New high-volume joining process expands use of aluminum in autos

Researchers have demonstrated a new process for the expanded use of lightweight aluminum in cars and trucks at the speed, scale, quality and consistency required by the auto industry. The process reduces production time and ...

Semiconductor works better when hitched to graphene

Graphene – a one-atom-thick sheet of carbon with highly desirable electrical properties, flexibility and strength – shows great promise for future electronics, advanced solar cells, protective coatings and other uses, ...

Researchers tune friction in ionic solids at the nanoscale

Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the Department of Energy's Oak Ridge National ...

NREL demonstrates 45.7% efficiency for concentrator solar cell

The Energy Department's National Renewable Energy Laboratory has announced the demonstration of a 45.7 percent conversion efficiency for a four-junction solar cell at 234 suns concentration. This achievement represents one ...

Reviving algae from the (almost) dead

Tucked away in darkness and almost dead, algae can emerge from a frigid and foggy environment to live again—and perhaps even become the seeds for a new beginning that can provide biofuel for a clean energy future.
