  • Publication number: 20100051843
    Abstract: Precise control over gas delivery is achieved at the micro and nanobar mass levels by incorporating blocks of aligned carbon nanotubes into valves and finely adjusting the flow through the block by controlling a compressing force applied to the block. A valve for controlling gas flow includes: a valve housing; a block of aligned carbon nanotubes, the block and the valve housing being configured to direct the gas through the carbon nanotubes in the block; and a device configured to apply a force to the block in order to compress the block, wherein the block is compressed perpendicular to the walls of the carbon nanotubes in the block; whereby the application of the force to the walls restricts the flow of the gas through the valve. The valve may further comprise an electrical device for monitoring the electrical properties of the carbon nanotube block. This monitoring provides information on the state of compression of the carbon nanotube block and/or the gas that is flowing through the valve.

  • Publication number: 20080212261
    Abstract: Embodiments of the invention relate to energy storage devices, e.g., capacitors and batteries, that may include a composite article of elongated conductive structures embedded in a polymer matrix. In some embodiments, a liquid containing ionic species may be dispersed within the polymer matrix of the article. The liquid may contact the elongated conductive structures within the polymer matrix. When the composite article is used as an energy storage device, the large surface area at the interface between the elongated conductive structures and the liquid can provide high energy storage. Embodiments of the invention enable storing energy using a composite article that exhibits both high and low temperature stability, high cyclic repeatability, and mechanical flexibility. The composite article can also be non-toxic, biocompatible and environmentally friendly. Thus, the composite article may be useful for a variety of energy storage applications, such as in the automotive, RFID, MEMS and medical fields.

  • Patent number: 6852648
    Abstract: A process for fabricating an integrated semiconductor device with a low dielectric constant material and an integrated semiconductor device with the low dielectric constant material interposed between two conductors is disclosed. The low dielectric constant material has a dielectric constant of less than about 2.8. The low dielectric constant material is a porous glass material with an average pore size of less than about 10 nm. The low dielectric constant material is formed on a semiconductor substrate with circuit lines thereover by combining an uncured and unmodified glass resin with an amphiphilic block copolymer. The amphiphilic block copolymer is miscible in the uncured glass resin. The mixture is applied onto the semiconductor substrate and the glass resin is cured. The glass resin is further processed to decompose or otherwise remove residual block copolymer from the cured glass resin.
