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.

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

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.

Vol. 653, pp. 32-42

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.
