Intermittent dynamics of bubble dissolution due to interfacial growth of fat crystals

Irma Liascukiene, Gabriel Amselem, Jessem Landoulsi, Deniz Gunes, Charles Baroud

Foams are inherently unstable objects, that age and disappear over time. The main cause of foam aging is Ostwald ripening: smaller air bubbles within the foam empty their gas content into larger ones. One strategy to counter Ostwald ripening consists in creating armored bubbles, where solid…

Au-Ru/TiO2 prepared by deposition-precipitation with urea: Relevant synthesis parameters to obtain bimetallic particles

Lina Calzada, Catherine Louis, Chang Wan Han, Volkan Ortalan, Rodolfo Zanella

Although Au and Ru are not miscible in the bulk, the paper focusses on the attempts to prepare bimetallic Au-Ru/TiO2 catalysts by deposition-precipitation with urea (co-DPU and sequential DPU, Au then Ru and vice versa). Gold was found already reduced after the preparations of co-DPU and Ru then Au…

Silica-Supported Au-Ag Catalysts for the Selective Hydrogenation of Butadiene

Nazila Masoud, Laurent Delannoy, Christophe Calers, Jean-Jacques Gallet, Fabrice Bournel, Krijn P. de Jong, Catherine Louis, Petra E. de Jongh

Gold and silver are miscible over the entire composition range, and form an attractive combination for fundamental studies on bimetallic catalysts. Au–Ag catalysts have shown synergistic effects for different oxidation and liquid-phase hydrogenation reactions, but have rarely been studied for gas-…

Effect of Fe on the activity of Au/FeO x -TiO2 catalysts for CO oxidation

Mpfunzeni Raphulu, Thabang Ntho, Pumeza Gqogqa, John Moma, Lebohang Mokoena, Gary Pattrick, Mike Scurrell, Laurent Delannoy, Catherine Louis

A thorough characterisation of Au/TiO2 and Au/ FeOx-TiO2 catalysts was conducted in order to get a better understanding of the effect of Fe on the Au/TiO2 catalysts and link it to differences observed in their activities for CO oxidation. Several techniques including HRTEM, temperature-programmed…

Scanning Electrochemical Microscopy for Investigating Gas Bubble/Liquid Interfaces

Claude Gabrielli, François Huet, Michel Keddam, Philippe Rousseau, Vincent Vivier

Scanning electrochemical microscopy was used to characterize air bubble/electrolyte interfaces for bubbles of diameter in the millimeter range. Contrary to rigid insulated substrate/liquid interfaces, the approach of the tip of the microelectrode was shown to lead to a deformation of the bubble…
