Study of gold electrodissolution by scanning electrochemical microscopy in different modes

Divino Salvador Ramírez-Rico, Michel Keddam, Erika Roxana Larios-Durán, Vincent Vivier

The electrodissolution of gold has already been widely studied by several methods, but no consensus concerning the reaction mechanism has been reached. In this work, the scanning electrochemical microscopy (SECM) has been used in transient condition for studying the electrodissolution of gold in…

Successive Strong Electrostatic Adsorptions of [RhCl6]3– on Tungstated-Ceria as an Original Approach to Preserve Rh Clusters From Sintering Under High-Temperature Reduction

Jeffrey Miller, Neil Schweitzer, Mimoun Aouine, Philippe Vernoux, Abdelmalik Boufar, Juliette Blanchard, Jean-Marc Krafft, Christophe Méthivier, Céline Sayag, Frédéric Ser, Mickaël Sicard, Cyril Thomas

Supported transition metal materials have been identified as ideal candidates for decades to catalyze various reactions of interest in the fields of hydrocarbon refining, energy and environmental catalysis. As the resources in transition metals on earth are known to be limited, it appears to be of…

Cyto- and bio-compatibility assessment of plasma-treated polyvinylidene fluoride scaffolds for cardiac tissue engineering

Maria Kitsara, Gaëlle Revet, Jean-Sébastien Vartanian-Grimaldi, Alexandre Simon, Mathilde Minguy, Antoine Miche, Vincent Humblot, Thierry Dufour, Onnik Agbulut

As part of applications dealing with cardiovascular tissue engineering, drop-cast polyvinylidene fluoride (PVDF) scaffolds have been treated by cold plasma to enhance their adherence to cardiac cells. The scaffolds were treated in a dielectric barrier device where cold plasma was generated in a…

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…

Tunable laser interference lithography preparation of plasmonic nanoparticle arrays tailored for SERS

Nestor Gisbert Quilis, Médéric Lequeux, Priyamvada Venugopalan, Imran Khan, Wolfgang Knoll, Souhir Boujday, Marc Lamy de La Chapelle, Jakub Dostalek

The facile preparation of arrays of plasmonic nanoparticles over a square centimeter surface area is reported. The developed method relies on tailored laser interference lithography (LIL) that is combined with dry etching and it offers means for the rapid fabrication of periodic arrays of metallic…

Defect-related multicolour emissions in ZnO tetrapods: from violet, over green to yellow

Miao Zhang, Frédéric Averseng, Francia Haque, Patrizia Borghetti, Jean-Marc Krafft, Benoît Baptiste, Guylène Costentin, Slavica Stankic

The nature of defects in ZnO smoke was studied at different stages of the materials' history by combining photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. In contrast to studies previously reported on ZnO nanopowders, high vacuum conditions (P < 10-5 mbar)…
