Light reshapes metal-organic framework to harvest airborne water

Phys · · 633 words · By Richard C Lewis

Researchers at the University of Iowa have developed a metal-organic framework that uses ultraviolet light to create cavities capable of capturing and storing water from the air. The study, published in the Journal of the American Chemical Society, suggests the technology could eventually assist in providing drinking water to water-stressed regions.
