Abstract

A nanostructure belong to a significant and an extensively investigated compounds in chemical science. It has been derived through engineering mechanism at the molecular scale. The most important of these new materials are carbon nanotubes. Carbon nanosheets are 2-dimensional lattices of carbon nanotubes. To compute and study topological indices of nanostructures are a respected problem in nanotechnology. Quantitative structure-property and structure-activity relationships of the carbon nanotubes compounds necessitate expressions for the molecular topological features of these compounds. Topological indices are vital devices for investigating chemical compounds to comprehend the fundamental topology of chemical structures. Ev-degree and ve-degree based topological indices are two novel degrees based indices as of late defined in chemical graph theory. In this paper, we have computed topological indices based on ev-degree and ve-degree for the two significant classes of carbon nanosheets composed by C₄ and C₈ denoted by $T^1{C}_4{C}_8(S)[p,q]$ and $T^2{C}_4{C}_8(R)[p,q].$

摘要

纳米结构属于化学科学中重要且广泛研究的化合物。它是通过分子尺度的工程机制获得的。这些新材料中最重要的是碳纳米管。碳纳米片是碳纳米管的二维晶格。计算和研究纳米结构的拓扑指数是纳米技术中一个受人尊敬的问题。碳纳米管化合物的定量结构-性质和构效关系需要表达这些化合物的分子拓扑特征。拓扑指数是研究化合物以了解化学结构的基本拓扑的重要工具。基于 Ev 度和 ve 度的拓扑指数是化学图论中最近定义的两个新的基于度的指数。在本文中，我们计算了基于 ev-degree 和 ve-degree 的两个重要类别的碳纳米片的拓扑指数：C ₄和C ₈表示为${吨}^1{C}_4{C}_8(\mathrm{小号})[p,q]$和${吨}^2{C}_4{C}_8(R)[p,q].$
