  • Publication number: 20140242205
    Abstract: Nano-scale particles of materials can be produced by vaporizing material and allowing the material to flow in a non-violently turbulent manner into thermal communication with a cooling fluid, thereby forming small particles of the material that can be in the nano-scale size range. A raw material feeder can be configured to feed raw material toward a heater which vaporizes the raw material. The feeder can include a metering device for controlling the flow of raw material toward the heater. A gas source can also be used to cause gas to flow through a portion of the raw material feeder along with the raw material.

  • Publication number: 20130216921
    Abstract: A system is provided for delivering energy to an electronic device, where the system comprises a metal-air battery having one or more metal-air cells within a housing, a first surface having at least one air hole therein for permitting the influx of air from the surrounding ambient into the interior of the battery housing for exposure to the one or more cells, and a cover that may be entirely or partially moved relative to the air hole for selectively controlling the exposure of the air hole to the ambient when it is desired to generate energy for discharge to the rechargeable power source. The system may include a carriage for positioning the battery therewithin in a removable and/or repositionable manner.

  • Publication number: 20120267297
    Abstract: A process for purification of fluids, for example, desalination of seawater or brackish water, using organic solutes in a concentrated water solution for use in a forward osmosis process, to extract fresh water out of salt water through the forward osmosis membrane, and subsequently separating the organic solutes out of the diluted forward osmosis permeate by cloud point extraction, thereby regenerating a concentrated organic solution for recycling to the forward osmosis process, and fresh water for potable water use.

  • Patent number: 8211594
    Abstract: A composition comprising an admixture of at least platinum particles and metal nanoparticles of metal that, when in admixture with the platinum particles, beneficially alters the characteristics of the platinum, including metals selected from one or more of the metals in groups 3-16, lanthanides, combinations thereof, and/or alloys thereof. The composition could be used to form an ink that further comprises an ionically conductive material, such as a polymer, capable of ionic networking throughout the ink composition so as to create a substantially structurally coherent mass without significantly impacting the reactivity of a substantial number of the nanoparticles. In one application, the ink may be used to form a catalyst whereby the ink is applied to an electrically conductive backing material, such as carbon paper or fibers.

  • Publication number: 20120100986
    Abstract: A gas diffusion cathode for electrochemical cells provides higher power capability through the use of nano-particle catalysts. The catalysts comprise nanometer-sized particles of transition metals such as nickel, cobalt, manganese, iron, palladium, ruthenium, gold, silver, and lead, as well as alloys thereof, and respective oxides. These catalysts can substantially replace or eliminate platinum as a catalyst for oxygen reduction. Cathodes using such catalysts have applications to metal-air batteries, hydrogen fuel cells (PEMFCs), direct methanol fuel cells (DMFCs), direct oxidation fuel cells (DOFCs), and other air breathing electrochemical systems.

  • Publication number: 20110262840
    Abstract: A composition useful for the fueling and refueling of electrochemical devices is described. The composition comprises an ion-conducting medium such as an electrolyte, and catalyst nanoparticles. Unlike traditional electrodes, such as those typically used in electrolyzers and fuel cells, the inventive composition may be quickly drained from the device and refilled to maintain maximum cell performance. In addition, the electro-catalytic charging composition can be stored as a solid for safe handling; for example in a portable cartridge.
