Lawrence Livermore scientists, in collaboration with Northeastern University have developed a saltwater purification device. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm) exceeds that of wider CNTs by an order of magnitude. The nanotubes, hollow structures made of carbon atoms in a unique arrangement, are more than 50,000 times thinner than a human hair...
