The researchers from the Indian Institute of Technology (IIT) Guwahati, Assam invented two distinct and special membranes that can separate oil and water, even under harsh conditions. This development is expected to be used in applications of oil spill management. The work is published in ACS Sustainable Chemistry & Engineering journal. The membranes are super-water repellent in air and super oil-repellent in water. The research was led byUttam Manna, Assistant prof. at Department of Chemistry, IIT Guwahati along with his research team Avijit Das, Dibyangana Parbat and Arpita Shome.
