Probing the Binding Mechanism of Peptides on a Copper Surface: Multi layer Self-Assembly Promoted by Glutamate Residues

Christophe Methivier, Victor Lebec, Jessem Landoulsi, Claire-Marie Pradier

Short peptides interact strongly with copper surfaces We report here a full characterization on the Interaction of Gly-Pto and the Cu(110) surface: By combining infrared analysis with X-ray photoelectron spectroscopy, two binding centers have been identified: the carboxylate and the amino groups…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

In Situ Generation of Active Pd Nanoparticles within a Macroreticular Acidic Resin: Efficient Catalyst for the Direct Synthesis of Hydrogen Peroxide

Kohsuke Mori, Akihiro Hanafusa, Michel Che, Hiromi Yamashita

An acidic resin bearing SO3H functional groups within its reticular structure acts as an efficient support for the in situ formation of highly active Pd nanoparticles (NPs) responsible for the direct synthesis of hydrogen peroxide from H2 and O2. Characterization by means of X-ray absorption fine…

Monitoring of the state of silver in porous oxides during catalyst preparation

Elie Sayah, Dalil Brouri, Anne Davidson, Pascale Massiani

Silver-supported porous oxides are promising heterogeneous catalysts for air treatment. Classical ways of prepn. are incipient wet impregnation or ion exchange (in case of zeolites) of a support with silver nitrate. Nevertheless, this precursor is known for its photosensitivity. The latter can lead…

Adsorption of Amino Acids and Peptides on Metal and Oxide Surfaces in Water Environment: A Synthetic and Prospective Review

D. Costa, L. Savio, Claire-Marie Pradier

Amino acids and peptides are often used as “model” segments of proteins for studying their behavior in various types of environments, and/or elaborating functional surfaces. Indeed, though the protein behavior is much more complex than that of their isolated segments, knowledge of the binding mode…

Incorporation of vanadium into the framework of hydroxyapatites: importance of the vanadium content and pH conditions during the precipitation step

Sarah Petit, Thrimurthulu Gode, Cyril Thomas, Stanislaw Dzwigaj, Yannick Millot, Dalil Brouri, Jean-Marc Krafft, Gwenaelle Rousse, Christel Laberty-Robert, Guylène Costentin

Even though vanadium-modified hydroxyapatite (V-HAp) samples are very promising systems for oxidative dehydrogenation of propane, the incorporation of vanadium into the hydroxyapatite framework was reported to be limited and to lead to over-stoichiometric compounds. Here, the synthesis of a Ca10(…
