Cleaning Oil Spills

~200,000 tons of oil have polluted waters around the world from 2000=2010 alone. In response, researchers have designed nanowires of potassium manganese oxide that feels like paper. Tiny pores between the wires absorb oil (up to 20 times its weight) but repel water. It can also be reused because potassium manganese oxide is stable at high temperatures. This means one simply heats the nanowires above oil's boiling point so the oil evaporates while the paper is clean ... and the oceans
