Friction normally needs two surfaces rubbing together. Physicists just proved light can do the job all by itself.

A research group led by Dr. Masahiro Goto and Dr. Michiko Sasaki created an unprecedented, highly efficient method for developing friction materials with a desired frictional property. The method is ...

No less than one-third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can ...

Scientists have observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. This may have practical significance in the control of nanoscale friction. In ...

A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction. An innovative method of ...

Rainfall soothes the atmosphere, atmospheric scientists have found. They calculate that a substantial portion of the energy that drives wind and air circulation in the atmosphere is dissipated as ...
