Green Walls as an Approach in Grey Water Treatment

An integrated green supplier selection approach with analytic network process and improved Grey relational analysis

With increased worldwide awareness of environmental protection, green supply chain management (GSCM) has received much attention from both researchers and practitioners over the past decade. Traditionally, organizations have considered criteria such as cost, quality, and delivery to evaluate the performance of their suppliers. Although there is an abundance of studies considering the convention...

An Improved Hybrid Grey Relational Analysis Approach for Green Resilient Supply Chain Network Assessment

In the growing and turbulent market of the current world both in national and in international relations, the need for reviewing and assessment of the resiliency of suppliers as one of the new concepts in supply chain management has been prioritized. In addition, globalization, increasing the regulations of governmental and non-governmental organizations, customers’ request and pressure regardi...

Phthalates as Emerging Pollutants in Water Environment: Control & Treatment Strategies

A green approach for the synthesis of 2-amino-4H-chromene derivatives using Polystyrene-Supported 1-Methylimidazolium tetrachloroferrate as an efficient heterogeneous catalyst in water

In this study, we reported facile and efficient synthesis of 2-amino-4H-chromenes that catalyzed by polystyrene-supported 1-methylimidazolium tetrachloroferrateas. The synthesis proceeds with various aldehydes under mild conditions and afford the target products with good to high yields.

An Efficient Green Approach for the Synthesis of Fluoroquinolones Using Nano Zirconia Sulfuric Acid as Highly Efficient Recyclable Catalyst in two Forms of Water

Various antibacterial fluoroquinolone compounds were prepared by the direct amination of 7-halo-6- fluoroquinolone-3-carboxylic acids with a variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine using Zirconia Sulfuric Acid (ZrSA) nanoparticle, as a catalyst in the presence of ordinary or magnetized water upon reflux condition. The results showed that ZrSA exh...
