Abstract:
In molecular dynamics simulations we found that water can form hydrogen-bonded water chains in the interior of carbon nanotubes. Water penetration is sensitive to details of thermodynamic conditions and interaction potentials, resulting in sharp, first-order like transitions between filled and empty states. Under wetting conditions, water molecules are transported e±ciently through nanotubes. Implications on the design of nanotube channels for small molecules and protons will be discussed.
