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.

Abstract: A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system is coupled to a chamber that generates nanomaterials, typically carbon nanotubes produced from chemical vapor deposition, and includes a mechanism for spinning the nanotubes into yarns or tows. Alternatively, the system includes a mechanism for forming non-woven sheets from the nanotubes. The system also includes components for collecting the formed nanofibrous materials. Methods for forming and collecting the nanofibrous materials are also provided.

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 flexible member made from an array of interweaving carbon nanotubes. The heat-conducting medium may also include an upper surface against which a heat source may be placed, an opposing lower surface and edges about the member designed for coupling to a heat sink toward which heat from the heat source can be directed. The heat-conducting medium may also include a pad placed on the upper surface to provide structural support to the member. A method for manufacturing the heat-conducting medium is also provided.

Abstract: An antenna for the transmission and reception of electromagnetic radiation is provided. The antenna includes a body portion, which can be flexible to permit incorporation of the antenna into a material. The antenna also includes an aggregate of extended length nanotubes along the body portion, and a plurality of contact points between adjacent nanotubes to permit transmission of electromagnetic radiation, while reducing resistivity along the antenna at a high frequency, for example, above 100 MHz. A method of manufacturing an antenna is also provided.

Abstract: A system for synthesizing nanostructures using chemical vapor deposition (CVD) is provided. The system includes a housing, a porous substrate within the housing, and on a downstream surface of the substrate, a plurality of catalyst particles from which nanostructures can be synthesized upon interaction with a reaction gas moving through the porous substrate. Electrodes may be provided to generate an electric field to support the nanostructures during growth. A method for synthesizing extended length nanostructures is also provided. The nanostructures are useful as heat conductors, heat sinks, windings for electric motors, solenoid, transformers, for making fabric, protective armor, as well as other applications.
