Développement d’un microsystème électrochimique pour l’étude de micro-objets circulants dans un canal microfluidique, Development of an electrochemical microsystem for the study of circulating micro-objects in a microfluidic channel

Ines Amokrane

Dans le cadre de cette thèse, l’objectif est de caractériser des micro-objets circulant dans un microcanal à l’aide de techniques électrochimiques. Dans le but de concevoir et de fabriquer un tel système, plusieurs méthodes et techniques sont nécessaires. Tout d’abord, le microsystème est constitué…, In this thesis, the aim is to characterise micro-objects flowing in a microchannel using electrochemical techniques. In order to design and fabricate such a system, several methods and techniques are required. Firstly, the microsystem consists of PDMS microchannels and thin film microelectrodes.…

Glutamic Acid Adsorption and Transformations on Silica

Meryem Bouchoucha, Maguy Jaber, Thomas Onfroy, Jean-François Lambert, Xue Baiyi

We report here on the adsorption and deposition of l-glutamic acid (Glu) on an amorphous silica and its subsequent thermal transformations. When adsorbed from aqueous solutions, Glu only has a low affinity for the silica surface but at high concentrations the adsorbed molecules serve as nuclei for…

A new method for elaborating mesoporous SiO 2 /montmorillonite composite materials

Khalil Tesnime Abou, Chaabene Semy Ben, Boujday Souhir, Blanchard Juliette, Bergaoui Latifa

We report the sol–gel preparation of SiO 2 / montmorillonite composite materials and the investigation of the effect of the amount of clay and the TEOS concentration on the textural and structural properties of the composites. Pre-swelling of the clay with cetyltrimethyl ammonium results in solids…

Effects of Pd on Catalysis by Au: CO Adsorption, CO Oxidation, and Cyclohexene Hydrogenation by Supported Au and Pd-Au Catalysts

Anthony Ward, Laurent Delannoy, Ruth Hahn, Shane Kendell, Christopher J. Pursell, Catherine Louis, Bert D. Chandler

catalysts has been shown to have beneficial effects on selective hydrogenation reactions, particularly 1,3- butadiene hydrogenation and the hydrogenation of nitroaromatics, especially p-chloronitrobenzene. Appropriate Pd incorporation enhances hydrogenation activity while maintaining the desirable…

Methanol Oxidation to Formaldehyde on VSiBEA Zeolite: A Combined DFT/vdW/Transition Path Sampling and Experimental Study

Diana C. Tranca, Frerich J. Keil, Ionut Tranca, Monica Calatayud, Stanislaw Dzwigaj, Maciej Trejda, Frederik Tielens

Density functional calculations have been performed applying periodic boundary conditions to investigate the oxidation of methanol on vanadium-containing SiBEA zeolite (VSiBEA). Different types of reaction configurations have been set up in conformity with the experimental conditions. Thermodynamic…

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…

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…
