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…

Structure and Surface Study of Hydroxyapatite-Based Materials: Experimental and Computational Approaches

Guylène Costentin, Christophe Drouet, Fabrice Salles, Stéphanie Sarda

In addition to designing catalytic materials ever more active and selective, the emergence of new classes of greener catalysts remains very challenging. The apatite family system with hydroxyapatite (HA) structure appears as a good candidate for catalysis due to its eco-compatibility properties,…

Influence of Coadsorbed Water and Alcohol Molecules on Isopropyl Alcohol Dehydration on γ-Alumina: Multiscale Modeling of Experimental Kinetic Profiles

Kim Larmier, Andre Nicolle, Céline Chizallet, Nicolas Cadran, Sylvie Maury, Anne-Félicie Lamic-Humblot, Eric Marceau, Hélène Lauron-Pernot

Successfully modeling the behavior of catalytic systems at different scales is a matter of importance not only for a fundamental understanding but also for a more rational design of catalysts and a more precise definition of the kinetic laws used as inputs in chemical engineering. We have developed…

Etude du front de minéralisation du tissu osseux et des modèles biomimétiques associés, Study of the mineralization front in bone tissue and in biomimetic models

Marc Robin

Les travaux réalisés ont pour but de répondre à deux questions : comment le collagène s'organise-t-il dans l'os mature ? Comment la phase minérale de l'os se forme-t-elle et quel est l'effet de son environnement sur sa formation ? Nous avons étudié d'un point de vue…, This work aims to understand: How is reached the plywood architecture in bone? How is bone apatite formed and what is the effect of the environment on apatite formation? Thus, histological bone thin sections were investigated focusing on the interface between the osteoid and mature bone tissues.…

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.

Electrospray ionization: an efficient approach to deposit polymetallic molecular switches onto gold surfaces

Amina Benchohra, Christophe Méthivier, Jessem Landoulsi, David Kreher, Rodrigue Lescouëzec

Electrospray ionization (EI) deposition is proven efficient in obtaining monolayers of a polymetallic charge transfer complex onto gold surfaces. The molecule's integrity is monitored by PM-IRRAS and XPS. This approach broadens the perspective of molecular magnetic switches' deposition,…

Temporin-SHa peptides grafted on gold surfaces display antibacterial activity

Andres Lombana, Zahid Raja, Sandra Casale, Claire-Marie Pradier, Thierry Foulon, Ali Ladram, Vincent Humblot

Development of resistant bacteria onto biomaterials is a major problem leading to nosocomial infections. Antimicrobial peptides are good candidates for the generation of antimicrobial surfaces because of their broad-spectrum activity and their original mechanism of action (i.e. rapid lysis of the…

Exploring the reactivity of mixed omega-functionalized undecanethiol self-assembled monolayers - A DFT study

Frederik Tielens, Vincent Humblot, Claire-Marie Pradier

The reactive sites of self-assembled monolayers (SAM) formed by substituted thiolalkyl chains have been predicted in the case of the pure mercaptoundecane acid, for the pure mercaptoundecane alcohol, and the mixed 1:1 SAMs. The differences in reactivity between the different SAM domains (pure and…
