A method of modifying a carbon material is disclosed. The method comprises: bonding a metal to a carbon material to form a metal-carbon complex comprising the metal and a benzene unit, wherein the carbon material comprises extended sp-bonded carbon atoms.

Organometallic chemistry of extended periodic II-electron systems

Embodiments of the present disclosure present systems and methods for the synthesis of carbon nanotubes (CNTs) functionalized with mono-terminated, protected polyethylene glycol (PEG). As compared with bi-functional PEG, mono-terminated PEG the PEG-THFF oligomer has only one reaction site. The use of mono-terminated PEG may enhance the solubility of CNTs functionalized with mono-terminated PEG by inhibiting cross-linking between nanotubes and leads to a dramatic increase in aqueous solubility. In an example, single-walled carbon nanotubes functionalized with PEG having a tetrahydrofurfuryl (THFF) terminal group (SWNT-PEG-THFF) is found to disperse in water by ultrasonication and forms stable viscous dispersions at concentrations as high as about 9 g/L. This result exceeds the solubility of a previously reported SWNT-PEG graft copolymer, approximately 6 g/L, by more than 30%.

Water soluble carbon nanotubes

Systems and methods for the extraction of carbon nanotubes (CNTs) by continuous and/or batch processing are disclosed. Generally, a carbon nanotube material including carbon nanotubes (CNTs), carbon nanoparticles (CNPs), and carboxylated carbon (CC) is provided and agitated to produce a well-dispersed mixture. The well-dispersed mixture can be allowed to stand in a vessel having a lower end and an upper end. In some cases, the CNPs settle at the lower end. In some cases, at least some of the CNTs and CC are disposed at the upper end and can be removed in a dispersion, which can be pH adjusted and/or filtered to extract the CNTs from the CC.

Continuous extraction technique for the purification of carbon nanomaterials

Systems and methods for the purification of carbon nanotubes (CNTs) by continuous liquid extraction are disclosed. Carbon nanotubes are introduced to a flow of liquid that enables the separation of CNTs from impurities due to differences in the dispersibility of the CNTs and the impurities within the liquid. Examples of such impurities may include amorphous carbon, graphitic nanoparticles, and metal containing nanoparticles. The continuous extraction process may be performed in one or more stages, where one or more of extraction parameters may be varied between the stages of the continuous extraction process in order to effect removal of selected impurities from the CNTs. The extraction parameters may include, but are not limited to, the extraction liquid, the flow rate of the extraction liquid, the agitation of the liquid, and the pH of the liquid, and may be varied, depending on the impurity to be removed from the CNTs.

Magnetic Force Microscopy (MFM) probe tips that provide enhanced spatial resolution and methods of manufacture are provided. In one aspect, two or more magnetically-decoupled layers may be deposited on an AFM probe in order to create an active magnetic region at about the apex of the probe tip with dimensions less than about 10 nanometers. In another aspect, nanoscale patterning techniques may be employed to fabricate probe tips that possess plateau features. These plateau features may serve as substrates for the deposition of magnetic films having properties similar to magnetic recording media. Machining techniques, such as Focused Ion Beam (FIB) may be further employed to reduce the size of the magnetic materials deposited upon the substrate. Beneficially, because the plateaus of the substrate are substantially flat and of known geometry, and the magnetic properties of magnetic films deposited on flat surfaces are similar to those deposited upon the plateau, the magnetization of the MFM probe tips may be determined to high accuracy. In this manner, fine control over the magnetic properties of MFM probe tips may be achieved, providing enhanced MFM resolution.

Systems and methods for the preparation of reinforcements for composite materials, whereby single- and/or multi-walled carbon nanotubes (CNTs) may be electrophoretically deposited on fibrous substrates for the production of hybrid CNT/fibers. The fibers may include carbon fibers and woven carbon fabrics. The length, as well as the density and orientation of the deposited nanotubes on the fiber surfaces may also be tailored. The strength of the CNT/fiber-matrix interface formed in composites fabricated from the hybrid CNT/fibers may be adjusted by introduction of functional groups on the CNT/fiber surfaces, such as aminophenyl and carboxyphenyl groups.

Multiscale carbon nanotube-fiber reinforcements for composites

Systems and methods for designing and fabricating carbon nanotube based detectors are disclosed. In some embodiments, one or more sensor elements can be formed from a film of single-walled carbon nanotubes (SWNTs). Bolometric properties of such detectors are disclosed. In some embodiments, the film can be thermally isolated in various ways, such as suspending the film and providing a vacuum environment, to provide the bolometric properties. Various properties of the SWNT films, such as resistivity-dependence on temperature and spectral response, can be obtained by adjusting the dimension and/or composition of the film. Examples of SWNT film formation, detector element fabrication, and array fabrication are disclosed.

Method of solubilizing carbon nanotubes in organic solutions

An improved multilayer light emitting device includes novel compounds for use as the electron transporting layer. In particular, the novel compounds are novel aluminum cheltates (e.g. tris(9-oxidophenalenone) aluminum &lsqb;Al(9-opo) &rsqb; and tris(6-oxidobenzanthrone) aluminum &lsqb;Al(6-obao) &rsqb;. These compounds are electron acceptors having improved thermal stability while in most cases and in most applications maintaining comparable efficiencies. When negatively biased, electrons are infected into the electron transporting layer. The concurrent positive bias on the anode in relation to the cathode causes holes to be injected from the cathode into the hole transporting layer. Electroluminescence is produced and confined generally near the interface between these electron and hole transporting layers an a result of the recombination of the electron and hole pairs.
