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…

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…

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…

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-…

On the chemistry of the conversion coatings

Oumaïma Gharbi, Kevin Ogle, Junsoo Han

A conversion coating is an inorganic or organic–inorganic hybrid surface film conveying specific desirable functions to a material, formed by a spontaneous reaction between the material and an electrolyte. This chapter reviews the fundamental physical chemistry of the conversion coating process and…
