Estelle Palierse, Christophe Hélary, Jean-Marc Krafft, Isabelle Génois, Sylvie Masse, Guillaume Laurent, Maria I Alvarez Echazu, Mohamed Selmane, Sandra Casale, Laetitia Valentin, Antoine Miche, Ben C.L. Chan, Clara B.S. Lau, Margaret Ip, Martin F Desimone, Thibaud Coradin, Claude Jolivalt

Aseptic loosening and bacterial infections are the two main causes of failure for metallic implants used for joint replacement. A coating that is both bioactive and possesses antimicrobial properties may address such shortcomings and improve the performance of the implant. We have sought to study…

Conception de systèmes catalytiques hétérogènes chimioenzymatiques pour l'époxydation, Conception of heterogeneous chemioenzymatic catalysts for epoxydation

Noémie Balistreri

L'objectif de ce travail est de développer un système catalytique hétérogène pour l'époxydation en utilisant directement O2 de l'air plutôt que H2O2 commercial. La stratégie adoptée a été de coupler la production in situ de H2O2, catalysée par la glucose oxydase (GOx), avec un…, The objective of this work was to develop an heterogeneous catalyst system supplied by dioxygen, rather than commercial H2O2, in order to carry out epoxidation reactions. Our strategy was to couple the in situ production of H2O2, catalyzed by glucose oxidase (GOx), with a Ti-based catalyst. The…

On the origin of the changes in color of Ag/Al2O3 catalysts during storage

Tesnim Chaieb, Dalil Brouri, Sandra Casale, Jean-Marc Krafft, Tiago da Silva, Cyril Thomas, Laurent Delannoy, Catherine Louis

Despite the large number of catalytic studies involving Ag/Al2O3 catalysts, especially in deNOx reactions, the phenomenon of ageing observed during catalysts storage after preparation by impregnation followed by a calcination treatment, has not been reported earlier and rises questions. The present…

Adsorption of l-DOPA Intercalated in Hydrated Na-Saponite Clay: A Combined Experimental and Theoretical Study

K. El Adraa, V. Timon, J.-F. Lambert, Abdel-Rahman Al-Rabaa, F. Jaber, M. Jaber, Frederik Tielens

The intercalation of L-DOPA into the interlayer space of saponite, a 2:1 phyllosilicate, and the nature of host−guest interactions are investigated by a combined experimental and theoretical approach. L-DOPA zwitterions are accommodated vertically in the interlayer region as a bilayer of partially…

Bimetallic Fe-Ni/SiO2 catalysts for furfural hydrogenation: Identification of the interplay between Fe and Ni during deposition-precipitation and thermal treatments

Dichao Shi, Qifeng Yang, Christi Peterson, Anne-Félicie Lamic-Humblot, Jean-Sébastien Girardon, Anne Griboval-Constant, Lorenzo Stievano, Moulay Tahar Sougrati, Valérie Briois, Paul A.J. Bagot, Robert Wojcieszak, Sébastien Paul, Eric Marceau

Supported Fe-Ni catalysts have been reported for their activity and selectivity in the hydrogenation of unsaturated organic molecules. However, the control of the size and composition of the bimetallic nanoparticles remains a bottleneck when oxide-supported catalysts are prepared by impregnation,…

Activity of molybdenum and tungsten oxycarbides in hydrodenitrogenation of carbazole leading to isomerization secondary reaction of bicyclohexyl. Results using bicyclohexyl as feedstock

Marek Lewandowski, Agnieszka Szymańska-Kolasa, Céline Sayag, Gérald Djéga-Mariadassou

The catalytic activities of bulk tungsten and molybdenum oxycarbides, (W2C and Mo2C) have been specifically studied in the isomerization occurring during the hydrodenitrogenation (HDN) of carbazole. The two catalysts have been characterized by several physico-chemical techniques such as X-Ray…

Heterogeneous Partial (amm) Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

Jacques C. Védrine

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main…

Synthèse prébiotique de Ribonucléotides sur des surfaces minérales, Prebiotic synthesis of Ribonucleotides on mineral surfaces

Mariame Akouche

Dans le contexte prébiotique du " monde ARN ", les ribonucléotides sont considérés comme étant les premières espèces à avoir émergé sur Terre. En milieu aqueux, leur formation est défavorable thermodynamiquement. Les voies de synthèse de nucléotides décrites en phase homogène impliquent l…, In the « RNA world» prebiotic scenario, ribonucleotide polymers are considered as the first biochemical species to have emerged. However, in aqueous solution, their formation through conventional mechanisms of condensation is thermodynamically forbidden. Several synthesis pathways of nucleotides…
