It is a silent change which has been occurring over the past one decade. The schemes launched to reverse the process of infamous ‘brain drain’ have finally started yielding results. The number of young scientists returning to do scientific research in India and taking up positions in research and academic institutions is steadily rising. The quality of research output of these returnees is also very high.
Scientists are trying to exploit this property for developing novel materials that can find application in addressing oil pollution. The objective is to synthesize artificial interfaces that have oil repelling property or underwater superoleophobicity.
In this direction, a group of researchers at the Indian Institute of Technology (IIT), Guwahati, have developed a stretchable underwater superoleophobic membrane that can separate water from various forms of oil-contaminations.
