Hydrodechlorination of 1,2-dichloroethane on nickel loaded Beta zeolite modified by copper: Influence of nickel and copper state on product selectivity

Rafal Baran, Anna Srebowata, Sandra Casale, D. Łomot, Stanislaw Dzwigaj

Influence of copper addition to nickel containing zeolite on activity and product selectivity in the hydrodechlorination of 1,2-dichloroethane was investigated. Ni2.0SiBEA and Cu2.0Ni2.0SiBEA zeolites were prepared by a two-steps postsynthesis method which consist of (1) creation of vacant T-atom…

Drastic Au(111) Surface Reconstruction upon Insulin Growth Factor Tripeptide Adsorption

Vincent Humblot, Anne Vallee, Ahmed Naitabdi, Frederik Tielens, Claire-Marie Pradier

Adsorption of biomolecules at metal surfaces often creates two-dimensional ordering of the adlayers. However, metal substrate reconstruction is less commonly observed, unless upon annealing of the molecule−surface system. Here, we report on the drastic room-temperature reconstruction of the Au(111…

Pseudoaneurysm of anterior tibial artery following a diaphyseal fracture ă of the tibia mimicking a malignant bone tumor

Pierre Sautet, Elie Choufani, Philippe Petit, Franck Launay, Jean-Luc Jouve, Sebastien Pesenti

Pseudoaneurysms of the lower limb are rare and frequently iatrogenics ă complications. Closed traumas are likely to generate lesions of the ă arterial wall, which generally become symptomatic at a later stage. The ă diagnosis of such vascular lesion is difficult because the ă symptomatology and the…

Rational design of a CO2-resistant toluene hydrogenation catalyst based on FT-IR spectroscopy studies

Julien Scalbert, Cécile Daniel, Yves Schuurman, Cyril Thomas, Frédéric C. Meunier

Rhodium highly dispersed on alumina becomes partly poisoned by strongly bound CO when used for toluene hydrogenation at 348 K in the presence of CO2. Operando FT-IR analysis enabled to observed CO(ads) build up over the sample, while no CO(gas) could be measured in the reactor effluent. Analyses…

Catalysis assisted by plasmon, Catalyse assistée par plasmon

Iyad Sarhid

Metallic nanoparticles (NPs) have many applications in catalysis. Some of them (gold, silver, copper) have a visible absorption resulting from the excitation of the surface plasmon by an external electromagnetic field. In this project, we propose to couple the catalytic properties of gold-based…, Les nanoparticules (NPs) métalliques ont de nombreuses applications en catalyse. Certaines d’entre elles (or, argent, cuivre) présentent une absorption dans le visible résultant de l’excitation du plasmon de surface par un champ électromagnétique extérieur. Nous proposons dans ce projet de coupler…

Formation of Activated Biomolecules by Condensation on Mineral Surfaces – A Comparison of Peptide Bond Formation and Phosphate Condensation

Thomas Georgelin, Maguy Jaber, Houssein Bazzi, Jean-François Lambert

Many studies have reported condensation reactions of prebiotic molecules, such as the formation of peptide bonds between amino acids, to occur to some degree on mineral surfaces. We have studied several such reactions on the same divided silica. When drying steps are applied, the equilibria of…

Introduction to Clay–Polymer Nanocomposites (CPN)

F Bergaya, Christian Detellier, Jean-François Lambert, G Lagaly

Clay mineral–polymer nanocomposites were described for the first time in 1993. Since that date, they were the subject of thousands of research papers. Clay mineral–polymer nanocomposites must be carefully distinguished from microcomposites and intercalated composites. The following chapters…

Conversion of syngas-derived C 2 + mixed oxygenates to C 3 –C 5 olefins over Zn x Zr y O z mixed oxide catalysts

Colin Smith, Vanessa Lebarbier Dagle, Matthew Flake, Karthikeyan K. Ramasamy, Libor Kovarik, Mark Bowden, Thomas Onfroy, Robert A. Dagle

In this study we report on a ZnxZryOz mixed oxide type catalyst capable of converting a syngas-derived C2+ mixed oxygenate feedstock to isobutene-rich olefins. Aqueous model feed comprising of ethanol, acetaldehyde, acetic acid, ethyl acetate, methanol, and propanol was used as representative…

Permanently hydrophilic, piezoelectric PVDF nanofibrous scaffolds promoting unaided electromechanical stimulation on osteoblasts

Maria Kitsara, Andreu Blanquer, Gonzalo Murillo, Vincent Humblot, Sara de Bragança Vieira, Carme Nogués, Elena Ibáñez, Jaume Esteve, Leonardo Barrios

Biomimetic functional scaffolds for tissue engineering should fulfil specific requirements concerning structural, biochemical and electro-mechanical characteristics, depending on the tissue that they are designed to resemble. In bone tissue engineering, piezoelectric materials based on poly(…

Adsorption of l-DOPA Intercalated in Hydrated Na-Saponite Clay: A Combined Experimental and Theoretical Study

K. El Adraa, V. Timon, J.-F. Lambert, Abdel-Rahman Al-Rabaa, F. Jaber, M. Jaber, Frederik Tielens

The intercalation of L-DOPA into the interlayer space of saponite, a 2:1 phyllosilicate, and the nature of host−guest interactions are investigated by a combined experimental and theoretical approach. L-DOPA zwitterions are accommodated vertically in the interlayer region as a bilayer of partially…
