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 ...

500 years after the first studies on friction, the concepts of superlubricity, wearless sliding and friction control are being realized in laboratories and have become predictable by adequate ...

In general, friction between two macroscale surfaces is proportional to normal force. However, the frictional characteristics of nanoscale surfaces cannot be fully described by the framework of ...
