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 ...

A model system has been presented by researchers that allows the investigation of atomic-scale friction effects and friction dynamics that are similar to those taking place, for instance, in proteins, ...

When it comes to understanding friction on the nanoscale, no comprehensive model exists. Scientists have only a general understanding of friction's atomic-level behavior ... but that's changing. Plus: ...
