Towards metal free supported quaternary ammonium halides catalysts for an optimized cycloaddition of CO 2 onto styrene oxide

Miguel Alonso de La Peña, Matthieu Balas, Julie Kong, Richard Villanneau, Lorraine Christ, A. Tuel, Franck Launay

The present work reports on a large selection of porous siliceous materials functionalised by quaternary ammonium salts (QAS) with various pores structures, possible doping with Zn2+, and different ammonium salt substituents as well as halide counter-ions. After characterization by TGA, N2…

New Insights into the Structure and Degradation of Alizarin Lake Pigments: Input of the Surface Study Approach

Guanzheng Zhuang, Silvia Pedetti, Yoan Bourlier, Philippe Jonnard, Christophe Méthivier, Philippe Walter, Claire-Marie Pradier, Maguy Jaber

Alizarin (Az) lake is a typical example of madder lake pigments that are widely used in cultural heritages. Previous work focused on the complex formation in solution, theoretical models, and crystallized stoichiometric structures (Az/Al3+ = 1:1 or 2:1). However, the classical recipe for preparing…

CO2 valorization using epoxides under mild conditions

Chetna Mohabeer, Lionel Estel, Laurent Bischoff, Vincent Levacher, Marie-Pierre Denieul, Alain Ledoux, Salim Derrouiche

Carbon dioxide is the major greenhouse gas suspected to produce the climatic change. In order to reduce the emissions of CO 2 , several ways have been studied like capture process, geological storage and valorization. Recently one of the most important studies is concentrated on chemical…

Design of plasmonic nanoparticles and their use for biotoxin immunosensing, Conception de nanoparticules plasmoniques et leur utilisation pour l'immunodétection d’une biotoxine

Lu Zhang

Staphylococcal enterotoxin A (SEA) produced by some Staphylococcus aureus strains is a major cause of food poising and especially represents the second cause of foodborne diseases in France. Plasmonic nanoparticles with unique optical properties are widely applied as transducers in biosensing…, L'entérotoxine A du staphylocoque (SEA) produite par certaines souches de Staphylococcus aureus est une cause majeure d'intoxication alimentaire et représente la deuxième cause de maladies d'origine alimentaire en France. Les nanoparticules (NPs) plasmoniques aux propriétés optiques…

Nanoparticles of Ni strongly embedded in porous silica : towards the design of efficient catalysts for lignin hydrogenolysis, Nanoparticules de Ni incorporées dans de la silice poreuse : vers la conception de catalyseurs efficaces pour l'hydrogénolyse de la lignine

Rita Raachini

Phenols may be obtained from lignin instead of petroleum. Here, improving lignin conversion by hydrogenolysis, while limiting side hydrogenation of produced phenols using nickel-based catalysts instead of noble metals, was our main concern. Porous materials made of highly dispersed nickel onto…, Les phénols peuvent être obtenus à partir de la lignine plutôt que du pétrole. Notre principale préoccupation était d’améliorer la conversion de la lignine par hydrogénolyse, tout en limitant l’hydrogénation des phénols produits en utilisant des catalyseurs à base de Ni au lieu de métaux nobles.…

Deciphering the improvement in (H2-)C3H6-SCR performance of Ag/Al2O3 catalysts prepared from warm-water-treated alumina: A NMR-assisted identification of the Ag anchoring sites of the alumina support

Yannick Millot, Guylène Costentin, Clémence Rodigue, Thomas Onfroy, Cyril Thomas

Lean exhausts aftertreatment has been the subject of numerous investigations due to ever stringent regulations on pollutants emissions such as that of NOx. Among aftertreatment technologies, the selective catalytic reduction of NOx by the hydrocarbons (HC-SCR) has been studied intensively, in…

A High-Pressure, High-Temperature Flow Reactor Simulating the Hadean Earth Environment, with Application to the Pressure Dependence of the Cleavage of Avocado Viroid Hammerhead Ribozyme

Kunio Kawamura, Mari Ogawa, Noriko Konagaya, Yoshimi Maruoka, Jean-François Lambert, Louis M. P. Ter-Ovanessian, Jacques Vergne, Guy Hervé, Marie-Christine Maurel

The RNA world hypothesis suggests that chemical networks consisting of functional RNA molecules could have constructed a primitive life-like system leading a first living system. The chemical evolution scenario of RNA molecules should be consistent with the Hadean Earth environment. We have…

Oxidation of laccase for improved cathode biofuel cells performances

Meihui Zheng, Sophie Griveau, Christine Dupont-Gillain, Michel J Genet, Claude Jolivalt

Graphite rods were modified by substituted aryldiazonium salts allowing subsequent laccase immobilisation and direct electron transfer at the cathode. Two covalent enzyme immobilisation methods were performed with carboxy and amino substituted grafted groups, either via the formation of an amide…
