Design of Mixed PEO/PAA Brushes with Switchable Properties Toward Protein Adsorption

M.F. Delacroix, G.L. Huet, T. Conard, S. Demoustier-Champagne, Filip E. Du Prez, Jessem Landoulsi, C.C. Dupont-Gillain

Adsorption of proteins at interfaces is an ubiquitous phenomenon of prime importance. Layers of poly(ethylene oxide) (PEO) are widely used to repel proteins. Conversely, proteins were shown to adsorb deeply into brushes of poly(acrylic acid) (PAA), and their subsequent partial release could be…

Methane dry reforming over hydrotalcite-derived Ni–Mg–Al mixed oxides: the influence of Ni content on catalytic activity, selectivity and stability

Radosław Dębek, Monika Motak, Dorota Duraczyska, Franck Launay, Maria Elena Galvez, Teresa Grzybek, Patrick da Costa

Ni-containing hydrotalcite-derived catalysts were prepared using different Ni loadings (from ca. 4 to 60 wt%) at the same MII/MIII ratio equal to 3. The influence of the Ni content on the physico-chemical features of these catalysts was studied, as well as the influence of this parameter on their…

Influence of synthesis parameters of mesocellular silica foams doped by nickel on methane reforming by CO 2

M. Boutros, O. Daoura, Franck Launay, P. Massiani, N. El Hassan

New catalysts based on Ni(0) dispersed onto mesocellular silica foams (MCF) were prepared for Dry Reforming of Methane (DRM). Different synthesis methods of MCF supports (with and without using NH4F or n-butanol) were tested in order to study the influence of the textural properties of the support…

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…

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…
