  • Patent number: 7786466
    Abstract: Gate electrodes are formed on a semiconducting carbon nanotube, followed by deposition and patterning of a hole-inducing material layer and an electron inducing material layer on the carbon nanotube according to the pattern of a one dimensional circuit layout. Electrical isolation may be provided by cutting a portion of the carbon nanotube, forming a reverse biased junction of a hole-induced region and an electron-induced region of the carbon nanotube, or electrically biasing a region through a dielectric layer between two device regions of the carbon nanotube. The carbon nanotubes may be arranged such that hole-inducing material layer and electron-inducing material layer may be assigned to each carbon nanotube to form periodic structures such as a static random access memory (SRAM) array.

  • Publication number: 20100184669
    Abstract: The present invention is a method for detecting and destroying cancer tumors. The method is based on the concept of associating a linking protein or linking peptide such as, but not limited to, annexin V or other annexins to carbon nanotubes such as single-walled carbon nanotubes (SWNTs) to form a protein-CNT complex. Said linking protein or peptide can selectively bind to cancerous cells, especially tumor vasculature endothelial cells, rather than to healthy ones by binding to cancer-specific external receptors such as anionic phospholipids including phosphatidylserine expressed on the outer surfaces of cancer cells only. Irradiation of bound CNTs with one or more specific electromagnetic wavelengths is then used to detect and destroy those cells to which the CNTs are bound via the linking protein or peptide thereby destroying the tumor or cancer cells and preferably an immunostimulant is provided to the patient to enhance the immune response against antigens released from the tumor or cancer cells.

    Abstract: A Li-ion battery cell is formed from deposited thin-film layers and comprises a high-surface-area 3-D battery structure. The high-surface-area 3-D battery structure includes a fullerene-hybrid material deposited onto a surface of a conductive substrate and a conformal metallic layer deposited onto the fullerene-hybrid material. The fullerene-hybrid material is made up of chains of fullerene “onions” linked by carbon nanotubes to form a high-surface-area layer on the conductive substrate and has a “three-dimensional” surface. The conformal metallic layer acts as the active anode material in the Li-ion battery and also has a high surface area, thereby forming a high-surface-area anode. The Li-ion battery cell also includes an ionic electrolyte-separator layer, an active cathodic material layer, and a metal current collector for the cathode, each of which is deposited as a conformal thin film.

  • Publication number: 20100136343
    Abstract: Disclosed are a composite composition comprising carbon nanotubes and a transparent conductive film using the composite composition. The composite composition comprises a solution of an ion conductive polymeric binder in a solvent and carbon nanotubes dispersed in the solution. The transparent conductive film is formed by coating a dispersion of carbon nanotubes in an ion conductive polymeric binder on a base film to allow the transparent conductive film to be electrically conductive as a whole. The composite composition can be used to form a transparent conductive film with excellent bending properties as well as high electrical conductivity and high transparency. Therefore, the composite composition can be applied to transparent electrodes for use in foldable flat panel displays.
