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

Soon after the discovery of carbon nanotubes, it was realized that the theoretically predicted
mechanical properties of these interesting structures–including high strength, high stiffness …

A common misconception is that the irradiation of solids with energetic electrons and ions
has exclusively detrimental effects on the properties of target materials. In addition to the …

We present an atomic cluster expansion (ACE) for carbon that improves over available
classical and machine learning potentials. The ACE is parametrized from an exhaustive set …

Fullerene single-wall nanotubes (SWNTs) were produced in yields of more than 70 percent
by condensation of a laser-vaporized carbon-nickel-cobalt mixture at 1200° C. X-ray …

We present a density-functional-based scheme for determining the necessary parameters of
common nonorthogonal tight-binding (TB) models within the framework of the linear …

We investigate the mechanical strength and properties of graphene under uniaxial tensile
test as a function of size and chirality using the orthogonal tight-binding method and …

Single wall carbon nanotubes (SWNTs) that are found as close-packed arrays in crystalline
ropes have been studied by using Raman scattering techniques with laser excitation …

We present a method for reliably determining the lowest energy structure of an atomic
cluster in an arbitrary model potential. The method is based on a genetic algorithm, which …

Hybridization of the σ* and π* states of the graphene network is shown to be as important as
band-folding effects in determining the metallicity of small radius carbon nanotubes. Using …
