Anatase Nanosurface Regulates MicroRNAs

Journal of Craniofacial Surgery, 2008
Titanium is the criterion standard among materials used for prosthetic devices because of its good mechanical and chemical properties. When exposed to oxygen, titanium becomes an oxide that is biocompatible and able to induce osseointegration. There are 3 allotropic forms of titanium dioxide: brookite, rutile, and anatase.

Pure anatase and rutile + anatase nanoparticles differently affect wheat seedlings

Chemosphere, 2016
TiO2-nanoparticles (TiO2-NPs) are increasingly released to the environment. The present work investigates the cytotoxicity, genotoxicity and uptake of TiO2-NPs in Triticum aestivum. Wheat seeds were exposed to 5-150 mg L(-1) of anatase (ana) or rutile + anatase (rut + ana) TiO2-NPs for 5 d.

Steps on anatase TiO2(101)

Nature Materials, 2006
Surface defects strongly influence the surface chemistry of metal oxides, and a detailed picture of defect structures may help to understand reactivity and overall materials performance in many applications. We report first-principles calculations of step edges, the most common intrinsic defects on surfaces (and probably the predominant ones on ...

DFT modeling of anatase nanotubes

Journal of Materials Chemistry, 2011
TiO2 nanotubes constructed from anatase TiO2 layers were investigated with DFT methods employing the periodic CRYSTAL code. Films of thickness from one to three TiO2 layers (1-3 ml) have been considered. The dependence of strain energies, structural and electron properties on the tube diameter was investigated in the 10-70 A range. Relative stabilities

Photoluminescence study on defects in pristine anatase and anatase-based composites

Physica B: Condensed Matter, 2003
Under 325 nm laser light irradiation at room temperature in oxygen gas, the photoluminescence (PL) intensity of pristine anatase TiO 2 decreases considerably and then it recovers reversibly with the same laser light irradiation at room temperature in vacuum. This result gives important information on the oxygen defects at anatase particle surfaces and
