| Abstract : |
The dynamic transport of fluids in nanochannels is receiving increased attention not only because of its relevance to fundamental questions regarding fluid behavior near or below the continuum limit, but also because of its potential implications in technological applications of the future. An investigation is presented on the dynamic characteristics of multiphase fluids in multiwall carbon nanotubes. Thermal experiments with nanonmeter resolution are conducted in the high vacuum of a transmission electron microscope using electron irradiation as a means of heating the fluid contents of individual nanotubes. Video sequences demonstrate the capability to transfer fluid along the carbon nanotube interior. Some aspects of wetting at fine scales are also discussed. This research demonstrates the potential of incorporating carbon nanotubes in future nanofluidic devices. |
