Abstract: Field emission nanostructures assist operation of a microdischarge device. The field emission nanostructures are integrated into the microdischarge device(s) or are situated near an electrode of the microdischarge device(s). The field emission nanostructures reduce operating and ignition voltages compared to otherwise identical devices lacking the field emission nanostructures, while also increasing the radiative output of the microdischarge device(s).

Abstract: An apparatus comprises a scanning electron microscope (SEM) (1) positioned over a manipulation chamber (2) which houses a sample holder (3). The walls of the manipulation chamber (2) support two probes (4, 4a) and the sample holder (3) is able to hold a sample (5), such as carbon nanotubes (10a) carried on a substrate (10). The apparatus can selectively move and apply voltages and currents to the probe or probes (4, 4a) and sample holder (3) under the SEM (1). By controlling the current that is passed across a contact between the probe (4) and a carbon nanotube (10a), a conditioned weld is formed. Likewise, by controlling the current that is passed along a carbon nanotube (10a), the nanotube (10a) can be annealed. Using both the probes (4, 4a) a carbon nanotube can be held and cut at any position along its length. This allows the formation of novel carbon nanotube structures.

Abstract: This invention relates generally to cutting single-wall carbon nanotubes (SWNT). In one embodiment, the present invention provides for preparations of homogemeous 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.
