  • Publication number: 20090192030
    Abstract: A polymetallic nanoparticle alloy having enhanced catalytic properties including at least one noble metal and at least one base metal, where the noble metal is preferentially dispersed near the surface of the nanoparticle and the base metal modifies the electronic properties of the surface disposed noble metal. The polymetallic nanoparticles having application as a catalyst when dispersed on a carbon substrate and in particular applications in a fuel cell. In various embodiments a bimetallic noble metal-base metal nanoparticle alloy may be used as an electrocatalyst offering enhanced ORR activity compared to the monometallic electrocatalyst of noble metal.

  • Publication number: 20080151543
    Abstract: An LED light with heat sink is formed from a metal board with holes for mounting lens and reflective cavities inside the metal board, and within the cavities, multiple LED chips are mounted, and with a PCB board on the top of the metal board. One wire pair is connected to an LED light to form external power supply wires. Small holes on the PCB are to mount the lens and the big hole is to let the light through. The LED chips are mounted directly on metal board functioned as heat sink in electrical connection with the wire pairs makes an ultra thin, high brightness, and low cost Power LED Light. The reflective cavities may have single or multiple chips mounted inside with the chips directly mounted on the metal board within the reflective cavity.

  • Publication number: 20070247852
    Abstract: A multi chip LED lamp comprises a reflector and a plurality of LED chips mounted on a top surface of the reflector. A triple laminate board has a board layer; a circuit layer formed on the board layer; and a thermal conductor layer laminated under the board layer. A well is formed in the triple laminate board, the well sized to receive the reflector in snug fit. The multi chip LED circuit layer can be copper and the thermal conductor layer can be aluminum. A heat sink having fins can be attached to the thermal conductor layer. Material can be removed from the triple laminate board to form the well and reflector. Three or more LED chips can be mounted on the top surface of the reflector. The chips can be less than 2 mm from each other.

  • Patent number: 6916570
    Abstract: An oxygen ion conducting ceramic oxide that has applications in industry including fuel cells, oxygen pumps, oxygen sensors, and separation membranes. The material is based on the idea that substituting a dopant into the host perovskite lattice of (La,Sr)MnO3 that prefers a coordination number lower than 6 will induce oxygen ion vacancies to form in the lattice. Because the oxygen ion conductivity of (La,Sr)MnO3 is low over a very large temperature range, the material exhibits a high overpotential when used. The inclusion of oxygen vacancies into the lattice by doping the material has been found to maintain the desirable properties of (La,Sr)MnO3, while significantly decreasing the experimentally observed overpotential.

  • Patent number: 6523211
    Abstract: A self-wringing mop is disclosed comprising a mop stick, an “H” shape frame having one side slidably but not rotatably attached to the mop stick and the other side connected to a short rotating offset that is spaced around five (5) inches apart from the mop stick. A mop head in the form of a bundle of threads has one end connected to the lower end of the mop stick and the other end connected to the lower end of the rotating offset. By turning the driving handle on the rotating offset even a large-size mop head that is more difficult to wring, can be wrung quickly and efficiently.
