A microGC study of the deactivation process during conversion of methylbutynol on basic zeolites

Pascale Massiani, Jean-François Groust, Guylène Costentin, Laurent Teyssier

The initial deactivation occurring during conversion of methylbutunol on basic alkali-faujasite catalysts was studied by microGC. Both the product selectivity and the formation of water during the first minutes of run permit to conclude on the deactivation process and on the nature of the adsorbed…

Mechanism of Metal Oxide Nanoparticle Loading in SBA-15 by the Double Solvent Technique

Juliette van Der Meer, Isabelle Bardez-Giboire, Cyrille Albert-Mercier, Bertrand Revel, Anne Davidson, Renaud Denoyel

The interaction between SBA-15 mesoporous silica, alkane solvents, and water was studied to understand the mechanism of the so-called double solvent technique. This method facilitates the loading of the pores of SBA-15 with a metal oxide precursor soln., by prewetting the SBA-15 with an alkane. In…

Photocatalytic Easy Recovery of Orthophosphates Contaminants in Water Using Amberlite‐732 Cationic‐Resin Exchanged by Ce 3+ and Ce 3+ ‐Au 3+ Species

Phds. Nawel Rahmoune, Siham Barama, Anne Davidson, David Montero, Mohamed Selmane, Antoine Miche, Fouad Benaliouche, Akila Barama

This report discusses the efficiency of photo-recovery of orthophosphate anions in water under visible irradiation using materials containing amorphous carbon, ceria and gold-ceria species. Catalysts were obtained by the exchange of Amberlite-732 polymeric-resin with isolated Ce(III) and co-mixing…

Inelastic light scattering by long narrow gold nanocrystals: when size, shape, crystallinity and assembly matter

Hervé Portalès, Nicolas Goubet, Sandra Casale, Xiang Zhen Xu, Mostapha Ariane, Alain Mermet, Jeremie Margueritat, Lucien Saviot

We report the synthesis of long narrow gold nanocrystals and the study of their vibrational dynamics using inelastic light scattering measurements. Rich experimental spectra are obtained for monodomain gold nanorods and pentagonal twinned bipyramids. Their assignment involves diameter-dependent non…

Versatile Molten Salt Synthesis of Manganite Perovskite Oxide Nanocrystals and Their Magnetic Properties

Francisco Gonell, Naoual Alem, Peter Dunne, Guillaume Crochet,   Patricia Beaunier, Christophe Méthivier, David Montero, Christel Laberty, Bernard Doudin, David Portehault

Manganite perovskite oxides exhibit a wide range of properties relevant for catalysis, energy conversion and spintronics. Such behaviors can be deeply modified at the nanoscale where confinement and surface effects may prevail. Interesting properties could then emerge from manganite perovskite…

Pulsed field gradient NMR studies of n-hexane diffusion in MCM-41 materials

Ziad Adem, Flavien Guenneau, Marie-Anne Springuel-Huet, Juliette Blanchard, Antoine Gedeon

The knowledge of transport properties in heterogeneous catalysis is of important interest since the selectivity and the activity depend significantly on diffusion. Pulsed Field Gradient (PFG) NMR has proved to be a valuable tool to probe the intracrystalline diffusion of molecules adsorbed in…

One-pot synthesis of a new generation of hybrid bisphosphonate polyoxometalate gold nanoparticles as antibiofilm agents

S. Tomane, E. López-Maya, S. Boujday, V. Humblot, J. Marrot, N. Rabasso, J. Castells-Gil, C. Sicard, Anne Dolbecq, P. Mialane, A Vallée

A reduced polyoxovanadate functionalized with bisphosphonate molecules was synthesized and used to prepare in one step hybrid organic-inorganic polyoxometalate decorated gold nanoparticles. These new composites were shown to strongly inhibit P. aeruginosa and S. epidermidis biofilms growth, the…

Interaction of proteins with chemically controlled surfaces for biosensor development, Interactions des protéines avec des surfaces chimiquement contrôlées pour le développement de bio-senseurs

Victor Lebec

In this work we studied protein adsorption on chemically well-controlled surfaces. The focus is put on linking physico-chemical properties of surfaces (hydrophobicity/charge) to the structural properties of the adsorbed proteins. To this end, alkyl thiols differing by their end group were used to…, Dans ce travail, nous étudions l’adsorption de protéines sur des surfaces chimiquement contrôlées. Le but est d’établir le lien entre les propriétés physico-chimiques de la surface (hydrophobicité /charge) et la structure physique de protéines. Des couches auto-assemblées de thiols ayant des…
