3D Printing/Additive Manufacturing

UNIVERSITY PARK, Pa. — A recently installed 3D ceramics printer offers Penn State materials researchers advanced capabilities to easily produce high-resolution ceramic parts and other innovative ceramics for cutting-edge materials research at a lower cost than sourcing them.

Acoustic waves may be able to control how particles sort themselves. While researchers have been able to separate particles based on their shape — for example, bacteria from other cells — for years, the ability to control their movement has remained a largely unsolved problem, until now. Using ultrasound technology and a nozzle, Penn State researchers have separated, controlled and ejected different particles based on their shape and various properties.

UNIVERSITY PARK, Pa. — Reconfigurable antennas — those that can tune properties like frequency or radiation beams in real time, from afar — are integral to future communication network systems, like 6G. But many current reconfigurable antenna designs can fall short: they malfunction in high or low temperatures, have power limitations or require regular servicing.
