In situ detection and characterization of potable water biofilms on materials by microscopic, spectroscopic and electrochemistry methods

Jean Gamby, Alain Pailleret, Carol Boucher Clodic, Claire-Marie Pradier, Bernard Tribollet

We studied biofilm formation on stainless steel occurring in a drinking water distribution system which operated in parallel at 20 and 37 °C, in order to focus on the effect of temperature rather than on other operational and water quality parameters. A surface conditioning step was followed as a…

A comparative study of the catalysis of peptide bonds formation by oxide surfaces

Jean-Francois Lambert, Maguy Jaber, Thomas Georgelin, Lorenzo Stievano

It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which…

Chemical evolution of organic molecules under Mars-like UV radiation conditions simulated in the laboratory with the MOMIE setup

O. Poch, Patrice Coll, Cyril Szopa, F. Stalport, T. Georgelin, M. Jaber, J.F. Lambert

The search for organic carbon at the surface of Mars, as clues of past habitability or remnants of life, is a major science goal of Mars' exploration. Understanding the chemical evolution of organic molecules under current Martian environmental conditions is essential to support the past,…

Temporin-SHa peptides grafted on gold surfaces display antibacterial activity

Andres Lombana, Zahid Raja, Sandra Casale, Claire-Marie Pradier, Thierry Foulon, Ali Ladram, Vincent Humblot

Development of resistant bacteria onto biomaterials is a major problem leading to nosocomial infections. Antimicrobial peptides are good candidates for the generation of antimicrobial surfaces because of their broad-spectrum activity and their original mechanism of action (i.e. rapid lysis of the…

Heterogeneous catalyst preparation in ionic liquids: Titania supported gold nanoparticles

Camella Oumahi, Jean Lombard, Sandra Casale, Christophe Calers, Laurent Delannoy, Catherine Louis, Xavier Carrier

This work reports the use of ionic liquids (ILs) as solvent for the synthesis of Au/TiO2 heterogeneous catalysts. It is shown that the versatility of the physico-chemical properties of ILs makes them interesting solvents for a broad control of supported metal nanoparticles (NPs) size and for a fine…

On an additional promoting role of hydrogen in the H2-assistedC3H6-SCR of NOxon Ag/Al2O3: A lowering of the temperature offormation-decomposition of the organo-NOxintermediates?

Cyril Thomas

tThe addition of minute amounts of H2to the selective catalytic reduction of nitrogen oxides (NOx)by hydrocarbons (HC-SCR) has been shown to promote the reduction of NOxat remarkably lowerreaction temperatures on Ag/Al2O3catalysts. Despite extensive investigations, the origin of this remark-able…

ZSM-5/SBA-15 microporous/mesoporous composites prepared by a microwave-assisted zeolitisation of Al-SBA-15 mesoporous solids

Sami Habib, Franck Launay, Henri El Zakhem, Matjaž Mazaj, Flavien Guenneau, Patricia Beaunier, Dalil Brouri, Nataša Novak Tušar, Venčeslav Kaučič, Antoine Gedeon

ZSM-5/SBA-15 composites with high textural properties were synthesised by a microwave-assisted zeolitisation of Al-SBA-15 in the presence of tetrapropylammonium bromide. The effect of the hydrothermal treatment temperature and of ammonium fluoride, often used as a catalyst, was studied. Resulting…

UV irradiation study of a tripeptide isolated in an argon matrix: A tautomerism process evidenced by infrared and X-ray photoemission spectroscopies.

Eva Mateo-Marti, Claire-Marie Pradier

Matrix isolation is a powerful tool for studying photochemical processes occurring in isolated molecules. In this way, we characterized the chemical modifications occurring within a tri peptide molecule, IGF, when exposed to the influence of Ultraviolet (UV) irradiation. This paper first describes…
