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

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

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

Vol. 35, pp. 146-152 
article DOI URL 
Abstract: Nonwovens of polymer/clay composite nanofibers (namely, polyacrylonitrile/Na-montmorillonite, PAN/Na-MMT) are produced by electrospinning a solution of PAN in dimethylformamide containing synthetic Na-MMT. The influence of both Na-MMT amount and applied voltage on the properties of electrospun composite nonwovens was studied. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA-DTA) were used to evaluate the morphology, structure and thermal properties of composite nanofibers. SEM observations revealed that increasing the amount of Na-MMT in the solution or the applied voltage increases the average diameter of electrospun composite nanofibers. The prepared composite showed a higher thermal stability that the pristine PAN nanofibers. It was proven that the ion exchange properties of Na-MMT were maintained in the obtained composite. © 2015 The Korean Society of Industrial and Engineering Chemistry.

Aristilde, L., Lanson, B., Miehe-Brendle, J., Marichal, C. and Charlet, L. Enhanced interlayer trapping of a tetracycline antibiotic within montmorillonite layers in the presence of Ca and Mg 2016 Journal of Colloid and Interface Science
Vol. 464, pp. 153-159 
article DOI  
Abstract: The formation of a ternary antibiotic metal clay complex is hypothesized as the primary adsorption mechanism responsible for the increased adsorption of tetracycline antibiotics on smectites in the presence of divalent metal cations under circumneutral and higher pH conditions. To evaluate this hypothesis, we conducted a spectroscopic investigation of oxytetracycline (OTC) interacting with Na-montmorillonite in the presence and absence of Ca or Mg salts at pH 6 and pH 8. Despite a twofold increase in OTC adsorbed in the presence of Ca or Mg, both solid-state nuclear magnetic resonance and infrared signatures of the OTC functional groups involved in metal complexation implied that the formation of an inner-sphere ternary complexation was not significant in stabilizing the adsorbate structures. The spectroscopic data further indicated that the positively-charged amino group mediated the OTC adsorption both in the absence and presence of the divalent metal cations. Focusing on the experiments with Mg, X-ray diffraction analysis revealed that the metal-promoted adsorption was coupled with an increased intercalation of OTC within the montmorillonite layers. The resulting interstratified clay layers were characterized by simulating X-ray diffraction of theoretical stacking compositions using molecular dynamics-optimized montmorillonite layers with and without OTC. The simulations uncovered the evolution of segregated interstratification patterns that demonstrated how increased access to smectite interlayers in the presence of the divalent metal cations enhanced adsorption of OTC. Our findings suggest that specific aqueous structures of the clay crystallites in response to the co-presence of Mg and OTC in solution served as precursors to the interlayer trapping of the antibiotic species. Elucidation of these structures is needed for further insights on how aqueous chemistry influences the role of smectite clay minerals in trapping organic molecules in natural and engineered soil particles.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Vol. 15, pp. 576-582 
article DOI URL 
Abstract: Despite kerogen’s importance as the organic backbone for hydrocarbon production from source rocks such as gas shale, the interplay between kerogen’s chemistry, morphology and mechanics remains unexplored. As the environmental impact of shale gas rises, identifying functional relations between its geochemical, transport, elastic and fracture properties from realistic molecular models of kerogens becomes all the more important. Here, by using a hybrid experimental–simulation method, we propose a panel of realistic molecular models of mature and immature kerogens that provide a detailed picture of kerogen’s nanostructure without considering the presence of clays and other minerals in shales. We probe the models’ strengths and limitations, and show that they predict essential features amenable to experimental validation, including pore distribution, vibrational density of states and stiffness. We also show that kerogen’s maturation, which manifests itself as an increase in the sp2/sp3 hybridization ratio, entails a crossover from plastic-to-brittle rupture mechanisms. © 2016 Nature Publishing Group

Vol. 32(10), pp. 1226-1234

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

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

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

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

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

Vol. 10(3), pp. 261-268 
article DOI  
Abstract: The continuous photopolymerization of acrylate and methacrylate monomer miniemulsions (25% solids content) is investigated at room temperature in a compact helix minireactor. Using n-butyl acrylate, the process yields 95% conversion after only 27 s residence time, and gel-free high-molecular-weight products. Under optimized conditions, a 25-fold increase in efficiency is obtained when compared to a batch photopolymerization. The reaction set-up offers a frugal process because of moderate irradiance (2.6 mW cm(-2)), photoinitiator concentration (0.75 wt%), and low-power UV-A fluorescent lamp.

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

Vol. 329, pp. 77-87 
article URL 
Abstract: Abstract Two different groups of methacrylates containing Type I or Type II photoinitiating moieties were synthesized and evaluated for use in UV curing applications. The first, a novel group of monomeric photoinitiators (MPIs) were synthesized by reactions of tert-butyl α-bromomethacrylate (TBBr) with 2-hydroxy-1-[4-(2-hydroxyethoxy)phenyl]-2-methyl-1-propanone (Irgacure 2959), 1-hydroxy-cyclohexyl-phenyl-ketone (Irgacure 184) and 4-hydroxyacetophenone to give monomers MPI1, MPI3 and MPI4 respectively; and conversion of MPI1 to MPI2 by cleavage of tert-butyl ester groups with trifluoroacetic acid. The second group of photoinitiators were synthesized by reaction of 2-isocyanatoethyl methacrylate (IEM) with Irgacure 2959 (MPI5) and 4-hydroxybenzophenone (MPI6). All these MPIs’ absorption range in the UV region was found to be similar to their nonmonomeric analogs. Their photoinitiating abilities in the polymerizations of hexane-1,6-diol diacrylate (HDDA), 2-hydroxyethyl methacrylate (HEMA) and trimethylolpropane triacrylate (TMPTA) were studied using photodifferential scanning calorimeter and the kinetic parameters were correlated with the structures of the photoinitiating systems. Photoinitiating activities of investigated Type I photoinitiators, including small molecule commercial analogs, during polymerizations of HDDA and TMPTA are very slightly influenced by MPIs structure. However, the MPI structure is found to be important for the curing of HEMA, and some of the synthesized MPIs have better efficiency than commercial ones tested. The MPIs based on Irgacure 2959, Irgacure 184 and benzophenone (BP), with similar or increased photoinitiating activity compared to their commercial precursors, appear to be promising photoinitiators. An extra advantage of MPIs is their incorporation into the final formulations, reducing undesired migration of small molecules.

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

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

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

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

Vol. 49(9), pp. 1980-1989 
article DOI URL 
Abstract: ConspectusPhotoinitiated polymerization has been the subject of continued research efforts due to the numerous applications in which this polymerization technique is involved (coatings, inks, adhesives, optoelectronic, laser imaging, stereolithography, nanotechnology, etc.). More recently, photopolymerization has received renewed interest due to the emergence of 3D-printing technologies. However, despite current academic and industrial interest in photopolymerization methodologies, a major limitation lies in the slow rates of photopolymerization. The development of new photoinitiating systems aimed at addressing this limitation is an active area of research. Photopolymerization occurs through the exposure of a curable formulation to light, generating radical and/or cationic species to initiate polymerization. At present, photopolymerization is facing numerous challenges related to safety, economic and ecological concerns. Furthermore, practical considerations such as the curing depth and the competition for light absorption between the chromophores and other species in the formulation are key parameters drastically affecting the photopolymerization process. To address these issues, photoinitiating systems operating under low intensity visible light irradiation, in the absence of solvents are highly sought after.In this context, the use of photoredox catalysis can be highly advantageous; that is, photoredox catalysts can provide high reactivities with low catalyst loading, permitting access to high performance photoinitiating systems. However, to act as efficient photoredox catalysts, specific criteria have to be fulfilled. A strong absorption over the visible range, an ability to easily oxidize or reduce as well as sufficient photochemical stability are basic prerequisites to make these molecules desirable candidates for photoredox catalysis. Considering the similarity of requirements between organic electronics and photopolymerization, numerous materials initially designed for applications in organic electronics have been revisited in the context of photopolymerization. Organic electronics is a branch of electronics and materials science focusing on the development of semiconductors devoted to three main research fields; organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic solar cells (OSCs). The contribution of organic electronics to the field of electronics is important as it paves the way toward cheaper, lighter, and more energy efficient devices. In the present context of photopolymerization, materials that were investigated as photocatalysts were indifferently organic semiconductors used for transistors, charge-transport materials, and light-emitting materials used in electroluminescent devices or conjugated polymers and small molecule dyes for solar cells. In this Account, we summarize our latest developments in elaborating on photocatalytic systems based on these new classes of compounds. Through an in-depth understanding of the parameters governing their reactivities and our efforts to incorporate these materials into photoinitiating systems, we provide new knowledge and a valuable insight for future prospects. © 2016 American Chemical Society.

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

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

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

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

Eren, T., Okte, N., Morlet-Savary, F., Fouassier, J., Lalevee, J. and Avci, D. One-component thioxanthone-based polymeric photoinitiators 2016 Journal of Polymer Science, Part A: Polymer Chemistry
Vol. 54(20), pp. 3370-3378

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

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

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

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

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

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

Vol. 181, pp. 379-388 
article URL 
Abstract: Abstract In this study, copper oxide (CuO) has been dispersed into an organized mesoporous silica (SBA-15) using the solid state grinding method. The resulting CuO/SBA-15 materials were evaluated as SOx adsorbents and were fully characterized before and after sulfation. The influence of the calcination conditions on the copper dispersion was studied. Results show that the textural properties of the materials and the formed copper species are closely related to the calcination procedure. The adsorption performances increase with the copper dispersion. It was found that despite the high GHSV value used in this work (25,000 h−1), the highly dispersed copper species confer a high efficiency to the adsorbent. Cyclic adsorption/regeneration experiments show a surprising but explainable increase in the adsorption efficiency in the second cycle followed by a slight but monotonic deactivation in the subsequent cycles, as a result of the progressive sintering of the copper species.

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

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

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

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

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

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

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

Vol. 81, pp. 674-685 
article DOI URL 
Abstract: In this manuscript, we report on the phase behavior of a novel family of ionic liquid crystals based on wedge-shaped amphiphilic mesogens of benzene sulfonates with different counterions (Li, Na, K and Cs) and polymerizable acrylic groups in the alkyl chain periphery. The phase diagrams of these compounds were explored with differential scanning calorimetry, polarized optical microscopy and temperature-dependent small-angle X-ray scattering. Lamellar and columnar liquid-crystalline phases were identified. Ionic conductivity was measured by impedance spectroscopy at different relative humidities. The influence of the counterion on the mesostructure and electrical conductivity is further discussed. Finally, it is demonstrated how photopolymerization can be employed to arrest the different supramolecular structures and transform the low-molecular-weight nanostructured liquid into self-standing ion conducting polymer membranes. © 2016 Elsevier Ltd

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

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

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

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

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

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

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

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

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

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

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

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

Kiener, J., Ersen, O. and Parmentier, J. Mesoporous C/CrN and C/VN Nanocomposites Obtained by One-Pot Soft-Templating Process 2016 Inorganics
Vol. 4(3), pp. 22 
article DOI  
Abstract: Nanocomposites of ordered mesoporous carbon associated with chromium nitride (CrN) or vanadium nitride (VN) nanoparticles were obtained by a simple one-pot synthesis based on the solvent evaporation induced self-assembly (EISA) process using Pluronic triblock surfactant as soft-template and a phenol-based resin (resol) as carbon precursor. These nanocomposites were characterized by X-ray diffraction, nitrogen physisorption and Transmission Electron Microscopy (TEM) techniques. Electron tomography (or 3D-TEM) technique was particularly useful for providing direct insight on the internal architecture of C/CrN nanocomposite. Nanocomposites showed a very well organized hexagonal mesoporous carbon structure and a relatively high concentration of nanoparticles well distributed in the porous network. The chromium and vanadium nitrides/mesoporous carbon nanocomposites could have many potential applications in catalysis, Li-ion batteries, and supercapacitors.

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

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

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

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

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

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

These two phosphorescent materials only constitute the third and fourth examples of triple heteroleptic cationic iridium complexes to be tested in electroluminescent devices. LECs fabricated with this almost unknown class of iridium complex furnished green-emitting devices. Parallel to investigations devoted to electroluminescent properties, photophysical and electrochemical properties of the two new complexes were examined. Density functional theory calculations were also performed to provide insight into the electronic structure of the two emitters. © 2016 Elsevier B.V. All rights reserved.

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

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

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

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

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

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

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

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

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

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

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

Vol. 75, pp. 30301

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

Abstract: This work is devoted to the development and application of a new experimental method that combines in situ ultrafast calorimetry on a chip with nanofocus synchrotron X-ray diffraction.

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

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

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

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

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

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

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

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

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

Nita, C., Bensafia, M., Vaulot, C., Delmotte, L. and Matei Ghimbeu, C. Insights on the synthesis mechanism of green phenolic resin derived porous carbons via a salt-soft templating approach 2016 Carbon
Vol. 109, pp. 227-238 
article URL 
Abstract: Abstract A combined salt-soft template approach to synthesize porous carbon materials is reported along with their synthesis mechanism. This consists in the evaporation induced self-assembly (EISA) of aqueous solutions containing green phenolic resins, a triblock copolymer template and a metallic salt, followed by thermal treatment and washing. The increase of pH up to 5 using NaOH, induces significant improvement in the carbon microporosity but in the detrimental of mesoporosity. As suggest by 13C and 1H NMR, the mesoporosity lost is caused by the decrease of H-bonding and self-assembly between the phenolic resin and the template due to the strong “salting-out” effect of OH ions. For higher pH (pH-9), the porosity start to decrease and graphene-sheet like morphology is formed. The microporosity varies with the salt in the following order: KCl &gt; NaCl &gt; LiCl, while the mesoporosity in the opposite way. The structure changes as well from smooth turbostatic (KCl) to defective graphitic one (NaCl, LiCl). These textural and structural modifications are explained in terms of cation hydration enthalpy and cation-π binding energy and by the competition between the metal salt cations and the Na ions (used to regulate the pH) for water or phenolic resin aromatic ring sites.

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

Oumellal, Y., Provost, K., Ghimbeu, C., De Yuso, A. and Zlotea, C. Composition and size dependence of hydrogen interaction with carbon supported bulk-immiscible Pd-Rh nanoalloys 2016 Nanotechnology
Vol. 27(46), pp. - 
article DOI URL 
Abstract: In-depth clarification of hydrogen interaction with noble metal nanoparticles and nanoalloys is essential for further development and design of efficient catalysts and hydrogen storage nanomaterials. This issue becomes even more challenging for nanoalloys of bulk-immiscible metals. The hydrogen interaction with bulk-immiscible Pd-Rh nanoalloys (3-6 nm) supported on mesoporous carbon is studied by both laboratory and large scale facility techniques. X-ray diffraction (XRD) reveals a single phase fcc structure for all nanoparticles confirming the formation of nanoalloys in the whole composition range. In situ extended x-ray absorption fine structure (EXAFS) experiments suggest segregated local structures into Pd-rich surface and Rh-rich core coexisting within the nanoparticles. Hydrogen sorption can be tuned by chemical composition: Pd-rich nanoparticles form a hydride phase, whereas Rh-rich phases do not absorb hydrogen under ambient temperature and pressure conditions. The thermodynamics of hydride formation can be tailored by the composition without affecting hydrogen capacity at full hydrogenation. Furthermore, for hydrogen absorbing nanoalloys, in situ EXAFS reveals a preferential occupation of hydrogen for the interstitial sites around Pd atoms. To our knowledge, this is the first study providing insights into the hydrogen interaction mechanism with Pd-Rh nanoalloys that can guide the design of catalysts for hydrogenation reactions and the development of nanomaterials for hydrogen storage. © 2016 IOP Publishing Ltd.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Vol. 3(19), pp. -

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

Vol. 7(47), pp. 7316-7324 
article URL 
Abstract: Four dihydroxyanthraquinone derivatives [i.e. 1,2-dihydroxyanthraquinone (12-DHAQ), 1,4-dihydroxyanthraquinone (14-DHAQ), 1,5-dihydroxyanthraquinone (15-DHAQ), and 1,8-dihydroxyanthraquinone (18-DHAQ)], when combined with various additives (e.g. iodonium salt, tertiary amine, N-vinylcarbazole, phenacyl bromide, and 4-cyanopentanoic acid dithiobenzoate), are investigated as photoinitiating systems for free radical photopolymerization [e.g. cross-linked free radical photopolymerization of multifunctional monomers or reversible addition-fragmentation chain transfer (RAFT) photopolymerization of monofunctional monomers] and cationic photopolymerization. 14-DHAQ, 15-DHAQ and 18-DHAQ exhibit good solubility in solvent (acetonitrile) and monomers (methacrylate and epoxide) and demonstrate absorption maxima in the blue light wavelength range, which makes them potential candidates to work under the irradiation of a household blue LED bulb. Among all the investigated dihydroxyanthraquinone derivative-based photoinitiating systems, 18-DHAQ based systems exhibit the highest photoinitiating ability for both free radical and cationic photopolymerization while 12-DHAQ based systems are inefficient. It illustrates that the positions of hydroxyl substituents in the anthraquinone molecule play a significant role in the photoinitiating ability of dihydroxyanthraquinone derivatives. The photochemical mechanisms are investigated by fluorescence, laser flash photolysis, steady state photolysis, and electron spin resonance spin trapping techniques, and the results are in agreement with the relevant photopolymerization efficiency.

Abstract: The cations and radicals produced in aminothiazonaphthalic anhydride derivatives (ATNAs) combined with an iodonium salt, N-vinylcarbazole, amine, or chloro triazine initiate the ring-opening cationic polymerization of epoxides and the free radical polymerization of acrylates under LEDs at 405 or 455 nm. The photoinitiating ability of these novel photoinitiating systems is higher than that of the well-known camphorquinone-based systems. An example of the high reactivity of the new proposed photoinitiator is also provided in resins for 3D-printing using a LED projector@405 nm. The chemical mechanisms are investigated by steady-state photolysis, cyclic voltammetry, fluorescence, laser flash photolysis, and electron spin resonance spin-trapping techniques. © 2015 Wiley Periodicals, Inc.

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

Vol. 8(13), pp. 2227-2233 
article DOI URL 
Abstract: The novel role of metal-based complexes as photoinitiator catalysts fits well into the concept of green chemistry, as it realizes the activation of polymer synthesis processes by visible light that are abundant in the solar light and allows the marked reduction of photoinitiator amount in the systems. In the present paper, a series of iron complexes (FeC_x) with various ligands have been proposed as new photoinitiator catalysts to initiate the cationic polymerization of epoxides or the free radical polymerization of acrylates upon a near-UV or visible-light LED exposure. The ligands play an important role on the light absorption properties and the photoinitiation ability of the iron complexes. In combination with one or two additives, FeC_x are capable to efficiently generate radicals, cations, and radical cations through an oxidative or a reductive path. Two of the newly developed FeC_x-based photoinitiating systems exhibited comparable photoinitiation efficiency with the commercial Type I photoinitiator bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide (BAPO). Owing to the photocatalytic effect, remarkable photoinitiation efficiencies have been achieved by using very low concentration of iron complexes (0.02 wt %) in the systems. The involved photochemical mechanisms have been studied using electron spin resonance spin trapping, steady state photolysis, cyclic voltammetry, and laser flash photolysis techniques. © 2016 WILEY-VCH Verlag GmbH & Co.

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

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

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

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

Novel naphthalimide-amine based photoinitiators operating under violet and blue LEDs and usable for various polymerization reactions and synthesis of hydrogels 2016 Polym. Chem.

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

Abstract: A short review of the role of photocatalysts in photopolymerization reactions is presented. A special emphasis is placed on photoredox catalysts leading to i) high-performance initiating systems for polymerization upon low light intensity for the use of light emitting diodes (LEDs) and/or visible light and ii) controlled radical photopolymerization (CRP2) processes with formation/reactivation of dormant species triggered by light.

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

Vol. 37(10), pp. 840-844

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