Swelling Glass Cleans Polluted Water Like a Sponge

A new kind of glass can swell to absorb pollutants in water. This is the discovery that could put the College of Wooster on the map: glass that swells like a sponge. Put together like a nano-matrix, the new glass can unfold to hold up to eight times its weight. The glass binds with gasoline and other pollutants containing volatile organic compounds but it does not bind with water, so it acts like a smart sponge, capable of picking and choosing from contaminated groundwater
