Abstract: "We report gas and water flow measurements
through microfabricated membranes in which aligned carbon nanotubes with
diameters of less than 2 nanometers serve as pores. The measured gas flow
exceeds predictions of the Knudsen diffusion model by more than an order of
magnitude. The measured water flow exceeds values calculated from continuum
hydrodynamics models by more than three orders of magnitude and is
comparable to flow rates extrapolated from molecular dynamics simulations.
The gas and water permeabilities of these nanotube-based membranes are
several orders of magnitude higher than those of commercial polycarbonate
membranes, despite having pore sizes an order of magnitude smaller. These
membranes enable fundamental studies of mass transport in confined
environments, as well as more energy-efficient nanoscale filtration."
