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

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

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

Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving ...

A recent article published in Advanced Functional Materials investigated the friction behavior of surfaces coated with ...

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.
