TL;DR: In this paper, anisotropic mechanical properties are observed for a sheet of graphene along different load directions, attributed to the hexagonal structure of the unit cells of the graphene, and it is shown that the loading and unloading stress-strain response curves overlap as long as the graphene is unloaded before the fracture point.

TL;DR: In this article, Monte Carlo simulation is applied to investigate phonon transport in single crystalline Si nanowires, and two different phonon dispersions, one from experimental measurements on bulk Si and the other solved from elastic wave theory, are adopted in the simulation.

TL;DR: In this article, the dependence of superlattice thermal conductivity on period length is investigated by molecular dynamics simulation, and the simulation results are consistent with phonon transmission coefficient calculations, which indicate increased stop bandwidth and thus strongly enhanced Bragg scattering.

TL;DR: Silicon nanowires were synthesized in situ in parallel silicon microchannel arrays for the first time to suppress the flow instability and to augment flow boiling heat transfer.

TL;DR: In this paper, the authors demonstrate enhanced condensation heat transfer on a nanowired hydrophobic copper surface where molecular permeation of water vapor into the separations between nanowires is greatly decreased, rendering spatial control on droplet nucleation and wetting dynamics.
