Friction almost vanishes in microscale graphite

from PhysOrg

Scientists first observed superlubricity in graphite in 2004, and so far all experimental evidence of superlubricity has been obtained on the nanoscale and under vacuum conditions. But in a new study, scientists have demonstrated that superlubricity in graphite can occur over microscale areas and under ambient conditions, which could open the way toward practical applications in micromechanical systems. more
