Oil spill removal from water. (a) Paraffin oil (colored for clarity)

Download scientific diagram | Oil spill removal from water. (a) Paraffin oil (colored for clarity) floating on water; (b) the oil being absorbed into the aerogel; and (c) all of the floating oil has been absorbed. (d) The oil-filled aerogel can be washed simply by immersing it in a solvent, such as ethanol. The oil gets removed as shown by the red streaks.
