“…These forces generate sliding and rotary motions between the walls of MWCNTs. The oscillatory behavior and vdW interactions of CNTs have been a subject of wide interest, and numerous studies have been devoted to investigate their di erent features thus far [10][11][12][13][14][15][16][17].…”

Abstract. Electromechanical nanothermometers are instruments that work on the basis of the van der Waals (vdW) potential energy and interaction force of their constituent carbon nanotubes (CNTs). The CNT-based nanothermometers have two di erent con gurations: telescope and shuttle con gurations. In this article, based on the Lennard-Jones potential function together with the continuum approximation, rst, the vdW potential energy and interaction force for a telescope con guration with nite CNTs are derived, which have not been obtained in the previous research studies. Thereafter, by employing the interaction force, the equation of motion between constituent CNTs is solved. Subsequently, a new semi-analytical expression is obtained which enables one to precisely evaluate the oscillation frequency. By employing the given formulae, e ects of di erent system parameters on the vdW interactions and oscillation frequency are shown.

“…Ansari et al [11][12] studied the mechanical properties and vibrational behaviors of CNCs with use of spring-mass model and shell model, respectively. Furthermore, the same research team has taken the van der waals interaction into consideration to investigate the contact behaviors of CNCs with other nanomaterials [13][14][15]. Firouz-Abadi et al [16] proposed a nonlocal continuum shell model for the analysis of the stability of nanocones.…”

A temperature-related multiscale quasi-continuum (QC) model is presented herein for the investigation of the finite deformation behaviors, especially buckling and post-buckling, of open-tip single-walled carbon nanocones (SWCNCs) in thermal environments. The hyper-elastic constitutive model is established with the use of so-called temperature-related higher-order Cauchy-Born (THCB) rule as the kinematic
