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

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely ...

In manufacturing, not all losses are loud. Some happen quietly, every second, in the background. Friction is one of them. Each time two parts move, whether turning, sliding or rolling, energy is lost.
