titanium | Infoplease
Titanium is a lustrous silver-white metal that exhibits allotropy; below about 880℃ it has a hexagonal crystalline structure, but above that temperature it changes to a cubic crystalline structure. The metal is strong and has low density; it is ductile when pure and malleable when heated. Its chemical properties resemble those of zirconium ...

Titanium dioxide (in the form of E171) is a ubiquitous excipient in tablets and capsules for oral use. In the coating of a tablet or in the shell of a capsule the material disperses visible and UV light so that the contents are protected from the effects of light, and the patient or caregiver cannot see the contents within. It facilitates elegant methods …
Titanium dioxide | Beauty Setup
Titanium dioxide is a common ingredient used in sunscreens to protect the skin from the harmful effects of the sun's UV radiation. It is an inorganic physical sunscreen that reflects UV radiation away from the skin's surface. This reflective action is achieved through the scattering of the UV light, which helps prevent it from penetrating the skin.

Fossil fuel is a non-renewable resource with limited reserves [1–3]. Over the past 140 years, we have consumed one trillion barrels of oil, and today, the world's demand for energy has exceeded 1000 barrels of oil, 100,000 cubic meters of natural gas, and 221 tons of coal per second [4]. It is clear that the consumption of fossil fuels is not sustainable in the long …
