Superlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes
Advanced Science, 2018 2D or 3D layered materials, such as graphene, graphite, and molybdenum disulfide, usually exhibit superlubricity properties when sliding occurs between the incommensurate interface lattices.

Water molecules on the liquid superlubricity interfaces achieved by phosphoric acid solution
Biosurface and Biotribology, 2018 The superlubricity mechanism of phospholipid molecules on biological surfaces and interfaces has been receiving much attention. Since the superlubricity can be achieved with a phosphoric acid aqueous solution, the interaction of the phosphate group with ...

Superlubricity, a state where friction between two contact surfaces is nearly zero, has a great potential to revolutionize various mechanical systems by significantly reducing energy dissipation and enhancing efficiency. It can be realized either by structural incommensurate contact between crystalline surfaces or by creating highly passive interfaces ...

Electrostatic in-plane structural superlubric actuator [PDF]
Nature CommunicationsMicro actuators are widely used in NEMS/MEMS for control and sensing. However, most are designed with suspended beams anchored at fixed points, causing two main issues: restricted actuated stroke and movement modes, and reduced lifespan due to fatigue ...

Strain‐Driven Superlubricity of Graphene/Graphene in Commensurate Contact
Advanced Materials Interfaces, 2023 The occurrence of structural superlubricity (SSL) requires that two sliding surfaces be in incommensurate contact. However, the incommensurate contact between two sliding surfaces is fundamentally an instable state whose maintenance over time is ...

Microscale Contact Electrification with Unprecedented High Intrinsic Charge Density. [PDF]
SmallWith the atomically flat contact interface by a microscale graphite slider and polytetrafluoroethylene, microscale contact electrification with high contact efficiency is achieved. The developed microscale triboelectric nanogenerator exhibits a record‐high intrinsic triboelectric charge density of 2.6 mC m−2, which is attributed to the greatly enhanced
