Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...

When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is ...

Add Yahoo as a preferred source to see more of our stories on Google. Friction, though familiar in everyday life, remains a complex phenomenon—especially at the microscopic level. Scientists long ...

How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine ...

There is a thin layer immediately above the Earth's surface known as the surface boundary layer (or simply the surface layer). This layer is only a part of the planetary boundary layer and represents ...

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

New method simulates electronic friction effects on quantum motion, explaining hydrogen diffusion on copper with relevance to catalysis and energy storage. (Nanowerk News) George Trenins and Mariana ...
