Observing at the extremes— nanomechanical materials testing at over 2,000°C

By Lisa McDonald / March 3, 2020

Performing microscale experiments at ultrahigh temperatures is difficult because the high heat can destroy the testing mechanisms. Researchers demonstrated a new method, which combines targeted laser heating and transmission electron microscopy, that may overcome this problem.

Cracking the case of ceramic “softening”: Size-induced grain boundary energy affects hardness of ceramics

By Lisa McDonald / December 20, 2019

When grain sizes in ceramics become critically small, ceramics can appear to soften. Researchers led by the University of California, Davis, show this false impression is due to an extensive network of nanocracks caused by increased grain boundary energy.

Two theories, one goal—new formula also describes heat flow in both crystals and glass

By Lisa McDonald / August 30, 2019

In May, a formula was published that could describe thermal transport in both crystals and glass. Now, a new formula by researchers in Italy and the United States based on a different mathematical framework can also model such thermal transport.
