    摘要： A method for sorting carbon nanotubes (CNTs) is disclosed. In one embodiment, a method for sorting CNTs of the present disclosure comprises providing to a surface of a substrate, the surface modified with a trans isomer of photo-isomerization-reactive diazo compound, a dispersion containing a mixture of conducting CNTs and semiconducting CNTs; removing CNTs which are not associated with the modified surface from the surface; and irradiating the modified surface to detach the CNTs associated with the modified surface.

    摘要： The present disclosure provides systems and methods for production of nanostructures using a plasma generator. In an embodiment, a system for use with a reactor for synthesis of nanostructures may include a chamber defining a pathway for directing a fluid mixture for the synthesis of nanostructures through the chamber. The system may further include one or more heating zones disposed along the chamber to provide a temperature gradient in the chamber to form catalyst particles upon which nanostructures can be generated from the components of the fluid mixture. The system may also include a plasma generator for generating a plasma flame in a conduit through which the fluid mixture may be passed to decompose a carbon source in the fluid mixture into its constituent atoms before proceeding into the reactor for formation of nanostructures.

    摘要： A nanotube separation method includes depositing a tag on a nanotube in a nanotube mixture. The nanotube has a defect and the tag deposits at the defect where a deposition rate is greater than on another nanotube in the mixture lacking the defect. The method includes removing the tagged nanotube from the mixture by using the tag. As one option, the tag may contain a ferromagnetic material and the removing may include applying a magnetic field. As another option, the tag may contain an ionic material and the removing may include applying an electric field. As a further option, the tag may contain an atom having an atomic mass greater than the atomic mass of carbon and the removing may include applying a centrifugal force to the nanotube mixture. Any two or more of the indicated removal techniques may be combined.
