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 ...
Growth of TiO2 nanotubes by anodization of Ti-7.5Mo in NH 4F solutions
(2013-04-01)
Titanium and its alloys are widely used as biomaterials due to their mechanical, chemical and biological properties. To enhance the biocompatibility of titanium alloys, various surface treatments have been proposed. In ...
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 ...
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 ...
Investigation of photoinduced electrical properties in the heterojunction TiO2/SnO2
(Trans Tech Publications Ltd, 2014-01-01)
TiO2/SnO2 thin films heterostructures were grown by the sol-gel dip-coating technique. It was found that the crystalline structure of TiO2 depends on the annealing temperature and the substrate type. TiO2 films deposited ...
Organic additives used as binders and pore-forming elements of TIO2 ceramics
(2017-01-01)
When starches/proteins are added to the ceramic matrix, they originate pores whose morphology and sizes are varied. However, ceramic final properties are influenced by the interaction kinetics amongst particulate materials. ...
Photocatalytic and photoelectrochemical treatment effects on the killing of escherichia coli cells
(2005-12-01)
In this study, we report the efficiency of photocatalytic and photoelectrochemical treatment using titanium dioxide as semiconductor and its applications in water disinfection. It was compared the efficiency of the two ...
Anelastic spectroscopy in TiO2
(2005-12-01)
Titanium dioxide (rutile) has a lot of interesting and useful features and hence is widely utilized for application. It has been used as white pigment, photocatalyst, biocompatible material and semiconductor material used ...
Effect of scandium on the structural and photocatalytic properties of titanium dioxide thin films
(2008-01-01)
Pure and scandium doped-TiO2 thin films were prepared by the sol-gel process and coated by dip coating. The effects of scandium on the phase formation, optical properties and photoactivity of the TiO2 thin films were ...
Microstructure of ceramics TiO2 obtained by protein consolidation
(2012-11-26)
Porous ceramics can be produced by adding starch (corn, potato) and protein (animal or vegetable) to raw material as pore forming element. In this study, titanium dioxide ceramics were formed by vegetable protein consolidation. ...
