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 ...
Inactivation and disposal of by-products from Mycobacterium smegmatis by photoelectrocatalytic oxidation using Ti/TiO2-Ag nanotube electrodes
(Pergamon-Elsevier B.V. Ltd, 2012-12-15)
TiO2 nanotubular array electrodes coated with 16% (w/w) Ag nanoparticles (Ti/TiO2-Ag) have shown excellent performance in the disinfection of water containing Mycobacterium smegmatis. Photoelectrocatalytic disinfection of ...

Desenvolvimento de materiais nanoestruturados processados pela técnica de Fiação por Sopro em Solução
(Universidade Estadual Paulista (Unesp), 2019-12-13)
A técnica de fiação por sopro em solução foi utilizada neste trabalho para a produção de fibras de PVDF/TiO2, PVDF/Ni, PVDF/Fe2O3@SiO2, TiO2/Ag e fibras puras de TiO2. Inicialmente, foi realizado um estudo sobre a influência ...
Microscale meshes of Ti3O5 nano- and microfibers prepared via annealing of C-doped TiO2 thin films
(2011)
A new technique to produce microscale Ti3O5 nano- and microfiber meshes is proposed. When a 3 wt% carbon-doped TiO2 film on Si(1 0 0) was annealed at 1000 °C in wet nitrogen (0.8%H2O), the amorphous TiO2 phase gave rise ...
Degradação de poluentes orgânicos utilizando filmes de TiO2 modificados com íons prata
(Universidade Estadual Paulista (Unesp), 2006-05-26)
O presente trabalho descreve a utilização de filmes de TiO2 e TiO2 modificados com prata, preparados pelo método sol-gel, na fotodegradação de fenol e fluidos de corte. Os filmes foram imobilizados em substratos de vidro ...
