Tribology applying to the intermediate mesoscopic area between the
microscopic world and the macroscopic world.
Tribology deals with friction and wear in the macroscopic world.
On the other hand,two major topics of micro-tribology research are the investigation of tribology
phenomena on an atomic or molecular scale, and the quantification of characteristics in friction or
wear. If the macro-characteristics generated on both surfaces undergoing relative motion are traced
to where they originate, the minimum unit of the atomic or molecule cluster causing those
characteristics is reached. Observation on a finer scale reaches a boundary at which these
characteristics disappear. Mesotribology pursues new developments on the micro-macro boundary by
bringing together atoms on a subnanometer scale to create a mesoscopic scale and investigating the
tribological phenomena on this scale.
