  • Patent number: 11111468
    Abstract: Generation of energy and storage of energy for subsequent use is provided by electromethanogenesis of carbon dioxide into a fuel gas and the storage of the fuel gas for subsequent use. An electromethanogenic reactor includes an anode conductor and a cathode conductor wherein the cathode conductor includes submicron to micron scale pores. Electromethanogenesis microbes and/or enzymes are located in the micron scale pores of the cathode electrode conductor. Carbon dioxide is introduced into the electromethanogenic reactor and the electromethanogenesis microbes/enzymes and the carbon dioxide interact and produce a fuel gas. The fuel gas is stored for subsequent use, for example use in power generation.

  • Patent number: 9739509
    Abstract: A geo-energy production method for extracting thermal energy from a reservoir formation. A production well extracts brine from the reservoir formation. A plurality of working fluid injection (“WFI”) wells may be arranged proximate to the production well to at least partially circumscribe the production well. A plurality of brine production (“BP”) wells may be arranged in a vicinity of the WFI wells to at least partially circumscribe the WFI wells. A working fluid is injected into the WFI wells to help drive a flow of the brine up through the production and BP wells, together with at least a portion of the injected working fluid. Parasitic-load time-shifting and to storing of excess solar thermal energy may also be performed.

  • Publication number: 20160153098
    Abstract: In some embodiments, the present disclosure pertains to methods of mediating a gas evolution reaction by exposing a gas precursor to an electrocatalyst that comprises a plurality of layers with catalytic sites. The exposing results in electrocatalytic conversion of the gas precursor to a gas. Thereafter, the generated gas enhances the electrocatalytic activity of the electrocatalyst by enhancing the accessibility of the catalytic sites to the gas precursor. In some embodiments, the electrocatalyst is associated with an electrically conductive surface (e.g., an electrode) that provides electrical current. In some embodiments, the electrocatalyst is a hydrogen production electrocatalyst that converts H+ to H2. In some embodiments, the electrocatalyst includes a transition metal dichalcogenide. Further embodiments of the present disclosure pertain to the aforementioned electrocatalysts for mediating gas evolution reactions.

  • Patent number: 7829020
    Abstract: A simple and effective system for the colorimetric determination of organic peroxides and hydrogen peroxide. A peroxide pen utilizing a swipe material attached to a polyethylene tube contains two crushable vials. The two crushable vials contain a colorimetric reagent separated into dry ingredients and liquid ingredients. After swiping a suspected substance or surface the vials are broken, the reagent is mixed thoroughly and the reagent is allowed to wick into the swipe material. The presence of organic peroxides or hydrogen peroxide is confirmed by a deep blue color.

  • Patent number: 7518780
    Abstract: A deformable mirror formed out of two layers of a nanolaminate foil attached to a stiff substrate is introduced. Deformation is provided by an electrostatic force between two of the layers. The internal stiffness of the structure allows for high-spatial-frequency shapes. The nanolaminate foil of the present invention allows for a high-quality mirror surface. The device achieves high precision in the vertical direction by using foils with accurately controlled thicknesses, but does not require high precision in the lateral dimensions, allowing such mirrors to be fabricated using crude lithography techniques. Such techniques allow structures up to about the meter scale to be fabricated.

  • Patent number: 7463660
    Abstract: A novel method and apparatus for suppressing ASE and parasitic oscillation modes in a high average power laser is introduced. By roughening one or more peripheral edges of a solid-state crystal or ceramic laser gain media and by bonding such edges using a substantially high index bonding elastomer or epoxy to a predetermined electromagnetic absorbing arranged adjacent to the entire outer surface of the peripheral edges of the roughened laser gain media, ASE and parasitic oscillation modes can be effectively suppressed.
