The invention relates to a chemical vapor deposition process for the continuous growth of a carbon single-wall nanotube where a carbon-containing gas composition is contacted with a porous membrane and decomposed in the presence of a catalyst to grow single-wall carbon nanotube material. A pressure differential exists across the porous membrane such that the pressure on one side of the membrane is less than that on the other side of the membrane. The single-wall carbon nanotube growth may occur predominately on the low-pressure side of the membrane or, in a different embodiment of the invention, may occur predominately in between the catalyst and the membrane. The invention also relates to an apparatus used with the carbon vapor deposition process.

A carbon nanotube heat-exchange system () and method for producing the same. One embodiment of the carbon nanotube heat-exchange system () comprises a microchannel structure () having an inlet end () and an outlet end (), the inlet end () providing a cooling fluid into the microchannel structure () and the outlet end () discharging the cooling fluid from the microchannel structure (). At least one flow path () is defined in the microchannel structure (), fluidically connecting the inlet end () to the outlet end () of the microchannel structure (). A carbon nanotube structure () is provided in thermal contact with the microchannel structure (), the carbon nanotube structure () receiving heat from the cooling fluid in the microchannel structure () and dissipating the heat into an external medium ().

The present invention discloses a carbon nanotube (SWNT)-polymer composite actuator and method to make such actuator. A series of uniform composites was prepared by dispersing purified single wall nanotubes with varying weight percents into a polymer matrix, followed by solution casting. The resulting nanotube-polymer composite was then successfully used to form a nanotube polymer actuator.

Metal-doped single-walled carbon nanotubes and production thereof. The metal-doped single-walled carbon nanotubes may be produced according to one embodiment of the invention by combining single-walled carbon nanotube precursor material and metal in a solution, and mixing the solution to incorporate at least a portion of the metal with the single-walled carbon nanotube precursor material. Other embodiments may comprise sputter deposition, evaporation, and other mixing techniques.
