Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that arises without any mechanical contact, driven purely by collective magnetic ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

The less work required to translate an object, the better. Avoiding sliding friction — a major sinkhole of applied force for motion — is accomplished through rolling. A: Ironically, with increased ...
