Cracking carbon bonds is a notoriously difficult problem, but it may hold the key to generating greener, more sustainable chemicals. A Chinese research team achieved the first visible-light-promoted ...

A study participant puts in a contact lens. Researchers developed lenses with nanoparticles that convert infrared wavelengths into visible light that humans can perceive. Yuqian Ma, Yunuo Chen, Hang ...

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 ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...
