Testing trace-element distribution and the zr-based thermometry of accessory rutile from chromitite
(2021-07-01)
Trace element distribution and Zr-in-rutile temperature have been investigated in accessory rutile from stratiform (UG2, Merensky Reef, Jacurici), podiform (Loma Peguera), and metamorphic chromitites in cratonic shields ...
Favoring the Reactivity of TiO 2 Films with Ideal Arrangement of Anatase and Rutile Crystallites
(2019-04-22)
It is shown that there are deposition conditions in reactive sputtering of TiO 2 in which the anatase and rutile crystals can coherently arrange in a convenient way that predominantly exposes the anatase facets, a configuration ...
Enhancement of rutile phase formation in TiO2 films deposited on stainless steel substrates with a vacuum arc
(Elsevier Science Sa, 2017-07)
The rutile phase of TiO2 has raised a wide interest for biomaterial applications. Since rutile is generally synthesized at high temperatures, a deposition process based on a cathodic arc discharge has been investigated in ...
Study of rutile-supported anatase nanostructured films as photocatalysts for the degradation of water contaminants
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2015-03-30)
This dissertation studies the application of rutile substrate as an alternative support for anatase films, specifically, on the growth and properties of anatase films. The films were utilized as catalysts for the ...
Covalent Anchoring and Interfacial Reactions of Adsorbed Porphyrins on Rutile TiO2(110)
(American Chemical Society, 2018-03)
Adsorption of 5-monocarboxyphenyl-10,15,20-triphenylporphyrin (MCTPP) to rutile TiO2(110) at room temperature produces molecules on the surface covalently anchored through the carboxylate group, coadsorbed with hydroxyl ...
Anisotropic growth of oxide nanocrystals: Insights into the rutile TiO2 phase
(Amer Chemical Soc, 2007-04-26)
In this work, we report the synthesis of titanium oxide nanocrystals, especially the rutile TiO2 phase with nanorod morphology, by a method based on peroxotitanium complex decomposition. The results indicate that the ...

The cedrolina chromitite, Goiás State, Brazil: A metamorphic puzzle
(2016-09-01)
The Cedrolina chromitite body (Goiás-Brazil) is concordantly emplaced within talc-chlorite schists that correspond to the poly-metamorphic product of ultramafic rocks inserted in the Pilar de Goiás Greenstone Belt (Central ...
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 ...
