Friction is the enemy of all things mechanical, and without regular maintenance, machinery service life becomes severely reduced until, ultimately, the machines cease to function. Anyone who owns a ...

For the first time, physicists in China have virtually eliminated the friction felt between two surfaces at scales visible to the naked eye. In demonstrating "structural superlubricity," the team, led ...

When two solid surfaces come into contact with each other, friction acts to prevent their relative motion, but the ability to reduce this friction to nearly zero is called structural superlubricity.

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 ...
