Although often viewed as an undesirable phenomenon due to its wearing effects on materials, too little friction can be a disadvantage.

According to a December 15 news release from the University of Basel, an international team of scientists has observed a considerable energy loss brought about by frictional effects around charge density waves, and may have practical applications to controlling nanoscale friction.
The research results appear online in Nature Materials, in an article entitled, “Giant frictional dissipation peaks and charge-density-wave slips at the NbSe2 surface.”
