Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, ...

A team of researchers has developed a printing technique capable of forming a periodic nano/microstructure on the surface of a polydimethylsiloxane (PDMS) slab and easily transferring it onto the ...

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 ...
