DOE: Nanostructures Half a DNA Strand-Wide Show Promise for Efficient LEDs

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the “green gap,” a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy’s National Energy Research Scientific Computing Center (NERSC) have shown.

GE Lights Up Indiana Communities

The Indiana Municipal Power Agency (IMPA), a wholesale power supplier, was awarded a recent U.S. Department of Energy grant to fund the retrofitting of outdoor street lights in member communities with light emitting plasma and LED street lighting fixtures. Through a competitive process, the communities collectively selected the GE’s energy-efficient Evolve™ LED Roadway Cobrahead fixtures to replace mercury vapor, metal halide and high-pressure sodium lamps, some of which had been in use for more than half a century.

Cree Receives $2.3M Grant for LED Lighting Progress

Cree has received a matching $2.3 million U.S. Department of Energy grant to advance its research and development of light-emitting diode, or LED, lighting products. The agency said the $10.1 million in competitive, matching grants to five companies are for two-year projects that "will focus on achieving significant cost reductions while maintaining quality by improving manufacturing equipment, processes, or monitoring techniques." Greg Merritt, vice president for marketing with Durham, N.C.-based Cree, said Wednesday the company has been working with the DOE...
