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

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 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

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 ...

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 ...

Evonik’s Resource Efficiency Segment has unveiled its new Friction and Motion Competence Centre in Darmstadt, Germany. The Centre acts as a technology platform focusing on development of mid- and long ...
