We examined a minimal model for an active colloidal fluid in the form of self-propelled Brownian hard spheres that interact purely through excluded volume. Using simulations and analytic modeling, we ...

This work shows a way to generate oscillators, which could lead to the emergence of cooperative phenomena in fluids. Monica Olvera de la CruzLawyer Taylor Professor of Materials Science and ...

Active matter is commonly understood as particles that can be self-propelled to acheive complex motions and are found in nature and the man-made worlds. Natural systems such as fish, birds, ants and ...

Researchers report that they 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 ...

New York, NY--June 23, 2021--A challenging frontier in science and engineering is controlling matter outside of thermodynamic equilibrium to build material systems with capabilities that rival those ...
