Computation of Revan Topological Indices for Phenol-Formaldehyde Resin

open access: yesJournal of Mathematics, 2022
Phenol-formaldehyde resin has a wide range of moldings. The phenolic resin retains properties at the freezing point; hence, it is difficult to determine its age.

Computation of Topological Indices of Some Special Graphs

open access: yesMathematics, 2018
There are several chemical indices that have been introduced in theoretical chemistry to measure the properties of molecular topology, such as distance-based topological indices, degree-based topological indices and counting-related topological indices ...

Downhill Zagreb Topological Indices of Graphs [PDF]

open access: yesInternational Journal of Analysis and Applications, 2021
Topological indices are graph invariants determined by the distance or degree of vertices of the molecular graph. Topological indices have been used effectively in chemical graph theory in explaining the structures and predicting certain physicochemical ...

Topological indices for nanoclusters [PDF]

open access: yesComputational Materials Science, 2015
Abstract Nanoclusters create the possibility of designing novel properties and devices based on finite structures, with small dimensions. Clusters are of interest for catalytic, optical, biochemical, and structural characteristics. We examine clusters of icosahedral, cuboctahedral, and decahedral symmetry.

GTI-space : the space of generalized topological indices [PDF]

open access: yes, 2008
A new extension of the generalized topological indices (GTI) approach is carried out torepresent 'simple' and 'composite' topological indices (TIs) in an unified way.

Topological Descriptors on Some Families of Graphs

open access: yesJournal of Chemistry, 2021
In view of the successful applications of graph theory, relationships between the biological activity and chemical structure have been developed. One of the popular topics in graph theory is problems relating to topological indices.

Topological Descriptors and Polynomials for Analysing the Structure of Antimony Telluride

open access: yesJournal of Mathematics, 2022
In a molecular network, molecules are correlated with numerical values, which are referred to as topological indices. The chemical and physical properties of chemical substances can be determined using topological indices.

Affine Graphs and their Topological Indices [PDF]

open access: yesJournal of Mathematics, 2021
Graphs are essential tools to illustrate relationships in given datasets visually. Therefore, generating graphs from another concept is very useful to understand it comprehensively. This paper will introduce a new yet simple method to obtain a graph from any finite affine plane.
