Intérêt des revêtements N-halamines dans la lutte contre le développement des bactéries et du biofilm

Catherine Debiemme-Chouvy, Shan Gao, Hubert Cachet, Nadia Nazi, Vincent Humblot

L’enrayement du développement des biofilms ou de la prolifération de bactéries pathogènes est indispensable aussi bien pour des raisons de santé publique que pour des raisons économiques. Pour les milieux hydriques, à ces fins, des biocides oxydants sont fréquemment employés. Ils sont alors ajoutés…

Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis

Yang Song, Sandra Casale, Antoine Miche, David Montero, Christel Laberty-Robert, David Portehault

We synthesize metal silicide electrocatalysts for water oxidation, by using the high reactivity of silicon nanoparticles and the unique stability and low vapor pressure of molten salt solvents. We can then perform liquid-phase synthesis under vacuum at 300-400 C. This strategy yields FeSi, Ni 2 Si…

Deciphering the role and nature of phosphate species at the surface of stainless steel immersed in phosphoric acid solutions

I. Liascukiene, M. Ben Salah, Ph. Refait, L. Dhouibi, C. Methivier, J. Landoulsi, M. Jeannin

We investigate the evolution of the surface of a highly alloyed stainless steel (Sanicro 28) upon immersion in aqueous phosphoric acid solutions. For this purpose, both short-(few hours) and long-term immersion (several days) were carried out. A detailed analysis of XPS spectra allowed a…

Synthesis and characterization of Cr-ZSM-5 composite in fluoride medium and its performance in oxidation reaction of 2-mercaptobenzotiazole

Benchikh Imen, Djafri Fatiha, Djafri Ayada, Tabti Affaf, Franck Launay

Purpose The purpose of this paper is to synthesize Cr-ZSM-5 using hydrothermal synthesis in acidic fluoride medium and the investigation of its catalytic performance in heterogeneous oxidation of 2-mercaptobenzothiazole in the presence of H 2 O 2 . Design/methodology/approach The framework was…

A comparative study of the catalysis of peptide bonds formation by oxide surfaces

Jean-Francois Lambert, Maguy Jaber, Thomas Georgelin, Lorenzo Stievano

It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which…

Hydrodenitrogenation of indole over Mo2C catalyst: Insights into mechanistic events through DFT modeling

Witold Piskorz, Grzegorz Adamski, Andrzej Kotarba, Zbigniew Sojka, Céline Sayag, G. Djéga-Mariadassou

The molecular reaction mechanism of hydrodenitrogenation of indole was studied using density-functional theory calculations of the adsorbed o-ethylaniline surrounded by mobile hydrogen atoms. It was found that the hydrogenation of o-ethylaniline occurs through two steps: consisting in…

Direct Observation of the Surface Topography at High Temperature with SEM

Renaud Podor, X. F Le Goff, Joseph Lautru, H.P. Brau, Mathias Barreau, Xavier Carrier, Jerôme Mendonça, Dorian Nogues, Antoine Candeias

High-temperature scanning electron microscopy allows the direct study of the temperature behavior of materials. Using a newly developed heating stage, tilted images series were recorded at high temperature and 3D images of the sample surface were reconstructed. By combining 3D images recorded at…
