Superlubricity is a state of superlow friction (friction coefficient is less than or equal to 0.001~0.01), which is two orders of magnitude lower than conventional lubrication. Our group focuses on both experimental and theoretical studies on superlubricity of nanomaterials (graphene, MoS2, etc), which is of potential value for lubrication in micro-/nano-electromechanical systems.

Recent interests:

1. Mechanism and realization of superlubricity of solids

2. Frictional behaviors of nanomaterials

3. Micro-/nano-manufacturing
