Second Hyper-Zagreb Index of Titania Nanotubes and Their Applications [PDF]
IEEE Access, 2021 Topological index is a numerical descriptor of a molecule, based on a certain topological feature of the corresponding molecular graph, it is found that there is a strong correlation between the properties of chemical compounds and their molecular ...

Topological Properties of Degree-Based Invariants via M-Polynomial Approach
Journal of Mathematics, 2022 Chemical graph theory provides a link between molecular properties and a molecular graph. The M-polynomial is emerging as an efficient tool to recover the degree-based topological indices in chemical graph theory.
