TiO2 sintetizado por el método de precursor polimerico (Pechini): estructura de la resina intermedia
Boletín de la Sociedad Española de Cerámica y Vidrio, 2011 In this work, the polymeric precursor method (Pechini method) was used to synthesize titanium dioxide. This process allowed a bigger control on the purity of the oxide and the crystalline phase present in the material.

Applied Sciences, 2023 Waste cooking oil, a known environmental pollutant, has been used as a precursor for the synthesis of onion-like nanocarbons (OLNCs) using flame pyrolysis. The OLNCs were added to TiO2 to form TiO2/OLNC nanocomposites through hydrothermal treatment.

Sulphuric Acid Digestion of Anatase Concentrate
Mining, 2023 The processing of anatase ores by sulphuric acid digestion is well known for its low titanium dissolution yields, which makes the process economically and technically unfeasible. Anatase is considered much less reactive than other forms of titanium such as ilmenite and rutile. Generally, to enhance its dissolution, thermal processes along with acid and/

Successful Growth of TiO2 Nanocrystals with {001} Facets for Solar Cells
Nanomaterials, 2023 The growth of nanocrystals (NCs) from metal oxide-based substrates with exposed high-energy facets is of particular importance for many important applications, such as solar cells as photoanodes due to the high reactivity of these facets.

The cytotoxic targets of anatase or rutile + anatase nanoparticles depend on the plant species
Biologia plantarum, 2017 The potential toxicity of nanoparticles (NPs) is under debate. Information about TiO2 NPs phytotoxicity is still limited partly due to the different TiO2 NP forms that may be found in the environment. The present work investigated the impact of different TiO2 NPs forms (rutile and anatase) on germination, growth, cell cycle profile, ploidy level, and ...

Acta Chimica Slovenica, 2017 The temperature dependence of the anatase-to-rutile phase transition of TiO2 powders and thin films was studied. In order to shift the phase transition to higher temperature, samples were doped with a different amount of phosphate ions and their ...

Water diffusion on TiO2 anatase surface [PDF]
AIP Conference Proceedings, 2015 Compatibility between biological molecules and inorganic materials, such as crystalline metal oxides, is strongly dependent on the selectivity properties and the adhesion processes at the interface between the two systems. Among the many different aspects that affect the adsorption processes of peptides or proteins onto inorganic surfaces, such as the ...

Refinement of the structure of anatase at several temperatures [PDF]
Zeitschrift für Kristallographie - Crystalline Materials, 1972 The crystal structure of anatase was refined at several temperatures between 25°C and 800°C using single-crystal x-ray diffraction data. The only structural parameter, the z coordinate of oxygen, changes regularly from 0.2081(2) at 25°C to 0.2076(3) at 800°C.
