1. Domination topological properties of some chemical structures using φp-Polynomial approach
Articles in Press, Accepted Manuscript, Available Online from 15 March 2021
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)
2. On the ψk-polynomial of graph
Articles in Press, Accepted Manuscript, Available Online from 15 March 2021
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. ...

3. Using new surfactants in EOR process for new cases to lower the oil water interfacial tension
Articles in Press, Accepted Manuscript, Available Online from 02 April 2021
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)
4. Effects of graphene oxide (GO) nanoparticle and SDS on storage capacity of CO2 in hydrate
Articles in Press, Accepted Manuscript, Available Online from 02 April 2021
Abstract
In this study, the effect of nanoparticle of graphene oxide and surfactant sodium dodecyl sulfate (sds) 400 ppm on the storage capacity of co2 in hydrate was investigated. A laboratory system was developed for hydrate formation experiments. The experiments were carried out in the range of pressure 36-40 ... Read More nanoparticle and SD ...

5. Phytochemical screening by using GC-MS and FTIR spectrum analysis of fixed oil from Sudanese Ziziphus spina Christi seeds
Articles in Press, Accepted Manuscript, Available Online from 03 April 2021
Abstract
The current trend of using natural products from the plants, either as pure constituents or as standardized extracts, provides numerous opportunities for novel drugs, precisely the wild edible plants. Ziziphus spina Christi plant is considered as one of the most important therapeutic and nutritional ... Read More)
6. On the ABC and GA indices of the corona products of some graphs
Articles in Press, Accepted Manuscript, Available Online from 07 April 2021
Abstract
In this research, we derived the formulae for the atom-bond connectivity (ABC) index and the geometric-arithmetic (GA) index of several corona products of graphs made by composing the path, the cycle and the complete graphs. Relevant mathematical results were presented with proofs, indicating the possibility ... Read More)

8. Degree-based entropy of molecular structure of HAC5C7[p,q]
Articles in Press, Accepted Manuscript, Available Online from 06 April 2021
Abstract
Graph entropy associated with the graph, first considered by K ̈orner [1]. Graph entropy has been used extensively to characterize the structure of graph-based systems in mathematical chemistry. In these applications the entropy of a graph is interpreted as its structural information content and serves ...
