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 ...

Frictional experiment: artist’s impression of the metainterface between a rigid piece of glass (top) and a metasurface (bottom). The textured regions are where the glass and metasurface are in contact ...

Introduction Sometimes friction can be annoying. It can make it difficult to push heavy things like furniture and it can even give you a nasty scrape if you fall. But friction is actually very ...

Friction is an important fact of life, robbing efficiency from anything where two surfaces interact with each other, such as engines and wheels. Lubrication can reduce the amount of friction, but it's ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.
