Researchers from the Massachusetts Institute of Technology (MIT) in the U.S. report that they have developed a paper-like membrane constructed of potassium manganese oxide nanowires that can absorb 20 times its weight in oil and allows the oil to be recovered, potentially leading to a new solution for cleaning up oil spills and removing organic pollutants from water. Researcher Francesco Stellacci explained that the membrane can “selectively absorb hydrophobic liquids-oil-like liquids-from water.” Once used, the oil can be removed from the membrane through evaporation and re-condensed into liquid. The membrane and the oil can then be reused. Researcher Jing Kong said that membrane could also be used in water purification, adding that the material could potentially be inexpensive to produce. Stellacci explained that the membrane is produced through a similar process as papermaking. The article can be viewed online at the link below.
