With reference to the paper [27], the free frequencies of double-walled carbon nanotubes (DWCNTs), [[OMEGA].sub.i] [4th root of ([[omega].sup.2.sub.i]([rho][A.sub.T][L.sub.4]/[EI.sub.T])], with [I.sub.T] = [I.sub.1] + [I.sub.2] and [A.sub.T] = [A.sub.1] + [A.sub.2], are calculated.
Recently, Hemmatnezhad and Ansari [31] have furnished a finite element formulation for the free vibration analysis of embedded double-walled carbon nanotubes based on nonlocal Timoshenko beam theory.

Then we solved the equations by considering the effect of nano scale, Van der Waals forces between the inner and outer carbon nanotubes for double-walled carbon nanotubes in equations of motion, and buckling modes by applying the boundary conditions of the simple fulcrum as sine functions," he added, noting, "Next, we calculated the natural frequencies.
In general, these nanotubes can be classified into single-walled carbon nanotubes, double-walled carbon nanotubes, and multiwalled carbon nanotubes.

It is in general accepted that carbon nanostructure is classified into three regimes, based on the prepared catalyst thickness: single-or double-walled carbon nanotubes on the thin catalyst less than 1nm [18-20], precipitated graphene on two orders of magnitude thicker catalysts [21-23], and Carbon nanofibers (CNFs) or multiwalled carbon nanotubes (MWCNTs) on the intermediately sized catalyst [24-26], meaning that the initial catalyst thickness is one of the key factors to decide the shape of carbon allotropes.
