Advanced Science, Volume 11, Issue 19, May 22, 2024.By sphere‐triggered strain engineering, the graphene moiré structure (GMS)‐assembled surfaces are formed. The superlubricity between GMS‐assembled and DLC25 surfaces in wide ranges of normal load (7–11 N), sliding velocity (0.5–27 cm s−1), contact area (0.4×104–3.7×104 µm2), and contact pressure (0.19–1.82 GPa) can be achieved based on assembly face ...

Graphene Nanoflakes: Superlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes (Adv. Sci. 3/2018) [PDF]
Advanced science, 2018 Superlubricity between graphite and silica is achieved under ambient conditions, induced by the formation of multiple transferred graphene nanoflakes (GNFs) on a silica surface. As reported by Jinjin Li and co‐workers in article number 1700616, the friction coefficient could be reduced to 0.0003 at a maximal local contact pressure of 700 MPa because of

Casimir‐Lifshitz Optical Resonators: A New Platform for Exploring Physics at the Nanoscale
Advanced Physics Research, Volume 3, Issue 2, February 2024.Levitation, or trapping, of a flat mirror at a certain distance above another flat reflecting surface, as a result of the compensation of attractive gravitational forces by a quantum fluctuation induced repulsive force, leads to the formation of Casimir‐Lifshitz optical resonators, which have opened the possibility to explore a wide range of physical ...
