Atoms slip against one another, eventually sticking in various combinations. Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest ...

Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force ...

MADISON — To understand friction on a very small scale, a team of University of Wisconsin-Madison engineers had to think big. Friction is a force that affects any application where moving parts come ...

The upper figure shows the viscoelastic toy model proposed here, characterized by only six independent parameters. Surprisingly, this simple mechanical model produces complicated system dynamics, as ...
