Tuning Surface Chirality of Adsorbed Gly-Pro Dipeptide/Cu(110) by Changing its Chemical Form via Electrospray Deposition.

Christophe Méthivier, Hervé Cruguel, Dominique Costa, Claire-Marie Pradier, Vincent Humblot

By changing the Ultra High Vacuum (UHV) deposition method, classical sublimation versus electrospray ionization, one can tune the chemistry of a chiral dipeptide molecule (Gly-Pro, GP), when adsorbed on a Cu(110) surface, from anionic to zwitterionic, respectively. This chemical shift will…

ZnO oxygen vacancies formation and filling followed by in situ photoluminescence and in situ EPR

C. Drouilly, J.M. Krafft, F. Averseng, S. Casale, Delphine Bazer-Bachi, Céline Chizallet, V. Lecocq, H. Vezin, H. Lauron-Pernot, G. Costentin

Oxygen vacancies of zinc oxide were followed by photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. The green PL emission was associated with oxygen vacancies: its intensity is enhanced upon static thermal treatment under inert or under vacuum, whereas it decreases upon…

Insight into the Nature of the ZnO x Promoter during Methanol Synthesis

Remco Dalebout, Laura Barberis, Giorgio Totarella, Savannah Turner, Camille La Fontaine, Frank de Groot, Xavier Carrier, Ad van der Eerden, Florian Meirer, Petra de Jongh

Despite the great commercial relevance of zinc-promoted copper catalysts for methanol synthesis, the nature of the Cu–ZnOx synergy and the nature of the active Zn-based promoter species under industrially relevant conditions are still a topic of vivid debate. Detailed characterization of the…

Simple and Specific Grafting of Antibacterial Peptides on Silicone Catheters

Coline Pinese, Said Jebors, Cécile Echalier, Patricia Licznar-Fajardo, Xavier Garric, Vincent Humblot, Christophe Calers, Jean Martinez, Ahmad Mehdi, Gilles Subra

To fight against nosocomial infection initiated by colonization of medical devices, a strategy enabling the direct and fast functionalization of silicone surfaces is proposed. This strategy proceeds in a site-specific way using original hybrid silylated antibacterial peptides. This safe and up-…

Kinetic effects in dehydration, rehydration, and isotopic exchange of bacterial photosynthetic reaction centers

Marco Malferrari, Francesco Francia, Alberto Mezzetti, Giovanni Venturoli, Klaus Gerwert

BACKGROUND:In IR difference spectroscopy of proteins and biological systems, as in many other biophysical techniques, experiments at different hydration levels, and after H/D or H216O/H218O exchange are particularly important, for band assignment and for mechanistic studies. OBJECTIVE:Evaluate the…

Experimental and theoretical evidences of the influence of hydrogen bonding on the catalytic activity of a series of 2-hydroxy substituted quaternary ammonium salts in the styrene oxide/CO2 coupling reaction

Catarina Carvalho Rocha, Thomas Onfroy, Julien Pilmé, Audrey Denicourt-Nowicki, Alain Roucoux, Franck Launay

Among industrial applications of CO2, the formation of cyclic carbonates from epoxides offers relevant chemical potentialities. Here, various N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl)ammonium salts (HEA16X) associated with different counter-anions (X−) have been investigated as catalysts of the…

Mononuclear pseudo-tetrahedral V species of VSiBEA zeolite as the active sites of the selective oxidative dehydrogenation of propane

Karolina Chalupka, Cyril Thomas, Yannick Millot, Frédéric Averseng, Stanislaw Dzwigaj

This work reports on the investigation of the influence of the nature of the V species in the ODH of propane. For this purpose, VSiBEA catalysts, including framework and/or extra-framework V species, were synthesized via the two-step method by controlling the speciation of the V species of the…

An easy way to obtain thin gold film on silica glass substrate by chemical method

Anne-Félicie Lamic-Humblot, Sandra Casale, Cédric Leger, S. Alpérine, Catherine Louis

Physical methods of metal deposition under ultra-high vacuum conditions are currently used to manufacture electrically conductive surfaces. In the case of silica glass, a supplementary oxide layer is usually required to avoid the uncontrolled growth of metal nanoparticles on the surface. Here, we…
