    • closedAccess   New vanadium doped calcium titanate ceramic pigment 

      Gargori, Carina; Cerro Lloria, Sara; Galindo Llorach, Roberto; García López, Araceli; Llusar, Mario; Badenes March, José Antonio; Monrós, Guillermo Elsevier (2011-12)
      In this paper a new pink vanadium doped calcium titanate Ca(VxTi1−x)O3 ceramic pigment in conventional ceramic glazes is obtained by ceramic route and characterized. The limit of solid solution is near by x = 0.2, higher ...

    • closedAccess   Theoretical calculations on aseries of dinuclear vanadium and niobium clusters 

      Safont Villarreal, Vicent Sixte; Hernández Molina, Rita; Gili, Pedro; Sokolov, Maxim Elsevier (2011)
      Electronic structures of chalcogenide-bridged binuclear clusters of vanadium and niobium with the {M2(μ-Q2)2}4+, {M2(μ-Q)2}4+ and {M2(μ-Q)(μ-Q)2}4+ cores (Q = S, Se, Te) have been studied by density functional theory ...

    • closedAccess   Unraveling the Mechanisms of the Selective Oxidation of Methanol to Formaldehyde in Vanadia Supported on Titania Catalyst 

      González Navarrete, Patricio; Gracia, Lourdes; Calatayud Antonino, Mónica; Andres, Juan American Chemical Society (2010)
      A computational study based on B3LYP calculations was carried out to investigate the kinetic and mechanistic aspects of the selective oxidation of methanol to formaldehyde using titania-supported vanadate as a catalyst ...

    • closedAccess   Variations in vanadium, nickel and lanthanoid element concentrations in urban air 

      Moreno, T.; Querol, Xavier; Alastuey, Andres; De la Rosa, J.; Sánchez de la Campa, Ana María; Minguillón Bengochea, María Cruz; Pandolfi, Monica; González Castanedo, Yolanda; Monfort, Eliseo; Gibbons, Wes Elsevier (2010)
      The emission of trace metal pollutants by industry and transport takes place on a scale large enough to alter atmospheric chemistry and results in measurable differences between the urban background of inhalable particulate ...
