On the corrosion resistance of the CoCrFeMnNi high entropy alloys in chloride-containing sulfuric acid solutions

Yaojun Hou, Baojie Dou, Chenyang Xie, Fan Sun, Stéphane Rioual, Benoit Lescop, Kevin Ogle, Antoine Miche, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

The electrochemical reactivity of the high entropy Cantor alloy (CoCrFeMnNi) was investigated via potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), and surface analysis as a function of chloride content, in sulfuric acid solutions. The results revealed that…

Les Hydroxyapatites, un système basique atypique modulable par la synthèse : vers l'identification des sites actifs, Hydroxyapatites, an atypical basic system tuneable by synthesis: toward the identification of active sites

Sarah Diallo Garcia

Les Hydroxyapatites (HAp) sont des matériaux basiques dont les propriétés catalytiques atypiques, notamment leur très bonne sélectivité pour la transformation de l'éthanol en n-butanol, sont encore mal rationnalisées. La modulation de leur paramètres de synthèse ainsi leur aptitude à la…, Hydroxyapatites (HAp) are basic materials whose atypical catalytic properties, in particular their high selectivity in n-butanol from ethanol's conversion, are yet to be rationalised. Modulation of their synthesis parameters as well as their ability toward substitution allowed us to use their…

Miniaturized Pathogen Detection System Using Magnetic Nanoparticles and Microfluidics Technology

Benjamin Garlan, Amine Rabehi, Kieu Ngo, Sophie Neveu, Reza Askari Moghadam, Hamid Kokabi

Rapid detection of a biological agent is essential to anticipate a threat to the protection of biodiversity and ecosystems. Our goal is to miniaturize a magnetic pathogen detection system in order to fabricate an efficient and portable system. The detection device is based on flat, multilayer coils…

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…

Deciphering the Adsorption Mechanisms of RGD Subunits: L-Aspartic Acid on Cu(110)

Roberta Totani, Christophe Méthivier, Hervé Cruguel, Claire-Marie Pradier, Vincent Humblot

In this work we present a detailed surface science characterization of L-Aspartic acid adsorption on a Cu(110) surface. We replaced the traditional sublimation method to obtain molecular films by dosing aspartic acid directly from an aqueous solution through an Electrospray Ionization (ESI) device…

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(…

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…

Novel non-noble bimetallic Cu-Zn/TiO 2 catalysts for selective hydrogenation of butadiene

Zhao Wang, Guillaume Wang, Catherine Louis, Laurent Delannoy

Oxide-supported copper catalysts are active for the selective hydrogenation of polyunsaturated hydrocarbons with high selectivity to alkenes formation, but a low catalytic stability limits its application. The goal of the work was to investigate whether alloying Cu with Zn will improve catalyst…
