A Novel Exact Plate Theory for Bending Vibrations Based on the Partial Differential Operator Theory
Mathematics, 2021 Thick wall structures are usually applied at a highly reduced frequency. It is crucial to study the refined dynamic modeling of a thick plate, as it is directly related to the dynamic mechanical characteristics of an engineering structure or device ...

Dynamics of a nano-scale rotor driven by single-electron tunneling [PDF]
EPL, 98 (2012) 68004, 2012 We investigate theoretically the dynamics and the charge transport properties of a rod-shaped nano-scale rotor, which is driven by a similar mechanism as the nanomechanical single-electron transistor (NEMSET). We show that a static electric potential gradient can lead to self-excitation of oscillatory or continuous rotational motion.
