Superhydrophilic Hierarchical Anatase Coating on Sandblasted, Acid-Etched Titanium: In Vitro Apatite Formation and Osteoblast Responses and the Role of Polar Surface Free Energy [PDF]

Journal of Functional Biomaterials
Physicochemical modification of titanium implants aims to enhance early osseointegration by improving bioactivity. This study deposited and evaluated an anatase TiO2 film on clinically relevant sandblasted, acid-etched titanium (Ti-SLA) to enhance in ...

Hydrogen Donors in Anatase TiO2 [PDF]

physica status solidi (b), 2021
Two hydrogen‐related donors in anatase —interstitial hydrogen () and hydrogen substituting for oxygen ()—are addressed by means of ab initio density functional theory and vibrational mode spectroscopy. First‐principles calculations and infrared (IR) absorption measurements reveal that forms an OH bond lying in the basal plane of the crystal ...

Heterophase Polymorph of TiO₂ (Anatase, Rutile, Brookite, TiO₂ (B)) for Efficient Photocatalyst: Fabrication and Activity

Nanomaterials, 2023
TiO2 exists naturally in three crystalline forms: Anatase, rutile, brookite, and TiO2 (B). These polymorphs exhibit different properties and consequently different photocatalytic performances.
