Molecules pass through nanotubes at size-dependent speeds
Cambridge MA (SPX) Sep 18, 2013
Like a pea going through a straw, tiny molecules can pass through microscopic cylinders known as nanotubes. This could potentially be used to select molecules according to size - for example, to purify water by allowing water molecules to pass through while blocking salt or other substances. Now, researchers at MIT, Seoul University in Korea and Ursinus College in Pennsylvania have found that such tubes are more selective than had been thought: Molecules of a precise size can zip through five time ... read more
