  • Publication number: 20090050058
    Abstract: A method and apparatus for the unusually high rate deposition of thin film materials on a stationary or continuous substrate. The method includes the in situ generation of a neutral-enriched deposition medium that is conducive to the formation of thin film materials having a low intrinsic defect concentration at any speed. In one embodiment, the deposition medium is created by forming a plasma from an energy transferring gas; combining the plasma with a precursor gas to form a set of activated species that include ions, ion-radicals, and neutrals; and selectively excluding the species that promote the formation of defects to form the deposition medium. In another embodiment, the deposition medium is created by mixing an energy transferring gas and a precursor gas, forming a plasma from the mixture to form a set of activated species, and selectively excluding the species that promote the formation of defects.

  • Patent number: 7491448
    Abstract: A nano-particulate reticulated foam-like structure, which includes particles having a size of 10-200 nanometers. The particles are joined together to form a reticulated foam-like structure. The reticulated foam-like structure is similar to the structure of carbon nano-foam. The nano-particulate reticulated foam-like structure may comprise a metal, such as a hydrogen storage ahoy, either a gas-phase thermal or an electrochemical hydrogen storage alloy. The nano-particulate reticulated foam-like structure may alternatively comprise a hydroxide such as nickel hydroxide or manganese hydroxide or an oxide, such as a silver oxide or a copper oxide. When the nano-particulate reticulated foam-like structure is a hydrogen storage alloy, the material exhibits substantial immunity to hydrogen cycling decrepitation and an increase in the reversible hydrogen storage capacity by reduction of trapped hydrogen by at least 10% as compared to the same alloy in bulk form.

  • Patent number: 7440990
    Abstract: A method of factoring numbers in a non-binary computation scheme and more particularly, a method of factoring numbers utilizing a digital multistate phase change material. The method includes providing energy in an amount characteristic of the number to be factored to a phase change material programmed according to a potential factor of the number. The programming strategy provides for the setting of the phase change material once for each time a multiple of a potential factor is present in the number to be factored. By counting the number of multiples and assessing the state of the phase change material upon execution of the method, a determination of whether a potential factor is indeed a factor may be made. A given volume of phase change material may be reprogrammed for different factors or separate volumes of phase change material may be employed for different factors.

  • Patent number: 7393500
    Abstract: Electrochemical and gas phase hydrogen storage alloy compositions that provide superior performance, especially at low temperature, and excellent cycle life characteristics. The alloys of this invention are AB5 type alloys that include a cycle life enhancement element and a low Co concentration. The preferred cycle life enhancement elements include Zr and Si. The cycle life enhancement elements increase the cycle life of the instant alloys by reducing the pulverization of alloy particles upon repeated cycles of charging-discharging or hydriding-dehydriding. The alloys are characterized by low hysteresis on cycling, where hysteresis is measured in terms of mass concentration difference, a parameter related to the activation energy associated with the incorporation of hydrogen into the alloy. The instant alloys are designed to have a low activation energy for hydrogen incorporation and as a result, provide low hysteresis and a more uniform concentration of absorbed hydrogen within the material.

  • Patent number: 7388825
    Abstract: An optical data storage and retrieval system that includes a phase change storage medium and dual energy sources. The phase change material may store information by undergoing a transformation from one structural state to another structural state through application of energy. The system is equipped with two energy sources, neither of which alone provides sufficient energy to effect the transformation. The combination of both energy sources, however, provides sufficient energy to induce the transformation needed to record information. The energy from either source may be optical, thermal, electromagnetic, mechanical or magnetic energy.

  • Publication number: 20080090022
    Abstract: An apparatus and a method for high rate deposition of thin film materials. The method including the steps of (1) generating a supply of activated species from an energy transferring gas, through the use of a plasma; (2) separating the charged species from the non-charged species of the activated species (optionally through the use of an electrically biased screen or mesh), (3) transporting the non-charged species to a collision region (through the use of the substantial pressure differential and transonic velocity of the energy transferring gas); (4) introducing a precursor deposition feedstock gas into the collision region and; (5) producing large quantities of desirable deposition species within said collision region via the collision of non-charged species of said energy transferring gas with molecules within the precursor deposition feedstock gas; and (6) depositing, at a high deposition rate, quality thin film material onto a substrate which is adjacent to the collision.

  • Publication number: 20070289882
    Abstract: An onboard hydrogen storage unit for a hydrogen powered vehicle including one or more hydrogen storage vessels at least partially filled with a hydrogen storage material which stores hydrogen in metal hydride form. During operation of the hydrogen powered vehicle heat is provided to the hydrogen storage material within the one or more hydrogen storage vessels to aid in desorption of hydrogen from the hydrogen storage material. During hydrogen refueling, heat of hydride formation is removed from the hydrogen storage material within the one or more hydrogen storage vessels to aid in absorption of hydrogen into the hydrogen storage material. The heat of hydride formation is removed from the one or more hydrogen storage vessels via a heat transfer fluid circulated and/or cooled by a stream of compressed air.

  • Publication number: 20070267623
    Abstract: Multi-functional electronic switching and current control devices comprising a material capable of supporting a space-charge. The devices include a load terminal, a reference terminal and a control terminal in contact with the space-charge material and a space-charge region is present at each of the multiple terminals, where each space-charge region includes an equilibrium distribution of spatially-separated charged species. Application of a control signal to the control terminal permits a perturbation of the equilibrium of charged species in the space-charge region of either or both of the load terminal and reference terminal. The space-charge perturbations will induce quantum interactions between the space-charge regions associated with the load and reference terminals that will contribute to modulation or inducement of gain, current control, or conductivity mechanism. The devices may be used as interconnection devices or signal providing devices in circuits and networks.
