Michigan Technological University scientists Yoke Khin Yap and Jaroslaw Drelich created the nano filter, whose fine, stainless steel mesh is coated with carbon nanotubes about 10 microns across. The research team poured an emulsion of water and gasoline over the prototype filter (about the size of a quarter) to test it. The gas dripped through, and all but 20 percent of the water stayed put. The research was funded by the NSF.
