Carbon nano tubes

Scientists are using carbon nanotubes as a filter to desalinate water


“We found that carbon nanotubes with diameters smaller than a nanometer bear a key structural feature that enables enhanced transport. The narrow hydrophobic channel forces water to translocate in a single-file arrangement, a phenomenon similar to that found in the most efficient biological water transporters,” said Ramya Tunuguntla, an LLNL postdoctoral researcher. The nanotube pores have been specifically sized to filter water molecules in a single file, effectively let through as much as possible while blocking the larger salt ions. This method means far faster desalination times. “You can imagine [
