Carbon Dioxide Reforming of Methane over Nickel-Supported Zeolites: A Screening Study

Carmen Bacariza, Leila Karam, Nissrine El Hassan, José Lopes, Carlos Henriques

As the utilization of zeolites has become more frequent in the dry reforming of methane (DRM) reaction, more systematic studies are required to evaluate properly the influence of zeolites’ composition and framework type on the performance. Therefore, in this work, a step-by-step study was performed…

Effect of Nontronite Smectite Clay on the Chemical Evolution of Several Organic Molecules under Simulated Martian Surface Ultraviolet Radiation Conditions

Olivier Poch, Maguy Jaber, Fabien Stalport, Sophie Nowak, Thomas Georgelin, Jean-François Lambert, Cyril Szopa, Patrice Coll

Most of the phyllosilicates detected at the surface of Mars today are probably remnants of ancient environments that sustained long-term bodies of liquid water at the surface or subsurface and were possibly favorable for the emergence of life. Consequently, phyllosilicates have become the main…

Impact of nontronite on the evolution of organic molecules at the surface of Mars

Patrice Coll, Olivier Poch, Maguy Jaber, Jean-François Lambert, Thomas Georgelin, Cyril Szopa, Fabien Stalport

Several evidences suggest that early Mars offered favorable conditions for long-term sustaining water. As a consequence, we can assume that in those days, endogenous chemical processes, or even primitive life, may have produced organic matter on Mars. Moreover, exogenous delivery from small bodies…

Aerosol-assisted self-assembly of hybrid Layered Double Hydroxide particles into spherical architectures

Vanessa Prevot, Claire Szczepaniak, Maguy Jaber

Acetate intercalated NiAl-Layered Double Hydroxide nanoparticles were prepd. by polyol process and further used as building blocks to form hybrid LDH spheres by a spray drying technique. The spherical aggregated LDH particles display a polydispersed size with a diam. ranging from 47 nm to 2 μm.…

Electrosynthesis of pyrrole 3-carboxylic acid copolymer films and nanotubes with tunable degree of functionalization for biomedical applications

Cecile J. Roy, Lucas Leprince, Arnaud de Boulard, Jessem Landoulsi, Vincent Callegari, Alain M. Jonas, Sophie Demoustier-Champagne

Tailoring polypyrrole (PPy), an electroactive polymer, with functional groups to which a variety of bioactive molecules can be tethered is highly attractive for building biological structures on conducting surfaces for a range of biomedical applications. In this respect, we investigate the effects…

Advances in the preparation of supported gold catalysts: Mechanism of deposition, simplification of the procedures and relevance of the elimination of chlorine

Antoine Hugon, Nadia El Kolli, Catherine Louis

The paper focuses on the chem. mechanisms involved during the prepn. of gold catalysts supported on alumina and titania and on attempts to simplify the procedures of prepn. Three methods involving the same gold loading (1 wt%) and the same precursor, HAuCl4, were studied: impregnation in excess of…

A versatile approach for the immobilization of amines via copper-free "click" reaction between azido self-assembled monolayer and alkynyl Fischer carbene complex. Application to the detection of staphylococcal enterotoxin A antibody

Pratima Srivastava, Amithaba Sarkar, Sudeshna Sawoo, Amarnath Chakraborty, Piyali Dutta, Othman Bouloussa, Christophe Methivier, Claire-Marie Pradier, Souhir Boujday, Michele Salmain

A copper-free "click" reaction between an azido-terminated self-assembled monolayer (SAM) chemisorbed on planar gold-coated glass sensors and an alkynyl Fischer carbene complex yielded functionalized surfaces onto which facile and swift grafting of amine-containing molecules was achieved…
