Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

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

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …

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 …

This paper reviews recent progress in molecular dynamics simulation of atomic-scale friction
measured by an atomic force microscopy. Each section of the review focuses on an …

Grain boundaries (GBs) play a crucial role in the mechanical behaviors of nanocrystalline
materials. The dynamics of GBs depend on a variety of intrinsic and extrinsic factors …

The atomic stick-slip behavior of a Pt tip sliding on a Au (111) surface is studied with atomic
force microscopy (AFM) experiments and accelerated (ie, reduced sliding speed) molecular …

Control over grain boundary (GB) motion ways provides an effective mean for tailoring the
mechanical and physical properties of nanocrystalline metals. However, shear direction …

The evolution of grain boundary (GB) networks in polycrystalline metals depends not only on
the movement of the constituent GBs but also on the migration of GB triple junctions (TJs) …

Computational modelling techniques are now widely employed in materials science, due to
recent advances in computing power and simulation methodologies, since they can enable …
