Abstract: This invention relates generally to a method for producing self-assembled objects comprising fullerene nanotubes and compositions thereof. In one embodiment, the present invention involves a three-dimensional structure of derivatized fullerene nanotubes that spontaneously form. It includes several components having multiple derivatives brought together to assemble into the three-dimensional structure. In another embodiment, objects may be obtained by bonding functionally-specific agents (FSAs) to groups of nanotubes, enabling them to form into structures. The bond selectivity of FSAs allow selected nanotubes of a particular size or kind to assemble together and inhibit the assembling of unselected nanotubes that may also be present.

Abstract: This invention relates generally to a method for producing fullerene nanotube catalyst supports and compositions thereof. In one embodiment, fullerene nanotubes or fullerene nanotube structures can be employed as the support material. A transition metal catalyst is added to the fullerene nanotubes. In a preferred embodiment, the catalyst metal cluster is deposited on the open nanotube end by a docking process that insures optimum location for the subsequent growth reaction. The metal atoms may be subjected to reductive conditions.

Abstract: This invention relates generally to a fullerene nanotube composition. The fullerene nanotubes may be in the form of a felt, such as a bucky paper. Optionally, the fullerene nanotubes may be derivatized with one or more functional groups. Devices employing the fullerene nanotubes of this invention are also disclosed.

Abstract: The invention relates generally to dispersing and fractionating single-wall carbon nanotubes, which can be derivatized to facilitate fractionation, for example, by adding solubilizing moieties to the nanotubes.

Abstract: This invention relates generally to a fullerene nanotube purification process and more particularly to a purification process that comprises heating the fullerene nanotube-containing felt under oxidizing conditions to remove the amorphous carbon deposits and other contaminating materials. In a preferred mode of this purification procedure, the felt is heated in an aqueous solution of an inorganic oxidant, such as nitric acid, a mixture of hydrogen peroxide and sulfuric acid, or a potassium permanganate. Preferably, fullerene nanotube-containing felts are refluxed in an aqueous solution of an oxidizing acid at a concentration high enough to etch away amorphous carbon deposits within a practical time frame, but not so high that the fullerene nanotube material will be etched to a significant degree. When material having a high proportion of fullerene nanotubes is purified, the preparation produced will be enriched in fullerene nanotubes, so that the fullerene nanotubes are substantially free of other material.

Abstract: This invention provides a method of making single-wall carbon nanotubes by laser vaporizing a mixture of carbon and one or more Group VIII transition metals. Single-wall carbon nanotubes preferentially form in the vapor and the one or more Group VIII transition metals catalyzed growth of the single-wall carbon nanotubes. In one embodiment of the invention, one or more single-wall carbon nanotubes are fixed in a high temperature zone so that the one or more Group VIII transition metals catalyze further growth of the single-wall carbon nanotube that is maintained in the high temperature zone. In another embodiment, two separate laser pulses are utilized with the second pulse timed to be absorbed by the vapor created by the first pulse.

Abstract: This invention relates generally to membranes comprising an array of single-wall carbon nanotubes (SWNT) wherein the membrane is nanoporous. In one embodiment, the membrane comprises a substantially two-dimensional array of a homogeneous population of single-walled nanotubes aggregated in substantially parallel orientation to form a monolayer extending in directions substantially perpendicular to the orientation of the individual nanotubes. Using single-wall carbon nanotubes of the same type and structure provides a homogeneous array. By using different single-wall carbon nanotubes, either a random or ordered heterogeneous structure can be produced by employing successive reactions after removal of previously masked areas of a substrate.
