ABSTRACT
Parametric oscillations are observed in torsional electromechanical oscillators based on carbon nanotubes via molecular dynamics simulations. The stretch of nanotube torsion springs due to the vertical translational-electrostatic force acting on the paddle makes possible the parametric oscillations. The electrostatic force can provide control over nanotube stretching that allows it to parametrically modulate the torsional spring constant at twice the resonance frequency. This reveals potential building blocks for a variety of applications of the devices.

    Transport of water through narrow pores is important in chemistry, biology and material science. In this work, we employ atomistic molecular dynamics (MD) simulations to carry out a comparative study of the transport of a polar and a non-polar solvent through a carbon nanotube (CNT). The flow of...

Otherwise, the descriptions of dynamic disturbances in such media...
