Ejection dynamics of a simple liquid from individual carbon nanotube nozzles

Molecular dynamics simulations show that the flow of a high pressurized atomic liquid inside carbon nanotube pipets occurs in one-atom-thick well-defined laminae. Fluxes and velocities at ejection are a function of the inlet diameter and the type of outlet. In the conditions investigated here, the force of the ejected liquid is similar in value to that of biomotors, while the output per second is of the order of picoliters.
