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 ...

Researchers have demonstrated how to entirely suppress static friction between two surfaces. This means that even a minuscule force suffices to set objects in motion. Especially in micromechanical ...

Physicists should “think big” when it comes to calculating the effects of friction on tiny nanomachines, according to researchers in the US, who say that they have strong evidence against the widely ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Scientists have recently created new bio-inspired film-terminated structures with unique friction characteristics that could have positive industrial implications for, among other things, tires. The ...

Elisa Riedo, a Professor of Chemical and Biomolecular Engineering, and her colleagues have uncovered a fundamental friction law that is helping to improve the knowledge of how energy is lost during ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...
