Combined theoretical and nanoscale experimental study of Pb(Ca,Ba)TiO3, Pb(Sr,Ba)TiO3, and Pb(Sr,Ca)TiO3complex perovskite structures: An investigation of the ferroelectric and electronic properties
(2017-01-01)
Combined experimental and first-principles studies have been conducted to obtain a fundamental understanding of the effect of A-site chemical doping on the electronic structure and ferroelectric behavior of Pb(Ca,Ba)TiO3, ...
TiO2 Coating of High Surface Area Silica Gel by Chemical Vapor Deposition of TiCl4 in a Fluidized-Bed Reactor
(American Scientific Publishers, 2011-09)
TiO2 was deposited on high surface area porous silica gel (400 m2g−1) in a fluidized bed reactor. Chemical vapor deposition was employed for the coating under vacuum conditions with TiCl4 as precursor. Nitrogen physisorption, ...
Evaluation of Ni0, NiO, and NiS as a Cocatalyst Modifier on TiO2Nanotubes Matrix for the Enhancement of Photoelectrocatalytic Oxidation of Penicillin G
(2021-07-01)
The development of an effective cocatalyst for the modification of TiO2 arrays has become highly desirable for the improvement of their photoelectrocatalytic properties. We investigated the modification of TiO2 with ...
Rietveld analysis of mechanically activated BaCO(3)-TiO(2) system
(J C P D S-int Centre Diffraction Data, 2008-06-01)
BaTiO(3) powders were prepared through mechanical activation chemistry and analyzed by Rietveld refinement with X-ray diffraction data. Raw BaCO(3) and TiO(2) powders were dry milled for 5 and 20 h and then calcinated for ...

Secondary phases in Nb-doped BaTiO3 ceramics
(Elsevier B.V., 2002-01-01)
In this work, the effect of Nb2O5 addition on the microstructure of BaTiO3 was studied. From XRD diagrams, a diminution in tetragonality parameters with an increase in dopant concentration was observed. In order to determine ...
Hydrothermal growth of BaTiO3 on TiO2 single crystals
(ELSEVIER SCIENCE BV, 2002-09-01)
The hydrothermal growth of polycrystalline BaTiO3 deposits on the surface of TiO2 rutile single crystals has been
studied with respect to the following parameters: (a) small quantities of Sr (1.0 and 0.04 at.%) in the ...
Comportamento eletroquímico do Ti2, Ti4, Ti4hard e Ti6Al4V em função de diferentes aplicações tópicas de flúor
(Universidade Estadual Paulista (Unesp), 2017-06-30)
Pacientes com reabilitações implantossuportadas parciais podem apresentar condições clínicas que necessitem de fluorterapia. Sabe-se que o fluoreto possui uma ação corrosiva em alguns metais, portanto o objetivo deste ...
