Nanoscale hydrodynamics: Enhanced flow in carbon nanotubes

Mainak Majumder1, Nitin Chopra1, Rodney Andrews2 & Bruce J. Hinds1

Nanoscale structures that could mimic the selective transport and extraordinarily fast flow possible in biological cellular channels would have a wide range of potential applications. Here we show that liquid flow through a membrane composed of an array of aligned carbon nanotubes is four to five orders of magnitude faster than would be predicted from conventional fluid-flow theory. This high fluid velocity results from an almost frictionless interface at the carbon-nanotube wall.
