CO- and N2-FTIR Characterisation of Oxidised Rhodium Species Supported on Ce0.68Zr0.32O2

Céline Fontaine-Gautrelet, Jean-Marc Krafft, Olivier Gorce, Françoise Villain, Gérald Djéga-Mariadassou, Cyril Thomas

The identification of Rh oxidised species of a Rh(0.29)/Ce0.68Zr0.32O2 catalyst, exhibiting peculiar CO-O2 kinetics [Manuel et al., J. Catal. 2004, 224, 269], is addressed. For this purpose, various catalysts are studied by XANES, CO- and N2-FTIR, and benzene hydrogenation. The results obtained,…

Influence of the nature of the noble metal on the lean C3H6-assisted decomposition of NO on Ce0.68Zr0.32O2-supported catalysts

Cyril Thomas, Olivier Gorce, Françoise Villain, Gérald Djéga-Mariadassou

The Selective Catalytic Reduction (SCR) of NO assisted by C3H6 is investigated on Ce0.68Zr0.32O2 (CZ)-supported Platinum Group Metals (PGMs: Pd, Rh, Pt) catalysts. This study shows that the order of reactivity of the PGMs supported on CZ is: Pd Pt ≥Rh. The performances of the most active CZ-…

Unraveling the Mechanisms of Hypertrophy-Induced Matrix Mineralization and Modifications in Articular Chondrocytes

Ilhem Lilia Jaabar, Brittany Foley, Alberto Mezzetti, Françoise Pillier, Francis Berenbaum, Jessem Landoulsi, Xavier Houard

Chondrocyte hypertrophic differentiation is a main event leading to articular cartilage degradation in osteoarthritis. It is associated with matrix remodeling and mineralization, the dynamics of which is not well characterized during chondrocyte hypertrophic differentiation in articular cartilage.…

Co-grafting of amino-poly(ethylene glycol) and Magainin I on a TiO2 surface: tests of antifouling and antibacterial activities.

Jessie Peyre, V. Humblot, C. Méthivier, J.M. Berjeaud, C.-M. Pradier

An antimicrobial peptide, Magainin I (Mag), was grafted to a titanium oxide surface, via an antiadhesive poly(ethylene glycol) (PEG) cross-linker. The latter plays a 2-fold part, being antiadhesive, and enabling the covalent immobilization of the peptide. The functionalization was characterized at…

Building the uracil skeleton in primitive ponds at the origins of life: carbamoylation of aspartic acid

Louis Ter-Ovanessian, Jean-François Lambert, Marie-Christine Maurel

Abstract A large set of nucleobases and amino acids is found in meteorites, implying that several chemical reservoirs are present in the solar system. The “geochemical continuity” hypothesis explores how protometabolic paths developed from so-called “bricks” in an enzyme-free prebiotic world and…

Preparation of amorphous silica-aluminas with enhanced acidic properties and spectroscopic identification of their acid sites, Préparation de silice-alumines amorphes avec des propriétés acides améliorées et identification spectroscopique de leurs sites acides

Xiaojing Jin

ASAs with enhanced acidity and a higher fraction of acidic Al were prepared by two experimental strategies. Their textures have been investigated by N2 adsorption–desorption and their acidic properties by FTIR of adsorbed probe molecule (pyridine or CO). Besides, isomerization of 33DMB1 was…, Des silice-alumines (SA) avec des propriétés acides améliorées et une fraction plus élevée d’aluminium acides ont été préparées en utilisant deux stratégies de synthèse. Leurs propriétés texturales ont été étudiées par physisorption de N2 et leurs propriétés acides par suivi FTIR de l’adsorption de…
