Buckling of double-walled carbon nanotubes [PDF]

open access: yesVietnam Journal of Mechanics, 2012
In this note we deal with the approximate solution of the buckling problem of a clamped-free double-walled carbon nanotube. First the finite difference method is utilized to solve this case. Then this approach is verified by solving the buckling problem

A Review of Double-Walled and Triple-Walled Carbon Nanotube Synthesis and Applications

open access: yesApplied Sciences, 2016
Double- and triple-walled carbon nanotubes (DWNTs and TWNTs) consist of coaxially-nested two and three single-walled carbon nanotubes (SWNTs). They act as the geometrical bridge between SWNTs and multi-walled carbon nanotubes (MWNTs), providing an ideal ...
