Electrospun Poly(ε-caprolactone) Fiber Scaffolds Functionalized by the Covalent Grafting of a Bioactive Polymer: Surface Characterization and Influence on in Vitro Biological Response

Gana Amokrane, Vincent Humblot, Emile Jubeli, Najet Yagoubi, Salah Ramtani, Véronique Migonney, Céline Falentin-Daudré

The purpose of this study is to present the poly(caprolactone) (PCL) functionalization by the covalent grafting of poly(sodium styrene sulfonate) on electrospun scaffolds using the "grafting from" technique and evaluate the effect of the coating and surface wettability on the biological…

Experimental clues for detecting biosignatures on Mars

J.-C. Viennet, S. Bernard, Corentin Le Guillou, P. Jacquemot, E. Balan, L. Delbes, B. Rigaud, T. Georgelin, M. Jaber

Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, thereby preserving potential remains of martian life. Yet, volcanism and impactors have periodically triggered…

On the kinetics of CO oxidation by O2 over RhI(CO)2 catalytic species anchored to a zeolitic support

Céline Fontaine-Gautrelet, Cyril Thomas, Jean-Marc Krafft, Gérald Djéga-Mariadassou

The reactivity of RhI(CO)2 towards CO oxidation was studied on a model Rh(0.7 wt%)/HY material. The kinetic results show that RhI(CO)2 exhibit a fairly low activity. It is therefore suggested that the catalytic species responsible for the enhanced activity of Rh/Ce0.68Zr0.32O2 [Manuel et al., J.…

Sulfamide chemistry applied to the functionalization of self-assembled monolayers on gold surfaces

Loïc Pantaine, Vincent Humblot, Vincent Coeffard, Anne Vallee

Aniline-terminated self-assembled monolayers (SAMs) on gold surfaces have successfully reacted with ArSO₂NHOSO₂Ar (Ar = 4-MeC₆H₄ or 4-FC₆H₄) resulting in…

ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…

Design de composites verts pour la dépollution des terres agricoles : expérience et théorie, Design of green composite for the decontamination of agricultural land : experimental and theoretical

Khaled El Adraa

Des matériaux verts biodégradables à base de Montmorillonite et de cystéine ont été préparés dans le but de co-adsorber des cations de métaux lourds et des polluants émergeants en combinant l’expérience et la théorie (calculs DFT). Les analyses thermiques différentielles ont permis d’estimer le…, Layered silicates like smectites are important soil components. Many works have been devoted to functionalize these materials in order to increase their chelating properties which may help retain heavy metals. It is well known that Cd2+, Hg2+, Pb2+, Co2+ and Zn2+ forms stable complexes with sulfur-…

New ammonium surfactant-stabilized rhodium(0) colloidal suspensions: influence of novel counter-anions on physico-chemical and catalytic properties.

Novel anionic species, such as hydrogen carbonate (HCO(3)(−)), fluoride (F(−)), triflate (CF(3)SO(3)(−)), tetrafluoroborate (BF(4)(−)) and chloride (Cl(−)) were investigated as new partners of water soluble N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium salts, used as a protective agent of…

Electron Transfer at the Metal Oxide/Electrolyte Interface: A Simple Methodology for Quantitative Kinetics Evaluation

Iban Azcarate, Cyrille Costentin, Christophe Méthivier, Christel Laberty-Robert, Alexis Grimaud

While quantitative models exist for measuring rate constants for electron exchange at the surface of semiconductors to or from redox couples in solution, their use is very limited for studying transition metal oxide electrodes. Taking advantage of the possibility of tuning the doping level of WO 3…
