    On Analysis of Temperature Based Topological Indices of Some Covid-19 Drugs
    (Taylor & Francis Ltd, 2023) Zhang, Yang; Khalid, Asma; Siddiqui, Muhammad Kamran; Rehman, Haider; Ishtiaq, Muhammad; Cancan, Murat
    A variety of graphical invariants have been described and tested, offering lots of applications in the fields of nanochemistry, computational networks and in different scientific research areas. One commonly studied group of invariants is the topological index, which allows to research the chemical, biological, and physical properties of a chemical structure. Topological indexes are numerical quantities that can be used to describe the properties of the molecular graph. In this article, we draw from the analytically closed formulas of certain molecular structures of coronavirus such as Ribavirin, Sofosbuvir and Oseltamivir by calculating temperature based topological indices.

    Topological Study of Carbon Nanotube and Polycyclic Aromatic Nanostar Molecular Structures
    (Taylor & Francis Ltd, 2022) Luo Guangyu; Hussain, Sajjad; Khalid, Asma; Ishtiaq, Muhammad; Siddiqui, Muhammad Kamran; Cancan, Murat; Imran, Muhammad
    Nanomaterials are chemical compounds or substances which are moderately produced and used. Nanomaterials are engineered to reveal novel properties of nanocells that contrast with related non-visible substances, such as expanded consistency, conductivity or synthetic reaction. Topological indexes are quantities related to molecules that capture the harmony of molecular structures and give scientifically related properties, such as: viscosity, boiling point, radius of gravity, and so on. Their demands in genetics, chemistry, physics and nanoscience are infinite. The molecular topology of such compounds would be clarify by the quantitative structure properties relationship (QSPR) and quantitative structure activity relationship (QSAR). Two carbon nanosheet structures such as TC4C8(s)and dentritic nanostar have been discussed in this article, We have computed topological indices of these structures such as the first and the second K-Banhatti types indices and their variants.
