Biocidal Properties of a Glycosylated Surface: Sophorolipids on Au(111)

Claire Valotteau, Christophe Calers, Sandra Casale, Jan Berton, Christian V. Stevens, Florence Babonneau, Claire-Marie Pradier, Vincent Humblot, Niki Baccile

Classical antibacterial surfaces usually involve antiadhesive and/or biocidal strategies. Glycosylated surfaces are usually used to prevent biofilm formation via antiadhesive mechanisms. We report here the first example of a glycosylated surface with biocidal properties created by the covalent…

Evidence for emission and transfer of energy from excited edge sites of MgO smokes by photoluminescence experiments.

Romain Hacquart, Jean-Marc Krafft, Guylène Costentin, Jacques Jupille

New features are observed in photoluminescence spectra of MgO smokes produced in controlled conditions, an experiment inspired by previous measurements on cleaved MgO(100). Upon photoexcitation at 5.17–5.45 eV, most luminescence spectra observed can be decomposed into two bands, peaking at 3.82–3.…

Evolution of nickel speciation from aqueous solution to the surface of Ni/SiO2: effect of the number of chelating ligands in [Ni(en)x(H2O)6-2x]2+

Michel Che, Eric Marceau, Ke Qiang Sun

The evolution of nickel speciation during the successive preparation steps of Ni–SiO2 catalysts is studied by UV-Vis-NIR, FT-IR, DTG, TPR and TEM. The study focuses on the effect of the number of chelating ligands in the precursor complexes [Ni(en)x(H2O)(6 2x)]2+ (en = ethylenediamine, x = 1, 2, 3…

Zirconium-Substituted Isopolytungstates: Structural Models for Zirconia-Supported Tungsten Catalysts

Hugo Carabineiro, Richard Villanneau, Xavier Carrier, Patrick Herson, Francisco Lemos, Fernando Ramôa Ribeiro, Anna Proust, Michel Che

The synthesis and characterization of a series of mixed W-Zr polynuclear Lindqvist-type complexes, deriving from hexatungstate [W6O19]2-, are described in this work. This family of compounds is built from {W5O18Zr}2- moieties as shown by the X-ray structures of the monomeric [W5O18Zr(H2O)3-n(DMSO)n…

Mesoporous materials from zeolite seeds as supports for nickel-tungsten sulfide active phases: Part 2. Catalytic properties for deep hydrodesulfurization reactions

Juliette Blanchard, Shuangqin Zeng, Michèle Breysse, Yahua Shib, Xintian Su, Hong Nie, Dadong Li

The properties of nickel-tungsten sulfide supported on MCM-41 aluminosilicate materials assembled from beta-zeolite seeds ([beta]-MCM-41) were examined in the conversion of 4,6-dimethyldibenzothiophene (4,6-DMDBT) pure or in mixture with dimethyldisulfide, carbazole and tetralin. As reported in the…

Surface chemistry and surface reactivity of fibrous amphiboles that are not regulated as asbestos

M. Fantauzzi, M. Pacella, J. Fournier, A. Gianfagna, G. B. Andreozzi, A. Rossi

Three fibrous amphiboles that are not regulated as asbestos--two from Biancavilla (Sicily, Italy) and one from Libby (MT, USA)--were studied in order to establish relationships between surface chemistry and surface reactivity. The three fibrous samples, plus one prismatic fluoro-edenite from…

Partial oxidation of methane on NixAlBEA and NixSiBEA zeolite catalysts: Remarkable effect of preparation procedure and Ni content

Karolina A. Chalupka, Wojciech K. Jozwiak, Jacek Rynkowski, Waldemar Maniukiewicz Waldemar, Sandra Casale, Stanislaw Dzwigaj

This work reports on the investigation of the influence of the preparation procedure and Ni content on partial oxidation of methane to synthesis gas. For this purpose the Ni-containing zeolite catalysts were prepared by two different methods: a conventional wet impregnation method (NixAlBEA series…

Selective hydrogenation of butadiene over TiO2supported copper, gold and gold–coppercatalysts prepared by deposition–precipitation

Laurent Delannoy, Gode Thrimurthulu, Padigapati S. Reddy, Christophe Méthivier, Jaysen Nelayah, Benjaram M. Reddy, Christian Ricolleau, Catherine Louis

Oxide supported copper and gold catalysts are active for the selective hydrogenation of polyunsaturatedhydrocarbons but their low activity compared to palladium catalysts and the deactivation of copper catalystslimit their use. There are only a very limited number of studies concerned with the use…

Inorganic Phosphate and Nucleotides on Silica Surface: Condensation, Dismutation, and Phosphorylation

Thomas Georgelin, Maguy Jaber, Thomas Onfroy, Aaron-Albert Hargrove, France Costa-Torro, Jean-François Lambert

We explore the reactivity of inorganic monophosphate ions (Pi) and 5′-adenosine monophosphate (AMP), adsorbed onto amorphous silica separately or together. This question has relevance for prebiotic chemistry scenarios and, more generally, for biomedical applications involving biomolecule adsorption…
