Valency-Based Descriptors for Silicon Carbides, Bismuth(III) Iodide, and Dendrimers in Drug Applications

Abstract

Silicon carbide (SiC), also called carborundum, is a semiconductor containing silicon and carbon. Dendrimers are repetitively branched molecules that are typically symmetric around the core and often adopt a spherical three-dimensional morphology. Bismuth(III) iodide is an inorganic compound with the formula BiI3. This gray-black solid is the product of the reaction between bismuth and iodine, which once was of interest in qualitative inorganic analysis. In chemical graph theory, we associate a graph to a compound and compute topological indices that help us in guessing properties of the understudy compound. A topological index is the graph invariant number, calculated from a graph representing a molecule. Most of the proposed topological indices are related either to a vertex adjacency relationship (atom-atom connectivity) in the graph or to topological distances in the graph. In this paper, we aim to compute the first and second Gourava indices and hyper-Gourava indices for silicon carbides, bismuth(III) iodide, and dendrimers.

On Alpha and Gamma Gourava Indices

“…Recently some Gourava indices were studied, for example, in [12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

Analysis of Bismuth (III) Iodide and Dendrimers in Drug Applications

“…Because of their effects against prion disorders, Alzheimer's disease, inflammation, HIV, herpes simplex virus (HSV), bacteria, and cancer, dendrimers are interested in medication research. We use the term "topological research of dendrimers" to refer to the study of dendrimers on a topological level [29,30]. Frequency 3.…”

“…We compute Sombor indices, multiplicative Sombor indices, and reduced Sombor indices for bismuth (III) iodide and dendrimers as well as their graphical representations, in this study [28][29][30].…”

Nirmala Alpha Gourava and Modified Nirmala Alpha Gourava Indices of Certain Dendrimers

“…Recently, some Gourava indices were studied in [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39].…”
