The influence of the Pt crystalline surface orientation on the glycerol electro-oxidation in acidic media
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
We investigated the electrochemical oxidation of glycerol on low-index Pt single crystals in acidic media (H2SO4 and HClO4) by cyclic voltammetry and Fourier Transform Infrared (FTIR) spectroscopy and we verified that this ...
Physical properties characterization ofW03 films grown by hot-filatnent metal oxide deposition
W03 is grown by hot-filament metal oxide deposition (HFMOD) technique under atmospheric pressure and an oxygen atmosphere. By X-ray diffraction obtains thatW03 presents mainly monoclinic crystalline phase. The chemical ...
Catalytic Behaviour of Mesoporous Cobalt-Aluminum Oxides for CO Oxidation
(Hindawi Publishing Corporation, 2014-10)
Ordered mesoporous materials are promising catalyst supports due to their uniform pore size distribution, high specific surface area and pore volume, tunable pore sizes, and long-range ordering of the pore packing. The ...
Thin titanium oxide films deposited by e-beam evaporation with additional rapid thermal oxidation and annealing for ISFET applications
(ELSEVIER SCIENCE BV, 2010)
Titanium oxide (TiO(2)) has been extensively applied in the medical area due to its proved biocompatibility with human cells . This work presents the characterization of titanium oxide thin films as a potential dielectric ...
Characterization of Zn0. 95Mn0.05O synthesized by polymeric precursors
This paper discusses the preparation and characterization of Zn 0.95Mn0.05O phase obtained by the polymeric precursor method for DMS applications. The as-obtained powders were calcined between 500 to 800°C and characterized ...
Photoluminescence in silicon/silicon oxide films produced by the Pulsed Electron Beam Ablation technique
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
In this work we report studies of the photoluminescence emission in samples based on Si/SiOx films deposited by the Pulsed Electron Beam Ablation (PEBA) technique. The samples were prepared at room temperature using targets ...
Ceramic behavior of ball clay with gadolinium oxide (Gd2O3) addition
(Elsevier Science, 2017-09)
The effect of the addition of gadolinium oxide (Gd2O3) in the thermal behavior of a (66%) kaolinitic ball clay was studied and compared with the pure clay. The incorporation of Gd2O3 is of technological interest for the ...
Organic matter and clay mineral crystallinity in soils of a topossequence on Basalt from Southern Brazil.
(In: MEETING OF THE INTERNATIONAL HUMIC SUBSTANCES SOCIETY, 17., 2014, Ioannina. Natural organic matter: structure-dynamics innovative applications: book of abstracts. Ioannina: University os Ioannina, 2014. p. 124-125., 2014)
Confinement effects on Titanium Oxide nanostructures.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
Titanium oxide is the most commonly used material for dye-sensitized solar cells. In such devices it is usually found as a nanostructured film, made by the agglomeration of several nanoparticles. The effects of nano-dimensionality ...
