    On Eccentricity-Based Entropy Measures for Dendrimers
    (Elsevier Sci Ltd, 2021) Huang, Rongbing; Siddiqui, Muhammad Kamran; Manzoor, Shazia; Ahmad, Sarfraz; Cancan, Murat
    The eccentricity-based entropy inspired by Shannon's entropy approach is the information-theoretic quantity to figure out the structural information of complex networks. The investigation for advance biomedical utilization of dendrimers has improved the synthesis of radical based molecules. Categorically, attaining radical dendrimers has initiated their use in different fields such as anti-tumor agents and as magnetic resonance imaging. The use of radical dendrimers has increased the possibility of establishing new kinds of devices based on paramagnetic axioms of organic radicals. In this article, we discussed dendrimer based on cyclotriphosphazene (N3P3) which has balanced edge groups and these are examined by EPR temperature spectrum. Firstly, we computed eccentricity-based indices and then we computed eccentricity based entropies by developing an acquaintance between these indices and their entropies. Moreover we presented our computed result numerically and graphically which leads to good importance of our contribution.

    Topological Properties of Nanostar Dendrimer and Smart Polymer
    (Hindawi Ltd, 2020) Rashid, Muhammad Aamer; Ahmad, Sarfraz; Cancan, Murat; Muhammad, Mehwish Hussain
    The nanostar dendrimers are a piece of another gathering of macromolecules that seem, by all accounts, to be photon pipes simply like counterfeit reception apparatuses. In addition, nanostar dendrimers are one of the fundamental stuffs of nanobiotechnology. The smart polymers are large-scale particles that show an emotional physioconcoction change because of little changes in their condition, for example, temperature, pH, light, attractive field, and ionic variables. A topological record of a graph G is a numeric quantity notorious with G which portrays subatomic diagram G. In this paper, we decide first and second Zagreb indices, hyper-Zagreb index, first multiple Zagreb index, second numerous Zagreb index, and Zagreb polynomials for nanostar dendrimer and smart polymer.
