Simple microparticles can beat rhythmically together, generating an oscillating electrical current that could be used to power microrobotic devices.

Prizes in the materials science competition also went to a waste-monitoring device and a nanofiber-based yarn.

New tools can accommodate samples from small pieces up to 200 mm wafers.

The technique could be used to fabricate computer chips that won’t get too hot while operating, or materials that can convert waste heat to energy.

Cobalt-based catalysts could be used to turn mixed plastic waste into fuel, new plastics, and other products.

The ceramic-based material could be used for highly efficient actuators for aircraft or other uses, with minimal moving parts.

Graduate students create on-campus assembly factory for fiber extrusion devices.

Awards support high-risk, high-impact research from early-career investigators.
