Chemical changes of titanium and titanium dioxide under electron bombardment
(Universidade Federal de São Carlos, 2007-12)
The electron induced effect on the first stages of the titanium (Ti0) oxidation and titanium dioxide (Ti4+) chemical reduction processes has been studied by means of Auger electron spectrescopy. Using factor analysis we ...
REDUCED TITANIUM-DIOXIDE AS SUPPORT FOR ZIEGLER-NATTA CATALYSTS
(John Wiley & Sons IncNew York, 1994)
Experimental and theoretical approach of nanocrystalline TiO2 with antifungal activity
Using a solvothermal method for this research we synthesized nanocrystalline titanium dioxide (nc-TiO2) anatase particles with a mean diameter of 5.4 nm and evaluated their potential antifungal effect against planktonic ...
Effect of the iron doping on the thermal decomposition of the polymeric precursor for the titanium dioxide powder synthesis
The Polymeric Precursor Method has proved suitable for synthesizing reactive powders using low temperatures of calcination, especially when compared with conventional methods. However, during the thermal decomposition of ...
Effect of iron and vanadium on the phase transition of titanium dioxide obtained by polymeric precursor method
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 ...
Surface Physicochemical and Structural Analysis of Functionalized Titanium Dioxide Films
Titanium and its alloys are recognized as acceptable materials for many applications. The properties of titanium dioxide (TiO2) thin films are directly related to the structural characteristics of the material, which can ...
Shifting to the red the absorption edge in TiO2 films: a photoacoustic study
(SUPERFICIES Y VACIO, 2013-01-16)
Experimental Method to Evaluate the Optical Properties of Aqueous Titanium Dioxide Suspensions
(American Chemical Society, 2005-12)
The evaluation of the radiation field inside a slurry reactor constitutes a central step in the study of photocatalytic reactions. This task can be achieved by solving the radiative transfer equation (RTE) for the system ...
Cosmetic Nanomaterials in Wastewater: Titanium Dioxide and Fullerenes
(American Society of Civil Engineers, 2016-01)
The rapid growth in the cosmetic industry across the world is mainly due to the application of nanoingredients in cosmetics to enhance their properties and invention of new nanomolecules. Also, the weaker regulations on ...
Identification and photocatalytic destruction of malodorous compounds in sewage
(Selper Ltd, Publications DivLondonInglaterra, 2008)
