Nanomaterials in Superlubricity
Advanced Functional Materials, 2019AbstractThe vanishing friction, known as superlubricity, is potentially a significant performance indicator in the development of nanostructured materials and has become increasingly important for realizing energy saving and extending the life of mechanical components.

Superlubricity of molybdenum disulphide
Physical Review B, 1993We have studied the atomistic origins of the ultralow friction coefficient of a molybdenum disulphide (${\mathrm{MoS}}_{2}$) coating in ultrahigh vacuum conditions. A friction coefficient in the ${10}^{\mathrm{\ensuremath{-}}3}$ range is associated with friction-induced orientation of ``easy shear'' basal planes of the ${\mathrm{MoS}}_{2}$ crystal ...

Advancements in superlubricity
Science China Technological Sciences, 2013Superlubricity is a new area in tribology, in which the slide friction coefficient is about 1/1000 to 1/100 of the general ones. Since the concept of superlubricity was proposed, it has attracted more and more attentions from researchers in fields of tribology, physics, chemistry, materials, etc.

Superlubricity, a lubricating state in which the coefficient of friction (COF) is smaller than 0.01, has been achieved at the macroscale in a variety of aqueous solutions and oils, as well as two-dimensional (2D) and carbon materials; nevertheless, it has been rarely realized with polymer composites.

Robust superlubricity by strain engineering
Nanoscale, 2019We demonstrate that robust superlubricity can be achieved via both biaxial and uniaxial tensile strains in a substrate using molecular dynamics simulation. Above a critical strain, the friction is no longer dependent on the relative orientation between the surfaces mainly due to the complete lattice mismatch.

Collective superlubricity of graphene flakes
Journal of Physics: Condensed Matter, 2016We investigate solid lubrication of graphene and graphene flakes using atomistic molecular-dynamics simulations. We find that graphene flakes yield lower friction than graphene as a result of a collective mechanism that emerges from the independent behaviour of the flakes.

Superlubricity means non-sticky and frictionless when two bodies are set contacting motion. Although this occurrence has been extensively investigated since 1859 when Faraday firstly proposed a quasiliquid skin on ice, the mechanism behind the superlubricity remains debating.

Superlubricity between MoS2 Monolayers
Advanced Materials, 2017The ultralow friction between atomic layers of hexagonal MoS2, an important solid lubricant and additive of lubricating oil, is thought to be responsible for its excellent lubricating performances. However, the quantitative frictional properties between MoS2 atomic layers have not been directly tested in experiments due to the lack of conventional ...

Superlubrication by phonon confinement
Physical Review B, 2018The superlubrication described here, involving confined phonons, is easily achievable and very simple because it uses only submicron islands, smaller than the mean free path of the phonons, to confine phonons. We can achieve superlubrication with a friction force of piconewton order at the submicron island. We can call this phononic lubrication or self-
