ABSTRACT
Theoretical study and molecular dynamics simulations are performed to investigate the gigahertz “breathing” oscillatory motion of a carbon nanoscroll (CNS). It is shown that the oscillation frequency depends on surface energy, bending stiffness, interlayer spacing, and length of the basal graphene sheet of the CNS, and that energy dissipation in the system can be controlled by adjusting temperature, graphene length, and surface energy. The analysis indicates potential applications of CNS in nanomechanical devices such as nanooscillators, nanoactuators, as well as drug and gene delivery systems.

    Some of the pitfalls that may befall molecular simulations of interfaces are discussed. They are all related to the calculation of the pressure tensor profiles, which are needed in order to compute surface tensions. We focus on three controversial points: (1) the calculation of the pressure...

    We report molecular dynamics computer simulations of the surface tension and interfacial thickness of ionic liquid-vapor interfaces modeled with a soft core primitive model potential. We find that the surface tension shows an anomalous oscillatory behavior with interfacial area. This observation...

    We use molecular dynamics computer simulations to study the equilibrium properties of the surface of amorphous silica. Two types of geometries are investigated: (i) clusters with different diameters (13.5, 19, and 26.5 Ã…) and (ii) a thin film with thickness 29 Ã…. We find that the shape...

    Based on thermodynamic perturbation theory, we calculate the surface tension for aluminium nanodrops of various radii. The size dependence obtained with the Schommers potential is compared with the results corresponding to other effective pair potentials. It is stated that the asymptotic value...

    We demonstrate that thermocapillary forces may drive bubbles against liquid flow in 'anomalous' mixtures. Unlike 'ordinary' liquids, in which bubbles migrate towards higher temperatures, we have observed vapour bubbles migrating towards lower temperatures, therefore against the flow. This...

    The way fluids flow into and fill nanotubes is of wide interest; however, there are currently no experimental data or validated theoretical models for this nanoscale process.
