New leds may offer better way to clean water in remote areas   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 how they designed the LEDs to shine in the high-energy “deep” end of the UV spectrum. The university will license the technology to industry for further development.   https://www.sciencedaily.com/releases/2016/11/161115155318.htm
