Abstract
  φp-Polynomial is one way to represent a graph algebraically, and it has a major role in theoretical chemistry. It is used in the calculation of the exact values of many topological indices that depend on the P set degree. In this paper, we study the φp-Polynomial by using minimal and minimum ...  Read More

Articles in Press, Accepted Manuscript, Available Online from 15 March 2021

http://dx.doi.org/10.22034/ecc.2021.274069.1138

Abstract
  In this paper, for every k-degree distance we define ψk-Polynomial of a connected graph G=(V,E) as  where ψk(i,j) is the number of edges uv in G such that {dk(v), dk(u)}={i,j} and dk(v), dk(u) are the kth degree distance of v and u, and δk, ∆k are the minimum and maximum kth distance degrees respectively. ...  Read More

http://dx.doi.org/10.22034/ecc.2021.277385.1148

Abstract
  In summary, NPs help in reducing the IFT either alone or in combination with surfactants. Moreover, NPs can also reduce the adsorption of surfactants on reservoir rock surface. However, additional experimental work is required to understand the underlying mechanism of improvement in interfacial properties ...  Read More
