Sudden stoppage of rotor in a thermally driven rotary motor made from double-walled carbon nanotubes [PDF]

, 2016
In a thermally driven rotary motor made from double-walled carbon nanotubes, the rotor (inner tube) can be actuated to rotate within the stator (outer tube) when the environmental temperature is high enough.

Unsteady loads for coaxial rotors in forward flight computed using a vortex particle method [PDF]

, 2018
Recent advances in coaxial rotor design have shown benefits of this configuration. Nevertheless, issues related to rotor-head drag, aerodynamic performance, wake interference, and vibration should also be considered.

An $U_{qp}(u_2)$ Rotor Model for Rotational Bands of Superdeformed Nuclei [PDF]

, 1995
A nonrigid rotor model is developed from the two-parameter quantum algebra $U_{qp}({\rm u}_2)$. [This model presents the $U_{qp}({\rm u}_2)$ symmetry and shall be referred to as the qp-rotor model.] A rotational energy formula as well as a qp-deformation

Bistable molecular conductors with a field-switchable dipole group

, 2002
A class of bistable "stator-rotor" molecules is proposed, where a stationary bridge (stator) connects the two electrodes and facilitates electron transport between them.
