Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become ...
(Phys.org)—Researchers have designed a new type of microgear that spins when micromotors become lodged into the corners of the gear's teeth. The micromotors use the surrounding hydrogen peroxide solution as fuel to propel ...
University of Colorado Boulder researchers have discovered that minuscule, self-propelled particles called "nanoswimmers" can escape from mazes as much as 20 times faster than other passive particles, paving the way for their ...

In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired ...
Traveling waves are commonly observed in biological and synthetic systems, and recent discoveries have shown how silver colloids form traveling motion waves in hydrogen peroxide under UV light. In a new report now published ...
Researchers from The Research Center for Advanced Science and Technology and The Institute of Industrial Science at The University of Tokyo used a new computer simulation to model the electrostatic self-organization of zwitterionic ...
