Sintering and mass transport features of (Sn,Ti)O2 polycrystalline ceramics
(2003-05-01)
Different (Sn,Ti)O2 compositions were sintered at 1450 °C for 2 h with the purpose of investigating their sintering and mass transport properties. Highly dense ceramics were obtained and their structural properties studied ...
Propriedades magnéticas e resistência à corrosão de ligas com múltiplos componentes principais do sistema CuFeMnNiSnTi
(Universidade Federal de São Paulo, 2023-04-27)
O surgimento das chamadas ligas de alta entropia elevaram expressivamente o número de possibilidades para obtenção de novos materiais com diferentes aplicações, viabilizando sistemas anteriormente inviáveis ou pouco ...
In situ characterization of the effects of Nb and Sn on the anatase-rutile transition in TiO2 nanotubes using high-temperature X-ray diffraction
(Elsevier B.V., 2014-07-15)
New metastable p-type Ti alloys for biomedical applications containing biocompatible alloying elements such as Nb can present remarkable mechanical behavior. Whenever the performance of an implant produced from p-type Ti ...
Efeito da decoração de óxidos nanotubulares de TiO2 com Sn/SnOx na fotoeletrorredução do CO2
(Universidade Federal de São Paulo, 2021-09-01)
A fotoeletrorredução catalítica tem mostrado ser uma alternativa para a conversão do CO2 em compostos orgânicos com valor comercial agregado, reduzindo a sua emissão na atmosfera. A eficiência desse processo e a seletividade ...
A theoretical analysis of the TiO2/Sn doped (110) surface properties
(Elsevier B.V., 2005-04-10)
We have used the periodic quantum-mechanical method with density functional theory at the B3LYP level in order to study TiO2/Sn doped (1 1 0) surfaces and have investigated the structural, electronic and energy band ...
