Titanium dioxide (TiO 2) nanoparticles have a high refractive index (n = 2.4), making them ideal for various applications, including medicines, coatings, inks, plastics, food, cosmetics, and textiles.

Heterocyclic compounds are organic molecules with a ring structure comprising at least two or more elements. In most cases, these rings are composed of carbon atoms along with one or more other ...

Researchers at the Ritsumeikan University in Japan have fabricated a heterojunction solar cell that utilizes a window layer made of titanium oxide (TiO2) and an absorber based on selenium (Se). The ...

Measuring the band gap of materials is vital in the nanomaterial, semiconductor, and solar industries. This article illustrates how the band gap of a material can be established from its UV absorption ...

Most chemists would describe titanium dioxide as an ionic compound composed of Ti 4+ and two O 2–. Not so, suggests a theoretical analysis: TiO 2 is better described with the charge states Ti 3+ and O ...

Titanium dioxide is crucial in 91,000 drug products for color and stability, despite safety concerns from the European Food Safety Authority. The European Medicines Agency found alternatives to TiO2 ...

Cambridge University spin-out Impossible Materials has developed a cellulose-based, white pigment to replace titanium dioxide in food applications. FoodNavigator catches up with CEO Lukas Schertel to ...
