Synthesis of small Ni-core–Au-shell catalytic nanoparticles on TiO2 by galvanic replacement reaction

Julien Reboul, Z. y Li, Jun Yuan, Kazuki Nakatsuka, Masakazu Saito, Kohsuke Mori, Hiromi Yamashita, Yu Xia, Catherine Louis

We report the first preparation of small gold–nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this…

PEDOT nanostructures synthesized in hexagonal mesophases

Srabanti Ghosh, Hynd Remita, Laurence Ramos, Alexandre Dazzi, Ariane Deniset-Besseau, Patricia Beaunier, Fabrice Goubard, Pierre-Henri Aubert, François Brisset, Samy Remita

We describe a single step preparation of nanostructures of poly(3,4-ethylenedioxythiophene), PEDOT, in the hydrophobic domains of cationic surfactant-based hexagonal mesophases via chemical oxidative polymerization of EDOT monomers using FeCl3 as an oxidizing agent. After polymerization, the…

Control of the anisotropic shape of cobalt nanorods in the liquid phase: from experiment to theory… and back

Kahina Aït Atmane, Carine Michel, Jean-Yves Piquemal, Philippe Sautet, Patricia Beaunier, Marion Giraud, Mickaël Sicard, Sophie Nowak, Rémi Losno, G. Viau

The polyol process is one of the few methods allowing the preparation of metal nanoparticles in solution. Hexagonal close packed monocrystalline Co nanorods are easily obtained in basic 1,2-butanediol at 448 K after a few minutes using a Co(II) dicarboxylate precursor. By using a combined…

Insight into the mechanism of action of temporin-SHa, a new broad-spectrum antiparasitic and antibacterial agent

Zahid Raja, Sonia André, Feten Abbassi, Vincent Humblot, Olivier Lequin, Tahar Bouceba, Isabelle Correia, Sandra Casale, Thierry Foulon, Denis Sereno, Bruno Oury, Ali Ladram

Antimicrobial peptides (AMPs) are promising drugs to kill resistant pathogens. In contrast to bacteria, protozoan parasites, such as Leishmania, were little studied. Therefore, the antiparasitic mechanism of AMPs is still unclear. In this study, we sought to get further insight into this mechanism…

Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…

The remarkable effect of the preparation procedure on the catalytic activity of CoBEA zeolites in the Fischer-Tropsch Synthesis

Karolina A. Chalupka, Sandra Casale, Ewa Zurawicz, Jacek Rynkowski, Stanislaw Dzwigaj

This work deals with the investigation of the influence of the preparation procedure and Co content on the activity of CoBEA zeolite in Fischer – Tropsch synthesis. For this purpose the Co-containing zeolites were prepared by a conventional wet impregnation (CoxAlBEA series) and a two-step…

Création de surfaces antibiofilms par greffage covalent de peptides et enzymes antibactériens sur les surfaces de cuivre et de titane, Creation of antibiofilm surfaces : covalent grafting of antimicrobial peptides and enzymes onto copper and titanium surfaces

Jessie Peyre

La contamination bactérienne et le développement de biofilms marins sont des problèmes récurrents, et terriblement coûteux sur les structures immergées des bâtiments de l'armée. L'emploi de composés bactéricides et nocifs pour l'écosystème est désormais interdit. Les travaux menés…, Bacterial contamination and formation of biofilms on immersed structures in seawater are frequent and at the origin of high cost maintenance treatments. The use of compounds biocidal, but also harmful for the ecosystem, is nowadays forbidden. The aim of this thesis work was to find new preventive…
