Abstract

The invention of new nanostructures gives a key measurement to
industry, electronics, pharmaceutical and biological therapeutics. By considering
the importance of this key point, in here we compute the 2D-lattice,
nanotube and nanotorus of TUC4C8[p; q] over the graphs Q(G) and R(G)
in terms of certain topological indices, namely Örst, second and third Zagreb
indices, hyper Zagreb index and forgotten topological index. These indices
are numerical propensity that often characterizes the quantitative structural
activity/property/toxicity relationships, and also correlates physico-chemical
properties such as boiling point, melting point and stability of respective nanostructures.

Keywords

2D-lattice, nanotubes, nanotorus, first, second and third Zagreb indices, hyper Zagreb index, forgotten index
