Self-Organization and/or Nanocrystallinity of Co Nanocrystals Effects on the Oxidation Process Using High-Energy Electron Beam

Ana Cazacu, Claudio Larosa, Patricia Beaunier, Guillaume Laurent, Paolo Nanni, Liliana Mitoseriu, Isabelle Lisiecki

We report the enhanced stability of Co nanocrystals (NCs) when they are highly ordered at both nanometer and micrometer scales. We show for the first time that both the crystalline structure of Co nanoparticles (NPs) and their 2D hexagonal organization have a significant impact on the oxidation…

Facile synthesis of palladium nanowires by a soft templating method

Prem Siril, Anaïs Lehoux, Laurence Ramos, Patricia Beaunier, Hynd Remita

Very long and thin monocrystalline Pd nanowires were synthesized by decomposition using hydrazine vapour treatment of Pd2(DBA)3 confined in the oil phase of a hexagonal mesophase. The mesophase is composed of toluene-swollen tubes, doped with the Pd precursor, stabilized by a monolayer of…

Lipase-embedded Silica Nanoparticles with Oil-filled Core-Shell Structure: Stable and Recyclable Platforms for Biocatalysts

Yasutaka Kuwahara, Takato Yamanishi, Takashi Kamegawa, Kohsuke Mori, Michel Che, Hiromi Yamashita

Lipase enzyme was embedded within silica nanoparticles with oil-filled core-shell structure. The enzyme embedded within such architecture retained all of its activity and showed high catalytic performance both in water and in organic media with optimal stability and recyclability.

Amphiphilic block copolymer nano-fibers via RAFT-mediated polymerization in aqueous dispersed system

Stephanie Boisse, Jutta Rieger, Khaled Belal, Aurelie Di-Cicco, Patricia Beaunier, Min-Hui Li, Bernadette Charleux

Self-assembled block copolymer nanofibers are attractive materials for multiple applications. We propose here a novel, very simple and straightforward method to prepare polymeric nanofibers at high solids contents directly in water. It is based on an aqueous emulsion polymerization process…

The genesis of a heterogeneous catalyst: in situ observation of a transition metal complex adsorbing onto an oxide surface in solution

Antoine Hervier, Juliette Blanchard, Guylène Costentin, John R. Regalbuto, Catherine Louis, Souhir Boujday

Understanding the interactions between metal complexes and oxide surfaces is crucial to the synthesis of supported metal catalysts. Recently developed in situ techniques have made it possible to closely characterize the solid/liquid interface. For the first time, the adsorption of platinum…

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…

Optimization and Antibacterial Response of N-Halamine Coatings Based on Polydopamine

Nadia Nazi, Adeline Marguier, Catherine Debiemme-Chouvy, Vincent Humblot

RessouDue to the ability of microorganisms to first adhere to a material surface and then to lead to the formation of a biofilm, it is essential to develop surfaces that have antimicrobial properties. It is well known that N-halamine coatings allow us to prevent or minimize such phenomena. In the…

Co-grafting of amino-poly(ethylene glycol) and Magainin I on a TiO2 surface: tests of antifouling and antibacterial activities.

Jessie Peyre, V. Humblot, C. Méthivier, J.M. Berjeaud, C.-M. Pradier

An antimicrobial peptide, Magainin I (Mag), was grafted to a titanium oxide surface, via an antiadhesive poly(ethylene glycol) (PEG) cross-linker. The latter plays a 2-fold part, being antiadhesive, and enabling the covalent immobilization of the peptide. The functionalization was characterized at…
