Electric fields induce oscillations in tiny particles
June 24, 2021
CBES researchers led by Kyle Bishop and Monica Olvera de la Cruz have demonstrated the use of DC electric fields to drive back-and-forth rotation of micro-particles in electric boundary layers. These particle oscillators could be useful as clocks that coordinate the organization of active matter and even, perhaps, orchestrate the functions of micron-scale robots.
“Tiny particle oscillators could enable new types of active matter that combine the swarming behaviors of self-propelled colloids and the synchronizing behaviors of coupled oscillators,” Bishop said. “We expect interactions among the particles to depend on their respective positions and phases, thus enabling richer collective behaviors—behaviors that can be designed and exploited for applications in swarm robotics.”

Balazs elected to National Academy of Sciences
May 17, 2021
CBES senior investigator Anna Balazs has been elected to the National Academy of Sciences in recognition of distinguished and continuing achievements in original research. Balazs, Distinguished Professor of Chemical and Petroleum Engineering at the University of Pittsburgh, is one of 120 newly elected members to the prestigious academy — including a one-year record of 59 women.
“Throughout her career, Anna has advanced the field of materials and computational modeling, and we are so proud that the National Academy of Sciences has bestowed her with this honor,” said James R. Martin II, U.S. Steel Dean of Engineering at Pittsburgh. “Her research has built the foundation for future materials and their use in ways that even only a decade ago were science fiction.”
