Structural and thermal studies of titanium dioxide gel modified with anatase isostructural zircon silicate
(2018-01-01)
Important changes in anatase crystal structure are responsible for the consequent anatase-to-rutile phase transition in titanium dioxide powders. In order to investigate several structural rearrangements occurring in anatase ...
Toxicological evaluation of the TiO2 anatase and rutile crystalline phases in H9c2 cardiac cells
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12-05)
Although TiO2 particles constitute a highly used material in consumer products, including food and pharmaceutical industries, considerable experimental evidence suggests that TiO2 particle exposure could be harmful and ...
Study of the zirconium and silicon homovalent dopants insertion on the structure and bandgap energy of titanium dioxide powders
(2018-01-01)
The reconstructive transformation occurring during the anatase-to-rutile phase transition can be observed through adequate techniques such as Thermal Analyses and Z-ray diffractometry followed by structural refinement. The ...
Low Temperature Synthesis of Several Titanium Dioxide Solid Solutions through the Sol-Gel Method
(Univ Federal Mato Grosso Sul, Dept Quimica, 2018-01-01)
Titanium dioxide powders constituted by anatase single phase are very useful to understand several properties of that semiconductor applied as photocatalyst material. In addition, the reconstructive transformation involved ...
Effect of iron and vanadium on the phase transition of titanium dioxide obtained by polymeric precursor method
(2017-01-01)
The titanium dioxide phase formation is dependent on the synthesis method, temperature of calcination and modifiers insertion. By using chemical methods, such as Polymeric Precursor Method, the organic impurities or extrinsic ...
Estudo computacional das interações entre nanopartículas de dióxido de titânio envolvidas no processo de coalescência orientada
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-04-03)
Experimental and theoretical studies have shown that the aggregation of TiO2 anatase nanoparticles (NPs) occurs with preferential crystallographic orientation by the so-called oriented attachment mechanism (OA). The growth ...
Morphological and structural variations in anodic films grown on polished and electropolished titanium substrates
(2019-11-11)
The objective of this work was to investigate the effects of anodization parameters on the anatase phase formation of titanium oxide films, which have been grown on both electropolished and nonelectropolished titanium ...
A study about the stabilization of anatase phase at high temperatures on sol-gel cerium and copper doped titania and titania-silica powders
(Elsevier Science BvAmsterdamHolanda, 2005)
