In this paper, we study the edge version of some degree based topological indices such as general sum-connectivity index, Randic index, inverse sum indeg index, symmetric division deg index, augmenting Zagreb index and harmonic polynomial for joint graphs and certain graph operations.

Using density functional theory calculations, we investigated properties of a functionalized carbon nanotube with one mercarzole molecule as a benzimidazole fungicide. Three different configurations are possible depending on the type of functional group used in the structure of mercarzole. We investigated different electronic properties for these configurations such as adsorption energy, band gap energy and charge transfer effects. As a consequence of structural properties the adsorption height and the most stable adsorption configuration are also discussed. It has been found that a mercarzole molecule is adsorbed on the tube surface with adsorption energies in the range of −0.01 to −0.67 eV, and their relative magnitude order is found as follows: imin group > ester group > amin group. Obtained results reveal important features of the adsorption mechanism of mercarzole molecules onto the functionalized carbon nanotubes. This study can be used in farming researches in order to improving cultivation and wellbeing human.

On certain degree-based topological indices of armchair polyhex nanotubes
Rachanna
Kanabur
Recently [18], Shigehalli and Kanabur have introduced two new topological indices namely, AG2 index and SK3 index. Hosamani [14], has studied a novel topological index, namely the Sanskruti index S (G) of a molecular graph G. In this paper, formula for computing the armchair polyhex nanotube TUAC6 [m, n] family is given.
