The structural and the photoelectrochemical properties of ZnO–ZnS/ITO 1D hetero-junctions prepared by tandem electrodeposition and surface sulfidation: on the material processing limits

A. Brayek, S. Chaguetmi, M. Ghoul, I. Ben Assaker, R. Chtourou, P. Decorse, P. Beaunier, S. Nowak, F. Mammeri, S. Ammar

ZnO–ZnS 1D hetero-nanostructures were prepared by an easy and scalable processing route. It consists of ZnO nanorod electrodeposition on ITO substrate and surface sulfidation by ion exchange in an aqueous Na 2 S solution. Increasing the treatment contact time (t c) from 8 to 48 h involves different…

Co–Ru Nanoalloy Catalysts for the Acceptorless Dehydrogenation of Alcohols

Brandon Azeredo, Tayssir Ben Ghzaiel, Ning Huang, Kamila Kaźmierczak, Wenjie Shen, Guillaume Wang, Delphine Schaming, Patricia Beaunier, Philippe Decorse, Noémie Perret, Jennifer Peron, Marion Giraud, Carine Michel, Lorette Sicard, Jean-Yves Piquemal

The synthesis of Co–Ru bimetallic nanoparticles was performed by co-reduction of Co(II) and Ru(III) salts in octan-1-ol, acting both as a solvent and a mild reducing agent. The metal composition was varied in the entire range, from pure Co to pure Ru. Although Co and Ru are miscible in the bulk,…

Boronic species as promising inhibitors of the Staphylococcus aureus NorA efflux pump: Study of 6-substituted pyridine-3-boronic acid derivatives

Fanny Fontaine, Arnaud Héquet, Anne-Sophie Voisin-Chiret, Alexandre Bouillon, Aurélien Lesnard, Thierry Cresteil, Claude Jolivalt, Sylvain Rault

In response to the extensive use of antibiotics, bacteria have evolved numerous mechanisms of defense against antimicrobial agents. Among them, extrusion of the antimicrobial agents outside the bacterial cell through efflux pumps is a major cause of concern. At first limited to one or few…

Zn-Cu Alloy Nanofoams as Efficient Catalysts for the Reduction of CO 2 to Syngas Mixtures with a Potential-Independent H 2 /CO Ratio

Sarah Lamaison, David Wakerley, David Montero, Gwenaëlle Rousse, Dario Taverna, Domitille Giaume, Dimitri Mercier, Juliette Blanchard, Huan Ngoc Tran, Marc Fontecave, Marc Mougel

Alloying strategies are commonly used to design electrocatalysts that take on properties of their constituent elements. Herein, we explore the use of such a strategy to develop Zn-Cu alloyed electrodes with unique hierarchical porosity and tunable selectivity for CO2 vs. H + reduction. By varying…

Elaboration of a reusable immunosensor for the detection of staphylococcal enterotoxin A (SEA) in milk with a quartz crystal microbalance

Michèle Salmain, Mahsa Ghasemi, Souhir Boujday, Claire-Marie Pradier

An immunosensor with quartz crystal microbalance (QCM) detection operating in flow-through mode was set up for assaying staphylococcal enterotoxin A (SEA) in model buffer medium and in milk. This biosensor is label-free and operates in the direct format. Each step of construction of the sensing…

Influence of the state of iron on CO oxidation on FeSiBEA zeolite catalysts

Izabela Hnat, Ireneusz Kocemba, Jacek Rynkowski, Thomas Onfroy, Stanislaw Dzwigaj

The influence of the state of iron on the catalytic properties of FexSiBEA zeolite in the oxidation of CO was investigated. Various FexSiBEA zeolites (x = 0.6, 1.0, 4.0 and 10 wt%) were prepared by a two-step post synthesis method. The presence of Fe(III) in tetrahedral coordination for low Fe…
