Pulsed Power System Cooling

DSIAC received a request for information on methods to better cool a high-energy, pulsed power system.  DSIAC solicited assistance from subject matter experts (SMEs) at the Texas Research Institute Austin (TRI Austin), who held two teleconferences with the requestors to better…

NREL-Led Research Effort Creates New Alloys, Phase Diagram

A multi-institutional team led by the U.S. Department of Energy”s National Renewable Energy Laboratory (NREL) discovered a way to create new alloys that could form the basis of next-generation semiconductors. Semiconductor alloys already exist-often made from a combination of materials with similar atomic arrangements-but until now researchers believed it was unrealistic to make alloys of

Researchers “Iron out” Graphene’s Wrinkles

New technique produces highly conductive graphene wafers. From an electron’s point of view, graphene must be a hair-raising thrill ride. For years, scientists have observed that electrons can blitz through graphene at velocities approaching the speed of light, far faster than they can travel through silicon and other semiconducting materials. Graphene, therefore, has been touted

Hidden Properties of Solids

Physicists open the door to the first direct measurement of Berry curvature in solid matter. Berry curvature may not be the most well-known scientific concept, but to many physicists, its direct measurement is something akin to a holy grail. A powerful unifying principle in several branches of classical and quantum physics, Berry curvature is a
