Role of Hydroxyl Groups in the Basic Reactivity of MgO : a Theoretical and Experimental Study

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Françoise Delbecq, Philippe Sautet, Michel Che

Clean (i.e., carbonate- and hydroxyl-free) and hydroxylated MgO surfaces of various morphologies were used to study the correlation between thermodynamic Brønsted basicity (evaluated by the deprotonation of methanol and propyne followed by FTIR) and basic reactivity (evaluated by the conversion of…

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…

Mechanism of RuO2 Crystallization in Borosilicate Glass: An Original in Situ ESEM Approach

Hassiba Boucetta, Renaud Podor, Lorenzo Stievano, Johann Ravaux, Xavier Carrier, Sandra Casale, S. Gossé, Amélie Monteiro, Sophie Schuller

Ruthenium, a fission product arising from the reprocessing of spent uranium oxide (UOX) fuel, crystallizes in the form of acicular RuO2 particles in high-level waste containment glass matrices. These particles are responsible for significant modifications in the physicochemical behavior of the…

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…

Investigation of ion-selective electrodes with neutral ionophores and ionic sites by EIS. I. Theory

Claude Gabrielli, Patrick Hemery, Pierre Letellier, Michele Masure, Hubert Perrot, Marie-Isabelle Rahmi, Mireille Turmine

Models of an ion selective electrode involving an ionophore and mobile sites in a membrane are proposed. The first model, called the phase boundary potential model, supposed thermodynamic equilibrium; it allows the concentrations of the various species to be calculated. Then, a kinetic model, which…
