Thermodynamic properties of chiral BN nanotubes and their dependence on molecular diameter

The study of the properties of nanotubes for physical and chemical applications has yielded many highly useful and effective results in different areas ofscience. The structure of a single-wall nanotube is determined by the orientation of the hexagonal ring of carbon atoms in the honeycomb lattice relative to thenanotube's axis. In this study the relationship between some of thermodynamics properties such as thermal capacity (ΔCv ), entropy (ΔS), energy (ΔE),enthalpy(ΔH), Gibbs free energy (ΔG) of 10 different type of boron nitride (BN) chiral nanotubes in contrast to their diameter are presented [1-4].
