- Abstract
The ultrathin channel in nanotube is an exciting host to encapsulate sub-nanometer size guest spices. The dynamics of confined C 60 s inside the nanoscale host tube have been investigated by various stimuli like e-beam irradiation, Ar-ion laser and Cu K α X-ray. It has been disclosed that the accelerating voltage of TEM higher than the threshold energies of the ballistic knockoff in carbon atoms can be used to understand the rotation of host species in the confined geometry. The radial breathing Raman mode of host SWCNTs has been studied to insight into the enhanced mobility of guest C 60 s at higher temperatures in the confined tube geometry of nanopeapod. We have highlighted the role of temperature as a function of kinetic energy of the confined C 60 s in SWCNTs and which leads to the reduction of stress in host–guest complex. The temperature-dependent XRD has been used to study the mobilities of C 60 molecules adsorbed onto the SWCNTs to move along the tube walls until they detect an opening to infuse in the confined space
