Oil spill cleanup with nanomesh "paper towels"

"Paper towel" can clean up oil spills

Researchers at MIT have combined a nanowire mesh with a water-repellant coating that can absorb up to 20 times its weight in oil. The oil absorbed can be recovered and the "paper towel" can be reused many times.

"Made of potassium manganese oxide, the nanowires are stable at high temperatures. As a result, oil within a loaded membrane can be removed by heating above the boiling point of oil. The oil evaporates, and can be condensed back into a liquid. The membrane--and oil--can be used again." MIT News
