On November 26, 2018, researchers from Oak Ridge National Laboratory received the Joule Award from Barbara Hoffheins of the National Nuclear Security Administration (NNSA) Office of International Nuclear Safeguards.
Concentrated transition metal alloys with the formula NiCoCrx, with x≈1, and a simple cubic crystal structure, display transport, magnetic and thermodynamic signatures exhibited by more structurally complex compounds near a quantum critical point (QCP).
Helium implantation allows for continuous control of optical band gaps in semiconducting films through the resultant strain — an impossibility with traditional strain engineering.

Multiferroic materials are important because their electrical and magnetic properties are coupled. Because BiFeO3 magnetically orders below 640 K, it is one of two known room-temperature multiferroic materials.
Scientific Achievement The effects of porous media on precipitation reactions are shown to be important, but poorly understood. Significance and Impact Geochemical reactions within rocks and soils occur in pores.
Theoretical calculations, based on newly obtained experimental geometries in strained BiFeO3 thin films, predict an almost barrierless transition between co-existing phases.
