New Turbulent Transport Modeling Shows Multiscale Fluctuations in Heated Plasma

Researchers at the DIII-D National Fusion Facility used a “reduced physics” fluid model of plasma turbulence to explain unexpected properties of the density profile inside a tokamak experiment. Modeling plasma’s turbulent behavior could help...

Three’s Company: New Alloy Sets Magnetism Benchmark

Spintronics leverages electron spins to enhance solid-state devices by prolonging battery life. Spintronic developments, however, are increasingly running up against the Slater-Pauling limit, the maximum for how tightly a material can pack its...

Sequential Model Chips Away at Mysteries of Aircraft Ice

Ice accumulation on aircraft wings is a common contributing factor to airplane accidents. Most existing models focus on either ice that freezes as a thin film on the airfoil, or immediately after it impacts the wing. Researchers have announced a new...

Advances Open New Frequency Range for Wireless Communications

The “internet of things,” which make everything from your toaster to your front door accessible online, has driven an explosion in data traffic and taken up huge amounts of bandwidth. However, a new range of frequencies in the terahertz region...
