  • Publication number: 20060021510
    Abstract: A method and apparatus for the production of hydrogen from carbon nanotubes saturated with hydrocarbon gas or greenhouse gas is described. The hydrogen that is produced is substantially free from carbon dioxide. Additionally, the method described is useful for converting the carbon elements of the hydrocarbon gas or greenhouse gas into a de novo synthesis of carbon nanotubes.

  • Publication number: 20050175885
    Abstract: What is disclosed is a process and apparatus for subjecting carbon nanotubes (100), to EM radiation for certain predetermined amounts of time. The result of said process and apparatus is heat release, light emission and gas evolution, accompanied by intense mechanical motion and carbon nanotube reconstruction.

  • Publication number: 20050139780
    Abstract: A practical method and apparatus for implanting elements, such as hydrogen, argon and krypton, and other compositions in a nanotube structure is disclosed. More specifically, such invention comprises, in one embodiment, an ion beam line apparatus used in conjunction with the requisite ancillary equipment necessary to accurately control the energy of an accelerated beam of hydrogen toward a nanostructured material.

  • Publication number: 20050118092
    Abstract: An apparatus and process for fabricating carbon nanotubes (“CNTs”) with specific diameters and morphologies, comprising a vacuum system, CNT holder and microwave source adapted for directing a microwave field onto the CNTs. The morphology selection can yield samples of pre-selected diameter configurations making it possible to take a sample of SWNTs produced by any synthesis technique and induce a morphology change that causes the sample to be either all conductive, all narrow band gap semi-conductive or wide band gap semi-conductive, within a given nanotube rope.

  • Publication number: 20050007001
    Abstract: The present invention provides a process and apparatus to store and deliver controlled amounts of heat and light energy, from low levels to very intense levels, to microscopic locations in a object remotely, not necessarily involving direct contact with the object, where the energy delivered remotely is less than the energy released by the object. More specifically, the present invention comprises a novel and previously unanticipated source of local energy production by the exposure of carbon nanotubes by EM radiation in the radio and microwave spectral regions. The present invention comprising a process and apparatus to remotely delivering highly controlled amounts of EM to the carbon nanotubes.

  • Publication number: 20040222081
    Abstract: The present invention is directed toward methods of crosslinking carbon nanotubes to each other using microwave radiation, articles of manufacture produced by such methods, compositions produced by such methods, and applications for such compositions and articles of manufacture. The present invention is also directed toward methods of radiatively modifying composites and/or blends comprising carbon nanotubes with microwaves, and to the compositions produced by such methods. In some embodiments, the modification comprises a crosslinking process, wherein the carbon nanotubes serve as a conduit for thermally and photolytically crosslinking the host matrix with microwave radiation.
