New smart coating could make oil-spill cleanup faster and more efficient

16-May-2014

In the wake of recent off-shore oil spills, and with the growing popularity of "fracking" — in which water is used to release oil and gas from shale — there's a need for easy, quick ways to separate oil and water. Now, scientists have developed coatings that can do just that. Their report on the ...
