Structural characterization of nanomaterials C 4 C 8

AbstractTopological indices are the numerical parameters of molecular graphs that characterise their behaviour and are mathematical invariant that preserves chemical and material properties. In a QSAR/QSPR study, physico-chemical properties and topological indices are studied. In this research, we shall calculate forgotten topological, inverse sum, the general sum connectivity and the first multiplicative atom–bond connectivity indices of carbon nanotube TUC4C8[m,n] and C4C8[m,n] nanotorus. The main motivation here is the molecular graphs of the nano-chemical compound TUC4C8 nanotubes and C4C8 nanotorus. While the central and latest point of convergence of our discussion is to provide a ‘3D graphical trend and relative comparison’ of these derived topological descriptors of these materials that will make them more useful and comparative for chemists, nano and material scientists and would open a new 3D graphical horizon towards material sciences and chemical engineering.Keywords: Forgotten indexatom–bond connectivity indexTUC4C8 nanotubeC4C8 nanotorus Disclosure statementNo potential conflict of interest was reported by the author(s).
