Characterization of Phosphate Species on Hydrated Anatase TiO2 Surfaces

Frederik Tielens, Christel Gervais, Géraldine Deroy, Maguy Jaber, Lorenzo Stievano, Cristina Coelho Diogo, Jean-Francois Lambert

The adsorption/interaction of KH2PO4 with solvated (100) and (101) TiO2 anatase surfaces is investigated using periodic DFT calculations in combination with GIPAW NMR calculations and experimental IR and solid state 17O, and 31P NMR spectroscopies. A complete and realistic model has been used to…

Nanostructured and spiky gold in biomolecule detection: improving binding efficiencies and enhancing optical signals

E. E. Bedford, S. Boujday, C.-M. Pradier, F. X. Gu

Nanostructured gold can improve the ability to detect biomolecules. Whether planar nanostructured surfaces or nanostructured particles are used, similar principles governing the enhancement apply. The two main benefits of nanostructured gold are improved geometry and enhancement of optical…

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…

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…

Orange Carotenoid Protein in Mesoporous Silica: A New System towards the Development of Colorimetric and Fluorescent Sensors for pH and Temperature

Silvia Leccese, Andrea Calcinoni, Adjélé Wilson, Diana Kirilovsky, Donatella Carbonera, Thomas Onfroy, Claude Jolivalt, Alberto Mezzetti

Orange carotenoid protein (OCP) is a photochromic carotenoprotein involved in the photoprotection of cyanobacteria. It is activated by blue-green light to a red form OCPR capable of dissipating the excess of energy of the cyanobacterial photosynthetic light-harvesting systems. Activation to OCPR…

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…

Dégradation chimique et mécanique de l'alumine en phase aqueuse : mécanisme et inhibition en conditions ambiantes et hydrothermales, Chemical and mechanical degradation of alumina in aqueous phase : mechanism and inhibition in ambient and hydrothermal conditions

Jane Abi Aad

L'alumine, utilisée comme support de catalyseurs pour la réaction de Fischer-Tropsch ou pour la conversion de la biomasse, se transforme partiellement en présence d'eau en phases (oxy)hydroxydes à l'origine de fines qui posent problème dans la mise en ¿uvre de procédés en réacteurs…, Alumina, used as a catalyst support for the Fischer-Tropsch reaction or for the conversion of biomass, partially transforms in presence of water into (oxy)hydroxides phases. The formation of the latter leads to the production of fine particles that may cause plugging problems in the implementation…
