Structural, dielectric, ferroelectric and optical properties of PBCT, PBST and PCST complex thin films on LaNiO3 metallic conductive oxide layer coated Si substrates by the CSD technique
(Elsevier B.V., 2014-10-05)
Ferroelectric thin films and LaNiO3 (LNO) metallic conductive oxide thin films were prepared by a chemical solution deposition (CSD) method. PBCT60, PBST60 and PCST60 ferroelectric thin films were grown on different ...
High-Pressure Assisted Sintering of Ti-20Si-10B and Ti-10Si-5B Powders
(Trans Tech Publications Ltd, 2012-01-01)
This work presents the structural characterization of Ti-10Si-5B and Ti-20Si-10B (at-%) alloys produced by high-pressure assisted sintering. Sintering was performed in air at 1100 and 1200 degrees C for 60 s using pressure ...

Formas de aplicação de silício e o seu efeito na mitigação da toxidez de zinco no milho
(Universidade Estadual Paulista (Unesp), 2021-08-31)
A contaminação do solo em áreas agrícolas vem sendo motivo de preocupação nas últimas décadas. Esta é causada pelo uso inadequado e descarte de resíduos industriais, fertilizantes, agroquímicos que contém elementos tóxicos ...
alpha-SiAlON ceramics with elongated grain morphology using an alternative sintering additive
(Elsevier B.V., 2004-04-01)
In this work, the use of a natural yttrium oxide and rare earth oxide solid solution (CRE2O3) as stabilizers of the alpha-Si3N4 phase to form alpha-SiAlON has been investigated. This oxide mix is produced at FAENQUIL-DEMAR, ...
NIR luminescence from erbium doped (100-x)SiO2:xZnO powders obtained by soft chemical synthesis
(2016-02-01)
We present the structural and optical results of (100-x)SiO2:xZnO compounds with x=0, 20, 40, 60, 80, and 100, containing 1 mol% of Er3+ prepared by a simple chemical route. It was evaluated the crystallization effect on ...
