Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

Hydrogen, a clean energy source, requires a highly reliable and safe storage system, which is currently lacking. Layered ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to waste. Instead of relying only on the most energetic visible wavelengths, ...

The importance of solar power as a renewable energy resource is increasing. Sunlight contains high-energy UV light with a wavelength shorter than 400 nm, which can be broadly used, for example, for ...
