Biosensors elaborated on gold nanoparticles, a PM-IRRAS characterisation of the IgG binding efficiency.

Anne-Laure Morel, Souhir Boujday, Christophe Méthivier, Jean-Marc Krafft, Claire-Marie Pradier

This work is focused on studying the grafting of gold nanoparticles (Np) on a cystamine self-assembled monolayer on gold, in order to build sensitive immunosensors. The synthesis and deposition of gold nanoparticles, 13 and 55 nm sizes, were characterised by combining Polarisation Modulation…

A combined EXAFS and DFT study of the Ni2+ environment in dehydrated Ni/NaX

Hazar Guesmi, Pascale Massiani

The location of the divalent nickel cation exchanged in low amount in dehydrated NaX is identified by a combination of experimental (XAS) and theoretical (DFT) approaches. The Ni-O and Ni-T distances as well as the coordination numbers evaluated from experiments are in good agreement with the…

Effects of organic and inorganic treatment agents on the formation of conversion layer on hot-dip galvanized steel: An X-ray photoelectron spectroscopy study

S. Le Manchet, D. Verchere, Jessem Landoulsi

The formation of a Cr-free conversion layer on hot-dip galvanized (HDG) steel involves various interfacial processes which radically influence the composition of the coating and thus its performance. Here, we investigate the role of the main constituents contained in the treatment bath, the…

The past, present and future of heterogeneous catalysis

Ioana Fechete, Ye Wang, Jacques Vedrine

This review highlights key catalytic discoveries and the main industrial catalytic processes over the last 300 years that involved commodities, fine chemicals, petrochemicals, petroleum transformation for fuels and energy supply, emission control, and so forth. In the past, discoveries have often…

Enhanced selective nitroarene hydrogenation over Au supported on b-Mo2C and b-Mo2C/Al2O3

Noemie Perret, Xiaodong Wang, Laurent Delannoy, Claude Potvin, Catherine Louis, Mark A. Keane

b-Mo2C and b-Mo2C/Al2O3 have been synthesised via temperature programmed carburisation and employed, for the first time, as supports for gold catalysts. 1%w/w Au/Mo2C and Au/Mo2C/Al2O3 were prepared by deposition-precipitation with urea and used to promote the gas phase hydrogenation of para-…

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…

BSA adsorption on aliphatic and aromatic acid SAMs: Investigating the effect of residual surface charge and sublayer nature

Anne Vallée, Vincent Humblot, Rana Al Housseiny, Souhir Boujday, Claire-Marie Pradier

n this work, the influence of surface charge and layer rigidity on Bovin Serum Albumin (BSA) adsorption has been investigated. To this aim, Self Assembled Monolayers (SAMs) bearing terminal COOH or COO− groups were built on gold surfaces. The rigidity of the acid terminated SAMs was modified using…

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…
