“…Because the shells in multi-walled carbon nanotubes have a little friction, they can easily move relative to each other [66]. Numerous nanomachines have been developed using materials like MWCNTs or double-walled carbon nanotubes (DWCNTs), such as bearings [27] and motors [67], because of their unique properties. The DWCNT can be considered as a rotor (inner tube) and a stator (outer tube) [62].…”

Due to the hollow cylindrical structure of CNTs, they are employed in the construction of nanomachines. Different types of CNT-based nanomachines have been designed and fabricated, so far. In these CNT-based nanomachines, the transportations of cargos are available along the length of nanotubes. In other cases, carbon nanotubes have been utilized to build rotary molecular machines, in which we observe the rotation of molecular objects around the nanotubes axis. Moreover, the carbon nanotubes have the potential to be used as gigahertz oscillators. In this chapter, we review some basic ideas of using nanotubes in the structure of nanomachines. The controllable mechanical motions have been reported in the CNT-based nanomachines, through the experimental and computational studies. Achieving the favorable precise movements at nano-scale is one of the most fascinating topics in the field of nanotechnology.

“…Driven by the van der Waals interaction, graphene with exceptional electrical [1][2][3], thermal [4][5][6], mechanical [7][8][9] properties yet extreme flexibilities [10,11] is prone of selffolding [12,13] and self-tearing [14], leading to the twodimensional (2D) to three-dimensional (3D) configuration transition and sequential complex spatial structures, such as ribbon [15], foams [16] and polyhedral [17,18], in a load-free and self-assembly [19][20][21] manner. This promises various engineering and potential applications, including straininsensitive sensors [22][23][24], stretchable electronics [25], water desalination [26], thermal transparency and thermoelectric material [27,28], nanomotors [29], heat management systems [30], walking devices [31] and biosensing skin [32].…”

The two-dimensional to three-dimensional configuration transition through self-tearing promises the engineering and promising applications of graphene. However, it is challenging to control the tearing path on demand through common thermal and interfacial treatments. In this manuscript, a defect-guided self-tearing technique is proposed to generate wider, longer, and even curved and serrated configurations, which is impossible for defect-free graphene. The underlying tearing mechanisms are disclosed through molecular dynamics simulations and theoretical model. This study provides a useful guidance to the implementation of complex and functional three-dimensional graphene structures.

“…Controlling mass transportation enables a wide range of applications, [1][2][3][4][5][6][7][8] such as the design and fabrication of nanoelectromechanical systems, [9][10][11][12][13] particle separation, [14,15] drug delivery, [16,17] and energy conversion. [18,19] There are many ways to control mass transportation, such as the simplest transmission method of gravity, the impact of channels geometric, [20] and defects [21] on water transport behavior, phonon induction that causes the movement of water nanodroplets [22] and external excitation that causes impact response.…”

Controlling mass transportation using intrinsic mechanisms is a challenging topic in nanotechnology. Herein, we employ molecular dynamics simulations to investigate the mass transport inside carbon nanotubes with temperature gradients, specifically the effects of adding a static carbon hoop to the outside of a CNT on the transport of a nanomotor inside the CNT. We reveal that the underlying mechanism is the uneven potential energy created by the hoops, i.e., the hoop outside the CNT forms potential energy barriers or wells that affect mass transport inside the CNT. This fundamental control of directional mass transportation may lead to promising routes for nanoscale actuation and energy conversion.
