  • Publication number: 20150171426
    Abstract: Amorphus germanium oxide materials are provided that are composed of germanium and oxygen having a formula GeOx, where 0.01?x?1.99. The germanium oxide forms nanoscale hierarchical porous agglomerates that have high capacity, high diffusivity of lithium, and enhanced cycling stability. The enhanced or superior performance (structural stability and reactivity) of these materials is due to the formation of ultrafine primary nanoparticles, amorphization, pore formation, preferably of nanoscale nature, and the incorporation of oxygen. These amorphous germanium oxide materials may serve as high-capacity anode materials and afford an enhanced capacity applicable for electrochemical cells such as Li-ion batteries.

  • Patent number: 9034165
    Abstract: A method of depositing contiguous, conformal submonolayer-to-multilayer thin films with atomic-level control is described. The process involves the use of underpotential deposition of a first element to mediate the growth of a second material by overpotential deposition. Deposition occurs between a potential positive to the bulk deposition potential for the mediating element where a full monolayer of mediating element forms, and a potential which is less than, or only slightly greater than, the bulk deposition potential of the material to be deposited. By cycling the applied voltage between the bulk deposition potential for the mediating element and the material to be deposited, repeated desorption/adsorption of the mediating element during each potential cycle can be used to precisely control film growth on a layer-by-layer basis. This process is especially suitable for the formation of a catalytically active layer on core-shell particles for use in energy conversion devices such as fuel cells.

  • Patent number: 9005331
    Abstract: Core-shell particles encapsulated by a thin film of a catalytically active metal are described. The particles are preferably nanoparticles comprising a non-noble core with a noble metal shell which preferably do not include Pt. The non-noble metal-noble metal core-shell nanoparticles are encapsulated by a catalytically active metal which is preferably Pt. The core-shell nanoparticles are preferably formed by prolonged elevated-temperature annealing of nanoparticle alloys in an inert environment. This causes the noble metal component to surface segregate and form an atomically thin shell. The Pt overlayer is formed by a process involving the underpotential deposition of a monolayer of a non-noble metal followed by immersion in a solution comprising a Pt salt. A thin Pt layer forms via the galvanic displacement of non-noble surface atoms by more noble Pt atoms in the salt. The overall process is a robust and cost-efficient method for forming Pt-coated non-noble metal-noble metal core-shell nanoparticles.

  • Publication number: 20150045228
    Abstract: A radio frequency-assisted fast superconducting switch is described. A superconductor is closely coupled to a radio frequency (RF) coil. To turn the switch “off,” i.e., to induce a transition to the normal, resistive state in the superconductor, a voltage burst is applied to the RF coil. This voltage burst is sufficient to induce a current in the coupled superconductor. The combination of the induced current with any other direct current flowing through the superconductor is sufficient to exceed the critical current of the superconductor at the operating temperature, inducing a transition to the normal, resistive state. A by-pass MOSFET may be configured in parallel with the superconductor to act as a current shunt, allowing the voltage across the superconductor to drop below a certain value, at which time the superconductor undergoes a transition to the superconducting state and the switch is reset.

  • Patent number: 8921801
    Abstract: A ?-radiation detection system that includes at least one semiconductor detector such as HPGe-Detector, a position-sensitive ?-Detector, a TOF Controller, and a Digitizer/Integrator. The Digitizer/Integrator starts to process the energy signals of a ?-radiation sent from the HPGe-Detector instantly when the HPGe-Detector detects the ?-radiation. Subsequently, it is determined whether a coincidence exists between the ?-particles and ?-radiation signal, based on a determination of the time-of-flight of neutrons obtained from the ?-Detector and the HPGe-Detector. If it is determined that the time-of-flight falls within a predetermined coincidence window, the Digitizer/Integrator is allowed to continue and complete the energy signal processing. If, however, there is no coincidence, the Digitizer/Integrator is instructed to be clear and reset its operation instantly.
