Nano-engineered hierarchical porous silicas for enhanced catalytic efficiency in the liquid phase

Abdelali Zaki, M. Wastiaux, Sandra Casale, Alexandre Mussi, Jean-François Dhenin, Christine Lancelot, Jean-Philippe Dacquin, Pascal Granger

By tailoring the pore properties (size, morphology and orientation) of hierarchical catalysts, we show experimentally the importance of active phase accessibility on catalytic efficiency. This finding likely contributes to a better rationalisation of the structure sensitivity of the nitrite…

Atomic level characterization and sulfur resistance of unsupported W2C during dibenzothiophene hydrodesulfurization. Classical kinetic simulation of the reaction

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Céline Sayag, Patricia Beaunier, Gérald Djéga-Mariadassou

The stability of unsupported W2C tungsten carbide and its sulfur resistance during hydrodesulfurization (HDS) of dibenzothiophene (DBT) are a specificity of W2C. This material was characterized by X-ray diffraction, specific surface area measurements, HRTEM associated with EDS, lattice images,…

Bio-inspired calcium phosphate mineralization through enzymatic approach, Minéralisation de phosphate de calcium d'inspiration biologique par approche enzymatique

Jihye Lee

Biomineralization of calcium phosphate (CaP) is the process by which some organism builds hard mineralized tissues, such as bone, enamel and calcified cartilage. This process is regulated through various physicochemical factors and biochemical reactions, involving particularly matrix vesicles (MVs)…, La biominéralisation du phosphate de calcium (CaP) est le processus par lequel un organisme construit des tissus minéralisés durs, tels que l'os, l'émail et le cartilage calcifié. Ce processus est régulé par divers facteurs physico-chimiques et réactions biochimiques, impliquant en…

Vibrational and electrical investigations of a uniaxially stretched polystyrene/carbon nanotube composite

Liliane Bokobza, Gilles Garnaud, Patricia Beaunier, Jean-Luc Bruneel

Multiwall carbon nanotube (MWCNT)/polystyrene (PS) composite materials were prepared in the absence and in the presence of a surfactant. TEM analysis reveals the formation of chains made of several nanotubes tied up together upon application of the surfactant while an almost random distribution is…

Influence of the grafting process on the orientation and the reactivity of azide-terminated monolayers onto silica surface

Nisreen Al-Hajj, Yannick Mousli, Antoine Miche, Vincent Humblot, Julien Hunel, Karine Heuze, Thierry Buffeteau, Emilie Genin, Luc Vellutini

Click chemistry is widely used in materials and surface science for its high efficiency, ease of use and high yields. Azide-terminated SAMs have been prepared successfully by using three different deposition methods (postfunctionalization and direct grafting by immersion as well as spin coating).…

Characterization and catalytic activity of Mn (salen) immobilized on silica by various strategies

Khalil Tesnime Abou, Chaaben Semy Ben, Boujday Souhir, Bergaoui Latifa

Different strategies were applied to prepare supported Mn(salen) on fumed silica and to explore the effect of the interaction nature between the active sites and the surface on the catalytic activity. Direct and multistep grafting methods were used: the silica surface was silylated and the metal…
