A Theoretical Study on Friction of Macroscale Patterned Surfaces: Implications for Scaling Up Superlubricity. [PDF]
ACS Appl Mater Interfaces"Structural superlubricity", a state of frictionless sliding between crystalline surfaces, has been observed at the nanoscale and microscale. However, achieving it at the macroscale requires further investigation. Inspired by recent experimental studies, we theoretically examine the friction behavior of macroscale patterned surfaces composed of ...
