Hierarchical Membrane For Cleaning Up Oil Spills 32

rtoz (2530056) writes Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an "emulsion." It is extremely hard to separate them, and they can cause severe damage to ecosystems. Now, MIT researchers have discovered a new, inexpensive way of getting the two fluids apart again. This new approach uses membranes with hierarchical pore structures. The membranes combine a very thin layer of nanopores with a thicker layer of micropores to limit the passage of unwanted material while providing strength sufficient to withstand high pressure and throughput.

    BP got in big trouble for an internal memo that discussed the idea of reclaiming the oil. It was a "how dare they think of protecting their assets after doing this" outrage.

    I don't have a strong opinion about that memo or the outrage(even though I'm quite concerned with environmental matters on principle). Just that that happened.
