Surface chemistry and surface reactivity of fibrous amphiboles that are not regulated as asbestos

M. Fantauzzi, M. Pacella, J. Fournier, A. Gianfagna, G. B. Andreozzi, A. Rossi

Three fibrous amphiboles that are not regulated as asbestos--two from Biancavilla (Sicily, Italy) and one from Libby (MT, USA)--were studied in order to establish relationships between surface chemistry and surface reactivity. The three fibrous samples, plus one prismatic fluoro-edenite from…

Ring-closure on the Rocks in a Prebiotic Environment

Louis M P Ter-Ovanessian, Marie-Christine Maurel, Jean-François Lambert

Ring-closure is a key step in current pyrimidine anabolism and one may wonder whether cyclisation reactions could be promoted in the geochemical context at the origins of life, i.e. with the help of minerals. Various prebiotic minerals were tested in this work, including silica, carbonates,…

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…

Ce travail s’est focalisé sur l’apport des nanoparticules d’or (GNPs) dans la construction d’immunocapteurs piézoélectriques et plasmoniques. Deux stratégies ont été mises en œuvre, mettant à profit les propriétés physico-chimiques uniques des GNPs La première approche a consisté à nanostructurer…, This project focussed on the asset of gold nanoparticles (GNPs) in the build up of piezoelectric and plasmonic immunosensors. Two strategies were implemented, taking advantage of the unique physico-chemical features of GNPs. The first approach consisted in nanostructuring the surface of…

On the radical cracking of n-propylbenzene to ethylbenzene or toluene over Sn/Al2O3-Cl catalysts under reforming conditions

S Toppi, C Thomas, C Sayag, D Brodzki, Katia Fajerwerg, F Lepeltier, C Travers, G Djegamariadassou

Two series of chlorided-alumina-supported Sn catalysts were synthesized with different precursors, SnCl2 or SnBu4, and with various contents of Sn. The acidity of the catalysts including 0.2 wt% Sn was characterized by FTIR adsorption–desorption of 2,6-dimethylpyridine (Brønsted acidity) and…

Basic Cs-Pt/MCM-41 Catalysts: Synthesis, Characterization and Activity in n-Hexane Conversion

J. Blanchard, Katia Fajerwerg, M. Breysse, P. Beaunier, M.F. Ribeiro, J.M. Silva, P. Massiani

Cs-Pt/MCM-41 catalysts with basic character have been prepared by selective adsorption of Pt(NH3)4(OH)2 at pH = 8 on pure silica MCM-41 followed by incipient-wetness impregnation of CsNO3, then oxidation and reduction. The influence of the amount of Cs (0, 2 and 4 wt%) on the size of the reduced Pt…
