Effect of la doping on the crystal structure, electric, magnetic and morphologic properties of the BSCCO system
(2017-10-01)
Studies of the doping process can provide a better understanding of the superconducting mechanisms in cuprous oxide materials. In this work, we studied the doping effects on the crystal structure, electric, morphologic and ...
Influência da dopagem com Cu2+ no TiO2 em suas propriedades fotocatalíticas
(Universidade Estadual Paulista (Unesp), 2017-03-16)
Devido à crescente industrialização e aumento populacional nos últimos anos, processos alternativos e ambientalmente limpos são pesquisados para controle no descarte de resíduos no ambiente. Dentre estes processos, a ...
Effect of viscosity and temperature on the microstructure of BBT thin films
(ABM, ABC, ABPol, 2003-06)
Thin films of BBT were deposited on silicate and Pt/Ti /SiO2 (111) substrates by spin- coating from the polymeric precursor method (Pechini process). The obtained films were characterized by optical microscopy, X-ray ...
Influence of oxygen flow on crystallization and morphology of LiNbO3 thin films
(Taylor & Francis Ltd, 2002-01-01)
Polymeric precursor solution (Pechini method) was used to deposit LiNbO3 thin films by spin-coating on (100) silicon substrates. X-ray diffraction data of thin films showed that the increase of oxygen flow promotes a ...
Effect of the composition on the thermal behaviour of the SrSn1-xTixO3 precursor prepared by the polymeric precursor method
(2013-03-15)
Strontium stannate titanate Sr(Sn, Ti)O3 is a solid solution between strontium stannate (SrSnO3) and strontium titanate (SrTiO3). In the present study, it was synthesized at low temperature by the polymeric precursor method, ...
Multi-layered LiNbO3 films prepared by a polymeric precursor method
(Elsevier B.V., 2001-01-01)
The polymeric precursor method was used to prepare multi-layered LiNbO3 films. The overall process consists of preparing a coating solution from the Pechini process and the deposited film is subsequently heat-treated. ...
Hot-pressed 9.5/65/35 PLZT prepared by the polymeric precursor method
(Elsevier B.V., 2000-01-01)
A 9.5/65/35 PLZT ceramic with a Pb-0.905 La-0.095 (Zr-0.65 Ti-0.35)(0.976) O-3 + 35 w% PbO formula was prepared using the Pechini method for powder preparation and two-step sintering in an oxygen atmosphere. Thr first step ...
