Preparation of zinc oxide and poly-ethylene oxide composite membranes and their phase relationship
(Universidad Nacional de Colombia Sede Medellín, 2012)
Zinc oxide and organic polymer (poly-ethylene oxide) based nanocomposite membranes were prepared and their phase relationship investigated. The composites were characterized by XRD, Raman scattering, DSC, and impedance ...
Heterogeneous Water Oxidation: Surface Activity versus Amorphization Activation in Cobalt Phosphate Catalysts
(2015)
Is water oxidation catalyzed at the surface or within the bulk volume of solid oxide materials? This question is addressed for cobalt phosphate catalysts deposited on inert electrodes, namely crystallites of pakhomovskyite ...
Thickness dependence of crystalline structure of Al-doped ZnO thin films deposited by spray pyrolysis
(Elsevier, 2015-07)
In this work, we have investigated the influence of thickness on crystalline structure of Al-doped ZnO films. Transparent conducting oxide films were grown by the spray pyrolysis technique from precursors prepared via the ...
Non-parabolic intergranular barriers in tin oxide and gas sensing
(American Institute of Physics, 2012-07-30)
Chemoresistive properties of crystalline solids strongly depend on the concentration of stoichiometric defects. In the case of tin oxide, oxygen vacancies are a case in point of such kind of defects. We address the problem ...
