This magnified image from a transmission electron microscope reveals details of the unexpected nanosheet structure of the nickel-molybdenum-nitride catalyst, seen here as dark, straight lines.

Hydrogen gas offers one of the most promising sustainable energy alternatives to limited fossil fuels. But traditional methods of producing pure hydrogen face significant challenges in unlocking its full potential, either by releasing harmful carbon dioxide into the atmosphere or requiring rare and expensive chemical elements such as platinum…

Philips LED light wins U.S. Department of Energy’s $10m ‘Lighting Prize’

Philips-AmbientLED-12-watt-LED-Lightbulb-lprize-photo-0001

It looks like the Philips AmbientLED has won the U.S. Department of Energy’s Lighting Prize (modeled on the original X-Prize). The goal was to help “transform lighting technology” by making it more efficient. To win, the Philips LED had to go through some pretty sophisticated tests (see the video below) to make sure the light quality was good and that it was durable…  (video after jump)
