Characterization of metallic electrical contacts to SnO2 thin films lightly doped with Eu3+ ions, and photo-induced resistivity
(Materials Chemistry and Physics, 2012-06-15) [Artigo]
Lightly Eu3+-doped (0.05%) SnO2 thin films are deposited by the sol-gel-dip-coating technique, topped by alternative metallic layers of Al, Sn or In, arranged in a parallel layout on the thin film surface, and deposited ...
A continuously differentiable upwinding scheme for the simulation of fluid flow problems
(Applied Mathematics and Computation, 2012-05-01) [Artigo]
This paper deals with the numerical solution of complex fluid dynamics problems using a new bounded high resolution upwind scheme (called SDPUS-C1 henceforth), for convection term discretization. The scheme is based on TVD ...
Deposition and characterization of BiVO4 thin films and evaluation as photoanodes for methylene blue degradation
(Journal of Solid State Electrochemistry, 2012-10-01) [Artigo]
Thin films of bismuth vanadate (BiVO4) are deposited through the solution combustion synthesis technique coupled with the dip-coating process. Thermal gravimetric analyis shows a total mass loss of 71 % besides the formation ...
Photo-Induced Dipole Relaxation Current in Natural Amethyst
(Materials Research-ibero-american Journal of Materials, 2012-05-01) [Artigo]
Thermally stimulated depolarization current (TSDC) measurements were carried out for SiO2 in the amethyst form, aiming to investigate the relationship of observed current with relaxation phenomena related to quartz impurities. ...
