Quantitative control of a rotary carbon nanotube motor under temperature stimulus
TLDR
This work presents a mathematical relationship between the rotor's speed and interaction energy, which is promising for designing a controllable temperature-driven rotary motor based on DWCNTs with length of few nanometers only.Abstract:
Since a double-walled carbon nanotube (DWCNT)-based rotary motor driven by a uniform temperature field was proposed in 2014, how to control quantitatively the rotation of the rotor is still an open question. In this work, we present a mathematical relationship between the rotor's speed and interaction energy. Essentially, the increment of interaction energy between the rotor and the stator(s) determines the rotor's rotational speed, whereas the type of radial deviation of an end carbon atom on the stator determines the rotational direction. The rotational speed of the rotor can be specified by adjusting temperature and radial deviation of an end carbon atom on the stator. It is promising for designing a controllable temperature-driven rotary motor based on DWCNTs with length of few nanometers only.read more

Significance tests on the output power of a thermally driven rotary nanomotor
TL;DR: Using stepwise regression analysis, it is discovered that N has the greatest influence on the output power of a nanomotor, while the diameter of the rotor, and the interaction between N and the diameter, respectively are the second and the third main factors.
