(Taylor & Francis Ltd, 2022) Zhao, Weidong; Nadeem, Muhammad Faisal; Cancan, Murat; Siddiqui, Muhammad Kamran; Ali, Kashif; Siddiqui, Hafiz Muhammad Afzal; Kanwal, Salma
In this paper, we discuss the degree based topological properties of the novel planar metal-organic networks TM - TCNB. Interestingly, the TM - TCNB systems are metallic in any event in one turn heading and show long-run ferromagnetic coupling on the off chance that for attractive structures, which speak to perfect applicants and a fascinating possibility of uncommon applications in spintronics. Chemical graph theory plays an important role in modeling and designing any chemical structure. The topological indices are the numerical invariants of a molecular graph and are very useful for predicting their physical properties. We have computed the degree based topological indices for this metal-organic networks TM - TCNB.
The Sharp Bounds of Zagreb Indices on Connected Graphs
(Element, 2021) Chu, Yu-Ming; Shafiq, Muhammad Kashif; Imran, Muhammad; Siddiqui, Muhammad Kamran; Siddiqui, Hafiz Muhammad Afzal; Baby, Shakila; Cancan, Murat
The analysis of a structure is based on its configuration. The common means available for this purpose is the use of graph products. The rooted product is specially revelent for trees. Chemical application of graph theory predicts different properties like physico-chemical properties, thermodynamics properties, chemical activity, biological activity, etc. Certain graph invariants known as topological indices are used for characterization of these properties. These indices have a promising role in chemical sciences and QSAR/QSPR studies. In this paper the lower and upper bounds of Zagreb indices, multiple Zagreb indices and F-index for rooted product of F-sum on connected graphs are determined.
