Diode lasers may vie with LEDs for lighting supremacy

October 26, 2011 7:15 am | News | Comments

Light-emitting diodes (LEDs) are widely accepted as a more efficient and reliable option than tungsten incandescent bulbs. But recent research at Sandia National Laboratories shows that humans are as comfortable with white light generated by diode lasers, which are more efficient than LEDs at higher amperages.

Simulating turbulent combustion speeds design

September 22, 2011 5:04 am | News | Comments

Multiscale complexity is common across all combustion applications—internal combustion engines, rockets, and industrial boilers—and can range from tens of meters to billionths of meters. New techniques being employed at supercomputers covers this huge scale range using fewer computer hours, and could benefit efficiency levels in the combustion industry.
