The antibacterial activity of Magainin I immobilized onto mixed thiols Self-Assembled Monolayers

Vincent Humblot, Jean-Fabrice Yala, Pascal Thebault, Kada Boukerma, Arnaud Héquet, Jean-Marc Berjeaud, Claire-Marie Pradier

An antibacterial peptide, Magainin I, was covalently bound to a mixed 11-mercaptoundecanoïc acid (MUA) and 6-mercaptohexanol (C6OH) (ratio 1:3) Self-Assembled Monolayer (SAM) on gold surfaces. Each step of the surface functionalization was characterized by Polarization Modulation Reflection…

Cobalt Based Catalysts Supported on Two Kinds of Beta Zeolite for Application in Fischer-Tropsch Synthesis

Renata Sadek, Karolina Chalupka, Pawel Mierczynski, Jacek Rynkowski, Jacek Gurgul, Stanislaw Dzwigaj

Co-containing Beta zeolite catalysts prepared by a wet impregnation and two-step postsynthesis method were investigated. The activity of the catalysts was examined in Fischer-Tropsch synthesis (FTS), performed at 30 atm and 260 °C. The physicochemical properties of all systems were investigated by…

Bimetallic Au-Ag/TiO2 catalyst prepared by deposition-precipitation: High activity and stability in CO oxidation

A. Sandoval, A. Aguilar, C. Louis, Agnes Traverse, Rodolfo Zanella

Au-Ag bimetallic catalysts supported on TiO2 were prepared by sequential deposition-precipitation method, silver first and then gold. Au-Ag catalysts with different Au/Ag atomic ratios were synthesized. XANES and H2 TPR results show that gold is more easily reduced in bimetallic catalysts than in…

Emergence of Order in Origin-of-Life Scenarios on Mineral Surfaces: Polyglycine Chains on Silica

Ola El Samrout, Marco Fabbiani, Gloria Berlier, Jean-François Lambert, Gianmario Martra

The polymerization of amino acids (AAs) to peptides on oxide surfaces has attracted interest owing to its high importance in biotechnology, prebiotic chemistry, and origin of life theories. However, its mechanism is still poorly understood. We tried to elucidate the reactivity of glycine (Gly) from…

Palladium Nanowires Synthesized in Hexagonal Mesophases: Application in Ethanol Electrooxidation

Faygal Ksar, Geetarani Surendran, Laurence Ramos, Bineta Keita, Louis Nadjo, Eric Prouzet, Patricia Beaunier, Agnes Hagege, Fabrice Audonnet, Hynd Remita

Palladium nanowires (of length a few tens of nanometers) are synthesized in a hexagonal mesophase formed by a quaternary system (Pd-doped water, surfactant, cosurfactant, and oil) by electron beam irradiation. The mesophases can be doped by high concentrations of palladium (0.1 M) without any…

Elaboration, activity and stability of silica-based nitroaromatic sensors

D. Mercier, Franck Pereira, Christophe Méthivier, Pierre Montméat, Lionel Hairault, Claire-Marie Pradier

Functionalized silica-based thin films, modified with hydrophobic groups, were synthesized and used as sensors for nitroaromatic compound (NAC) specific detection. Their performance and behavior, in terms of stability, ageing and regeneration, have been fully characterized by combining chemical…

Dégradation chimique et mécanique de l'alumine en phase aqueuse : mécanisme et inhibition en conditions ambiantes et hydrothermales, Chemical and mechanical degradation of alumina in aqueous phase : mechanism and inhibition in ambient and hydrothermal conditions

Jane Abi Aad

L'alumine, utilisée comme support de catalyseurs pour la réaction de Fischer-Tropsch ou pour la conversion de la biomasse, se transforme partiellement en présence d'eau en phases (oxy)hydroxydes à l'origine de fines qui posent problème dans la mise en ¿uvre de procédés en réacteurs…, Alumina, used as a catalyst support for the Fischer-Tropsch reaction or for the conversion of biomass, partially transforms in presence of water into (oxy)hydroxides phases. The formation of the latter leads to the production of fine particles that may cause plugging problems in the implementation…
