Rita Sassine

Ces travaux de thèse visent à développer de nouveaux catalyseurs associant les activités prometteuses des nanoparticules de Rh(0) et l'effet de confinement des supports mésoporeux pour des applications en hydrogénation asymétrique dans l'eau. Des particules ont été préparées par réaction…, This thesis aims to develop new catalysts combining Rh(0) nanoparticles with promising activities and the confinement effect of mesoporous materials for applications in asymmetric hydrogenation in water. Particles were prepared by the reaction of NaBH4 with RhCl3, directly, within silicic (SBA-15)…

Synthesis and Treatment Parameters for Controlling Metal Particle Size and Composition in Cu/ZnO MaterialsFirst Evidence of Cu3Zn Alloy Formation

Salim Derrouiche, Hélène Lauron-Pernot, Catherine Louis

This paper deals with the study of the conditions of obtention of small metal copper particles on ZnO using easy synthesis methods and activation treatments, which were found "efficient" for the preparation of copper particles on silica, that is, deposition-precipitation with urea and…

Effect of Ca-doping on microstructure and photocatalytic activity of ZnO nanoparticles synthesized by sol gel method

R. Slama, J. El Ghoul, K. Omri, A. Houas, L. El Mir, Franck Launay

We report the synthesis of Zn1−xCaxO nanoparticles prepared by a sol–gel processing technique for x ranging from 0 to 0.05. The structural, morphological and optical properties of the nanoparticles were investigated by X-ray diffraction, transition electron microscopy, UV measurements, and…

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…

Non-Hydroxyl Radical Species Production during Dark Air Oxidation of Alluvial Soils

Elora Bourbon, Frédéric Averseng, Pierre Le Pape, Thierry Allard, Fulvia Baratelli, Fabrice Alliot, Alexandre Gélabert, Valentine Rollot, Elodie Guigon, Jessica Brest, Sylvie Nélieu, Guillaume Morin

Natural environments subjected to hydrologically-driven redox fluctuations are regarded as propitious to contaminant degradation since they favor cyclic oxygenation of Fe(II)-minerals that produces oxidizing reactive species, such as the hydroxyl radical, OH • . However, the identity of these…

Fate of Organic Molecules in the Mars Regolith Under UV Radiation Deduced from the MOMIE Laboratory Experiment

Cyril Szopa, Patrice Coll, Fabien Stalport, Olivier Poch, Maguy Jaber, Jean-François Lambert, Laura Rouquette, Jérôme Lasne

Among bioindicators or biosigna- tures, organic molecules present on Mars could be re- trieved in the regolith near the surface due to erosion of rocks and gardening of the soil from meteorites bom- bardment through the Mars history. Once their, the organic molecules are submitted to the harsh…

Impact of Collagen Crosslinking on Dislocated Human Shoulder Capsules—Effect on Structural and Mechanical Properties

Pauline Cornette, Ilhem Jaabar, Vincent Dupres, Jean-David Werthel, Francis Berenbaum, Xavier Houard, Jessem Landoulsi, Geoffroy Nourissat

Classical treatments of shoulder instability are associated with recurrence. To determine whether the modification of the capsule properties may be an alternative procedure, the effect of crosslinking treatment on the structure and mechanical properties of diseased human shoulder capsules was…

Nanostructured Nickel Aluminate as a Key Intermediate for the Production of Highly Dispersed and Stable Nickel Nanoparticles Supported within Mesoporous Alumina for Dry Reforming of Methane

Leila Karam, Julien Reboul, Nissrine El Hassan, Jaysen Nelayah, Pascale Massiani

Two routes of preparation of mesoporous Ni-alumina materials favoring the intermediate formation of nanostructured nickel-aluminate are presented. The first one involves an aluminum containing MOF precursor used as sacrificial template to deposit nickel while the second is based on a one-pot…
