Surface-dependent sulfidation and orientation of MoS 2 slabs on alumina-supported model HDS catalysts

Cédric Bara, Anne-Félicie Lamic-Humblot, Emiliano Fonda, Anne-Sophie Gay, Anne-Lise Taleb, Elodie D Devers, Mathieu D Digne, Gerhard D Pirngruber, Xavier Carrier

The constant improvement of hydrotreating (HDT) catalysts, driven by industrial and environmental needs, requires a better understanding of the interactions between the oxide support (mostly alumina) and the MoS2 active phase. Hence, this work addresses the support-dependent genesis of MoS2 on four…

Direct AFM force mapping of surface nanoscale organization and protein adsorption on an aluminum substrate

Jessem Landoulsi, V. Dupres

We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity,…

Conducting polymer nanofibers with controlled diameters synthesized in hexagonal mesophases

Srabanti Ghosh, Laurence Ramos, Samy Remita, Alexandre Dazzi, Ariane Deniset-Besseau, Patricia Beaunier, Fabrice Goubard, Pierre-Henri Aubert, Hynd Remita

Oil-swollen hexagonal mesophases resulting from the surfactant mediated self-assembly of a quaternary mixture of water, surfactant, co-surfactant, and oil, are versatile templates to synthesize anisotropic nanomaterials. Poly(diphenylbutadyine) (PDPB) polymer nanofibrous network structures were…

Effect of dealumination on the catalytic performance of Cr-containing Beta zeolite in carbon dioxide assisted propane dehydrogenation

Piotr Michorczyk, Kamila Zeńczak-Tomera, Barbara Michorczyk, Adam Węgrzyniak, Marcelina Basta, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

New active and selective catalysts for propane to propene dehydrogenation in assistance of CO 2 (CO 2-PDH) were prepared by chromium incorporation in siliceous SiBeta. The Cr-containing SiBeta zeolite catalysts were obtained by two-step postsynthesis preparation procedure which consist, in the…

UHV Deposition of the Gly-Pro Dipeptide on Cu(110) by Sublimation or Electrospray Ionization

Christophe Méthivier, Vincent Humblot, Claire-Marie Pradier

While most of the peptide adsorption studies, in vacuum, are achieved by sublimation, we demonstrate here the possible use of electrospray ionization (ESI) to deposit entire peptides, possibly surrounded by solvated ions, on a surface in ultra high vacuum (UHV) conditions. This paper is then…
