(Sami Publishing Company, 2023) Sardar, M.S.; Ali, M.A.; Ashraf, F.; Cancan, M.
Silicon is a semiconductor material with several advantages over the other similar materials, such as its low cost, nontoxicity, and almost limitless availability, as well as many years of expertise in its purification, manufacture, and device development. It is used in practical for all of the most recent electrical products. Graph theory can be used to depict a chemical structure, with vertices representing atoms and edges representing chemical bonds. Molecular descriptors are important in mathematical chemistry, particularly in QSPR/QSAR research. In this research, by using two graph operations, namely; double and strong double graph, we computed the closed formulas for some degree-based topological indices of silicon carbide. Furthermore, we also compare topological indices numerically and graphically. Copyright © 2023 by SPC.
Study of Middle Graph for Certain Classes of Graph by Applying Degree-Based Topological Indices
(Sami Publishing Company, 2023) Sardar, M.S.; Ali, M.A.; Ashraf, F.; Cancan, M.
Topological indices are extremely useful for analyzing various physical and chemical properties associated with a chemical compound. A topological index describes molecular structures by converting them into certain real numbers. Topological indices are used in the development of quantitative structure-activity relationships (QSARs) in which the biological activity of molecule correlated with their chemical structure. The chemical shape of benzene molecule is very common in nano-science, chemistry, and physics. The circumcoronene collection of benzenoid (Hs) generates from the benzene molecules. Jahangir graph (J(m,t)) is a generalized wheel graph that consists of (m, t) circular vertices and a center vertex connected to every mt vertex on the circle. In this article, we will compute the topological indices of the middle graph of the circumcoronene series of benzenoids (Hs) and Jahangir graph (J(m,t)). In addition, comparison of the middle graph of the circumcoronene series of benzenoid (Hs) and Jahangir graph (J(3,t)) are presented numerically and graphically. Copyright © 2023 by SPC.
