Nanoparticles of titanium dioxide (TiO2) are commonly used in sunscreens as protection against ultraviolet radiation. Partly because the particles are so small, nanoscale TiO2 does not reflect visible ...

Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn't cool people off. However, a new formula, described in Nano Letters, protects against both UV ...

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.
