The physics of sliding friction is gaining impulse from nanoscale and mesoscale
experiments, simulations, and theoretical modeling. This Colloquium reviews some recent …

As the size of electronic and mechanical devices shrinks to the nanometre regime,
performance begins to be dominated by surface forces. For example, friction, wear and …

A mechanical-loading stage operating inside a scanning electron microscopy (SEM) was
used to realize the sliding between nested shells of multiwalled carbon nanotubes …

In this paper, a new kind of oil-soluble ultrathin MoS2 nanosheets is prepared through a one-
pot process. A superior extreme pressure property, which has not been attained with other …

A microscopic theory for the ubiquitous phenomenon of static friction is presented.
Interactions between two surfaces are modeled by an energy penalty that increases …

Using atomistic models and molecular dynamics simulations, interlayer corrugation and
resistant force in a biwalled carbon nanotube are shown to be strongly dependent upon the …

Friction is one of the oldest problems in physics with a huge practical significance. However,
during the last decade this problem gets strong acceleration due to the development of new …

A sheared microscopic graphite mesa retracts spontaneously to minimize interfacial energy.
Using an optical knife-edge technique, we report first measurements of the speeds of such …

The goal of this chapter is to review statistical mechanical approaches to the molecular
origins of friction. A brief outline of macroscopic experimental results and the fundamental …

The friction of graphene depends on thickness, but little is known how it is dependent on
stiffness. Based on a graphene-spring model, using molecular dynamics simulations, we …
