Supersonic waves may help electronics beat the heat

May 17, 2018

Researchers at the Department of Energy’s Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice—a discovery that may dramatically improv

Diamonds that deliver

February 24, 2017

It’s not enough to design new drugs. For drugs to be effective, they have to be delivered safely and intact to affected areas of the body. And drug delivery, much like drug design, is an immensely complex task.
