    • An adhesion-dominated rolling Friction regime unique to micro-scale ball bearings 

      Hanrahan, Brendan M.; Misra, Saswat; Beyaz, Mustafa İlker; Feldman, Jeremy H.; Waits, Christopher M.; Ghodssi, Reza (Tribology Letters, 2014)
      We demonstrate that micro-scale rolling bearings exhibit friction and wear properties markedly different from their macro-scale counterparts. A microfabricated testing platform uses variable rolling element diameters or ...
