M-Polynomials and Degree-Based Topological Indices of VC₅C₇[p,q] and HC₅C₇[p,q] Nanotubes

Analysts are creating materials, for example, a carbon nanotube-based composite created by NASA that bends when a voltage is connected. Applications incorporate the use of an electrical voltage to change the shape (transform) of airship wings and different structures. Topological indices are numerical parameters of a molecular graph which characterize its topology and are usually graph invariant. Topological indices are used, for example, in the...
