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…

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.…

Microcalorimetric and thermodynamic studies of CO2 and methanol adsorption on magnesium oxide

C. Pighini, Thomas Belin, Jerome Mijoin, Patrick Magnoux, Guylene Costentin, Helene Lauron-Pernot

Both Lewis and Bronsted basic properties of magnesium oxide (MgO) are, respectively, studied by adsorption of CO2 and methanol CH3OH. Various chemical synthesis of pure magnesium oxide (commercial, sol-gel and precipitation methods) are used. The influence of small amounts of alkaline (Na+ and Li+)…

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.…

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…
