Should W Surface Density of WOx-ZrO2 Catalysts Be Calculated With Respect To the Specific Surface Area of the Sample or That of ZrO2 Only?

Cyril Thomas

On the basis of the critical analysis of the NOx-TPD data obtained on WOx-ZrO2 samples [Law, H. Y.; Blanchard, J.; Carrier, X.; Thomas, C. J. Phys. Chem. C 2010, 114, 9731], this work provides convincing arguments for the first time upon which calculation of W surface density should be done by…

Development of acidic sites in WOx/ZrO2

Thomas Onfroy, Guillaume Clet, Marwan Houalla

Evidence is shown of the appearance of Brønsted acidic sites in WOx/ZrO2 at a given W loading and of a direct correlation between the abundance of ‘strong’ Brønsted acidic sites in these catalysts and propan-2-ol decomposition activity.

Ionic liquids as environmentally friendly corrosion inhibitors : the inhibition of mechanism of butylammonium nitrate for Al AA2024-T6

Oumaïma Gharbi, Abdelmoheiman Zakaria Benbouzid, Mai T.T. Tran, Mireille Turmine, Vincent Vivier

Ionic liquids are a promising class of solvent exhibiting a large panel of attractive physico-chemical properties, which can be of interest for energy, electrocatalysis or corrosion protection applications. Therefore, in the context of European restriction REACH regulation towards chromate-based…

Immobilisation of protein A on SAM's for the elaboration of immunosensors

Elisabeth Briand, Michèle Salmain, Chantal Compere, Claire-Marie Pradier

Binary mixtures of 11-mercaptoundecanoic acid (MUA) and other thiols of various lengths and terminal functions were chemisorbed on gold-coated surfaces via S-Au bonds to form mixed self-assembled monolayers (SAMs). Several values of the mole fraction of MUA in the thiol mixtures were tested and the…

Assessing the Oxidation Behavior of EC:DMC Based Electrolyte on Non- Catalytically Active Surface

Iban Azcarate, Wei Yin, Christophe Méthivier, François Ribot, Christel Laberty-Robert, Alexis Grimaud

The race for developing Li-ion batteries positive electrodes with always greater energy density has recently renewed interest towards understanding the formation of the so-called cathode electrolyte interface (CEI) forming upon cycling at high potential. In this work, we used an approach combining…

Heteroaggregation and Selective Deposition for the Fine Design of Nanoarchitectured Bifunctional Catalysts: Application to Hydroisomerization

Olfa Ben Moussa, Lionel Tinat, Xiaojing Jin, Walid Baaziz, Olivier Durupthy, Celine Sayag, Juliette Blanchard

We successfully prepared bifunctional catalysts with the distance between metallic and acid sites tuned at the nanometer scale. Sols of β-zeolite nanoparticles were synthesized and mixed in optimized conditions with a γ-AlOOH boehmite suspension to yield alumina/zeolite aggregates with a nanometer…

Metallomics in deep time and the influence of ocean chemistry on the metabolic landscapes of Earth's earliest ecosystems

Keyron Hickman-Lewis, Barbara Cavalazzi, Stéphanie Sorieul, Pascale Gautret, Frédéric Foucher, Martin Whitehouse, Heejin Jeon, Thomas Georgelin, Charles Cockell, Frances Westall

Modern biological dependency on trace elements is proposed to be a consequence of their enrichment in the habitats of early life together with Earth's evolving physicochemical conditions; the resulting metallic biological complement is termed the metallome. Herein, we detail a protocol for…

Hierarchical collagen-hydroxyapatite nanostructures designed through layer-by-layer assembly of crystal-decorated fibrils

Elodie Colaço, Dalil Brouri, Nesrine Aissaoui, Pauline Cornette, Vincent Dupres, Rute F Domingos, Jean-François Lambert, Emmanuel Maisonhaute, Karim El Kirat, Jessem Landoulsi

A comprehensive understanding of the mechanism by which type I collagen (Col) interacts with hydroxyapatite nanoparticles (Hap NPs) in aqueous solutions is a pivotal step for guiding the design of biologically relevant nanocomposites with controlled hierarchical structure. In this paper we use a…
