  • Publication number: 20120045385
    Abstract: A system is provided that can be utilized to generate nanotubes with substantially similar chirality. The system provides a resonant frequency, keyed to a desired radial breathing mode linked to the desired chirality, that causes a template of catalysts particles or nanotubes to oscillate at the provided resonant frequency, so as to stimulate growing nanotubes to oscillate at a corresponding resonant frequency. This resonant frequency can be a result of a high frequency field or the natural heat radiation generated by the system.

  • Publication number: 20110316183
    Abstract: A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system include a housing coupled to a synthesis chamber within which nanotubes are produced. A spindle may extend from within the housing, across the inlet, and into the chamber for collecting nanotubes and twisting them into a yarn. A body portion may be positioned at an intake end of the spindle. The body portion may include a pathway for imparting a twisting force onto the flow of nanotubes and guide them into the spindle for collection and twisting into the nanofibrous yarn.

  • Publication number: 20110214850
    Abstract: A heat-conducting medium for placement between a heat source and heat sink to facilitate transfer of heat from the source to the sink is provided. The heat-conducting medium can include a disk having relatively high thermal conductivity and heat spreading characteristics. The heat-conducting medium also includes a first recessed surface and an opposing second recessed surface. Extending from within each recessed surface is an array of heat conducting bristles to provide a plurality of contact points to the heat source and heat sink to aid in the transfer of heat. The recessed surfaces may be defined by a rim positioned circumferentially about the disk. The presence of the rim about each recessed surface acts to minimize the amount of pressure that may be exerted by the heat sink and the heat source against the bristles. A method for manufacturing the heat-conducting medium is also provided.

  • Publication number: 20100324656
    Abstract: A method for manufacturing a carbon composite is provided. The method includes providing a carbon-containing resin material to which an appropriate concentration of catalyst particles may be added. Thereafter, the catalyzed resin may be subject to a high temperature range, at which point carbon in the resin to begins to couple to the catalyst particles. Continual exposure to high temperature leads to additional attachment of carbon to existing carbon on the particles. Subsequently growth, within the resin material, of an array of carbon nanotubes occurs, as well as the formation of the composite material.

A heating zone is situated downstream from the tube to provide a temperature range sufficient to permit the formation, from components within the fluid mixture, of catalyst particles upon which nanostructures can be generated. A mechanism is further provided at a distal end of the chamber to minimize turbulent flow as the fluid mixture exits the chamber, and to impart a substantially laminar flow thereto.
