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 ...

When load increases steadily, so does friction, but in the realm of magnetization dynamics, things aren’t so simple.

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 ...

Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained cooling effect without external input. (Nanowerk News) How can a horde of ...

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.

Measuring 63.5 (H) x 88.9 (W) x 266.7 (L) mm, the Dover MAB-100 linear motor stage uses an air-bearing guideway to deliver friction-free straight-line motion up to 100 mm in length. The device ...

I'll be honest—friction is pretty complicated. Imagine that I have a block of wood sliding on a table. In some way, the atoms on the surface of the wood block are interacting with the surface atoms on ...
