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 ...

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 ...

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 ...

The study of friction and lubrication mechanisms at the nanoscale has increasingly focussed on graphene and its related two-dimensional materials, owing to their remarkable mechanical and tribological ...

By bridging the scale gap between nano and macroscale friction behavior, the team demonstrated that the stiction peak and its decrease are regulated by molecular processes inside contact junctions ...

The question is not how to eliminate friction. The question is how to manage it so it becomes traction and traction becomes forward motion.
