    摘要： The present teachings are directed to methods of preparing cylindrical carbon structures, specifically single-walled carbon nanotubes, with a desired chirality. The methods include the steps of providing a catalyst component on a substrate and a carbon component, contacting the catalyst component and the carbon component to produce a cylindrical carbon structure. Then, no longer providing the carbon component and determining the chirality of the cylindrical carbon structure. The catalyst component is then cleaned and the process is repeated until the cylindrical carbon structure fulfills a desired characteristic, such as, length. The chirality of the single-walled carbon nanotube grown, after cleaning of the catalyst component, has the same chirality as the initially produced nanotube.

    摘要： Carbon nanotubes are formed by chemical vapor deposition using metal nanoparticles as a growth substrate. Control over the size and properties of the carbon nanotubes is achieved by controlling the size of the metal nanoparticles in the growth substrate. The metal nanoparticles of a controlled size may be formed by a thermal decomposition reaction of a metal salt in a passivating solvent.

    摘要： Methods, processes, and apparatuses for the large scale synthesis of carbon nanostructures are provided. Metal catalysts having small diameter and narrow distribution of particle sizes are prepared and continuously injected as aerosols into a reactor. The metal catalysts are supported on supports that are substantially free of carbon. The metal catalyst, in the form of a powder, is placed in an injector that is shaken vertically. The powder is aerosolized, and the powder entrailed in the gas is passed through a conduit that is bifurcated where one portion delivers the powder to the reactor while the other portion connects back to the ejector that is located in between the gas source and the top part of the container.

    摘要： Methods and processes for quantitating the carbon single-walled nanotubes (SWNTs) content in a sample are disclosed. The SWNTs soot can be produced by any of the known methods. The magic angle spinning (MAS) 13C NMR of a sample suspected of containing SWNTs and a standard at a known concentration are obtained, and the areas under the curve for the sample and the standard are calculated. Thereby, the concentration of 13C atoms involved in the formation of carbon SWNTs are calculated. Finally, by taking into account the natural distribution of 13C isotopes (about 1.1%), the total concentration of all carbon atoms responsible for the formation of SWNTs are calculated.
