Crops Prod.}, year = {2015}, volume = {70}, pages = {332-340}, abstract = {Six porous carbon materials, produced by hydrothermal treatment of flavonoid tannin and subsequent carbonization at 1173 K, were tested as electrodes of supercapacitors. Four of these carbons were doped with nitrogen by putting tannin in contact with ammonia before or during the hydrothermal treatment. The pyrolyzed hydrothermal carbons had moderate surface areas, within the range 442-684 m2 g-1, and nitrogen contents ranging from 0.7 to 8.0 wt.\%. Specific capacitances as high as 320 F g-1 and normalized capacitances as high as 58 ?F cm-2 were measured at 2 mV s-1. These performances are comparable with those obtained with high surface area-activated carbons, whereas, normalized capacitances values are among the highest ever reported. Mesostructuration, within the range 3-13 nm, of these materials appears to be a good strategy to improve their electrochem. performances at higher scan rates. We confirmed the beneficial role of oxygen up to 18 wt.\%, while an optimum in nitrogen content exists from 3 to 6 wt.\%.

Such gels were subcritically dried, freeze-dried or supercritically dried to obtain organic xerogels, cryogels and aerogels, respectively, having nitrogen contents between 3.0 and 3.7 wt.\%. After pyrolysis at 900 \(^{\circ}\)C, the materials presented nitrogen contents ranging from 1.9 to 3.0 wt.\%, and surface areas as high as 860, 754 and 585 m2 g?1 for carbon aerogels, cryogels and xerogels, respectively. All of them displayed micropores associated with different mesopore volumes, depending on both the drying method and initial dilution of the precursor. When tested as supercapacitor electrodes, these carbon gels presented outstanding specific and normalised capacitances, up to 387.6 F g?1 and 69.5 ?F cm?2, respectively, at a scan rate of 2 mV s?1 in 4 mol L?1 H2SO4 aqueous solution. These performances are higher than those obtained with high apparent surface area-activated carbons, as the measured capacitances are indeed among the highest ever reported. The influence of nitrogen- and oxygen-based moieties was investigated, and optimal N and O contents of 2–3 and 17–18 wt.\%, respectively, were observed.}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Braghiroli, F.

High-resoln. transmission electron microscopy (HRTEM) shows that the av. grain size of NWs increases with increasing Te content. Our results also reveal that the electrodeposited bismuth telluride NWs are n-type, and their elec. cond. increases with increasing Te content.

In agreement with density functional theory calculations, the collected data show an overall gradual variation in the transport properties from metallic to semiconducting behavior on going from x = 3.4 to 3.8. The results evidence subtle variations in the electronic properties with the Ag content, typified by both positive and negative phonon-drag effects together with thermopower and Hall coefficient of opposite signs. Analysis of the data suggests that these features may be due to peculiarities of the dispersion of the valence bands in the vicinity of the chemical potential. A drastic influence of the Ag content on the thermal transport was evidenced by a pronounced change in the temperature dependence of the specific heat below 10 K. Nonlinearities in the Cp(T3) data are correlated to the concentration of Ag atoms, with an increase in x resulting in a more pronounced departure from a Debye law. The observed behavior mirrors that of ionic conductors, suggesting that AgxMo9Se11 for x ? 3.6 might belong to this class of compounds.}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {ZHOU, T. and COLIN, M. and CANDOLFI, C. and Boulanger, C. and DAUSCHER, A. and Santava, E. and HEJTMANEK, J. and BARANEK, P. and AL RAHAL AL ORABI, R. and POTEL, M. and Fontaine, B. and GOUGEON, P. and Gautier, R. and LENOIR, B.} } @Article { CP2S017, title = {Microstructure modifications and associated hardness and corrosion improvements in the AISI 420 martensitic stainless steel treated by High Current Pulsed Electron Beam (HCPEB)}, journal = {Surface and Coatings Technology}, year = {2014}, abstract = {Abstract The surface of the AISI 420 martensitic stainless steel was subjected to High Current Pulsed Electron Beam (HCPEB) treatment. The microstructure in the melted layer consisted of a three phase mixture: (i) fine ?-Fe grains formed via epitaxial growth from the substrate, (ii) larger ?–grains nucleated from the top surface of the melt and (iii) some needles-like variants issued from the solid state martenitic transformation. Despite this complex multi-phase microstructure, the corrosion performance, tested in a sulfuric acid solution, was significantly enhanced by the HCPEB treatment. The increase in corrosion potential and delayed pitting are essentially attributed to an increase in Cr content, rising from 13.3 wt. \% in the bulk to about 14 wt. \% at the surface, together with a very limited amount of surface craters. This low density of craters did not give rise to significant deep hardening in the sub-surface but the top surface melted layer hardness was increased by more than 50\% because of the triggering of the martensitic transformation.}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, keywords = {High Current Pulsed Electron Beam Treatment (HCPEB) Surface hardening Corrosion Phase selection Phase transformation Martensitic steel}, author = {Samih, Y. and Marcos, G. and Stein, N. and Allain, N. and Fleury, E. and Dong, C. and Grosdidier, T.} } @Article { 208-1878, title = {Electrodeposition of bismuth telluride nanowires with controlled composition in polycarbonate membranes}, journal = {Electrochimica Acta}, year = {2012}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Frantz, Cedric and Stein, Nicolas and Zhang, Yudong and Bouzy, Emmanuel and Picht, Oliver and Toimil-Molares, Maria Eugenia and Boulanger, Clotilde} } @Article { 208-1605, title = {Pore structure and electrochemical performances of tannin-based carbon cryogels}, journal = {Biomass \& Bioenergy}, year = {2012}, volume = {39}, pages = {274-282}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Amaral-Labat, G. and Szczurek, A. and Fierro, V. and Stein, N. and Boulanger, C. and Pizzi, A. and Celzard, A.} } @Article { 208-1882, title = {Cyclic-voltammetry study of bismuth telluride electrodeposition in polycarbonate etched ion -track membranes}, journal = {GSI Scientific Report}, year = {2011}, volume = {PNI-MR-33}, pages = {401}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Stein, N and Boulanger, C and Frantz, C and Picht, O and Toimil-Molares, M} } @Article { 208-1472, title = {Electrodeposition and Characterization of Bismuth Telluride Nanowires}, journal = {Journal of Electronic Materials}, year = {2010}, volume = {39}, number = {9}, pages = {2043-2048}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Frantz, C. and Stein, N. and Gravier, L. and Granville, S. and Boulanger, C.} } @Article { 208-1457, title = {Antioxidant enzyme activities as affected by trivalent and hexavalent chromium species in Fontinalis antipyretica Hedw}, journal = {Chemosphere}, year = {2008}, volume = {73}, number = {3}, pages = {281-290}, note = {D{\'e}partement CP2S : Chimie et {\'e}lectrochimie des mat{\'e}riaux}, author = {Dazy, M. and Beraud, E. and Cotelle, S. and Meux, E. and Masfaraud, J.
