Surface-mediated liquid transport through molecularly thin liquid films on nanotubes.
We studied surface-mediated liquid transport through molecularly thin films on individual nanotubes in ambient conditions. The surface fluid with molecular thickness (approximately 10 A) flowed at a constant speed (approximately 10 microm/s) and volume flow rate (approximately 10 al/s) along the nanotubes. The volume flow rate Q follows the power law dependence Q approximately d2.4 on the nanotube diameter d, which is explained with a generic microscopic model.
