Adsorption and thermal condensation mechanisms of amino acids on oxide supports : I. Glycine on silica

Ming Meng, Lorenzo Stievano, Jean-François Lambert

Glycine was adsorbed on the surface of a well-defined silica from aqueous solutions of variable concentrations and pHs. The adsorbed molecules were characterized using middle-IR and UV-vis-NIR spectroscopies. Except at the lowestpH(2.0), they were predominantly present on the surface as zwitterions…

Additive-Free Aqueous Phase Synthesis of Formic Acid by Direct CO 2 Hydrogenation over a PdAg Catalyst on a Hydrophilic N-Doped Polymer–Silica Composite Support with High CO 2 Affinity

Shinya Masuda, Kohsuke Mori, Yasutaka Kuwahara, Catherine Louis, Hiromi Yamashita

A series of N-doped polymer containing silica (NPS) materials were synthesized via condensation reactions of 3-aminopropyltriethoxysilane (APT) and various aldehydes. These materials were assessed as supports for a PdAg alloy catalyst intended to promote the CO2 hydrogenation reaction under…

Petit Voyage vers la surface : Structure et réactivité de solides inorganiques, A small trip to the surface: structure and reactivity of inorganic solids

Lorenzo Stievano

Dans ma carrière, j'ai eu la chance et le privilège de m'attaquer à des problématiques scientifiques très variées, qui peuvent être ressemblées par le concept fédérateur de l'application de méthodes d'analyses physico-chimiques pour la compréhension de la structure et de la…

Stabilization of ribofuranose by a mineral surface

Thomas Georgelin, Maguy Jaber, Frederic Fournier, Guillaume Laurent, France Costa-Torro, Marie-Christine Maurel, Jean-François Lambert

The existence of the ribose moiety in biomolecules poses two problems for prebiotic chemistry. First, the exclusive presence of the furanose isomer in RNA has to be accounted for since furanose is a minor form in solution and does not exist in crystals. Second, all D-ribose polymorphs are unstable…

Selective Oxidation of Methane to Formaldehyde Catalyzed by Phosphates: Kinetic Description by Bond Strengths and Specific Total Acidities

Vasilij Gomonaj, Hervé Toulhoat

A kinetic model predicts the experimental activity and selectivity patterns obtained in oxidation of methane for divided unsupported orthophosphates (M II 3(PO4)2, M III PO4,) and pyrophosphates (M II 2P2O7, M IV P2O7) catalysts spanning extended ranges of M-O bond strength (calculated from first…

Gold/Polyoxometalate Core/Shell Nanoparticles for Combined Chemotherapy–Photothermal Cancer Therapy

Somia Tomane, Claire Wilhelm, Souhir Boujday, Alexandre Fromain, Antoine Miche, Flavien Bourdreux, Anne Dolbecq, Pierre Mialane, Anne Vallée

We designed monodisperse and perfectly shaped core/shell AuNP@Mo4Zol2Mn nanohybrids consisting of gold nanoparticles (AuNPs) functionalized by an antitumoral polyoxometalate (POM) incorporating the biologically active zoledronate ligand. After incubation, the nanoparticles were readily confined in…
