TL;DR: In this paper, the usefulness of graph theoretical approach for modeling the electronic properties of zinc sulfide nanoclusters has been investigated and the main goal is to construct a tool to assist in the prediction of electronic properties for large size clusters without demanding computations.

TL;DR: In this article, a hybrid chemical flooding that contained the subsequent flooding of surfactant-polymer (SP) coupled with supercritical carbon dioxide was performed to enhance the oil recovery factor.

TL;DR: In this article, the optimum arrangement of a reverse osmosis system in two methods of plug and concentrate recycling was determined for Mahyarkala city, located in north of Iran, for a period of 20 years.
