Innovative LEDs Clean Up Water in Remote Areas
For the first time, researchers have created light-emitting diodes (LEDs) on lightweight flexible metal foil. Engineers at The Ohio State University are developing the foil based LEDs for portable ultraviolet (UV) lights that soldiers and others can use to purify drinking water and sterilize medical equipment. In the journal Applied Physics Letters, the researchers describe…
