“Better” Copper Means Higher-Efficiency Electric Motors

Researchers at PNNL have increased the conductivity of composite copper wire by 5%. That small percentage can make a big difference in motor efficiency. The laboratory teamed with General Motors to test out the souped-up copper wire for use in vehicle motor components, as part of a cost-shared research project.

All together now: Experiments with twisted 2D materials catch electrons behaving collectively

A team led by the University of Washington reports that carefully constructed stacks of graphene — a 2D form of carbon — can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.

Next-Generation Electron Source Hits the Bullseye for Materials Studies

Researchers have designed and demonstrated a new bullseye lens for very bright, very fast electron sources. The lens combines atomically flat surfaces with concentric grooves that direct the interactions of the surface electrons to form an intense electron beam in the center of the bullseye. The lens can generate pulses lasting less than 10 femtoseconds.
