November 4 – The material can absorb oil repeatedly at least 100 times – Removing up to 95% of oil-spill of different densities — light and heavy oils — repetitively at least 100 times using superhydrophobic (extremely water repelling) medical cotton has been demonstrated by a team of researchers led by Dr. Uttam Manna from the Department of Chemistry at the Indian Institute of Technology (IIT) Guwahati.
In the picture: “The efficiency of absorption is very high – above 2,000 weight percentage for both heavy and light oils,” say Uttam Manna (left) and Adil Majeed Rather
