    摘要: A novel method and device for the destruction of nitrous oxide in gases such as those resulting from exhaled breath during dental, medical, and veterinary procedures are described. The method employs processing steps including the collection of gases containing constituents such as water vapor, carbon dioxide, oxygen, nitrogen, and nitrous oxide from exhaled breath or from ambient room air, optional removal of moisture from the collected gas, catalytic decomposition of nitrous oxide gas to nitrogen and oxygen, heat exchange to reduce high temperatures in gases exiting the reactor, and sorbents to remove traces of reaction byproducts. Instrumentation and controls are employed to monitor and regulate temperatures, pressures, gas compositions, and flow rates while also providing measures to automatically shut down in the event of off-nominal conditions. The method and device are capable of operating with variable anesthetic or patient exhaled breath flow rates while inducing no significant pressure or vacuum on the patient as they exhale. The method is carried out in a compact device suitable for operation in dental offices, hospitals, and other locations where nitrous oxide is administered as an anesthetic.

    摘要: Gas Replacement System (GRS) produces lighter than air lift gas from ammonia to enable balloon launch and/or to extend the flight durations of balloons. The GRS produces lighter than air lift gas by dissociating all or part of an ammonia supply into a mixture of nitrogen and hydrogen. The GRS can be used to launch balloons from the ground and/or produce gas for airborne balloons to extend their flight duration. In one embodiment, a GRS includes a tank containing ammonia (e.g., liquid ammonia), a reactor, and a controller operable to direct a release of the ammonia from the tank to the reactor. The controller is also operable to direct the reactor to dissociate at least a portion of the ammonia into a lift gas and exhaust the lift gas from the reactor into the balloon for inflation, the lift gas comprising nitrogen and hydrogen.

    摘要: A novel photocatalytic oxidation system that combines long lifetime, high-power light emitting diodes (LEDs) with efficient, visible light-activated photocatalysts for the destruction of Volatile Organic Compounds (VOCs) and other pathogens in air and water flow systems under ambient conditions of temperature and pressure is described. The technology uses the combination of visible photocatalysts with robust visible LEDs, uniform side emission fiber optics, and efficient catalyst surface illumination technologies to create a photocatalytic oxidation unit for air and water purification. This combined approach leads to numerous performance benefits including high VOC conversion efficiency, compact reactor volume, low pressure drop, and the elimination of conventional ultraviolet (UV) mercury lamp logistics and hazards.

    摘要: Systems and methods herein provide for balloon launching. In one embodiment, a Portable Balloon Launch System (PBLS) includes a tank operable to retain water, and a reactor fluidly coupled to the tank and comprising a reductant material that reacts with the water to produce a lift gas. The PBLS also includes a first valve operable to release the water into the reactor, and an exhaust operable to vent the lift gas into a balloon to inflate the balloon. The lift gas is lighter than air so as to lift the balloon into the atmosphere.

    摘要: Systems and methods for recovering cobalt and other valuable metals from cobalt permanent magnets of various compositions, such as samarium cobalt magnets, are presented herein. In one embodiment, a method includes converting the permanent magnet material to a higher surface area form, such as a powder. The method also includes treating the converted permanent magnet material with an aqueous solution of ammonium carbonate to form a mixture (e.g., a slurry) that includes dissolved cobalt. In some embodiments, the method includes exposing the mixture to an oxidant to oxidize metallic constituents and form soluble species. The method also includes filtering the mixture to yield a filtrate and electroplating the cobalt onto a cathode from the filtrate.

    摘要: Systems and methods for recovering neodymium and other related rare earth elements from permanent magnets and/or various ore compositions are presented herein. In one embodiment, a method of recovering a rare earth element (REE) from a permanent magnet material and/or a mined ore composition (collectively “work material”) is presented. The method includes converting the work material to a higher surface area form, treating the converted work material with an aqueous solution of alkaline carbonates to dissolve the REE, filtering the treated and converted work material to yield a filtrate, and treating the filtrate with at least one of a precipitating agent or a precipitating condition to form REE solids. The aqueous solution of alkaline carbonates comprises at least one of potassium carbonate, potassium bicarbonate, or dissolved carbon dioxide.

    摘要: Novel methods of recovering neodymium and related rare earth elements from permanent magnets of various compositions are described. The methods employ processing steps including converting the magnet material to a higher surface area form such as a powder, treating the mixture with alkaline solutions to form product concentrated in neodymium and rare earth metals. Inexpensive materials such as ammonia, ammonium carbonate, carbon dioxide, water are recycled in a process that uses moderate temperatures, pressures and non-corrosive and environmentally-friendly chemicals.
