Two new hybrid organic/inorganic copper(II)-oxovanadate(V) diphosphonates: [Cu-2(phen)(2)(O3PCH2PO3)(V2O5)(H2O)], H2O and [Cu-2(phen)(2)(O3P(CH2)(3)PO3)(V2O5)], C3H8. Synthesis, structure, and magnetic properties
(2006)
Two new hybrid organic/inorganic copper oxovanadium diphosphonates [Cu2(phen)2(O3PCH2PO3)(V2O5)(H2O)]·H2O (1) and [(Cu2(phen)2(O3P(CH2)3PO3)(V2O5)]·C3H8 (2) have been obtained by hydrothermal synthesis. The compounds are ...
Nickel catalysts supported on ZrO2, Y2O3-stabilized ZrO2 and CaO-stabilized ZrO2 for the steam reforming of ethanol: Effect of the support and nickel load
(ELSEVIER SCIENCE BV, 2008)
Catalysts with various nickel loads were prepared on supports of ZrO2, ZrO2-Y2O3 and ZrO2-CaO, characterized by XRD and TPR and tested for activity in ethanol steam reforming. XRD of the supports identified the monoclinic ...

Fabrication and upconversion luminescence of Er3+/Yb 3+ codoped TeO2-WO3-Na2O-Nb 2O5-Al2O3 glass fibers
(Journal of Luminescence Volume 134, February 2013, Pages 528-532, 2013-02)
The tellurite fibers based on glasses with the composition TeO 2-WO3-Nb2O5-Na2O-Al 2O3-Er2O3-Yb2O 3 were fabricated by the rod-in-tube technique using a Heathway drawing tower. The upconversion luminescence of Er3+/Yb3+ ...
