3. New results on eccentric connectivity indices of V-Phenylenic nanotube
Volume 2, Issue 6 , June 2020, Pages 663-671
Abstract
Topological index is a type of molecular descriptor calculated based on the molecular graph of a chemical compound. Topological indices are used for developing the quantitative structure activity relationships (QSARs) in which the biological activity or other properties of the molecules are correlated ...

4. Computation of bond incident degree (BID) indices of complex structures in drugs
Volume 2, Issue 6 , June 2020, Pages 672-679
Abstract
The molecular topological descriptors are the numerical in-variants of a molecular graph and are very useful and efficient to predict their bioactivity. Dendrimers are highly branched organic macro-molecules with successive layers or generations of branch units surrounding a central core and have many ... Read More

Volume 2, Issue 6 , June 2020, Pages 680-687
Abstract
In this article, we study the degree based molecular topological indices for some infinite families of Nanostar Dendrimers. We derive the analytical closed formulae for these classes of complex chemical networks. These results are very helpful in understanding and predicting the physico-chemical properties ... Read More
6. Phosphomolybdic acid immobilized chitosan/Fe3O4: an efficient catalyst for the N-alkylation of anilines
Volume 2, Issue 6 , June 2020, Pages 688-701
Abstract
In this work, phosphomolybdic acid immobilized on chitosan/Fe3O4 as a green catalyst was used for the Hofmann N-alkylation of aniline derivatives with alcohols. H3PMo12O40/chitosan/Fe3O4 (PMo/Chit/Fe3O4) was prepared from the phosphomolybdic acid, chitosan, and Fe3O4 MNPs. Several secondary amines were ... Read More
7. Nano-molar level determination of isoprenaline in pharmaceutical and clinical samples; A nanostructure electroanalytical strategy
Volume 2, Issue 6 , June 2020, Pages 702-711
Abstract
A high sensitive electroanalytical-based sensor for determination of isoprenaline was fabricated by modification of carbon paste electrode (CPE) by NiO-Pt-Pd/CNTs composite as conductive mediator and n-hexyl-3-methylimidazolium hexafluoro phosphate (NHIHP) as conductive binder. The NHIHP/NiO-Pt-Pd/CNTs/CPE ... Read More
8. Eccentric connectivity indices of titania nanotubes TiO2[m;n]
Volume 2, Issue 6 , June 2020, Pages 712-721
Abstract
The eccentric connectivity index ECI is a chemical structure descriptor that is currently being used for modeling of biological activities of a chemical compound. This index has been proved to provide a high degree of predictability compared to some other well-known indices in case of anticonvulsant, ...

9. Improving the separation process of fine particles in drilling mud by ultrasonic waves
Volume 2, Issue 6 , June 2020, Pages 722-730
Abstract
Aggregation of solid particles in the drilling fluid has adverse effects on the drilling performance, including blocking drilling pipe, reducing fluid lubrication, and the blowout action. The purpose of this study was to prepare a solution for breaking the adhesion forces between the suspended solids ... Read More
10. Study of some topological invariants of subdivided mk graphs
Volume 2, Issue 6 , June 2020, Pages 731-738
Abstract
An mk-graph of a graph G can be defined by taking m≥2 copies G1,..., Gm of a graph G in which every vertex ut of copy Gt is adjacent to a corresponding vertex vs of copy Gs. An mk-graph is represented by mk(G). In this research study, we discussed some degree based topological indices (connectivity ... Read More
