| 20080311025 | METHOD FOR FORMING A PATTERNED ARRAY OF FULLERENE NANOTUBES - This invention relates generally to forming a patterned array of fullerene nanotubes. In one embodiment, a nanoscale array of microwells is provided on a substrate; a metal catalyst is deposited in each microwells; and a stream of hydrocarbon or CO feedstock gas is directed at the substrate under conditions that effect growth of fullerene nanotubes from each microwell. | 12-18-2008 |
| 20090004094 | METHOD FOR CUTTING FULLERENE NANOTUBES - 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. | 01-01-2009 |

| 20100096265 | MACROSCOPICALLY MANIPULABLE NANOSCALE DEVICES MADE FROM NANOTUBE ASSEMBLIES - This invention relates generally to cutting single-wall carbon nanotubes (SWNT). In one embodiment, the present invention provides for preparations of homogeneous populations of short carbon nanotube molecules 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 single-wall nanotubes. In one embodiment, oxidative etching with concentrated nitric acid is employed to cut SWNTs 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. | 04-22-2010 |
| 20100099815 | COUPLED CHARGE TRANSFER NANOTUBE DOPANTS - Stable charge-transfer doping of carbon nanotubes is achieved using a dopant containing polymer (DCP) wherein the DCP has a multiplicity of dopant moieties that are capable of donating electrons to or accepting electrons from the nanotubes linked to a polymer. The DCP has a sufficient number of dopant moieties connected to the polymer such that when charge transfer equilibrium between a particular dopant moiety and the nanotubes is in a dissociated, or dedoped state, the dopant moiety remains tethered by a linking moiety to the polymer and remains in the vicinity of the nanotubes as the polymer remains bound to the tube by at least one bound dopant of the DCP. The linking groups are selected to permit the presentation of the dopant moieties to the nanotubes in a manner that is unencumbered by the polymer backbone and can undergo charge transfer doping. | 04-22-2010 |
| 20100272981 | TRANSPARENT AND ELECTRICALLY CONDUCTIVE SINGLE WALL CARBON NANOTUBE FILMS - An optically transparent and electrically conductive single walled carbon nanotube (SWNT) film comprises a plurality of interpenetrated single walled carbon nanotubes, wherein for a 100 nm film the film has sufficient interpenetration to provide a 25° C. sheet resistance of less than 200 ohm/sq. The film also provides at least 20% optical transmission throughout a wavelength range from 0.4 μm to 5 μm. | 10-28-2010 |
