“Heftier” Atoms Reduce Friction at the Nanoscale, Study Led By Penn Researcher Reveals

PHILADELPHIA - A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface.  Heavier atoms vibrate at a lower frequency, reducing energy lost during sliding.

The study appears in the November issue of the journal Science.
