Scientists turn single molecule clockwise or counterclockwise on demand

Argonne scientists report they can precisely rotate a single molecule on demand. The key ingredient is a single atom of europium, a rare earth element. It rests at the center of a complex of other atoms and gives the molecule many practical applications.

LED Material Shines Under Strain

A team led by researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has demonstrated an approach for achieving LEDs with near 100% light-emission efficiency at all brightness levels.
