of conversion in the range from 30 kJ mol−1 to 50 kJ mol−1 indicating the complexity of the reaction mechanism. To evaluate the reaction model f(α) a model-free method based on the use of the compensation effect has been employed. The calculated f(α) values are adequately fitted to the Avrami–Erofeev A2 model in the conversion degrees interval of 20–80%. The discrepancy observed at the end of the reaction is probably due to diffusion control of the reaction, whereas the complexity of the reaction mechanism can be a reason of the discrepancy at low degrees of conversion. © 2016 Elsevier B.V.

Vol. 54(5), pp. 702-713 
article DOI URL 
Abstract: This article reports on the presumably first use of iron complexes (FeC) as potential photocatalysts for controlled radical photopolymerization reactions (CRP2). Three compounds were designed and investigated. Good linear evolutions of the molecular weight (Mn) with the conversion were observed. A comparison was provided with a reference iridium (III) complex [Ir(ppy)3 where ppy stands for 2-phenylpyridine]. The on/off photopolymerization experiments highlight the presence of dormant species and a re-initiation on demand upon irradiation. This unique re-initiation property was used for the modification of surfaces (hydrophilic/hydrophobic properties) and surface patterning as well as the synthesis of a block co-polymer (PMMA-b-PBA). A comparative analysis of the behavior of these iron complexes in thermally and photochemically activated polymerization was provided. The chemical mechanisms were studied by steady state photolysis, laser flash photolysis, cyclic voltammetry, luminescence quenching, and electron spin resonance experiments. A catalytic cycle was proposed with two steps: (i) the oxidation of the FeC excited state by an alkyl halide and (ii) the reduction by the oxidized form (FeC°+) by an amine or the macroradicals leading to the regeneration of the catalyst. © 2015 Wiley Periodicals, Inc.

Vol. 19(1-2), pp. 71-78 
article DOI  
Abstract: The photoredox catalysis applied to the field of polymers and more particularly to the
design of photoinitiating systems is briefly reviewed. Two novel phenylisoquinoline-based
iridium complexes with fluorine substituents (bis[5-fluoro-2-(1-isoquinolinyl-kN)phenylkC](
2,2,6,6-tetramethyl-3,5-heptanedionato-kO3,kO5)-iridium (III) (Ir_b) and bis[3,5-difluoro-
2-(1-isoquinolinyl-kN)phenyl-kC](2,2,6,6-tetramethyl-3,5-heptanedionato-kO3,kO5)-iridium
(III) (Ir_c) are proposed as photoredox catalysts (also called photoinitiator catalysts) and
incorporated into suitable photoinitiating systems for cationic and radical polymerization.
(3,4-Epoxycyclohexane)methyl-3,4-epoxycyclohexylcarboxylate (EPOX) and trimethylolpropane
triacrylate (TMPTA) were used as benchmark monomers for cationic and radical
photopolymerization. These new catalysts are compared to our very recently proposed
unsubstituted catalyst compound: bis[2-(1-isoquinolinyl-kN)phenyl-kC](2,2,6,6-tetramethyl-
3,5-heptanedionato-kO3,kO5)-iridium (III) (Ir_a). Remarkably, these catalysts exhibit
improved light absorption properties and are characterized by a panchromatic behavior
which ensures the photosensitivity of the polymerizable films to blue, green and red lights.
The photochemical properties as well as the chemical mechanisms associated with these
catalysts are investigated by ESR spin-trapping, laser flash photolysis, steady state photolysis,
cyclic voltammetry and luminescence experiments. The structure/reactivity relationships as
well as the substitution effect (by the fluorine) are discussed.

Abstract: Stereoselective hydrometalation reactions of aryl- and alkyl-substituted trifluoromethylated alkynes with triethylsilane, tributylstannane, and triphenylgermane were investigated. (E)-α-CF3-Vinylsilanes I, -stannanes e.g., II, and -germanes e.g., III, were obtained under palladium-catalyzed conditions whereas the corresponding (Z)-α-CF3-vinylgermanes were obtained under radical conditions. These reactions proceeded in good to excellent yields and possess a broad functional group tolerance. Applications of the (Z)- and (E)-α-CF3-vinylgermanes in palladium-catalyzed cross-coupling reactions with aryl halides having diverse electronic requirements were also investigated. The corresponding (Z)- and (E)-α-CF3-styrenes were obtained as single isomers, thus demonstrating the utility of these versatile synthons for the synthesis of stereodefined trifluoromethylated alkenes.

Vol. 222, pp. 145-152 
article DOI URL 
Abstract: Water adsorption in the large pore (lp-empty) form of Ga-MIL-53 was studied by TGA, DSC and in situ XRD and FTIR at 298 K. The large pore form can be stabilized at room temperature after activation under vacuum at 553 K. The isotherm of water adsorption in this large pore form (pore dimensions: 1.67 × 1.33 nm) is very similar to that measured on the narrow pore (np-empty) form (pore dimensions: 1.97 × 0.76 nm). Such a similarity is rather unusual given that the pore sizes of these two phases are very different. In order to understand the origin of this effect in situ XRD and FTIR measurements were particularly helpful. It was found that the adsorption of even small amount of water (0.05 mol per Ga atom at 0.2 hPa) in the large pore form of Ga-MIL-53 transforms ca. 50% of the solid into a narrow pore int phase, which is assumed to be present as a shell around the lp-empty core. Additional water molecules adsorbed at higher pressures do not interact with the parent lp-empty phase but with the narrow pore int phase. The phase transformations were confirmed by FTIR revealing significant band displacements in the corresponding pressure ranges. Such easy pore shrinking which occurs at very low water pressure (<0.2 hPa) can have undesirable consequences in working conditions, as for example in separation adsorption processes, because the large pore structure of Ga-MIL-53 can be preserved only under anhydrous conditions. © 2015 Elsevier Inc.

Wolak, S., Vidal, L., Becht, J.-M., Michelin, L. and Balan, L. An efficient photochemical route to Pd nanoparticles; application to the one-step synthesis of Pd@polymer nanocomposite films. 2016 Nanotechnology
Vol. 27, pp. 345601 
article  
Abstract: We have developed a facile, efficient, low cost and 'green' photochemical approach to preparing surfactant-free Pd nanoparticles and Pd-immobilized@acrylate photo-polymer films at room temperature, under air and without any additional treatment. The reaction system only includes a photo-initiator used as a generator of free radicals and a Pd(II) salt. In ethanol solution, the photochemical reduction of Pd(II) to Pd(0) generates very small metal particles with a narrow size distribution (2-4 nm). Furthermore, we have shown that the formation of Pd nanoparticles from a Pd(II) salt can be reversible thus allowing easy handling and safe storage with the possibility of generating the nanoparticles just before use. In the presence of an acrylate bifunctional monomer, Pd@polymer film was obtained through a 'one-pot, one-step' process resulting from a simultaneous photo-reduction of Pd(II) and photo-polymerization of acrylate units. The simultaneous generation of a 3D polymer network and of metal particles leads to a homogeneous distribution of Pd nanoparticles in the photo-polymer matrix with an average diameter of approximately 3.7 +/- 1.1 nm. Such as-prepared Pd@polymer films were found to efficiently catalyze the Mizoroki-Heck reaction in the presence of only 0.9 mequiv. of supported palladium. The major interest of this arrangement is its recoverability and reusability, which makes it very attractive both from a practical and economical viewpoint. Finally, it is worth noting that this innovation offers a great advantage over concurrent methods in that it is simply generated within minutes, it is highly stable, and there is sharp monodispersity in the size of the Pd nanoparticles that can be stored for months without alteration of their physico-chemical properties and catalytic activity.

Vol. 35(1), pp. 14-19 
article  
Abstract: Interaction between a model soot (carbon black) and a model NOx storage reduction catalyst (Pt-Ba/Al2O3) is investigated as a function of the strength of the carbon-catalyst contact and the presence or not of H2O in the reactive gas flow. Experiments performed at laboratory scale, using a fixed bed reactor, revealed that the inhibiting effect of carbon on the NOx storage capacity (NSC) of the catalyst increases with the strength of carbon-catalyst contact and affects NOx adsorption on both Al sites and Ba sites, whereas the oxidative function of the catalyst (Pt sites) is not affected. In the presence of water in the reactive gas flow, it was observed that carbon prevents the inhibition of the oxidative function of the catalyst by H2O. On the other hand, the inhibiting effect of carbon on NSC decreases. Hence, a noncumulative effect of carbon and H2O impacts on NSC is observed.

Vol. 132, pp. 128-135 
article URL 
Abstract: Abstract Two D-π-A-type aryl dialkylsulfonium salts with substituted-fluorene as a conjugated system were developed as one-component, versatile photoinitiators under soft irradiation conditions (365-450 nm Light-emitting diodes). The mechanisms for photochemical generation of reactive species (cations and radicals) by the photoinitiators were studied by UV-Vis spectroscopy, theoretical calculations, fluorescence spectroscopy and cyclic voltammetry techniques. The high quantum yields for acid generation (ΦH+ = ∼0.43 to 0.63) of the compounds enable the cationic polymerizations of epoxides and vinyl ether to proceed effectively. Meanwhile, the photocleavage products of sulfoniums (i.e., radicals) initiate the free radical polymerization of acrylate. Such versatile properties allowed them to serve as effective photoinitiators for the synthesis of interpenetrated polymer networks and thiol-ene polymerization without any co-initiators or additives. Based on their beneficial features, these photoinitiators hold great promise for use in photocuring applications.

Vol. 133, pp. 363-371 
article DOI  
Abstract: This paper describes the synthesis and photochemical behavior of two two-branched sulfonium-based photoacid generators (PAGs). The branched structure influences the optical properties of the PAGs by increasing absorption wavelengths and molar extinction coefficients as well as enhancing acid production under one/two-photon irradiation. The two-branched structures collectively showed twofold higher H+ production abilities and improved two-photon absorption cross-sections compared with those in the corresponding mono-branched PAGs. Photochemical mechanisms were investigated through UV-Vis spectra analysis, molecular orbital calculations, and fluorescence analysis. These novel two-branched D-pi-A type sulfonium-based photoinitiating systems are efficient cationic photoinitiators (epoxide conversion = 70%-85% and vinyl conversion > 75%) even under conditions with low initiator concentration (1 wt%) and curing light intensities (5 mW cm(-2)) upon exposure to visible light-emitting diodes (e.g., 405 nm). These two-photon fabricated microstructures also exhibit potential as cationic two photon initiators. (C) 2016 Elsevier Ltd. All rights reserved.

article DOI URL 
Abstract: A series of D-π-A type sulfonium salt photoacid generators with different π-conjugated structures, such as triphenyl, phenylstilbene, styryl-biphenyl, and stilbene, were designed to determine the effect of molecular structures on the photochemical and photophysical properties. The mechanisms of photochemical generation of H+ were studied by UV-Vis spectroscopy, theoretical calculations, and fluorescence spectroscopy. It is found that the frontier orbits determine the absorption, the molar extinction coefficients, and the quantum yields of photoacid generation. Triphenyl systems connected with sulfonium are beneficial to increase the quantum yields of acid generation. The photoreactivity of four sulfonium salts was further evaluated through the polymerizations of various epoxide monomers at different irradiation wavelengths (365–425 nm) by using the real-time infrared spectroscopy with light-emitting diodes. The high quantum yields for acid generation (ΦH + =  0.32 to 0.58) and the high molar extinction coefficients (ε =  23500 L∙mol−1∙cm−1 to 31000 L∙mol−1∙cm−1) of the sulfonium salts lead to high conversion rates (over 50%–80%). Hence, these photoinitiators exhibit potential for the photocuring applications. © 2016, Chinese Chemical Society, Institute of Chemistry, Chinese Academy of Sciences and Springer-Verlag Berlin Heidelberg.

How Molecules with Dipole Moments Enhance the Selectivity of Electrodes in Organic Solar Cells A Combined Experimental and Theoretical Approach 2016 Advanced Energy Materials
Vol. -(*), pp. -- 
article DOI URL 
Abstract: Simple organic molecules with permanent dipole moments – amino acids and heterocycles – have been successfully employed in bulk-heterojunction organic solar cells as interlayer between photoactive material and electron contact. A large increase of open-circuit voltage and fill factor can be observed for four different polymers as donor material in the photoactive layer. A combination of current–voltage curves, scanning Kelvin-probe atomic force microscopy, ultraviolet photoelectron spectroscopy, and electroluminescence measurements as well as numerical simulations are carried out to clarify in detail the underlying mechanisms. All results fully confirm the hypothesis that the main effect is an accumulation of electrons and a depletion of holes in the photoactive layer in the vicinity of the electron contact induced by a decrease of its effective work function. Further, density functional theory calculations and literature reports of the energy levels of the dipole molecules strongly suggest that the charge carriers tunnel through the thin dipole layer which does however not limit the current. This represents a versatile, simple, and cheap method to realize highly selective contacts which may also be beneficial for other types of solar cells and devices where contact selectivity is crucial.

Vol. 6(54), pp. 48684-48693 
article DOI URL 
Abstract: Aminothiazonaphthalimide derivatives (ATNDs) can act as photoinitiators (when combined with iodonium salt, amine, 2,4,6-tris(trichloromethyl)-1,3,5-triazine or N-vinylcarbazole) to start the ring-opening cationic polymerization of epoxides or the radical polymerization of acrylates upon exposure to visible LEDs (405 nm or 455 nm) or a polychromatic visible light delivered by a halogen lamp. The photoinitiating ability of some of these systems is even better than that of the well-known camphorquinone based systems and the commercial bisacylphosphine oxide type I photoinitiator, unambiguously showing their outstanding performance. The structure/reactivity relationships as well as the particular role played by the position of the aminothiazo-substituent in the ATNDs is revealed by mechanistic studies using steady state photolysis, cyclic voltammetry, fluorescence, laser flash photolysis, and electron spin resonance spin trapping techniques. © 2016 The Royal Society of Chemistry.

Vol. 175, pp. 193-202 
article DOI URL 
Abstract: We report here a facile, mild and low cost aqueous-based synthesis for the production of high quality CdZnS and Cu-doped CdZnS quantum dots (QDs). We demonstrate that the photoluminescence (PL) of the Cu-doped CdZnS nanocrystals could be tuned in the whole visible spectrum via the stoechiometric ratio of Cd/Zn precursors in the host CdZnS QDs and by tuning the particle size. By optimization of the experimental conditions (Cd/Zn ratio, reaction time, pH,...) and by varying the surface ligand, pure and highly emissive Cu:CdZnS QDs could be prepared. Moreover, by the growth of a ZnS shell around the Cu:CdZnS core, Cu:CdZnS/ZnS QDs with a PL quantum yield (PL QY) of 42% were constructed, which is the highest PL QY reported to date for Cu-doped CdZnS QDs prepared in aqueous solution. The optical properties and structure of the obtained dots were characterized by UV-visible spectroscopy, steady-state and time-resolved PL spectroscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Cu:CdZnS/ZnS QDs were subjected to various treatments such as long-term UV illumination, storage in biological buffers or pH changes, which are usually detrimental to QDs PL. No marked deterioration in PL properties during the previously described degradation processes was observed, thus indicating the high stability of the dots prepared. Due to their good water dispersibility and stability, the Cu:CdZnS/ZnS QDs developed herein can be a promising candidate for biolabelling applications. © 2016 Elsevier B.V. All rights reserved.

Vol. 7(39), pp. 6084-6093 
article DOI URL 
Abstract: Methyl methacrylate (MMA) and glycidyl methacrylate (GMA) were copolymerized by photocatalyzed atom transfer radical polymerization under the visible light irradiation of a compact blue LED lamp, using bis(1,10-phenanthroline)copper(i) as the photocatalyst. The polymerization was found to be all the more fast that the molar fraction of GMA was high. The same effect was observed when GMA was replaced by cyclohexene oxide (CHO) as a non-copolymerizable epoxide-containing compound. These results suggested that the epoxide functional group acted as a reducing agent in both cases, contributing to a faster regeneration of the activator form of the catalyst. This assumption was confirmed by UV-visible spectroscopy measurements, which evidenced a faster conversion of Cu(ii) to Cu(i) in the presence of epoxide functional groups. Due to their large excess compared to the catalyst, no degradation of the epoxides was detected during the copolymerization of MMA and GMA, which thus provided well-defined poly(MMA-stat-GMA) copolymers as precursors for further functionalization. The statistical distribution of the epoxide side groups could also be controlled through sequenced additions of the comonomers, in a direct "one-pot" approach. © The Royal Society of Chemistry 2016.

Yang, Q., Lalevee, J. and Poly, J. Development of a Robust Photocatalyzed ATRP Mechanism Exhibiting Good Tolerance to Oxygen and Inhibitors. 2016 Macromolecules (Washington, DC, United States), pp. Ahead of Print-  article  
Abstract: A new photocatalyzed atom transfer radical polymn. (ATRP) procedure starting directly from a copper(II) bromine/phenanthroline (phen) mixt. in the presence of triethylamine as a reducing agent is described. Under the irradn. of a compact blue LED lamp, the polymn. of Me methacrylate (MMA) conducted to PMMAs with narrow mol. wts. distributions (Mw/Mn ∼ 1.10). The good chain end fidelity of the products was validated in subsequent chain-extension expts., using them as macroinitiators, either by conventional thermal ATRP or by photocatalyzed ATRP. The efficient reinitiation under light irradn. was also evidenced by a "light ON/OFF" expt. The resp. effects of several parameters on the polymn. kinetics were studied, including light intensity, the nature of the solvent, the molar ratio of the ligand, and the nature of the counterion. Besides the essential generation of the excited species [Cu(phen)2]+*, which will undergo an oxidative quenching as the key step of this photocatalytic cycle, supplementary investigations by UV-vis spectroscopy revealed an addnl. role of light, which also favored the regeneration of the activator. This complementary contribution may consist in a light-triggered exchange of ligands involving minor Cu(II) species, which absorb light in the blue wavelengths domain and are in equil. with [Cu(phen)2Br]+ as the predominant Cu(II) complex. Interestingly, this photocatalyzed ATRP mechanism exhibited a good tolerance to oxygen and inhibitors, as demonstrated by the efficient synthesis of PMMAs with relatively narrow mol. wts. distributions (Mw/Mn < 1.30) in the presence of air and/or 4-methoxyphenol (MEHQ).

Vol. 5, pp. e16054 
article DOI  
Abstract: Electric and magnetic fields play an important role in both chemical and physical reactions. However, since the coupling efficiency between magnetic fields and electrons is low in comparison with that between electric fields and electrons in the visible wavelength region, the magnetic field is negligible in photo-induced reactions. Here, we performed photo-etching of ZrO2 nano-stripe structures, and identified an etching-property polarisation dependence. Specifically, the etching rate and etched profiles depend on the structure width. To evaluate this polarisation-dependent etching, we performed numerical calculations using a finite-difference time-domain method. Remarkably, the numerical results revealed that the polarisation-dependent etching properties were determined by the magnetic field distributions, rather than the electric field distributions. As nano-scale structures induce a localised magnetic field, the discovery of this etching dependence on the magnetic field is expected to introduce a new perspective on advanced nano-scale structure fabrication.

Vol. 3(19), pp. -

Abstract: Various kinds of zinc oxide (ZnO) nanostructures, such as ZnO nanowires, ZnO nanobelts, ZnO nanosheets, and ZnO nanorods are promising building blocks for nanoscale systems. However, to precisely control the size, shape, and to make a controlled assembly of synthesized ZnO nanostructures are major difficulties in the development of bottom-up devices. To overcome the challenge regarding reproducibility and positioning, a new method is proposed, deep ultra-violet (DUV) direct photo-patterning, to create ZnO micro- and nanostructures. A sol–gel formulation sensitive to DUV light and based on zinc methacrylate precursor is developed, and the photoreactions of zinc methacrylate under DUV light are carefully investigated by in situ spectroscopic ellipsometry, in situ FTIR, and XPS analysis. Then, the sol–gel solution is used as a negative tone resist in DUV lithography to evaluate its performance in producing high-resolution patterns. The results indicate that small patterns from micro- to nanoscale can be obtained in a simple and direct way. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Vol. 7(47), pp. 7316-7324

Abstract: Four dihydroxyanthraquinone derivatives [i.e. 1,2-dihydroxyanthraquinone (12-DHAQ), 1,4-dihydroxyanthraquinone (14-DHAQ), 1,5-dihydroxyanthraquinone (15-DHAQ), and 1,8-dihydroxyanthraquinone (18-DHAQ)], when combined with various additives (e.g. iodonium salt, tertiary amine, N-vinylcarbazole, phenacyl bromide, and 4-cyanopentanoic acid dithiobenzoate), are investigated as photoinitiating systems for free radical photopolymerization [e.g. cross-linked free radical photopolymerization of multifunctional monomers or reversible addition-fragmentation chain transfer (RAFT) photopolymerization of monofunctional monomers] and cationic photopolymerization. 14-DHAQ, 15-DHAQ and 18-DHAQ exhibit good solubility in solvent (acetonitrile) and monomers (methacrylate and epoxide) and demonstrate absorption maxima in the blue light wavelength range, which makes them potential candidates to work under the irradiation of a household blue LED bulb. Among all the investigated dihydroxyanthraquinone derivative-based photoinitiating systems, 18-DHAQ based systems exhibit the highest photoinitiating ability for both free radical and cationic photopolymerization while 12-DHAQ based systems are inefficient. It illustrates that the positions of hydroxyl substituents in the anthraquinone molecule play a significant role in the photoinitiating ability of dihydroxyanthraquinone derivatives. The photochemical mechanisms are investigated by fluorescence, laser flash photolysis, steady state photolysis, and electron spin resonance spin trapping techniques, and the results are in agreement with the relevant photopolymerization efficiency.

Abstract: The cations and radicals produced in aminothiazonaphthalic anhydride derivatives (ATNAs) combined with an iodonium salt, N-vinylcarbazole, amine, or chloro triazine initiate the ring-opening cationic polymerization of epoxides and the free radical polymerization of acrylates under LEDs at 405 or 455 nm. The photoinitiating ability of these novel photoinitiating systems is higher than that of the well-known camphorquinone-based systems. An example of the high reactivity of the new proposed photoinitiator is also provided in resins for 3D-printing using a LED projector@405 nm.

Abstract: A series of conjugated polymers and oligomers previously used in organic photovoltaics and organic light-emitting diodes (OLEDs) have been examined for the first time as photoinitiators of polymerization. They address the present and future challenges facing photopolymerization: requirement of high extinction molar coefficients, absorption over the whole visible spectrum, ability to easily withdraw or release electrons. Interestingly, these compounds initiate the cationic polymerization of epoxides or the free radical polymerization of acrylates upon exposure of the photocurable formulations to a LED emitting at 405 nm. Some of them can potentially operate under blue, green, or red laser diodes. (Figure presented.). © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

Abstract: The novel role of metal-based complexes as photoinitiator catalysts fits well into the concept of green chemistry, as it realizes the activation of polymer synthesis processes by visible light that are abundant in the solar light and allows the marked reduction of photoinitiator amount in the systems. In the present paper, a series of iron complexes (FeC_x) with various ligands have been proposed as new photoinitiator catalysts to initiate the cationic polymerization of epoxides or the free radical polymerization of acrylates upon a near-UV or visible-light LED exposure. The ligands play an important role on the light absorption properties and the photoinitiation ability of the iron complexes. In combination with one or two additives, FeC_x are capable to efficiently generate radicals, cations, and radical cations through an oxidative or a reductive path. Two of the newly developed FeC_x-based photoinitiating systems exhibited comparable photoinitiation efficiency with the commercial Type I photoinitiator bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide (BAPO). Owing to the photocatalytic effect, remarkable photoinitiation efficiencies have been achieved by using very low concentration of iron complexes (0.02 wt %) in the systems. The involved photochemical mechanisms have been studied using electron spin resonance spin trapping, steady state photolysis, cyclic voltammetry, and laser flash photolysis techniques. © 2016 WILEY-VCH Verlag GmbH & Co.

Vol. 73(2), pp. 493-507 
article DOI URL 
Abstract: Abstract: A carbazole-bound ferrocenium salt [i.e., (η6-Carbazole) (η5-cyclopentadienyl) iron hexafluorophosphate—FS] is proposed as an efficient photoinitiator for the cationic ring-opening polymerization of epoxides under air upon the exposure to a near-UV LED at 385 nm or a visible LED at 405 nm. When using this ferrocenium salt FS (0.2 wt%)/diphenyliodonium hexafluorophosphate or FS (0.2 wt%)/diphenyliodonium hexafluorophosphate/N-vinylcarbazole, final epoxide conversions of 55–66 % can be obtained after 800 s of irradiation at 385 or 405 nm. Reference cationic photoinitiators (i.e., diphenyliodonium hexafluorophosphate; 9-(4-hydroxyethoxyphenyl) thianthrenium hexafluorophosphate and triphenylsulfonium hexafluorophosphate) are unable to initiate the epoxide polymerization under the same conditions. The photochemical mechanisms for the formation of the initiating species are studied using steady-state photolysis, cyclic voltammetry, laser flash photolysis and electron spin resonance spin-trapping techniques. Molecular orbital calculations help to describe the absorption properties and the initiation step. The performance attained when using FS alone is really promising for applications under soft near-UV or visible light-emitting diode irradiation.

Abstract: Photoinitiating systems consisting of a highly porous iron(III)-based metal-organic framework (MOF), an iodonium salt, and N-vinylcarbazole are developed to initiate the free radical promoted cationic polymerization of epoxides under air and the free radical polymerization of acrylates in laminate upon exposure to near UV (385 nm) or visible (405 nm) light-emitting diodes. These systems present a satisfactory initiating ability. Among the five tested iron carboxylate MOFs exhibiting different compositions and topologies, the flexible microporous iron(III) terephthalate MIL53 is particularly interesting, leading to a final conversion of 58% for the ring-opening polymerization of epoxides. This provides the possibility of designing MOF/polymer composite materials with enhanced mechanical properties through the in situ incorporation of the MOF structure during the photopolymerization process. © 2016 by WILEY-VCH Verlag GmbH & Co.

Vol. 6(1), pp. 1501588 (9pages)

Abstract: Hard carbons are considered among the most promising anode materials for Na-ion batteries. Understanding their structure is of great importance for optimizing their Na storage capabilities and therefore achieving high performance. Herein, carbon nanofibers (CNFs) are prepared by electrospinning and their microstructure, texture, and surface functionality are tailored through carbonization at various temperatures ranging from 650 to 2800 °C. Stepwise carbonization gradually removes the heteroatoms and increases the graphitization degree, enabling us to monitor the corresponding electrochemical performance for establishing a correlation between the CNFs characteristics and Na storage behavior. Outstandingly, it is found that for CNFs carbonized at above 2000 °C, a single voltage Na uptake plateau at ≈0.1 V with a capacity of ≈200 mAh g-1. This specific performance may be nested in the higher degree of graphitization, lower active surface area, and different porous texture of the CNFs at such temperatures. It is demonstrated via the assembly of a CNF/Na2Fe2(SO4)3 cell the benefit of such CNFs electrode for enhancing the energy density of full Na-ion cells. This finding sheds new insights in the quest for high performance carbon based anode materials.

Novel naphthalimide-amine based photoinitiators operating under violet and blue LEDs and usable for various polymerization reactions and synthesis of hydrogels 2016 Polym. Chem.
Vol. 7(2), pp. 418-429

Abstract: A series of naphthalimide derivatives containing tertiary amine groups (DNNDs) have been prepared. Some of these derivatives (e.g. DNND3, DNND4 and DNND5) exhibit interesting shifted absorption so that they can be utilized as versatile photoinitiators upon exposure to various violet and blue LEDs (385, 405, 455 and 470 nm). They are particularly efficient for the cationic photopolymerization of an epoxide and the free radical photopolymerization of an acrylate. The thiol-ene photopolymerization, as well as the synthesis of interpenetrating polymer networks (of epoxide/acrylate blend) IPNs, is feasible. Remarkably, the production of hydrogels can also be easily achieved using a DNND derivative after inclusion in a cyclodextrin cavity. The photochemical mechanisms have been comprehensively investigated by steady state photolysis, Electron Spin Resonance (ESR), fluorescence, electrochemistry and laser flash photolysis and discussed in detail.

Zlotea, C., Oumellal, Y., Provost, K. and Ghimbeu, C.M. Experimental Challenges in Studying Hydrogen Absorption in Ultrasmall Metal Nanoparticles 2016 Frontiers in Energy Research
Vol. 4, pp. 24 
article DOI URL 
Abstract: Recent advances on synthesis, characterisation and hydrogen absorption properties of ultra-small metal nanoparticles (defined here as objects with average size ≤ 3 nm) are briefly reviewed in the first part of this work. The experimental challenges encountered in performing accurate measurements of hydrogen absorption in Mg- and noble metal-based ultra-small nanoparticles are addressed.
The second part of this work reports original results obtained for ultra-small bulk immiscible Pd-Rh nanoparticles. Carbon supported Pd-Rh nanoalloys in the whole binary chemical composition range have been successfully prepared by liquid impregnation method followed by reduction at 300 °C. EXAFS investigations suggested that the local structure of these nanoalloys is partially segregated into Rh-rich core and Pd-rich surface coexisting within the same nanoparticles.
Downsizing to ultra-small dimensions completely suppresses the hydride formation in Pd-rich nanoalloys at ambient conditions, contrary to bulk and larger nanosized (5-6 nm) counterparts. The ultra-small Pd90Rh10 nanoalloy can absorb hydrogen forming solid solutions under these conditions, as suggested by in situ XRD. Apart from this composition, common laboratory techniques such as, in situ XRD, DSC and PCI failed to clarify the hydrogen interaction mechanism : either adsorption on developed surfaces or both adsorption and absorption with formation of solid solutions. Concluding insights were brought by in situ EXAFS experiments at synchrotron: ultra-small Pd75Rh25 and Pd50Rh50 nanoalloys absorb hydrogen forming solid solutions at ambient conditions. Moreover, the hydrogen solubility in these solid solutions is higher with increasing Pd content and this trend can be understood in terms of hydrogen preferential occupation in the Pd-rich regions, as suggested by in situ EXAFS. The Rh-rich nanoalloys (Pd25Rh75 and Pd10Rh90) only adsorb hydrogen on the developed surface of ultra-small nanoparticles. In summary, in situ characterization techniques carried out at large scale facilities are unique and powerful tools for in-depth investigation of hydrogen interaction with ultra-small nanoparticles at local level.

Vol. 37(10), pp. 840-844 
article DOI URL 
Abstract: The photochemical and electrochemical investigations of commercially available, safe, and cheap fluorescent brighteners, namely, triazinylstilbene (commercial name: fluorescent brightener 28) and 2,5-bis(5-tert-butyl-benzoxazol-2-yl)thiophene, as well as their original use as photoinitiators of polymerization upon light emitting diode (LED) irradiation are reported. Remarkably, their excellent near-UV–visible absorption properties combined with outstanding fluorescent properties allow them to act as high-performance photoinitiators when used in combination with diaryliodonium salt. These two-component photoinitiating systems can be employed for free radical polymerizations of acrylate. In addition, this brightener-initiated photopolymerization is able to overcome oxygen inhibition even upon irradiation with low LED light intensity. The underlying photochemical mechanisms are investigated by electron-spin resonance-spin trapping, fluorescence, cyclic voltammetry, and steady-state photolysis techniques.

Vol. 88(10)European Physical Journal B, pp. - 
article URL 
Abstract: We report experimental results from frequency-domain spectroscopy on graphene (GE) filled polyvinylidene difluoride trifluoroethylene P(VDF-TrFE). The dielectric properties of these polymer nanocomposites (GPN) were investigated over a broad range of frequency (from 102 Hz to a few GHz) and a broad range of temperature (from 150 K to 370 K) by using two measurement techniques: impedance spectroscopy and asymmetrical stripline. Care is needed in relating the GE content to the dielectric properties of GPN since the addition of GE to P(VDF-TrFE) can result in a nonmonotonic permittivity change. At low frequency (&lt;1 MHz) the relaxation spectra is not Debye like but is characterized with a broad relaxation time distribution especially at low temperatures. This effect originates from the freezing process of dipoles and Maxwell-Wagner-Sillars (MWS) interfacial polarization. Additionally, a fit of the effective permittivity versus GE content suggests that our data are in accord with the two-exponent phenomenological percolation equation (TEPPE). These experimental results draw attention to the importance of the large surface area of the GE nanoparticles in controlling the interface between the GE flakes and the polymer phase. © 2015, EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Abstract: Abstract The denitrification process occurring in wastewater treatment plants (WWTPs) is responsible for nitrous oxide (N2O) and nitric oxide (NO) emissions. These compounds indirectly lead to the global warming. In this study, we investigated the impact of the temperature on N2O and NO emissions. Experiments were achieved at PH 7 in a batch reactor with acetate as the carbon source. The nitrogen source was nitrates (NO3−) and the COD/N ratio was set to three. Results showed that NO and N2O emissions increased when the temperature decreased. NO emissions appeared only at 10 °C and 5 °C, with respectively 8% and 18% of the total denitrified nitrogen. N2O emissions increased from 13 to 40 then 82% of the total denitrified nitrogen, respectively at 20, 10 and 5 °C. Several hypotheses were suggested to explain these results: a general enzymatic slow down, enzymatic inhibitions, electron donor competition between the different enzymes and metabolic pathway alterations.

Airoudj, A., Ploux, L. and Roucoules, V. Effect of Plasma Duty Cycle on Silver Nanoparticles Loading of Cotton Fabrics for Durable Antibacterial Properties 2015 Journal of Applied Polymer Science
Vol. 132(1), pp. 41279 
article DOI  
Abstract: A facile method for strongly anchoring silver nanoparticles (AgNPs) onto cotton fabrics was reported. It consists in loading AgNPs onto the cotton fiber preliminary coated with maleic anhydride plasma polymer layer. This results in hydrolyzis and ring opening of anhydride groups followed by electrovalent bonding of silver ions and reduction in NaBH4. X-ray photoelectron spectroscopy (XPS), infrared spectroscopy, and scanning electron microscope (SEM) were used to analyze changes in the surface chemical composition and morphology of the plasma modified fibers. The presence of AgNPs was confirmed by UV-Visible spectroscopy and atomic force microscopy (AFM) images. Remarkably, varying plasma duty cycle for plasma polymer deposition allowed tailoring the amount of loaded AgNPs. The highest amount of AgNPs was obtained with the lowest duty cycle values. Qualitative tests showed that silver containing plasma modified cotton displays significant antibacterial activity. (C) 2014 Wiley Periodicals, Inc.

Abstract: A series of new bipyrimidine-based chromophores have been prepared presenting alkoxystyryl donor groups carrying aliphatic chains in the 3,4, 3,5 or 3,4,5 positions, connected to electron-accepting 2,2?-bipyrimidine cores. Their linear and nonlinear optical properties were investigated as well as their mesomorphic properties by various techniques (light-transmission measurements, polarized-light optical microscopy, and differential scanning calorimetry measurements). Only two derivatives, BPM-3,4-C12 and BPM-3,4-C16, were found to exhibit liquid-crystalline behavior with the formation of lamella-columnar phases and/or hexagonal columnar phases over large temperature ranges. Small-angle X-ray scattering analysis allowed proposing a stacking model inside the mesophase in which the molecules are interdigitated alternatively along their long axis and their short axis to form columns. Dielectric measurements were performed as a function of the temperature, showing the centrosymmetric nature of the mesophases. Large quadratic hyperpolarizabilities have been measured for the individual mesogens in solution by using hyper-Rayleigh scattering. These chromophores exhibit also cubic nonlinear optical properties, revealing relatively large two-photon absorption cross sections. The nonlinear optical properties in the liquid crystalline state of compounds BPM-3,4-C12 and BPM-3,4-C16 have been studied by wide-field second-harmonic generation and two-photon fluorescence microscopy, confirming centrosymmetry for these achiral mesogens and the excellent third-order nonlinearity for multiphoton imaging.

Small-angle X-ray scattering analysis allowed proposing a stacking model inside the mesophase in which the molecules are interdigitated alternatively along their long axis and their short axis to form columns. Dielectric measurements were performed as a function of the temperature, showing the centrosymmetric nature of the mesophases. Large quadratic hyperpolarizabilities have been measured for the individual mesogens in solution by using hyper-Rayleigh scattering. These chromophores exhibit also cubic nonlinear optical properties, revealing relatively large two-photon absorption cross sections. The nonlinear optical properties in the liquid crystalline state of compounds BPM-3,4-C12 and BPM-3,4-C16 have been studied by wide-field second-harmonic generation and two-photon fluorescence microscopy, confirming centrosymmetry for these achiral mesogens and the excellent third-order nonlinearity for multiphoton imaging.

Abstract: Transition-metal complexes containing stimuli-responsive systems are attractive for applications in optical devices, photonic memory, photosensing, as well as luminescence imaging. Amongst them, photochromic metal complexes offer the possibility of combining the specific properties of the metal centre and the optical response of the photochromic group. The synthesis, the electrochemical properties and the photophysical characterisation of a series of donor-acceptor azobenzene derivatives that possess bipyridine groups connected to a 4-dialkylaminoazobenzene moiety through various linkers are presented. DFT and TD-DFT calculations were performed to complement the experimental findings and contribute to their interpretation. The position and nature of the linker (ethynyl, triazolyl, none) were engineered and shown to induce different electronic coupling between donor and acceptor in ligands and complexes. This in turn led to strong modulations in terms of photoisomerisation of the ligands and complexes.

Vol. 36(12)Polymer Composites, pp. 2255-2264 
article DOI URL 
Abstract: Hyperbranched poly(amidoamine)s (PAMAMs), exhibiting various levels of hydrophilicity, were used as modifiers for melamine urea formaldehyde (MUF) adhesives. The modification was achieved either with or at expense of sodium hydroxide during the last pH adjustment. Their apparent co-condensability was expected from the measured gel times and further proved using Fourier transform infrared (FTIR) spectroscopy as well as 13C nuclear magnetic resonance (13C NMR). Utilization of these structures as modifiers for MUF, which are frequently used in particleboards production, resulted in manifold advantages. Considering the economic point of view, their use is more practical and cheaper with respect to dendritic structures. Additionally, their application in finite quantities as final additives, either immediately before the final use or at the last stage of preparation, yielded considerable upgrading of the dry internal bond (IB) strength of the produced particleboards. The improvement was extended to the resistivity to hydrolytic degradation as revealed by the wet IB strength and thickness swelling. The results were explained on the light of an extensive investigation on the resins using thermomechanical analysis (TMA) while taking into account the relevant hydrophilicity and degree of branching of each hyperbranched structure. © 2014 Society of Plastics Engineers.

Vol. 201(0), pp. 43-49 
article URL 
Abstract: Abstract Induction heating has been used to thermally treat mesostructured TiO2 with hexagonal 2D structure prepared by a combined Liquid Crystalline Template (LCT) and Evaporation Induced Self-Assembly (EISA) synthesis method. Induction treatment induces the decomposition of the structuring agent P123 and the formation of anatase. Highly ordered mesoporous titania with a semi crystalline framework can be obtained very fast, i.e. 5 min at 460 °C or 15 min at 300 °C. The recovered materials have similar structural, textural properties and photoactivity towards the decomposition of methyl orange than the mesostructured TiO2 obtained after ethanol extraction followed by a calcination at 400 °C in a conventional furnace.

Vol. 649, pp. 1-10 
article DOI  
Abstract: Zn–TiO2 mesoporous oxides have been prepared by the mechanical milling of zinc acetate either with a surfactant free mesoporous titania or with the hybrid mesophase, in that case the surfactant is still present inside the pores. After calcination in a muffle furnace or by induction, the obtained materials have been characterized in details by SAXS, XRD, EDX, nitrogen adsorption-desorption, XPS and UV spectroscopy. The photocatalytic activity of the mesoporous oxides has also been tested on the photodegradation of methyl orange. The results show that the presence of surfactant favors the zinc dispersion, prevents from the formation of zincite and slows down the crystallization of anatase. The recovered materials present a mesopore arrangement with low crystallized walls. As a consequence, by comparison with the pure mesoporous titania having semi-crystalline anatase framework, their photocatalytic efficiency is decreased. By contrast, when zinc acetate is mechanically milled with the free surfactant mesoporous TiO2, agglomerated particles were observed by EDX and TEM and the zincite phase ZnO was detected by XRD. Studies of the Kubelka-Munk function revealed the presence of two band gap energies corresponding to 3.2 and 2.9 eV. The appearance of ZnO in the materials and the reduction of the band gap give a capacity for the photodegradation of methyl orange slightly higher than the one of the pure mesoporous titania with semi crystalline framework.

Vol. 134, pp. 73-80 
article URL 
Abstract: Abstract Quantity, orientation, conformation and covalent linkage of naturally cell adhesive proteins adsorbed or covalently linked to a surface, are known to influence the preservation of their subsequent long term cell adhesion properties and bioactivity. In the present work, we explore two different strategies for the covalent linking of plasma fibronectin (pFN) - used as a cell adhesive model protein, onto a polystyrene (PS) surface. One is aimed at tethering the protein to the surface in a semi-oriented fashion (via one of the 4 free thiol reactive groups on the protein) with a heterofunctional coupling agent (SSMPB method). The other aims to immobilize the protein in a more random fashion by reaction between the abundant pendant primary amine bearing amino acids of the pFN and activated carboxylic surface functions obtained after glutaric anhydride surface treatment (GA method). The overall goal will be to verify the hypothesis of a correlation between covalent immobilization of a model cell adhesive protein to a PS surface in a semi-oriented configuration (versus randomly oriented) with promotion of enhanced exposure of the protein's cell binding domain. This in turn would lead to enhanced cell adhesion. Ideally the goal is to elaborate substrates exhibiting a long term stable protein monolayer with preserved cell adhesive properties and bioactivity for biomaterial and/or cell adhesion commercial plate applications. However, the initial restrictive objective of this paper is to first quantitatively and qualitatively investigate the reversibly (merely adsorbed) versus covalently irreversibly bound protein to the surface after the immobilization procedure.

Vol. 33(4), pp. 260-276 
article DOI  
Abstract: Although pyrotechnic performance is fundamental, the strong mechanical and electrostatic intrinsic sensitivities of nanothermite energetic composites represent an obstacle to their development. The addition of a ternary component to the classical binary energetic composite appears to be a promising idea to overcome the problem. A carbon black additive (V3G) was used on a WO3/Al nanothermite. The effect of the pristine and modified carbon particles on the mechanical and electrical sensitivities of the composites was measured together with the pyrotechnic properties. The results show a complete desensitization to friction with a ball-milled carbon when the combustion velocity is slightly reduced.

Abstract: The precise engineering of ultrathin nanofilms with variable functionality remains an unmet challenge in nanotechnology. We report a strategy for generating free-standing nanomembranes based on the selective chemical vapor deposition polymerization of functional [2.2]paracyclophanes on micropatterned self-assembled monolayers of alkanethiolates on gold. This fabrication strategy can yield microstructured nanofilms that are between 2 and 5 nm thick. Subsequent release from the substrate results in free-standing nanoscale membranes with controlled pore size and geometry. The process allows for modification of important functional parameters, such as ultrasmall membrane thickness, membrane pore geometry, and chemical functionality.

Abstract: Abstract The toxicity of quantum dots (QDs) has been commonly attributed to the release of metal ions from the core as well as to the production of reactive oxygen species. However, the information related to the stability of the nanoparticles are relatively scarce although this parameter may strongly influence their toxicity. The stability of aminosilane-capped ZnO QDs, here used as model nanoparticles, was investigated by inductively coupled plasma-optical emission spectrometer (ICP-OES) and whole cell biosensors using a dialysis setup to separate the QDs from the leaked Zn2+ ions. The integrity of the ZnO QDs appeared strongly affected by their dilution in aqueous medium, whereas the nanoparticles were slightly stabilized by bacteria. Our results demonstrate some inadequacy between the implementation and use of whole cell biosensors, and the monitoring of metal release from QDs.

Abstract: The thermal insulation behavior of ordered mesoporous silica SBA-15 aggregates heat treated at 300 C-a similar to was studied. An important decrease in the effective thermal conductivity according to the increase of the apparent density was observed. A thermal conductivity value less than 25 mW.m(-1).K-1 was reached during the compaction phenomenon. Results of thermal conductivity were correlated to the electron microscopy observations and physicochemical data (X-ray diffraction, adsorption/desorption of nitrogen volumetric measurements). These thermal properties make these materials very promising for thermal insulation applications, especially with values inferior to the thermal conductivity of air.

Vol. 91(0), pp. 458-467 
article URL 
Abstract: Abstract Graphite is a widely used anode electrode material for Li-ion batteries. When the anode is polarized to a low potential, the electrolyte reduction products form a film called SEI (Solid Electrolyte Interphase) playing a crucial role in the reversibility of the electrochemical cycling. This SEI layer is preferentially formed through the carbon edge planes that can be divided into two main categories with different reactivity: zigzag and armchair edges. Main objective of this work is to experimentally study the influence of the carbon edge atoms configuration on SEI formation and consequently on the electrochemical performance of the electrode. In this aim, a preferential etching method based on oxygen or water gasification was first developed to control zigzag and armchair edge concentration. A range of graphite samples having different reactivity could be prepared and electrochemically tested. Experimental results point out that the carbon edge atom configuration is an important parameter controlling the reactivity of the graphite toward the electrolyte. In particular, a carbon material having a high concentration of zigzag edge carbon atoms is not recommended for the formation of an ad hoc SEI. As a result, the co-intercalation of solvent is enhanced leading to an exfoliation tendency of the electrode.

Abstract: Abstract This work focuses on the study of the hydration phenomenon operating in Na-mordenite membranes during the conditioning step (stabilisation of filtration properties). First, experimental (filtration of pure water) tests are carried out immediately after putting the membrane in its casing and until the stabilization of the membrane permeation flux. The evolution of the hydraulic permeability shows that there are two separate steps during the conditioning of the membrane. A numerical approximation of the hydraulic permeability during the conditioning step was carried out. The first part of the equation expresses a fast decrease in the membrane's permeability during the beginning of the conditioning step (several hours). This behaviour is attributed to a surface hydration of the membrane and also to a modification of the crystalline framework. The second one is a slower phenomenon that takes place until the end of the conditioning step. It is attributed to the (intra-crystalline) hydration of micropores.

The results reveal that the binder can react with the fuel to form CO2, and that its total reduction capacity increases with temperature. XRD characterizations performed on the binder (on the fresh and after several cycles) show a shift of the diffraction peaks of NiAl2O4 toward the ones of gamma-alumina, which can be attributed to a progressive decomposition of NiAl2O4 to alumina and NiO.

Abstract: This work aims to study the evolution of NiO/NiAl2O4 redox performance with CO as fuel for Chemical Looping Combustion (CLC) applications. The oxygen carrier (OC) was investigated under alternating oxidizing and reducing conditions in a fixed bed reactor simulating the cyclic conditions of CLC. The study of the operating temperature influence reveals that total reduction capacity increases with temperature, due to the reaction of the binder NiAl2O4. Regeneration step performed under low oxygen concentration (5 vol.%) shows that the decrease in total reduction capacity during multiple cycles is minimized and the purity of produced CO2 is higher. Therefore, carrying out the regeneration step at lower oxygen concentrations can increase oxygen carrier lifetime. Characterization studies revealed the formation of a nickel rich layer at the surface (up to 20 mu m thick at 900 degrees C) and a partial sintering of particles regenerated under 20 vol.% of oxygen. However, these phenomena are not observed on the particles regenerated under low oxygen concentration. The formation of this layer can be explained by the fact that nickel oxidation is carried out by migration of Ni2+ cations through the layer of NiO initially oxidized at the surface of the particle, the layer becomes thicker during cycles, because NiO does not return to its initial position. At higher temperature, the diffusion velocity increases and therefore the layer formed is thicker. Specific surface area of the oxygen carrier decreases as cycles number increases from 9.4 m(2)/g for the fresh material to 4.4 and 2.3 m(2)/g after thirty cycles at 750 degrees C and 900 degrees C respectively. The same trend is observed for porous volume. However, the decrease is lower when particles are regenerated under low oxygen concentration (6 m(2)/g). (C) 2015 Elsevier Ltd. All rights reserved.

Abstract: An essential yet never addressed parameter for the control of bacteria on functionalized biomaterial is surely the accessibility and heterogeneity of the functional groups immobilized on the surface. In this context, we investigated the colonization (Escherichia coli K12, Staphylococcus epidermidis RP62A) of precisely engineered surfaces revealing various densities of NH2 and CH3 functional groups. We demonstrated for the first time nonlinear relationships between the NH2/CH3 surface fraction and the quantity of adhered, adhering or detaching bacteria. Plateaus and transition zones were related to the range of NH2/CH3 surface fraction offering stability or sharp variation in bacterium/surface interactions. The nonlinear behavior was attributed to the discrete distribution of positive charges revealed by the bacterial membrane in the continuum of negative charges resulting from the phospholipids, which may correlate with one single specific distribution of positive NH3+ charges on the material surface, because of electrostatic, repulsive interactions occurring at the local, molecular scale.

Abstract: Smart detection systems for explosive sensors are designed both to detect explosives in the air at trace level and identify the threat for a specific response. Following this need we have succeeded in using microthermal analysis to sensitively identify and discriminate between RDX and PETN explosive vapors at trace level. Once the explosive vapor is trapped in a porous material, heating the material at a fast rate of 3000 K/s up to 350 degrees C will result in a thermal pattern specifically corresponding to the explosive and its interaction with the porous material. The explosive signatures obtained make it possible to simultaneously identify the presence and the nature of the explosive vapor in just a few milliseconds. Therefore, this also allows the development of multitarget devices using porous material for capturing the vapor combined with microthermal analysis for fast detection and identification. So far it is the first time that chip calorimetry has been used to characterize and identify explosives in vapor state.

Abstract: Abstract The present investigation aims to examine the influence of textural, structural and chemical properties of biomass chars on the CO2 gasification rate. Various lignocellulosic biomass chars were prepared under the same conditions. Different analytical techniques were used to determine the char properties such as Scanning Electronic Microscopy, nitrogen adsorption manometry, Raman spectroscopy and X Ray Fluorescence. Gasification tests were carried out in a thermobalance under 20% CO2 in nitrogen at 800 °C.

Vol. 66(0), pp. 282-290 
article URL 
Abstract: Abstract Nitrogen-doped carbon materials (NCMs) were obtained by amination of tannin by hydrothermal carbonisation (HTC). NCMs presented different morphologies depending on the amination method: (i) powders by HTC of tannin in a concentrated aqueous ammonia solution; (ii) gels without using any crosslinker by HTC in distilled water of tannin first dissolved in concentrated ammonia and then evaporated. Whatever the method, (i) or (ii), HTC was carried out at different temperatures: 180, 190, 200, 210 or 220 °C, with further pyrolysis at 900 °C under nitrogen. The morphology and chemical composition of the resultant materials were discussed. We compared our results with those reported in the open literature and we concluded that HTC of tannin in a concentrated aqueous ammonia solution allowed obtaining outstanding materials because they have both surface areas, higher than 500 m2 g−1, and high N content, around 8 wt.%.

Vol. 90(0), pp. 63-74 
article URL 
Abstract: Abstract Aminated tannin submitted to hydrothermal treatment led to nitrogen-doped gels in the absence of any crosslinker. Such gels were subcritically, freeze- or supercritically dried to obtain organic xerogels, cryogels and aerogels, respectively, having nitrogen contents between 3.0 and 3.7 wt. %. After pyrolysis at 900°C, the materials presented nitrogen contents ranging from 1.9 to 3.0 wt. %, and surface areas as high as 860, 754 and 585 m2 g-1 for carbon aerogels, cryogels and xerogels, respectively. They all displayed micropores associated with different mesopore volumes, depending on both drying method and initial dilution of the precursor. When tested as supercapacitor electrodes, these carbon gels presented outstanding specific and normalised capacitances, up to 387.6 F g-1 and 69.5 μF cm-2, respectively, at a scan rate of 2 mV s-1 in 4 mol L-1 H2SO4 aqueous solution. These performances are higher than those obtained with high apparent surface area-activated carbons, as the measured capacitances are indeed among the highest ever reported. The influence of nitrogen- and oxygen-based moieties was investigated, and optimal N and O contents of 2-3 wt. % and 17-18 wt. %, respectively, were observed.

Vol. 70, pp. 332-340 
article DOI  
Abstract: Six porous carbon materials, produced by hydrothermal treatment of flavonoid tannin and subsequent carbonization at 1173 K, were tested as electrodes of supercapacitors. Four of these carbons were doped with nitrogen by putting tannin in contact with ammonia before or during the hydrothermal treatment. The pyrolyzed hydrothermal carbons had moderate surface areas, within the range 442-684 m(2) g(-1), and nitrogen contents ranging from 0.7 to 8.0 wt.%. Specific capacitances as high as 320 F g(-1) and normalized capacitances as high as 58 mu F cm(-2) were measured at 2 mV s(-1). These performances are comparable with those obtained with high surface area-activated carbons, whereas, normalized capacitances values are among the highest ever reported. Mesostructuration, within the range 3-13 nm, of these materials appears to be a good strategy to improve their electrochemical performances at higher scan rates. We confirmed the beneficial role of oxygen up to 18 wt.%, while an optimum in nitrogen content exists from 3 to 6 wt.%. (C) 2015 Elsevier B.V. All rights reserved.

Vol. 77, pp. 364-374 
article URL 
Abstract: Abstract The present study deals with the preparation of carbonaceous materials from flavonoid tannin by a two-step process: hydrothermal carbonisation (HTC) at 180 °C in aqueous solution, followed by pyrolysis at 900 °C. Whereas such process and the resultant materials have been described elsewhere (Braghiroli et al., 2014), two modifications of the HTC step were introduced and investigated for the first time: 1) pH reduction, by para-toluenesulphonic acid addition, as catalyst of tannin rearrangement reactions; 2) silver nitrate addition as nucleating agent by silver metal nanoparticles formation. Carbon from tannin simply pyrolysed at 900 °C (i.e., without HTC step) was also prepared and used as a reference material. The impacts of these modifications on yield, composition, porosity and nanotexture of the resultant carbon materials were investigated in detail. The carbons produced at low pH were monolitic and had te highest surface areas, up to 800 m2 g−1, with the same microporous size distribution as the material prepared at non-modified pH. The presence of silver produced a decrease and a homogenisation of the microsphere particle size with an increase of the yield. Adding H+ and Ag+ both produced more crystalline carbons, although HTC itself at non-modified pH produced less crystalline carbon compared to the reference material.

Abstract: Recently, it was shown that the microstructure of a maleic anhydride plasma polymer (MAPP) could be tailored ab initio by adjusting the plasma process parameters. In this work, we aim to investigate the ability of cellulose nanocrystals (CNCs) to induce topographical structuration. Thus, a new approach was designed based on the deposition of MAPP on CNCs model surfaces. The nanocellulosic surfaces were produced by spin-coating the CNC suspension on a silicon wafer substrate and on a hydrophobic silicon wafer substrate patterned with circular hydrophilic microsized domains (diameter of 86.9 ± 4.9 ?m), resulting in different degrees of CNC aggregation. By depositing the MAPP over these surfaces, it was possible to observe that the surface fraction of nanostructures increased from 20% to 35%. This observation suggests that CNCs can act as nucleation points resulting in more structures, although a critical density of the CNCs is required.

Vol. 12(11), pp. 1220-1230 
article DOI  
Abstract: The understanding concerning structure formation during maleic anhydride plasma polymerization is focused based on growth kinetics study and chemical force titration through atomic force microscopy. Growth kinetics suggested that beads were formed initially and acted as intermediate for the random formation of needle-like and branched structures. The structures surface area followed a linear trend, except for the beads surface area that levels-off. Chemical force titration revealed that all the samples exhibited two pK(a) values, but the shifting of the values and the different trends indicated differences in the global chemistry of the films, associated to the presence of the structures.

Abstract: Abstract The present study demonstrates an optimized procedure for mass production of EMT-type structure zeolite. The introduction of triethanolamine (TEA) in the synthesis gel leads to the formation of larger and agglomerated nanocrystals. The obtained particles can be easily recovered from the reaction medium by filtration and washing without the use of high speed centrifugation. This simple approach paves a new way for energy-efficient synthesis of nanoporous materials for potential industrial applications.

Abstract: Abstract Spherical mesoporous silica particles were successfully prepared by using non-ionic amphiphilic di-block co-polymers CnH2n+1-(EO)x-OH as templates and tetraethylorthosilicate (TEOS) as silica precursor. The synthesized mesoporous silica materials were characterized by X-ray diffraction (XRD), N2 adsorption-desorption and scanning electron microscopy (SEM) techniques. CO2 adsorption at 273 K was evaluated by a volumetric method, and the CO2 sorption behavior was described by applying both Langmuir and Freundlich equations. Results indicate a high adsorption capacity of CO2 (5-9 mmol/g), depending essentially on the porous texture of the materials. An adsorption kinetic model was used to describe the adsorption of CO2 over template-free mesoporous siliceous materials. A good agreement with experimental data was found.

Abstract: For many years it has been a major challenge to regenerate damaged tissues using synthetic or natural materials. To favor the healing processes after tendon, cornea, muscle, or brain injuries, aligned collagen-based architectures are of utmost interest. In this study, we define a novel aligned coating based on a collagen/alginate (COL/ALG) multilayer film. The coating exhibiting a nanofibrillar structure is cross-linked with genipin for stability in physiological conditions. By stretching COL/ALG-coated polydimethylsiloxane substrates, we developed a versatile method to align the collagen fibrils of the polymeric coating. Assays on cell morphology and alignment were performed to investigate the properties of these films. Microscopic assessments revealed that cells align with the stretched collagen fibrils of the coating. The degree of alignment is tuned by the stretching rate (i.e., the strain) of the COL/ALG-coated elastic substrate. Such coatings are of great interest for strategies that require aligned nanofibrillar biological material as a substrate for tissue engineering.

Abstract: Imogolite is usually formed by means of a three-step process involving the use of large amounts of water with long crystallization times and low yields, preventing large-scale synthesis. These drawbacks can be overcome by synthesis in the presence of fluoride, an approach which has
been demonstrated to be suitable for the synthesis of other phyllosilicates. In the present study, the nature of the Al and Si sources, the Al/Si molar ratio, the volume of H2O for the redispersion of the gel after desalination, the F/Si molar ratio, as well as the crystallization
temperature and time have been varied to investigate their role in the crystallization of imogolite. The structural properties of the as-synthesized samples were characterized by X-ray diffraction, infrared spectroscopy, and 29Si, 27Al, and 19F magic angle
spinning nuclear magnetic resonance spectroscopy. The results show that the imogolite nanotubes can be prepared with high yields (>55%) from AlCl3·6H2O and Na4SiO4 aqueous solutions with an Al/Si molar ratio of 2.5, addition of HF for a
F/Si molar ratio of 0.1 À 0.2, and 4 days of crystallization at 98°C.

Vol. 1(2), pp. 45-50 
article  
Abstract: Cocoons of the Bombyx mori silkworm are mainly composed of twin tread fibroins with sericin surrounding them. The fibroin fiber is used for the silk fabric industry, while the sericin is removed for preparing soft and shiny silk fibers. Thus, degumming waste solution with sericin from silk cocoon was obtained from silk manufacturer. The sericin powder can be extracted from cocoon waste by boiling it in water and then hydrolyzed by citric acid. We have succeeded in preparation the self-assembly films based on electrostatic interaction between sericin and cationic amphiphile (DDAB). X-ray photoelectron spectroscopy and atomic force microscope results indicate that this film has a lamellar multilayered structure with layers of sericin being separated by lipid bilayers of DDAB. The tensile properties of this sericin/DDAB film correspond with the structure of film.

Abstract: The development of new antibacterial coating (against Escherichia coli and Staphylococcus aureus) with the use of a natural dye (curcumin) and epoxidized soybean oil, according to a photochemistry process has been investigated. Curcumin has been used both as a photosensitizer and an antibacterial agent under visible light illumination. The photoinduced coatings show good adherence properties on an inox substrate and a high thermal stability to 375 [degree]C. Under visible light activation, singlet oxygen (1O2) could be generated from the curcumin derivative-coatings, thus inhibiting by 99% and 95% the growth of Staphylococcus aureus and Escherichia coli, respectively, even after 48 h of incubation.

Abstract: By using a steric approach, it is possible to design templates matching closely with an inorganic framework. Herein, the design, synthesis and successful application of several di(azacrown ether) templates to direct the formation of EMC-1 zeolite (FAU-type) are reported. Following a high throughput experiment design, the synthesis gel composition was optimized to obtain well-crystallized materials. Taking into account their respective crystallization rates, their textural and morphological properties were comparable to their counterparts, typically structured by 15-crown-5 ether. © T.J.

Vol. 199Materials Science and Engineering B: Solid-State Materials for Advanced Technology, pp. 77-86 
article URL 
Abstract: The goal of this work was to study the thermal stabilization of calcium apatites in which the Ca2+ ions were substituted for Sr2+ in increasing concentrations via ionic co-substitutions. Two distinct standard syntheses were proposed for comparative purposes: one using counter-ions that were not easily incorporated into the apatite structure (NH4+/NO3-) and one using counter-ions that can be easily incorporated into the structure (Na+/Cl-). After calcination, only the apatites synthesized in the presence of NH4+/NO3- presented phase transformation. In contrast, the apatites synthesized in the presence of Na+/Cl- formed a solid solution after calcination, with Na+, Ca2+, Sr2+ and Cl- sharing the same apatite lattice. Wavelength dispersive X-ray fluorescence spectroscopy (WDXRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and temperature-programmed desorption (TPD) techniques showed that the counter-ions present during the syntheses that are associated with CO32- play an important role in the thermal stabilization of the apatites. © 2015 Elsevier B.V.

Abstract: Germanene, a 2D honeycomb structure similar to silicene, has been fabricated on Al(111). The 2D germanene layer covers uniformly the substrate with a large coherence over the Al(111) surface atomic plane. It is characterized by a (3 ? 3) superstructure with respect to the substrate lattice, shown by low energy electron diffraction and scanning tunnelling microscopy. First-principles calculations indicate that the Ge atoms accommodate in a very regular atomic configuration with a buckled conformation.

Abstract: The excited-state relaxation dynamics of a D-π-A sulfonium-based alkoxystilbene photoacid generator has been investigated in acetonitrile solution by using femtosecond transient absorption and nanosecond laser flash photolysis experiments. For the first time, the successive reaction steps involved in the photoinduced proton generation of a sulfonium acid generator have been kinetically and spectrally resolved from the early stages (femtosecond time scale) to the final chemical processes (microsecond domain). An overall four-step reaction scheme is established, and two main deactivation pathways limiting the proton generation efficiency are identified and quantified.

Highly spin-polarized carbon-based spinterfaces 2015 Carbon
Vol. 87, pp. 269-274 
article DOI  
Abstract: We deploy topographical and spectroscopic techniques to show that a strongly spin-polarized interface arises between ferromagnetic cobalt and an amorphous carbon layer. Scanning tunneling microscopy and spectroscopy show how a semiconducting carbon film with a low band gap of about 0.4 eV is formed atop the metallic interface. To understand how the cobalt/carbon interface is formed, we used X-ray photoemission spectroscopy to study the hybridization state of carbon. We find that the semiconducting layer consists mainly of sp(2)-bonded carbon atoms with a sp(2)-to-sp(3) ratio between 1.4 and 1.8. The spin-polarized properties of the cobalt/carbon interface are studied by spin-resolved photoemission spectroscopy. We observe interface states close to the Fermi energy that are not exclusive to cobalt. These electronic states reveal a high degree of spin polarization at room temperature. (C) 2015 Elsevier Ltd.

article URL 
Abstract: In aeronautic industries, powder coatings are increasingly used because of environmental considerations. During the deposition of such a coating on a substrate piece, the main objective is to obtain a good coating/substrate adhesion. In this study, the targeted substrate is a Poly-(Ether EtherKetone)-(PEEK) based composite material. Due to the poor surface energy of PEEK, a surface treatment is necessary in order to enhance its adhesion with the coating. In this purpose, atmospheric plasma treatment has been chosen and the influence of plasma parameters has been studied. Four scan speed nozzles and three gases (Air, N2 and Argon) plasma has been tested. The increase of adhesion with increasing wettability, polarity and nanoroughness has been evidenced. A particular study of the type of grafted polar functionalities according to gas nature allowed to better understand the plasma mechanism and the cross-impact of polarity and nanoroughness in adhesion enhancement. © 2015 Elsevier B.V.

Dutournie, P., Said, A., Daou, J., Bikai, J. and Limousy, L. Hydraulic Performance Modifications of a Zeolite Membrane after an Alkaline Treatment: Contribution of Polar and Apolar Surface Tension Components 2015 Advances in Materials Science and Engineering
Vol. ID 524259, pp. 7 pages 
article DOI  
Abstract: Hydraulic permeability measurements are performed on low cut-off Na-mordenite (MOR-type zeolites) membranes after a mild alkaline treatment. A decrease of the hydraulic permeability is systematically observed. Contact angle measurements are carried out (with three polar liquids) on Na-mordenite films seeded onto alumina plates (flat membranes). A decrease of the contact angles is observed after the alkaline treatment for the three liquids. According to the theory of Lifshitz-van der Waals interactions in condensated state, surface modifications are investigated and a variation of the polar component of the material surface tension is observed. After the alkaline treatment, the electron-donor contribution (mainly due to the two remaining lone electron pairs of the oxygen atoms present in the zeolite extra frameworks) decreases and an increase of the electron-receptor contribution is observed and quantified. The contribution of the polar component to the surface tension is attributed to the presence of surface defaults, which increase the surface hydrophilicity. The estimated modifications of the surface interaction energy between the solvent (water) and the Na-mordenite active layer are in good agreement with the decrease of the hydraulic permeability observed after a mild alkaline treatment.

Vol. 26(2), pp. 108 
article DOI  
Abstract: It has been previously shown that osteosarcoma (SaOs-2) cells respond to micropillared surfaces consisting of poly-L-lactic acid with strong deformation of the cell body and nucleus. Until now, cell nucleus deformation of SaOs-2 cells was only studied by exposing them to square shaped micropillars in an isotropic pattern. Herewe report on experiments of the cell nucleus response of such cells to rhombic structures of different topographies generated from a rubbery polymer, namely poly(n-butyacrylate). It is observed that cells orientate themselves perpendicular to the long axis of the rhombi. While their spreading on the surface is not influenced by the opening angle of the structures, rhombic structures with sharper angles induce stronger deformation of the cells and accordingly more elongated nuclei.

Abstract: Abstract The aim of this work was to identify and quantify the chemical and structural modifications occurring during the pyrolysis of Miscanthus x giganteus. Miscanthus was pyrolyzed at slow heating rate (5 K/min) in the temperature range 200-400 °C. The biochars were then characterized by combining Diffuse Reflectance Infrared Fourier Transform spectrometry (DRIFTs) and ultraviolet Raman spectrometry (UV Raman). In addition, the quantification of the functional groups remained on the biochars was conducted by Temperature Programmed Desorption - Mass Spectrometer (TPD-MS) analysis.

Abstract: Abstract In this paper, mesoporous silica based adsorbents were synthesized and evaluated for the desulfurization of flue gas streams. KIT-6 mesoporous silica was impregnated with CuO, CeO2 and CuO-CeO2. The materials were characterized by XRD, N2 adsorption-desorption, SEM, TEM and XPS analysis. The activity of the obtained adsorbents was evaluated at 400 °C with a GHSV (Gas Hourly Space Velocity) of 25,000 h−1 for the removal of SOx from gas streams. The results show that the co-impregnation of copper and cerium on KIT-6 results in a synergistic effect in terms of SO2 removal.

Abstract: Abstract In this paper, SBA-15 mesoporous silica based adsorbents were synthesized for the desulfurization of flue gas streams, by several methods (wet impregnation, incipient wetness impregnation and ion exchange). The influence of the drying and calcination conditions on the porous texture and the dispersion of the active phase (CuO), as well as the efficiency of the adsorbents for SOx trapping, were studied. Depending on the synthesis conditions, copper species are present as large CuO particles (1 μm) and/or as homogeneously dispersed species, undetectable by XRD/TEM. The SOx adsorption efficiency seems to be closely related to the undetected copper species.

Abstract: We present herein a joint phys./physico-chem. study and, more specifically, the first application of Matrix Assisted Laser Desorption Ionization coupled with Time of Flight Mass Spectrometry (MALDI-TOF-MS) to analyze small-sized ZnO quantum dots (QDs) (2.8-3.1 nm diam. range) synthesized by sol-gel chem. and stabilized through an aminosilane coating. A careful investigation of the stability of ZnO QDs was initiated once these dots were dispersed in different media (water, biol. buffer) for a period up to 3 wk. Pos. ion mode mass spectra MALDI-TOF-MS combined with optical spectrometry was used to monitor the stability of ZnO QDs when aging. Such a unique combination of MALDI-TOF-MS and physico-chem. techniques is likely to bring new insights into the structure anal., the stability and consequently the potential toxicity of QDs.

Vol. 5(4), pp. 2861-2868 
article DOI  
Abstract: The synthesis of ordered porous carbons by a green, simple and rapid approach based on light exposure of a solution of carbon precursors and a soft-template in the presence or not of a photosensitizer is demonstrated herein along with their formation mechanism. The influence of the benzophenone amount on the formation of phenolic resin and the carbon structure, morphology and textural properties was systematically studied. The polymerization, self-assembly and carbonization are promoted in the same step by light. The benzophenone accelerates several times the reaction rate modifying mainly the phenolic-resin structure (higher degree of cross-linking and carbonization) via radical formation, as highlighted by Raman spectroscopy. In addition, the increase of benzophenone amount gradually induces the modification of carbon morphology from a worm-like disordered structure to a highly organized hexagonal one while the surface area and pore volume remain unchanged. The C-13 and H-1 solid state and relaxation NMR analysis pointed out that this behavior is triggered by the different micellar structuration of the template in the presence of benzophenone, the phenolic-resin composition involving only carbon precursor derived compounds and not benzophenone.

Vol. 7(22), pp. 10111-10122 
article URL 
Abstract: A novel one-pot laser-assisted approach is reported herein for the synthesis of ordered carbons with embedded cobalt nanoparticles. The process is based on a UV pulsed laser exposure of an ethanolic solution consisting of green carbon precursors, a structure directing agent and a cobalt salt. Very short irradiation times (5 to 30 min) are only required to polymerize and cross-link carbon precursors (i.e. phloroglucinol and glyoxylic acid) independent of a catalyst presence. The influence of three metallic salts (acetate, nitrate and chloride) on the phenolic resin and carbon characteristics (structure, texture and particle size/distribution) was systematically studied. When exposed to UV laser, the metallic salt exhibited a strong influence on the particle size and distribution in the carbon matrix rather than on the textural carbon properties. Using cobalt acetate, very small (3.5 nm) and uniformly dispersed particles were obtained by this simple, fast and green one-pot synthesis approach. An original combined 13C CP-MAS and DP-DEC solid state NMR spectroscopy analysis allowed to determine the structure of phenolic resins as well as the location of the cobalt salt in the resin. Complementarily, the 1H solid-state and relaxation NMR provided unique insights into the rigidity (cross-linking) of the phenolic resin and dispersion of the cobalt salt. The magnetic properties of cobalt nanoparticles were found to be size-dependent: large Co nanoparticles ([similar]50 nm) behave as bulk Co whereas small Co nanoparticles are superparamagnetic.

article URL 
Abstract: Abstract Activated carbon was prepared from olive stones by physical activation using water vapor at 750 °C. Textural, morphology and surface chemistry characterizations were achieved (nitrogen adsorption, SEM, FTIR and TPD-MS). NO2 adsorption was performed for different inlet gas compositions and temperatures. NO2 may adsorb directly on the oxygenated surface groups, and can also be reduced to NO. Therefore, a second NO2 molecule adsorbs on the oxygen left on the carbon surface. TPD performed after NO2 adsorption showed the presence of various surface groups. The adsorption capacity was about 131 mg/g, which is higher than with several activated carbon prepared from classical lignocellulosic biomass. NO2 reduction into NO decreased with increasing the inlet oxygen concentration. In contrast, a slight decrease in the NO2 adsorption capacity was observed with increasing temperature. It seems that the activated carbons prepared from olive stones by steam activation could be used as efficient adsorbents for NO2 removal.

Vol. 59, pp. 7-12 
article DOI  
Abstract: Hydrogenated nitrogen-rich graphitic carbon nitride materialwas successfully synthesized by pyrolysis at 550 °C
of an unusual organic precursor molecule, namely guanidine carbonate. The product was characterized in detail
using X-ray diffraction, chemical analysis, diverse spectroscopy techniques (Fourier transform infrared, X-ray
photoelectron, ultra-violet visible absorption), nitrogen adsorption, and scanning electron microscopy. The results
of characterization clearly confirmed the synthesis of a graphitic carbon nitride material (stacking of tri-striazine
planes) composed of C3.00N4.29H1.59O0.77. In order to understand the mechanism of material formation,
products obtained at different temperatures between 200 and 500 °Cwere systematically investigated. The guanidine
carbonate salt precursor is presented to be a promising alternative source for the elaboration of the g-C3N4
material in relation to the classically used cyanamide, melamine or cyanuric-based molecules. Since it ismore environmentally
friendly and highly soluble in aqueous solvents this new method is definitely strengthening the
possibility of process industrialization

Vol. 119(-), pp. 208-216 
article URL 
Abstract: Abstract The present work was devoted to the photostability of two homopolymers, resulting from the polymerization of acrylate monomers used as components of recording materials. This study was undertaken in conditions simulating solar light. The objective was to identify the key elements specific of the degradation of each polymer. This approach passed through the understanding of the chemical modifications of the polymer matrix and therefore through the elucidation of the mechanism of degradation. Photo-IR experiments and GC-MS analysis were performed to identify the organic volatile compounds stemming from the photo-oxidation of each homopolymers. A new methodology based on the photo-purge-trap-GC-MS was implemented to have a better insight of the elucidation of the pathways of degradation.

Vol. 17, pp. 30240-30247 
article DOI URL 
Abstract: The wedge-shaped amphiphiles bearing sulfonate groups at the tip of the wedge are prone to form ion nano-channels upon exposure to a humid atmosphere. During swelling, water molecules preferentially accumulate in polar regions of the system resulting in the formation of a lyotropic phase. In this work, the details of the structure formation processes occurring upon swelling in water vapour, including determination of the size and topology of the ion nano-channels, are explored. The electron density profiles across the channel are obtained from the fits of the X-ray scattering data with two- and three-phase structural models the applicability of which is critically analysed. The results show that the ion channel size correlates not only with water uptake but also with the molecular architecture such as the structure of the rigid molecular fragment bearing a polar group. These findings can help optimising the ion transport for development of ion-selective membranes.

Guizani, C., Escudero Sanz, F., Jeguirim, M., Gadiou, R. and Salvador, S. The effects of textural modifications on beech wood-char gasification rate under alternate atmospheres of CO2 and H2O 2015 Fuel Processing Technology
Vol. -(-), pp. - 
article URL 
Abstract: Abstract Despite the huge literature on biomass char gasification with CO2 or H2O, ambiguity still hovers over the issue of char gasification in complex atmospheres. Gas alternation gasification experiments, in which the reacting gas is changed during the reaction, were performed with CO2/H2O at 900 °C for small (200 μm) and large (13 mm) Low Heating Rate (LHR) beech wood char particles to assess the potential influences that CO2 and H2O can have on each other during the char gasification reaction. The results showed no influence of a first gasification atmosphere on the char reactivity under the second one. The char reactivity to a specific gas at a certain conversion level was the same as if the gasification reaction was operated from the beginning with the same atmosphere composition. The purpose of this paper is to bring understanding keys to this lack of influence of previous gasification conditions on the char reactivity. Characterization of the chars throughout the conversion by measuring the total surface area and the active surface area was first performed. Then a transport limitation analysis based on the Thiele modulus was considered. It was concluded that the two gasses develop different porosities in the char, however, the Thiele modeling results and active surface area analysis indicate respectively that gasses diffuse preferentially in large macro-pores and that the concentration of active sites evolves similarly during both gasification reactions. This similarity in the diffusion mechanism as well as in the evolution of the concentration of active sites could be a plausible explanation for the only-dependent conversion reactivity observed in the gas alternation gasification experiments.

Vol. 15(1), pp. 442-449 
article DOI  
Abstract: We present an experimental investigation of the mechanical stability of silica nanoparticle-based coatings as a function of the size of the nanoparticles. The coatings are built following a layer-by-layer procedure, alternating positive and negative surface charges. The mechanical stability of the multilayers is studied in water, on the basis of an ultrasonic cavitation test. The resistance of the coating to cavitation is found to remarkably increase with decreasing the size of the nanoparticles, indicating an increase of the cohesive energy density. The relative contribution of van der Waals and electrical double-layer interactions to the stability of the multilayer is discussed toward their size dependence.

Vol. -(-), pp. 14 pages 
article DOI URL 
Abstract:
Non-vulcanized styrene-butadiene rubber thin films were exposed to Radio-Frequency low-pressure air plasma. Two different configurations corresponding to direct and downstream RF plasmas were compared. Optical emission spectroscopy provided information about plasma composition and temperature. The plasma treated SBR surfaces were characterized by contact angles and XPS spectroscopy. Two different phenomenological mechanisms are proposed to describe the observed differences according to the plasma configuration used and account for the impact of the activated gas phase on the structure of plasma-treated non-vulcanized SBR surface..

Abstract: Surface modification studies of non-vulcanized BR elastomers (butadiene
rubber) by low-pressure air plasma treatment and the effect on ageing and adhesion performances
are presented in this paper. In particular, the influence of discharge power and
distance from the glow discharge, and impact of antioxidant molecules in the BR formulation
were examined. To characterize the changes to the BR surface, XPS spectroscopy,
contact angle measurements, AFM nanoindentation experiments and tack
measurements were utilized. Oxidation and crosslinking were the main mechanisms
observed on the polymer chains regardless of the plasma conditions used. Beyond a certain
threshold of plasma energy (in our case, discharge power of *60 W and exposure time of
*30 s), a steady state was reached irrespective of the distance from the glow discharge.
The presence of antioxidant molecules considerably reduced crosslinking phenomena
while maintaining oxidation processes on polymer chains and increasing the nitrogen
content in the near surface region. The mechanisms responsible for these differences have
been identified. Interestingly, the COOH/C=O ratio changed according to the balance
between oxidation and crosslinking. The hydrophobic recovery rate was mainly driven by
temperature-dependent dynamics and varied according to the degree of crosslinking in the
surface region. It was found to be lower in air atmosphere in the presence of antioxidant
molecules. Finally, the presence of antioxidant molecules in the BR formulation allowed
the adhesion performances after plasma exposure to significantly increase.

Vol. 148(-), pp. 426-441 
article URL 
Abstract: Abstract Sorption/desorption kinetics for selected radionuclides (99Tc(VII), 232Th(IV), 233U(VI), 237Np(V), 242Pu and 243Am(III)) under Grimsel (Switzerland) ground water conditions (pH 9.7 and ionic strength of ∼1 mM) in the presence of synthetic Zn or Ni containing montmorillonite nanoparticles and granodiorite fracture filling material (FFM) from Grimsel were examined in batch studies. The structurally bound Zn or Ni in the octahedral sheet of the synthetic colloids rendered them suitable as colloid markers. Only a weak interaction of the montmorillonite colloids with the fracture filling material occurs over the experimental duration of 10,000 h (∼13 months). The tri- and tetravalent radionuclides are initially strongly associated with nanoparticles in contrast to 99Tc(VII), 233U(VI) and 237Np(V) which showed no sorption to the montmorillonite colloids. Radionuclide desorption of the nanoparticles followed by sorption to the fracture filling material is observed for 232Th(IV), 242Pu and 243Am(III). Based on the conceptual model that the driving force for the kinetically controlled radionuclide desorption from nanoparticles and subsequent association to the FFM is the excess in surface area offered by the FFM, the observed desorption kinetics are related to the colloid/FFM surface area ratio. The observed decrease in concentration of the redox sensitive elements 99Tc(VII), 233U(VI) and 237Np(V) may be explained by reduction to lower oxidation states in line with Eh-pH conditions prevailing in the experiments and thermodynamic considerations leading to (i) precipitation of a sparingly soluble phase, (ii) sorption to the fracture filling material, (iii) possible formation of eigencolloids and/or (iv) sorption to the montmorillonite colloids. Subsequent to the sorption/desorption kinetics study, an additional experiment was conducted investigating the potential remobilization of radionuclides/colloids attached to the FFM used in the sorption/desorption kinetic experiments by contacting this FFM with pure Grimsel groundwater for 7 days. A positive correlation of 242Pu, 232Th(IV) and 237Np was observed with the Zn and Ni concentrations in the desorption experiments indicating a remobilization of sorbed montmorillonite colloids. The results of the study in hand highlight (i) the novel use of structural labeled colloids to decrease the uncertainties in the determination of nanoparticle attachment providing more confidence in the derived radionuclide desorption rates. Moreover, the data illustrate (ii) the importance of radionuclide colloid desorption to be considered in the analysis and application of colloid facilitated transport both in laboratory or in-situ experiments and numerical model simulations and (iii) a possible remobilization of sorbed colloids and associated radionuclides by desorption from the matrix material (FFM) under non-equilibrium conditions.

Vol. 47(4), pp. 523-528 
article DOI  
Abstract: The grafting of trialkoxysilane molecules should also give rise to the formation of a siloxane network at the substrate's surface when trialkoxysilanes are used. Other candidates that might be able to act as adhesion promoters at metallic surfaces are dimethylalkoxysilanes. The advantage of dimethylalkoxysilanes is that only one silanol group is produced during the hydrolysis step, leading to the formation of a grafted monolayer onto the steel. Moreover, the chemical grafting of stainless steel, which exhibits a low surface reactivity, is of great interest for industrial applications such as adhesive bonding or coatings. The objective of this work was to chemically graft dimethylalkoxysilanes onto AISI 316L stainless steel and to analyze the grafted layer by X-ray photoelectron spectroscopy (XPS). Investigation of the hydrolysis of these molecules in aqueous solutions was also performed by proton nuclear magnetic resonance spectroscopy (H-1 NMR). The grafting of 3-(ethoxydimethylsilyl)propylamine (APDES) and 3-glycidoxypropyldimethylethoxysilane (GPDES) was achieved onto stainless steel after a controlled hydrolysis reaction. A pH inferior or equal to 5 was necessary to obtain a sufficient hydrolysis of silanes. XPS results have evidenced the grafting of the silanes onto stainless steel. The signal of the Si 2p peak clearly showed the formation of a covalent bond between APDES and the stainless steel surface through the O atoms giving rise to a uniform layer of adsorbed molecules. Moreover, this grafted layer is strongly stable as no removal of the alkoxysilane was observed after immersion in hot water which is very critical for these molecules.

Vol. 3(22), pp. 11960-11969 
article URL 
Abstract: Confined and unconfined SnO2 nanoparticles in the pores of mesoporous carbon were prepared and tested as anode materials vs. Na. Both composites present small crystalline SnO2 particles ([similar]3 nm) but different location and dispersion in the carbon matrix. When the particles are homogeneously distributed and confined in the carbon pores, an initial reversible capacity of 780 mA h g-1 is achieved with unprecedented capacity retention of 80 and 54% after 100 and 4000 cycles, respectively, at a high current rate (50 C, 1800 mA g-1). Unexpectedly, over two current rate variation cycles from 1 C to 500 C, the composite recovers 81% and 97%, respectively after returning from the 500 C to the 1 C rate. To our knowledge, no other material with such a long cycling life and superior performance in terms of capacity and rate capability has been reported so far for sodium ion batteries. HRTEM, XRD, N2 adsorption, XPS and galvanostatic cycling results suggest that confined SnO2 particles undergo an enhanced sodium alloying/dealloying process due to their special confinement inside the pores, which increases their conductivity, facilitates the diffusion of Na+ ions and buffers the large volumetric changes during charge/discharge. These high performances cannot be delivered when SnO2 is not confined and not well dispersed in the carbon pores. This work demonstrates that nano-confinement of anode species in carbon is a valuable concept affording the modification of the fundamental properties of guest species along with their electrochemical performances leading to highly stable and performing materials with a long life for Na-ion batteries.

Abstract: LiBH4?Mg2NiH4 reactive hydride composites have been nanoconfined into two types of mesoporous carbons: a templated carbon with ordered small pores of ?4 nm and a carbon aerogel with pores size of ?30 nm. In situ synchrotron X-ray diffraction has revealed the formation of the MgNi2.5B2 compound during dehydrogenation at 300 °C and 5 bar of H2 pressure. The hydrogen desorption from nanoconfined LiBH4?Mg2NiH4 shows a single-step reaction at around 300 °C, as observed by mass spectroscopy coupled with thermogravimetric analysis. A synergistic effect is suggested, which facilitates lower hydrogen release than previously reported nanoconfined systems. Effective nanoconfinement provides faster kinetics of hydrogen release.

Vol. 5(68), pp. 55340-55347 
article URL 
Abstract: Novel sulfonium-based D-[small pi]-A photoacid generators (PAGs) with a benzene oligomer (from one to four) as a [small pi]-conjugated system that are highly photosensitive in the near-ultraviolet region (365 nm) were prepared. The maximum absorption and molar extinction coefficients of the PAGs redshifted and enhanced with the increasing length of the conjugated systems. The quantum yields of PAGs were high (three of them were over 0.6) and improved by adjusting the number of the phenyl rings. The quantum chemical calculation results proved that the molecular configuration and nature of the frontier orbitals are crucial factors which affect PAG performance. Photopolymerization kinetic results demonstrated that these sulfonium-based PAGs were highly efficient cationic photoinitiators, and the i-line sensitivities were evaluated based on the photolithographic performance of the PAG-containing SU-8 resins. In addition, the two-photon absorption cross sections ([small delta]700 nm > 400 GM) matched the requirements needed in the 3D fabrication of polymer microstructures.

Abstract: The energetic performances of "ZIF-8-water" systems were evaluated using intrusion-extrusion of water under high pressure. Depending on the shape (spherical, cubic or rhombic dodecahedron) as well as the crystallite size (nanometric or micrometric scale), the energetic behaviour of the "ZIF-8-water" system can be modified.

Abstract: Abstract The use of organic wastes as new renewable energy sources is becoming necessary to achieve the growing energy demand in Tunisia. In this work, the pyrolysis of abundant waste fish fats provided by a canned Tuna factory was examined in a laboratory fixed-bed reactor. The main objective was to analyze the properties and the composition of the produced bio-oil using in order to implement the suitable valorization strategy. Therefore, high heating value, viscosity, density, flash point, acidity index, moisture content and ash content measurements as well as FTIR and GCMS analyses were carried out to characterize the pyrolytic oil obtained during waste fish pyrolysis at 500 °C.

Kulaga, E., Ploux, L. and Roucoules, V. Effect of ageing and sterilization on plasma multilayer system 2015 Polymer Degradation and Stability
Vol. 116(0), pp. 1-13 
article URL 
Abstract: Abstract Single and coupled effects of sterilization (autoclaving and electron beam) and ageing of plasma polymer multilayer coating on polypropylene mesh are studied. The multilayer system consists in silver nanoparticles entrapped between two maleic anhydride plasma polymer layers and acts as a mechano-sensitive antibacterial reservoir. Tensile strength generates cracks within the plasma polymer overlayer which might be used as diffusive channels for Ag+ species. Changes in surface and bulk properties are followed by SEM, TEM, XPS and antibacterial assays. Whilst autoclave treatment influences surface structure unfavorably, electron beam irradiation with dose of 25 kGy does not induce surface physical or topographical changes. However, electron beam sterilization induces changes in chemistry of the surface causing a decrease in O/C elemental concentration ratio. The surface shows better antibacterial efficiency towards planktonic bacteria after electron beam sterilization and more surprisingly, the combination of electron beam sterilization and ageing has beneficial effect on final properties of the material under stretching.

Vol. 153, pp. 431-436 
article  
Abstract: The main purpose of this present work is to study the combustion characteristics of a domestic boiler (12 kW) when fired with biofuels prepared by blending an industrial by-product (pine sawdust, PS) and an agro-industrial by-product (Olive Mill Solid Waste, OMSW). The boiler and combustion efficiencies as well as gaseous emissions were determined and compared to EU normalization standards (EN 303-5). It was found that the main exhaust gases (CO, CO2 CxHy and NOx) are emitted in acceptable concentrations comparing to other biofuels in the literature. The analysis of bottom ash compositions shows the presence of three oxides, namely CaO, K2O and SiO2 as well as a significant amount of unburned carbon. Hence, the boiler control through the primary and secondary air injections should be adapted to the different pellets properties. Additionally, both combustion efficiency and boiler efficiency results are encouraging for considerations of prepared agropellets as alternatives to woody biofuels. (C) 2015 Elsevier Ltd.

Abstract: A novel straightforward approach has been proposed to generate in situ, under light activation and in aerated media, visible-light absorbing and well-defined titanium-based nanoparticles (NPs) in solution and in an epoxide matrix using titanium derivative complexes/iodonium salt photoinitiating systems. The nature of the solvent and oxygen plays a decisive role, and two mechanisms involved in these syntheses are operative, i.e. a photofragmentation/addition process (in toluene and isopropanol) and a photoinduced sol-gel reaction (in isopropanol).

Abstract: The very recent developments of novel photoinitiators and photoinitiating systems in photoinduced radical and cationic polymerization reactions are reviewed. The use of mild irradiation conditions in the blue-to-red wavelength range (household halogen lamps, LEDs, fluorescent bulbs, sunlight; reactions under air) is particularly outlined. New opportunities in applications requiring such experimental conditions in sunlight curing, photoredox initiated polymerizations or in situ incorporation of nanoparticles in a photopolymerizable matrix are described. © The Royal Society of Chemistry 2015.

Abstract: Herein, we report theoretical evidence of the geometric changes occurring upon complexation, for a series of octupolar bipyrimidine-based ligands incorporating the NPh2 terminal donor group. It is shown that ligands 1 and 2 (4,4',6,6'-tetrakis(N,N-diphenylaminostyryl)-[2,2']bipyrimidine and 4,4',6,6'-tetrakis((N,N-diphenyl)-9,9'-dioctyl-9H-fluorene-2-amine)-2,2'-bipyrimidine) exhibit a nonplanar geometry with a torsion angle between both pyrimidine moieties of similar to 25 degrees and 50 degrees respectively. 1a (complex of 1) becomes planar upon addition of ZnCl2 to the bipyrimidine moiety whereas 2a remains distorted. Furthermore, an assignment of the absorption bands for all compounds is presented.

Vol. 87(2), pp. 843-847 
article DOI  
Abstract: Solid state NMR methods are required to analyze biomass as a function of its chemical or biological treatment for biofuels, chemicals, or biochar production. The native polymers network in lignocellulosic biomass and other solid materials, such as coal, coke, or biochar, can hardly be analyzed by liquid state NMR due to their poor swelling ability without chemical modification. A H-1-C-13 two-dimensional heteronuclear correlation (HETCOR) experiment with frequency-switched Lee-Goldburg (FSLG) irradiation is performed on a high field spectrometer (750 MHz). This method leads to previously unattained resolution for biomass and biochar and offers a unique ability to reveal their chemical composition. The formation of aromatic moieties from carbohydrates and lignin thermal conversion is clearly distinguished. This method can be applied to all other carbonaceous materials.

Abstract: Two heteroleptic iridium complexes were synthesized and their photophysical properties studied. The two complexes vary by their ancillary ligand that is respectively acetylacetone (acac) or dibenzoylmethane (dbm). Interestingly, only the acac-based complex proved to be highly emissive and electroluminescent devices were only fabricated with this complex. In order to determine the emissive properties of this new complex, comparison with complexes previously reported in the literature was established. (C) 2014 Elsevier B.V. All rights reserved.

Abstract: Abstract Three heteroleptic iridium(III) complexes comprising 1-methyl-3-propyl-5-(2,4,5-trifluorophenyl)-1H-1,2,4-triazole (tfpt) as the cyclometalated ligand and varying by their ancillary ligands were examined as triplet emitters for Phosphorescent OLEDs. Interestingly, major differences in device performances were obtained with these three isostructural complexes comprising dibenzoylmethane (dbm), acetylacetone (acac) or pyridine-2-carboxylic acid (pic) as the ancillary ligands. Best OLEDs were fabricated with the dibenzoylmethane-based iridium(III) complex. On the opposite, the picolinate and the acetylacetonate-based complexes gave moderate performances. To complement this work, theoretical calculations were carried out on the three complexes. The newly synthesized complex i.e., Ir(tfpt)(pic) was also characterized by UV-vis absorption and luminescence spectroscopy as well as cyclic voltammetry.

Vol. -(-), pp. 16 pages 
article DOI URL 
Abstract: Abstract Soybean-furfural (SoyFu) adhesives were synthesized through cross-linking soybean flour with furfural under alkaline conditions and the performance of the resulting bio-adhesives was evaluated by manufacturing plywood panels. A total of 30 different bio-adhesive formulations were studied (5 levels of furfural content and 6 levels of sodium hydroxide or pH). Thirty 2-ply plywood panels prepared with these adhesives were pressed at 140 °C for 4 minutes. Shear tests were performed on the panels according to ASTM D2339-1998 (2004). The statistical analysis indicated that an interaction existed between furfural (crosslinker) and sodium hydroxide (pH) levels. The best quality panels were produced using adhesives containing high levels of sodium hydroxide (12, 20 and 28 g /100 g soy flour) and high levels of furfural (50 and 100 g /100 g soy flour). 13C nuclear magnetic resonance analyses were also performed on a selected formulation. The spectra analysis, however, did not prove that furfural was involved in covalent or ionic bonds with soybean flour.

Vol. 62(2), pp. 157-167 
article DOI  
Abstract: In the first part of this paper, a model describing photopolymer materials, which incorporates both the physical electromagnetic and photochemical effects taking place, was developed. This model is now validated by applying it to fit experimental data for two different types of photopolymer materials. The first photopolymer material, acrylamide/polyvinyl alcohol, is studied when four photosensitizers are used, i.e. Erythrosine B, Eosin Y, Phloxine B and Rose Bengal. The second type of photopolymer material involves phenanthrenequinone in a polymethylmethacrylate matrix. Using our model, the values of physical parameters, are extracted by numerical fitting experimentally obtained normalized transmittance growth curves. Experimental data sets for different exposure intensities, dye concentrations, and exposure geometries are studied. The advantages of our approach are demonstrated and it is shown that the parameters proposed by us to quantify the absorptive behavior in our model are both physical and can be estimated.

Abstract: Abstract Spent coffee grounds (SCG), a processing by-product from the soluble coffee industry, was evaluated as a potential feedstock for preparing compressed logs for energy production. Hence, a blend of SCG/wood chips was transformed into densified logs using an industrial press. Chemical properties such as calorific value, ash content and elemental analysis were obtained. Combustion tests were carried out with a five-star-labeled stove in a French industrial research and development laboratory. Three different configurations were tested: a densified log containing 20 wt% of SCG blended with pine wood chips, another containing a mixture 50/50 wt% of SCG/pine wood chips and a classical beech log. This study is the first one that focuses on the potential of compressed logs as a new biocombustible for wood stoves. The obtained results show that the combustion of logs containing SCG leads to better yield of combustion. Nevertheless, CO and particle emissions increase when increasing the rate of SCG although the exhaust gas emissions and combustion yields always lead to the “five-star Flamme Verte” label achievement. Such attainment is essential to sell these densified biofuel logs in the French market. Results indicate that the blended densified logs are combusted rapidly leading to higher stove efficiency and therefore good heat recuperation from the stove walls. On the contrary, the addition of SCG leads to lower CO2 concentrations (7.7% and 9.05% for 20 wt% and 10 wt% of SCG, respectively). This behavior indicates that the combustion of compressed logs is not suitable for the stove design and may lead to an uncomfortable heating. One should be reminded that the evaluated stove was designed for the combustion of conventional wood logs (with respect to the NF Bois de Chauffage standard). This means that the results obtained during this study with the different densified fuel logs could be improved after an adjustment of the stove conception.

Abstract: Deep-UV (DUV) laser was used to directly write indium-gallium-zinc-oxide (IGZO) precursor solution and form micro and nanoscale patterns. The directional DUV laser beam avoids the substrate heating and suppresses the diffraction effect. A IGZO precursor solution was also developed to fulfill the requirements for direct photopatterning and for achieving semi-conducting properties with thermal annealing at moderate temperature. The DUV-induced crosslinking of the starting material allows direct write of semi-conducting channels in thin-film transistors but also it improves the field-effect mobility and surface roughness. Material analysis has been carried out by XPS, FTIR, spectroscopic ellipsometry and AFM and the effect of DUV on the final material structure is discussed. The DUV irradiation step results in photolysis and a partial condensation of the inorganic network that freezes the sol-gel layer in a homogeneous distribution, lowering possibilities of thermally induced reorganization at the atomic scale. Laser irradiation allows high-resolution photopatterning and high-enough field-effect mobility, which enables the easy fabrication of oxide nanowires for applications in solar cell, display, flexible electronics, and biomedical sensors.

Vol. 16(3), pp. 683-694 
article DOI URL 
Abstract: A straightforward method for immobilizing in situ generated silver nanoparticles on the surface of a photoactivable isosorbide-derived monomer is developed with the objective to design a functional material having antibacterial properties. The photoinduced thiol–ene mechanism involved in these syntheses is described by the electron spin resonance/spin trapping technique. The resulting materials with or without silver nanoparticles (Ag NPs) were used as films or as coatings on glass substrate. The surface of the synthesized materials was characterized by X-ray photoelectron spectroscopy and scanning electron microscopy, and their thermal and mechanical properties were evaluated by dynamic-mechanical thermal tests, differential scanning calorimetry, thermogravimetric analyses, along with pencil hardness, nanoindentation, and scratch resistance tests. The photoinduced formation of Ag NPs is also confirmed by UV spectrophotometry. Finally, a primary investigation demonstrates the antibacterial properties of the isosorbide-derived material against Staphylococcus aureus and Escherichia coli, as well as its cytocompatibility toward NIH 3T3 fibroblastic cells.

Abstract: Using neutron scattering and Monte Carlo simulation, we investigate the distribution of cations in Na58Y faujasite upon (de)hydration. We introduce a new method for the assignment of cations to specific sites in molecular simulations from their local environment. This allows us to bypass the need of the coordinates of crystallographic sites, which vary as water adsorption induces changes in the zeolite framework structure. Although the agreement between experiments and simulation is excellent at high temperature, some differences are observed below 150°C. We show that these differences are due to the presence of water and that temperature itself as well as adsorption-induced deformation of the framework play a less important role. We demonstrate the migration of sodium to sites III upon water adsorption, not observed for other Si:Al ratios. © 2015 Taylor & Francis.

Vol. 84(0), pp. 567-583 
article URL 
Abstract: Abstract The fluorination of porous carbonaceous materials was systematically investigated employing different fluorinating agents (molecular F2 and atomic F released by XeF2 decomposition) and conditions (static and dynamic). Two ordered porous carbonaceous materials, that is, mesoporous silica-templated carbon (STC) and microporous zeolite-templated carbon (ZTC), were synthesized along with a microporous commercial carbonaceous material (CPC) for comparison purposes. Besides the different textural features (specific surface area and pore size), the materials present distinct surface chemistries in terms of functional group types and quantity. The influence of material characteristics on the formed fluorinated carbonaceous materials was investigated by several analysis techniques. Thus, the nature, strength, and thermal stability of the C-F bonds was assessed by 13C and 19F nuclear magnetic resonance, Fourier transform infrared spectroscopy, and temperature-programmed desorption coupled with mass spectrometry. The modification of porous texture and organization was carried out by nitrogen adsorption, small-angle X-ray scattering, and transmission electron microscopy. Based on these techniques, the following classifications could be established according to the carbon reactivity under a fluorine atmosphere and employing the fluorination method: STC &gt; ZTC ≫ CPC and F2 static &gt; F2 dynamic &gt; XeF2. The reactivity of the materials is driven by their rich surface chemistry (STC) and high surface area (ZTC).

Abstract: Ensembles of freeze-dried self-rolled polymer micro-scrolls are explored as template media for producing carbon-iron based composites with fibrous morphology. Polymer fibres impregnated with furfuryl alcohol and loaded with Fe2O3 particles, were thermally treated under inert atmosphere at 700 °C and subsequently analysed by scanning and transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, and nitrogen adsorption. The resulting material has a micro-fibrous morphology and is basically composed of metallic Fe0 and FeO particles, i.e., more than 98 wt% of the carbon/iron-based composite mass. These particles are held together by amorphous porous carbon foam obtained by in-situ carbonization of the polymer/Fe2O3 composite with evacuation of carbon from the system via COx gases released by carbo-reduction of Fe2O3. The material has significant activity in the reaction of catalytic decomposition of hydrogen peroxide in water solutions.

Abstract: Four novel onium salts (onium-polyoxometalate) have been synthesized and characterized. They contain a diphenyliodonium or a thianthrenium (TH) moiety and a polyoxomolybdate or a polyoxotungstate as new counter anions. Outstandingly, these counter anions are photochemically active and can sensitize the decomposition of the iodonium or TH moiety through an intramolecular electron transfer. The phenyl radicals generated upon UV light irradiation (Xe-Hg lamp) are very efficient to initiate the radical polymerization of acrylates. Cations are also generated for the cationic polymerization of epoxides. Remarkably, these novel iodonium and TH salts are characterized by a higher reactivity compared with that of the diphenyliodonium hexafluorophosphate and the commercial TH salt, respectively. Interpenetrating polymer networks can also be obtained under air through a concomitant cationic/radical photopolymerization of an epoxy/acrylate blend (monomer conversions > 65%). The photochemical mechanisms are studied by steady-state photolysis, cyclic voltammetry, and electron spin resonance techniques. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Abstract: Two iodonium salts based on a coumarin chromophore are investigated for polymerization upon light emitting diode irradiations (LEDs). They work as one-component photoinitiators. They initiate the cationic polymerization of epoxides (under air) and vinylethers (laminate) upon exposure to violet LEDs (385 and 405 nm). Excellent polymerization profiles are recorded. Their efficiency is quite similar to that of a ferrocenium salt. Interpenetrating polymer networks can also be obtained through a concomitant cationic/radical photopolymerization of an epoxy/acrylate blend monomer. The light absorption properties of these new salts as well as the involved photochemical mechanisms are investigated for the first time through electron spin resonance, laser flash photolysis, steady state photolysis experiments. Molecular orbital calculations are also used to shed some light on the initiation mechanisms. (c) 2015 Wiley Periodicals, Inc.

Vol. 40(6), pp. 2698-2709 
article DOI  
Abstract: Sodium montmorillonite (Na-Mt) was synthesized with the aim to investigate the adsorption and diffusion of hydrogen gas in a model smectite at high pressures (up to 90 bar) and non-cryogenic temperature (363 K). Na-Mt samples were synthesized from hydrogels in mild conditions (493 K and autogenous pressure). Two further Na-Mt samples with different levels of structural iron were prepared to investigate the effect of iron on the textural and hydrogen adsorption properties. Structural and elemental analyses confirmed that well crystalline smectite samples were obtained according to the nominal chemical formulae. Nitrogen adsorption-desorption isotherms revealed that the synthesized materials have specific areas in the range 90-120 m(2)/g and are mainly mesoporous. High pressure volumetric measurements showed that hydrogen absorption at 363 K saturated between 40 and 60 bar, reaching 0.2 +/- 0.02 wt% (i.e. similar to 1.0 mmol/g) at the plateau. Quasielastic neutron scattering revealed ' that hydrogen diffuses inside the clay porous network according to the Fick's law (continuous diffusion), while jump diffusion cannot be excluded at distances lower than 6.3 angstrom, i.e. less than the one between two Na+ exchangeable ions. The hydrogen self-diffusion coefficients in the temperature range 25-300 K were determined to fall in the interval 0.1-1.0 10(-7) m(2) s(-1). The results are compared with H-2(g) adsorption and diffusion in other systems. Copyright (C) 2014, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.

Abstract: The camphorquinone (CQ)/amine and CQ/diphenyl (2,4,6-trimethylbenzoyl)-phosphine oxide (TPO)/amine photoinitiating systems (PISs) are largely used in the area of dental resins, but the role of the light source in connection with the excited state processes has not been deeply investigated so far. Here, a state-of-the-art analysis on the photochemistry of these PISs is provided. Novel experiments using electron spin resonance spin trapping, cyclic voltammetry, photolysis as well as the recording of film polymerization profiles (by real time Fourier transform infrared (FTIR) measurements) of a trifunctional low molecular weight acrylate and a more viscous bisphenol A-glycidyl methacrylate/triethyleneglycol dimethacrylate blend under well-defined irradiation conditions (dental light-emitting diode (LED) and monochromatic laser diode; this has not been done before) are carried out. Although a noticeable improvement under a polychromatic Xe lamp is clearly obtained in the literature when using CQ/TPO/amine compared to CQ/amine, the polymerization profiles of the representative (meth)acrylate monomers are only slightly better under a dental blue LED irradiation (band spectrum centred at 477 nm) and not affected under a laser diode at 473 nm. This work allows a complete and final description of the overall initiation mechanisms in these PISs.

Vol. 6(5), pp. 754-763 
article DOI  
Abstract: The combination of thermally-and photochemically-induced polymerization using light sensitive alkoxy-amines was investigated. The thermally driven polymerizations were performed via the cleavage of the alkoxyamine functionality, whereas the photochemically-induced polymerizations were carried out either by nitroxide mediated photo-polymerization (NMP2) or by a classical type II mechanism, depending on the structure of the light-sensitive alkoxyamine employed. Once the potential of the various structures as initiators of thermally-and photo-induced polymerizations was established, their use in combination for block copolymer syntheses was investigated. With each alkoxyamine investigated, block copolymers were successfully obtained and the system was applied to the post-modification of polymer coatings for application in patterning and photografting.

Vol. 17(1), pp. UNSP 46 
article DOI  
Abstract: Plasmonic silver film was directly generated on a variety of substrates through a facile and environmentally friendly method, which involves a UV-photoreduction process without any reducing or stabilizing agent and requiring no thermal step. Top-coated films of unprotected silver nanoparticles (3-11 nm) were generated from hydroalcoholic AgNO3 solution and directly on glass substrates or food packaging plastic wraps, low density polyethylene film, and polyvinyl chloride. The natural antibacterial activity of the material was evaluated. The correlation between silver migration and antimicrobial activity of silver-functionalized substrates against pure strains of gram-negative bacteria (Escherichia coli) and gram-positive bacteria (Staphylococcus aureus) was demonstrated. By way of illustration, food plastic wraps top-coated in this way exhibited a high antibacterial activity. The metal nanoparticle film obtained in this way was characterized and the influence of several parameters (fluence, exposure, silver nitrate concentration, and nature of the free radicals generator) on their formation was studied. Moreover, by shaping the actinic beam with an appropriate device, it is very easy to pattern the brown yellow silver nanofilm or to print messages in plain text.

Vol. 119(17), pp. 9334-9341 
article  
Abstract: The conformations and the self-assembly process of tetrathiafulvalene (TTF) derivatives functionalized by lateral alkylthio chains deposited on graphene/SiC(0001) in ultrahigh vacuum (UHV) and at the solid-liquid interface are studied by scanning tunneling microscopy (STM). The study in UHV evidences a "molecular fastener" effect induced by the increase of van der Waals interactions between the alkylthio side chains which forces the major part of the molecules to self-organize in pi-pi stacked edge-on conformation. The study at the solid-liquid interface reveals a drastically different behavior with molecules lying flat on the surface as the solvent is involved in the stabilization of the molecular layer. This work raises a burning issue concerning the choice of the deposition method for graphene functionalization with such molecules.

Abstract: Abstract We study theoretically the conditions required for the appearance of a superradiance transition in graphene. The electron properties of graphene are described in the single p z -orbital tight-binding approximation, corresponding to the two interacting sub-lattices. The corresponding model is reduced to the effective two-level pseudo-spin 1/2 system. For each sub-lattice we introduce the electron transfer rate of escape into a continuum. We demonstrate that, under some conditions, the superradiance occurs, and it corresponds to the maximal quantum coherent escape to the continuum.

article URL 
Abstract: Controlled/living atom transfer radical polymerization of methacrylates and acrylates initiated by ethyl [small alpha]-bromophenylacetate (EBPA) as the initiator in the presence of low loadings (1.25 mol% vs. initiator) of a dinuclear gold(i) complex based photocatalyst [Au2([small mu ]-dppm)2]Cl2 has been accomplished in solution and in laminate under UVA and visible-light photoreductive conditions. In solution, the linear increase of molecular weights with methyl methacrylate (MMA) conversion and the low dispersity are consistent with a controlled/living process. In a film, trimethylolpropane triacrylate (TMPTA) was polymerized and the ethyl [small alpha]-bromophenylacetate (EBPA)/[Au2([small mu ]-dppm)2]Cl2 system resulted in a faster rate of polymerization compared to EBPA/Ir(ppy)3. Chain extensions of polymers were successfully conducted leading to block copolymers, which also confirms the living character of this new system. Photophysical experiments support a conventional photoredox-catalyzed ATRP mechanism. Finally, this approach utilizes a gold catalyst featuring better solubility and lower cost than the well-known Ir(ppy)3 complex.

Ouachtak, H., Ait Akbour, R., Douch, J., Jada, A. and Hamdani, M. Removal from Water and Adsorption onto Natural Quartz Sand of Hydroquinone 2015 Journal of Encapsulation and Adsorption Sciences
Vol. 5, pp. 131-143 
article DOI  
Abstract: Hydroquinone (HQ) is the most important hydroxy aromatic compound which is produced on a
large scale. Understanding its fate in the environment is therefore of primary importance to prevent
its migration in the soil and/or the contamination of the aquatic ecosystems. Here we present
a column based method to investigate the physicochemical processes controlling the removal
from the aqueous phase and the adsorption onto natural quartz sand (NQS), of organic pollutant
such as HQ molecules. We will focus on the interactions that occur between the organic pollutant
and the NQS substrate. Thus, column reactors filled with NQS were used to investigate the influence
of physicochemical parameters such as the ionic strength, the pH, the flow rate, and the nature
of the electrolyte cation, on the HQ adsorption from water onto NQS substrate. The data indicate
that, when divalent instead of monovalent cations, are present in the effluent water injection
phase, and/or when the ionic strength of the effluent increases, the adsorbed HQ amount decreases.
Similar decrease of the adsorbed HQ amount was also observed, at constant ionic strength, by
increasing either, the pH from 3 to 9, the flow rate Q from 1 to 3 ml∙mn−1, or by decreasing the HQ
initial concentration, C0 from 30 to 6 mg∙L−1. Further, large amount of the organic pollutant (up to
93 wt% of HQ molecules) was removed from the effluent water phase by using NQS column. The
overall data seem to indicate that the adsorption of HQ molecules on the NQS surface is mainly
controlled by electrostatic interaction forces occurring between the organic molecule polar
groups and the inorganic matrix silanol groups.

Vol. 86(0), pp. 174-187 
article URL 
Abstract: Abstract Graphite has been used in gas-cooled nuclear reactors as a neutron moderator. The dismantling of nuclear reactors will generate significant amounts of graphite waste. Neutron irradiation is responsible for 14C formation in graphite, and it leads to severe structural and nanostructural degradations. At high neutron fluence, nanoporous turbostratic carbon is formed from original lamellar graphite. This phase is supposed to be especially 14C enriched. An original 14C extraction process was proposed: to “decontaminate” graphite waste from 14C by selectively gasifying such degraded areas, without entirely consuming the graphite waste. To specify the operating conditions, milled graphite was used as a nonradioactive analogue. Raman microspectrometry and transmission electron microscopy techniques show that neutron irradiation and milling lead to similar multiscale organization, and especially nanoporous carbon formation. Thermogravimetry experiments were then carried out between 800 and 1100 °C, at a CO2 pressure of 0.1 MPa. To determine the best temperature range allowing a nanoporous component selective gasification, Raman microspectrometry analysis was coupled with transmission electron microscopy observations on the residues obtained for each gasification temperature. The 950-1000 °C temperature range is the most efficient allowing a complete elimination of degraded areas supposed to be representative of nuclear graphite waste 14C-rich areas.

Abstract: A simple, direct and environmentally-friendly one-pot preparation of a palladium-containing mesoporous carbon (Pd@MC) from a cheap, non-hazardous and easily accessible biopolymer (tannin) as a carbon precursor, Pluronic[registered sign] F127 surfactant as a pore structuring agent and a palladium salt is reported. This material has the peculiarity to have palladium nanoparticles entrapped in irregular voids connected to the worm-like mesoporous network limiting palladium leaching while keeping good access to the reactants. It was successfully used as a catalyst for ligand-free Suzuki-Miyaura couplings of aryl bromides in a green solvent (propane-1,2-diol) in the presence of extremely low amounts of supported palladium (usually 30 [small mu ]equiv.). It is noteworthy that almost palladium-free products (containing less than 1.5 [small mu ]equiv. of precious metal) can be obtained. The possibility to reuse the catalyst was also ascertained.

Friction behaviour of TiAlN films around cubic/hexagonal transition: A 2D grazing incidence X-ray diffraction and electron energy loss spectroscopy study 2015 Thin Solid Films
Vol. 577, pp. 74-81 
article  
Abstract: The properties at different scales of Ti1-xAlxN films deposited by reactive magnetron sputtering from TiAl sintered (S) targets produced by powder metallurgy are compared with those of a set of films previously deposited in the same conditions from mosaic targets (M) made of pure Ti and Al metals. For compositions close to the hcp/fcc transition (around x = 0.6), the friction behaviour, growth directions and organization of crystallized domains are found to be sensitive to the type of target used. The resistance to crack creation is higher for Ti0.54Al0.46N (S) and Ti0.38Al0.62N (S) than for Ti0.50Al0.50N (M) and Ti0.32Al0.68N (M). From the measurement of mechanical properties, toughness, and wear volumes and from the observation of wear tracks, it is found that films prepared from sintered targets exhibit a better wear resistance. Grazing incidence X-ray diffraction and electron energy loss spectroscopy in Transmission Electronic Microscopy are used to investigate the long- and short-range orders within the films. The morphology of Ti0.54Al0.46N (S) film can be considered as an array of crystalline domains having reciprocal-space vectors 111 and 200 directed along the meridian but with random in-plane orientation. Ti0.38Al0.62N (S) Al-rich film presents a random orientation of the crystalline domains whereas Ti0.32Al0.68N (M) deposited from composite targets exhibits a well-oriented fibrillar structure. The N K-edge Electron Energy Loss Near Edge Spectra are discussed with previous results of Extended X-ray Absorption Fine Structure Spectroscopy, which has evidenced different values of Al-N and Ti-N bond lengths, either octahedral (cubic-like) or tetrahedral (hexagonal-like) within Ti0.50Al0.50N (M) and Ti0.32Al0.68N (M) films. For similar compositions, films deposited from sintered alloys contain more nitrogen atoms in octahedral cubic-like environment than coatings made from mosaic targets, which could explain their better resistance to cracking, higher hardness and better wear resistance.

Abstract: Abstract The functionalization of carbon nanomaterials in controlled and selective manner and in order to stabilize small metal nanoparticles is of high interest particularly in the catalysis field. We present the μ-waves assisted few layer graphene (FLG) oxidation in water, which results in a partial sheets exfoliation and formation of oxygen functionalized carbon nanoballs, supported on highly graphitized graphene sheets. This double morphology material allows homogenous anchoring of Pt nanoparticles, while the advantages of planar and highly crystallized FLG are preserved. For comparison, acid treated FLG (conventional heating) exhibits highly hydrophobic and inert surface with carboxylic groups as anchoring sides localized at the FLG edges. Despite similar oxygen content, the performed physicochemical analyses depict different nature and localization of the oxygen/defects functionalities introduced in water (in μ-waves) and acid treated FLGs. Finally, the addition of FLG during the preparation of Pt particles-carried out by μ-wave assisted polyol method yields small nanoparticles with average size of 1 nm.

Abstract: An exploitation of the generally unwanted sensitivity to light of chain-end functions in polymers synthesized by reversible addition-fragmentation chain transfer (RAFT) is proposed. This reactivity can be purposely enhanced through the simple introduction of a strongly absorbing chromophore on the terminal monomer unit. The concept was validated on RAFT polymers with a xanthate chain-end function and a terminal monomer unit derived from N-vinylcarbazole (NVC). We demonstrate that such compounds can be considered as efficient and versatile macrophotoinitiators, being able to initiate both free radical and radical promoted cationic polymerizations under UV irradiation.

Abstract: A green photoinduced method for the modification of a biodegradable and biocompatible polymer, Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) has been successfully carried out using two types of monomers with potential antibacterial effects, i.e., 2-[(methacryloyloxy)-ethyl] trimethylammonium chloride (META) and an ampicillin-derived monomer. The photografting process is conducted through a photoinduced free-radical process employing a thiocarbamate-based photoinitiator in an aqueous medium. Under appropriate conditions, radicals are generated from the PHBHV surface, thus initiating the UV-mediated photopolymerization of methacrylate or methylacrylamide-derived monomers from the surface of PHBHV films. The photochemical mechanism of the thiocarbamate photolysis is entirely described by the electron spin resonance/spin-trapping technique and laser flash photolysis, and the modified-PHBHV films are extensively characterized by fluorescence experiments, water contact angle, and XPS measurements. Finally, a primary investigation is conducted to support the antibacterial property of the new functionalized films against Escherichia coli and Staphylococcus aureus, and their cytocompatibility with NIH-3T3 fibroblastic cells is evaluated.

Vol. 67, pp. 61-70 
article DOI  
Abstract: Nowadays, methods to determine the air gap thickness based on the 3D body scanning lack an extensive evaluation of the measurement uncertainty imposed by the scanner and computational algorithms. In our study, we propose an evaluation strategy for full body scanning techniques using two 3D scanners: Vitus XXL and Artec MHT. The performance evaluation of the 3D scanner together with the accompanying post-processing method included the repeatability of the 3D scanner for complex anatomic shapes, and determination of fabric thickness and contact area. Our newly developed method, which includes scanning, post-processing of scans and the determination of distance between skin and garment surfaces, is highly repeatable in case of both scanners (up to 1 mm depending on the scanner). The method can account for the thickness of fine fabrics of the same thickness magnitude as the scanner accuracy, which resulted in accurate determination of the garment contact area.

Vol. 53(6), pp. 1052-1062 
article DOI  
Abstract: Dyes often act as the photoinitiator PI/photosensitizer PS in photopolymer materials and are therefore of significant interest. The properties of the PI/PS used strongly influences grating formation when the material layer is exposed holographically. In this paper, the ability of a recently synthesized dye, D 1, to sensitize an acrylamide/polyvinyl alcohol (AA/PVA) based photopolymer is examined, and the material performance is characterized using an extended nonlocal photopolymerization-driven diffusion model. Electron spin resonance spin-trapping (ESR-ST) experiments are also carried out to characterize the generation of the initiator/primary radical, R-center dot, during exposure. The results obtained are then compared with those for the corresponding situation when using a xanthene dye, i.e., erythrosine B, under the same experiment conditions. The results indicate that the nonlocal effect is greater when this new photosensitizer is used in the material. Analysis indicates that this is the case because of the dye's (D_1) weak absorptivity and the resulting slow rate of primary radical production. (C) 2014 Optical Society of America

Querido, W., Farina, M. and Anselme, K. Strontium ranelate improves the interaction of osteoblastic cells with titanium substrates: Increase in cell proliferation, differentiation and matrix mineralization 2015 Biomatter
Vol. -Biomatter, pp. 00-00 
article DOI URL 
Abstract: AbstractWe describe direct effects of strontium ranelate on the interaction of osteoblastic cells with different titanium substrates. Our goal was to better understand the potential of this drug for improving the efficacy of bone implants. Treatment was done with 0.12 and 0.5 mM Sr2+ of strontium ranelate in cell culture. We analyzed cell response to the drug on titanium substrates with surface topographies obtained using acid etching, electro-erosion processing, sandblasting, and machine-tooling. Treatment preserved the initial cell adhesion to the substrates, cell shape parameters (area, aspect ratio, circularity, and solidity), and the orientation of cells on grooved surfaces. However, both concentrations of the drug increased cell proliferation in all substrates. Moreover, a dose-dependent increase in alkaline phosphatase activity and in the production of mineralized matrix with typical features of bone tissue was shown. The observed effects were similar in the different substrates. In conclusion, strontium ranelate improved the interaction of osteoblastic cells with titanium substrates, increasing cell proliferation and differentiation into mature osteoblasts and the production of bone-like mineralized matrix for all substrates. This study highlights a promising role of strontium ranelate on enhancing the clinical success of bone implants, particularly in patients with osteoporosis.

Treatment preserved the initial cell adhesion to the substrates, cell shape parameters (area, aspect ratio, circularity, and solidity), and the orientation of cells on grooved surfaces. However, both concentrations of the drug increased cell proliferation in all substrates. Moreover, a dose-dependent increase in alkaline phosphatase activity and in the production of mineralized matrix with typical features of bone tissue was shown. The observed effects were similar in the different substrates. In conclusion, strontium ranelate improved the interaction of osteoblastic cells with titanium substrates, increasing cell proliferation and differentiation into mature osteoblasts and the production of bone-like mineralized matrix for all substrates. This study highlights a promising role of strontium ranelate on enhancing the clinical success of bone implants, particularly in patients with osteoporosis.

Abstract: Abstract A novel approach for a controlled growth of pattern-directed organization of Ag nanocrystals (NCs) onto rigid substrate has been proposed to achieve large-scale functional materials. A soft nanoporous template was used to create first a hexagonal array of gold nanoparticles by a seed-mediated growth colloidal process. The size and morphology of the Ag NCs were then controlled by a site-selective heterogeneous nucleation and growth onto the Au precursors. While removing the nanoporous polymer mask before the growth process leads to the formation of Ag flower-shape crystals, keeping this thin polymer mask rather leads to the formation of sheet-like structures. The growth mechanism of the template-directed synthesis of Ag crystals arrays was investigated. In addition, the optical properties of Ag NCs arrays were discussed in relation to their morphology and organization. Finally, this facile and simple multistep approach is particularly attractive due to its environmentally gentle processing conditions and represents an open pathway to several technologically large-scale nanomaterials fabrication such as hierarchically ordered crystal architectures for sensor applications.

Abstract: Abstract This study aims at determining suitable conditions for the preparation of the best organobeidellite starting material used for the development of efficient mesoporous TiO2 supported beidellite (Bd) photocatalysts. For this purpose, organo-modifications of natural Bd from Agadir Basin (Morocco) were achieved. The influence of (i) the length of alkyl chains Cn (n = 8, 12, 14 and 16) of n-alkyl ammonium surfactants CH3(CH2)n-1NH3+ and (ii) the amount of C16 surfactant ranging from 1 to 5 times the smectite (Sm) cation exchange capacity (CEC) on the structure of organo- Bd was studied. XRD, TEM, TG-DTA and FTIR results are consistent with the intercalation of cationic surfactants species in Bd interlayer spaces according to different conformations yielding to their expansion. The interlayer expansion magnitude increased both with the length of alkyl chain and the amount of C16 surfactant. Organomodification with increasing surfactant load beyond 1CEC besides yielded to the adsorption of increasing excess on external surfaces of Bd particles. These controlled structural modifications will be used further in the functionalization of this Bd by TiO2 nanoparticles to produce efficient supported TiO2-Bd photocatalysts.

Abstract: Abstract This work deals with the study of the effect of the amount of cethyltrimethylammonium bromide (CTAB) surfactant, used in the preparation of starting organobeidellites, on physico-chemical properties and photocatalytic activity of TiO2 supported beidellite (Bd) nanocomposites against the removal of Orange G (OG) dye from aqueous media. A structural study of organobeidellites used as starting materials was reported in a companion paper. Here, physico-chemical characterizations of the nanocomposite photocatalysts show that TiO2 supported on Bd beforehand organomodified with an amount of CTAB equivalent to 3 CEC of smectite (3CTA+-Bd) exhibits thin fine grained (≈ 10 nm) features which remarkably remained stable in the form of photoactive anatase up to 750 °C. Comparatively, the TiO2 coating grown on Bd previously rendered organophilic by using an amount of CTAB equivalent to 5 CEC of Clay mineral (5CTA+-Bd) appears thicker and more porous with larger nanoparticles (≈ 25 nm) which is prone to be readily converted into less photoactive rutile as observed near 700 °C. This is likely due to its development mainly outside Bd interlayer spaces promoted by outer organophilic environment created by the adsorption of CTA+ excess. In both cases, anatase is still present as minor phase up to 900 °C. As a result of these differences a significant improvement of the photocatalytic activity of TiO2 supported Bd nanocomposite prepared starting from 3CTA+-Bd is observed compared to that from 5CTA+-Bd. For instance, the total elimination of the pollutant from the aqueous solution occurs within about 45 min when using the 3CTA+-Bd-TiO2 photocatalyst instead of 90 min using the 5CTA+-Bd-TiO2 sample. Furthermore, the best TiO2-Bd supported photocatalyst is also found more efficient than a pure TiO2 xerogel sample.

Vol. 9379, pp. SPIE 
article DOI  
Abstract: In this work, the trapping efficiency of new fiber optical tweezers structures fabricated using photo polymerization and focused ion beam milling techniques is evaluated. The first fabrication methods may present limited capabilities on the tailoring of the structures, and therefore limited operation features. On the other hand, with focused ion beam milling a vast myriad of structures may be accurately fabricated, and contrarily to conventional fabrication methods, more specialized manipulation tools can be developed. In this regard, the performance of FOT for the trapping of yeast cells using spherical lenses (photo polymerization) and spiral phase lenses (FIB) will be presented. In addition, finite difference time domain (FDTD) simulations of the full vectorial optical propagation through the designed structures and the corresponding calculation of the optical forces are presented and different designs are evaluated.

Vol. 31(1), pp. 529-534

Abstract: Noble metal nanoparticles with ligand shells are of interest for applications in catalysis, thermo-plasmonics, and others, involving heating processes. To gain insight into the structure-formation processes in such systems, self-assembly of carbohydrate-functionalized gold nanoparticles during precipitation from solution and during further heating to ca. 340 degrees C was explored by in situ combination of nanobeam SAXS/WAXS and nanocalorimetry. Upon precipitation from solution, X-ray scattering reveals the appearance of small 2D domains of close-packed nanoparticles. During heating, increasing interpenetration of the nanoparticle soft shells in the domains is observed up to ca. 81 degrees C, followed by cluster formation at ca. 125 degrees C, which transform into crystalline gold nuclei at around 160 degrees C. Above ca. 200 degrees C, one observes the onset of coalescence and grain growth resulting in gold crystallites of average size of about 100 nm. The observed microstructural changes are in agreement with the in situ heat capacity measurements with nanocalorimetry.

Endogenous Stable Radicals for Characterization of Thermally Carbonized Porous Silicon by Solid-State Dynamic Nuclear Polarization C-13 NMR 2015 Journal of Physical Chemistry C
Vol. 119(33), pp. 19272-19278

Abstract: As with all nanomaterials, characterization of the surface chemistry of mesoporous silicon (PSi) is crucial for the development in its diverse applications. Nuclear magnetic resonance (NMR) is one of the most powerful methods to study the chemistry of nanomaterials, but it is currently underutilized with PSi due to low signal-to-noise ratios achieved with this material which lead to very long measurement times. Here we show that endogenous radicals exist in thermally carbonized PSi and demonstrate the feasibility of solid-state dynamic nuclear polarization (DNP) NMR without addition of organic radicals. Use of DNP NMR is demonstrated to highly improve the signal-to-noise ratio while significantly reducing the measurement times. This technique opens new possibilities for the use of more advanced NMR techniques allowing the detailed characterization of complex materials such as PSi. Furthermore, the chemical structure of thermally carbonized PSi is studied by complementary techniques, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and Raman spectroscopy.

Vol. 39(4), pp. 2675-2681 
article URL 
Abstract: FAU-type zeolite (NaX) materials were synthesized in the presence of 5 organosilane surfactants [(CH3O)3SiC3H6N(CH3)2-CxH2x+1]Cl (x = 4, 8, 12, 16, 18) (denoted QASiCx) in order to introduce intracrystalline mesoporosity in the FAU-type structure. The influence of the nature of organosilane surfactants (length of the alkyl chain) and their concentrations in the synthesis medium was investigated to determine their impact on the formation of hierarchical FAU-type zeolite nanosheets. Under the basic conditions of faujasite X synthesis, (CH3O)3Si- bonds hydrolyze to -Si-OH, and yield -Si-O-Al- and -Si-O-Si-linkages that anchor to a zeolite framework. These linkages and the formation of micelles by the alkyl chains of the surfactants lead to the formation of mesopores and inhibition of the NaX crystallite growth, leading to the formation of FAU-type nanosheets depending on the alkyl chain length. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed that FAU-type zeolite nanosheets were obtained only using surfactants composed of a minimum twelve carbon alkyl chain. X-ray diffraction results revealed that the optimum concentration of the organosilane to obtain a pure FAU-type material is 0.011 M. Above this concentration, the impurity phase and amorphous materials are observed. This simple approach paves a new way for obtaining hierarchical zeolite materials of controlled porosity by a direct approach for specific catalytic applications.

Vol. 17(7), pp. 1-10 
article URL 
Abstract: ZnO nanoparticles (NP) with different morphologies such as nanorods (NR), isotropic NP, and cloud-like (CL) structures have been synthesized by an organometallic route. The prepared ZnO nanostructures have been deposited on miniaturized silicon gas sensor substrates by an inkjet method, and their responses to CO, C3H8, and NH3 gases have been studied at different operating temperatures (340-500 °C) and relative humidity of 50 %. It is noteworthy that the morphology of the nanostructure of the sensitive layer is maintained after thermal treatment. The morphology of ZnO NP significantly influences the sensor response level and their selectivity properties to reducing gases. Among the three different ZnO types, sensors prepared with NR show the highest response to both CO and C3H8. Sensors made of isotropic NP and CL structures show a lower but similar response to CO. From all investigated nanostructures, sensors made of CL structures show the weakest response to C3H8. With NH3 gas, no effect of the morphology of the ZnO sensitive layer has been evidenced. These different responses highlight the important role of the nanostructure of the ZnO sensitive layer and the nature of the target gas on the detection properties of the sensors.

Vol. 5(5), pp. 451-456 
article DOI  
Abstract: The determination of the surface free energy of zeolite membranes is a key parameter to determine the solutes affinity with the active filtration layer. Flat mordenite (MOR-type) zeolite membranes were synthesized on a-alumina platelets by deep coating methodology. These membranes have undergone an alkali treatment. Surface and textural characterizations were performed before and after the mild alkali treatment in order to evaluate the modifications of the zeolite structure, surface charge and polarity. Results showed that the mild alkali treatment increases the hydrophilicity of Na-mordenite surface. The OWRK (Owens, Wendt, Rabel and Kaelble) method allowed following the variation of the polar component of the free energy due to the extraction of silicon atoms from the zeolite framework. These results contribute strongly in the understanding of mass transport in porous tubular ultrafiltration (UF)/nanofiltration (NF) zeolite membranes.

Vol. 428, pp. 71-79 
article DOI  
Abstract: This work is dedicated to the development of MFI-type structure zeolite films (single-layer or bilayer) on the internal layer of a specific macroporous alumina tubular support for nanofiltration applications. The bottom MFI layer was obtained by direct hydrothermal synthesis while a secondary growth method was used for the top MFI layer. A complete characterization of the obtained MFI membranes (single-layer or bilayer) is proposed using various techniques, such as X-ray diffraction, scanning electron microscopy, mercury porosimetry and nitrogen sorption measurements. Dense and highly crystallized films of MFI-type structure zeolite were obtained for both single-layer and bilayer MFI films. The total film thickness were around 7.1 +/- 0.5 mu m and 14.5 +/- 1 mu m for single-layer and bilayer MFI films respectively. The Si/Al molar ratio of the MFI films varied between 185 and 305 for single-layer and bilayer MFI films respectively. The hydraulic permeability of the tubular MFI membrane was achieved by the filtration of pure water. The hydraulic permeability of the single-layer and bilayer MFI membranes decreased rapidly at the beginning of the conditioning process, and stabilized at 1.08 x 10(-14) m(3) m(-2) and 1.02 x 10(-15) m(3) m(-2) after 15 h and the rejection rates of neutral solute (Vb 12) are 10% and 50% for the single-layer and bilayer MFI films respectively.

Abstract: A simple methodology for encapsulating ca. 10 nm-sized superparamagnetic Fe3O4 nanoparticles in zeolitic imidazolate frameworks (ZIF-8) crystals was developed. The corresponding Fe3O4@ZIF-8 heterostructured material exhibits bifunctional properties with both high magnetization (Fe3O4) and high thermal stability, large specific surface, and catalytic properties (ZIF-8). The Fe3O4@ZIF-8 catalyst exhibits fair separation ability and reusability, which can be repeatedly applied for Knoevenagel condensations and Huisgen cycloadditions for at least ten successive cycles.

Vol. 5(3), pp. 1829-1839 
article DOI  
Abstract: Cu2+-doped zeolitic imidazolate framework (ZIF) crystals were efficiently prepared by reaction of Cu(NO3)(2), Zn(NO3)(2), and 2-methylimidazole in methanol at room temperature. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction showed that the Cu/ZIF-8 particles were nanosized (between ca. 120 and 170 nm) and that the body-centered cubic crystal lattice of the parent ZIF-8 framework is continuously maintained, regardless of the doping percentage. Moreover, thermogravimetric analyses and specific BET surface area measurements demonstrated that the doping does not alter the high stability of ZIF-8 crystals and that the porosity only decreases at a high doping percentage (25% in Cu2+). The Cu/ZIF-8 material showed excellent catalytic activity in the [3 + 2] cycloaddition of organic azides with alkynes and in Friedlander and Combes condensations due to the high catalyst surface area and the high dispersion of Cu/ZIF-8 particles. Notably, the Cu/ZIF-8 particles not only exhibit excellent performance but also show great stability in the reaction, allowing their reuse up to ten times in condensation reactions. Our findings explored a simple and powerful way to incorporate metal ions into the backbones of open framework materials without losing their properties.

Abstract: A simple methodology for encapsulating ca. 10 nm-sized superparamagnetic Fe3O4 nanoparticles in zeolitic imidazolate frameworks (ZIF-8) crystals was developed. The corresponding Fe3O4@ZIF-8 heterostructured material exhibits bifunctional properties with both high magnetization (Fe3O4) and high thermal stability, large specific surface, and catalytic properties (ZIF-8). The Fe3O4@ZIF-8 catalyst exhibits fair separation ability and reusability, which can be repeatedly applied for Knoevenagel condensations and Huisgen cycloadditions for at least ten successive cycles. © The Royal Society of Chemistry 2015.

Vol. -(-), pp. n/a-n/a 
article URL 
Abstract: The formation of two-dimensional (2D)-hexagonal (p6m) silica-based hybrid material with a dual-mesoporosity is investigated in situ using synchrotron time-resolved Small Angle X-ray Scattering (SAXS). The material is synthesized from a mixed micellar solution of a nonionic fluorinated surfactant, RF₈(EO)₉, and a nonionic triblock copolymer, P123. Both mesoporosities, with pores dimensions at 3.3 and 8.5 nm respectively, are seen by Nitrogen sorption, TEM and SAXS. The in situ SAXS experiments reveal a mesophase formation in two steps. First the nucleation and growth of a primary 2D-hexagonal network (N1) associated to mixed micelles containing P123, then followed by the formation of the second network (N2) associated to micelles of pure RF₈(EO)₉. The data obtained from SAXS and TEM suggest that N1 is used as nucleation centers for the formation of N2, that would result in the formation of a grain with both mesoporosities. Understanding the formation mechanism of such material is an important step towards the synthesis of more complex materials with a fine tuning of the porosity.

Abstract: Five dissymmetrically functionalized anthracene analogues (3a--e) were synthesized from commercially available 9,10-dibromoanthracene through an efficient bromine--iodine exchange followed by two successive Sonogashira coupling reactions. The resulting TMS-anthracene analogues are interesting building blocks for the preparation of highly π-conjugated dissymmetric pentacene-based dyads, which could be used as active semiconducting layers for organic field-effect transistors (OFETs).

Abstract: The hydrometalation of alkynes with group 14 elements such as tin- or silyl hydrides is a classical transformation in organic synthesis. Strangely, among the group 14 elements, the use of germanium hydrides is rarely seen. Two efficient, stereodivergent, and broadly applicable routes to (Z)- and (E)-alpha-CF3-vinylgermanes by regio- and stereoselective hydrogermylation of alpha-trifluoromethylated alkynes under radical or transition-metal-catalyzed conditions are reported. Furthermore, we demonstrate that the resulting stereodefined fluorinated building blocks are remarkable cross-coupling partners, provided that the vinylgermane is appropriately tuned electronically, as demonstrated by the synthesis of trisubstituted (Z)- and (E)-alpha-trifluoromethylated alkenes.

Vol. 132(9), pp. 41542 
article DOI  
Abstract: The present study deals with the optimization of polyimide (PI) mechanical properties, obtained by Spark Plasma Sintering (SPS), by using a method combining Design of Experiments (DOE) with physical, structural, and mechanical characterizations. The effects of SPS parameters such as temperature, pressure, dwell time, and cooling rate on the density, mechanical properties, and structure of PI were investigated. The experimental results revealed that the mechanical properties of the material were optimized by raising the sintering temperature up to 350 degrees C. The optimized SPS processing parameters were a temperature of 350 degrees C, a pressure of 40 MPa, and a dwell time of 5 min. Under these conditions, a relative density of 99.6% was reached within only a few minutes. The corresponding mechanical properties consisted of Young's modulus of 3.43 GPa, a Shore D hardness of 87.3, and a compressive strength of 738 MPa for a maximum compressive strain of 61.8%. Moreover, when working at 320 degrees C and at 100 MPa, an increase in the dwell time was necessary to enhance the properties. Contrary to the other parameters, the cooling rate appeared to be a non-significant parameter. Finally, correlations between the PI structure and the mechanical properties were made to demonstrate the densification mechanisms. (c) 2014 Wiley Periodicals, Inc. J. Appl. Polym.

Abstract: The development of multilayered polymeric/metallic materials by a PM route employing spark plasma sintering (SPS) has been explored. The aim is to produce composites that join a polymer with a metal for structural applications. In a first approach, the consolidation of polyimide-based composites by SPS was studied. For temperatures as low as 350uC, homogeneous mechanical properties were achieved in compression tests. In a second set of experiments, multilayered polyimide/aluminium composites were consolidated by SPS. These polymerbased composites could be used as an interlayer material to join effectively polyimide and aluminium.

Vol. 64(7), pp. 1616-1622 
article DOI URL 
Abstract: New homogeneous water-soluble polyvinylpyrrolidone composites containing iron sulfur nitrosyl complexes as nitric oxide donors with antitumor and antiseptic activities were synthesized. The morphology of the composites in the solid state was examined by X-ray diffraction and scanning electron microscopy. The study by small-angle X-ray scattering showed that samples of the composites do not contain 10--100-nm aggregates and that iron sulfur nitrosyl complexes are uniformly distributed in polymer matrices. The percentage of NO-releasing iron sulfur nitrosyl complexes in the composites was determined by ESR spectroscopy. An amperometric analysis demonstrated that the polymer composites decompose to yield NO within a few seconds after the dissolution in water without additional thermal and photoactivation. The dependences of the amount of NO and the maximum level of NO release on the duration of the storage of aqueous solutions for all of the synthesized films were determined at pH 7.0. Some of the synthesized polymer composites retain NO-donor activity of the starting pharmacologically active iron nitrosyl complexes and can be recommended to be used as targeted delivery systems of this class of compounds to biological targets.

Vol. 119The Journal of Physical Chemistry C, pp. 22596-22603 
article DOI URL 
Abstract: By combining atomic force microscopy experiments and full-atomistic computer simulations, we compared the two-dimensional (2D) ordering dynamics of two variants of supra-molecular polymers of bis-urea molecules which differed only by a single cisdouble bond in their side groups. At early stages of ordering, the double bonds favored kinks at the level of individual molecules which induced transient steric constraints hindering the spontaneous formation of long supra-molecular polymers. In addition, due to these kinks, molecule-substrate interactions were disturbed. At later stages, however, due to a progressively increasing number of established directional hydrogen bonds (HBs) between molecules, the self-assembly process improved and thereby increased the length of the supra-molecular polymers. Large domains of micrometer-long and aligned supra-molecular polymers were formed, epitaxially guided by the graphite substrate and having a constant width consistent with the length of the molecule. Thus, introducing flexible (kinked) side chains can reduce the nucleation probability and slow down growth of supra-molecular polymers due to incommensurablility with the crystalline substrate. Such an elementary control of nucleation and growth via the introduction of a single double bond epresents a powerful pathway for the formation of large ordered domains of aligned 1D supra-molecular polymers.

Vol. 199(0), pp. 77-86 
article URL 
Abstract: Abstract The goal of this work was to study the thermal stabilization of calcium apatites in which the Ca2+ ions were substituted for Sr2+ in increasing concentrations via ionic co-substitutions. Two distinct standard syntheses were proposed for comparative purposes: one using counter-ions that were not easily incorporated into the apatite structure (NH4+/NO3−) and one using counter-ions that can be easily incorporated into the structure (Na+/Cl−). After calcination, only the apatites synthesized in the presence of NH4+/NO3− presented phase transformation. In contrast, the apatites synthesized in the presence of Na+/Cl− formed a solid solution after calcination, with Na+, Ca2+, Sr2+ and Cl− sharing the same apatite lattice. Wavelength dispersive X-ray fluorescence spectroscopy (WDXRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and temperature-programmed desorption (TPD) techniques showed that the counter-ions present during the syntheses that are associated with CO32− play an important role in the thermal stabilization of the apatites.

Vol. 7(1), pp. 911-920 
article DOI  
Abstract: The lifetime of bone implants inside the human body is directly related to their osseointegration. Ideally, future materials should be inspired by human tissues and provide the material structurefunction relationship from which synthetic advanced biomimetic materials capable of replacing, repairing, or regenerating human tissues can be produced. This work describes the development of biomimetic thin coatings on titanium implants to improve implant osseointegration. The assembly of an inorganicorganic biomimetic structure by UV laser pulses is reported. The structure consists of a hydroxyapatite (HA) film grown onto a titanium substrate by pulsed-laser deposition (PLD) and activated by a top fibronectin (FN) coating deposited by matrix-assisted pulsed laser evaporation (MAPLE). A pulsed KrF* laser source (lambda = 248 nm, tau = 25 ns) was employed at fluences of 7 and 0.7J/cm(2) for HA and FN transfer, respectively. Films approximately 1500 and 450 nm thick were obtained for HA and FN, respectively. A new cryogenic temperature-programmed desorption mass spectrometry analysis method was employed to accurately measure the quantity of immobilized protein. We determined that less than 7 mu g FN per cm(2) HA surface is adequate to improve adhesion, spreading, and differentiation of osteoprogenitor cells. We believe that the proposed fabrication method opens the door to combining and immobilizing two or more inorganic and organic materials on a solid substrate in a well-defined manner. The flexibility of this method enables the synthesis of new hybrid materials by simply tailoring the irradiation conditions according to the thermo-physical properties of the starting materials.

Vol. 280(0), pp. 748-754 
article DOI URL 
Abstract: Abstract The aim of the study is to examine the adsorption capacity of hydroxycinnamic compounds (ferulic acid, p-coumaric acid, cinnamic acid) on zeolite adsorbents (FAU- and ∗BEA-type structure) versus Amberlite resin XAD16. The pH and contact time effects on adsorption were evaluated. The adsorption capacity was dependent on pH and higher at pH less than pKa1. The kinetic adsorption is faster onto FAU and ∗BEA zeolites than onto XAD16 resin. Maximum adsorption capacities were calculated for the target compounds for pH=3.5 by using the Langmuir isotherm model. They reached higher values for zeolites than for XAD16 and are respectively of 139, 122 and 109 mg g-1 for ferulic, p-coumaric and cinnamic acids. Values around 30 mg g-1 were observed for XAD16. Desorption ratios are close to 100% for ∗BEA zeolite and XAD16 resin in the presence of ethanol 96%. The use of regenerated zeolites leads to a loss of adsorption capacities of 30% for the cinnamic acid and 20% for the two other acids. It was concluded that ∗BEA zeolites are particularly interesting adsorbants to isolate the hydroxycinnamic compounds from vegetal extracts.

Vol. 17(22), pp. 14495-14501 
article URL 
Abstract: Among the 2D crystals, silicene, which forms sp2-sp3 bonds, is expected to present a higher reactivity than graphene, characterized by sp2 bonds only. However, silicene functionalization, in particular with organic molecules, remains an open question. By means of density functional theory, we study the adsorption of benzene, a model organic molecule, on (3 [times] 3) silicene on the (4 [times] 4) Ag(111) surface. Our calculations show that the dispersion interactions must be taken into account in order to describe this system properly. The adsorption energy is calculated by means of the semi-empirical dispersion-corrected density functional theory (DFT-D2) and the optB86b-vdW density functional. The charge density and electron localization function maps indicate that the molecule is chemisorbed on the silicene surface by means of two Si-C covalent bonds. In agreement with charge density difference calculations, two C-C double bonds are formed in the benzene molecule, which adopts a butterfly configuration. The silicene lattice is slightly deformed upon benzene adsorption, but the Si-Si distance remains the same as in bare silicene/Ag(111). Bader analysis shows a charge transfer from top Si atoms to both molecules and Ag substrates. Finally, we show that the covalent functionalization of silicene is possible.

Abstract: Within density functional theory, the adsorption of the H2Pc molecule on the (3 × 3) silicene/(4 × 4) Ag(111) surface has been investigated. We observe an electronic redistribution in the central macrocycle of the H2Pc molecule and the formation of two Si − N covalent bonds between the molecule and the silicene, in agreement with a cycloaddition reaction. However, while on SiC(0001)(3 × 3) or Si(111)(3√×3√)R30 °-boron, the H2Pc molecule remains planar, and the H2Pc molecule takes a butterfly conformation on the silicene/Ag substrate due to an electrostatic or a polarization repulsion between the molecule and the silicene. Our study opens a way to the experimental adsorption of large organic molecules on supported silicene.

Structure and optical properties of thin poly(p-xylylene) - Silver nanocomposite films prepared by low-temperature vapor deposition polymerization 2015 Polymer
Vol. 71, pp. 60-69

Abstract: In this study, variable-temperature grazing-incidence X-ray diffraction, transmission electron and scanning force microscopy were employed to address the semicrystalline structure and surface morphology of thin poly(p-xylylene) - silver nanocomposite films with Ag concentrations up to 12 vol.%. It was observed that the dominant crystalline modification of poly(p-xylylene) in the studied films is alpha-form, which is in contrast to thick poly(p-xylylene) films deposited at liquid nitrogen temperature where beta-form prevails. The films exhibit planar texture that can be further enhanced on annealing. The optical properties of the films were studied by UV-vis and IR-spectroscopy. It was found that the samples display surface plasmon resonance, with the peak wavelength in the range of 435-445 nm. The peak positions undergo a redshift upon a long-term storage under ambient conditions. The IR-spectroscopy reveals the bands, which can be assigned to the vibrations of oxygen-containing groups, with intensity increasing with silver content. (C) 2015 Elsevier Ltd. All rights reserved.

Vol. 284, pp. 574-581

Abstract: Abstract Nanocrystalline lithium iron silicate/carbon (Li2FeSiO4/C) composites were successfully prepared by impregnation of a commercial porous carbon using ethanolic solutions of the different metallic precursors, followed by thermal annealing at 600 °C. The effects of Li2FeSiO4 loading content on the structure and organization of the Li2FeSiO4/C composites at the nanoscale were investigated. Through optimization of the synthesis conditions, small Li2FeSiO4 nanocrystals (4-12 nm) are formed and well dispersed in the porous conductive carbon. The electrochemical performances of these composites were tested as positive electrodes for lithium-ion batteries. The Li2FeSiO4/C composite with the lowest Li2FeSiO4 loading exhibits the best rate capability with a significant capacity contribution from carbon. It was found that the presence of carbon delays the lowering of the Fe3+/Fe2+ redox voltage usually reported for Li2FeSiO4 (from 3.1/3.0 to 2.8/2.7 V vs. Li+/Li), due to a stabilization effect of the initial Li2FeSiO4 crystal structure. For the Li2FeSiO4/C composite (81/19 weight ratio), a discharge capacity of 81 mAh g−1 can be achieved at 55 °C for a charge/discharge rate of 2C, with 86% capacity retention after 500 cycles, showing the positive effect of the porous carbon addition for long term cycling stability.

Photoredox catalysis using a new iridium complex as an efficient toolbox for radical, cationic and controlled polymerizations under soft blue to green lights 2015 Polymer Chemistry
Vol. 6(4), pp. 613-624 
article DOI  
Abstract: A new iridium complex (nIr) was designed and investigated as a photoinitiator catalyst for radical and cationic polymerizations upon very soft irradiations (lights ranging from 457 to 532 nm). A ring-opening polymerization (ROP) of an epoxy monomer was easily promoted through the interaction between nlr and an iodonium salt (Iod) upon light. The addition of N-vinylcarbazole (NVK) enhances the performance. In radical polymerization, nIr can be efficient in combination with phenacyl bromide (PBr) and optionally an amine: these photoinitiating systems work according to an original oxidative cycle and a regeneration of nIr is observed. A control of the methyl methacrylate polymerization (conducted under a 462 nm light) with 1.2-1.6 polydispersity indexes was displayed. Surface modifications by direct laser write was also easily carried out for the first time through surface re-initiation experiments, i.e. the dormant species being reactivated by light in the presence of nIr; the polymer surfaces were analyzed by XPS. The chemical mechanisms were examined through laser flash photolysis, NMR, ESR and size exclusion chromatography experiments.

Influence of Electronic Effects on the Reactivity of Triazolylidene-Boryl Radicals: Consequences for the use of N-Heterocyclic Carbene Boranes in Organic and Polymer Synthesis 2015 Chemistry-a European Journal
Vol. 21(39), pp. 13772-13777 
article DOI  
Abstract: A small library of triazolylidene-boranes that differ only in the nature of the aryl group on the external nitrogen atom was prepared. Their reactivity as hydrogen-atom donors, as well as that of the corresponding N-heterocyclic carbene (NHC)-boryl radicals toward methyl acrylate and oxygen, was investigated by laser flash photolysis, molecular orbital calculations, and ESR spin-trapping experiments, and benchmarked relative to the already known dimethyltriazolylidene-borane. The new NHC-boranes were also used as co-initiators for the TypeI photopolymerization of acrylates. This allowed a structure-reactivity relationship with regard to the substitution pattern of the NHC to be established and the role of electronic effects in the reactivity of NHC-boryl radicals to be probed. Although their rate of addition to methyl acrylate depends on their electronegativity, the radicals are all nucleophilic and good initiators for photopolymerization reactions.

article DOI URL 
Abstract: We report on the use of an alkoxyamine (AA) for fabrication of functional micropatterns with complex structures by UV mask lithography. The living character of the polymer surface and the vertical spatial control of the repolymerization reaction from few tens of nanometers to few micrometers were demonstrated. The impact of the main parameters governing the controlled polymerization and the reinitiation process activated by light or heat was investigated. Micropatterning is shown to be a powerful method to investigate the physicochemical molecular phenomena. It is possible to control the polymer microstructure thickness from few tens of nanometers to few micrometers. In the last section, some applications are provided showing the potential of the AA for generating covalently bonded hydrophilic/hydrophobic micropatterns or luminescent surfaces. This demonstrates the high versatility and interest of this route.

Vol. 15, pp. 266-277 
article DOI  
Abstract: Infections associated with implanted medical devices are a major cause of nosocomial infections, with serious medical and economic repercussions. A variety of silver-containing coatings have been proposed to decrease the risk of infection by hindering bacterial adhesion and biofilm formation. However, the therapeutic range of silver is relatively narrow and it is important to minimize the amount of silver in the coatings, in order to keep sufficient antibacterial activity without inducing cytotoxicity. In this study, the antibacterial efficiency and biocompatibility of nanocoatings with minimal silver loading (similar to 0.65 nmol cm(-2)) was evaluated in vitro and in vivo. Titanium substrates were coated by grafting mercaptododecylphosphonic acid (MDPA) monolayers followed by post-reaction with AgNO3. The MDPA/AgNO3 nanocoatings significantly inhibited Escherichia coil and Staphylococcus epidermidis adhesion and biofilm formation in vitro, while allowing attachment and proliferation of MC3T3-E1 preosteoblasts. Moreover, osteogenic differentiation of MC3T3 cells and murine mesenchymal stem cells was not affected by the nanocoatings. Sterilization by ethylene oxide did not alter the antibacterial activity and biocompatibility of the nanocoatings. After subcutaneous implantation of the materials in mice, we demonstrated that MDPA/AgNO3 nanocoatings exhibit significant antibacterial activity and excellent biocompatibility, both in vitro and in vivo, after postoperative seeding with S. epidermidis. These results confirm the interest of coating strategies involving subnanomolar amounts of silver exposed at the extreme surface for preventing bacterial adhesion and biofilm formation on metallic or ceramic medical devices without compromising their biocompatibility.

In vitro and in vivo evaluation of the inflammatory potential of various nanoporous hydroxyapatite biomaterials 2015 Nanomedicine
Vol. 10(5)Nanomedicine, pp. 785-802 
article DOI URL 
Abstract: Aim: To discriminate the most important physicochemical parameters for bone reconstruction, the inflammatory potential of seven nanoporous hydroxyapatite powders synthesized by hard or soft templating was evaluated both in vitro and in vivo. Materials & methods: After physical and chemical characterization of the powders, we studied the production of inflammatory mediators by human primary monocytes after 4 and 24 h in contact with powders, and the host response after 2 weeks implantation in a mouse critical size defect model. Results: In vitro results highlighted increases in the secretion of TNF-α, IL-1, -8, -10 and proMMP-2 and -9 and decreases in the secretion of IL-6 only for powders prepared by hard templating. In vivo observations confirmed an extensive inflammatory tissue reaction and a strong resorption for the most inflammatory powder in vitro. Conclusion: These findings highlight that the most critical physicochemical parameters for these nanoporous hydroxyapatite are, the crystallinity that controls dissolution potential, the specific surface area and the size and shape of crystallites.

Vol. 6(7), pp. 1171-1179 
article DOI  
Abstract: Four different 2-amino-1H-benzo[de]isoquinoline-1,3(2H)-dione derivatives (NDNs) bearing nitro-or amino-substituents have been prepared and incorporated into photoinitiating systems together with an iodonium salt, N-vinylcarbazole, an amine or 2,4,6-tris(trichloromethyl)-1,3,5-triazine. The ring-opening cationic polymerization of epoxides as well as the free radical polymerization of acrylates upon exposure to various visible LEDs (e.g. LEDs at 405 nm, 455 nm or 470 nm) could be performed. Reactions under green or red light (e.g. laser diodes at 532 or 635 nm) are also feasible. Compared to the well-known camphorquinone-based systems, some of the novel NDN-based combinations employed here exhibit a much higher polymerization efficiency. A panchromatic behavior can also be observed with a specifically designed compound bearing two nitro groups (e.g. radical polymerization or thiol-ene processes can be promoted upon blue, green or red light). This outstanding performance paves the way to polymerization under soft conditions. Their photochemical properties and structure/efficiency relationships have been investigated using steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis, and electron spin resonance spin trapping techniques.

Vol. 41, pp. 32-66 
article DOI  
Abstract: Although there have been many reports on photoinitiating systems adapted to visible lights for radical photopolymerization, the challenge for the design and development of photoinitiating systems for cationic photopolymerization or concomitant radical/cationic photopolymerization (for interpenetrating polymer network IPN synthesis) with visible lights still remains open. Particularly, the recent development of cheap and easily accessible LEDs operating upon soft visible light irradiations has opened new fields for polymer synthesis. Since 2011, many novel photoinitiating systems based on organic and organometallic compounds with excellent visible light absorption have emerged and exhibited outstanding photoinitiating abilities especially for cationic photopolymerization. In this review, recent progress (mainly from 2011 to early 2014) in applications of photoinitiators and sensitive photoinitiating systems under visible lights are reported. In addition, their relative efficiencies in the photopolymerization of different monomers are exemplified and discussed. (C) 2014 Elsevier Ltd. All rights reserved.

Abstract: Naphthalimide-phthalimide derivatives (NDPDs) have been synthesized and combined with an iodonium salt, N-vinylcarbazole, amine or 2,4,6-tris(trichloromethyl)-1,3,5-triazine to produce reactive species (i.e., radicals and cations). These generated reactive species are capable of initiating the cationic polymerization of epoxides and/or the radical polymerization of acrylates upon exposure to very soft polychromatic visible lights or blue lights. Compared with the well-known camphorquinone based systems used as references, the novel NDPD based combinations employed here demonstrate clearly higher efficiencies for the cationic polymerization of epoxides under air as well as the radical polymerization of acrylates. Remarkably, one of the NDPDs (i.e., NDPD2) based systems is characterized by an outstanding reactivity. The structure/reactivity/efficiency relationships of the investigated NDPDs were studied by fluorescence, cyclic voltammetry, laser flash photolysis, electron spin resonance spin trapping, and steady state photolysis techniques.

Abstract: Isoquinolinone derivatives bearing amino- or nitro- substituent (IQNs) have been synthesized as photoinitiators and combined with various additives (i.e., iodonium salt, N-vinylcarbazole, amine or 2,4,6-tris(trichloromethyl)−1,3,5-triazine) to initiate ring-opening cationic polymerizations (CP) or free radical polymerizations under exposure to visible LEDs (e.g., LEDs at 405 nm or 455 nm, or cold white LED) or a halogen lamp. Compared to the well-known camphorquinone-based systems, the novel IQNs-based combinations employed here demonstrate higher efficiencies for the CP of epoxides. The photochemically generated reactive species (i.e., cations and radicals) from the IQNs-based systems have been investigated by steady state photolysis, cyclic voltammetry, fluorescence, laser flash photolysis, and electron spin resonance spin trapping techniques. The structure/reactivity/photoinitiating ability relationships of IQNs-based combinations are also discussed; the crucial role of the excited state lifetimes of the photoinitiators to ensure efficient quenching by additives is clearly underlined. © 2015 Wiley Periodicals, Inc.

Abstract: Naphthalimide derivatives (NDAs) with amino- or alkylthio-substituents have been synthesized and combined in photoinitiating systems (PIS) with an iodonium salt, N-vinylcarbazole, an amine, or 2,4,6-tris(trichloromethyl)-1,3,5-triazine to produce radicals, cation radicals, or cations. The photochemical mechanisms are investigated by fluorescence, cyclic voltammetry, laser flash photolysis, electron spin resonance spin trapping, and steady state photolysis techniques. The generated reactive species are capable of initiating the cationic polymerization (CP) of epoxides under air or the free radical polymerization (FRP) of acrylates in laminate upon exposure to visible lights delivered by a halogen lamp, a cold white light-emitting diode (LED), or LEDs at 385, 395, 405, 455, or 470 nm. Compared to the well-known camphorquinone based systems, the novel NDA containing PISs exhibit higher efficiencies both for CP and FRP. Remarkably, the photobleaching of some NDAs is significant, and colorless final polymer coatings are obtained. The structure/photochemical property relationships of NDAs are discussed in detail (redox potentials, fluorescence, rate constants of reactions, etc.) to shed some light on their respective photoinitiating ability.

Abstract: Only one naphthalic anhydride derivative has been reported as light sensitive photoinitiator, this prompted us to further explore the possibility to prepare a new family of photoinitiators based on this scaffold. Therefore, eight naphthalic Naphthalic anhydride derivatives (ANH1-ANH8) have been prepared and combined with an iodonium salt (and optionally N-vinylcarbazole) or an amine (and optionally 2,4,6-tris(trichloromethyl)-1,3,5-triazine) to initiate the cationic polymerization of epoxides and the free radical polymerization of acrylates under different irradiation sources, that is, very soft halogen lamp (∼ 12 mW cm−2), laser diode at 405 nm (∼1.5 mW cm−2) or blue LED centered at 455 nm (80 mW cm−2). The ANH6 based photoinitiating systems are particularly efficient for the cationic and the radical photopolymerizations, and even better than that of the well-known camphorquinone based systems. The photochemical mechanisms associated with the chemical structure/photopolymerization efficiency relationships are studied by steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis, and electron spin resonance spin-trapping techniques. © 2015 Wiley Periodicals, Inc.

Vol. 36(18), pp. 1675-1680 
article URL 
Abstract: N-vinylcarbazole (NVK) can act simultaneously as a photoinitiator, an additive, and a mono­mer (photoinaddimer) of photopolymerization upon exposure to the household ultraviolet (UV) light-emitting diode (LED) bulb (emission wavelength centered at 392 nm). Even though the light absorption spectrum of NVK exhibits weak overlapping with the emission spectrum of the UV LED, the active species (i.e., radicals and cations) can be generated from the interaction between NVK and diphenyliodonium hexafluorophosphate (Iod) under irradiation of this LED device, which is investigated by steady state photolysis and electron spin resonance spin-trapping methods. Interestingly, the generated radicals and cations from the NVK/Iod system demonstrate high efficiency to initiate the free radical photopolymerization of (meth)acrylates and the cationic photopolymerization of epoxide and divinyl ether under the UV LED irradiation, and the one-step simultaneous catonic/radical photopolymerization of expoxide/acrylate blend can lead to the formation of tack free polyacrylate/polyether-based interpenetrated polymer network film within 10 min even when the polymerization process is exposed to the atmosphere highlighting the high efficiency of the system to reduce the oxygen inhibition effect. More interestingly, NVK/Iod system can also initiate the photopolymerization of NVK under the UV LED irradiation to produce polyvinylcarbazole, and NVK acts as both a photoinitiator and a monomer in the system.

Vol. 48(7), pp. 1972-1980 
article DOI  
Abstract: A new type of photocatalyzed Cu-based atom transfer radical polymerization (ATRP) is described, involving directly the light absorption of the activator form of the copper complex Cu(I). The selected catalyst was bis(1,10-phenanthroline)copper(I), Cu(phen)(2)(+)(,) due to its intense absorption in the visible domain, which permitted to use very soft irradiation conditions, consisting of a simple household blue LED at 0.9 W. An excellent control over the polymerization of methyl methacrylate (MMA) in dimethylformamide (DMF) was observed under irradiation in these conditions, using ethyl alpha-bromophenylacetate (EBPA) as the initiator, with polydispersity indexes (PDI) as low as 1.10 while using low catalyst content (80 ppm). The proposed mechanism implies first the formation under irradiation of the excited state of the activator form of the complex Cu(I)*. It can then rapidly undergo the oxidative quenching of the alkyl bromide, which results in its conversion into the deactivator form of the complex Cu(II)-Br along with the generation of a propagating radical. The setting up of the ATRP equilibrium ensues. Additionally, it was possible to complete the catalysis mechanism by adding triethylamine (TEA), which permitted a faster polymerization, thanks to a faster regeneration of the activator Cu(I). An excellent control over the polymerization was also observed in the presence of TEA, with PDI as low as 1.06. The addition of TEA allowed also to use a catalyst loading as low as 20 ppm, while maintaining a good controllability.

Vol. 47(1), pp. 82-86 
article DOI  
Abstract: We report on the growth of palladium nanoparticles on the basal plane of as-cleaved highly oriented pyrolytic graphite (HOPG) samples, and on CO2 ion sputtered nanostructured HOPG surfaces. The morphology of Pd nanostructures grown at room temperature is investigated by scanning tunneling microscopy (STM). The STM observations indicate that the morphology of the Pd films is strongly dependent on the HOPG surface. Stabilized Pd particles only form on the sputtered surface, while ramified Pd particles decorate the clean HOPG terraces. The prestructuring of HOPG surface leads to a selective location of particles at the rim of the nanopits generated by the CO2 ion sputtering and annealing of the surface. The correlation between size, form, density, spatial distribution of the Pd nanoparticles and the quantity of metal added on surface is discussed. We also describe trench channeling of graphite or graphene basal planes by means of Pd nanoparticles in an ambient environment. Copyright (c) 2014 John Wiley & Sons, Ltd.

Abstract: Full characterization of nanostructured organosilicon luminophores NOL4 and NOL5 based on the donor 2,2’-bithiophene and acceptor 1,4-bis(2,2′- bithiophene-5-yl)benzene units in dilute solutions and thin films by UV-Vis spectroscopy, DSC, TGA and X-ray techniques was reported. It was found that usage of these molecules as dopants (10–20 wt%) to the electroactive polyfluorene host in organic light-emitting devices (OLEDs) leads to the efficient spectral long wavelength shifting of the electroluminescence and an increase of the OLED performance as compared to the devices based on pristine polyfluorene, NOL4 and NOL5.

Vol. 53(1), pp. 42-49 
article DOI  
Abstract: Six iron complexes (FeCs) with various ligands have been designed and synthesized. In combination with additives (e.g., iodonium salt, N-vinylcarbazole, amine, or chloro triazine), the FeC-based systems are able to efficiently generate radicals, cations, and radical cations on a near UV or visible light-emitting diode (LED) exposure. These systems are characterized by an unprecedented reactivity, that is, for very low content 0.02% FeC-based systems is still highly efficient in photopolymerization contrary to the most famous reference systems (Bisacylphosphine oxide) illustrating the performance of the proposed catalytic approach. This work paves the way for polymerization in soft conditions (e.g., on LED irradiation). These FeC-based systems exhibit photocatalytic properties, undergo the formation of radicals, radical cations, and cations and can operate through oxidation or/and reduction cycles. The photochemical mechanisms for the formation of the initiating species are studied using steady state photolysis, cyclic voltammetry, electron spin resonance spin trapping, and laser flash photolysis techniques.

article DOI  
Abstract: Seven naphthalimide derivatives (NDP1-NDP7) with different substituents have been designed as versatile photoinitiators (PIs), and some of them when combined with an iodonium salt (and optionally N-vinylcarbazole) or an amine (and optionally chlorotriazine) are expected to exhibit an enhanced efficiency to initiate the cationic polymerization of epoxides and the free radical polymerization of acrylates under different irradiation sources (i.e., the LED at 385, 395, 405, 455, or 470 nm or the polychromatic visible light from the halogen lamp). Remarkably, some studied naphthalimide derivative based photoinitiating systems (PIS) are even more efficient than the commercial type I photoinitiator bisacylphosphine oxide and the well-known camphorquinone-based systems for cationic or radical photopolymerization. A good efficiency upon a LED projector at 405 nm used in 3D printers is also found: a 3D object can be easily created through an additive process where the final object is constructed by coating down successive layers of material. As another example of their broad potential, a NDP compound enveloped in a cyclodextrin (CD) cavity, leads to a NDP-CD complex which appears as a very efficient water-soluble photoinitiator when combined with methyldiethanol amine to form a hydrogel. The high interest of the present photoinitiator (NDP2) is its very high reactivity, allowing synthesis in water upon LED irradiation as a green way for polymer synthesis.The structure/reactivity/efficiency relationships as well as the photochemical mechanisms associated with the generation of the active species (radicals or cations) are studied by different techniques including steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis, and electron spin resonance spin-trapping methods.

Vol. 53(14), pp. 1719-1727 
article URL 
Abstract: N,N'-dibutylquinacridone (DBQA) is utilized here for the first time as a high-performance panchromatic photoinitiator for the cationic polymerization (CP) of epoxides, the free radical polymerization (FRP) of acrylates, the thiol-ene polymerization and the synthesis of interpenetrated polymer networks (epoxide/acrylate) under violet, blue, green and yellow lights (emitted from LED at 405 nm, 470 nm, 520 nm, or 594 nm, or laser diode at 532 nm). It confers a panchromatic character to the photopolymerizable matrices. Remarkably, the proposed DBQA based photoinitiating systems exhibit quite excellent efficiency (the final monomer conversion for multifunctional monomers at room temperature can reach 62% and 50% in CP and FRP, respectively) and appear as much more powerful than the camphorquinone or Eosin-Y containing reference systems for visible light. For green light, DBQA is much more reactive than the literature reference (Eosin-Y) and for blue light, a good reactivity is found compared with camphorquinone. The photochemical mechanisms are studied by molecular orbital calculations, steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis, and electron spin resonance spin trapping techniques. © 2015 Wiley Periodicals, Inc.

LED-Induced Polymerization (385, 405, and 455 nm) Using Star-Shaped Tris(4-(thiophen-2-yl)phenyl)amine Derivatives as Light-Harvesting Photoinitiators 2015 Macromolecular Chemistry and Physics
Vol. 216(2), pp. 218-227

Abstract: Two star-shaped tris(4-(thiophen-2-yl)phenyl)amine derivatives, namely tris(4-(5-(3-pentylthieno[3,2-b]thiophen-5-yl)thiophen-2-yl)phenyl) amine and tris(4-(5-(3-pentyl-2-(thiophen-2-yl)thieno[3,2-b]thiophen-5-yl) thiophen-2-yl) phenyl) amine, are developed as photoinitiators for radical and cationic polymerizations under near-UV and visible light-emitting diodes (LEDs) (e.g., 385, 405, and 455 nm). When used in combination with an iodonium salt (and optionally N-vinyl carbazole) or an amine/alkyl halide couples, they lead to excellent photoinitiating abilities for the polymerization of epoxides or (meth) acrylates under air. Compared with commercial photoinitiators, i.e., camphorquinone-based systems or bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide, the novel photoinitiators exhibit noticeably higher polymerization efficiencies under air (epoxide conversions = 41-57% vs approximate to 0%, halogen lamp exposure; methacrylate conversions = 50-55% vs 44%, LED at 405 nm exposure; methacrylate conversions = 34-42% vs 0-8%, LED at 455 nm exposure). These systems are also interesting in overcoming oxygen inhibition. The photochemical mechanisms are studied by steady-state photolysis, electron spin resonance spin trapping, fluorescence, cyclic voltammetry, and laser flash photolysis techniques.

Abstract: A benzophenone-naphthalimide derivative (BPND) bearing tertiary amine groups has been developed as a high-performance photoinitiator in combination with 2,4,6-tris(trichloromethyl)-1,3,5-triazine or an iodonium salt for both the free radical polymerization (FRP) of acrylates and the cationic polymerization (CP) of epoxides upon exposure to near UV and visible LEDs (385-470 nm). BPND can even produce radicals without any added hydrogen donor. The photochemical mechanisms are studied by molecular orbital calculations, steady state photolysis, electron spin resonance spin trapping, fluorescence, cyclic voltammetry and laser flash photolysis techniques. These novel BPND based photoinitiating systems exhibit an efficiency higher than that of the well-known camphorquinone-based systems (FRP and CP) or comparable to that of bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide (FRP at 455 nm).

Vol. 4(0), pp. 101-108 
article URL 
Abstract: Abstract A series of diketopyrrolopyrrole derivatives (DPPs) and indigo derivatives (IDGs) are synthesized and applied as photoinitiators (PIs) for the cationic polymerization (CP) of epoxides, the free radical polymerization (FRP) of acrylates or the thiol-ene polymerization under different lights (purple, blue, green, yellow, red LEDs and green laser diode). The photochemical mechanisms involved in the presence of these PIs and additives (iodonium salt (Iod), N-vinylcarbazole (NVK), amine (MDEA) or 2,4,6-tris(trichloromethyl)-1,3,5-triazine (R-Cl)) are investigated by steady state photolysis, electron spin resonance spin trapping, fluorescence, cyclic voltammetry, and laser flash photolysis techniques. Real-time infrared spectroscopy studies reveal that DPP4/Iod/NVK is very efficient for both CP and FRP and, compared to two references (Eosin-Y and camphorquinone), displays noticeably higher polymerization efficiencies. Panchromatic curable formulations exhibiting an almost constant photosensitivity from the blue to the red are proposed.

Vol. 6(28), pp. 5053-5061 
article URL 
Abstract: Curcumin exhibits broad ground state light absorption and can act as a photoinitiator for the free radical photopolymerization of methacrylates under air upon exposure to different household LED bulbs. The effects of temperature and various additives on the photoinitiation efficiency of curcumin-based systems have been investigated. The curcumin-based system exhibits the highest photoinitiation efficiency at 25 [degree]C. Additives also play an important role in the photoinitiation efficiency, and well-designed systems can even demonstrate higher efficiency than the commercial type I photoinitiator [phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (XBPO)] and type II photoinitiator [camphorquinone (CQ)]. Interestingly, the curcumin/diphenyliodonium hexafluorophosphate/triphenylphosphine combination is a capable multicolor photoinitiating system able to initiate free radical photopolymerization under air upon exposure to UV, blue, green, yellow, red, and warm white household LED bulbs. In addition, reversible addition-fragmentation chain transfer (RAFT) photopolymerization of N-isopropylacrylamide can also be achieved using a curcumin-based system under the irradiation of a blue LED bulb. The photochemical mechanisms associated with the generation of radicals from the investigated photoinitiating systems are investigated by different techniques (fluorescence, steady state photolysis, and electron spin resonance spin-trapping methods) and discussed in detail. More interestingly, the polymer sample produced through the photopolymerization process using the curcumin-based photoinitiating system demonstrates almost no toxicity to human fibroblast Hs-27 cells, endowing this photoinitiating system with great potential for the fabrication of biocompatible polymeric materials.

Vol. 90, pp. 310-317 
article DOI  
Abstract: We investigate the interface between Au catalysts and a Ge(111) substrate. This system is achieved by dewetting an Au layer above the Au-Ge eutectic temperature. We show by high resolution transmission electron microscopy that a large amount of Ge can be moved over a surface of Ge(111) by using assistance of eutectic Au-Ge droplets. This localization is achieved thanks to the ability of nano Au-Ge droplets to incorporate a large amount of Ge and to release it by cooling down the sample at room temperature. This makes the localization process irreversible with respect to annealing at a very high temperature. The extra Ge supplied by precipitation is in epitaxy with the Ge(111) substrate. This reflects in macroscopic I(Y) measurements. (C) 2015 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.

Vol. 119(32), pp. 18091-18098 
article DOI  
Abstract: MgH2 nanoparticles with different average sizes have been prepared as ordered microporous carbon by tuning the Mg amount from 15 to 50 wt %. Ultrasmall particles with mean sizes of 1.3 and 3.0 nm have been obtained for 15 and 25 wt % Mg contents, respectively. The hydrogen desorption properties strongly depend on the nanoparticle size, as evidenced by different thermal analysis techniques. The onset temperature of hydrogen desorption for MgH2 nanoparticles below 3 nm occurs at a temperature about 245 K lower than for microcrystalline material. Two distinct hydrogen desorption peaks are noticed for nanoparticles with mean sizes of 1.3 and 3.0 nm, as confirmed by TDS and HP-DSC. H-1 NMR investigations suggest the presence of two MgH2 populations with enhanced hydrogen mobility, as compared to the microcrystalline hydride. The short hydrogen diffusion path and the enhanced hydrogen mobility may explain the increased desorption kinetics of these ultrasmall nanoparticles.

Abstract: Rh-based nanoparticles supported on a porous carbon host were prepared with tunable average sizes ranging from 1.3 to 3.0 nm. Depending on the vacuum or hydrogen environment during thermal treatment, either Rh metal or hydride is formed at nanoscale, respectively. In contrast to bulk Rh that can form a hydride phase under 4 GPa pressure, the metallic Rh nanoparticles (?2.3 nm) absorb hydrogen and form a hydride phase at pressure below 0.1 MPa, as evidenced by the presence of a plateau pressure in the pressure?composition isotherm curves at room temperature. Larger metal nanoparticles (?3.0 nm) form only a solid solution with hydrogen under similar conditions. This suggests a nanoscale effect that drastically changes the Rh?H thermodynamics. The nanosized Rh hydride phase is stable at room temperature and only desorbs hydrogen above 175 °C. Within the present hydride particle size range (1.3?2.3 nm), the hydrogen desorption is size-dependent, as proven by different thermal analysis techniques.

Abstract: Pd90Co10 and Pd75Co25 nanoalloys embedded into mesoporous carbon hosts have been prepd. by two synthetic methods: direct and indirect. The av. nanoparticles size can be tuned by both the temp. during thermal treatment and the chem. compn.: the higher the treatment temp. and the richer the Pd compn., the larger the nanoparticle size. Twofold size- and compn.-dependence of the hydrogen sorption properties at room temp. are evidenced. The Co substitution in Pd nanoalloys increases the equil. pressure at room temp. relative to nanosized Pd. The hydrogen sorption capacity decreases by Co substitution in Pd, as also demonstrated by SQS + DFT calcns. [on SciFinder(R)]

Vol. 75(10), pp. 1081-1087 
article DOI  
Abstract: We report a facile synthesis of ZnO/Fe2O3 heterostructures based on the hydrolysis of FeCl3 in the presence of ZnO nanoparticles. The material structure, composition, and its optical properties have been examined by means of transmission electron microscopy, scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy and diffuse reflectance UV-visible spectroscopy. Results obtained show that 2.9 nm-sized Fe2O3 nanoparticles produced assemble with ZnO to form ZnO/Fe2O3 heterostructures. We have evaluated the photodegradation performances of ZnO/Fe2O3 materials using salicylic acid under UV-light. ZnO/Fe2O3 heterostructures exhibited enhanced photocatalytic capabilities than commercial ZnO due to the effective electron/hole separation at the interfaces of ZnO/Fe2O3 allowing the enhanced hydroxyl and superoxide radicals production from the heterostructure.

Vol. 104(8), pp. 082902 
article DOI  
Abstract: We report an interesting effect in the form of a rise (up to 13%) in the permittivity of graphene (GE) filled polyvinylidene difluoride trifluoroethylene (P(VDF-TrFE)) subjected to a small uniaxial deformation (up to 7% in the principal direction). Our findings differ from GE-PVDF homopolymer samples that show a decrease of permittivity upon elongation. We argue that the VDF content which controls the spontaneous polarization has a profound effect on the charge storage through the addition of interface density by the GE phase.

Vol. 54(0), pp. 71-78 
article URL 
Abstract: The influence of rod-like SBA-15 type ordered mesoporous silica particles, as additives, on the morphology and textural parameters of electrospun polyacrylonitrile (PAN) nanofibers has been studied. PAN charged-webs are prepared by electrospinning of a dispersion of SBA-15 particles in a solution of PAN in DMF. The effect of the applied voltage on the morphology of produced webs has been also investigated. Collected results demonstrate that when electrospinning pristine or charged PAN, the higher the voltage applied, the coarser the fiber is. As a result, sub-micron fibers of PAN charged with SBA-15 particles were obtained. An increase, to some extent, of the specific surface area and pore volume of charged fibers compared to that of pristine electrospun PAN fibers has been also observed. Thermogravimetric analyses reveal that more than 78% of SBA-15 particles are found in the dry fibers. SBA-15 loading rates of 14.3, 15.6 and 27.6 wt.% were achieved. Calculations done to estimate the ratio of accessible pore of SBA-15 particles incorporated within the produced fibers show that more than 50% of accessible pores can be obtained. However, there is a saturated capacity of SBA-15 particles distribution on the surface of the nanofibers beyond 15.6 wt.% loading of SBA-15.This suggests that the ratio of accessible pores within the charged fibers is also limited.

Anselme, K. and Bigerelle, M. On the Relation Between Surface Roughness of Metallic Substrates and Adhesion of Human Primary Bone Cells 2014 Scanning
Vol. 36(1), pp. 11-20 
article DOI  
Abstract: Surface characteristics of materials, whether their topography, chemistry, or surface energy, play an essential part in osteoblast adhesion on biomaterials. Thus, the quality of cell adhesion will influence the cell's capacity to proliferate and differentiate in contact with a biomaterial. We have developed for more than ten years numerous studies on the influence of topography and chemistry of metallic substrates on the response of primary human bone cells. The originality of our approach is that contrary to most of other authors, we quantified the adhesion of primary human bone cells on metallic substrates with perfectly characterized surface topography after some hours but also over 21 days. Moreover, we have developed original statistical approaches for characterizing the relation between surface roughness and cell-adhesion parameters. In this article, we will illustrate different studies we did these last ten years concerning the development of a new adhesion parameter, the adhesion power; the correlation between short-term adhesion, long-term adhesion, and proliferation; the influence of roughness organization on cell adhesion and the development of the order parameter; our modeling approach of cell adhesion on surface topography; the relative influence of surface chemistry and topography on cell adhesion and contact angle; the relation between surface features dimensions and cell adhesion. Further, some considerations will be given on the methods for scanning surface topography for cell-adhesion studies. Finally, perspectives will be given to elucidate these intracellular mechanotransduction mechanisms induced by the deformation of cells on model sinusoidal peaks-or-valleys surfaces.

Vol. 72, pp. 31-34 
article DOI  
Abstract: ZnO nanowires bent to a complex shape and held in place by static friction force from supporting flat surface are investigated experimentally and theoretically. The complex shapes are obtained by bending the nanowires inside a scanning electron microscope with a sharp tip attached to a nanopositioner. Several methods previously described in the literature are applied along with author's original method to calculate the distributed friction force and stored elastic energy in the nanowires from the bending profile. This comparative study evidences the importance of the usage of appropriate models for accurate analysis of the nanowires profile. It is demonstrated that incomplete models can lead up to an order of magnitude error in the calculated friction force for complex profiles. (C) 2013 Elsevier Ltd. All rights reserved.

Vol. 2(2), pp. 120-125 
article DOI  
Abstract: In this paper, the phase transformation in water at low temperature from amorphous TiO2 to semi-crystalline anatase is reported. Our approach is an environmentally friendly low energy consumer process that requires no specific devices or instrumentation. The phase transition occurs even at room temperature. However, the higher the temperature is, the better the crystallinity is. Crystallization of amorphous titania occurs through a rearrangement of the TiO62- octahedral units in amorphous TiO2. The phase transformation is catalyzed by water, which adsorbs on the titania surface to form bridges between the surface OH groups of different octaedra. The obtained titania samples have been used for the photodegradation of methyl orange. Because of the formation of anatase, mesoporous TiO2 exhibits a photocatalytic activity after treatment in water. However, the activity is lower than that of the standard photocatalysts because the TiO2 treated during 1 h in water at 120 C has degraded 85% of methyl orange within 240 mm compared to 45 min for P25.

Vol. 5(4), pp. 1-5 
article  
Abstract: Anti-reflecting layers deposited on flat surfaces make molecular films visible in reflecting light microscopy. For centuries, single Anti-Reflecting layers have been implicitly associated with dielectric materials. We recently demonstrated that anti-reflecting layers could be achieved out of absorbing materials such as metals as well, but only when used as backside layers where illumination and detection are performed through a supporting window. Fortunately, this corresponds to the best geometry when envisaging biophotonic or electrochemical applications at the solid/liquid interface. Here we explain how single absorbing anti-reflecting layers can serve each of these applications, and both simultaneously.

Vol. 562(0), pp. 668-673 
article URL 
Abstract: Abstract We report here on the atomic migration and associated nucleation mechanisms of Si nanocrystals on LaAlO3(001) surface, a high-κ crystalline oxide. Chemical and structural properties were investigated using X-ray photoelectron spectroscopy, X-ray photoelectron diffraction (XPD), reflection high-energy electron diffraction (RHEED), and ex situ with atomic force microscopy. The Si deposition was achieved by molecular beam epitaxy at room temperature. The morphological and chemical properties were followed as a function of isochronal post-growth annealing at increasing temperatures up to 800 °C by 100 °C steps. Up to 500 °C the Si layer remains amorphous without any interdiffusion and interfacial alloy formation. Above 500 °C Si nanocrystals nucleate on the surface by transformation of the amorphous Si layer into Si crystalline islands. Two kinds of annealing treatments were performed (direct current and electronic bombardment), leading to a better crystal quality (without stacking faults or twins) for a direct current heating process. Finally, a preferential epitaxial relationship between LaAlO3 and the Si islands was deduced by RHEED and confirmed by XPD: Si(001) planes are parallel to the LaAlO3(001) surface and rotated by 45° around the [001] growth axis.

Abstract: We report the epitaxial growth of one Silicon monolayer on the LaAlO 3(111) substrate, a high-κ crystalline oxide. Structural and chemical properties were investigated in-situ using reflection high energy electron diffraction (RHEED) and X-ray photoelectron spectroscopy (XPS). The deposition was achieved by molecular beam epitaxy in the temperature range RT-500°C. A two-dimensional epitaxial growth mode is observed for a deposition at temperature between 300°C and 500°C.

Vol. 131(13), pp. 40499 
article DOI  
Abstract: Open cell foams obtained by the simultaneous coreaction of condensed flavonoid tannins with an alkoxylated fatty amine and polymeric diphenylmethane isocyanate yielded highly flexible/elastic polyurethane foams. Copolymerized amine/isocyanate/tannin oligomers were identified by C-13 NMR and MALDI-TOF spectroscopy. In general, between 30% and 50% of natural tannins is added to the components used to obtain polymerisation of the polyurethane. The characteristic of these new, partially biosourced polyurethanes is that the tannin present slows down burning, some of them can be made flame self-extinguishing and if burning they neither flow nor asperge flaming material around, contrary to what occurs with normal polyurethanes. This limits the possibility of transmitting fire to other materials in the same environment. Cyclic compression tests were carried out showing that after 50 cycles foam recovery was in excess of 80%.

Vol. 61, pp. 352-360 
article DOI  
Abstract: Highly flexible films and strongly adhering surface finishes were prepared by reacting partially aminated polyflavonoid tannins with furfuryl alcohol in the presence of plasticisers such as glycerol or polyethylene imine. C-13 NMR analysis showed partial amination of the tannin under the conditions used and even the formation of some -N= bridges between flavonoids, although these were shown to be rare. MALDI-TOF analysis showed the presence of oligomers produced by the reaction of furfuryl alcohol with the flavonoids and the simultaneous self-condensation of furfuryl alcohol. Thus linear methylene-furanic chains were also found to be linked to flavonoid reactive sites. Furthermore, side condensation reactions of furfuryl alcohol lead to the formation of methylene ether bridges between furanic nuclei, followed by rearrangement to methylene bridges with liberation of formaldehyde. This latter reacts with both the reactive sites of the flavonoid and of the furane rings to yield -CH2OH and -CH2+ groups and methylene bridges. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 12(2), pp. 717-726 
article DOI  
Abstract: Activated carbons were prepared from date pits by physical activation with CO2 and the textural properties were investigated by BET and D-R methods with N-2 and CO2 adsorption isotherms. The interaction of the NO2 with activated carbon was examined at ambient temperature and the effect of operating conditions such as temperature and inlet gas compositions was also examined. It was observed that the development of porosity with increasing time of activation favours the adsorption capacity of NO2. The maximum adsorption capacity reached was about 107 mg/g, which is higher than several activated carbon prepared from classical lignocellulosic biomass. However, a slight decrease of NO2 adsorption capacity was observed with increasing temperature. The addition of oxygen into the inlet gas gave rise to an increase in amount adsorbed of NO2.

Belhachemi, M., Jeguirim, M., Limousy, L. and Addoun, F. Comparison of NO2 removal using date pits activated carbon and modified commercialized activated carbon via different preparation methods: Effect of porosity and surface chemistry 2014 Chemical Engineering Journal
Vol. 253, pp. 121-129 
article DOI  
Abstract: This study aims to evaluate the NO2 adsorption capacities of activated carbons prepared by physical and chemical activation of date pits and to compare them with modified commercialized activated carbons. The texture, morphology and surface chemistry of the different carbons were evaluated by N-2 and CO2 adsorption, scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), temperature programmed desorption coupled with mass spectroscopy (TPD MS), Fourier transform infrared spectroscopy (FTIR) and X-ray fluorescence (XRF) techniques. The obtained results show that activated carbon prepared from date pits are an efficient adsorbents for the removal of NO2 from the exhaust gases at ambient temperature. The obtained adsorption capacities are close to the ones obtained for the commercialized activated carbons. The analysis of the correlation between NO2 adsorption capacities and the textural and the surface chemistry properties shows that a higher microporosity volume, an homogenous microporosity and the presence of stable oxygen groups contribute strongly to the adsorption of NO2 on the activated carbon surface. In contrast, the presence of strong acidic groups such as carboxylic, anhydrides and lactones inhibits the reduction of NO2 into NO, which represents a crucial step for the NO2 adsorption.

Vol. 55(0)8th International Conference on Material Sciences, CSM8-ISM5, pp. 220-226 
article URL 
Abstract: Abstract Cassava and tree cassava starch films plasticized with glycerol were produced by casting method. Different glycerol contents (30, 35, 40 and 45 wt. % on starch dry basis) were used and the resulting films were fully characterized. Their water barrier and mechanical properties were compared. While increasing glycerol concentration, moisture content, water solubility, water vapour permeability, tensile strength, percent elongation at break and Young's modulus decreased for both cassava and tree cassava films. Tree cassava films presented better values of water vapour permeability, water solubility and percent elongation at break compared to those of cassava films, regardless of the glycerol content.

Vol. 351, pp. 82-87 
article DOI  
Abstract: The present survey highlights for the first time that glucamine-modified ordered mesoporous silica (OMS) type SBA-15 can be used as adsorbents for the uptake of boron from water. By means of X-ray diffraction, N-2 adsorption-desorption, thermogravimetry and Fourier transform infrared, the structure and physicochemical properties of the materials were characterized. The behavior of the calcined and glucamine modified SBA-15 in adsorption of boron from synthetic solutions and seawater was investigated. Physico-chemical parameters such as adsorbent dose, equilibrium contact time, pH and initial boron concentration were studied in a series of batch adsorption experiments. Boron adsorption on the adsorbent was saturated within 3 h in solution containing 10 mg L-1 of boron, with 5 g L-1 of adsorbent dose. The studies showed that boron were quantitatively removed from water at neutral pH. The glucamine modified SBA-15 possessed higher boron removal capacity, about 45%, than the unmodified SBA-15 which showed only a 23% of boron removal. Thanks to the increase of the adsorption sites due to the grafting. Desorption tests were carried out using 1 M HCl. OMS type SBA-15 was also successfully applied for the removal of boron from seawater in the presence of high concentration of foreigner ions. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 567, pp. 96-100 
article DOI  
Abstract: Copper phthalocyanine molecules have grown at room temperature under ultra high vacuum on hydrogen-terminated surface Si(100)2 x 1-H. Chemical and electronic properties of the interface were investigated by ultraviolet and X-ray photoemission spectroscopy (UPS, XPS). Results: Results indicated the existence of an interfacial dipole of 0.36 +/- 0.05 eV and a band bending of 0.40 +/- 0.05 eV. These were evidenced by shifts of XPS core levels and change of the vacuum level position. During the growth, the work function was found to decrease from 4.5 eV for the substrate to 3.74 eV for the highest coverage (40 monolayers). This band bending was also due to the shift of the highest occupied molecular orbital. The interfacial dipole was correlated to a rearrangement of molecules on the surface. An energy level diagram of the interface was deduced from a combination of the XPS and UPS results. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 183(0), pp. 156-161 
article URL 
Abstract: Abstract It is shown that treatment of MIL-53(Al) (Al(OH)BDC·H2O, BDC = 1,4-benzene dicarboxylate) under reflux in water results in a progressive transformation of the solid into a new well crystallized phase. After reflux for 10 h or more the new phase is obtained in a pure form and its XRD pattern was indexed in a monoclinic system with the following cell parameters: a = 19.47 Å, b = 8.98 Å, c = 6.60 Å, β = 107.7°. Characterization of the obtained solid by TGA, FT-IR, NMR, TEM and XRD has revealed that its composition is [0.8Al(OH)BDC·0.2H2BDC] + 0.2γ-AlO(OH). Formation of this material indicates that under reflux in water a partial hydrolysis of the MOF network occurs producing H2BDC molecules (occluded in the pores) and γ-AlO(OH) species. The latter is shown to form a thick shell (100-200 nm) consisting of strongly crumpled sheets of 3 nm of thickness. Formation of γ-AlO(OH) under reflux in water allows to use such treatment as an easy way to modify the surface properties of MIL-53(Al). We showed that treatment of MIL-53(Al) under reflux in water for a short time (&lt;1 h) yields a thin layer of γ-AlO(OH) on the surface of the particles while only slightly decreasing their pore volume (from 0.57 to 0.50 cm3/g). Such surface modification of MIL-53(Al) might be useful from two points of view. First, it creates a strongly hydrophilic layer on the surface of material and may thus facilitate its shaping. Second, the OH groups of γ-AlO(OH) surface layer may be used as anchoring sites for functionalization of MIL-53(Al) particles.

Vol. 190(0), pp. 109-116 
article URL 
Abstract: The thermal conductivity of mesoporous silica particles prepared as fine powder and heat treated between 150 and 700 °C has been studied. Mesostructured silica particles of 30 nm diameter were synthesized through a derived sol–gel method in the presence of a cationic surfactant. The thermal conductivity was found to be ranged from 0.03 to 0.08 Wm−1K−1 according to treatment and packing while the density, the porous volume and the specific surface area of materials varied between 350 and 700 kg/m3, 0.01 and 1.21 cm3/g, and 10 and 420 m2/g, respectively. The analyses carried-out with X-ray diffraction, scanning electron microscopy, transmission electron microscopy, manometric adsorption/desorption of nitrogen, Fourier transform infrared spectrometry and solid-state nuclear magnetic resonance of 29Si nucleus revealed that the thermal conductivity was modified in agreement with the structural changes subsequent to dehydration, decomposition of organic matter, loss of hydroxyl groups and sintering of silica particles.

Vol. 17(1), pp. 219-226 
article DOI  
Abstract: Chemical Looping Combustion is a promising technology for clean power generation with integrated CO2 capture. In this process the oxygen required for combustion is provided by a metal oxide. This work deals with the development of an experimental procedure to study performances of an oxygen carrier during oxidation/reduction cycles and the influence of the oxidation step on its behaviour. Tests were performed in a laboratory fixed bed reactor, with NiO/NiAl2O4, a promising oxygen carrier, and CO as fuel. Two different protocols of oxidation were studied. Results reveal that the oxidation step conditions can change the performances of the oxygen carrier. A significant decrease in total reduction capacity was observed using the regeneration step at high temperature due to structural changes in particles. SEM analysis reveals that particle surface contains different crystallites according to this procedure. With the second procedure ( oxidation in temperature ramp), nickel is partially agglomerated.

Vol. 4(52), pp. 27242-27249 
article DOI  
Abstract: The continuous gas-solid (environmentally-friendly) chlorination of deactivated arenes using trichloroisocyanuric acid (TCCA, C3N3O3Cl3) as a chlorination agent was chosen to compare the catalytic performances of various MFI-type catalysts in a reaction demanding a strong acidity. Mass transfer limitations were also evaluated by reacting either chloro-or nitrobenzene through a ZSM-5 zeolite porous network having different crystal sizes and morphologies. Whereas, the reaction rate was completely controlled by internal diffusion in 10-15 mu m-sized big ZSM-5 zeolite crystals (Weisz modulus, phi(big) crystals similar to 10), the impact of internal diffusion could be ruled out for ZSM-5 nanocrystals (200-400 nm) and in stacked ZSM-5 nanosheets (thickness 2 nm). Based on reactivity differences in arene halogenation between the two nano-sized ZSM-5 zeolites, we were able to estimate the quantity of mild acidic silanol groups in ZSM-5 nanosheets to roughly 1/3 of the total amount of BrOnsted acid sites.

Vol. 16(28), pp. 14722-14729 
article URL 
Abstract: C60 fullerene assemblies on surfaces have attracted considerable attention because of their remarkable electronic properties. Now because of the competition between the molecules-substrate and the molecule-molecule interactions, an ordered C60 array is rather difficult to obtain on silicon surfaces. Here we present density functional theory simulations on C60 molecules deposited on a TBB (1,3,5-tri(1[prime or minute]-bromophenyl)benzene) monolayer lying on the Si(111)-boron surface (denoted SiB). The C60 molecules are located in the nanopores formed by the TBB network. Adsorption energy calculations show that the SiB surface governs the C60 vertical position, whereas the TBB network imposes the C60 lateral position, and stabilizes the molecule as well. The low charge density between the C60 and the SiB substrate on one hand, and on the other hand between the C60 and the TBB molecules, indicates that no covalent bond is formed between the C60 and its environment. However, according to charge density differences, a drastic charge reorganisation takes place between the Si adatoms and the C60 molecule, but also between the C60 and the surrounding TBB molecules. Finally, calculations show that a C60 array sandwiched between two TBB molecular layers is stable, which opens up the way to the growth of 3D supramolecular networks.

Vol. 16(24), pp. 12164-12171 
article DOI  
Abstract: In the framework of the Density Functional Theory (DFT-D), we investigate the phthalocyanine (H2Pc) molecule adsorption on SiC(0001) 3 x 3 and Si(111)root 3 x root 3R30 degrees-B (SiB) surfaces, and particularly compare the involved molecular adsorptions. In the H2Pc-SiC(0001) 3 x 3 system, the molecular adsorption can be ascribed to a [10+2] cycloaddition. The H2Pc-SiB system is considered in three cases: defectless SiB surface (denoted SiB-0D) and SiB surfaces presenting one or two boron defects (denoted SiB-1D and SiB-2D respectively). The SiB-0D surface is passivated by a charge transfer from the Si adatoms to the boron atoms and therefore no chemical bond between the molecule and the substrate is observed. A similar molecular adsorption as already evidenced in the H2Pc-SiC(0001) 3 x 3 system is involved in the SiB-2D case. In the case of the SiB-1D surface, two Si-N bonds (Si1-N1 and Si-2-N-2) are observed. One of them, Si1-N1, is nearly similar to that found in the H2Pc-SiB-D-2 system, but the Si-2-N-2 bond is unexpected. The Bader charge analysis suggests that, in the presence of the H2Pc molecule, the boron atoms behave like an electron reservoir whose availability varies following the involved molecular adsorption process. In the SiB-1D case, charges are transferred from the substrate to the molecule, allowing the Si-2-N-2 bond formation. Such a kind of molecular adsorption, not yet observed, could be designed by "assisted pseudo cycloaddition''.

Vol. 151, pp. 271-277 
article DOI  
Abstract: Aqueous solutions of condensed tannins were submitted to hydrothermal carbonization (HTC) in a stainless steel autoclave, and the kinetics of hydrothermal carbon formation was investigated by changing several parameters: amount of tannin (0.5; 1.0; 1.5; 2.0 g in 16 mL of water), HTC temperature (130, 160, 180 and 200 degrees C) and reaction times (from 1 to 720 h). The morphology and the structure of the tannin-based hydrothermal carbons were studied by TEM, krypton adsorption at - 196 degrees C and helium pycnometry. These materials presented agglomerated spherical particles, having surface areas ranging from 0.6 to 10.0 m(2) g(-1). The chemical composition of the hydrothermal carbons was found to be constant and independent of reaction time. HTC kinetics of tannin were determined and shown to correspond to first-order reaction. Temperature-dependent measurements led to an activation energy of 91 kJ mol(-1) for hydrothermal conversion of tannin into carbonaceous microspheres separable by centrifugation.

article DOI  
Abstract: We report for the first time the formation of spherical and branched structures when polymerizing maleic anhydride under very low power with pulsed plasma polymerization. A factorial experimental design evidenced duty cycle, frequency and their interactions as decisive factors for the formation and growth of these structures. A mechanism involving the decoupling of deposition (nucleation) and diffusion rates of active species was proposed to relate structure formation to processing parameters. While differences in surface chemistry were not detectable by surface spectroscopy (PM-IRRAS, XPS), AFM force measurements on a carefully designed sample evidenced differences in adhesion and thus surface chemistry between the different film morphologies.

Vol. 409, pp. 330-341 
article DOI  
Abstract: Crystalline cobalt phosphides were synthesized by using three different, low oxidation-state organometallic clusters as precursors, [Co-4(CO)(10)(mu-dppa)], [Co-4(CO)(10)(mu(4)-PPh)(2)] and [Co-4(CO)(8)(mu-dppa)(2)] (dppa = Ph2PNHPPh2), which are characterized by Co/P ratios of 2:1, 2:1 and 1:1, respectively. Depending on their Co/P ratio, these clusters are suitable single-source precursors to form CoP and Co2P without the need to add any other reagent or surfactant. The thermal behavior of these three clusters was investigated under different conditions. The results show how their Co/P ratios, the nature of the atmosphere used for their thermal activation and the temperature control the nature and composition of the resulting phases.

Influence of surface fibre properties and textural organization of a pyrocarbon interphase on the interfacial shear stress of SiC/SiC minicomposites reinforced with Hi-Nicalon S and Tyranno SA3 fibres 2014 Journal of the European Ceramic Society
Vol. 34(2), pp. 179-188 
article DOI  
Abstract: SiC/SiC composites reinforced with 3rd generation SiC fibres (Hi-Nicalon S and Tyranno SA3) are attractive for nuclear applications. The mechanical properties of SiC/SiC minicomposites were studied in relation with the nature of fibres and the textural organization of the pyrocarbon interphase. Two different experimental mechanical procedures were used: the push-out test and the tensile mechanical test. The experimental results demonstrate that the interfacial shear stress is higher for a minicomposite reinforced with Tyranno SA3 fibres. It is also shown that the interfacial shear stress depends on the texture of the carbon interphase. Highly anisotropic pyrocarbon interphase increases the interfacial shear stress. To our knowledge it is the first time that the influence of pyrocarbon texture is observed on SiC/SiC composites using Hi-Nicalon S and Tyranno SA3 fibres. It is also demonstrated that push-out tests are more appropriated than tensile tests to highlight differences of interfacial shear stress measurements. (C) 2013 Elsevier Ltd. All rights reserved.

Vol. 550, pp. 177-183

Abstract: In sol-gel polymerization of alkoxysilane precursors, base catalysts are usually employed to introduce textural properties. Herein, we show the feasibility and interest of a photobase-catalyzed sol-gel reaction to afford silicate films. Our inorganic polymerization is solvent-free, single-step and UV activatable with a mixture of alpha-aminoacetophenone (photobase generator), benzophenone (photosensitizer) and triphenylphosphine (oxygen scavenger). To date, the present tricomponent photolatent system generating N-alkyl morpholine tertiary amines represents one of the most efficient photobase generators reported so far in sol-gel chemistry. A combination of spectroscopic and electronmicroscopy techniques enabled to investigate the fundamental chemistry underlying alkoxysilane photopolymerization: reaction mechanism, hydrolysis kinetics and siloxane microstructure. Systematic comparison with a photoacid-catalyzed process revealed also the impact of the photocatalyst nature on film texture, morphology and optical properties. (C) 2013 Elsevier B.V.

Vol. 118(11), pp. 3207-3217 
article DOI  
Abstract: Supramolecular assembly allows for enhanced control of bulk material properties through the fine modulation of intermolecular interactions. We present a comprehensive study of a cross-linkable amphiphilic wedge molecule based on a sulfonated trialkoxybenzene with a sodium counterion that forms liquid crystalline (LC) phases with ionic nanochannel structures. This compound exhibits drastic structural changes as a function of relative humidity (RH). Our combined structural, dynamical, and transport studies reveal deep and novel information on the coupling of water and wedge molecule transport to structural motifs, including the significant influence of domain boundaries within the material. Over a range of RH values, we employ Na-23 solid-state NMR on the counterions to complement detailed structural studies by grazing-incidence small-angle X-ray scattering. RH-dependent pulsed-field-gradient (PFG) NMR diffusion studies on both water and the wedge amphiphiles show multiple components, corresponding to species diffusing within LC domains as well as in the domain boundaries that compose 10% of the material. The rich transport and dynamical behaviors described here represent an important window into the world of supramolecular soft materials, carrying implications for optimization of these materials in many venues. Cubic phases present at high RH show fast transport of water (2 X 10(-10) m(2)/s), competitive with that observed in benchmark polymeric ion conductors. Understanding the self-assembly of these supramolecular building blocks shows promise for generating cross-linked membranes with fast ion conduction for applications such as next-generation batteries.

Chouchene, A., Jeguirim, M. and Trouve, G. Biosorption performance, combustion behavior, and leaching characteristics of olive solid waste during the removal of copper and nickel from aqueous solutions 2014 Clean Technologies and Environmental Policy
Vol. 16(5), pp. 979-986 
article DOI  
Abstract: Several researchers have proved that agricultural by-products constitute good adsorbents for removing heavy metals from aqueous solution. However, few investigations have identified efficient strategies for the adsorbent's regeneration. Hence, a global methodology for the removal of copper and nickel metals from wastewater including metal biosorption, thermal treatment and residual ash landfill is proposed. In order to validate this strategy, olive solid waste (OSW), provided by an olive oil mill from Tunisia, were used to remove copper and nickel on batch experiments. Copper and nickel were adsorbed on a monolayer of OSW surface with maximal adsorption capacity (q (max)) of 3.6 and 1.7 mg g(-1), respectively. Contaminated OSW with copper and nickel were combusted at 850 A degrees C in an electrical furnace. About 96 % of each metal was recovered in residual ashes that present a good secondary raw material for copper and nickel production. Low leaching transfers (a parts per thousand currency sign4 %) were observed for copper and nickel from residual ashes leading to the possibility to be landfilled. Therefore, the suggested process can be used as an alternative to the classical technologies for effluent decontamination.

Abstract: Understanding the adsorption of water in metal organic frameworks (MOF), and particularly in soft porous crystals, is a crucial prerequisite before considering MOFs for industrial applications. We report here a joint experimental and theoretical study on the behavior of a gallium-based breathing MOF, Ga-MIL-53, upon water adsorption. By looking at the energetics and thermodynamics of Ga-MIL-53, we demonstrate why it behaves differently from its sibling Al-MIL-53, showing a different phase at room temperature (a nonporous phase) and the presence of a hydrated narrow-pore structure at gas saturation pressure. Moreover, we present a complete water vapor pressure vs temperature phase diagram of Ga-MIL-53 upon water adsorption.

Abstract: This study focuses on changes in the oxidn. state of silver and in the cryst. phase of TiO2 occurring during the photochromic transitions of amorphous nanocomposite mesoporous Ag:TiO2 films exposed to UV and visible laser light. The chem. and phase transformations have been investigated by UV-visible spectroscopy, XPS, transmission electron microscopy, high-angle annular dark field scanning transmission electron microscopy, and high-resoln. transmission electron microscopy. The results bring to the fore the presence of both silver nanoparticles in face-centered cubic and hexagonal cryst. phases during the photochromic transitions and a large amt. of oxidized silver nanoparticles after visible light exposure, along with nucleation of some TiO2 crystals despite the very low intensity used.

Vol. 263(0), pp. 130-140 
article URL 
Abstract: Abstract The development of advanced and safe electrochemical supercapacitors or hybrid supercapacitors combining a battery electrode material such as graphite and a porous carbon electrode implies the use of new electrolytes containing a tetra-alkylammonium or lithium salt dissolved preferentially in a safe and environmentally friendly solvent such as alkylcarbonates. In those systems, the carbon porosity of the activated carbon electrode controls the electrochemical behavior of the whole device. In this work, it is demonstrated that electrolytes containing highly polarizing ions such as Li+ dissolved in polar solvents such as alkylcarbonates do not completely loss their solvation shell at the opposite of what is observed for poorly solvated cations like TEABF4. As a consequence, the optimal carbon pore size for obtaining the largest energy density, while keeping a high power density, is wider when strongly solvated cations, like Li+ are used than for conventional organic electrolytes using acetonitrile as solvent and TEA+ as salt cations. TEA+ cations are easily desolvated and hence are able to penetrate in small pores matching the dimensions of bare ions. The dissimilarity of behavior of alkylcarbonates and acetonitrile based electrolytes highlights the importance of ion-solvent interactions when searching the optimal porous texture for the electrode material.

Vol. 2, pp. 1-8 
article DOI  
Abstract: In view of their technological impact in materials chemistry, a simplified and more efficient synthetic route to mesoporous films is highly sought. We report, herein, a smart UV-mediated approach coupling in a one-stage process sol-gel photopolymerization and photoinduced template decomposition/ablation to making mesoporous silica films. Performed at room temperature with a solvent-free solution of silicate precursor and amphiphilic poly(ethylene oxide)-poly(propylene oxide)- poly(ethylene oxide) block copolymer, the synthesis relies on photoacid generation to induce the fast formation (≈10 min) of mesostructured silica/surfactant domains. Continuation of UV exposure for three additional hours enables subsequent and complete photodegradation of the polyether copolymer, resulting in ordered or disordered mesoporous silica film. One of the most attractive features is that the one-step procedure relies on a continuous illumination provided by the same conventional mediumpressure Hg-Xe arc lamp equipped with a 254 nm reflector to enhance the emission of energetic photons <300 nm. In addition to X-ray diffraction and transmission electron microscopy, time-resolved Fourier transform infrared spectroscopy has proved to be a powerful in situ technique to probe the different chemical transformations accompanying irradiation. Photocalcination strengthens the inorganic network, while allowing to preserve a higher fraction of residual silanol groups compared with thermal calcination. A polyether chain degradation mechanism based on oxygen reactive species-mediated photo-oxidation is proposed

Abstract: Recent research has shown that silica/surfactant self-assembly combined with photoacid-catalyzed sol?gel polymerization can direct the formation of disordered mesoporous silica films. Using only a mixture of photoacid generator (PAG), amphiphilic surfactant (PEO-b-PPO-b-PEO), and methoxy oligomeric precursor, this original UV-driven method is fast and obviates the need of sol preparation and volatile compounds. Here, we report a rational basis to promote a disorder-to-order transition through the control of relative humidity (RH) and irradiance. Above a threshold RH of 35%, a long-range organization is promoted by greater interactions between the water-enriched silica phase and the PEO block. Alternatively, mesophase rearrangement and ordering are achieved by decreasing the irradiance below a limiting value (150 mW/cm2) so as to minimize the condensation rate. These two strategies show that the fundamental driving force for the creation of well-ordered hybrid mesostructures can be described both on thermodynamic and kinetic grounds. Subsequently, these optimized reaction conditions are exploited to tailor the final mesophase (hexagonal, lamellar, cubic) at different template/inorganic ratios. In a last part, the photoinduced mesostructuration mechanism is elucidated for model lamellar films using X-ray diffraction and Fourier transform infrared spectroscopy.

Abstract: The preparation of a heterogeneous Pd catalyst supported on carbon-coated magnetic nanoparticles (NPs) bearing 4-(diphenylphosphinomethyl)phenyl groups is discussed. These NPs were initially prepared by chemical vapour deposition (CVD) of carbon on preformed Co NPs; however, the particles prepared in one step by reducing flame synthesis were more appropriate for functionalization. The Pd catalyst was then prepared by three simple steps. We show that Suzuki-Miyaura couplings can be efficiently performed in the presence of very low amounts of supported Pd, usually 50 μequiv. Finally, the Pd leaching was very low: in most cases only 1 μequiv. of Pd is found in the reaction medium (which amounts to less than 1 ppm of the product). Compared to other catalysts supported on magnetic particles, this catalyst is very simple to prepare even in large quantities and is easy to recover completely owing to the high magnetic saturation of the Co nucleus. To the best of our knowledge, it is the simplest and the most-active Pd catalyst supported on carbon-coated Co nanoparticles for Suzuki-Miyaura reactions. The reusability of the catalyst was also ascertained.

Vol. 281, pp. 8-17 
article DOI  
Abstract: In this work, efficiency of initiation of the photopolymerization in ionic liquids (ILs) by four Type I photoinitiators (Pls) was investigated. The influence of the ILs on the initiation process was determined by investigation of the polymerization kinetics and by spectroscopic and photolysis studies. The polymerization initiated by three of the tested Pls proceeded faster in ionic liquids, whereas the efficiency of the photoinitiator depended strongly on the structure of the ionic liquid. In one case, (2-methyl-4 '(methylthio)-2-morpholinopropiophenone), there was a significant reduction in the reaction rate, which resulted from a drastic decrease in the quantum yield of photolysis of this photoinitiator in ionic liquids. The results obtained suggest that for every composition containing an ionic liquid, the photoinitiator should be matched individually. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 6(1), pp. 328-338 
article DOI  
Abstract: Solids composed of TiO2 nano-crystallites (10-40wt%) dispersed in an SBA-15 matrix were synthesised and used as hydrodesulfurisation (HDS) active-phase supports. Well-dispersed polymolybdate species were detected by Raman spectroscopy on all the CoMo-based oxidic precursors. Undesirable bulk CoMoO4 mixed oxide was also detected on the surface of low-TiO2-content materials, which suggests the enhancement of the Mo oxidic species dispersion as a result of the presence of TiO2. After activation under H-2/H2S, the obtained catalysts were tested in the HDS of thiophene. An optimum conversion was observed for the catalyst supported on the solid that contained 20wt% TiO2, which outperformed the homologous samples supported on TiO2 and SBA-15. This clearly highlights the beneficial effect of using such nano-TiO2-SBA-15 composite supports, in which SBA-15 confers adequate textural properties to the system, and the active phase benefits from the dispersive effect of TiO2.

Vol. 77, pp. 688-704 
article DOI  
Abstract: The thermal exfoliation of graphite fluoride was investigated using two starting materials: fluorinated HOPG and powdered room temperature graphite fluoride (RTGF) post-treated in pure F-2 gas in order to adjust the relative contents of intercalated species, the carbon hybridization and the C-F bonding. Firstly, the thermal exfoliation of HOPG sample (of composition CF0.57) at the nanoscale is highlighted using scanning tunneling microscopy (STM). Such process involves a defluorination, which is accelerated by disruption of the graphene sheets. Similar breaking occurs during the exfoliation of post-treated RTGF and evolves CF4 and C2F6 gases. Moreover, the exfoliation using a thermal shock is assisted by the fast deintercalation of the catalyst species in the region where the covalence of the C-F bonds is weakened. In such way, exfoliation occurs with the quasi-total defluorination. (C) 2014 Elsevier Ltd. All rights reserved.

Vol. 562, pp. 530-537 
article DOI  
Abstract: A neutral heteroleptic iridium(III) complex bis(1-phenylisoquinoline) (dibenzoylmethane)iridium(III) Ir(piq)2(dbm) bearing a dibenzoylmethane (dbm) moiety as the ancillary ligand has been designed and investigated as an emitter in phosphorescent organic light emitting devices (PhOLEDs). To date, the family of dbm based complexes has only been scarcely investigated in OLEDs and only one complex of this family has been tested in electroluminescent devices. Interestingly, pure red devices were obtained with this emitter. PhOLEDswere fabricated at different dopant concentrations and the best device performances were obtained in the device with 8wt.% dopant concentration. Ir(piq)2(dbm) was characterized by UV-visible absorption and photoluminescence spectroscopy, cyclic voltammetry and theoretical calculations were also performed to support our experimental results.

Abstract: A series of blue fluorescent Zn (II) tetradentate Schiff base complexes has been designed and synthesized for applications in organic light-emitting diodes. The five complexes were investigated as dopant materials or as single emitters of multilayered p-i OLEDs. White OLEDs were achieved using these compounds as dopants of 4,4′,4″-tris(N-carbazolyl)triphenylamine and best devices exhibited a high quality white-light emission with remarkable CIE (Commission Internationale de l'Eclairage) coordinates (0.33, 0.34). When used as single emitters, sky-blue and blue electroluminescent devices were prepared, except with one complex that gave yellow OLEDs. Optical properties of these complexes were examined by UV-visible absorption and luminescence spectroscopy. Their electrochemical properties are also reported. These results open the route to the development of cost-effective complexes for white organic light-emitting devices applications.

Abstract: Abstract Two heteroleptic iridium complexes have been designed with 1-methyl-3-propyl-5-(2,4,5-trifluorophenyl)-1H-1,2,4-triazole as the cyclometalated ligand and acetylacetone (acac) or dibenzoylmethane (dbm) as the ancillary ligands. Interestingly, when tested as emitters for phosphorescent OLEDs (PhOLEDs), these two isostructural complexes that only have varying ancillary ligands exhibited completely different behaviors in devices. Notably, highly efficient PhOLEDs were only obtained with the complex bearing dbm as the ancillary ligand. To get a deeper insight in this unexpected behavior, TD-DFT calculations were carried out. The optical properties of the two complexes (UV-vis absorption and photoluminescence) and their electrochemical behaviors were also studied.

Abstract: A mordenite membrane was prepared and surface characterizations were performed on the synthesized mordenite (as powder form). The surface charge remained constant when mordenite powder was in contact with the studied solutions. A pore diameter of 5.8 x 10(-9) m was estimated. Filtration tests of single salt-water solutions (NaCl, NaF, and Na2SO4) were carried with the mordenite membrane. No rejection was observed. After an alkaline treatment, the rejections were observed: NaF = Na2SO4 = 5-6%, while NaCl = 0%. New filtration tests of mixed salt-water solutions were carried out (Na2SO4 + NaCl and Na2SO4 + NaF). The sulfate ion was retained by a majority (up to 16%) whatever the halide ion in solution. The rejection rate of sulfate ion in mixtures decreases with the applied pressure, which actually cannot be explained (no observable polarization layer effect). A preferential transport is observed for chloride ions and the rejection rate of the fluoride ions remained constant. A numerical modeling (Nernst-Planck approach) was used to understand the modifications due to the alkaline treatment. A significant modification of dielectric effects is observed, which completely modified the filtration properties of the Na-mordenite membrane.

Vol. 62, pp. 209-215 
article DOI  
Abstract: Combustion tests of five date palm Tunisian residues, namely: Date Palm Leaflets (DPL), Date Palm Rachis (DPR), Date Palm Trunk (DPT), Date Stones (DS) and Fruit-stalk Prunings (FP), were performed in a laboratory scale furnace. Gaseous emissions such as CO2, CO, VOC, NOx and SO2, were analysed at 600 degrees C under 30-60 NL/h flow rate. Obtained results were compared with sawdust combustion behaviour in order to select the most convenient biofuel for an application in domestic boiler installations. Combustion tests show that ignition delay and combustion time reaction are independent of the date palm residue. However, gaseous products emission rates and factors are correlated to the sample characteristics such as carbon, nitrogen and sulphur contents as well as fixed carbon and volatile matters contents. In order to optimize date palm residues combustion by decreasing unburnt gaseous emissions, special attention should be given to the design of the secondary air supply. (C) 2013 Elsevier Ltd.

Abstract: In this paper, we propose to review the ways to produce, through photopolymerization, interpenetrating polymer networks (IPN) based, e.g., on acrylate/epoxide or acrylate/vinylether blends and to outline the recent developments that allows a one-step procedure (concomitant radical/cationic polymerization), under air or in laminate, under various irradiation conditions (UV/visible/near IR; high/low intensity sources; monochromatic/polychromatic sources; household lamps/laser diodes/Light Emitting Diodes (LEDs)). The paper illustrates the encountered mechanisms and the polymerization profiles. A short survey on the available monomer systems and some brief examples of the attained final properties of the IPNs is also provided. © 2014 by the authors.

Vol. 77(6), pp. 1030-1036 
article DOI  
Abstract: Fluoropolymers have attracted a lot of attention in the past 20 years mainly due to their hydrophobic properties. Unfortunately, they have also shown some stability issues mainly in hot water due to the easy disorganization of the fluorine chains. In this paper Confocal Raman Microscopy (CRM) has been used as an indirect probe to optimize the fluoroacrylate content in an acrylic photocurable resin in order to reduce the effect of hot water. Advancing and receding contact angles have also been measured to characterize the surface repellence both before and after immersion in hot water. Results show that despite an improvement of the stability of the fluoroacrylate coating with a careful selection of the concentration range, water still has a negative effect on the surface properties of the coating. This effect can be partly counterbalanced by successive thermal annealings at 100 degrees C which help to stabilize the hydrophobicity of the coating. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 16, pp. 3079-3088 
article  
Abstract: Carbon porous materials with a periodically ordered pore structure, controlled pore size and geometry and high thermal stability are synthesized using self-assembly of environmentally friendly phloroglucinol/ glyoxylic acid precursors with an amphiphilic triblock copolymer template. Glyoxylic acid, a plant-derived compound, is used for the first time as a substituent of carcinogen formaldehyde usually employed in such a synthesis. Thanks to the double functionality, i.e., aldehyde and carboxylic acid, glyoxylic acid plays not only the role of a cross-linker for the formation of the resin but also the role of a catalyst by creation of H-bonding or specific reactions between the precursors. Hence, no extra catalyst such as strong acids (HCl) or bases (NaOH) is any longer required. Carbon films and powders were successfully prepared with high surface areas (up to 800 m2 g−1), high porous volume (up to 1 cm3 g−1), tunable pore size (0.6 nm to 7 nm) and various pore architectures (hexagonal, cubic, and ink-bottle) by tuning the precursor ratio and by applying different manufacturing engineering strategies. Insights on the synthesis mechanism of the phenolic resin and carbon mesostructures were obtained using several analysis techniques, i.e., nuclear magnetic resonance (13C NMR) and FTIR spectroscopy, temperature programmed desorption coupled with mass spectrometry (TPD-MS) and thermo-gravimetric analysis (TGA).

Vol. 67, pp. 260-272 
article DOI  
Abstract: A novel synthesis pathway is proposed in this work to prepare NiCo nanoalloy embedded in highly ordered porous carbons via a soft-template approach. This involves the multicomponent co-assembly of environmental friendly carbon precursors (phloroglucinol and glyoxal), amphiphilic copolymer Pluronic F127 as structure directing agent followed by metal precursor salts incorporation. This synthesis affords a good control of the alloy quantity, composition and particle size in the carbon matrix. The influence of the metal loading in the NiCo alloy and of two chelating agents, i.e., citric acid and oxalic acid on the physical-chemical characteristics of carbon NiCo materials was investigated. In the absence of chelating agents, the carbon NiCo hybrid materials have a 2-D hexagonally arranged pore structure, high surface area and porous volume. The NiCo nanoparticles are homogeneously distributed in the carbon network and they exhibit sizes between 30 and 40 nm depending on the Ni/Co ratio. The use of chelating agents allows downsizing the particle size to 15 nm and the modification of the hexagonally carbon structure into a worm-like one. The advantage of the present synthesized hybrids lays in the use of less expensive 3d transition metals than noble elements that may provide comparable effect on hydrogen sorption properties.

Vol. 44Journal of Applied Electrochemistry, pp. 123-132 
article URL 
Abstract: The synthesis of lambda-manganese oxide (λ-MnO2) with a developed porosity and an ordered and interconnected pore structure used as supercapacitor electrode is reported for the first time in the present study. A spinel-type LiMn2O4 material was first prepared by hard-templating pathway using KIT-6 mesoporous silica as a template and metal nitrates as precursors, which was subsequently acid treated leading to λ-MnO2 material. The materials exhibit high surface area (up to 150 m2 g−1), defined pore size distribution with three-dimensional interconnected pores, and crystalline pore walls. The material textural properties as well as the morphologies vary considerably with the synthetic conditions. The as-synthesized porous λ-MnO2 materials exhibit a noticeably better performance (120 F g−1) at high constant currents (1 A g−1) than commercial derived λ-MnO2 (11 F g−1). The extended surface area and the porous and three-dimensional interconnected structures along with the specific morphology significantly enhance the lithium diffusion through the particles and allow for a more effective use of this pseudocapacitive material as an electrode in supercapacitor.

Giljean, S., Bigerelle, M. and Anselme, K. Roughness Statistical Influence on Cell Adhesion Using Profilometry and Multiscale Analysis 2014 Scanning
Vol. 36(1), pp. 2-10 
article DOI  
Abstract: In this study, two series of 11 samples of TiAl6V4 titanium alloy and 316L stainless steel have been polished in an isotropic manner at different levels in order to quantify the influence of biomaterial roughness on cell behavior. Topography was measured by a tactile profilometer and a multiscale analysis has been carried out. Human osteoblasts have been cultured on those samples. It appears that roughness has no reproducible effect on the cell behavior except an influence on cell orientation on the wider grooves. As a conclusion, biomaterial surface damage, in the roughness range between R-a = 0.01 and 0.1 m, has no influence on cell-adhesion mechanisms when roughness is isotropic and groove width is inferior to a critical value.

Haidara, H. Wetting-mediated collective tubulation and pearling in confined vesicular drops of DDAB solutions 2014 Soft Matter
Vol. 10, pp. 9060-9469 
article DOI  
Abstract: Whether driven by external mechanical stresses (shear flow) or induced by membrane-active peptides and/or proteins, the collective growth of tubules in membranous fluids has seldom been reported. The pearling destabilization of these membranous tubules which requires an activation of the shape distortion, often induced by optical tweezers, membrane-active biomolecules or an electrical field, has also rarely been observed under mild experimental conditions. Here we report such events of collective tubulation and pearling destabilization in sessile drops of a didodecyl-dimethylammonium bromide (DDAB) vesicular solution that are confined by a surrounding oil medium. Based on the wetting dynamics and the features of the tubulation process, we show that the growth of the tubules here relies on a mechanism of "pinning-induced pulling" from the retracting drop, rather than the classical hydrodynamic fingering instability. We show that the whole tubulation process is driven by a strong coupling between the bulk properties of the ternary (DAAB/water/oil) system and the dynamics of wetting. Finally, we discuss the pearling destabilization of these tubules under vanishing static interface tension and quite mild tensile force arising from their pulling. We show that under those mild conditions, shape disturbances readily grow, either as pearling waves moving toward the drop-reservoir or as Rayleigh-type peristaltic modulations. Besides revealing singular non-Rayleigh pearling modes, this work also brings new insights into the flow dynamics in membranous tubules anchored to an infinite reservoir.

Abstract: Abstract The electrochemical and structural characterization of thermally grown oxides formed on nickel based alloys (type Inconel 600 and 690) at 350 °C and during different time was performed by impedance measurements and near field microscopy combining atomic force microscopy (AFM) and scanning Kelvin probe force microscopy (SKPFM). The impedance results allow discussing the influence of the oxidation time on the capacitance and the resistance of the oxide films. The results obtained by near field microscopy technique show that the film formed during low oxidation time has a small grain size and also a small surface roughness. The values of grain sizes determined in both cases along x- and y-axis are practically the same indicating a spherical shape of oxide grains and are slightly different between oxides formed on type inconel 600 and 690.

Abstract: Industrial activity generates huge amounts of waste, whose storage can lead to serious problems of groundwater pollution by infiltration of landfill leachates. Geomaterials used as water barriers may be a solution to this problem. This work is devoted to the elaboration of new geomaterials based on Algerian clay, activated carbon, cement, and polymer for containment of stored waste and the study of their performances towards inorganic pollutants. Thus we elaborated a set of three geomaterials GM1, GM2, and GM3 with various clay and activated carbon contents and whose polymer and cement compositions are maintained constant. The higher clay content (80%) was used in preparing GM1.The retention properties towards lead were assessed by the adsorption isotherms of geomaterials and their minerals constituents. The study of lead adsorption isotherms on geomaterials showed mainly that GM1, with the highest clay and lowest activated carbon contents and with the highest specific surface area, is very effective for trapping lead. Moreover, its adsorption capacity is pH-dependant; the highest Pb2+ amount adsorbed is obtained for pH12. On the other hand, it has been shown that the retention of lead is a result of the components contribution: clay, activated carbonm and cement.

Vol. 30(31), pp. 9378-9383 
article DOI  
Abstract: In this work, we discuss quantitatively two basic relations describing the wetting behavior of microtopographically patterned substrates. Each of them contains scale invariant topographical parameters that can be easily expressed onto substrates decorated with specifically designed micropillars. The first relation discussed in this paper describes the contact angle hysteresis of water droplets in the Cassie-Baxter regime. It is shown that the energy at the origin of the hysteresis, that has to be overcome for moving the triple line, can be invariantly expressed for hexagonal pillars by varying the pillars width and interpillar distance. Identical contact angle hystereses are thus measured on substrates expressing this scale invariance for pillar widths and interpillar distances ranging from 4 to 128 mu m. The second relation we discuss concerns the faceting of droplets spreading on microtopographically patterned substrates. It is shown in this case that the condition for pinning of the triple line can be fulfilled by simultaneously varying the height of the pillars and the interpillar distance, leading to faceted droplets of similar morphologies. The invariance of these two wetting phenomena resulting from the simultaneous and homothetic variation of topographical parameters is demonstrated for a wide range of pattern dimensions. Our results show that either of those two wetting behaviors can be simply achieved by the proper choice of a dimensionless ratio of topographical length scales.

Vol. 6(9), pp. 4774-4780 
article DOI  
Abstract: The electronic properties of organic semiconductors depend strongly on the nature of the molecules, their conjugation and conformation, their mutual distance and the orientation between adjacent molecules. Variations of intramolecular distances and conformation disturb the conjugation and perturb the delocalization of charges. As a result, the mobility considerably decreases compared to that of a covalently well-organized crystal. Here, we present electrical characterization of large single crystals made of the regioregular octamer of 3-hexyl-thiophene (3HT)(8) using a conductive-atomic force microscope (C-AFM) in air. We find a large anisotropy in the conduction with charge mobility values depending on the crystallographic orientation of the single crystal. The smaller conduction is in the direction of p-p stacking (along the long axis of the single crystal) with a mobility value in the order of 10(-3) cm(2) V-1 s(-1), and the larger one is along the molecular axis (in the direction normal to the single crystal surface) with a mobility value in the order of 0.5 cm(2) V-1 s(-1). The measured current-voltage (I-V) curves showed that along the molecular axis, the current followed an exponential dependence corresponding to an injection mode. In the p-p stacking direction, the current exhibits a space charge limited current (SCLC) behavior, which allows us to estimate the charge carrier mobility.

Abstract: Nous avons étudié le transport, la sorption et la désorption d’un cation organique (bleu de méthylène (BM)), à travers un milieu poreux constitué de particules de sable de quartz chargées négativement. Nous avons examiné l’influence des paramètres, tels que : la force ionique de la solution aqueuse, la vitesse de circulation, le pH de la phase aqueuse, la température du milieu et la nature des cations divalents métalliques présents en solution, sur le transport et le dépot du BM à travers le milieu poreux. Les mesures de la rétention du colorant ont été réalisées en utilisant la technique d’injection-échelon. Les résultats obtenus ont montré une diminution de la quantité de BM adsorbé sur le quartz lorsque le pH de la phase aqueuse diminue de 9,5 a` 4. Une baisse de la quantité de BM adsorbé a été également observée lorsque la force ionique ou le débit augmente. Cependant, l’augmentation de la température a conduit à une augmentation de la quantité de BM adsorbée, ce qui laisse supposer que l’adsorption du BM sur la surface de quartz est de nature endothermique. En pre´sence de cations divalents en solution (Ca2+, Cu2+, Zn2+ et Ba2+), la quantité retenue du colorant dépend de la nature du cation. L’ensemble de ces résultats, montre que l’adsorption du colorant basique est contrôlée par les interactions électrostatiques entre la surface négative du quartz et le polluant organique cationique.

Vol. 458, pp. 187-194 
article DOI  
Abstract: The fine fraction of carbon black (CB) sample N234, initially prepared by the furnace process, was obtained by sieving and it was then dispersed in aqueous medium at various aqueous phase pH. Further, adsorption from water onto this non porous CB particles, of polystyrene-polyethylene oxide (PS-PEO), nonionic diblock copolymers, having molecular weights, M-w = 2000 and M-w = 4000 g/mol, were investigated at ambient temperature. For the bare CB particles, prepared in the absence of copolymers, the TEM micrographs show aggregates and/or agglomerates having sizes depending of the aqueous phase pH, and formed from fused primary particles having sizes in the range 13-17 nm. These aggregates develop intra-porosity that result from their branching shape. The CB bare particles prepared in acidic aqueous dispersion form mostly ellipsoidal agglomerates having sizes exceeding 500 nm. However, by increasing the pH of the medium from pH = 3 to pH = 10, and after drying the CB dispersion, aggregates shaped as "bunch" of grapes and having smaller sizes are observed by TEM. The microelectrophoresis studies of these dispersions indicate that the CB particles are positively and negatively surface charged at pH values, respectively, below and above the Isoelectrical point (IEP) which is about pH similar to 6. Such electrokinetic behavior of the CB aqueous dispersion results from the presence on the CB surface of acidic and basic functional groups. However, upon PS-PEO copolymers adsorption onto CB, reduction in the magnitude of zeta potential, and shift of the Isoelectrical point (IEP) to lower pH values were observed. Such IEP shift is related to the copolymer adsorption on the Stern layer and to the position of the shear plane in the electrical double layer. In addition, the copolymer adsorption was found to reduce the CB particle size achieving a minimum value in water of about 200 nm, resulting in sterically stable CB aqueous dispersions.

Abstract: Abstract A novel nano-GeO2/mesoporous carbon (GeO2/MC) composite material was prepared by in-situ decomposition of germanium ethoxide (Ge(OC2H5)4) infiltrated in a mesoporous carbon (MC) obtained by soft-templating procedure. With GeO2 (&lt;20 nm) homogeneously distributed in the carbon network, the GeO2/MC composite retains 93% of its initial charge capacity after 380 cycles at constant 1 C rate (1500 mA g−1) as electrode material vs. Li and shows high rate capability at variable current rates. A restructuration of the germanium phase into smaller particles during the first cycles is also evidenced. The composite presents a set of advantages such as low GeO2 content, convenient preparation approach and high coulombic efficiency (&gt;99%).

Vol. 292(12), pp. 3095-3102 
article DOI URL 
Abstract: When finally processed to provide the function for which the latex was selected―binding, protecting, finishing―components such as surfactant, costabilizer or initiator become generally useless, not to say detrimental. In this study, we show that miniemulsion photopolymerization provides a suitable method to create latex without the apparent addition of these three compounds. Indeed, UV-driven monomer self-initiation can create initiating radicals without the aid of initiator, the fast in situ photogenerated polymer can hinder Ostwald ripening with the assistance of external costabilizer, and finally, UV-transparent clay can replace conventional surfactant to ensure colloidal stabilization. Each strategy has been developed individually before being combined together to end up with a unique miniemulsion procedure free of initiator, costabilizer and surfactant. Such approach paves the way to a simplified and environmentally improved pathway towards aqueous polymer dispersions.

Vol. 23, pp. 188-192 
article DOI  
Abstract: This paper aims to analyse energy related properties, thermal degradation behaviour and devolatilization kinetics of five Cameroonian biomasses namely, Palm Kernel Shells (PKS), Mesocarp Fibres (PMF), Coffee Husk (CH), Corn Cob (CC) and Peanut Shell (PNS). The thermal degradation was performed using thermogravimetric analysis (TG). Different behaviours related to the presence of chemical constituents such as cellulose, hemicellulose and lignin were obtained. Comparison of the thermal characterization shows that PMF is the most interesting feedstock with the highest heating values and reactivity due to higher volatile content. Decomposition of TG data was analysed by applying diffusion and chemical reaction kinetic models. Obtained results show that biomass pyrolysis is represented by two successive steps. The devolatilization stage characterized by high weight loss rate is well described by diffusion reaction models. In contrast, the char formation stage characterized by low weight loss rate is well described by third order chemical reaction models.

Vol. 92, pp. 1876-1882 
article DOI  
Abstract: Spent coffee grounds (SCG), a processing by-product from the coffee industry, were evaluated as a potential feedstock for preparing agropellets for energy production. Hence, pure SCG and a SCG/sawdust blend were transformed into pellets. The latter thermal and chemical properties such as calorific value, ash content, bulk density, fixed carbon and elemental analysis were obtained. Thermogravimetric analyses were conducted in order to determine pyrolysis kinetics and combustion characteristics in order to study the agropellets performance. The obtained results show that SCG pellets thermal characteristics are in the same order as conventional biomasses such as sawdust. Moreover, blend 50% SCG/50% sawdust reaches the superior NF agropellets standard requirements which are essential to sell this agropellets in the French market. Analysis of the thermal degradation shows that SCG and its blend follow the usual behavior of lignocellulosic materials. Comparison of the combustion characteristics shows a higher reactivity of the blend comparing to pure SCG and sawdust. Such behavior might relate to heterogeneous structure and mutual interaction of the individual components of SCG and sawdust. Pyrolysis kinetics parameters obtained for SCG and SCG/sawdust blend are fairly close agreement with those found in literature for different biomasses. Hence SCG/sawdust may be a promising biofuel for the energy production in industrial applications.

Vol. 5(16), pp. 4747-4755 
article DOI  
Abstract: The cationic photoinitiating abilities of a series of 'push-pull' sulfonium-based photoacid generators (PAGs) have been investigated. In this linear pi-conjugated series, a 4-N,N-diphenylaminostilbene subunit is associated with different types of sulfonium substituents, which are connected to the stilbene moiety either in the 4' position or in the 3' position. This para-to-meta substitution effect leads to a strong increase of the quantum yield for acid generation with a maximum value of ca. 0.5. Such a positioning effect has a strong influence on the efficiency of the S-C bond cleavage. A detailed photolysis mechanism has been proposed. In contrast to commercially available sulfonium salts, these highly reactive pi-conjugated PAGs all exhibit large absorption in the visible range as well as large two-photon absorption cross-sections (delta(max) > 600 GM) in the near-infrared region. As a consequence, efficient one and two-photon polymerization reactions are observed at 405 nm and 800 nm, respectively, using typical monomers such as cyclohexene oxide, n-butyl vinyl ether or SU-8 photoresists. By the fabrication of well resolved two-dimensional microstructures, we finally demonstrate the potential use of these new generation PAGs in the fields of one and two-photon lithography.

Two-photon lithography in visible and NIR ranges using multibranched-based sensitizers for efficient acid generation 2014 Journal of Materials Chemistry C
Vol. 2(35), pp. 7201-7215 
article DOI  
Abstract: We investigated methodically the one- and two-photon absorption properties of a series of multibranched triphenylamine-based chromophores incorporating 4-(methylthio)styryl fragments as external substituents. Some relevant structure property relationships relative to these highly fluorescent compounds have been derived based on emission anisotropy measurements, quantum chemical calculations and the use of the exciton coupling theory. Even though branching effects lead to a cooperative enhancement of the two-photon absorption (2PA), all compounds exhibit relatively low-to-moderate 2PA cross-sections (delta <= 100 GM) in the NIR region. However, the 'so-called' one-photon resonance enhancement effect leads to a remarkable increase of delta by more than one order of magnitude in the visible range. This strong 2PA ability has been associated with an efficient photosensitization of iodonium salt to elaborate a new bicomponent photoacid generator, which is readily two-photon activable at 532 nm. In the visible range, the strong enhancement of the efficiency of the two-photon induced polymerization is clearly demonstrated as compared with that observed in the NIR region.

Abstract: Conventional syntheses of zeolites generally lead to the formation of crystals whose sizes are of the order of several microns which is not detrimental in a large number of industrial applications. However, the capacity and kinetics of pollutant adsorption which are sensitive to diffusion phenomena, surface and porous volume could potentially be improved by the use of nanocrystal or hierarchical zeolites (micro/mesoporous or micro/macroporous). Indeed, zeosil nanosheets hold great potential because of their small size and their high porous volume that promote access of pollutants and increase the adsorption capacity. Herein, silicalite-1 zeosil with a lamellar morphology was successfully synthesized under hydrothermal conditions (110 degrees C, 10 days) using diquaternary ammonium as structuring agent. Compared to the conventional silicalite-1 material, the porous volume of the synthesized nanosheets determined from the N-2 adsorption-desorption isotherms was found to be multiplied by 3.5 (0.62 cm(3) g(-1)) without altering the microporous volume (0.18 cm(3) g(-1)). This result was also confirmed by the increase of the n- hexane adsorption capacity and kinetics in the silicalite-1 nanosheets compared to the conventional silicalite-1. This approach indicates a new way for obtaining zeosil materials of controlled sizes and shapes for molecular decontamination.

Kauffer, F.A., Merlin, C., Balan, L. and Schneider, R. Incidence of the core composition on the stability, the ROS production and the toxicity of CdSe quantum dots 2014 Journal of Hazardous Materials
Vol. 268, pp. 246-255 
article DOI  
Abstract: Mercaptosuccinic acid-capped CdSe and alloyed CdSe(S) QDs were prepared in aqueous solution at 100 and 170 degrees C, respectively. These dots were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV-vis and photoluminescence spectroscopies. The dots were found to be of similar size (ca. 2 nm) but differ in their composition and surface chemistry. The photostability of the QDs was found to correlate with their ability to produce reactive oxygen species (ROS) upon light activation. CdSe QDs produce hydroxyl radicals immediately after irradiation due to their modest photostability, while CdSe(S) QDs start to generate the hydroxyl radicals only once they start to be bleached (ca. 30 min). Cytotoxicity experiments conducted on Escherichia coli cells revealed that CdSe QDs were the more toxic despite being the least loaded in cadmium. In addition, consistent with ROS assays, the cytotoxicity of the CdSe QDs appeared light-dependent and is in accordance with a light-dependent oxidative stress observed with an oxyR-based whole cell biosensor. Our results demonstrate the crucial role played by nanoparticles synthesis process on their PL properties, their stability and their toxicity. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 118(8), pp. 3935-3941 
article DOI  
Abstract: The energetic performances of different "Silicalite-1-LiCl aqueous solution" systems were evaluated under high pressure. Depending on the LiCl concentration in the aqueous medium (0 M, 5 M, 10 M, 20 M), an increase of the intrusion and extrusion pressures and therefore of the stored (similar to 10, similar to 13, similar to 19, similar to 31 J/g) and restored (similar to 10, similar to 13, similar to 18, similar to 27 J/g) energies are observed. Thus, compared to the "Silicalite-1-water" system, the stored energy is tripled in the case of "Silicalite-1-LiCl 20 M" system. Several characterizations (XRD, TG, NMR, N-2 physisorption, ICP/OES, ...) have been realized before and after intrusion-extrusion experiments in order to reveal the presence or the lack of defects and the possible presence of lithium ions in the material after such experiments. At the short-range order, solid state NMR spectroscopy get evidence of the presence of Q(2) and Q(3) groups revealing the breaking of some siloxane bridges after the intrusion-extrusion steps and thus the creation of hydroxyl groups set in evidence by TG experiments. Only few traces of lithium (1 atom per unit cell) were found by ICP/OES analysis.

Vol. 44, pp. 17-23 
article DOI  
Abstract: In this paper, an aqueous-based route has been developed to prepare highly luminescent glutathione (GSH)-capped Mn-doped ZnS quantum dots (QDs). The dots obtained have an average diameter of 4.3 nm and exhibit the Mn2+-related orange luminescence with very low surface defect density. The highest photoluminescence was observed for a Mn2+ to Zn2+ molar ratio of 3%. Consecutive overcoating of the Mn:ZnS@GSH QDs by a ZnS shell was done, and the core/shell structured QDs exhibit a PL quantum yield of 23%. Transmission electron microscopy, X-ray powder diffraction, electron spin resonance, X-ray photoelectron spectroscopy, UV-visible spectroscopy and spectrofluorometry have been used to characterize the crystal structure, the doping status, and the optical properties of the doped-QDs. Our systematic investigation shows that Mn:ZnS/ZnS@GSH QDs are highly promising fluorescent labels in biological applications. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 11, pp. 63-79 
article DOI  
Abstract: We have developed a new type of mechanically responsive material on the basis of a plasma-modified soft biomaterial substrate (polypropylene surgical mesh). A first plasma deposited layer, enriched in a bioactive agent (silver nanoparticles), has been covered by a second plasma polymer layer that acts as a barrier to spontaneous release. The release of the active agent in a controlled manner was achieved by the presence of mechanically reversible fragmentations in the top-layer of deposited plasma polymer, induced by mechanical stimuli. Characterization of the material was performed by Scanning Electron Microscopy, Transmission Electron Microscopy, Attenuated Total Reflexion–Fourier Transform Infra-Red, X-ray Photoelectron, and Ultra Violet–Visible Spectroscopies. The antibacterial properties of the material have been verified.

Vol. 144, pp. 29-35 
article DOI  
Abstract: Cu-doped ZnS quantum dots (QDs) were synthesized in aqueous solution using 3-mercaptopropionic acid (MPA) as stabilizer. Transmission electron microscopy (TEM) results indicate that the Cu:ZnS nanocrystals distribute uniformly and the size is ca. 2.9 +/- 0.5 nm. These nanocrystals were successfully associated to anatase TiO2 nanoparticles to yield TiO2/Cu:ZnS photocatalysts. Morphological and optical properties of TiO2/Cu:ZnS nanocomposites were characterized by X-ray diffraction (XRD) analysis, TEM, and UV-vis and fluorescence spectroscopies. Photocatalytic activities of TiO2/Cu:ZnS nanocomposites were evaluated by the oxidation of salicylic acid aqueous solutions under UV light irradiation. Enhanced performances compared either to pure TiO2 nanoparticles or to undoped TiO2/ZnS nanocomposites were observed. Effects of the mass ratio of the TiO2 and Cu:ZnS and of the pH of the aqueous solution containing salicylic acid on the photocatalytic activities of TiO2 nanoparticles sensitized with Cu:ZnS QDs were also investigated.

Lajili, M., Limousy, L. and Jeguirim, M. Physico-chemical properties and thermal degradation characteristics of agropellets from olive mill by-products/sawdust blends 2014 Fuel Processing Technology
Vol. 126, pp. 215-221 
article DOI  
Abstract: This study aims to produce agropellets composed by olive waste, an olive mills by-product, blended with pine sawdust for 6 different mass fraction compositions. Thermal and physicochemical properties of these pellets such as moisture, ash content, bulk density and heating values were determined. In addition, thermogravimetric analyses were performed under inert and oxidative atmosphere in order to assess the thermal degradation behaviour of the produced agropellets. Results show that during the pelletization process, the high value of moisture in olive waste decreases. Values of ash content for each considered sample remain in the accepted agropellets French standards. Thermogravimetric analysis shows that the thermal degradation of the different pellets follows the usual behaviour of lignocellulosic materials. Furthermore, a quite continuous zone corresponding to the not readily char combustible part is detected during TGA under oxidative condition. However, a higher reactivity for PS/OW pellets is observed compared to those reported in literature. Such results prove that olive waste agropellets may be an alternative fuel for producing energy in domestic boilers. (C) 2014 Elsevier B.V. All rights reserved.

Vol. 10, pp. 863-876 
article DOI  
Abstract: In the present paper, the photoredox catalysis is presented as a unique approach in the field of photoinitiators of polymerization. The principal photocatalysts already reported as well as the typical oxidation and reduction agents used in both reductive or oxidative cycles are gathered. The chemical mechanisms associated with various systems are also given. As compared to classical iridium-based photocatalysts which are mainly active upon blue light irradiation, a new photocatalyst Ir(piq)(2)(tmd) (also known as bis(1-phenylisoquinolinato-N, C-2') iridium(2,2,6,6-tetramethyl-3,5-heptanedionate) is also proposed as an example of green light photocatalyst (toward the long wavelength irradiation). The chemical mechanisms associated with Ir(piq)(2)(tmd) are investigated by ESR spin-trapping, laser flash photolysis, steady state photolysis, cyclic voltammetry and luminescence experiments.

Vol. 100, pp. 152-157 
article DOI  
Abstract: The purpose of the present article is to evaluate the real fibre surface involved in the practical adhesion of a flax/epoxy system. The difference in practical adhesion evaluated by microbond tests between Hermes (tau(app) = 22.5 +/- 1.5 MPa) and Electra (tau(app) = 13.2 +/- 3.2 MPa) flax fibres varieties/epoxy systems could not be explained by their superficial surface chemistry evaluated by XPS. FTIR spectroscopy highlights a difference in biochemical composition and Laser Confocal microscopy evidences a resin penetration for the two flax fibres systems (1.7 +/- 0.7 mu m for Hermes and 2.2 +/- 0.8 mu m for Electra). Thus the effective surface or complex interphase will be by consequence the overall area where the resin and fibre are in contact, i.e. the entire area penetrated by resin. (C) 2014 Elsevier Ltd.

Abstract: An iridium(III) complex comprising three different cyclometalated phenylpyridine-based ligands was designed and synthesized. Interestingly, mixed-ligand complexes could be obtained by using a simple and straightforward procedure. A tris(heteroleptic) IrIII complex was obtained as a mixture of stereoisomers that could not be separated. Photophysical properties of the tris(heteroleptic) complex was investigated by UV/VIS absorption and luminescence spectroscopy, and compared with those of the parent homoleptic complexes. Modelling by time-dependent density functional theory (TD-DFT) was also performed to elucidate the nature and the location of the excited state, and to support the experimental results.

Hydrogen can be produced from biomass and biocatalysts can replace noble metals such as platinum. Hydrogenase enzymes arise as particularly efficient biocatalysts for H2 oxidation. However, bottlenecks must be overcome before the development of these biofuel cells: 1- biohydrogen production is rate limited, 2- many hydrogenases are inhibited by oxygen and CO, 3- the size of the enzymes limits their electrical connection, hence the current densities. This work will discuss some solutions to get through these limitations, such as controlled bacterium consortia to determine the biophysical parameters able to enhance bioproduction of H2, and the efficient immobilization of an O2-tolerant hydrogenase which allows the development of a new generation of H2/O2 biofuel cell.A multidisciplinary approach including microbiology, microscopies and electrochemistry was used for the study of a synthetic microbial consortium in view of the optimization of biohydrogen production. Electrochemical tools, associated to the full characterization of carbon materials, were used to design a H2/O2 biofuel cell.Numerous microorganisms can produce hydrogen by “dark fermentation”. Literature essentially reports the use of pure microbial cultures to produce biohydrogen from simple sugars. In this work one bacterium from Clostridium (H2 producer) and one from Desulfovibrio (H2 producer or consumer depending on its environment) have been studied as pure and mixed cultures. We demonstrate in this work (i) a physical interaction between the strains via nanotubes, (ii) an exchange of cytoplasmic constituents, (iii) a higher hydrogen production by the consortium compared to isolated bacteria. A modification in the metabolic pathway is proposed that can explain such results.1Besides, screening energetic pathways in exotic micro-organisms lead to the identification of a membrane-bound hydrogenase which oxidizes hydrogen into protons with high efficiency while presenting outstanding O2, CO and temperature resistances.2,3 When immobilized onto carbon nanotube networks and in combination with a multicopper oxidase for O2 reduction, this enzyme has been proved to be a valuable candidate in a preliminary H2/O2 biofuel cell.4Fishbone carbon nanofibers (CNFs) are other promising carbon materials which are electrically conductive, and bear lots of reactive sites due to the stacking of graphene cones. They can be quite easily functionalized for an efficient entrapment of proteins. We report in this work the use of such synthesized CNFs for modification of electrodes and immobilization of hydrogenase. We discuss the physico-chemical parameters that limit the efficiency of the bioelectrode, and define their optimization for a great enhancement of the current densities for H2 oxidation.Combined with a thermophilic multicopper oxidase at the cathode, immobilization of hydrogenase on CNFs allow to design a new generation of a high power H2/O2 biofuel cell able to be fed in the future with H2 produced from biomass.5References[1] Y.

Vol. 5, pp. 953-965 
article DOI  
Abstract: The present work is focused on better understanding of the interfacial interactions of SBA-15 mesoporous silica particles with flax fibers. In order to overcome the inherent complexity of flax fiber surface composition we have prepared model polysaccharide surfaces representing the main component of the flax fibers, e.g. cellulose, polygalacturonic acid (PGUA), and xyloglucan (XG) with thicknesses of about 200 nm, 100 nm, and 110 nm, respectively. The ξ-potential measurements of both silica and polysaccharides were performed in aqueous solutions as a function of pH and ionic strength. ξ-potential, AFM and SEM results supported the important role of electrostatic interactions in the silica adsorption on polysaccharide surfaces, since silica adsorption increased remarkably with ionic strength. The adsorption density of the SBA-15 onto the various polysaccharides was Cellulose > PGUA > XG, and the maximum was observed at pH = 4. Urea used as hydrogen bonds breaker reduced significantly the adsorption of SBA-15 on the polysaccharide surfaces, which highlighted the significant contribution of hydrogen bonding in the adsorption process. It was observed that most adsorbed SBA-15 particles were resistant to ultrasonic washing, which revealed their strong irreversible adsorption. Finally, direct adsorption experiments on both raw and treated real flax fibers yielded results consistent with those of model surfaces showing the important role of the surface fibers treatments on the improvement of the interfacial adhesion of the silica particles with flax fibers. The remarkable affinity of the SBA-15 particles with treated flax fibers is encouraging to design superinsulators composites with tuneable mechanical performances.

Abstract: A comparative study of the linear and nonlinear optical properties of a novel triphenylamine-pyrimidine alternated oligomer and its corresponding V-shaped quadrupolar monomer is presented. Both chromophores strikingly exhibit the same spectral shape when considering their respective one- and two-photon absorption spectra. This effect was attributed to a weak interchromophore coupling within the oligomer which exhibits a highly distorted geometry resulting in a strong reduction of the effective conjugation length. The recursive implementation of nine monomers into a three-dimensional architecture leads however to a cooperative enhancement of the two-photon absorption (2PA) cross-section with a [small delta]MAX of 5093 GM at 800 nm. This very high 2PA ability has been oriented to improve the two-photon induced polymerization efficiency of a bicomponent photoinitiator system implying a hexaarylbiimidazole used as a H-abstractor and an aliphatic amine used as a H-donor. The photosensitizing mechanism is investigated and we clearly show that the intrinsic photoinitiation efficiency of the oligomer is increased by a factor 3 as compared to its corresponding monomer. We therefore demonstrate that such a two-photon sensitizing strategy leads to a synergy effect combining a higher photoinitiation reactivity and a very large two-photon absorption cross-section.

Vol. 2(4), pp. 996-1006 
article DOI  
Abstract: A green photoinduced method for the modification of a biodegradable and biocompatible polymer, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV), has been successfully carried out using three types of monomers with potential antibacterial effects, i.e., 2-[(methacryloyloxy)-ethyl] trimethylammonium chloride (META), 2-[(methacryloylethyl)]-dimethyl-(3-sulfopropyl) ammonium (MESA) and 2-hydroxyethyl methacrylate (HEMA). The photografting process is conducted through a photoinduced free radical process employing a ketone-based photoinitiator in an aqueous medium. Under appropriate conditions, the photogenerated radicals abstract hydrogen atoms from the PHBHV backbone, thus initiating the UV-mediated photopolymerization of derived-(meth)acrylate monomers from the surface of PHBHV film. The photochemical mechanism of the ketones photolysis is entirely described by a electron spin resonance/spin trapping technique, and the modified-PHBHV films are extensively characterized by ATR-FTIR and water contact angle and XPS measurements. Finally, a primary investigation is conducted to support the antibacterial activity of the new functionalized biomaterial against Escherichia coli and Staphylococcus aureus.

Vol. 96, pp. 73-80 
article DOI  
Abstract: The preparation of antibacterial UV powder coatings dedicated to wood based panels is described in the present study. Two experimentalmethods were investigated: the generation of silver nanoparticles during the polymerization of UV powders and the introduction of a silvermodified beidellitewithin UV powder formulations.While the first method leads to some nanoparticle aggregation, this phenomenon was avoided with the second approach. Antibacterial activity was thus ensured by the presence of beidellite modified with silver cations. XRD, X-ray fluorescence, SEM/EDX and TEM analyses allowed a complete characterization of the Ag-beidellite before its incorporation within UV powder formulations. Real-time-FTIR spectroscopy fitted with an environmental cell was used to monitor the reactivity of UV powder formulations under UV light and temperature control. Resulting coatings were finally characterized by UV spectroscopy, DMA in tension mode, XRD, TEM and antimicrobial analyses. It was shown that the fully cured and homogeneous coatings exhibit high thermomechanical properties and antibacterial activity.

Vol. 4(4), pp. 2096-2102 
article DOI  
Abstract: Tensile deformation was applied to the naturally produced poly-gamma-glutamic acid, which can be enzymatically degraded and is, therefore, of interest for biomedical use. However, natural polyamino acids have a similar chemical structure to synthetic polyamides ("nylons"), which are known to feature strong inter-molecular hydrogen bonding that prevents large-scale molecular motion in their solid state. Through esterification, this hydrogen bonding was partially shielded, allowing orientation of the polyamino acid macromolecules through tensile deformation. An increase in Young's modulus and tensile strength was achieved of solution-cast films of the chemically modified poly-g-glutamic acids, consistent with enhanced uniaxial polymer chain orientation. The latter was confirmed by both wide-angle X-ray scattering and polarized Raman spectroscopy. The films thus produced were found to be non-cytotoxic. These mechanically tailorable, biocompatible polymers may be excellent candidates for use in musculoskeletal tissue engineering applications that have different loading requirements within the body.

Abstract: Four new push-pull dyes derived from Michler's ketones are investigated. These dyes, based on a donor--acceptor (D--A) structure, exhibit a tunable character according to the electron-withdrawing ability of the acceptor used. The new proposed structures can be used in high-performance photoinitiating systems. Remarkably, two of them are characterized by an excellent reactivity to initiate the free-radical polymerization of acrylates, the ring-opening polymerization of epoxides, as well as the synthesis of interpenetrating polymer networks (IPNs) under exposure to a laser diode at 457 nm. The chemical mechanisms are investigated by steady-state photolysis, fluorescence, and electron spin-resonance (ESR) experiments. image

Abstract: Nine new photoinitiating systems based on a combination of new and established dyes (having an end capped polyenic structure) with an iodonium salt have been synthesized and tested for the polymerization of divinylether and epoxy monomers upon a visible light exposure. They exhibit a strong absorption in the 350-650 nm range which well matches the visible light emission of different convenient visible light sources. Interestingly, very soft irradiation conditions can be employed. Excellent polymerization profiles have been obtained from selected dye iodonium salt combinations using a halogen amp or a laser diode à 457 nm. The chemical mechanisms associated with these novel photoinitiating systems are investigated by steady-state photolysis and ESR experiments. © 2014 Elsevier Ltd. All rights reserved.

Abstract: Direct photoredn. and photosensitization are powerful approaches for the in-situ synthesis in a polymer matrix. A silver-acrylate nanocomposite was prepd. using a novel one-pot strategy involving simultaneous photoinduced redn. and free radical polymn. processes. The fabrication of metal nanocomposite was performed using an acrylate functionalized oligomer (polyethylene glycol 600 diacrylate) and a silver salt (AgNO3). The formation of Ag-nanoparticles was followed by UV-Vis spectroscopy which shows a surface plasmon band at a wavelength range between 410 and 440 nm. Transmission electron microscopy revealed that the synthesized nanoparticles were spherical in shape with a diam. between 5 to 20 nm. The polymn. process was followed quant. by IR spectroscopy, monitoring the disappearance of the characteristic bands for the acrylate double bonds (1410 cm-1). The optimum conditions for obtaining the silver-polymer nanocomposites were detd. (silver precursor concn., molar ratio silver precursor/photoinitiator, irradn. time and intensity). A reaction mechanism was proposed to explain the polymn. rate dependence on the silver cations content. [on SciFinder(R)]

article DOI URL 
Abstract: The photophysical and nonlinear absorption properties of an oligo(phenylenethienylene)s series (nTBT) are investigated in this article. The length of the chromophore is gradually increased from one to four phenylenethienylene repeating units in order to evaluate the effects of the electronic delocalization on the two-photon absorption cross sections (δ). According to the excitation anisotropy measurements and quantum chemical calculations, two electronic transitions with distinctive symmetries, 1Ag → 1Bu and 1Ag → 2Ag, are present in the low energy region of the linear absorption spectrum. The lowest-energy transition 1Ag → 1Bu is one-photon allowed but two-photon forbidden and implies an electronic charge delocalization all along the oligomer segment whereas the weakly-allowed 1Ag → 2Ag transition exhibits a transition moment perpendicular to the average plane of the chromophore. The latter transition mainly contributes to the two-photon absorption ability of the oligomers. All derivatives are poorly solvatochromic and the breakdown of the mirror symmetry rule observed between absorption and fluorescence spectra at room temperature has been attributed to a photoinduced geometrical relaxation leading to a very efficient planarization process of the oligomer irrespective of its size. Increasing the oligomer length results in a slight shift of the two-photon absorption band (∼1300 cm(-1)) and in a drastic increase of δ from 2 ± 1 GM up to 802 ± 160 GM for 1TBT and 4TBT respectively. Based on a three-level model, it was found that main contributions to the strong increase of δ stem from the transition moments Mge and Mee' which are multiplied by a factor of 2.8 and 5 when going from 1TBT to 4TBT.

Ni, L.L., Dietlin, C., Chemtob, A., Croutxe-Barghorn, C. and Brendle, J. Hydrophilic/Hydrophobic Film Patterning by Photodegradation of Self-Assembled Alkylsilane Multilayers and Its Applications 2014 Langmuir
Vol. 30(33), pp. 10118-10126 
article DOI  
Abstract: While the photopatterning of self-assembled monolayers (SAMs) has been extensively investigated, much less attention has been given to highly ordered multilayer systems. By being both thicker (0.5-2 mu m) and more stable (cross-linked) than SAMs, patterned hybrid multilayers lend themselves more easily to the development of technology-relevant materials and characterization. This paper describes a facile two-step UV approach to patterning an alkylsilane multilayer by combining photoinduced self-assembly for multilayer synthesis and photodegradation through a mask for creating patterns within the film. In this second stage, a spatially resolved removal of the alkyl tail via a photooxidation mechanism took place, yielding regular and uniform silica microdomains. The result was a regular array of features (alkylsiloxane/silica) differing in chemical composition (hybrid/inorganic), ordering (crystal-like/disordered), and wettability (hydrophobic/hydrophilic). Such a photopattemed film was of utility for a range of applications in which water droplets, inorganic crystals, or aqueous polymer dispersions were selectively deposited in the hydrophilic silica microwells.

Vol. 16(2620), pp. 11 pages 
article DOI  
Abstract: In this study, silver nanoparticles (Ag NPs) were generated, functionalized, and stabilized using a one-step photochemical approach that does not require more than few minutes with a low power near UV LED source. A series of thiol-functionalized thioxanthone (TX) derivatives were prepared and used for the photoinduced synthesis of Ag NPs and their surface functionalization and stabilization. Upon illumination, Ag+ ions are reduced by free radicals generated through an oxidoreductive process occurring between excited TX groups and N-methyldiethanolamine. This process generates monodispersed silver nanoparticles with an average diameter about 2-7 nm depending on the TX derivative used. Due to the strong interaction between Ag atoms and thiol groups of the ligands, AgNPs are capped in situ by TX derivatives and exhibit remarkable stability in solution. Subsequent studies carried out on silver NPs/TX nanoassemblies (designed as AgNPs@S-TX) demonstrated their potentials in free radical photopolymerization of acrylate monomers.

Primary Chemical Sequence Ultimately Determines Crystal Thickness in Segmented All-Aliphatic Copolymers 2014 Macromolecules
Vol. 47(22), pp. 7890-7899 
article DOI  
Abstract: Thermoplastic elastomers (TPEs) are known to exhibit a phase-separated morphology which depends on their chemical structure and processing. The design of novel TPEs with predefined properties which are also independent of the material thermal history has so far remained a challenge. The focus of this work is on the semicrystalline morphology of all-aliphatic thermoplastic elastomers consisting of alternating polytetrahydrofuran (PTHF) segments and uniform glycine or beta-alanine bisoxalamide units. The thickness of the hard segment crystals was found to be highly monodisperse and independent of the sample thermal history. Using Nanocalorimetry, we observed that at cooling rates as high as 12 000 degrees C s1 the bisoxalamide segments can still crystallize although the crystallization temperature decreases by ca. 26 degrees C. The surface free energy of the hard block crystals is found to be extremely low (similar to 18 mJ m(-2)), which is likely due to the entropic contribution of soft segments forming tie chains bridging the neighboring crystals. To investigate the combined effect of crystal orientation and phase transitions, simultaneous time-resolved X-ray scattering and mechanical tensile tests were performed. Upon stretching, elastomeric PTHF segments with lengths above 1000 g mol(1) crystallize at ambient temperatures. Under these conditions two main morphologies were observed: at low strains the long axes of the fibril-like crystals were oriented parallel to the flow direction, whereas higher strains caused bisoxalamide crystal fragmentation and changed their preferential direction to the one perpendicular to the drawing direction. The chain tilts in the bisoxalamide crystals were calculated from the characteristic four-spot SAXS patterns and were similar to 5 degrees 16 degrees in the case of glycine end-groups and 24 degrees for alanine and propyl terminal groups. To our knowledge, this is the first attempt to determine the chain tilt for the nonlamellar crystals in block copolymers.

Vol. 118(14), pp. 7321-7328 
article DOI  
Abstract: Metal organic materials (MOFs) constitute very attractive materials for storage, separation, catalysis, and drug delivery because of their crystalline hybrid organic inorganic structures and their large porous volume. Here, we report the energetic behavior, in term of storage/restoration of mechanical energy, of ZIF-8 upon high pressure intrusion-extrusion of aqueous KCl, LiCl, and NaCl solutions of variable concentration. Comparison with the energetic performances of the "ZIF-8-water" system is performed. Whatever the nature of the electrolyte (KCl, LiCl, NaCl), an increase of the intrusion pressures and thereby of the stored energy are observed with the increasing of salt concentration. However, the three studied systems differ, at least for the highest concentrations, by behaving as a shock-absorber for KCl and as a bumper for NaCl and LiCl. A combination of several characterization techniques used before and after intrusion-extrusion experiments, i.e., X-ray diffraction, solid state NMR, and N-2 adsorption-desorption experiments, allows us to establish that the ZIF-8 network is preserved after such a treatment.

Vol. 118(37), pp. 21316-21322 
article DOI  
Abstract: Intrusion-extrusion experiments of water as well as electrolyte solutions (KCl 1 and 4 M) under high pressure were performed in metal-organic framework ZIF-71 (RHO-type structure) in order to study the performances of this system in energy absorption and storage. The experimental results reveal that "ZIF-71-water" system displays a perfect shock-absorber behavior, reproducible over several cycles. With this new studied system, the stored energy (25.5 J g(-1)) is almost doubled compared to that measured recently for "ZIF-8-water" system (13.3 J g(-1)) (SOD-type structure). When water is replaced by KCl aqueous solutions, a gain of intrusion pressure (74 and 96 MPa with KCl 1 and 4 M, respectively) is observed. However, for the highest salt concentration, the system evolves to a bumper behavior, and as confirmed by XRD analysis, the RHO-type structure collapses.

Vol. 118(38), pp. 22021-22029 
article DOI  
Abstract: Metal-organic framework-type Al-, Ga-, and Ga(OH,F)-MIL-53 have been characterized by solid-state NMR and powder X-ray diffraction (PXRD). H-1 2D double-quantum-single-quantum (DQ-SQ) magic angle spinning (MAS) NMR experiments unambiguously evidence two inequivalent water molecules in Al-MIL-53_np_H2O. A careful reinvestigation of the XRD structure of hydrated Al-MIL-53 proves, for the first time, the doubling of the unit cell supporting the presence of two inequivalent water molecules. One type of water molecule is located in the type A channel, interacting with the aromatic protons of framework organic moieties, whereas the other type of water molecule is in the type B channel far away from aromatic protons. Assignment of the corresponding H-1 resonances to each water molecule was possible. H-1 1D MAS NMR leads to the same conclusion (i.e., two inequivalent water molecules) for the isostructural gallium-based material thanks to the positioning of the hydrogen atoms by Rietveld refinement. Moreover, when Ga-MIL-53 is prepared with fluorine in the synthesis medium (giving Ga(OH,F)-MIL-53_np_H2O), the situation is different. 2D H-1-C-13 heteronuclear correlation MAS NMR, high-field H-1 DQ-SQ and radio-frequency-driven recoupling MAS NMR indicate that only one type of water molecule is found in this material, in agreement with the structure.

Parida, D., Serra, C.A., Garg, D.K., Hoarau, Y., Bally-le-Gall, F., Muller, R. and Bouquey, M. Coil Flow Inversion as a Route To Control Polymerization in Microreactors 2014 Macromolecules
Vol. 47(10), pp. 3282-3287 
article DOI  
Abstract: Linear and branched polymers of 2-(dimethylamino)ethyl methacrylate (PDMAEMA) were synthesized in flow by atom transfer radical polymerization (ATRP) and self-condensing vinyl copolymerization adapted to ATRP, respectively, in capillary type stainless steel coiled tube (CT) microreactors. Coil flow inversion (CFI) was introduced to achieve better mixing and narrower residence time distributions during polymerization. This strategy was adopted to improve control over macromolecular characteristics and polymer architecture. Polydispersity index (PDI), as an overall indicator of control over polymerization, was significantly lower for CFI in the case of linear PDMAEMA, 1.39 compared to 1.53 for CT. For branched polymers containing up to 10 mol % of inimer, a reduced PDI was also obtained for CFI microreactor. As for the branching efficiency, it was found to follow the following trend CFI > CT > batch reactor.

Parmentier, J., Gaslain, F.O.M., Ersen, O., Centeno, T.A. and Solovyov, L.A. Structure and Sorption Properties of a Zeolite-Templated Carbon with the EMT Structure Type 2014 Langmuir
Vol. 30(1), pp. 297-307 
article DOI  
Abstract: An ordered microporous carbon material was prepared by the nanocasting process using the EMC-2 zeolite (EMT structure type) as a hard template. X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed long-range ordering in the material that resulted from the negative replication of the host template. The carbon porous network replicating the zeolite structure was modeled by overlapped spherical voids with diameters determined from the XRD pattern that displayed up to six distinct peaks. The surface delimiting the 3D interconnected porosity of the solid has a complex morphology. The pore size distribution calculated from the XRD-derived structural model is characterized by a maximum at 1.04 nm related to the long-range-ordered microporous network. Complementary studies by immersion calorimetry revealed that most of the porosity was characterized by a size above 1.5 nm. These porous features were compared to data resulting from classical analysis (DR, DFT, BET, etc.) of the N-2 (77 K) and CO2 (low and high pressure, 273 K) physisorption isotherms. The limitations of these approaches are discussed in light of the pore size distribution consistently determined by XRD and immersion calorimetry measurements.

Vol. 118(2), pp. 873-880 
article DOI  
Abstract: We investigate charge transport of a randomly stacked few-layer graphene (FLG) film supported on quartz plate, as-prepared and after annealing treatment. The film is prepared by a simple, cheap and rapid hot spray technique from a FLG suspension, while FLG was obtained in our previous report by high yield mechanical exfoliation of pencil lead. According to Hall Effect measurements, the annealing process has strong impact on the conductivity of the FLG film, despite its low oxygen/defect content as confirmed by X-ray photoelectron spectroscopy (XPS), Raman, and photoluminescense spectroscopy. The nonohmic behavior along with a sheet resistance (R-square) decreases from a few tens to a few kilo-ohms is observed for the FLG film, whereas after thermal treatment, a constant R-square of 0.7 k Omega is recorded. The improvement of conductivity in the FLG film is attributed mainly to desorption of toluene from the FLG surface according to the TPD-MS analysis and not only to the oxygen decrease as generally reported.

Molecularly Smooth Single-Crystalline Films of Thiophene-Phenylene Co-Oligomers Grown at the Gas-Liquid Interface 2014 Crystal Growth & Design
Vol. 14(4), pp. 1726-1737 
article DOI  
Abstract: Single crystals of thiophene-phenelyne co-oligomers (TPCOs) have previously shown their potential for organic optoelectronics. Here we report on solution growth of large-area thin single-crystalline films of TPCOs at the gas liquid interface by using solvent-antisolvent crystallization, isothermal slow solvent evaporation, and isochoric cooling. The studied co-oligomers contain identical conjugated core (5,5'-diphyenyl-2,2'-bithiophene) and different terminal substituents, fluorine, trimethylsilyl, or trifluoromethyl. The fabricated films are molecularly smooth over areas larger than 10 X 10 mu m(2), which is of high importance for organic field-effect devices. The low-defect structure of the TPCO crystals is suggested from the monoexponential kinetics of the PL decay measured in a wide dynamic range (up to four decades) and from low crystal mosaicity assessed by microfocus X-ray diffraction. The TPCO crystal structure is solved using a combination of X-ray and electron diffraction. The terminal substituents affect the crystal structure of TPCOs, bringing about the formation of a noncentrosymmetric crystal lattice with a crystal symmetry Cc for the bulkiest trimethylsilyl terminal groups, which is unusual for linear conjugated oligomers. Comparing the different crystal growth techniques, it is concluded that the solvent-antisolvent crystallization is the most robust for fabrication of single-crystalline TPCOs films. The possible nucleation and crystallization mechanisms operating at the gas-solution interface are discussed.

Vol. 16(4), pp. 1366-1378 
article DOI  
Abstract: The discovery of oxygen and carbon monoxide tolerant [NiFe] hydrogenases was the first necessary step toward the definition of a novel generation of hydrogen fed biofuel cells. The next important milestone is now to identify and overcome bottlenecks limiting the current densities, hence the power densities. In the present work we report for the first time a comprehensive study of herringbone carbon nanofiber mesoporous films as platforms for enhanced biooxidation of hydrogen. The 3D network allows mediatorless hydrogen oxidation by the membrane-bound hydrogenase from the hyperthermophilic bacterium Aquifex aeolicus. We investigate the key physico-chemical parameters that enhance the catalytic efficiency, including surface chemistry and hierarchical porosity of the biohybrid film. We also emphasize that the catalytic current is limited by mass transport inside the mesoporous carbon nanofiber film. Provided hydrogen is supplied inside the carbon film, the combination of the hierarchical porosity of the carbon nanofiber film with the hydrophobicity of the treated carbon material results in very high efficiency of the bioelectrode. By optimization of the whole procedure, current densities as high as 4.5 mA cm(-2) are reached with a turnover frequency of 48 s(-1). This current density is almost 100 times higher than when hydrogenase is simply adsorbed at a bare graphite electrode, and more than 5 times higher than the average of the previous reported current densities at carbon nanotube modified electrodes, suggesting that carbon nanofibers can be efficiently used in future sustainable H-2/O-2 biofuel cells.

Abstract: A new generation of mediatorless H-2/O-2 biofuel cells was designed based on a hyperthermophilic O-2-tolerant hydrogenase and a thermostable bilirubin oxidase both immobilized on carbon nanofibers. A power density up to 1.5 +/- 0.2 mW center dot cm(-2) at 60 degrees C was reached. This first demonstration of a H-2/O-2 biofuel cell able to deliver electricity over a wide range of temperatures, from 30 C up to 80 degrees C, and over a large pH window, allows considering this device as an alternative power supply for small portable applications in various environments, including extreme ones.

Abstract: Abstract In this paper, a sequential process of elaboration of hybrid nanostructured composite films has been proposed. The combination of phase separation in poly(styrene-block-4vinylpyridine) (PS-P4VP) block copolymer leading to the formation of nanopores, and gold nanocolloids synthesis confined in the nanoholes has allowed the facile fabrication of hexagonally arranged gold nanoparticles (NPs) onto silicon wafer. In particular, the nucleation and growth of gold nanoparticles took place within the nanopores, where they are confined in both size and shape the formed Au NPs. The resulting hybrid nanoscomposite has been characterized by Atomic Force Microscopy (AFM) and X-Ray Spectroscopy (XPS). This facile and simple process represents an opened pathway to several technologically important materials fabrication such as hierarchical and ordered crystal architectures. Indeed, the approach based on solvent phase, which is particularly attractive due to its low energy requirement, and the safety and environmentally gentle processing conditions.

High-resolution thermal imaging with a combination of nano-focus X-ray diffraction and ultra-fast chip calorimetry 2014 Journal of Synchrotron Radiation
Vol. 21, pp. 223-228 
article DOI  
Abstract: A microelectromechanical-systems-based calorimeter designed for use on a synchrotron nano-focused X-ray beamline is described. This instrument allows quantitative DC and AC calorimetric measurements over a broad range of heating/cooling rates (<= 100000 K s(-1)) and temperature modulation frequencies (<= 1 kHz). The calorimeter was used for high-resolution thermal imaging of nanogram-sized samples subjected to X-ray-induced heating. For a 46 ng indium particle, the measured temperature rise reaches similar to 0.2 K, and is directly correlated to the X-ray absorption. Thermal imaging can be useful for studies of heterogeneous materials exhibiting physical and/or chemical transformations. Moreover, the technique can be extended to three-dimensional thermal nanotomography.

Ryzhikov, A., Khay, I., Nouali, H., Daou, J. and Patarin, J. Drastic change of the intrusion-extrusion behavior of electrolyte solutions in pure silica (star)BEA-type zeolite 2014 Physical Chemistry Chemical Physics
Vol. 16(33), pp. 17893-17899 
article DOI  
Abstract: High pressure water and electrolyte solutions intrusion extrusion experiments in pure-silica (star)BEA-type zeolite (zeosit beta) were performed in order to study the performances of these systems in energy absorption and storage. The "zeosil beta-water" system displays a bumper behavior with an intrusion pressure of 53 MPa and an absorbed energy of 8.3 J g(-1). For the "zeosil beta-LiCl aqueous solutions" systems the intrusion pressure increases with the LiCl concentration to 95, 111 and 115 MPa for 10, 15 and 20 M solution, respectively. However, for concentrations above 10 M, a transformation of the system behavior from bumper to shock-absorber is observed. The zeolite samples were characterized by several structural and physicochemical methods (XRD, TGA, solid-state NMR, N-2 physisorption, ICP-OES) before and after intrusion-extrusion experiments in order to understand the influence of the LiCl concentration on the intrusion-extrusion behavior. It is shown that the intrusion of water and LiCl solutions with low concentration leads to the formation of Si-(OSi)(3)OH groups, whereas no defects are observed under intrusion of concentrated LiCl solutions. A possible mechanism of LiCl solution intrusion based on separate intrusion of H2O molecules and Li(H2O)(x)(+) ions is proposed.

Vol. 4(71), pp. 37655-37661 
article DOI  
Abstract: Experimental water intrusion-extrusion isotherms were performed at room temperature on two pure silica MTT- and STF-type hydrophobic zeolites (zeosils) with 1D channel and cage pore systems, respectively by applying or releasing a high hydraulic pressure. These zeosils were obtained by hydrothermal synthesis in fluoride medium and characterized by structural and physicochemical methods before and after water intrusion. The system "MTT-type zeosil-water" displays a spring behavior with an intrusion pressure of 176 MPa and a stored energy of 5.3 J g(-1). No influence of water intrusion on the structure of MTT-type zeosil was found. The "STF-type zeosil-water" system shows a combination of shock-absorber and bumper behavior in the first cycle with an intrusion pressure of 51 MPa. Nevertheless in the following cycles the system demonstrates a spring behavior with an intrusion pressure of 38 MPa. Such behavior can be explained by the formation of silanol groups under intrusion in some pores confirmed by NMR spectroscopy and TG data.

Vol. 109, pp. 44-48 
article DOI  
Abstract: Chitosan film cast on a glass slide was exposed to acetic anhydride vapor, resulting in an acetylation gradient in the film, with preferential acetylation of the exposed surface. The difference in degree of acetylation between the two surfaces of the peeled film was confirmed by attenuated total reflection infrared spectroscopy. Upon immersion of the film in water, differential swelling occurred because the more highly acetylated surface absorbed less water, and the resulting bending moment caused self-scrolling with the more highly acetylated surface inside. Simultaneous peeling and scrolling of films with a thickness of micrometer order, using dilute aqueous hydrofluoric acid, afforded tightly rolled chitosan microtubes. This simple self-scrolling mechanism is potentially applicable for micro-scale design with various naturally occurring polymers. (C) 2014 Elsevier Ltd. All rights reserved.

Vol. 2(2), pp. 295-305 
article DOI  
Abstract: We report the synthesis, the photophysical and the two-photon absorption (2PA) properties of a series of octupolar bipyrimidine-based ligands incorporating N-substituted amines as terminal donor groups. The effect of replacing phenylvinylene pi-conjugated linkers by fluorenylvinylene ones was also investigated. The linear absorption spectrum of these compounds is dominated by an intensive charge transfer band which is sensitive to N-substitution and the pi-bridge nature. The excitation anisotropy spectrum indicates that this band encompasses multiple S-0 -> S-n transitions, whose occurrence is well rationalized on the basis of the Frenkel exciton model. The 2PA spectrum also corroborates the presence of several electronic transitions. In apolar or moderately polar medium, excited ligands mainly deactivate through a highly emissive intramolecular charge transfer (ICT) state localized within a single branch of the chromophore. In highly polar medium, the solvent-induced stabilization of the low emissive twisted intramolecular charge transfer (TICT) state leads to a severe quenching of the fluorescence. The same mechanism is observed upon complexation with Zn2+. According to single-crystal X-ray analyses, metal-induced planarization of the bipyrimidine chelating site was observed for the short length ligands. Such a dimensional change from D-2d to D-2h symmetry leads to a decrease of 2PA cross-sections with respect to the free ligands. A divergent effect is observed for the complex with the long length ligand since the three-dimensional structure is maintained which induces a sizeable increase of the 2PA cross-section with a maximum value of up to 2000 GM.

Vol. 25(14), pp. 145606 
article DOI  
Abstract: In this paper, we report on a continuous-flow microreactor process to prepare ZnO quantum dots (QDs) with widely tunable particle size and photoluminescence emission wavelengths. X-ray diffraction, electron diffraction, UV-vis, photoluminescence and transmission electron microscopy measurements were used to characterize the synthesized ZnO QDs. By varying operating conditions (temperature, flow rate) or the capping ligand, ZnO QDs with diameters ranging from 3.6 to 5.2 nm and fluorescence maxima from 500 to 560 nm were prepared. Results obtained show that low reaction temperatures (20 or 35 degrees C), high flow rates and the use of propionic acid as a stabilizing agent are favorable for the production of ZnO QDs with high photoluminescence quantum yields (up to 30%).

Vol. 16(21), pp. 4493-4500 
article DOI  
Abstract: We report here a simple method for controlling the crystal size and morphology of zeolitic imidazolate framework-8 (ZIF-8) nanocrystals in methanol solution. ZIF-8 crystals were prepared by mixing 2-methylimidazole (Hmim) with various zinc salts for 1 h and using a Hmim/Zn(+2) salt molar ratio of 8/1. All products prepared were assigned to a sodalite-type structure and both particle size and morphology were found to be dependent on the reactivity of the Zn(+2) salt. Small ZIF-8 crystals with diameters varying between ca. 50 and 200 nm were obtained with reactive zinc salts like Zn(acac)(2), Zn(NO3)(2), ZnSO4 or Zn(ClO4)(2) as demonstrated by SEM, TEM and DLS analyses. The use of ZnCl2, Zn(OAc)(2) or ZnI2 afforded crystals with sizes varying between ca. 350 and 650 nm. Finally, the low reactive ZnBr2 salt was found to generate microsized crystals. Taking ZIF-8 crystals prepared from Zn(NO3)(2), Zn(OAc)(2) and ZnBr2 as representatives and through thermogravimetric analysis and BET measurements, we also demonstrated that changes in particle size induced changes in stability and adsorption properties.

Vol. 118(22), pp. 11919-11927 
article DOI  
Abstract: New insights into the formation mechanism of a polymerized mesophase (space group Im (3) over barm) and its derived order mesostructured carbon phase (denoted FDU-16) were evidenced by a slight modification of its synthesis conditions using proton nuclear magnetic resonance (NMR) relaxometry (T-2 spin-spin relaxation time), dynamic light scattering (DLS), small-angle X-ray diffraction (SAXRD), N-2 physisorption (77 K), and scanning electron microscopy (SEM). The preparation of those materials is based on the self-assembly of a prepolymer (phenol-formaldehyde resin called resol) and a pyrolysable surfactant (Pluronic F127, PEO106PPO70PEO106). The former is the carbon precursor, and the latter is the pore structuring agent and also the porogen. The resol and the F127 solutions are usually mixed at room temperature before being heated at 65 degrees C to promote the polymerization of the resol into a polymerized mesophase that precipates. That phase is further carbonized into a mesostructured porous carbon. By a slight change of the mixing temperature around the critical micellar temperature of the F127 amphiphilic surfactant (similar to 25 degrees C), different formation pathways were observed, visually and thanks to DLS and NMR relaxometry techniques. It is proposed that the mixing temperature influences, in the early stage of the synthesis, both the resol-bound micelles (e.g., resol localization and solubility in the micelles) and the concentration of the free resol in the solution. It leads then to different kinetics of the free resol polymerization and to different evolutions of the intermediate colloidal particle populations with precipitation times ranging from 40 to 120 h. That synthesis parameter also influences the properties of the final mesostructured carbon materials by modifying their rhombododecahedral macroscopic morphology, their body-centered cubic mesostructural arrangement, and their porosity. That study highlights the high sensitivity of surfactant templated mesostructured materials toward the mixing temperature. That key parameter is rarely investigated and deserves to be systematically mentioned in the literature to avoid unexplained problems of reproducibility.

Vol. 15(7), pp. 2398-2406 
article DOI  
Abstract: In the fields of surgery and regenerative medicine, it is crucial to understand the interactions of proteins with the biomaterials used as implants. Protein adsorption directly influences cell-material interactions in vivo and, as a result, regulates, for example, cell adhesion on the surface of the implant. Therefore, the development of suitable analytical techniques together with well-defined model systems allowing for the detection, characterization, and quantification of protein adsorbates is essential. In this study, a protocol for the deposition of highly stable, thin gelatin-based films on various substrates has been developed. The hydrogel films were characterized morphologically and chemically. Due to the obtained low thickness of the hydrogel layer, this setup allowed for a quantitative study on the interaction of human proteins (albumin and fibrinogen) with the hydrogel by Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D). This technique enables the determination of adsorbant mass and changes in the shear modulus of the hydrogel layer upon adsorption of human proteins. Furthermore, Secondary Ion Mass Spectrometry and principal component analysis was applied to monitor the changed composition of the topmost adsorbate layer. This approach opens interesting perspectives for a sensitive screening of viscoelastic biomaterials that could be used for regenerative medicine.

Abstract: This article presents two high- temperature thermoplastic powders which were sintered by spark plasma sintering in order to get homogeneous mechanical properties. Dense polyimide (PI) and polyetheretherketone (PEEK) specimens were obtained at temperatures as low as 320 degrees C for PI and 200 degrees C for PEEK, respectively. Relative densities higher than 99% were reached for both materials. In order to characterize their properties, in situ measurements with compression and hardness tests were carried out on sintered samples. This method allowed to obtain polymeric materials with improved mechanical properties. (C) 2014 Wiley Periodicals, Inc.

Vol. 844, pp. 345-348 
article DOI  
Abstract: Non-rubber components (mainly proteins and lipids) in natural rubber (NR) play important roles for controlling the properties of NR. Crosslinking process creates intermolecular chemical bonds in order to obtain a three-dimensional network, resulting in more elastic rubber. Sulphur crosslinking is the most popular method and is applied in the present study. Two types of NR were prepared, namely, whole natural rubber (WNR) and purified natural rubber (PNR). PNR was deproteinized by centrifugation method and then acetone extraction. These rubbers were crosslinked by an efficient vulcanization (EV) system. They were cured for three curing times (1xt90, 2xt90, 3xt90) at 150°C. WNR presents shorter curing time than PNR because there are some phospholipids and proteins which are natural accelerators for curing reaction. The presence of non-rubber components seems to play a major role on crosslinking density and adhesion phenomenon for rubber/glass system. AFM images of WNR show more heterogeneity and roughness compared to PNR.

Vol. 48(1), pp. 190-198 
article DOI  
Abstract: The interaction of Fe(II) with clay minerals is of particular relevance in global geochemical processes controlling metal and nutrient cycles and the fate of contaminants. In this context, the influence of competitive sorption effects between Fe(II) and other relevant transition metals on their uptake characteristics and mobility remains an important issue. Macroscopic sorption experiments combined with surface complexation modeling and extended X-ray absorption fine structure (EXAFS) spectroscopy were applied to elucidate competitive sorption processes between divalent Fe and Zn at the clay mineral water interface. Sorption isotherms were measured on a synthetic iron-free montmorillonite (IFM) under anoxic conditions (O-2 < 0.1 ppm) for the combinations of Zn(II)/Fe(II) and Fe(II)/Zn(II), where the. former metal in each pair represents the trace metal (<10(-7) M) and the latter the competing metal at higher concentrations (10(-7) to 10(-3) M). Results of the batch sorption and EXAFS measurements indicated that Fe(II) is competing with trace Zn(II) for the same type of strong sites if Fe(II) is present in excess, whereas no competition between trace Fe(II) and Zn(II) was observed if Zn(II) is present at high concentrations. The noncompetitive behavior suggests the existence of sorption sites which have a higher affinity for Fe(III), where surface-induced oxidation of the sorbed Fe(II) to Fe(III) occurred, and which are not accessible for Zn(II). The understanding of this competitive uptake mechanism between Fe(II) and Zn(II) is of great importance to assess the bioavailability and mobility of transition metals in the natural environment.

Abstract: Abstract The low vapor pressure of explosives makes the gaseous detection challenging and drives even the particle detection. There is a need to provide easy portable systems, highly spreadable. A bio-inspired concept was developed to detect explosive vapors with unprecedent sensitivities. Vertically aligned TiO2 nanotubes were grown on a cantilever. The sensors successfully detected trinitrotoluene (TNT) and pentaerythritol tetranitrate (PETN) with a minimum threshold concentration down to 0.8 ppt. This work describes also the investigations undertaken to develop the characterization of explosives by nanocalorimetry, which is able to identify explosives in form of single particles.

Vol. 2(2), pp. 277-285 
article DOI  
Abstract: A versatile, fast and easy route towards preparation of metal-oxide nanostructures by a full-optical method at room temperature is presented here. The concept relies on the preparation of photosensitive metal-oxo clusters (MOCs) that can be crosslinked and mineralized in a single step process, by Deep-UV (DUV) irradiation (ArF laser emission band at 193 nm). The oxo-clusters are prepared by complexation between metal alkoxides and methacrylic acids followed by a partial hydrolysis. These molecular building blocks are designed to absorb DUV light and they can react from an excited state to give rise to crosslinking reactions. Photocrosslinking of Ti, Zr and Hf oxo-clusters was investigated by means of in situ FTIR and spectroscopic ellipsometry. In the case of Ti-oxo clusters, we demonstrate that the material can be fully mineralized into TiO2 by DUV irradiation. A photocatalytic process involving TiO2 nanoparticles is proposed to explain the DUV mineralization process. Finally, we used DUV interferometric lithography to illustrate nanopatterning based on these photoresists. These inorganic photoresists open new doors towards room temperature preparation of high-resolution inorganic nanostructures with strong interest for practical applications in electronics, optics, photonics or biology.

Vol. 46(2), pp. 92-97 
article DOI  
Abstract: By deposition in ultra-high vacuum of cobalt on a Ge(111)-c(2x8) surface, Mocking et al. obtained a root 13 x root 13 - R13.9 degrees surface reconstruction. In the present paper, we analyse the related atomic structure, proposed by these authors, by means of density functional theory calculations. The surface presents ordered clusters that consist of six Ge atoms arranged in a triangle, lying above three Co atoms. The latter are located at substitutional positions within the top plane of the Ge(111) first bilayer. These clusters are similar to what is obtained on part of the Co-induced Si(111) root 13 x root 13 - R13.9 degrees surface. For this surface, the clusters are terminated either by six Si atoms or by one, two or three adatoms above the six Si atoms. As the Co-Ge clusters systematically display six protrusions in the scanning tunnelling microscopy measurements by Mocking et al., we investigated why Ge adatoms are not present. Comparison of the Gibbs energy, interatomic distances, as well as charge density indicates that Ge adatoms on top of Co-Ge clusters are less stable than Si adatoms in the Co-Si system.

Vol. 198(0), pp. 175-184 
article URL 
Abstract: Abstract The synthesis of LiFePO4-carbon mesoporous composites by a one-pot soft-template approach is reported along with their performances as positive electrodes for Li-ion batteries. The synthesis is based on the multi-constituent co-assembly of triblock copolymer, resol and (Li, Fe, P) precursors followed by thermal treatment to in-situ generate the carbon matrix with embedded LiFePO4 particles. The effects of the Fe/Li precursor type and the thermal annealing temperature on the phase formation, mesostructural regularity, porosity and Fe oxidation state were systematically investigated by a large panel of analysis techniques. This new synthesis method allowed the successful synthesis of mesoporous LiFePO4-carbon composites with high surface area, defined pore size and small homogenously distributed LiFePO4 particles (20-50 nm). These composites can be used as electrodes without extra carbon black additive and demonstrate high rate capability (up to 10 C) with a significant capacity contribution from carbon.

Abstract: Chalcone derivatives are proposed as novel photoinitiators for polymerization upon exposure to visible light (even under soft irradiation conditions: blue LED bulb at 462 nm, halogen lamp, and sunlight). Remarkably, these structures are highly versatile allowing access to photoinitiating systems for (i) the free radical polymerization of acrylates, (ii) the cationic polymerization of epoxides and vinyl ethers, (iii) the synthesis of interpenetrated polymer networks (IPNs) and (iv) the thiol-ene processes. Excellent polymerization profiles are obtained. The initiation mechanisms are analyzed through ESR, steady state photolysis, cyclic voltammetry, laser flash photolysis and fluorescence experiments.

Abstract: Novel photoinitiators based on a phenazine scaffold are proposed for the ring opening polymerization of epoxy monomers as well as the free radical polymerization of (meth)acrylates. Good to excellent polymerization profiles can be obtained upon different easily accessible, energy saving and cheap LEDs (385, 395 and 405 nm) as well as a diode laser at 405 nm or halogen lamp opening new fields for polymer synthesis upon soft and convenient irradiations. These compounds can be particularly attractive as high performance photoinitiators in the 350-425 nm range. The initiation mechanisms are investigated in detail through fluorescence, cyclic voltammetry, steady state photolysis and electron spin resonance (ESR) experiments. (C) 2014 Elsevier Ltd.

On the Synthesis, Characterization and Reactivity of N-Heteroaryl-Boryl Radicals, a New Radical Class Based on Five-Membered Ring Ligands 2014 Chemistry-a European Journal
Vol. 20(17), pp. 5054-5063 
article DOI  
Abstract: The synthesis and physical characterization of a new class of N-heterocycle-boryl radicals is presented, based on five membered ring ligands with a N(sp(2)) complexation site. These pyrazole-boranes and pyrazaboles exhibit a low bond dissociation energy (BDE; BH) and accordingly excellent hydrogen transfer properties. Most importantly, a high modulation of the BDE(BH) by the fine tuning of the N-heterocyclic ligand was obtained in this series and could be correlated with the spin density on the boron atom of the corresponding radical. The reactivity of the latter for small molecule chemistry has been studied through the determination of several reaction rate constants corresponding to addition to alkenes and alkynes, addition to O-2, oxidation by iodonium salts and halogen abstraction from alkyl halides. Two selected applications of N-heterocycle-boryl radicals are also proposed herein, for radical polymerization and for radical dehalogenation reactions.

Abstract: Poly(n-butyl acrylate) networks were prepared by conducting click chemistry between dialkyne alkoxyamines and azide functionalized star-like oligomers synthesized by ATRP. The dissociation of alkoxyamines under UV irradiation was exploited to cleave the junctions between the network of star-like precursors. The efficiency of the cleavage, generating dangling nitroxides and increased mobility of poly(n-butyl acrylate) segments, was examined by ESR monitoring. The network progressively reformed after irradiation via the recombination of radical species. These reactions resulted in self-healing behavior, which was observed by AFM.

Vol. 4(31), pp. 15930-15936 
article DOI  
Abstract: 1,3-Bis(dicyanomethylidene) indane is presented as a new initiator for ring opening polymerization of epoxides at RT. This compound behaves as a strong acid (AH) with an associated basic form (A(-)) that does not inhibit the propagation of the cationic polymerization. Remarkably, A(-) is characterized by a strong visible light absorption and can also photosensitize iodonium salt decomposition. A new iodonium salt based on A(-)as a counter-anion is proposed. This latter compound exhibits unusual properties: (i) excellent absorption in the 300-700 nm wavelength range and (ii) a free radical initiating ability for lambda > 300 nm. The chemical mechanisms are investigated by ESR, fluorescence and steady state photolysis experiments.

Vol. 215(16), pp. 1514-1524 
article DOI  
Abstract: New thiophene derivatives (THs) are prepared and proposed here as new photoinitiators in combination with an iodonium salt for the cationic polymerization of vinylethers. They contain electron donor and electron acceptor (D-A) moieties and exhibit red-shifted absorption spectra. They allow the use of a long-wavelength excitation at 532 nm using a laser diode. Irradiation from a green light-emitting diode (LED) at 514 nm can also be used. The high reactivity upon irradiation from the low-intensity green LED highlights the high reactivity of the proposed structures. Interesting polymerization profiles (with conversions up to 70%) are obtained. The initiation step mechanisms are analyzed by electron spin resonance (ESR), fluorescence measurements, steady-state photolysis, and laser flash photolysis experiments.

Abstract: The energetic performance of different "Silicalite-1 - aqueous medium" systems was evaluated under high pressure. Depending on the nature of the aqueous medium, high intrusion and extrusion pressures and therefore stored and restored energies are observed. Thus, compared to the "Silicalite-1 - water" system, the stored energy is tripled in the case of "Silicalite-1 - LiCl, 3H(2)O" system. (C) 2013 Elsevier B.V. All rights reserved.

Vol. 844, pp. 369-372 
article DOI  
Abstract: Natural rubber (NR) is a very useful elastomer and renewable polymer with outstanding properties compared to synthetic elastomers. However, as a natural polymer, the non-rubber species (proteins, phospholipids, carbohydrate, etc.) have to be considered carefully for the understanding of the surface and interfacial properties. Especially these components can markedly affect the frictional and adhesive properties of the rubber surface. Although many methods can be used to modify the surface properties, chlorination remains one of the easiest way. The present study deals with surface modification of peroxide crosslinked NRs and synthetic cis-1,4 polysioprene as reference samples by chlorination. Surface and frictional properties of these different rubbers were analyzed by various complementary techniques The influence of critical parameters on wetting, frictional and mechanical properties were investigated and will be discussed

Vol. 6(3)ACS Applied Materials & Interfaces, pp. 1662-1674 
article DOI URL 
Abstract: Maleic anhydride plasma polymer was deposited at the surface of carbon fibers and functionalized with vinyl and thiol groups to improve its adhesion strength with an acrylate matrix cured by an electron beam. A characterization of the fiber surface properties was done before and after coating (topography, surface chemistry, and surface energy). Sharp improvements of the interfacial shear strength (+ 120%), measured by a micromechanical test derived from the pull-out test, were obtained and, to the best of our knowledge, never reported before. The values were close to the ones obtained with a thermal cure. The comparison of this approach with other types of surface treatments (oxidation, grafting of coupling agents) enabled the establishment of a general strategy for the improvement of the interfacial adhesion in carbon fiber composites cured by an electron beam and potentially the improvement of their mechanical properties. This strategy is based on a high surface density of functionalities that are generating covalent bonding during the polymerization of the matrix and on the insertion of a polymer layer strongly attached to the fiber surface and acting as a buffer between the fiber surface and the matrix to counteract the generation of stress in the interphase.

Vautard, F., DENTZER, J., NARDIN, M., SCHULTZ, J. and Defoort, B. Influence of surface defects on the tensile Strength of carbon fibers 2014 Applied surface science
Vol. 322, pp. 185-193 
article DOI  
Abstract: tThe mechanical properties of carbon fibers, especially their tensile properties, are affected by internaland surface defects. In order to asses in what extent the generation of surface defects can result in aloss of the mechanical properties, non-surface treated carbon fibers were oxidized with three differentsurface treatment processes: electro-chemical oxidation, oxidation in nitric acid, and oxidation in oxy-gen plasma. Different surface topographies and surface chemistries were obtained, as well as differenttypes and densities of surface defects. The density of surface defects was measured with both a physicalapproach (Raman spectroscopy) and a chemical approach (Active Surface Area). The tensile propertieswere evaluated by determining the Weibull modulus and the scale parameter of each reference, aftermeasuring the tensile strength for four different gauge lengths. A relationship between the tensile prop-erties and the nature and density of surface defects was noticed, as large defects largely control the valueof the tensile strength. When optimized, some oxidation surface treatment processes can generate sur-face functional groups as well as an increase of the mechanical properties of the fibers, because of theremoval of the contamination layer of pyrolytic carbon generated during the carbonization of the poly-acrylonitrile precursor. Oxidation in oxygen plasma revealed to be a promising technology for alternativesurface treatment processes, as high levels of functionalization were achieved and a slight improvementof the mechanical properties was obtained too.

Versace, D.L., Fouassier, J.P. and Lalevee, J. The First Photochemical In Situ Production of Ti-Based Nanoparticles: A S H 2 Strategy Using Bis( cyclopentadienyl) titanium Dichloride ( Cp 2 TiCl 2) 2014 Macromolecular Rapid Communications
Vol. 35(8), pp. 821-826 
article DOI  
Abstract: Bis(cyclopentadienyl)titanium dichloride (Cp2TiCl2) is a high performance additive under UV light activation for both i) radical photopolymerization reactions (when added to a Type I photoinitiator such as 2,2-dimethoxy-2-phenylacetophenone, the oxygen inhibition is reduced) and ii) a concomitant in situ photoinduced and oxygen mediated formation of Ti-based nanoparticles (diameters ranging from 45 to 220 nm). The photochemical properties of Cp2TiCl2 are investigated by steady state photolysis and electron spin resonance, and its photoinitiation ability checked. The nanoparticles (NPs) are well characterized by transmission electron microscopy. The high reactivity of Cp2TiCl2 under air is ascribed to a bimolecular homolytic substitution (the S(H)2 process is clearly demonstrated by density functional theory calculations and ESR experiments), which converts the peroxyls into new efficient initiating radicals. The photochemical in situ incorporation of Ti NPs has never previously been reported. The synthesis of metal nanoparticles by a S(H)2 approach instead of the reduction of a metal salt appears to be a promising original method. image

Vol. 6, pp. 8250-8256 
article DOI URL 
Abstract: We studied the formation of hydrogen-bonded supramolecular polymers of Ethyl Hexyl Urea Toluene (EHUT) on a gold (111) surface by low temperature scanning tunneling microscopy. Tunneling spectroscopy performed along an individual molecule embedded in a self-assembled layer revealed strong changes in the value of the HOMO-LUMO gap. A variation of the LUMO state is attributed to the effect of space charge accumulation resulting from anisotropic adhesion of the molecule. In addition, for specific tunneling conditions, changes induced through the formation of hydrogen bonds became visible in the differential conductance (dI/dV) maps; isolated molecules, hydrogen bonded dimers and supramolecular polymers of EHUT were distinguishable through their electronic properties.

Abstract: A novel 3D metal-organic framework based on tetranuclear copper Secondary Building Units, [Cu2(μ3-OH)(4-oip)(DMF)]·DMF·2H2O (JUC-76) (4-oip = 4-hydroxyisophthalic, DMF = N,N-dimethylformamide, and JUC = Jilin University China), has been synthesized under solvothermal conditions. It crystallizes in monoclinic symmetry with space group P21/n. JUC-76 possesses a three-dimensional network with one-dimensional rhombic channels of approximately 13.6 × 8.5 Å2 along the [100] direction. The resulting structure of JUC-76 is a distorted rutile topology with one 3-connected organic node and one 6-connected inorganic node. And its Schläfli symbol is (4·62)2(42·610·83). In addition, JUC-76 exhibits fluorescence emission at 446 nm, and a dominant anti-ferromagnetic interaction between the Cu (II) ions.

Abstract: The monomeric (DPPDT) and polymeric (PDQT) diketopyrrolopyrrole–thiophene derivatives combined with an iodonium salt or an amine (and optionally an additive) are used as photoinitiating systems to initiate the cationic polymerization of epoxides or divinyl ethers, radical polymerization of acrylates and thiol–ene polymerization under different irradiation sources (i.e. very soft halogen lamp, laser diodes at 473 nm, 532 nm and 808 nm). The DPPDT based systems are very efficient upon the green light exposure. Remarkably, these systems are characterized by a higher efficiency than references based on camphorquinone, a well known photosensitizer for visible light. The photochemical mechanisms are studied by steady state photolysis, fluorescence, cyclic voltammetry, laser flash photolysis and electron spin resonance spin trapping techniques.

Vol. 47(12), pp. 3837-3844 
article DOI URL 
Abstract: Three copper complexes (E1, G1, and G2) with different ligands in combination with an iodonium salt (and optionally another additive) were used to generate radicals upon soft visible light exposure (e.g., polychromatic visible light from a halogen lamp, laser diodes at 405 and 457 nm, LEDs at 405 and 455 nm). This approach can be worthwhile and versatile to initiate free radical photopolymerization, ring-opening cationic photopolymerization, and the synthesis of interpenetrating polymer networks. The photochemical mechanisms for the production of initiating radicals are studied using cyclic voltammetry, electron spin resonance spin trapping, steady state photolysis, and laser flash photolysis techniques. The photoinitiation ability of the copper complexes based photoinitiating systems are evaluated using real-time Fourier transform infrared spectroscopy. G1 and G2 are better than the well-known camphorquinone (CQ)-based systems (i.e., TMPTA conversion = 18%, 35%, 48%, and 39% with CQ/iodonium salt, CQ/amine, G1/iodonium salt, and G2/iodonium salt, respectively; halogen lamp exposure). Interestingly, some of these systems are also better than the well-known type I phosphine oxide photoinitiator (BAPO) clearly showing their high performance. These copper complexes can be used as highly efficient catalysts in photoredox catalysis.

Abstract: Novel naphthalene derivatives have been designed to be used as versatile photoinitiators upon a laser diode (405 nm), a polychromatic halogen lamp, or an UV LED (385 nm) exposure. The reactive species produced from photoinitiating systems based on one particular naphthalene derivative (NA3) and an iodonium salt, N-vinylcarbazole, an amine or 2,4,6-tris(trichloromethyl)-1,3,5-triazine were particularly efficient for cationic, radical, IPN and thiol–ene photopolymerizations upon low light intensity exposure. The best proposed systems exhibit a higher efficiency than references systems for visible lights (i.e., camphorquinone CQ-based photoinitiating systems). The mechanisms for the photochemical generation of reactive species (i.e., radicals and cations) were studied by electron spin resonance spin-trapping, fluorescence, cyclic voltammetry, laser flash photolysis, and steady state photolysis techniques.

Xiao, P., Dumur, F., Zhang, J., Gigmes D.and Fouassier, J. and Lalevee, J. Copper Complexes: Effect of Ligands on Their Photoinitiation Efficiencies in Radical Polymerization Reactions under Visible Lights. 2014 Polym. Chem.
Vol. 5, pp. 6350-6357 
article DOI URL 
Abstract: Copper complex (CuC) based photoinitiating systems (PISs) usable under visible lights have emerged as suitable substitutes for the expensive metal complexes e.g. ruthenium or iridium containing compounds. It is expected that the ligands present on the CuCs can significantly affect the photochemical properties (such as light absorption, luminescence lifetimes) or the redox potentials and therefore should play an important role in the photoinitiation efficiency of CuC based PISs. In the present paper, for a better understanding of the effect of ligands on the photoinitiation ability of CuCs, twenty three different copper complexes have been synthesized. The light absorption properties, the photostabilities and the photoreactivities of CuC/iodonium salt (Iod) couples will be specifically investigated. The photoinitiation ability of various PISs (CuC/Iod, CuC/Iod/N-vinylcarbazole, CuC/alkyl bromide/methyl diethanolamine) in the free radical polymerization of acrylates under different visible light irradiations (near UV or visible LEDs at 405 and 455 nm, laser diodes at 405, 457 and 532 nm, halogen lamp) will be checked. It reveals that some of the CuC based PISs even exhibited better efficiency than the well-known reference PISs: bisacylphosphine oxide - BAPO (representative of highly reactive Type I photoinitiators) and camphorquinone - CQ (representative of Type II systems).

Vol. 47(1), pp. 26-34 
article DOI  
Abstract: Newly synthesized indanedione derivatives combined with an iodonium salt, N-vinylcarbazole, amine, phenacyl bromide, or 2,4,6-tris(trichloromethyl)-1,3,5-triazine have been used as photoinitiating systems upon very low visible light intensities: blue lights (e.g., household blue LED bulb at 462 nm) or even a halogen lamp exposure. One of them (ID2) is particularly efficient for cationic, radical and thiolene photopolymerizations as well as for the synthesis of interpenetrated polymer networks (IPNs). It can be useful to overcome the oxygen inhibition. ID2 based photoinitiating systems can also be selected for the reduction of Ag+ and the in situ formation of Ag(0) nanoparticles in the synthesized polymers. The (photo)chemical mechanisms are studied by electron spin resonance spin trapping, fluorescence, cyclic voltammetry, laser flash photolysis, and steady state photolysis techniques.

Vol. 391, pp. 121-129 
article DOI  
Abstract: Fe deposits were performed on LaAlO3 (001) by molecular beam epitaxy at different substrate temperatures. Chemical and structural characterizations were carried out in-situ, by X-ray photoelectron spectroscopy (XPS), reflection high-energy electron diffraction (RHEED), X-ray photoelectron diffraction (XPD), and ex-situ by high-resolution transmission electron microscopy ( HRTEM). This temperature dependence study indicates that the growth of Fe is epitaxial in a tight temperature window around 500 degrees C with a single epitaxial relationship, where the Fe and LaAlO3(001) lattices are brought into coincidence by a 45 rotation around the common [001] axis. This typical configuration via Fe-O bonds formation at the interface allows a minimization of the elastic strain inside Fe islands which follow a Volmer-Weber growth mode. Beyond a given thickness, and in agreement with the strain relaxation, Fe islands exhibit (001) facets, leading to islands coalescence and a possible iron 2D layer formation. (C) 2014 Elsevier B.V.

Intertwined Lamello-Columnar Coassemblies in Liquid-Crystalline Side-Chain Pi-Conjugated Polymers: Toward a New Class of Nanostructured Supramolecular Organic Semiconductors 2014 Macromolecules
Vol. 47(5), pp. 1715-1731 
article DOI  
Abstract: A set of liquid-crystalline polymeric systems, associating at once the regioregular polythiophene backbone and pending mesogenic triphenylenes, is reported. Two series, namely regular homopolymers and alternating copolymers, were prepared by adapting a Grignard metathesis-based methodology, allowing some of the relevant structural parameters to be sequentially and independently modified. The thermal and self-organization behaviors of these uncommon macromolecular systems were investigated by polarized-light optical microscopy, differential scanning calorimetry and temperature-dependent small-angle X-ray scattering. Most polymers self-organize into mesophases possessing intertwined lamello-columnar morphologies, resulting from the simultaneous coexistence of lamellar and columnar sublattices. The successful preparation of oriented thin films of several of these polymeric homologues allowed further investigations by atomic force microscopy, transmission electron microscopy, electron diffraction, and grazing-incidence SAXS, which provided a deeper insight of the intricate supramolecular organizational modes, including the complete elucidation of the structure of the lamello-columnar mesophases. This simple and versatile strategy provides a route to elaborate polymeric materials incorporating two intercalated separate pathways toward charge carrier transport, of paramount importance for future electronic and optoelectronic applications.

Abstract: Three novel photoinitiators, namely (2,2'-bithiophen-5-yl)(4-(N,N'-dimethylaminophenyl)ketone, 5,10-dimethoxybenzo[j]fluoranthene and 6,6'-(((1E,1'E)-(2,5-bis(octyloxy)-1,4-phenylene)bis(ethene-2,1-diyl))bis(4,1-phenylene))bis(1,3,5-triazine- 2,4-diamine) applicable to different near UV or visible LEDs (385 nm, 395 nm, 405 nm or cold white LED) have been developed. When incorporated into multicomponent photoinitiating systems PISs (in the presence of iodonium salt (and optionally N-vinyl carbazole) or amine/alkyl halide couples), they exhibit quite excellent photoinitiating abilities for the cationic polymerization CP of epoxides or the free radical polymerization FRP of methacrylates under air. Compared to the corresponding camphorquinone-based systems, the newly developed photoinitiating systems display noticeably higher polymerization efficiencies under air (epoxide conversions = 31-55% vs similar to 0%, halogen lamp exposure; methacrylate conversion = 56-66% vs 0-8%, LED irradiation). These systems are very interesting to overcome the oxygen inhibition. The photochemical mechanisms have been studied by steady state photolysis, electron spin resonance spin trapping, fluorescence, cyclic voltammetry, and laser flash photolysis techniques.

Abstract: 2-(4-Methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5-triazine (R-Cl) appears as a versatile high-performance photoinitiator (PI) under LED exposure at 385, 395 or 405 nm (intensities in the range [similar]9-140 mW cm-2). It has been used as an efficient Type I cleavable PI for the free radical photopolymerization (FRP) of (meth)acrylates under near UV or visible LED irradiation. When combined with various additives (i.e. amine, iodonium salt, or N-vinylcarbazole), the R-Cl based photoinitiating systems can exhibit an even higher efficiency than R-Cl alone. Remarkably, R-Cl alone as well as the R-Cl/additive systems lead to a photoinitiation ability for the FRP of methacrylate under air at 405 nm that is better than that of well-known commercial photoinitiators (e.g. bisacylphosphine oxide (BAPO), 2,4,6-trimethylbenzoyl-diphenyl-phosphineoxide (TPO), or 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1 (BDMB)). In addition, the R-Cl/iodonium salt/N-vinylcarbazole combination can also initiate the cationic polymerization of epoxides in the 385-405 nm range. Moreover, the photochemistry of these systems has been investigated by steady state photolysis, molecular orbital (MO) calculations, and electron spin resonance spin trapping techniques.

Abstract: Abstract Two naphthalimide derivatives (DMAENs) containing tertiary amine groups have been designed and synthesized. Upon exposure to near UV and visible LEDs (365 nm-455 nm), they lead to radicals without adding a hydrogen donor and, in combination with 2,4,6-tris(trichloromethyl)-1,3,5-triazine, an iodonium salt or N-vinylcarbazole, they produce radicals and cations. Compared to the well-known camphorquinone or bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide photoinitiator, the novel DMAENs containing photoinitiating systems are characterized by a very high reactivity for both the free radical polymerization of acrylates and the cationic polymerization of epoxides. This outstanding performance paves the way for polymerization in soft conditions (e.g. upon LED irradiation). The photochemical mechanisms are studied by Molecular Orbitals MO calculations, steady state photolysis, fluorescence, cyclic voltammetry, electron spin resonance spin trapping and laser flash photolysis techniques.

Vol. 131(22), pp. 41064 
article DOI  
Abstract: Tannin from larch (Larix gmelini) bark extracts, as a natural renewable resource, was used to prepare tannin-urea-formaldehyde (TUF) resin. The chemical structures of larch tannin and TUF resin were characterized by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and C-13 nuclear magnetic resonance. The thermal behaviors of TUF resin were evaluated by differential scanning calorimetry (DSC) and thermomechanical analysis (TMA). The performances of TUF resin were investigated by measuring the bond strength and formaldehyde emission of its bonded plywood. It was clearly shown that larch tannin is mainly composed of prodelphinidin repeating units. Phenolic groups were introduced into TUF resin mainly linked by methylene bond. Larch tannin has an adverse effect on the resin curing. However, it promoted the rigidity and flexibility of the glued system and upgraded the properties of plywood. Therefore, larch tannin could be applied in the modification of urea-formaldehyde resin. (C) 2014 Wiley Periodicals, Inc.

Abstract: Based on nanoscale photopolymerization triggered by the dipolar surface plasmon mode, we developed a light-emitting gold nanoparticle/Eosin Y-doped polymer hybrid nanostructure. Due to the anisotropic spatial distribution of the dipolar surface plasmon mode during photopolymerization, this nano-emitter is anisotropic in both geometry and emission. The trapped dye molecules in the hybrid nanostructure display fluorescence intensity that is dependent upon the polarization of the incident excitation light. This nano-emitter further allows the photo-selection of fluorescence configuration (i.e., molecule concentration and refractive index of active medium) by controlling the incident polarization.

Abstract: Hybrid nanomaterials are targeted by a rapidly growing group of nanooptics researchers, due to the promise of optical behavior that is difficult or even impossible to create with nanostructures of homogeneous composition. Examples of important areas of interest include coherent coupling, Fano resonances, optical gain, solar energy conversion, photocatalysis, and nonlinear optical interactions. In addition to the coupling interactions, the strong dependence of optical resonances and damping on the size, shape, and composition of the building blocks provides promise that the coupling interactions of hybrid nanomaterials can be controlled and manipulated for a desired outcome. Great challenges remain in reliably synthesizing and characterizing hybrid nanomaterials for nanooptics. In this review, we describe the synthesis, characterization, and applications of hybrid nanomaterials created through plasmon-induced photopolymerization. The work is placed within the broader context of hybrid nanomaterials involving plasmonic metal nanoparticles and molecular materials placed within the length scale of the evanescent field from the metal surface. We specifically review three important applications of free radical photopolymerization to create hybrid nanoparticles: local field probing, photoinduced synthesis of advanced hybrid nanoparticles, and nanophotochemistry. © 2014 IOP Publishing Ltd.

article DOI  
Abstract: The surface quality of plywood coated with resin impregnated papers based on tannin/furfuryl alcohol resins was studied. Several hardeners such as hexamine, paraformaldehyde, formurea and a mixture of formurea and paraformaldehyde were added in small quantities to a mimosa tannin/furfuryl alcohol resin. Papers impregnated with resin based on tannin + furfuryl alcohol + paraformaldehyde, or + formurea were found to yield excellent results in standard water vapour resistance and cross-cut tests. Matrix assisted laser desorption ionization time of flight (MALDI-TOF) mass spectrometry and cross-polarisation-magic angle spinning NMR (CP-MAS C-13 NMR) were used to show coreaction of tannin with furfuryl alcohol and even furfuryl alcohol self condensation under alkaline conditions, as well as coreaction of formaldehyde-yielding compounds such as hexamine with both tannin aromatic rings and the aromatic ring of furfuryl alcohol. Some of the more important oligomers formed were identified by MALDI-TOF.

Vol. 14(12), pp. 2725-2736 
article DOI  
Abstract: The nonlinear properties and the photophysical behavior of two -conjugated chromophores that incorporate an electron-deficient pyrimidine core (A) and -methylenepyrans as terminal donor (D) groups have been thoroughly investigated. Both dipolar and quadrupolar branching strategies are explored and rationalized on the basis of the Frenkel exciton model. Even though a cooperative effect is clearly observed if the dimensionality is increased, the nonlinear optical (NLO) response of this series is moderate if one considers the nature of the D/A couple and the size of the chromophores (as measured by the number of electrons). This effect was attributed to a disruption in the electronic conjugation within the dyes' scaffold for which the geometry deviates from planarity owing to a noticeable twisting of the pyranylidene end-groups. This latter structural parameter also has a strong influence on the excited-state dynamics, which leads to a very efficient fluorescence quenching.

Vol. 102(7), pp. 072903 
article DOI  
Abstract: We report microwave spectroscopy studies of graphene-based polymer-matrix composite materials subject to uniaxial elongation. The samples were prepared via shear mixing under the same thermal processing conditions of amorphous styrene butadiene rubber (SBR) with quartz grains on the order of micrometers in size and/or graphene sheets with thickness 10-20 nm and average lateral size 200 mu m. An important result is the observation of a significant increase (up to 25%) in the effective microwave permittivity of hybridized nanocomposites comprising both quartz and graphene compared to the nanocomposites with quartz only. We suggest that the coating of quartz grains by graphene sheets is the most likely origin of this synergetic effect. In all cases, we also observe that the permittivity spectrum is unaffected by strain up to 8%. By examining the mechanical response, it is shown that the elasticity network of SBR polymer chains is significantly affected in the rubbery state by filling SBR with graphene and quartz particles.

Vol. 2(1), pp. 1-8 
article DOI  
Abstract: In the soil, the metal-organic interactions, including complexation reactions, that occur between Humic Acid (HA) and various cations (Ba2+, Ca2+, Cu2+, and Zn2+) play a key role in the speciation of divalent ions, and therefore in controlling their biological availability, accumulation and mobility. In order to elucidate the mechanism of such reactions, the effect of various divalent salts (BaCl2, CaCl2, CuCl2, and ZnCl2) on the fluorescence and surface charge properties of a commercial HA, were investigated in the present work. The data indicate that in the presence of increasing added salt amount of BaCl2, CaCl2, and ZnCl2, the HA fluorescence intensities decrease linearly and zetapotential magnitude diminished and reached plateau value. However, non-linear marked decrease of the HA fluorescence intensities, and enhanced zeta-potential decrease, were observed in the presence of increasing CuCl2 added salt amount. Further, by decreasing the aqueous phase pH, in the range pH = 10-4, similar decreases of the HA fluorescence intensities and zeta-potential magnitudes, were also observed. It is shown that Cu2+ divalent cations, as compared to Zn2+, Ba2+, and Ca2+ ions, exhibit greater fluorescence quenching ability and complexing capacity of HA macromolecules. The observed fluorescence and surface charge decrease of HA macromolecules, in the presence of divalent cations, result from cation exchange process, and lead to conformational changes of the macromolecule. The fluorescence and zeta potential data indicate that HA macromolecule has different capacities to interact with various metal ions, and the order of divalent cation complexing capacity with HA is found as follows: Cu > Ba > Ca Zn.

Vol. 436(0), pp. 589-598

Abstract: Abstract In order to elucidate the environmental problems arising from the mobility enhancement of metallic contaminants due to the presence of humic acid (HA) in water, transport and retention experiments of HA, in the presence and in the absence of divalent ions Me2+ (Ca2+, Cu2+ and Pb2+), through natural quartz sand (NQS) porous medium, were carried out. The breakthrough curve and the HA adsorbed amount were measured in each experiment, indicating colloid retention was highly dependent on the suspension ionic strength, and the nature of divalent cation present in the aqueous phase. The data show that in the absence of divalent cations, the adsorbed HA amount at solid-water interface was found to increase with increasing the ionic strength, whereas the flow rate does not affect the retained HA amount on quartz sand. Further, in the presence of divalent cations, the adsorbed HA amount was found to be function, not only of the ionic strength, but also to depend on the divalent cation affinity toward the HA macromolecule. Thus, cations having lower affinity for HA, lead to highest adsorbed HA, whereas cations having higher affinity for HA, give the lowest adsorbed HA on the NQS surface. It is shown that the adsorption of HA, or its complex form with divalent cations (HA-Me2+), on the mineral-water interface, is an irreversible process which is limited by the blocking effect.

Abstract: In this tutorial review we intend to give an overview of the potential of NMR spectroscopy, and in particular solid-state NMR, in characterising micelle-templated mesoporous materials. Different topics are covered including the study of formation mechanisms, the characterisation of structures, textures, surfaces and interfaces, functionalisation, dynamic properties and structure-reactivity correlations. Some selected examples illustrate the variety of information provided by this spectroscopy. Particular attention is paid to recent technological and/or methodological developments.

Abstract: Molecules of pluronic P123 template can be efficiently removed from the pores of mesostructured titania by water extraction at various temperatures from ambient to 100 [degree]C. Such soft and green treatment leads to the formation of anatase nanocrystallites in the walls of the mesoporous titania solid even at room temperature.

Vol. 127(3), pp. 1772-1780 
article DOI  
Abstract: This study focuses on the relations between the microstructure and the viscoelastic behavior of an industrial solid propellant belonging to the class of highly filled elastomers. Precisely, the study aims at determining the impact on the viscoelastic behavior of the presence of the sol fraction inside the polymer network. The sol fraction is the part of the binder that a good solvent can extract. The solid propellant is swollen to various extents by solutions of plasticizer and polymer molecules. This swelling leads to a hydrostatic deformation of the polymer network, corresponding to an extension or contraction loading for each specimen. Prestrained dynamic mechanical analysis tests, superimposing a small oscillating strain on a prestrain, characterize the viscoelastic behavior. The degree of swelling of the network and the effective filler fraction drive the viscoelastic response. In addition, the mechanical behavior does not depend on the chemical nature of the introduced sol fraction. Moreover, a nonlinear behavior, i.e., an increase in both storage and loss moduli with increasing prestrain, is initiated at low prestrain. This nonlinearity depends on the contraction or extension of the network and could result from particles aligning with prestrain, which is expected in such highly filled materials.

article DOI URL 
Abstract: Chemo-mechanotransduction, the way by which mechanical forces are transformed into chemical signals, plays a fundamental role in many biological processes. The first step of mechanotransduction often relies on exposure, under stretching, of cryptic sites buried in adhesion proteins. Likewise, here we report the first example of synthetic surfaces allowing for specific and fully reversible adhesion of proteins or cells promoted by mechanical action. Silicone sheets are first plasma treated and then functionalized by grafting sequentially under stretching poly(ethylene glycol) (PEG) chains and biotin or arginine-glycine-aspartic acid (RGD) peptides. At unstretched position, these ligands are not accessible for their receptors. Under a mechanical deformation, the surface becomes specifically interactive to streptavidin, biotin antibodies, or adherent for cells, the interactions both for proteins and cells being fully reversible by stretching/unstretching, revealing a reversible exposure process of the ligands. By varying the degree of stretching, the amount of interacting proteins can be varied continuously.

Vol. 197, pp. 25-29 
article DOI  
Abstract: Herein, the hydrophobic recovery of argon plasma treated polydimethylsiloxane surfaces is explored. In contrast to previous works, environmental contamination is here taken into account. We find that diffusion and reorientation strongly dominate the hydrophobic recovery under high thermal activation (60 degrees C), no matter the surrounding environment during storage. However, at lower temperature (24 degrees C and below), we find that contamination plays a major role in lab atmosphere environment. By working at low temperature and under inert nitrogen atmosphere to slow down the diffusion and reorientation dynamics and to avoid contamination, we identify two different temperature-dependent regimes in the kinetics of the hydrophobic recovery. One is fast and involves exclusively relaxation processes occurring in the surface region. The second, much slower, concerns diffusion phenomena in the sub-surface region. Thereby, the specific impact of bulk diffusion and surface reorientation processes can be distinguished during aging by slowing down the surface dynamics and by eliminating all possible sources of contamination.

Vol. 270Applied Surface Science, pp. 64-76 
article URL 
Abstract: We propose a simple method to elaborate a filler-free stretchable PDMS surface strong enough to resist to successive elongation/retraction cycles even at high degree of stretching. It consists in creating free radicals on a filler-containing PDMS surface by argon plasma exposure and reacting them with a filler-free PDMS resin during the crosslinking step. Changes of physical and chemical properties upon plasma modification are monitored by FTIR and XPS spectroscopies, contact angle measurements and atomic force microscopy. Electron spin resonance (ESR) is used to identify the nature of radicals involved in interfacial bonding. Although a brittle silica-like layer is created on the filler-containing PDMS surface after plasma treatment, an increase in the PDMS/PDMS interfacial strength is observed and a high interfacial resistance has been found under elongation/retraction (stretching/relaxation) cycles.

Vol. 34(12), pp. 2991-3001 
article URL 
Abstract: We have recently demonstrated strong nuclear deformation of SaOs-2 osteosarcoma cells on poly-l-lactic acid (PLLA) micropillar substrates. In the present study, we first demonstrated that chemical and mechanical properties of the micropillar substrates have no dominant effect on deformation. However, SaOs-2 nucleus deformation could be strongly modulated by varying the pillar size and spacing, highlighting the importance of geometric constraints for shaping the nucleus. Furthermore, comparing the capacity for nuclear deformation in three different osteosarcoma cell lines (SaOs-2, MG-63 and OHS-4) revealed strong cell-type specific differences. Surprisingly, the highly-deformable SaOs-2 cell line displayed the highest cell stiffness as assessed by AFM-based colloidal force spectroscopy and featured a more prominent array of actin fibres above the nucleus, suggesting a link between actin-mediated cell stiffness and cell nucleus deformation. In contrast, in MG-63 and OHS-4 cells dense microtubule and vimentin networks seem to facilitate some nuclear deformation even in the absence of a prominent actin cytoskeleton. Together these results suggest that an interaction of all three cytoskeletal elements is needed for efficient nuclear deformation. In conclusion, the dominant parameters influencing nuclear deformation on micropillar substrates are not their material properties but the substrate geometry together with cell phenotype and cytoskeleton organization.

article DOI  
Abstract: The microstructuring of titania based sol-gel films is investigated by direct writing with a continuous wave ultraviolet laser beam emitting at 244 nm. Depending on the exposure conditions, the films exhibit a volume expansion, a volume shrinkage, a self-shaped delamination, or are damaged. This paper is mainly focused on the regime where spontaneous local delamination occurs, which corresponds to a narrow range of laser irradiances and writing speeds. In this regime, self-organized round-shape micro-holes opened on the substrate are generated. (C) 2013 AIP Publishing LLC.

Vol. 15(8), pp. 2191-2199 
article URL 
Abstract: A green chemistry approach was successfully used in this work to synthesize manganese oxide nanoparticles with different shapes and crystalline phases. This approach is based on the visible light irradiation (445 nm) at room temperature of an aqueous solution of a manganese(ii) salt in the presence of an alkaline hydroxide (NaOH, KOH or LiOH). Several experimental parameters, i.e., the nature of the precursor salt, hydroxide concentration, hydroxide type, irradiation time and the atmosphere, were tuned and their influence on the morphology and the structure of the nanoparticles was studied by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. A diversity of manganese oxide phases ([small lambda]-MnO2, [gamma]-Mn3O4 and MnO(OH)) were obtained. It must be emphasized that these compounds were easily and fairly quickly synthesized at room temperature, without surfactants and, moreover, by using an environmentally friendly method. In addition, the successful control of the size and the shape of the nanoparticles allowed to obtain a variety of nanoparticles morphologies ranging from one-dimensional (1-D) to three-dimensional (3-D) nanostructures (i.e., spherical, nanorods, nanoflowers, nanocubes). This synthetic approach could be readily extended to other transition metal oxides.

Abstract: Abstract We report on the improvement of a fabrication method for micro-optics integration on vertical semiconductor laser diodes (VCSELs). Our approach is based on microlens self-writing by the laser beam itself thanks to self-guided Near-Infra-Red photopolymerization. Fabrication conditions have been optimized to control and take benefit of process sensitivity to oxygen quenching and to make possible the study of photo-chemical parameters influence on final tip geometry. The interest of this simple method for fabricating focused-beam VCSELs is finally discussed.

Abstract: Composites films were prepared by the casting method using native cassava starch plasticized with glycerol and 3D or 2D synthetic fillers i.e. Beta zeolite and Na-beidellite type 2:1 phyllosilicate. Special attention was paid to the effect of the filler contents and type on the mechanical and barrier properties. It was shown that films reinforced with lyophilized Beta zeolite presented both high water solubility (WS) and water vapor permeability (WVP) values than the pristine starch whereas an improvement on the WVP was found for composites prepared from Na-beidellite or from non lyophilized Beta zeolite. For the two types of fillers, a drastic increase of the mechanical properties (especially in the Young’s modulus) was observed.

article DOI  
Abstract: The ultimate miniaturization of electronic devices at the atomic scale with single electrons requires controlling the reversible charge storage in a single atom. However, reversible charge storage is difficult to control as usually only one charge state can be stabilized. Here, combining scanning tunneling microscopy (STM) and density functional theory (DFT), we demonstrate that a single silicon dangling bond of a hydrogenated p-type doped Si(100) surface has two stable charge states (neutral and negatively charged) at low temperature (5 K). Reversible charge storage is achieved using a gate electric field between the STM tip and the surface.

Vol. 87(18), pp. 184431 
article DOI  
Abstract: Co2FeAl (CFA) thin films with thickness varying from 10 to 115 nm have been deposited on MgO(001) substrates by magnetron sputtering and then capped by a Ta or Cr layer. X-ray diffraction (XRD) revealed that the cubic [001] CFA axis is normal to the substrate and that all the CFA films exhibit full epitaxial growth. The chemical order varies from the B2 phase to the A2 phase when decreasing the thickness. Magneto-optical Kerr effect (MOKE) and vibrating sample magnetometer (VSM) measurements show that, depending on the field orientation, one- or two-step switchings occur. Moreover, the films present a quadratic MOKE signal increasing with the CFA thickness, due to the increasing chemical order. Ferromagnetic resonance (FMR), MOKE transverse bias initial inverse susceptibility and torque (TBIIST) measurements reveal that the in-plane anisotropy results from the superposition of a uniaxial and of a fourfold symmetry term. The fourfold anisotropy is in accord with the crystal structure of the samples and is correlated to the biaxial strain and to the chemical order present in the films. In addition, a large negative perpendicular uniaxial anisotropy is observed. Frequency and angular dependencies of the ferromagnetic resonance linewidth show two magnon scattering and mosaicity contributions, which depend on the CFA thickness. A Gilbert damping coefficient as low as 0.0011 is found.

Vol. 436, pp. 363-370 
article DOI  
Abstract: In this paper, the imbibition kinetics of model nanoporous substrates is analyzed. The model nanoporous networks were formed by polystyrene microbeads assemblies. Spontaneous imbibition of these structures with sessile droplets was achieved using water/ethanol mixtures of higher wettability than pure water. The lowest concentration of ethanol leading to the spontaneous imbibition was 30%, and the diameter of the microbeads that ranges from similar to 420 nm to similar to 2230 nm. For ethanol concentrations slightly above this threshold value of 30%, the time dependence of the penetration depth was found to follow the expected t(0.5) time dependence. In this low ethanol concentration range, the imbibition rate was shown to decrease as the diameter of the microbeads increases. This result was attributed to the resistive filling of the throats formed around the contact between two beads that increases with the diameter of the microbeads. At constant bead diameter, an acceleration of the fluid progression was observed when increasing the ethanol concentration, i.e. the capillary force. At high ethanol concentrations the penetration no longer followed the t(0.5) dependence, but linear time dependence over the whole life of the droplet. This acceleration of the imbibition rate was attributed to a prewetting of the internal porous structure by the most volatile ethanol component of the mixture that condenses in the throat formed around the contact between two beads.

Abstract: Knowing that a surface or profile can be characterized by numerous roughness parameters, the objective of this investigation was to present a methodology which aims to determine quantitatively and without preconceived opinion the most relevant pair of roughness parameters that describe an abraded surface. The methodology was firstly validated on simulated fractal profiles having different amplitudes and Hölder exponents and it was secondly applied to characterise different worn regions of a retrieved metallic femoral head articulated against an ultra-high molecular weight polyethylene (UHMWPE) acetabular cup containing an embedded metallic fibber into its surface. The methodology consists in combining the recent Bootstrap method with the usual discriminant analysis. It was validated on simulated fractal profiles showing that, among more than 3000 pairs tested, the total amplitude Rt and the fractal dimension Δ is the most relevant pair of roughness parameters; parameters corresponding to the variables modulated in the analytical expression of the fractal function. The application of this methodology on a retrieved metallic femoral head shows that the most relevant pair of parameters for discriminating the different investigated worn regions is the arithmetic roughness parameter Ra paired with the mean peak height Rpm. This methodology finally helps in a better understanding of the scratch mechanism of this orthopedic bearing component.

Abstract: Highly controlled mixed molecular layers are crucial to study the role of material surface chemistry in biointerfaces, such as bacteria and subsequent biofilms interacting with biomaterials. Si lanes with non-nucleophilic functional groups are promising to form self-assembled monolayers (SAMs) due to their low sensitivity to sidereactions. Nevertheless, the real control of surface chemistry, layer structure, and organization has not been determined. Here, we report a comprehensive synthesis and analysis of undecyltrichlorosilane- and 11-bromoundecyltrichlorosilane-based mixed SAMs on silicon substrates. The impact of the experimental conditions on the control of surface chemistry, layer structure, and organization was investigated by combining survey and high-resolution X-ray photoelectron spectroscopy analysis, wettability measurements, and ellipsometry. The most appropriate conditions were first determined for elaborating highly reproducible, but easily made, pure 11-bromoundecyltrichlorosilane SAMs. We have demonstrated that the control is maintained on more complex surfaces, i.e., surfaces revealing various chemical densities, which were obtained with different ratios of undecyltrichlorosilane and 11-bromoundecyltrichlorosilane. The control is also maintained after bromine to amine group conversion via S(N)2 bromine-to-azide reactions. The appropriateness of such highly controlled amino- and methyl-group revealing platforms (NH2-X%/CH3) for biointerface studies was shown by the higher reproducibility of bacterial adhesion on NH2-100%/CH3 SAMs compared to bacterial adhesion on molecular layers of overall similar surface chemistry but less control at the molecular scale.

Tuning InAs Nanowire Density for HEK293 Cell Viability, Adhesion, and Morphology: Perspectives for Nanowire-Based Biosensors 2013 Acs Applied Materials & Interfaces
Vol. 5(21), pp. 10510-10519 
article DOI  
Abstract: Arrays of nanowires (NWs) are currently being established as vehicles for molecule delivery and electrical- and fluorescence-based platforms in the development of biosensors. It is conceivable that NW-based biosensors can be optimized through increased understanding of how the nanotopography influences the interfaced biological material. Using state-of-the-art homogenous NW arrays allow for a systematic investigation of how the broad range of NW densities used by the community influences cells. Here it is demonstrated that indium arsenide NW arrays provide a cell-promoting surface, which affects both cell division and focal adhesion up-regulation. Furthermore, a systematic variation in NW spacing affects both the detailed cell morphology and adhesion properties, where the latter can be predicted based on changes in free-energy states using the proposed theoretical model. As the NW density influences cellular parameters, such as cell size and adhesion tightness, it will be important to take NW density into consideration in the continued development of NW-based platforms for cellular applications, such as molecule delivery and electrical measurements.

Vol. 138(8), pp. 084704 
article DOI  
Abstract: We present a full density-functional-theory study taking into account the van der Waals interactions of a 2D supramolecular network adsorbed on the Si(111)root 3x root 3R30 degrees-boron surface denoted SiB. We show that, contrarily to the previous calculations [B. Baris, V. Luzet, E. Duverger, Ph. Sonnet, F. Palmino, and F. Cherioux, Angew. Chem., Int. Ed. 50, 4094 (2011)] molecule-molecule interactions are attractive, thanks to van der Waals corrections which are essential to describe such systems. We confirm the importance of the substrate effect to achieve the molecular network on the boron doped silicon surface without covalent bond. Our simulated STM images, calculated in the framework of the bSKAN code, give better agreement with the experimental STM images than those obtained by the integrated LDOS calculations within the Tersoff-Hamann approximation. The tungsten tip presence is essential to retrieve three paired lobes as observed experimentally. The observed protrusions arise from the phenyl arms located above silicon adatoms.

Abstract: We report a structural and thermodynamic investigation of the phase behavior of Ga(OH,F)-MIL-53, a gallium-based metal?organic framework (MOF) having the MIL-53 topology containing 0.7 wt % fluorine bonded to the metal. Despite some small structural differences, especially for the hydrated form, the overall physical chemistry behavior of Ga(OH,F)-MIL-53 is very similar to standard fluorine free Ga-MIL-53 material. A combination of in situ X-ray diffraction, in situ Fourier transform infrared spectroscopy, differential scanning calorimetry, and heat capacity measurements allowed us to establish that Ga(OH,F)-MIL-53 under vacuum (i.e., the empty material) exhibits two stable phases: a nonporous narrow-pore (np) phase favored at low temperature and a large-pore (lp) phase favored at high temperature, accompanied by a huge hysteresis effect. Structure determination of the hydrated material Ga(OH,F)-MIL-53_np_H2O obtained after synthesis, activation, and rehydration was also performed. Density functional theory calculations show that it is not a stable structure of Ga(OH,F)-MIL-53 in the absence of adsorbed water molecules. Instead, this hydrated structure is a swollen variant of the np phase, where the flexible framework has expanded to accommodate water molecules.

Abstract: Reaction of condensed (flavonoid) mimosa tannin extracts with concentrated aqueous ammonia has been investigated. For that purpose, catechin was also used as a flavonoid model compound and treated in similar conditions. Solid state CP-MAS 13C NMR and MALDI-ToF spectroscopy studies revealed that, unlike what was recently theorised, amination is not always regioselective and leading to the conversion of one single OH group in C4′ into NH2. In the present study, new reactions have been evidenced, clearly leading to multiamination of several phenolic hydroxyl groups, heterocycle opening, and oligomerisation and cross-linking through the formation of N bridges between flavonoid units.

Abstract: The synthesis of well dispersed cobalt phosphide nanoparticles (NPs) in SBA-15 mesoporous silica by wet impregnation of the molecular cluster [Co4(CO)10(l-dppa)] (1) (dppa = HN(PPh2)2) is described. The thermal activation of the silica impregnated precursor under a H2/N2 (5/95 %) stream at different temperatures to form NPs was studied and it was found that the size of the latter is limited in the 5.5–6.5 nm range by the size of the pores. The obtained materials were characterized by various analytical methods. The porosity and the structure of the mesoporous silica supports were analyzed by N2 adsorption/desorption and small-angle X-ray diffraction. The nanoparticles were characterized by wideangle X-ray diffraction, transmission electron microscopy in conventional and scanning modes, electron tomography, energy-dispersive X-ray spectroscopy, and magnetic measurements. Cobalt phosphide NPs of few nanometers were observed in the pores of SBA-15.

Vol. 15(1), pp. 1335 
article DOI  
Abstract: The synthesis of photosensitive urethane dimethacrylate that contains poly(ethylene oxide) sequence (PEG, M-w: 400), carboxylic and benzophenone moieties, and its characterization by specific methods (H-1 and C-13 NMR, FTIR, UV and electro-spray ionization-mass spectroscopy) are reported. UV curing parameters of this macromer (BP-UDMA) alone and in monomer combinations was evaluated through FTIR spectroscopy and photo-differential scanning calorimetry using 1 wt% 4-(dimethylamino)phenylacetic acid as co-initiator or Irgacure 819 (Irg819). The results show that the photopolymerization rates of the BP-UDMA are higher in the case of Irg819 (R-max(P) : 0.108 s(-1)) due to its synergic action, whereas the degree of conversion of C=C double bond (DC, after 120 s of UV irradiation) is over 77 %. When other co-monomers (non-acid urethane dimethacrylate and silyl urea methacrylate) are incorporated into the formulation, the photopolymerization rate (0.095-0.132 s(-1)) and DC (84.59-79.69 %) varied in reasonable limits. Depending of the photoinitiator type, as well as the monomer composition, the addition of 0.5, 1 and 3 wt% noble metal precursors (AgNO3 and AuBr3) led to the formation of hybrid composites with in situ-synthesized nanoparticles (NPs), where the variations in the intensity of the surface plasmon absorption bands appeared in the range 400-456 nm (Silver) or 500-553 nm (Gold), better results being obtained in the first initiating system. Homogeneous dispersion of nanoparticles into the polymer matrix was evidenced by EDX and TEM analysis, the last proving the existence of nanoparticles with sizes around 10 nm and variable morphologies. X-ray diffraction analysis complemented these results.

Campos, D.M., Soares, G.A. and Anselme, K. Role of culture conditions on in vitro transformation and cellular colonization of biomimetic HA-Col scaffolds 2013 biomatter
Vol. 3(2159-2527), pp. e24922- 
article URL 
Abstract: We have recently developed new 3D hydroxyapatite/collagen (50/50 wt%) scaffolds using a biomimetic synthesis approach. The first in vitro tests performed in static culture showed a limited cell colonization and survival inside the scaffolds. The current study evaluated in dynamic culture the scaffold changes and colonization by human immortalized osteoprogenitor STRO-1A cells. The stability of our scaffolds in the different culture conditions (static, low flow, high flow) was validated by the maintenance of the pore diameter and interconnectivity over 21 d. The colonization and the viability of STRO-1A cells inside the scaffolds were further evaluated on histological sections. It was demonstrated that only the high flow-rate allowed cell survival after 7 d and a complete scaffold colonization. Moreover, the colonization and viability were different in function of the scaffold position inside the perfusion container. The differentiation markers (alkaline phosphatase activity, type I procollagen and osteocalcin synthesis) of STRO-1A cells were analyzed in the culture medium after 7, 14 and 21 d. The low flow-rate increased significantly the three markers compared with static conditions. In contrast, markers were reduced in high flow-rate compared with low flow-rate. To explain this surprising result, we hypothesized that the different molecules were actually adsorbed on the scaffold because of the closed circuit used in the high flow-rate conditions. In summary, this study provides original results on the influence of flow rate but mostly of the circuit used (open/closed) on the structural modifications and cell colonization of collagen-HA scaffolds.

Abstract: In this work we present a novel method for synthesis of aluminosilicate nanotubes: the fluoride route. F-containing imogolite (F-IMO) exhibits an improved crystallization rate and improved yield. The structure of F-IMO was investigated and compared with F-free imogolite (IMO) by means of X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR) confirming imogolite structure. Solid state nuclear magnetic resonance (NMR) analyses show an increased crystallization rate for F-IMO and confirm the incorporation of fluorine ion in the structure.

Vol. 173(0), pp. 147-154 
article URL 
Abstract: Four pure silica zeolites, chabazite (CHA-structure type) and SSZ-23 (STT-structure type) with cage-like structure and silicalite-1 (MFI-structure type) and beta (∗BEA-structure type) with channel structure, were synthesized and fully characterized. Their sorption properties were examined using gravimetric method combined with Grand Canonical Monte Carlo simulations (GCMC). Of particular interest is the large difference in the adsorption rates of n-hexane, p-xylene and acetone observed for these zeosils at 25 °C, 75 °C and 150 °C. As expected, in most cases, a decrease in the adsorption capacity is observed with increasing the molar volume of the used probe molecule and the temperature. An exception is observed for the pure silica CHA-type zeolite due to its small pore size which prevents molecules from entering its porosity. However, at higher temperature, the window size widens slightly and allows n-hexane and acetone, which have kinetic diameter close to the pore opening, to enter easily in chabazite. As a result, for this zeosil, an increase in the adsorption capacity compared to that obtained at 25 °C is observed. All these zeosils are promising for technological uses in car exhaust gas decontamination.

Their catalytic properties were examined in the non-conventional gas-solid reaction requiring a strong acidity. A deeper focus was paid to the difference in activity/selectivity of these zeolites toward the continuous chlorination of aromatics (nitrobenzene and toluene) using trichloroisocyanuric acid (TCCA, C3N3O3Cl3) as chlorination agent.

Vol. 234(0), pp. 66-73 
article URL 
Abstract: Abstract A bi-layer film composed of a thick layer of ZSM-5 zeolite (MFI-structure type) and a thin layer of EMC-2 zeolite (EMT-structure type) was synthesized on aluminum alloys that are used widely in aerospace industry. The bottom MFI layer was obtained by direct hydrothermal synthesis while secondary growth method was used for the top EMC-2 layer. X-ray diffraction (XRD) and scanning electron microscopy (SEM) results revealed that both layers are highly crystallized and uniform with a total film thickness around 22 μm. Nitrogen sorption measurements indicated that ZSM-5 and EMC-1 layers present an accessible porosity. The high micropore volumes lead to considerably good adsorption properties towards pollutants. Such a result was confirmed by the n-hexane sorption capacity of the bi-layer film which is identical to what is expected for a corresponding powder mixture. Adhesion of zeolite films on aluminum substrate was investigated by scratch tests which highlighted a good adhesion between the bottom layer and the support as well as between the two zeolite layers. This bi-layer film is promising for technological uses in molecular decontamination.

Vol. 47(7), pp. 2260-2272 
article URL 
Abstract: One of the major difficulties for the prediction of separation performances in the case of multi-ionic mixtures nanofiltration lies in the description of the concentration polarization phenomenon. Usual models available in literature do not take account of the polarization phenomenon or only describe it cursorily. Very few studies dedicated to the understanding and the specific description of the concentration polarization phenomenon are available in literature and a 2-D multi-ionic model describing the layer heterogeneity along the membrane length has never been proposed yet. The model used in the present work, called Pore and Polarization Transport Model (PPTM), allows an accurate description of the concentration polarization layer occurring during the filtration of multi-ionic solutions by taking account of the radial electromigrative transport in the layer, the turbulence, as well as the axial heterogeneity.

Our characterization approach relies on two powerful and complementary techniques: in situ time-resolved FTIR spectroscopy and ex situ solid-state NMR. As model systems, three silica/surfactant films displaying various degrees of mesostructuration were synthesized using an amphiphilic block copolymer (PEO-b-PPO-b-PEO) via a UV light induced self-assembly process. The key idea is that the hydration state of the hydrophobic PPO chain is expected to be different depending upon whether the sample is amorphous (blend) or mesostructured (segregated). With real-time FTIR experiments, we show that the methyl deformation mode can act as a signature for the PPO microenvironment so as to trace the progressive copolymer self-association throughout the irradiation time. In H-1 solid-state NMR, the dependence of the H-1 chemical shift on the PPO hydration state has been exploited to evidence the extent of mesostructuration.

Vol. 170(0), pp. 346-351 
article URL 
Abstract: The influence of l-lysine, one of the most basic amino acids, and poly(diallyldimethylammonium) (PDADMA) poly(cations) with different molecular weights on the zeolite Y crystal size and porosity was evaluated by using a high-throughput experiment (HTE) approach, allowing the exploration of a wide range of organic compound concentrations under the same experimental conditions. Depending on their nature and molecular weight, the increased concentration of these organic compounds into the synthesis gel gradually delays the crystallization of the zeolite Y. An intermediate molar content of the amino acid (1 l-lysine:9 SiO2) led to slight decrease of the crystallization rate and a significant reduction of the crystal size down to 300 nm. Thus, the l-lysine is assumed to act as a growth inhibitor. The addition of poly(cations) to the synthesis gel results in the creation of silica-rich mesoporous particles forming aggregates. The PDADMA is mainly located in the silica-rich particles and favor their formation along with their mesoporosity. The larger crystal size is attributed to the inhibition of the nucleation process by the poly(cations).

Vol. 15(15), pp. 3009-3015 
article URL 
Abstract: MFI-type materials with a lamellar morphology were successfully synthesized by using mononitrogen surfactants specifically designed by molecular modelling. The mononitrogen surfactants directed the recrystallization of a crystalline layered polysilicate formed in situ, the magadiite, into a zeolite ZSM-5. Moreover, the surfactants allow the preservation of the lamellar shape of the magadiite and inhibit a further growth into one dimension, leading to the formation of zeolite ZSM-5 nanosheets with a thickness comprised between 2 and 3 nm and a Si/Al ratio of 24. This simple approach paves a new way for obtaining zeolite materials of controlled size and shape for specific catalytic applications.

Vol. 174(0), pp. 117-125 
article DOI URL 
Abstract: Abstract Molecular modelling is a growing science which allows to calculate short range forces between zeolite frameworks and organic compounds. By using a steric approach, it is possible to design templates matching closely with an inorganic framework. Herein, the design, synthesis and successful application of several di(azacrown ether) templates to direct the formation of FAU- and EMT-type zeolites are reported. Following a high throughput experiment design, the synthesis gel composition was optimized to obtain well-crystallized materials. Taking into account their respective crystallization rates, their textural and morphological properties were comparable to their counterparts, typically structured by 15-crown-5 and 18-crown-6 ethers. This work is the first step toward a further design of structure- and shape-directing templates, in order to control the properties of FAU- and EMT-type zeolites aiming specific catalytic and separation applications.

Vol. 38(2), pp. 952-965 
article URL 
Abstract: Hydrogen adsorption on porous materials is one of the possible methods proposed for hydrogen storage for transport applications. One way for increasing adsorption at room temperature is the inclusion of metal nanoparticles to increase hydrogen-surface interactions. In this study, ordered mesoporous carbon materials were synthesized by replication of nanostructured mesoporous SBA-15 silica. The combination of different carbon precursors allowed to tailor the textural, structural and chemical properties of the materials. These carbons were used for the synthesis of hybrid nanostructured carbon/palladium materials with different sizes of metal nanoparticles. The hydrogen sorption isotherms were measured at 77 K and 298 K between 0.1 and 8 MPa. Hydrogen storage capacities strongly correlate with the textural properties of the carbon at 77 K. At room temperature, Pd nanoparticles enhance hydrogen storage capacity by reversible formation of hydride PdHx and through the spillover mechanism. The hydrogen uptake depends on the combined influences of metal particle size and of carbon chemical properties. Carbons obtained from sucrose precursors lead to the hybrid materials with the highest storage capacities since they exhibits a large microporous volume and a high density of oxygenated surface groups.

Vol. 128(1), pp. 436-443 
article DOI  
Abstract: Crosslinking reaction of hydroxyl-terminated polybutadiene (HTPB)/isophorone di-isocyanate (IPDI) was monitored by infrared spectroscopy, dynamic mechanical analysis (DMA), swelling measurements, and by relaxation time (T-2) measurements obtained by low-field NMR technique. Chemical reaction monitored by FTIR shows that urethane bonds were predominantly formed throughout the whole reaction period while DMA and swelling became only effective once the three-dimensional network was formed. NMR results allow differentiating between relaxation-processes associated with different fractions of the reactants in the mixture prior to the network formation. The most important finding in this study is that two of the relaxation processes were found to decline whereas a new fraction with a short relaxation time which emerged specifically at an early stage of reaction and progressed along with advancement of the reaction. All results pointed out to a change in the mixture behavior around 30 h of crosslinking reaction at 60 degrees C, reflecting an important restriction in molecules diffusion and mobilities which were attributed to the gel point formation.

Vol. 40(4), pp. 361-373 
article DOI  
Abstract: A series of new-generation synthetic talcs were prepared by varying the hydrothermal synthesis duration from a few hours up to 2 months. Crystallinity and particle size analysis of the synthetic products were evaluated by photon correlation spectroscopy, transmission electron microscopy, differential thermal analysis and unoriented X-ray diffraction, and then analyzed by various spectroscopic methods such as Fourier transformed infrared spectroscopy and solid-state H-1 and Si-29 magic angle spinning nuclear magnetic resonance. The new process for preparing synthetic talcs allows to obtain single-phased particles which after few hours grow heterogeneously and simultaneously in both the c* direction and the (ab) plan. Fine particles, observed for whatever the synthesis duration, lead to the presence of numerous sheet edges surfaces due to particle size which represents the main difference with natural talc. Spectroscopy data show the influence of the fine particles on signals and highlight that synthetic talc characterization is a potential tool for better understanding crystal chemistry of natural talc.

Abstract: Two neutral heteroleptic iridium(III) complexes bearing substituted pyridine 1,2,4-triazoles as the ancillary ligands have been designed and investigated as emitters for PhOLEDs. Interestingly, blue and blue-green devices were obtained with the two complexes. Best devices were obtained with C-1 and reached a maximum brightness of 10,200 cd/m(2), a current efficiency of 4.3 cd/A at an operation voltage of 7.9 V while exhibiting the unusual low turn-on voltage of only 2.8 V. UV-visible absorption and photoluminescence spectroscopy as well as the cyclic voltammetry of the two iridium(III) complexes were also investigated. (C) 2013 Elsevier B.V. All rights reserved.

Vol. 229(0), pp. 239-249 
article URL 
Abstract: Abstract From the 1960s to the 1990s, the large-scale production of banana in the French West Indies required an intensive use of chlorinated pesticides, such as chlordecone (Kepone), resulting in the diffuse contamination of soil and surface waters in the banana-producing areas. For this reason, drinking water plants were equipped with filters containing commercial activated carbons, being one of the challenges to find local adsorbents for the sustainable management of water treatment plants. In this paper, the adsorption of chlordecone (CLD) on activated carbons (ACs) prepared from sugar cane bagasse is studied, aiming to understand the mechanism of CLD adsorption on the AC surface. First, textural, acido-basic and chemical characteristics of the ACs were determined by thermal desorption, X-ray photoelectron and Boëhm studies. Adsorption isotherms of CLD show that the adsorption capacity increases with the amount of carbon and acidic groups at the AC surface whereas basic groups, hydroxyl and ether groups are detrimental to adsorption. The adsorption capacity is maximized at a solution pH level equal to the pHpzc of the considered AC. From Temperature programmed desorption studies, it is proposed that chlordecone adsorption mechanism onto ACs is mainly governed by interaction with carboxylic groups. These results were correlated to molecular modeling studies of CLD interactions with surface functional groups of AC. The models of preferential positions, corresponding to minimal value of association energy, of interactions between CLD and AC functional groups were obtained.

Abstract: Emissions characteristics from the combustion of five date palm residues, DPR, (Date Palm Leaflets, Date Palm Rachis, Date Palm Trunk, Date Stones and fruitstalk prunings) in a laboratory scale furnace were investigated. Release of gaseous products such as CO2, CO, VOC, NOx and SO2 were measured at 600-800 °C. The main goal was to analyze thermal behaviors and gaseous emissions in order to select the most convenient biofuel for an application in domestic boiler installations. Regards to biofuel characteristics, date stone have the highest energy density (11.4 GJ/m3) and the lowest ash content (close to 1.2%). Combustion tests show that among the tested date palm residues, date stone may be the promising biofuel for the design of combustion processing system. However, a special attention to the design of the secondary air supply should be given to prevent high emissions of CO and volatile matters.

Abstract: Abstract This work presents a preliminary study on the energy recovery of two date palm residues (date stone and date rachis) provided from Tunisia. Rachis residues were transformed into pellets while date stones were used as received. Physicochemical characteristics such as ultimate and proximate analyses and calorific values were determined. Date palm residues were combusted in a domestic pellet boiler according to European EN 303-5 standard. High calorific values of both residues as well as combustion efficiencies close to 80% obtained during combustion tests indicate that these residues are a promising alternative to produce renewable energy in Tunisia. Further adjustments (airflow and fuel feed rates) are necessary to improve boiler efficiencies. High air excess were observed and consequently cooled down the fume temperature.

Vol. 101(6), pp. 66002 
article DOI  
Abstract: We theoretically model the manipulation of a nanorod by an atomic force microscope (AFM), aiming at the determination of its sliding or rolling regimes of motion. It is found that, for contact-mode manipulation, rolling requires simultaneous fulfilment of several conditions. Namely, the corrugation of the substrate potential must be sufficiently high to overcome the effects of the particle adhesion to the substrate and to the tip. On the other hand, the corrugation of the tip potential should be relatively low to allow the particle corners to slide against the tip surface as the particle rotates. Furthermore, only sliding is possible if the tip opening angle or its radius of curvature exceed some critical values determined by the geometry of the particle cross-section.

Abstract: Holographic molecularly imprinted polymer films for the use in chemical sensors are obtained in one step through photopolymerization with interfering laser beams. This results in hierarchical structuring at four length scales: micrometer-scale patterning of millimeter- to centimeter- size polymer objects with holographic optical properties, exhibiting nanometer-scale porosity and specific molecular recognition properties at the molecular scale through self-assembly. Specific binding of the target analyte testosterone is measured by diffraction analysis. [GRAPHICS] .

Abstract: In this article, we focus on hypomaturation autosomal-recessive-type amelogenesis imperfecta (type IIA2) and describe 2 new causal Matrix metalloproteinase 20 (MMP20) mutations validated in two unrelated families: a missense mutation p.T130I at the expected homozygous state, and a compound heterozygous mutation having the same mutation combined with a nucleotide deletion, leading to a premature stop codon (p.N120fz*2). We characterized the enamel structure of the latter case using scanning electron microscopy analysis and microanalysis (Energy-dispersive X-ray Spectroscopy, EDX) and confirmed the hypomaturation-type amelogenesis imperfecta as identified in the clinical diagnosis. The mineralized content was slightly decreased, with magnesium substituting for calcium in the crystal structure. The anomalies affected enamel with minimal inter-rod enamel present and apatite crystals perpendicular to the enamel prisms, suggesting a possible new role for MMP20 in enamel formation.

Abstract: Characterized by a regular porosity in terms of pore size and pore network arrangement, ordered mesoporous solids have attracted increasing interest in the last two decades. These materials have been identified as potential candidates for several applications. However, more environmentally friendly and economical synthesis routes of mesoporous silica materials were found to be necessary in order to develop these applications on an industrial scale. Consequently, ecodesign of ordered mesoporous silica has been considerably developed with the objective of optimizing the chemistry and the processing aspects of the material synthesis. In this review, the main strategies developed with this aim are presented and discussed.

The aim of the present study is to investigate the thin film properties of rod coil block copolymer/phenyl-C-61-butyric acid methyl ester (PCBM) blends as a function of the blend weight ratio, using a copolymer which is based on a poly(3-hexylthiophene) (P3HT) rod block and poly(4-vinylpyridine) (P4VP) coil block. Atomic force microscopy, transmission electron microscopy and grazing incidence X-ray diffraction analysis are used to study the influence of PCBM on the copolymer self-assembling. UV-visible absorption and photoluminescence spectroscopies as well as field-effect mobility measurements are performed in order to get further insight into the blend optoelectronic properties. It is found that the block copolymer phase-separated morphology and charge carrier mobilities strongly depend on the PCBM loading and thermal annealing. In particular, the results point out that PCBM enhances the block copolymer microphase separation within a narrow range of the polymer:PCBM weight ratio. In addition, clear evidence for PCBM accumulation within the P4VP domains is found by monitoring the P3HT fluorescence and charge carrier mobilities.

Abstract: Water-dispersible 1-thioglycerol (TG)-capped Mn-doped ZnS quantum dots were prepared in aqueous solution using the nucleation-doping strategy. Using 4% Mn relative to Zn and a Zn(OAc)(2)/Na2S ratio of 0.9, Mn:ZnS nanocrystals with an average diameter of 3.9 +/- 0.5 nm, with pure Mn2+-related photoluminescence (PL) at 585 nm, and with a PL quantum yield of 13.2% were obtained. Transmission electron microscopy, X-ray powder diffraction, electron spin resonance, X-ray photoelectron spectroscopy, UV-visible spectroscopy and spectrofluorometry have been used to characterize the crystal structure, the doping status, and the optical properties of the doped-dots. Folic acid (FA) was linked to TG-capped Mn: ZnS nanocrystals to produce Mn:ZnS@TG-FA nanobioconjugates that were used for targeted in vitro delivery to a human cancer cell line. Folate receptor mediated cellular uptake of FA-functionalized dots is proven via confocal and two-photon imaging.

Influence of Graphite Characteristics on the Electrochemical Performance in Alkylcarbonate LiTFSI Electrolyte for Li-Ion Capacitors and Li-Ion Batteries 2013 Journal of The Electrochemical Society

Abstract: This work presents the influence of some graphite physico-chemical characteristics such as morphology, structure, textural properties, surface functionality and active surface area (ASA) on the electrochemical performance. The reversible and irreversible capacities, SEI formation at different charging rates, cycling ability have been determined using alkylcarbonate based electrolytes containing LiTFSI as main salt. Three families of graphites have been investigated by SEM, XRD, N2 adsorption, Temperature Programmed Desorption (TPD-MS), and their physico-chemical properties have been correlated to some extent to their electrochemical performances. The irreversible capacity at first cycle increases with the active surface area (ASA) and the specific surface area. The applied current density plays an important role in the SEI formation as shown by the reversible and irreversible capacities and the SEM observations. The passivation layer is mainly formed by polymeric species along with inorganic salts such as Li2CO3 or Li alkylcarbonates (ROLi) as revealed by XPS measurements. Nevertheless, very small quantities of LiTFSI degradation compounds have been detected (LiF, SOx) along with a reversible capacity fade.

Vol. 421(0), pp. 34-43 
article URL 
Abstract: Hydrophobic ordered mesoporous silica particles with cage-like pores (SBA-1 type) were prepared through co-condensation of phenyltriethoxysilane (PhTES) and tetraethylorthosilicate (TEOS) at different TEOS/PhTES molar ratios. It is shown that the hydrophobic character of the particles is enhanced by increasing the phenyl loading (decreasing the TEOS/PhTES molar ratio) and that it could be further enhanced by subsequent trimethylsilyl (TMS) grafting on remaining silanol groups (TMS-PhSBA-1 sample). This increase of hydrophobicity has been evidenced on the internal surface (mesoporosity) of the particles using water adsorption and, on the external surface of the particles (in the form of a pellet) using contact angle measurements. Interestingly, a high hysteresis was measured on the most hydrophobic sample (TMS-PhSBA-1), both on its internal surface during high pressure intrusion/extrusion of liquid water and on its external surface using advancing/receding contact angle measurements. This hydrophobic/hydrophilic behavior is explained by surface silanol sites, first shielded by hydrophobic organic moieties and, which subsequently trap water molecules within the porosity or on the external surface after a forced contact with liquid water. The absence of water extrusion (bumper behavior) of this material is then related both to the presence of silanol sites and to the restricted aperture of the cage-like pore morphology.

Vol. 13(4), pp. 2847-2852 
article DOI  
Abstract: Mesoporous SBA-15 silica materials were grafted with trialkylsilyl compounds having short (C-1) and long (C-8) carbon chain and characterized by XRD, N-2 physisorption analysis, Si-29 MAS-NMR and contact angle (CA) measurements. A drastic enhancement of the hydrophobic property after grafting was observed by forced intrusion water; it occurred in two steps and with quite high intrusion pressures (mean values similar to 10 and similar to 15 MPa). The hydrophobic nature of both internal and external surface area was confirmed by Si-29 MAS-NMR and CA measurements, respectively. After contact with water, materials displayed a partial hydrophobic behaviour with uncompleted spontaneous extrusion. The energies absorbed during water intrusion correspond to 4.3 and 6.1 J . g(-1) for C-1 and C-8 grafted species, respectively.

Vol. 13(19), pp. 3827-3831 
article DOI  
Abstract: We propose a microfluidics device whose main functional part consists of a microcapillary produced by the self-rolling of a thin poly(dimethylsiloxane) film. Rolling is caused by inhomogeneous swelling of the film, pre-treated by oxygen plasma, in the vapour of chloroform. The capillaries are integrated with external electrical circuits by co-rolling electrodes and micro-resistors. The local control of temperature in the tubes by Joule heating is illustrated via the rate of an intra-tubular chemiluminescent reaction. The novel tubes with engineered inner structure can find numerous advanced applications such as functional elements of integrated microfluidics circuits.

Vol. 1(21), pp. 3430-3438 
article URL 
Abstract: The study is devoted to the photo-patterning of photopolymers doped with dispersed ZnO quantum dots (QDs). It is checked first that ZnO QDs retain their fluorescence properties upon polymerization of the acrylate monomer mixtures. The photosensitizer (camphorquinone in our work, CQ) plays an important role in the polymerization process. Experimental and theoretical investigations are undertaken to understand the observed differences induced by the addition of a tertiary amine co-initiator species. Indeed, it is shown experimentally that in the presence of a co-initiator, when the maximum of monomer conversion is reached, the concentration of camphorquinone starts to decrease, whereas a new compound that absorbs at 390 nm is produced. It is proposed here on the basis of theoretical calculations that this species is the charge transfer complex [CQ[radical dot]-amine[radical dot]+], which is stabilized in high viscous media. Then, it was shown that the addition of ZnO QDs does not modify the kinetics of polymerization but rather contributes to the enhancement of the refractive index modulation (an increase of 33% is observed) because of their spatial distribution.

Abstract: Laser direct write techniques represent a prospective alternative for engineering a new generation of hybrid biomaterials via the creation of patterns consisting of biological proteins onto practically any type of substrate. In this paper we report on the characterization of fibronectin features obtained onto titanium substrates by UV nanosecond laser transfer. Fourier-transform infrared spectroscopy measurements evidenced no modification in the secondary structure of the post-transferred protein. The molecular weight of the transferred protein was identical to the initial fibronectin, no fragment bands being found in the transferred protein's Western blot migration profile. The presence of the cell-binding domain sequence and the mannose groups within the transferred molecules was revealed by anti-fibronectin monoclonal antibody immunolabelling and FITC-Concanavalin-A staining, respectively. The in vitro tests performed with MC3T3-E1 osteoblast-like cells and Swiss-3T3 fibroblasts showed that the cells' morphology and spreading were strongly influenced by the presence of the fibronectin spots.

Haneda, M., Bonne, M., Duprez, D. and Ozawa, M. Effect of Y-stabilized ZrO2 as support on catalytic performance of Pt for n-butane oxidation 2013 Catalysis Today
Vol. 201, pp. 25-31 
article DOI  
Abstract: The effect of Y-stabilized ZrO2 as support on the Pt dispersion and catalytic activity for the total oxidation of n-butane was investigated. From XRD, TEM and CO chemisorption measurements, Pt particles were found to be well dispersed with a size of ca. 10 nm over the surface of ZrO2 and Y-stabilized ZrO2, when Pt supported catalysts were calcined at 600 degrees C. Although Pt particles supported on ZrO2 were significantly sintered by high temperature calcination above 800 degrees C, no aggregation of Pt particles was observed for Pt/Y-ZrO2. When the catalyst was calcined at higher temperatures, Pt catalysts supported on Y-stabilized ZrO2 showed higher activity than Pt/ZrO2 for the total oxidation of n-butane. The intrinsic activity, expressed in terms of turnover frequency (TOF), increased with the decrease in Pt dispersion, indicating that n-butane oxidation over Pt catalysts supported on Y-stabilized ZrO2 is a structure sensitive reaction. Y2O3 additive plays a role in improving the thermal stability of Pt particles through the metal-support interaction, while it does not alter the catalytic performance of Pt as catalytic active sites.

Vol. 45, pp. 144-149 
article DOI  
Abstract: This paper describes the conditions for contact formation between soft elastic hemispheres and soft elastic substrates micropatterned with pillars. These microstructured substrates were often proposed in the two past decades for the control of adhesion. In this study the hexagonal micropillars are arranged in hexagonal arrays and the width L of the pillars as well as the distance D between the pillars (with L=D for a sample) are both varied from one sample to another in order to keep the overall planar surface fraction of the pillars constant. Additionally, two pillars of heights h=4 mu m and h=16 mu m are considered here. As expected from previous studies different contact morphologies are found as a function of the aspect ratio and the contact pressure. The contact may be formed (i) only at the top of the pillar, (ii) both at the top and between the pillars, or (iii) simultaneously at the top of the pillars and in between the pillars at the centre of the contact for which the pressure is the highest. Unexpectedly it is shown in this last case that the same contact morphology is obtained with the same pressure if the surface pattern aspect ratio L/h is varied homothetically, suggesting a scale invariant behaviour of the contact formation between the hemisphere and the soft elastic micropatterned substrate.

Vol. 305, pp. 204-216 
article DOI  
Abstract: The present work aimed to investigate the potential of acidic ordered mesoporous organosilica SBA-15 with a controlled local environment of the acid sites for applications in acid-catalyzed reactions in hot water, such as cellobiose hydrolysis. The hybrid silica was prepared by condensation of 1,4-bis(triethoxysilyl) benzene. The material was sulfonated using chlorosulfonic acid or 3-mercaptopropyltrimethoxysilane and further oxidized with H2O2 to give Brønsted solid acids, which were fully characterized. Their acidic properties were studied by calorimetry of NH3 adsorption and in the model reaction of gas-phase isopropanol dehydration and compared with the reference acidic sulfonated resin, Amberlyst 15. The introduction of mercaptopropyl organic arms, oxidized by H2O2, did not change the structure of the material, while sulfonation with chlorosulfonic acid led to a less organized solid. In both cases, calorimetry of NH3 adsorption has evidenced the heterogeneity of the acid strength distribution, suggesting the presence of distinct sites of sulfonation, contrary to our expectation. This was supported by XPS analysis. For gas-phase isopropanol dehydration, the solids sulfonated with chlorosulfonic acid exhibited activity equivalent to that of the sulfonated resin, Amberlyst 15, but were less stable due to sulfur species release, assumed to be sulfonated silanols. The acidic organosilicas SBA-15 obtained via H2O2 oxidation of the mercaptopropyl group are less acidic catalysts, showing low activity for gas-phase isopropanol dehydration. However, no sulfur release was observed. The hybrid solid acids were evaluated in a reaction of great interest in the context of the biomass valorization: cellobiose hydrolysis in hot water. The solids were active at 150 C; however, sulfur leaching analysis showed that the reaction proceeds mainly homogeneously, especially for the material acidified with chlorosulfonic acid. A hot washing pretreatment applied to the catalysts containing the sulfonated propyl groups led to a decrease in their hydrolysis activity, but along with an increase in stability, allowing recycling.

Vol. 15(46), pp. 20320-20325 
article URL 
Abstract: Experimental water intrusion-extrusion isotherms were obtained at room temperature on pure silica ITW-type zeolites (ITQ-12 zeosil). The water intrusion is obtained by applying a high hydraulic pressure corresponding to the intrusion step. When the pressure is released, the water extrusion occurs at a similar pressure to that of the intrusion one. Therefore, the "ITW zeosil-water" system behaves like a spring and the phenomenon is reproducible over several cycles. Several characterization techniques have been performed before and after water intrusion-extrusion experiments in order to reveal the presence or the lack of defects after such experiments. Structural modifications at the long range order cannot be observed by XRD analysis after three water intrusion-extrusion cycles. However, solid state NMR spectroscopy provides evidence of the presence of Q3 groups revealing the breaking of some siloxane bridges after the intrusion step. The "ITW zeosil-water" system can restore 100% of the stored energy corresponding to about 8 J g-1.

Vol. 264, pp. 864-871 
article DOI  
Abstract: In order to facilitate its incorporation into a polymer matrix (mostly hydrophobic), calcium carbonate (CaCO3), which is strongly hydrophilic, has to be chemically treated to avoid the formation of aggregates and to improve the compatibility with the polymer. The objective of this study is to analyze, by using contact angle measurements and X-ray photoelectron spectroscopy (XPS), the CaCO3 surface after a chemical surface treatment with ethyltrimethoxysilane (ETMO) and polyphosphoric acid (PPA) in an organic solvent, in order to verify if these molecules are able to interact with the CaCO3 surface, and to propose some hypothesis about the surface grafting mechanism. After several solvent washings were performed to remove all species in excess, contact angle results have pointed out the presence of an organic layer after the chemical treatment of CaCO3 with ETMO and PPA. Based on XPS results, we propose a grafting mechanism of silane and phosphoric acid molecules. Ethyltrimethoxysilane induce an hydrolysis process of the CaCO3 surface which leads to a condensation phenomenon. This Si OH network is adsorbed through hydrogen interactions with some hydroxyl groups. In the case of phosphoric acid, the molecules are adsorbed on carbon atoms through P-O-C bonds formation. This original grafting points out the major role of the solvent nature with CaCO3 surface reactivity. (C) 2012 Elsevier B. V. All rights reserved.

Knoerr, R., Brendlé, J., Lebeau, B. and Demais, H. Preparation of ferric oxide modified diatomite and its application in the remediation of As(III) species from solution 2013 Microporous and Mesoporous Materials
Vol. 169(0), pp. 185-191 
article URL 
Abstract: A new iron oxide-diatomite system was synthesized in one pot by mixing natural diatomite with a ferrous sulfate solution at room temperature. The characterization of the materials (Diatom-Fe) by XRD and chemical analysis revealed that iron (29% w/w) was crystallized under goethite phase (α-FeOOH). Analysis conducted by SEM further highlighted the preferential presence of goethite on the surface of diatomite, which involves hydrogen bonding between diatomite surface silanol groups and ion species. The mechanism of formation of goethite is suggested to occur through the precipitation of ferrous ions by hydroxyls ions followed by the oxidation of the iron species to yield first to lepidocrocite (γ-FeOOH) then goethite that is thermodynamically more stable. Within this mechanism, the contribution of calcium carbonate through its dissolution into hydroxyls species is evidenced by XRD and FTIR analyses. The remediation properties of Diatom-Fe towards arsenite species cations were investigated in batch jar tests for 24 h at auto-equilibrium pH. The materials showed a noticeable higher As (III) sorption capacity (16 mg/g) than the native diatomite (0.5 mg/g). These results can be explained by the strong affinity of arsenites to goethite which is further emphasized by the dispersion of the iron oxide crystals on diatomite surface.

Vol. 140(2-3), pp. 674-682

Abstract: Abstract Mn-doped zinc sulfide (Mn:ZnS) quantum dots stabilized by 3-mercaptopropionic acid (MPA) were synthesized at 100 °C in basic aqueous solution using the nucleation-doping strategy. The optical properties and structure of the obtained Mn:ZnS QDs have been characterized by UV-vis, photoluminescence (PL) and time-resolved PL spectroscopies, transmission electron microscopy (TEM), X-ray diffraction (XRD), and electron spin resonance (ESR). The obtained nearly monodisperse Mn:ZnS@MPA QDs have an average diameter of ca. 2.5 nm and a zinc-blende crystal structure. By varying the base (LiOH, NaOH, KOH, CsOH) used to deprotonate the MPA ligand and adjust the pH of the aqueous solution to 11, the PL emission wavelengths can be tuned within a relatively large optical window, from 567 to 594 nm. The variations of charge density near the surface of the QDs obtained by changing the cation associated to the MPA ligand and of the dopant location in the ZnS host are at the origin of the PL shifts observed. In order to improve the PL emission efficiency, a ZnS shell was subsequently overcoated around the Mn:ZnS core nanocrystals. With ZnS shell growth, the PL emission wavelength was restricted between 570 and 583 nm but PL quantum efficiency of Mn:ZnS/ZnS core/shell QDs increased up to 18.4%.

Labidi, H., Sonnet, P. and Riedel, D. Electronic Control of the Tip-Induced Hopping of an Hexaphenyl-Benzene Molecule Physisorbed on a Bare Si(100) Surface at 9 K 2013 Journal of Physical Chemistry C
Vol. 117(26), pp. 13663-13675 
article DOI  
Abstract: In this work, we show that the hopping directivity of individual hexaphenyl-benzene (HPB) molecules physisorbed along the S-A step edge of a bare Si(100)-2x1 surface can be reversibly controlled with a periodic hopping length. This is achieved by using the tunnel electrons of a low temperature (9 K) scanning tunneling microscope (STM). A statistical analysis of the electronic excitations applied at various positions on the HPB molecule reveals that the hopping process is related to a strong decrease of the tunnel junction conductance. This process is associated with a charge transfer from the silicon surface to the HPB molecule leading to a hopping mechanism that occurs in two sequential steps. The first step of the hopping process involves the formation of an HPB- anion that triggers the molecular motion into a metastable state. The second step is related to the neutralization of the HPB- anion which provokes the manipulation of the molecule to its final steady position. Our experimental data are supported by the calculations of the relaxed molecule using the density functional theory on the Si(100) surface that takes the van der Waals forces interactions into account Additional calculations of the HPB anion orbitals depict the spatial localization of the extra charge inside the HPB molecule and the relative energies of the HPB molecular orbitals. Finally, our study shows that the hopping direction can be optimized by positioning the STM tip at specific locations along the hopping pathway.

Vol. 172(0), pp. 36-43 
article URL 
Abstract: A bi-layer film composed of a thick layer of ZSM-5 zeolite (MFI-structure type) and a thin layer of EMC-1 zeolite (FAU-structure type) was synthesized on aluminum alloys widely used in aerospace industry. The bottom MFI layer was obtained by direct hydrothermal synthesis while secondary growth method was used for the top FAU layer. X-ray diffraction (XRD) and scanning electron microscopy (SEM) results revealed that both layers are highly crystallized, uniform and well-intergrown with a total film thickness around 10 μm. Nitrogen sorption measurements indicated that ZSM-5 and EMC-1 layers present an accessible porosity. The high micropore volumes lead to considerably good adsorption properties towards pollutants. Such a result was confirmed by the n-hexane sorption capacity of the hybrid film which is identical to what is expected for a corresponding powder mixture. Adhesion of zeolite films on aluminum substrate was investigated by scratch tests which highlighted a good adhesion between the bottom layer and the support as well as between the two zeolite layers. The process described in this paper for the formation of a MFI/FAU bi-layer film can be easily extended to other hybrid coating film.

Abstract: Hybrid bi-layered film composed of a thick layer of ZSM-5 zeolite (MFI structure-type) and a thin layer of Beta zeolite (∗BEA structure-type) is synthesized on aluminum alloys widely used in aerospace industry. In the first step, the bottom MFI layer is formed by direct hydrothermal synthesis on aluminum substrates. In the second step, the ZSM-5 film is seeded with zeolite Beta nanocrystals followed by a secondary growth of the ∗BEA layer using two starting gel compositions. Depending on the Si/Al molar ratio of the starting solution, ZSM-12 zeolite can also crystallise as an impurity phase. It is shown that the crystallisation step of the top layer is faster using zeolite Beta seeds. The sorption capacity of the hybrid film determined by nitrogen adsorption-desorption measurements is promising for technological uses in space decontamination.

Nanosized Films Based on Multicharged Small Molecules and Oppositely Charged Polyelectrolytes Obtained by Simultaneous Spray Coating of Interacting Species 2013 Langmuir
Vol. 29(47), pp. 14536-14544 
article DOI  
Abstract: Simultaneous spraying of polyelectrolytes and small multicharged molecules of opposite charges onto a vertical substrate leads to continuous buildups of organic films. Here, we investigate the rules governing the buildup of two such systems: poly(allylamine hydrochloride)/sodium citrate (PAH/citrate) and PAH/sulfated alpha-cyclodextrin (PAH/CD-S). Special attention is paid to the film growth rate as a function of the spraying rate ratio of the two constituents. This parameter was varied by increasing the spraying rate of one of the constituents while maintaining constant that of the other. For PAH/CD-S systems, whatever the constituent (PAH or CD-S) whose spraying rate was kept fixed, the film growth rate first increases and passes through a maximum before decreasing when the spraying rate of the other constituent is increased. For PAH/citrate, the film growth rate reaches a plateau value when the spraying rate of citrate is increased while that of PAH is maintained constant, whereas when the spraying rate of citrate is maintained constant and that of PAH is increased, a behavior similar to that of PAH/CD-S is observed. The composition of PAH/CD-S sprayed films determined by X-ray photoelectron spectroscopy is independent of the spraying rate ratio of the two constituents and corresponds to one allylamine for one sulfate group. For PAR/citrate, by increasing the PAR/citrate spraying rate ratio, the carboxylic/nitrogen ratio in the film increases and tends to 1. There is thus always a deficit of carboxylic groups (COO- + COOH) with respect to amines (NH2 + NH3+). Yet, the ratio (COO-/NH3+) is always close to 1, ensuring exact charge compensation. The film morphology determined by atomic force microscopy is granular for PAH/CD-S and is smooth and liquid-like for PAR/citrate. A model based on strong (respectively weak) interactions between PAR and CD-S (respectively citrate) is proposed to explain these features.

Vol. 102(16), pp. 163305 
article DOI  
Abstract: When conventional field-effect transistors with short channel length suffer from non-saturated output characteristics, this work proposed a vertical channel transistor to operate like a solid-state vacuum tube and exhibit good saturated curves. We utilized deep ultra-violet interference lithography to produce ordered grid-like metal to control the potential profile in vertical channel. We compared experimental and simulated characteristics to investigate the keys to achieve saturation. Finally, with an optimized design, a vertical organic transistor is used to drive a solution-processed white-light organic light-emitting diode to perform a luminescence control (0-260 cd/m(2)) with a 3.3-V base potential swing.

Vol. 3(39), pp. 17732-17740 
article DOI  
Abstract: A new 100% biosourced thermosetting plastic material, named condensed tannin-furanic thermoset is prepared and characterized in this paper. This new material is synthesized from tannin and furfuryl alcohol, both of which are inexpensive plant-derived chemicals. The co-polymerization process of these two chemicals was studied by C-13 nuclear magnetic resonance (NMR) and matrix-assisted laser desorption-ionization time-of-flight (MALDI-ToF) mass spectroscopy. The 100% renewable bioresourced tannin-furanic thermosetting resin was found to have a glass transition temperature as high as 211 degrees C, and a 95% weight loss temperature of 244 degrees C and 240 degrees C in a nitrogen and in an air atmosphere, respectively. The char yield is as high as 52%. Moreover, this new thermoset material shows excellent mechanical properties: a Brinell hardness of 23 HBS, which is higher than commercial acrylic, polyvinyl chloride, and a little lower than that of solid polystyrene. The compressive break strength was found to be as high as 194.4 MPa, thus higher than that of filled phenolic resins, and much higher than that of solid polystyrene and of acetal resins.

Abstract: This work describes the preparation and characterization of porous 3D-scaffolds based on chitosan (CHI), chitosan/silk fibroin (CHI/SF) and chitosan/silk fibroin/hydroxyapatite (CHI/SF/HA) by freeze drying. The biomaterials were characterized by X-ray diffraction, attenuated total reflection Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, scanning electron microscopy and energy dispersive spectroscopy. In addition, studies of porosity, pore size, contact angle and biological response of SaOs-2osteoblastic cells were performed. The CHI scaffolds have a porosity of 94.2 +/- 0.9%, which is statistically higher than the one presented by CHI/SF/HA scaffolds, 89.7 +/- 2.6%. Although all scaffolds were able to promote adhesion, growth and maintenance of osteogenic differentiation of SaOs-2 cells, the new 3D-scaffold based on CHI/SF/HA showed a significantly higher cell growth at 7 days and 21 days and the level of alkaline phosphatase at 14 and 21 days was statistically superior compared to other tested materials.

Limousy, L., Dutournie, P. and Chevereau-Landais, E. Description of the preferential transport of monovalent salts through Na-mordenite membrane: Physico-chemical aspects 2013 Microporous and Mesoporous Materials
Vol. 167, pp. 133-136 
article DOI  
Abstract: A Na-mordenite membrane was prepared by using sol-gel synthesis protocol, and spin-coating was chosen as the impregnation methodology. The gel was impregnated onto commercial ceramic tubular support (alpha-alumina) and surface characterizations were carried out on Na-mordenite powder prepared with the same gel. The Na-mordenite surface charge is not appreciably modified by a contact with monovalent or divalent salts. The average pore diameter was estimated in the range of 8 nm. Previous results showed that monovalent salts were not retained by the stabilized Na-mordenite membrane while after an alkaline treatment, rejections were observed according to the order of hydration energies (NaF > NaCl > NaBr > NaI). After an acid cleaning, the membrane recovered its initial properties. A new estimation of average pore radius proved that steric effects were not responsible for rejection themselves. A new filtration test of mixed monovalent salt solution was carried out. Fluoride ions were retained by a majority while the others were almost not retained. Infrared characterizations indicate that, after an alkaline treatment, surface chemistry modifications may be at the origin of these interactions. Especially, the apparition of an ultrapolar layer all over the Na-mordenite surface greatly modifies Van der Waals interactions between the hydrated anions and the Na-mordenite surface.

Vol. 107, pp. 323-329 
article DOI  
Abstract: In this present work, energetic characteristics and combustion behavior of agro-pellets, produced from pure spent coffee grounds (SCGs) or blended with pine sawdust in a commercial residential pellet boiler, were examined. Hence, thermal and chemical properties such as calorific value, ash content, bulk density, fixed carbon and elemental analysis obtained from blend and pure biomasses were firstly examined. Moreover, combustion tests were performed in 8-12 kW Okofen Boiler, carbon monoxide (CO) and volatile organic compounds (VOCs) were analyzed according to French standards. The emissions of some gases were also monitored during combustion tests: O-2, CO2, NO and NO2. An Electrical Low Pressure Impactor (ELPI) was used to collect particles from 29 nm to 10 mu m into 12 size fractions to determine mass and number concentrations. The exhaust gaseous and particles emissions of SCG and blend pellets were compared with emissions of wood pellets (DIN + standard). It was found that, despite its high LHV, the use of pure SCG as fuel lead to a lower boiler efficiency, which was followed by an increase of particle and gas emissions. However, when SCG was mixed with pine sawdust (50/50 wt.%), combustion parameters (emissions and boiler efficiency) were very close to those obtained for wood pellets. According to the presented results, although it seems reasonable to consider SCG pellets as a promising alternative fuel, the use of SCG blending up to 50% with pine sawdust is essential to meet French Standards (NF agro-pellets). Hence, this pellets production may be a promising issue for SCG valorisation. (c) 2012 Elsevier Ltd. All rights reserved.

Vol. 25(25), pp. 256007 
article DOI  
Abstract: We report on the first all-epitaxial ferromagnet/inorganic semiconductor/ferromagnet hybrid heterostructure that exhibits (i) a Ge barrier of diamond crystal structure, (ii) room-temperature ferromagnetic electrodes and (iii) very smooth interfaces. Both bottom- and top-Fe-Ge electrodes exhibit tiny in-plane magnetic anisotropies dominated by a magnetocrystalline contribution of six-fold symmetry originating from the hexagonal symmetry of the B8(2) (Ni2In) beta-Fe-Ge phase. A key result is the absence of any magnetic coupling between these soft-magnetic electrodes for Ge barrier thickness as low as similar to 2.5 nm, which allows us to easily tune the parallel and antiparallel magnetic alignments by applying suitably small magnetic fields. This confirms the beneficial use of H-surfactant in order to drastically reduce the roughness of the Ge barrier, as revealed by our scanning tunneling microscopy and transmission electron microscopy measurements. This new all-epitaxial ferromagnet/semiconductor hybrid system appears, therefore, to be a promising candidate for the realization of magnetic tunnel junctions with a single crystal semiconductor barrier that are fully compatible with Si-based technology.

Vol. 114, pp. 81-100 
article DOI  
Abstract: This paper is an attempt to provide a review as extensive as feasible of the literature devoted to the wide variety of sorbent systems that are currently either in use or under laboratory investigation for the removal of the SOx (SO2 + SO3) from flue gases. From an industrial perspective and besides any economic consideration, "the ideal" SOx sorbent candidate must ally four essential qualities some of which may appear contradictory to some extent: a strong affinity of the sorbent towards SO, along with fast kinetics; a large specific surface; a high physical/thermal/chemical stability and the capability for multiple regenerations at a reasonable temperature and with performance recoveries close to 100%. In this paper, the sorbent are classified in four categories which are: (i) single oxides; (ii) mixed oxides (including spinels and alumina supported oxides); (iii) oxides supported on carbonaceous materials and (iv) oxides supported on zeolites and mesoporous materials. A noteworthy outcome of this review lies in the promising prospects offered by porous silica-based materials as desulfurization ("DeSOx") candidates and the interest of elaborating in this direction.

Adsorption of 2,3-DCDD on FAU and EMT-type zeolites: Influence of the nature and the content of charge compensating cations 2013 Microporous and Mesoporous Materials
Vol. 177(0), pp. 25-31 
article URL 
Abstract: Abstract The nature and the content of exchangeable cations in FAU and EMT-type zeolites on the adsorption of dioxin are investigated. These zeolites are selected due to their pore openings, close to the diameter of the 2, 3-dichlorodibenzo-p-dioxin (0.74 nm). In this study, the sodium cations, which balance the negative charge of the zeolitic framework, are replaced by other cationic species such as H+, Mg2+, Li+, Ca2+, K+ and Ag+. The structural and textural analyses performed on the exchanged zeolites indicate that the exchange reaches 70 to 98% and the structure of zeolites is preserved during the exchange process. For both zeolite structure types, the dioxin adsorption rates are the highest for the sodium forms followed by the calcium forms. The following order is obtained: Na+&gt; Ca2+ = Li+&gt; Mg2+= Ag+&gt; K+. It is also noticed that for a same type of zeolite (FAU), the adsorption rate is inversely proportional to the framework Si/Al molar ratio which is related to the content of sodium cations.

Vol. 4(23), pp. 5679-5687 
article URL 
Abstract: Novel push-pull dyes containing a (substituted) hydrocarbon moiety and a malonate (or a malononitrile) moiety are proposed as photoinitiators for the ring opening polymerization of epoxides as well as the synthesis of interpenetrated polymer networks (IPNs) upon exposure to visible light (laser diode, halogen lamp, etc.). Excellent polymerization profiles are obtained. The role of the acceptor and donor moieties in these dyes towards their light absorption properties, the associated photochemical processes and their photoinitiating ability is investigated. A very efficient dye has been selected for the reduction of Ag+ and the in situ formation of Ag(0) nanoparticles in the synthesized IPNs.

Moller-Siegert, J., Parmentier, J., anselme , k. and vix-guterl , C. Mesoporous hydroxyapatite by hard templating of silica and carbon foams for protein release 2013 J.Mater. Sci
Vol. 48(10), pp. 3722-3730 
article DOI  
Abstract: Calcium phosphates, particularly hydroxyapatite Ca10(PO4)6(OH)2 (HA), are widely used for bone regeneration due to their biocompatibility and good resorption properties. However, their performance upon implantation is improved when they are associated with bioactive molecules such as growth factors. Using mesoporous HA leads to improved protein adsorption and release kinetics because the diameter of the mesopores (2–50 nm) is in the same range as their size. We prepared this type of material by the nanocasting method using three different templates: a silica foam and two carbon templates derived from it using propylene or sucrose as carbon source. We investigated the influence of the template, the calcination temperature and of the conditions during template removal. We obtained HA materials with a surface area of up to 90 m2 g−1 and with an intergranular mesopore volume of up to 0.4 cm3 g−1. In this paper, we show for the first time that the synthesis of mesoporous HA from a mesoporous silica foam template allows eliminating the template at lower temperatures (in an alkaline medium), thus preventing the sintering of the HA. These materials have interesting properties for drug delivery applications. The protein adsorption and release capacities of these HAs were tested with two model proteins, bovine serum albumin (BSA), and Cytochrome C. These materials are an important milestone for future bone regeneration systems based on HA associated with human growth factor proteins.

Vol. 58(0), pp. 58-64 
article URL 
Abstract: SCHEMA-SI is an engineering tool able to evaluate the performance of building fire safety system. It uses a dynamic hybrid model, which means that discrete events and continuous phenomena are interconnected at every instant. The model has been developed as a tool to assist fire protection engineers in performing fire safety engineering calculations. This tool may be also used to conduct risk assessments and to evaluate the efficiency of selected design strategies in case of fire in a specific building. Part I of this paper describes SCHEMA-SI tool basis. This paper focuses on a real case study. The case study aims at evaluating and comparing four fire safety strategies in a French hotel.

Abstract: Abstract Two lamellar organosilica films made up of stacks of head-to-head and head-to-tail alkyl bilayers were synthesized by a UV-driven polymerization of n-C18H37SiCl3 and n-C18H37Si(OCH3)3, respectively. In addition to thermogravimetry and small-angle X-ray scattering, the characterization of these multilayer systems was focused on a variety of multinuclear solid-state NMR methods (1H, 29Si, 13C, 2D WISE). The chemical structure of the siloxane interlayer, the alkyl chain conformation and thermal stability were systematically investigated and compared. Through its marked sensitivity to molecular motion, solid-state NMR was used to investigate the effect of interdigitation on alkyl chain dynamics.

Vol. 49Industrial Crops and Products, pp. 851-857 
article URL 
Abstract: Acetylation of mimosa flavonoid tannin is easy to occur but to proceed to completion needs the presence of a catalyst. The acetylated tannin has been shown to be composed of flavonoid oligomers of different levels of acetylation in which the robinetinidin flavonoid unit predominates. All the different OH groups of the flavonoids, both phenolic and alcoholic, are subject to acetylation. Whatever the level of acetylation the acetylated tannin loses its solubility in water and becomes thermoplastic. In the case of the mimosa extract used here the predominance of acetylated B-flavonoid units is exclusively due to the predominance of B-type units, both robinetinidin and catechin, in the original tannin. © 2013 Elsevier B.V.

Vol. 5(14), pp. 6538-6544 
article URL 
Abstract: Silver nanorods (AgNRs) with lengths in the 50-60 nm range were synthesized and functionalized with 2-(2-mercaptoethyl)thioxanthone (C2TX) to generate AgNR@C2TX nanoassemblies. When irradiated at 377 nm in the presence of a diacrylate monomer, these dispersed nanoassemblies initiate radical photopolymerization, indicating that the excited singlet to triplet intersystem crossing process of C2TX in the vicinity of AgNRs was favored while the fluorescence of C2TX was completely quenched at the surface of NRs. SEM and TEM images confirmed the formation of a AgNR-polymer nanocomposite and the homogeneous dispersion of AgNRs in the polymer film. Moreover, under specific experimental conditions allowing the spatial extent of the polymerization to be limited, polymer-capped AgNRs were obtained (polymer diameter of ca. 1 nm).

Abstract: Fully aliphatic segmented poly(ether ester amide) copolymers with uniform hard segments prepared by melt polycondensation of α,ω-hydroxyl end-functionalized polytetrahydrofuran and short glycine or β-alanine bisester-bisoxalamide units hold promise for biomedical applications. For polymers with the hard block contents varying from 10% to 27%, differential scanning calorimetry and atomic force microscopy reveal a highly phase-separated morphology, with ribbon-like nanocrystals dispersed in the soft segment matrix. To relate the polymer properties to the structure of the hard segment, the monomers were prepared and studied by optical and X-ray diffraction measurements. It was shown that the glycine and β-alanine carbonyl ester groups are tilted away from the oxalamide plane, which can affect the degradation rate via hydrolysis of the ester bond.

Abstract: The "ZIF-8-water" system displays reproducible shock-absorber behaviour over several cycles with a stored energy of 13.3 J g-1 and an energy yield close to 85%. The combination of the main features evidenced for ZIF-8, i.e. a quite low intrusion pressure and a high stored energy, opens a field for new applications.

Vol. 87(15), pp. 155421 
article DOI  
Abstract: Scanning tunneling microscopy (STM) studies of the fullerene C-60 molecule adsorbed on the silicon carbide SiC(0001)-3 x 3 surface, combined with density functional theory (DFT) calculations, show that chemisorption of individual C-60 molecules occurs through the formation of one bond to one silicon adatom only in contrast to multiple bond formation on other semiconducting surfaces. We observe three stable adsorption sites with respect to the Si adatoms of the surface unit cell. Comprehensive DFT calculations give different adsorption energies for the three most abundant sites showing that van der Waals forces between the C-60 molecule and the neighboring surface atoms need to be considered. The C-60 molecules are observed to form small clusters even at low coverage indicating the presence of a mobile molecular precursor state and nonnegligible intermolecular interactions.

Abstract: The aim of this study was to analyze the effect of interfacial covalent bonds on the adhesive behavior of an elastomer, a crosslinked polydimethylsiloxane, and a glass substrate. These covalent bonds were created by applying to both materials an appropriate surface treatment by means of plasma polymerization. Adhesion measurements were carried out by analyzing the contact area between a rubber hemisphere and a flat rigid glass plate. The contact was forced under a given compressive loading for different times tc, then the load was removed and the fracture propagation at the interface was recorded as a function of relaxation time tr. Finally, adhesion energies were also determined by means of a probe test using a tensile testing machine.

Abstract: Reactions of 1,3-dimethylimidazol-2-ylidene-borane (diMe-Imd-BH3) and related NHC-boranes with diaryl and diheteroaryl disulfides provide diverse NHC-boryl monosulfides (diMe-Imd-BH2SAr) and NHC-boryl disulfides (diMe-Imd-BH(SAr)(2)). Heating in the dark with 1 equiv of disulfide favors monosulfide formation, while irradiation with 2 equiv disulfide favors disulfide formation. With heteroaryl disulfides, the NHC-borane in the primary NHC-boryl sulfide product migrates from sulfur to nitrogen to give new products with a thioamide substructure. Most substitution reactions are thought to proceed through radical chains in which homolytic substitution of a disulfide by an NHC-boryl radical is a key step. However, with electrophilic disulfides under dark conditions, a competing ionic path may also be possible.

Abstract: Diphenyl disulfide (PhSSPh), a typical boryl monosulfide (diiPr-Imd-BH2SPh) and a typical boryl bis-sulfide [diMe-Imd-BH(SPh)2] all serve as both initiators and precatalysts in the reduction of alkyl and aryl halides by readily available 1,3-dimethylimidazol-2-ylidene⋅borane (diMe-Imd-BH3). The reactions are suggested to occur by a polarity reverse catalysis mechanism where in situ generated thiophenol is the active catalyst.

Vol. 173, pp. 1-5 
article URL 
Abstract: The present work describes the adsorption and separation of xylene isomers by ZIF-8. Although the formal pore diameter of ZIF-8 is much smaller than the molecular diameter of the xylene isomers, ZIF-8 is able to separate the isomers by molecular sieving. A structural study indicates that the diffusion of the xylenes into the pore structure of ZIF-8 happens via a transitory deformation of the pore aperture which is based on a tilt of the imidazolate linkers, followed by a return to the initial conformation. The rate of adsorption depends on the size of the isomer, i.e. it decreases from para- to meta- and to ortho-xylene. The separation of the xylene isomers is good in the gas phase. In liquid phase breakthrough experiments, the quality of the separation is deteriorated. Moreover, as expected for a separation based on molecular sieving, para-xylene cannot be well separated from ethyl-benzene.

Abstract: Turbinaria turbinata brown seaweeds were tested as carbon electrode material in symmetric, electrochemical supercapacitors. The electrochemical properties of the carbon materials were characterised for their application as supercapacitors using cyclic voltammetry, galvanostatic charge/discharge method and electrochemical impedance spectroscopic analyses. Our initial results showed that the optimal behaviour was obtained for the sample prepared by pyrolysis at 800 °C. The average surface area of the carbon was 812 m2/g. Electrochemical tests with an organic electrolyte gave the following interesting results: a capacitance of 74.5 F/g, a specific series resistance of 0.5 Ω cm2 and an ionic resistivity of 1.3 Ω cm2. These results show the promising capacitive properties of carbon derived from seaweeds and their application in electrochemical supercapacitors.

Reinholdt, M.X., Brendle, J., Tuilier, M.-H., Kaliaguine, S. and Ambroise, E. Hydrothermal Synthesis and Characterization of Ni-Al Montmorillonite-Like Phyllosilicates 2013 Nanomaterials
Vol. 3(1), pp. 48-69 
article DOI  
Abstract: This work describes the first hydrothermal synthesis in fluoride medium of Ni-Al montmorillonite-like phyllosilicates, in which the only metallic elements in the octahedral sheet are Ni and Al. X-ray diffraction, chemical analysis, thermogravimetric and differential thermal analysis, scanning electron microscopy and transmission electron microscopy confirm that the synthesized samples are montmorillonite-like phyllosilicates having the expected chemical composition. The specific surface areas of the samples are relatively large (>100 m(2) g(-1)) compared to naturally occurring montmorillonites. Si-29 and Al-27 nuclear magnetic resonance (NMR) indicate substitutions of Al for Si in the tetrahedral sheet. F-19 NMR and Ni K-edge extended X-ray absorption fine structure (EXAFS) local probes highlight a clustering of the metal elements and of the vacancies in the octahedral sheet of the samples. These Ni-Al phyllosilicates exhibit a higher local order than in previously synthesized Zn-Al phyllosilicates. Unlike natural montmorillonites, where the distribution of transition metal cations ensures a charge equilibrium allowing a stability of the framework, synthetic montmorillonites entail clustering and instability of lattice when the content of divalent element in the octahedral sheet exceeds ca. 20%. Synthesis of Ni-Al montmorillonite-like phyllosilicates, was successfully achieved for the first time. These new synthetic materials may find potential applications as catalysts or as materials with magnetic, optical or staining properties.

Vol. 40(5), pp. 411-424 
article DOI  
Abstract: This study is devoted to the physicochemical and mineralogical characterizations of palygorskite from Marrakech High Atlas, Morocco. The raw clay and its Na+-saturated < 2 mu m fraction were characterized using chemical, structural, and thermal analytical techniques. Measurements of specific surface area and porous volume are reported. The clay fraction was found to be made up of 95 % of palygorskite and 5 % of sepiolite. An original feature of this palygorskite is its deficiency in zeolitic H2O. The half-cell structural formula of its dehydrated form was determined on the basis of 21 oxygens to be (Si7.92Al0.08)(Mg2.15Al1.4Fe0.4Ti0.05 )(Ca0.03Na0.08K0.04)O-21, while the hydrated form could be formulated as (Si7.97Al0.03)(Mg2.17Al1.46Fe0.40Ti0.05)(Ca0.03Na0.07K0,03)O-20.18(OH)(1.94)(OH2)(3.88)center dot 2.43 H2O. These formulas show that the (Al3++Fe3+)/Mg2+ ratio is around 0.84, revealing a pronounced dioctahedral character. Further, inside its octahedral sheet, it was determined that the inner M-1 sites are occupied by vacancies, whereas the M-2 sites are shared between 90 % of trivalent cations (78 % for Al3+ and 22 % for Fe3+), 7.5 % of Mg2+, and 2.5 % of Ti4+, all of them linked to 1.94 of structural hydroxyls. The two remaining Mg2+ by half-cell occupy edge M-3 sites and are coordinated to 3.88 molecules of OH2. Channels of this palygorskite are deficient in zeolitic H2O since they contain only 2.43 H2O molecules. A correlation was found between these results and the observation of very intense and well-resolved FTIR bands arising from dioctahedral domains (mainly Al2OH, Fe2OH, and AlFeOH) along with very small responses from a trioctahedral domain (Mg3OH). Accordingly, a schematic representation of the composition of the octahedral sheet was proposed. The cation exchange capacity, specific surface area, and total pore volume were also assessed to be ca. 21.2 meq/100 g, 116 m(2)/g, and 0.458 cm(3)/g, respectively.

Vol. 55(0), pp. 90-97 
article URL 
Abstract: The influence of water on the tribological properties of carbon materials is often explained by the lubricating properties of water. In this study, the interactions between water and the active sites created by the friction, and their influences on the friction coefficient and on the wear are analysed. In order to investigate the chemical reactions under a mechanical stress, experiments were performed under a controlled atmosphere in a planetary ball mill. The chemical reactions between water and graphite were examined by using isotopic labelled water, by doing a chemical balance of the gas phase in the jar and by analysing the surface of the milled material by temperature programmed desorption coupled with mass spectrometry. From the experimental results, a chemisorption mechanism could be proposed to explain how the graphite lubricating properties depend on water. Since the phenomena in the ball mill are similar to those observed with a classical pin-on-disc tribometer, the results obtained could therefore be extrapolated to the graphite behaviour in a conventional tribometer system.

Vol. 67(3), pp. 519-526 
article DOI  
Abstract: Tannin-formaldehyde cryogels (TFC) were synthesized by sol-gel polycondensation of low molecular weight and highly reactive modified tannin with formaldehyde using HCl as a catalyst. Carbon cryogels (CC) were obtained by the TFC pyrolysis at an inert atmosphere at 800 A degrees C. Pyrolysis caused significant changes in the physical and chemical properties of the material. The pyrolysis induced the decomposition of acid superficial groups and the development of basic ones. Pyrolysis also provoked significant change in the pore volume, forming a great amount of micropores. TFC and CC showed amorphous and turbostratic structures, respectively. Unpurified samples had inorganic impurities in their compositions.

Vol. 19(13), pp. 4300-4307 
article DOI  
Abstract: A novel wedge-shaped compound containing two diacetylene tails, namely, methyl 3,5-bis(trideca-2,4-diyn-1yloxyl) benzoate (DDABM), was synthesized. As shown by UV/Vis spectroscopy this compound can be polymerized under UV irradiation. The crystalline structure of DDABM was investigated by grazing-incidence wide-angle X-ray diffraction on oriented crystal-line films deposited on PTFE-rubbed silicon wafer substrates. Furthermore, the spherulites formed in thicker films were analyzed by wide-angle X-ray diffraction. A molecular packing model of DDABM based on the X-ray diffraction data is proposed. The diacetylene units are oriented along a defined lattice direction with a reticular distance of 4.85 angstrom, which fulfills the requirements for topochemical polymerization. It was observed that UV polymerization does not affect the phase behavior of the compound, but mainly alters its optical properties.

Abstract: Radial symmetry is essential for the conventional view of the polymer spherulite microstructure. Typically it is assumed that, in the course of the spherulite morphogenesis, the lamellar crystals grow radially. Using submicron X-ray diffraction, it is shown that in banded spherulites of poly(propylene adipate) the crystals have the shape of a helix with fl at-on crystals winding around a virtual cylinder of about 6 μm in diameter. The helix angle of 30 °?implies that the crystal growth direction is tilted away from the spherulite radius by this angle. The implications of the helical crystal shape contradict the paradigm of the spherulitic microstructure. The radial growth rate of such spherulites does not correspond to the crystal growth rate, but to the propagation rate of the virtual cylinder the ribbons wind around. © 2013 WILEY-VCH Verlag GmbH & Co.

Santa, C.F., Jaber, M., Guth, J.L. and Sierra, L. Synthesis of texturally biphasic mesoporous carbon/silica composites and carbons 2013 Microporous and Mesoporous Materials
Vol. 173, pp. 53-63 
article URL 
Abstract: We report a new synthesis of texturally biphasic carbon/silica composites and carbons that exhibit high surface areas (up to 1500m2g-1), pore volumes (up to 1.9 cm3g-1) and mesopores (4.6-6.9 nm). The composite materials have ordered mesoporous carbon domains embedded in a disordered mesoporous composite carbon/silica phase. This biphasic texture is preserved for the carbons obtained after silica etching. The synthesis involves the addition of tetraethoxysilane (TEOS) into an alkaline triblock copolymer (PEO140PPO39PEO140) aqueous solution, followed by addition of phenol and formaldehyde. The resol/silica composites, obtained after several days under stirring and heating, are pyrolyzed at 500°C or 800°C. TEOS and resin monomers effects on the copolymer self-assembly to form micelles and vesicles were studied by dynamic light scattering (DLS) before flocculation. We propose a formation mechanism, where siliceous species, are localized mainly in micelles outside the vesicles and in the vesicles bilayers, modifying their properties. The hydrophilic resol monomers are absorbed by micelles outside the vesicles as well as by those inside the vesicles core. After flocculation, biphasic materials, with a resol containing phase embedded in a resol-silica composite phase, are obtained. The in situ formation of silica reduces the mesopores shrinking occasioned by pyrolysis in both the hybrid carbon/silica and carbon domains although causes disorder in the pores of the hybrid domain.

Abstract: Self-assembly of conjugated 2,5-dialkoxy-phenylene-thienylene-based oligomers on epitaxial monolayer graphene was studied in ultrahigh vacuum by low-temperature scanning tunneling microscopy (STM). The formation of long one-dimensional (1D) supramolecular chain-like structures has been observed, associated to a physical linking of their ends which involved the rotation of the end thiophene rings in order to allow π?π stacking of these end-groups. dI/dV maps taken at an energy corresponding to the excited states showed a continuous electronic density of states, which tentatively suggests that within such molecular chains conjugation of electrons is preserved even across physically linked molecules. Thus, in a self-organization process conjugation may be extended by appropriately adapting conformations of neighboring molecules. Our STM results on such self-organized end-linked molecules potentially represent a direct visualization of J-aggregates.

Vol. 15(24)Physical Chemistry Chemical Physics, pp. 9670-9678 
article URL 
Abstract: Hybrid materials combining gold nanoparticles (GNP) of variable diameter and an organic thin layer of photochromic diarylethenes were achieved. Solid-state photoswitching based on ring-closure/ring-opening reaction was carried out under alternate UV and visible irradiations. In addition to the spectral changes due to the photochromism itself, the surface plasmon resonance related to the GNP is significantly modified, influenced by a photoinduced change in the refractive index of its environment. These two contributions were sorted out, showing the possibility of probing a photochromic switch by following the plasmon band. The shape change of the plasmon band was consistently compared to calculations based on the Mie theory. Additionally, with one given diarylethene compound, both UV-visible spectroscopy and surface enhanced Raman scattering (SERS) spectroscopy showed an acceleration of the ring-opening photochromic reaction in the presence of GNP. © 2013 the Owner Societies.

Abstract: Chestnut hydrolysable tannins are phenolic materials that have been considered too unreactive to compete in the phenolic resin adhesives market for exterior boards for the building industry. However, an article in 1973 describing 3years industrial application of chestnut hydrolysable tannins during the first oil crisis indicated that this was not the case. We have extended this old work by using superior phenolic resins formulations and producing phenol-formaldehyde-chestnut tannin adhesives where a substitution of up to 80% of the phenol is possible with remarkably good results. The reactions involved were clarified by C-13 NMR and MALDI-TOF mass spectrometry.

Vol. 573, pp. 175-180 
article DOI  
Abstract: The polymerization kinetics of p-xylylene in condensed state was studied by non-isothermal DSC measurements conducted at different heating rates. The total exothermal effect of polymerization reaction (Q=86 +/- 3 kJ mol(-1)) is found to be almost independent from the heating rate. The polymerization temperature spans from -115 degrees C to -80 degrees C at a heating rate of 1 degrees C min(-1) and from 85 degrees C to 30 degrees C at a heating rate of 200 degrees C min(-1). The integral isoconversional method by Vyazovkin and differential isoconversional method by Friedman were applied for the kinetics analysis. Two polymerization regimes have been identified, depending on the heating rate. The effective activation energy exhibits variation with the degree of conversion: it varies from 40 to 65 kJ mol(-1) at low heating rates (1-10 degrees C min(-1)) and from 40 to 24 kJ mol(-1) at high heating rates (20-200 degrees C min(-1)). We suggest that at the low heating rates the polymerization proceeds in the solid state, whereas at the high heating rates it occurs in the liquid state. Atomic force microscopy measurements reveal the effect of polymerization conditions on the surface morphology of the resulting poly(p-xylylene) films. (C) 2013 Elsevier B.V. All rights reserved.

Abstract: This work focuses on the development of a new synthesis route of reducing the number of reactants for the synthesis of phosphate-based materials. Thus one compound, the hexamethylphosphoramide, plays the roles of both precursor of the structure-directing agent (SDA) and the phosphorus source. The influence of some synthesis parameters (heating temperature, nature of solvent, acidity of the medium...) on the in situ decomposition of hexamethylphosphoramide and the results obtained for the gallophosphate system are reported.

Vol. 49(0), pp. 567-574 
article URL 
Abstract: A series of pyridinium salts were synthesized and investigated as new dyes for photoinitiating systems of polymerization. They exhibit a strong absorption at about 550 nm well matching with the visible light emission of different convenient visible light sources. Interestingly, very soft irradiation (halogen lamp) as well as laser diode exposure (457 and 532 nm) can be used. When employed in the presence of a silane and an iodonium salt, they efficiently initiate the free radical polymerization of acrylates and free radical promoted cationic polymerization of epoxides. An acrylate/epoxide blend is also easily polymerized i.e. for the synthesis of interpenetrating polymer networks. In combination with amine, the proposed dyes can also initiate free radical polymerizations. The mechanisms analyzed by ESR and photolysis experiments are discussed for the different multi-component initiating systems.

Vol. 4, pp. 1625-1634 
article URL 
Abstract: New aromatic derivatives PyD based on a pyrene moiety are proposed here as new photoinitiators (PIs) in multi-component systems (with an iodonium salt, a sulfonium salt and optionally a silane) for the radical polymerization of acrylates and the cationic polymerization of epoxy, epoxy-silicone and vinyl ethers. These new photoinitiators allow the use of a long wavelength excitation (using visible light delivered by a halogen lamp, a laser diode at 457 nm or a Xe-Hg lamp). Excellent polymerization profiles are obtained. For polymerization processes using pyrene, very low conversions are reached in agreement with the lack of absorption of this compound for [small lambda] > 380 nm i.e. PyDs are attractive compounds for visible light. Acrylate-epoxide, acrylate-vinyl ether and vinyl ether-epoxide blends are also easily polymerized i.e. for the synthesis of interpenetrating or crosslinked polymer networks. The initiation step mechanisms analyzed by ESR, fluorescence, steady state photolysis and laser flash photolysis experiments are discussed.

Compared to DMPA itself, the lowest electronic transition exhibits a ππ* character and the corresponding molar extinction coefficients ε are increased from about 400 M?1 cm?1 (at about 332 nm for DMPA) to 63?000 M?1 cm?1 (at 338 nm for Tr_DMPA); such huge values are exceptional in Type I photoinitiators at this wavelength. Tr_DMPA undergoes a fast cleavage and efficiently initiate an acrylate polymerization upon a Xe?Hg lamp, a halogen lamp or a laser diode exposure at 405 nm (upon very low light intensities: 2?12 mW/cm2) in the 300?450 nm range. The polymerization of epoxides or divinylethers is also feasible in the presence of an iodonium salt at 405 nm where reference photoinitiators cannot efficiently operate. The chemical mechanisms analyzed by ESR, fluorescence, steady state photolysis, and laser flash photolysis experiments are discussed. A new Type I photoinitiator Tr_DMPA is described.

Abstract: New Type I and Type II photoinitiators based on 2,2-dimethoxy-2-phenylacetophenone (DMPA), benzophenone (BP) and thioxanthone (TX) linked to a pyrene (Py) moiety (Py_DMPA, Py_BP, Py_TX) are proposed here for the free radical polymerization of acrylates and the cationic polymerization of epoxides and vinylethers under a Xe-Hg lamp, laser diode at 405 nm or a halogen lamp. Excellent polymerization profiles using Py_DMPA and Py_BP are obtained, i.e. better than those recorded with the reference compounds (DMPA and BP). Specifically, Py_DMPA and Py_BP absorb in the near UV-visible range (360-420 nm range; absorption red-shift [similar]15 nm), exhibit huge ? values (up to a 90 fold increase) and high photochemical reactivity. The mechanisms analyzed by electron spin resonance, steady state photolysis, fluorescence and laser flash photolysis experiments are discussed for the different initiating systems.

Abstract: Zinc-based metal complexes (ZnC) are proposed as original photoinitiators in multi-component systems for the formation of free radicals under visible light irradiation. The ZnC/iodonium salt/additive three-component systems (where the additive can be a silane or a divinyl ether) present an excellent ability to promote either the free radical polymerization of an acrylate, the cationic polymerization of a divinyl ether and the polymerization of acrylate/vinyl ether blends under very soft irradiations (e.g. halogen lamp irradiation) or laser diodes (457 or 532 nm) exposure. The mechanisms are investigated by photolysis, luminescence and ESR experiments.

Vol. 46(10)Macromolecules, pp. 3761-3770

Abstract: Among other photoinitiating systems, aromatic ketone based compounds have been largely exploited as photoinitiators (PIs). However, none of these compounds efficiently absorb above 420 nm. The search of novel architectures of PIs for getting an important red-shift of the absorption is crucial for the use of visible lights for polymer synthesis. Novel bifunctional dyes derived from the Michler?s ketone structure are proposed here as photoinitiators for the free radical polymerization of acrylates and the cationic polymerization of epoxides upon exposure to 457, 473, and 532 nm laser diodes and even to a green LED bulb at 514 nm. Excellent polymerization profiles are obtained. These original dyes exhibit a push?pull molecular character for a remarkable covering of the visible lights. The formation of the radicals and the ions in the two- and three-component photoinitiating systems is described and the initiation steps are discussed.

Abstract: New perylene-3,4:9,10-bis(dicarboximide) (PBI) photoinitiators/photosensitizers derived from perylene-3,4:9,10-tetracarboxylic dianhydride are synthesized and investigated for the formation of free radicals under air and under very soft irradiation (i.e., halogen lamp) or laser diode exposure at 532 nm. Such a PBI in combination with a diphenyl iodonium salt and N-vinylcarbazole or a silane very efficiently promotes the ring-opening polymerization of epoxides and can also generate acrylate/epoxide interpenetrated polymer networks. It partly behaves as a metal-free organic photocatalyst operating in an oxidative catalytic cycle. The different chemical intermediates are characterized by ESR and laser flash photolysis experiments. The mechanisms involved in the initiation step are discussed.

Abstract: The actual photonitiators PI can only operate in a restricted part of the visible spectrum; as a consequence, several PIs are usually necessary to harvest all the emitted visible photons. In the present paper, new dyes based on a donor?π-acceptor structure (1,3-indanedione derivatives) are incorporated into visible light sensitive photoinitiating systems of polymerization. They exhibit an unusual and remarkable broad absorption lying from the blue to the red. When employed in the presence of an iodonium salt (Iod) and optionally N-vinylcarbazole (NVK), these dyes can efficiently initiate the radical photopolymerization of acrylates, the cationic photopolymerization of epoxide and vinylether monomers and the hybrid cure of acrylate/epoxide blends under exposure, e.g., at 405, 457, 473, 532, and 635 nm. They partly behave as organic photocatalysts. These particular light absorption properties and the initiation step mechanisms are investigated in detail.

Abstract: Truxene-acridine-1,8-dione derivatives (Tr_AD) are proposed as new photoinitiators of polymerization under very soft irradiation (by a household halogen lamp), as well as laser-diode exposure at 405 nm. They exhibit a strong absorption around 380 nm. The Tr_AD/diphenyl iodonium salt/9-vinylcarbazole combination is able to promote the ring-opening polymerization of an epoxide, whereas the Tr_AD/alkyl halide/amine system is very efficient in initiating the radical photopolymerization of an acrylate. Excellent polymerization profiles are obtained. Acrylate/epoxide blends are also easily polymerized. These Tr_ADs in the three-component systems behave as photocatalysts according to oxidative cycles. The mechanisms are discussed for the different multicomponent initiating systems.

Abstract: New thiols for efficient thiol-ene polymerization reactions are presented. They do not exhibit any unpleasant odor, are characterized by quite good light-absorption properties at λ > 300 nm, and generate thiyl radicals upon UV-light exposure. Due to these interesting properties and contrary to many previously reported methodologies, the present thiol-acrylate polymerizations can be efficiently carried out without the presence of any additional photoinitiator. The chemical mechanisms are investigated by steady-state photolysis and electron spion resonance (ESR) experiments. Important parameters can also be extracted from molecular orbital calculations.

Abstract: A series of new dyes based on (thio)barbituric acid derivatives were synthesized and used as photoinitiators of polymerization upon very soft irradiation (laser diodes at 457 nm and 473 nm; blue LED bulbs or even a halogen lamp). These dyes can work according to an oxidative cycle (dye/diphenyl iodonium salt/N-vinylcarbazole system) or a reductive cycle (dye/amine/alkyl halide system) and partly behave as organic photocatalysts. Ring-opening polymerization (ROP) of epoxides and radical polymerization (RP) of acrylates are easily promoted. Excellent RP and/or ROP polymerization profiles are obtained. The contrasting behavior of the thiobarbituric vs. barbituric acid derivative is discussed. The initiation mechanisms, analyzed by Electron Spin Resonance (ESR) and steady state photolysis experiments, are detailed.

Abstract: For polymer synthesis upon visible light, actual photoinitiator operates in a restricted part of the spectrum. As a consequence, several photoinitiators are necessary to harvest all of the emitted visible photons. Herein, 2,7-di-tert-butyldimethyldihydropyrene is used for the first time as a multicolor photoinitiator for the cationic polymerization of epoxides. Upon addition of diphenyliodonium hexafluorophosphate and optionally N-vinylcarbazole, the originality of this approach is to allow efficient monomer conversions under various excitation light sources in the 360-650 nm wavelength range: halogen lamps, and light-emitting and laser diodes. The synthesis of an interpenetrated polymer network from an epoxide/acrylate blend using a red light at 635 nm is also feasible. The formed polymer material exhibits a photochromic character.

Abstract: Novel photoinitiators based on the BODIPY and boranil chromophores being able to photosensitize the iodonium salt decomposition are proposed for the cationic polymerization of epoxy, epoxy-silicone and vinyl ether monomers under exposure to laser diodes at 405, 457, 473 and 532 nm. They allow an interesting tunability of the absorption in the 400-600 nm wavelength range. Quite excellent polymerization profiles are recorded with final conversions up to 90%. Addition of N-vinylcarbazole (NVK) can also greatly enhance the performance. ESR and steady state photolysis experiments show the generation of aryl radicals and cation radicals.

Formation of N-Heterocyclic Carbene-Boryl Radicals through Electrochemical and Photochemical Cleavage of the B-S bond in N-Heterocyclic Carbene-Boryl Sulfides 2013 Journal of the American Chemical Society
Vol. 135(45), pp. 16938-16947 
article DOI  
Abstract: The B-S bond in N-heterocyclic carbene (NHC)-boryl sulfides can be cleaved homolytically to NHC-boryl or NHC-thioboryl and thiyl radicals using light, either directly around 300 nm or with a sensitizer at a longer wavelength (>340 nm). In contrast, the electrochemical reductive cleavage of the B-S bond is difficult. This easy photolytic cleavage makes the NHC-boryl sulfides good type I photopolymerization initiators for the polymerization of acrylates under air.

Vol. 45(0), pp. 162-172 
article DOI URL 
Abstract: The mechanical properties of an acrylate resin and its carbon fiber composite, as well as the adhesion strength between them, were characterized in the case of thermal and electron beam curing (with and without thermal post-cure). It was shown that the properties of the matrix were similar but that the thermal history during the curing had a direct influence on the type of interactions that were generated at the interface, leading to different level of adhesion strength and level of performance for the associated composites. In the case of a thermal cure, the thermal profile allowed the generation of covalent bonding at the interface by thermal degradation of carboxylic acid functionalities and simultaneous production of radicals at the surface of the fiber. A high level of adhesion strength was obtained, which was not the case for electron beam curing without a thermal post-cure at the appropriate temperature.

Vol. 45(3), pp. 722-741 
article DOI URL 
Abstract: A time-dependent oxidation of carbon fibers in boiling nitric acid was used to investigate the influence of a modification of the fiber surface properties on the adhesion strength with an acrylate resin cured by electron beam (EB). For each time of treatment, a characterization of the surface topography and the surface chemistry was done (topography at a micrometric and nanometric scale, specific surface area, temperature programmed desorption, X-ray photoelectron spectroscopy analysis). The oxidation of the fiber surface in boiling nitric acid created a rough surface, which significantly increased the specific surface area, and also generated a high density of hydroxyl groups, carboxylic acids and lactones in comparison to untreated fibers. The adhesion strength with the acrylate resin cured by EB was measured by a pull-out test. For comparison, an isothermal ultraviolet curing of the matrix was also investigated. The value of the interfacial shear strength, determined by the Greszczuk's model, was increased by the oxidation of the carbon fiber surface for both curing processes, but lower values were systemically obtained with EB curing.

Vol. 27(21), pp. 2352-2366 
article DOI  
Abstract: Acrylate functionalities were grafted at the surface of carbon fibers in order to improve the adhesion strength with an acrylate matrix cured by electron beam. An isocyanate bearing aliphatic urethane acrylate was used as a coupling agent. As revealed by X-ray photoelectron spectroscopy, the isocyanate groups reacted with carboxylic acids and hydroxyl groups located at the surface of the fiber, leading to a covalent bonding of the acrylate groups. The adhesion strength was measured by a micromechanical test derived from the pull-out test. A significant improvement of the interfacial shear strength was obtained (+91%) with an electron beam curing. For comparison, an isothermal cure by UV was also investigated and led to the same level of adhesion strength. The improvement was also proved by an increase in the 90° flexural strength of unidirectional composites (+38%). Grafting functionalities that were compatible with the radical mechanism of the polymerization of the matrix appeared to be a promising strategy for the improvement of the mechanical properties of carbon fiber–acrylate composites cured by electron beam.

Abstract: Abstract Thiol functionalities were grafted at the surface of carbon fibers in order to improve the adhesion strength with an acrylate matrix photo-cured by ultraviolet light via a thiol-ene reaction. As revealed by X-ray photoelectron spectroscopy, the grafting was achieved by a reaction between propylene sulfide and the hydroxyl groups located at the surface of the fiber, with the presence of triethylamine. A significant improvement of the interfacial shear strength, measured by a micromechanical test derived from the pull-out test, was obtained (+18%). Generating covalent bonding between the carbon fiber surface and a thermoset polymerizing through a radical mechanism by grafting a chain transfer agent seemed to be an efficient way to improve adhesion strength at the interface.

Vol. -, pp. 9 pages 
article DOI  
Abstract: The photoelectrochemical response and catalytic efficiency towards phenol photooxidation of mesoporous titania particles with spherical morphology have been explored. The catalysts were synthesized in two different arrangements using carbon spheres in a dual role as support and morphology director: hollow spherical titania particles and dense structures where the titania shell is surrounding a carbon core. Although the synthesized titania hollow spheres exhibited a similar photoelectrochemical behavior and optical properties than commercial P25, they showed a better photocatalytic response towards phenol photo-oxidation in terms of pollutant mineralization. This behavior cannot be explained in terms of the crystallinity (found to be higher for P25) and has been attributed to both confinement effects in the mesoporosity of these catalysts as well as to the spherical morphology of titania particles. The spherical arrangement of the titania surface would favor the fast motion of the charge carriers and minimize recombination processes. On the other hand, no clear contribution of the carbon phase to the enhanced photocatalytic response, since quite similar performance is observed for the hollow spheres and the core/shell composite. However, separation and filtration of the catalysts become easier for the carbon/titania composite, thereby improving the so-called practical efficiency.

article DOI URL 
Abstract: Cp2ZrCl2 is presented as both an effective photoinitiator and additive for radical photopolymerization reactions in aerated conditions. This compound is characterized by remarkable properties: (i) an efficiency higher than that of a reference Type I photoinitiator (2,2-dimethoxy-2-phenylacetophenone, DMPA), (ii) an excellent ability, when added to DMPA, to overcome the oxygen inhibition of the polymerization, and (iii) a never reported in situ photoinduced and oxygen-mediated formation of zirconium-based nanoparticles (diameter ranging from 50 to 70 nm). The photochemical properties of Cp2ZrCl2 are investigated by steady state photolysis and electron spin resonance (ESR) experiments. The high reactivity of this compound is ascribed to a bimolecular homolytic substitution SH2 (clearly characterized by molecular orbital calculations) which converts the peroxyls into new polymerization-initiating radicals and oxygenated Zr-based nanoparticles.

Versatile Photochemical Surface Modification of Biopolyester Microfibrous Scaffolds with Photogenerated Silver Nanoparticles for Antibacterial Activity 2013 Advanced Healthcare Materials
Vol. 2(7), pp. 1008-1018 
article URL 
Abstract: A straightforward and versatile method for immobilizing macromolecules and silver nanoparticles on the surface of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) electrospun fibers is developed with the objective of designing a new functional material having significant antibacterial activity. The approach relies on a two-step procedure: UV photografting of poly(methacrylic acid) (PMAA) on the surface of PHBHV fibers according to a “grafting from” method, and complexation of in situ photogenerated silver nanoparticles (Ag NPs) by carboxyl groups from tethered PMAA chains. The photografting process is conducted through a photoinduced free-radical process employing a ketone-based photoinitiator in aqueous medium. Under appropriate conditions, the photogenerated radicals abstract hydrogen atoms from the PHBHV backbone, thus initiating the UV-mediated photopolymerization of MAA from the PHBHV microfibrous surface. The photochemical mechanism of the ketone photolysis is entirely described by the electron spin resonance/spin-trapping technique, and the modified PHBHV microfibrous scaffold is extensively characterized by ATR-FTIR spectroscopy, water contact-angle measurements, and mercury intrusion porosimetry. In a second step, the in situ synthesis of Ag NPs within the microfibrous scaffold is implemented by photoreduction reaction in the presence of both a silver precursor and a photosensitizer. The photoinduced formation of Ag NPs is confirmed by UV spectrophotometry and XPS analysis. SEM and TEM experiments confirm the formation and dispersion of Ag NPs on the surface of the modified fibers. Finally, a primary investigation is conducted to support the antibacterial activity of the new functionalized biomaterial against Staphylococcus aureus and Escherichia coli.

Abstract: A straightforward and versatile method for immobilizing polysaccharides on the surface of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) electrospun fibers is developed with the objective of designing a new functional biomaterial having a significant effect on cell proliferation. The approach relies on a one-step procedure: UV grafting of a photosensitive dextran (AQ-Dext) on the surface of PHBHV fibers according to a "grafting onto" method, with the use of an anthraquinone derivative. The photografting is conducted through a photoinduced free radical process employing an anthraquinone-based photosensitizer in aqueous medium. Under appropriate conditions, AQ-Dext reacts with C-H sigma-bonds of the polymer substrate (PHBHV) to produce a semianthraquinone radical according to an H-abstraction reaction. This radical recombines together with the alkylradical (R-center dot) formed at the surface of PHBHV fibers via the oxygen atom of the anthraquinone photolinker. The photochemical mechanism of the AQ-Dext photolysis is entirely described for the first time by an electron spin resonance technique and laser flash photolysis. The modified PHBHV microfibrous scaffolds are extensively characterized by water contact angle measurements, XPS analysis and atomic force microscopy, confirming the covalent grafting of dextran on PHBHV fibers. Finally, a primary investigation demonstrates that dextran modified PHBHV fibers are permissive for optimized cell colonization and proliferation. The cell morphologies are described by SEM micrographs, revealing a significant affinity and favorable interactions for adherence of human mesenchymal stem cells (hMSCs) on scaffolds provided by dextran chemical structure. Moreover, the proliferation rate of hMSCs increases on this new functionalized biomaterial associated with a higher extra-cellular matrix production after 5 days of culture in comparison with native PHBHV fibers.

Vol. 46(22), pp. 8808-8815 
article DOI  
Abstract: The characterization and the photochemical investigation of a Ru-II complex (Ru(PPh3)(3)Cl-2) having phosphine ligands are reported. DFT calculations and ESR spin trapping experiments revealed for the first time that the photodecomposition of the complex is governed by a homolytic cleavage of the P (C6H5) bond generating phenyl radicals Ph-center dot which are able to initiate the free radical polymerization of acrylate monomers. The addition of a H-donor HD plays a key role in the cationic photopolymerization of epoxides: (i) the reaction efficiency is enhanced using [Ru(PPh3)(3)Cl-2]/HD and (ii) the in situ formation of Ag nanoparticles is observed in the presence of Ru(PPh3)(3)Cl-2/HD/AgSbF6 according to the following reactions: Ph-center dot/DH hydrogen abstraction yielding a D-center dot radical and oxidation of D-center dot by the silver salt.

Vol. 9(3), pp. 765-771 
article URL 
Abstract: In this work, we report on the morphology and stability of water domains growing by condensation on flat chemically micropatterned substrates. The surface pattern consists of hydrophobic hexagonal domains that are distributed following a hexagonal lattice in a hydrophilic continuum. The size and spacing of the hexagons are varied from one sample to the other in such a way as to produce a series of self-similar surface patterns. The size and stability of the water condensation structures growing on these surfaces are investigated in relation to the pattern size and the chemical contrast between the wetted continuum and the non-wetted hydrophobic domains. The water structures that initially grow and spread over the hydrophilic continuum are found to be unstable, collapsing on the hydrophobic domains at a characteristic (normalized) size, which is shown to be independent of the patterns, for a given chemical contrast. This scale invariance of the condensation structures is discussed on the basis of the self-similar variation of the characteristic sizes of the patterns that drive their instability and collapse. Finally, we show that for a high enough chemical contrast, the condensation structure could be tuned into a stable continuum water film that surrounds "dry" spots of non-wetted hydrophobic hexagons.

The P2VP complex forms layers with a liquid-crystalline (LC) order causing phase segregation of the PEO block. The molar ratio ligand/pyridine (x) determines the strength of segregation between the blocks and the microphase morphology. For x >= 0.5, PEO forms cylinders within the LC matrix. The phase separation strongly shifts the crystallization temperature to lower values and forces PEO to crystallize within the block copolymer cylinders. In thin films, alignment of the smectic layers parallel to the substrate induces homeotropic orientation of the PEO cylinders. Inside these cylinders, the crystalline stems preferentially orient along the smectic normal. For x <= 0.33, PEO forms crystalline lamellae within the LC matrix and crystallization dominates the final structure.

Abstract: Cyclometalated PtII complexes that show strong visible-light absorption and long-lived triplet excited states were used as efficient singlet oxygen (1O2) sensitizers for the photooxidation of 1,5-dihydroxynaphthalene (DHN). The photooxidation velocity of the cyclometalated PtII complex is 4.4 times that of the conventional IrIII complex triplet photosensitizers that do not show strong absorption of visible light.

Abstract: Nine different perylene derivatives are prepared and their ability to initiate, when combined with an iodonium salt (and optionally N-vinylcarbazole), a ring-opening cationic photopolymerization of epoxides under very soft halogen lamp irradiation is investigated. One of them is particularly efficient under a red laser diode exposure at 635 nm and belongs now to the very few systems available at this wavelength. The photochemical mechanisms are studied by steady-state photolysis, electron spin resonance spin trapping, fluorescence, cyclic voltammetry, and laser flash photolysis techniques.

Abstract: Anthraquinone derivatives in combination with an iodonium salt (and optionally N-vinylcarbazole) have been used as photoinitiating systems. One of them (Oil Blue N) that is particularly efficient for cationic, IPN, and thiol–ene polymerization upon red lights (laser diode at 635 nm or household red LED bulb at 630 nm) belongs to the very few systems available at this long wavelength in such experimental conditions (low light intensity in the 10–100 mW/cm2 range). Their abilities to initiate the cationic photopolymerization of epoxides or vinyl ethers under very soft halogen lamp irradiation have been also investigated. The photochemical mechanisms are studied by steady state photolysis, fluorescence, cyclic voltammetry, and electron spin resonance spin trapping techniques.

Vol. 54(14), pp. 3458-3466

Abstract: Abstract Seven difunctional acridinediones DAD were prepared and investigated for their abilities to initiate a ring-opening cationic photopolymerization in combination with an iodonium salt (and optionally N-vinylcarbazole) upon UV/visible light (Xe-Hg lamp; &gt;330 nm) or visible light (halogen lamp) exposure. The structural effects in the DADs and the role of the radical cation are outlined. The cationic and radical photopolymerization of an epoxide/acrylate blend in a one-step hybrid cure leads to the formation of an interpenetrated polymer network. The photochemical mechanisms are studied by fluorescence, steady state photolysis, cyclic voltammetry, electron spin resonance spin trapping, and laser flash photolysis techniques.

Abstract: The abilities of two naphthalimide derivatives with a methacryloyl group to initiate, when incorporated in multi-component systems, a ring-opening polymerization of epoxides and a radical polymerization of acrylates under different irradiation sources (e.g. very soft halogen lamp irradiation, laser diode at 457 nm, laser diode at 405 nm and blue LED bulb at 462 nm) have been investigated. One of them is particularly efficient for the cationic and radical photopolymerization of an epoxide/acrylate blend in a one-step hybrid cure and leads to the formation of an interpenetrated polymer network IPN (30 s for getting tack free coatings). The migration stability of one of these naphthalimide derivatives is found to be excellent in the cured polyacrylates and IPNs. The photochemical mechanisms are studied by steady state photolysis, fluorescence, cyclic voltammetry, electron spin resonance spin trapping and laser flash photolysis techniques.

Abstract: [small alpha]-Silicon polyoxomolybdates in combination with an iodonium salt and/or a silane are used to generate phenyl and/or silyl radicals as well as silylium cations upon UV light irradiation. These species can initiate the radical photopolymerization of acrylates, the cationic photopolymerization of epoxides and the photopolymerization of epoxy/acrylate blends (i.e. for the synthesis of interpenetrated polymer networks) thereby leading to the formation of polyoxometalate/polymer hybrid materials. The mechanical properties of e.g. the polyether films are affected by the presence of polyoxometalate in the matrix as shown by their dynamic mechanical analysis (DMA). The photochemical mechanisms are studied by steady state photolysis, cyclic voltammetry, and electron spin resonance techniques.

Abstract: The photoinitiating abilities of indoline and squaraine dyes (D102 and SQ02) incorporated in multicomponent systems for the cationic polymerization of an epoxide or a vinyl ether have been investigated. The polymerizable films exhibit a panchromatic character as revealed by their photosensitivity to a halogen lamp (370?800 nm); household LED bulbs centered at 462 nm (blue), 514 nm (green), 591 nm (yellow), and 630 nm (red); and laser diodes at 457, 473, 532, and 635 nm. SQ02 is particularly efficient in the 520?700 nm range, while D102 exhibits a good efficiency in the 400?580 nm region. The radical photopolymerization of an acrylate can also be observed particularly at 635 nm or upon a halogen lamp. The photochemical mechanisms are studied by steady state photolysis, fluorescence, cyclic voltammetry, electron spin resonance spin trapping, and laser flash photolysis techniques.

Vol. 46(19), pp. 7661-7667 
article DOI  
Abstract: Newly developed benzophenone derivatives in combination with an iodonium salt (and optionally N-vinylcarbazole) or amines have been used as photoinitiating systems. Their abilities to initiate cationic photopolymerization of epoxides and/or radical photopolymerization of acrylates under very soft visible halogen lamp, LED and laser diodes irradiations have been investigated. One of them (BPD5) is particularly efficient for the cationic and radical photopolymerization of an epcocide/acrylate blend in a one-step hybrid cure and leads to the formation of an interpenetrated polymer network IPN upon the house hold blue LED bulb exposure (1 min for getting tack free coatings). The performances attained with some derivatives are better than those obtained with camphorquinone, used as reference photoinitiator, highlighting their high initiating abilities. These systems can be useful to overcome the oxygen inhibition for very low light intensity. The photochemical mechanisms are studied by molecular orbital calculations, fluorescence, cyclic voltammetry, laser flash photolysis, electron spin resonance spin trapping, and steady state photolysis techniques.

Abstract: New photoinitiating systems based on a polyoxometalate (POM) are proposed: phosphomolybdic acid in combination with silane, germane, or iodonium salt can be used to generate silyl, germyl, or phenyl radicals as well as silylium cations. The photochemical mechanisms are studied by steady-state photolysis and electron spin resonance. The phosphomolybdic acid/silane/iodonium salt system can initiate either the radical photopolymerization of acrylates or the cationic photopolymerization of epoxides. The synthesis of interpenetrated polymer networks can also be carried out. The mechanical properties of the synthesized polymers are affected by the presence of POM in the matrix, as shown by their dynamic mechanical analysis (DMA).

Vol. 15(14), pp. 4939-4946 
article DOI  
Abstract: Scanning Tunneling Microscopy (STM), Scanning Tunneling Spectroscopy (STS), and manipulation studies were performed on an ordered self-assembled monolayer (SAM) of N,N'-bis(1-hexylheptyl)perylene-3,4: 9,10-bis(dicarboximide) molecules on epitaxial graphene on hexagonal silicon carbide - SiC(0001). Four novel aspects of the molecular SAM on graphene are presented. Molecules adsorb in both armchair and zig-zag configurations, giving rise to six orientations of the molecular layer with respect to the underlying substrate. The interaction between the molecules and the graphene surface shifts the LUMO towards the Fermi level, inducing a charge transfer and the opening of a band gap in the graphene, with the LUMO inside. This decouples the LUMO from the surface rendering it invisible in the dI/dV spectroscopy. The HOMO only becomes visible at short tip-surface distances, as its energy lies within the band gap of the SiC substrate. Finally, the observed molecular defects are very particular, being composed exclusively of molecular dimers. These molecular dimers have a stronger interaction with the graphene than other molecules.

Vol. 4(1)Beilstein Journal of Nanotechnology, pp. 875-885 
article URL 
Abstract: Ultraflat surface substrates are required to achieve an optimal performance of future optical, electronic, or optoelectronic devices for various applications, because such surfaces reduce the scattering loss of photons, electrons, or both at the surfaces and interfaces. In this paper, we review recent progress toward the realization of ultraflat materials surfaces. First, we review the development of surface-flattening techniques. Second, we briefly review the dressed photon-phonon (DPP), a nanometric quasiparticle that describes the coupled state of a photon, an electron, and a multimode-coherent phonon. Then, we review several recent developments based on DPP-photochemical etching and desorption processes, which have resulted in angstrom-scale flat surfaces. To confirm that the superior flatness of these surfaces that originated from the DPP process, we also review a simplified mathematical model that describes the scale-dependent effects of optical near-fields. Finally, we present the future outlook for these technologies. © 2013 Yatsui et al.

Vol. 607, pp. 111-117 
article DOI  
Abstract: Scanning Tunneling Microscopy (STM) observations of the Si(111) root 13 x root 13-R13.9 degrees-Co surface reconstruction show that two types of clusters coexist on the surface appearing as dark and bright on the images. The atomic structure of the dark ones has been recently proposed by L. Chaput et al. (L. Chaput, F. Dulot, M. C. Hanf, P. Wetzel, Surf. Sci. 604 (2010) 513) [34]. We found that each dark cluster consists of three Co atoms located on substitutional sites of the Si(111) surface with an overlying triangle of six Si adatoms. Here, we present the determination of the bright clusters atomic structure. Combining high-resolution filled and empty-state STM images and DFT simulations, we show that bright clusters consist of additional Si adatoms located on top of the six Si atoms terminating the dark clusters. These Si adatoms are in number of one, two or three. Energy stability of these three configurations and description of the electronic states are discussed in detail. (c) 2012 Elsevier B.V.

Vol. 54(0), pp. 199-214 
article URL 
Abstract: Abstract In a very uncertain and competitive economy, companies have to cope with external constraints such as environmental and social issues, to gain competitive advantage. Over the last thirty years, numerous initiatives have appeared to deal with socio-environmental issues. However, contexts are complex and dynamics. Many authors therefore point out the need to establish a systemic perspective in order to improve the integration of sustainable issues into all company activities: from strategic decision-making to the end of the project. In addition, companies need to reinforce the relationship between general corporate development and eco-design activities. Based on literature review, this paper assumes that the integration of sustainability can be improved by developing a coherent and system approach between strategic, tactical and operational levels. The authors have chosen to demonstrate this assumption by targeting the environmental aspect of sustainability as a first step of their overall research.

Abstract: A novel wedge-shaped amphiphilic molecule bearing a sulfonate group at the tip displays humidity-induced phase transitions from a hexagonal columnar structure to a bicontinuous cubic phase. The mesophases can be frozen by photopolymerization of acrylic end-groups resulting in free-standing membranes with different topology of ionic nanochannels. The obtained membranes with a well-ordered ionic channel structure hold promise for applications in separation and catalysis. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Abstract: The three-dimensional structures of hyperbranched materials have made them attractive in many important applications. However, the preparation of hyperbranched materials remains challenging. The hyperbranched materials from addition polymerization have gained attention, but are still confined to only a low level of branching and often low yield. Moreover, the complication of synthesis only allows a few specialized monomers and inimers to be used. Here we report a 'Vinyl Oligomer Combination' strategy; a versatile approach that overcomes these difficulties and allows facile synthesis of highly branched polymeric materials from readily available multi-vinyl monomers, which have long been considered as formidable starting materials in addition polymerization. We report the alteration of the growth manner of polymerization by controlling the kinetic chain length, together with the manipulation of chain growth conditions, to achieve veritable hyperbranched materials, which possess nearly 70% branch ratios as well as numerous vinyl functional groups. © 2013 Macmillan Publishers Limited.

Vol. 49(86), pp. 10124-10126 
article DOI  
Abstract: In this study, we have managed to find the optimal ATRA system that can obtain the highest mono-adduct yields with the purpose of minimizing the chain growth of divinyl monomers. The most highly hyperbranched polymers have been synthesized by the homopolymerization of multi-vinyl monomers via ATRA reaction.

Abstract: The formation of ultra-small Mg-based particles nanoconfined into the mesopores of a carbon template was studied by in situ synchrotron diffraction. Either Mg2Ni or Mg2NiH4 nanoparticles can be directly formed starting from separate Ni and MgH2 nano-species by tuning the H2 pressure and temperature. Both ultra-small Mg2Ni and Mg2NiH4 nanoparticles (∼4 nm) are extremely stable against coalescence during hydrogen sorption cycling and prolonged exposure to high temperature as compared to Mg and MgH2 nanoparticles that show severe coalescence under same experimental conditions. The structural transition reported in bulk Mg2NiH4 from high temperature cubic to low temperature monoclinic structure is no longer observed for the nanoconfined particles. Hydrogen absorption/desorption in nanosized Mg2Ni is reversible and sorption kinetics proceed very quickly (∼5 min) even at 483 K. On the contrary, the thermodynamics properties are not altered by nanoconfinement. This study opens new routes for successful nanoconfinement of stoichiometric hydrides into the pores of carbon hosts along with a better understanding of the underlying nanochemistry.
