Titanium Dioxide in Sunscreen

Titanium dioxide has been used in various industrial and cosmetic applications due to its unique elemental properties. This substance has a refractive index higher than most other compounds (n = 2.6142, in comparison to water at 20°C n = 1.33). This allows titanium dioxide to have an iridescent and bright quality. It has been used in the cosmetics industry for “whitening” and “thickening” in mu...

Graphite / Titanium Dioxide Composite

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

Investigation of resistive switching in anodized titanium dioxide thin films

In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications.  Increasing anodizing duration will increase nanotube lengths which itself c...
