Graphite foam cools hi-intensity LEDs
August 31, 2010
Light-emitting-diodes (LEDs), once quoted to have 100,000-hour lifetimes, are still working today in some front-panel indicators after 30 years of service. But the advent of high-intensity LEDs for solid-state lighting sacrifices longevity by operating at temperatures too high for lifetimes much longer ...

China researchers claim faster MRAM
August 30, 2010
MRAM speed can be boosted and power consumption cut by using a new electrical switching technique that requires much less energy to write bits, according to Chinese researchers. The basic idea is to switch magnetic domains "halfway" rather than to completely reverse their magnetic orientation, which ...
