Abstract: This invention is directed to chemical derivatives of carbon nanotubes wherein the carbon nanotubes have a diameter up to 3 nm. In one embodiment, this invention also provides a method for preparing carbon nanotubes having substituents attached to the side wall of the nanotube by reacting single-wall carbon nanotubes with fluorine gas and recovering fluorine derivatized carbon nanotubes, then reacting fluorine derivatized carbon nanotubes with a nucleophile. Some of the fluorine substituents are replaced by nucleophilic substitution. If desired, the remaining fluorine can be completely or partially eliminated to produce carbon nanotubes having substituents attached to the side wall of the nanotube. The substituents are dependent on the nucleophile, and preferred nucleophiles include alkyl lithium species such as methyl lithium.

Abstract: Cryogenic fluids are used to remove contaminants such as hard scale deposits from heating and/or heat transfer equipment. The fluid may be cryogenically cooled to achieve a liquid phase and/or a mixture of liquid and gas phases. The fluid may also be pressurized. The mixture does not include a solid phase. A particle injection port is not required. The cryogenic fluid contacting the surface of a scale or other contaminant that has built-up during service of heating or heat exchanging equipment causes a near instantaneous contraction at the scale surface. Cracks form at the scale surface contacted by the cryogenic fluid. These cracks extend through the scale thickness to the underlying material of the equipment of the heating and/or heat exchanging component. The fractured surface scale separates by spalling or de-cohesion from the underlying equipment structure and is moved off the surface by the action of the exiting cryogenic fluid.

Abstract: This invention is directed to making chemical derivatives of carbon nanotubes and to uses for the derivatized nanotubes, including making arrays as a basis for synthesis of carbon fibers. In one embodiment, this invention also provides a method for preparing single wall carbon nanotubes having substituents attached to the side wall of the nanotube by reacting single wall carbon nanotubes with fluorine gas and recovering fluorine derivatized carbon nanotubes, then reacting fluorine derivatized carbon nanotubes with a nucleophile. Some of the fluorine substituents are replaced by nucleophilic substitution. If desired, the remaining fluorine can be completely or partially eliminated to produce single wall carbon nanotubes having substituents attached to the side wall of the nanotube. The substituents will, of course, be dependent on the nucleophile, and preferred nucleophiles include alkyl lithium species such as methyl lithium.

Abstract: This invention relates generally to cutting fullerene nanotubes. In one embodiment, the present invention provides for preparation of homogeneous populations of short fullerene nanotubes by cutting and annealing (reclosing) the nanotube pieces followed by fractionation. The cutting and annealing processes may be carried out on a purified nanotube bucky paper, on felts prior to purification of nanotubes or on any material that contains fullerene nanotubes. In one embodiment, oxidative etching with concentrated nitric acid is employed to cut fullerene nanotubes into shorter lengths. The annealed nanotubes may be disbursed in an aqueous detergent solution or an organic solvent for the fractionation. Closed tubes can also be derivatized to facilitate fractionation, for example, by adding solubilizing moieties to the end caps.

Abstract: The present invention is directed to the creation of macroscopic materials and objects comprising aligned nanotube segments. The invention entails aligning single-wall carbon nanotube (SWNT) segments that are suspended in a fluid medium and then removing the aligned segments from suspension in a way that macroscopic, ordered assemblies of SWNT are formed. The invention is further directed to controlling the natural proclivity or nanotube segments to self assemble into or ordered structures by modifying the environment of the nanotubes and the history of that environment prior to and during the process. The materials and objects are “macroscopic” in that they are large enough to be seen without the aid of a microscope or of the dimensions of such objects.

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 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.
