ABSTRACT
In the current manuscript, an approach to modeling and simulation of single-wall carbon nanocones (SWCNC) has been suggested for mass sensing applications. Finite element modeling and dynamic analysis of SWCNC with cantilever beam boundary condition, various disclination angles of 60°, 120°, 180°, 240°, 300° and 10, 15, 20 A° lengths have been completed using atomistic molecular structure. This study has been conducted to evaluate and identify the difference in fundamental frequencies shown by these nanodevices when subjected to sensing applications. The study also displays the outcome of alteration in the length of nanocones on the vibrational frequencies. It is witnessed that increasing length of a SWCNC with the same apex angle outcomes in a drop in the fundamental frequency. Additionally, it is clear from the outcomes that SWCNC with greater apex angles displays lesser values of fundamental frequencies. Original and defective single-walled nanocones have been analyzed to study the effect of defects like vacancy defect and Stone-Wales defect. The results show the fact that with the change in the disclination angle and defects there is a significant amount of variation in the stiffness due to the different position on defects in nanocones. The outcomes propose that 80smaller lengths of nanocones are good contenders for sensing applications as they display extensive variation in the fundamental frequencies. It also shows that as the mass increases a certain limit.
