Fluidic and electrofluidic devices comprising carbon nanotubes and methods of making and using the same are provided. The carbon nanotubes may be densely bundled to span an aperture in a substrate. A polymeric coating over the substrate may contain reservoir(s) etched therein, the reservoir(s) in fluid connectivity with the carbon nanotubes. X-rays may be directed through the aperture and fluid-filled carbon nanotubes with x-ray analysis providing data on fluid structure and dynamics inside the carbon nanotubes.

Fluidic carbon nanotube device

A molecular dynamics system employing a spliced soft-core potential (the 'MD/SSCP') facilitates studying the arrangement of particles in an enclosure and/or near an interface. In some embodiments, the MD/SSCP initializes a three-dimensional representation containing the enclosure and the particles in a first arrangement. The MD/SSCP conducts a first simulation to transition the representation to a second arrangement, during which the particles are allowed to move through a wall of the enclosure while the SSCP is unengaged. The MD/SSCP conducts a second simulation to transition the representation to a third arrangement, during which it becomes more difficult for the particles to move through the wall of the enclosure while the SSCP is gradually engaged. The MD/SSCP conducts a third simulation to transition the representation to a fourth arrangement of the particles, during which it becomes almost impossible for the particles to move through the wall of the enclosure.

Spliced soft-core interaction potential for filling small-scale enclosures

A product includes a nanoporous membrane having a plurality of carbon nanotubes and a fill material in interstitial spaces between the carbon nanotubes for limiting or preventing fluidic transfer between opposite sides of the nanoporous membrane except through interiors of the carbon nanotubes. The longitudinal axes of the carbon nanotubes are substantially parallel, an average inner diameter of the carbon nanotubes is about 20 nanometers or less, and both ends of at least some of the carbon nanotubes are open. Moreover, the fill material is impermeable or having an average porosity that is less than the average inner diameter of the carbon nanotubes.
