  • Publication number: 20050070430
    Abstract: The disclosure relates to zinc oxide-based sorbents, and processes for preparing and using them. The sorbents are preferably used to remove one or more reduced sulfur species from gas streams. The sorbents comprise an active zinc component, optionally in combination with one or more promoter components and/or one or more substantially inert components. The active zinc component is a two phase material, consisting essentially of a zinc oxide (ZnO) phase and a zinc aluminate (ZnAl2O4) phase. Each of the two phases is characterized by a relatively small crystallite size of typically less than about 500 Angstroms. Preferably the sorbents are prepared by converting a precursor mixture, comprising a precipitated zinc oxide precursor and a precipitated aluminum oxide precursor, to the two-phase, active zinc oxide containing component.

  • Patent number: 6722140
    Abstract: A cascade thermoelectric cooler designed to cool to cryogenic temperatures of 30 to 120 K integrates high performance\high-ZT BixSb2−xTe3 and Bi2Te3−xSe3-based super-lattice-structure thin-film thermoelectric devices with a bulk-material based thermoelectric cooler including plural cascaded cold stages with each successive cascaded cold stage able to cool to a progressively lower temperature. Each cold stage in the bulk-material thermoelectric cooler includes a heat source plate, a heat sink plate, a p-type thermoelectric, and a n-type thermoelectric. Moreover, the thin-film thermoelectric cooler can have multiple stages in which each stage contains a heat source plate, a heat sink plate, a p-type super-latticed thermoelectric element, and a n type super-latticed thermoelectric element.

  • Publication number: 20040049517
    Abstract: A method and system for ensuring statistical disclosure limitation (SDL) of categorical or continuous micro data, while maintaining the analytical quality of the micro data. The new SDL methodology exploits the analogy between (1) taking a sample (instead of a census,) along with some adjustments, including imputation, for missing information, and (2) releasing a subset, instead of the original data set, along with some adjustments for records still at disclosure risk. Survey sampling reduces monetary cost in comparison to a census, but entails some loss of information. Similarly, releasing a subset reduces disclosure cost in comparison to the full database, but entails some loss of information. Thus, optimal survey sampling methods can be used for statistical disclosure limitation. The method includes partitioning the database into risk strata, optimal probabilistic substitution, optimal probabilistic subsampling, and optimal sampling weight calibration.

  • Publication number: 20030230332
    Abstract: A thermoelectric device and method of manufacturing the device, where thermoelectric elements of opposite conductivity type are located on respective opposing sides of a heat source member. Heat sinks are disposed on opposite sides of the thermoelectric elements. Peltier metal contacts are positioned between the thermoelectric elements and each of the heat source member and heat sinks. A plurality of devices may be arranged together in a thermally parallel, electrically series arrangement, or in a thermally parallel, electrically parallel arrangement. The arrangement of the elements allow the direction of current flow through the pairs of elements to be substantially the same as the direction of current flow through the metal contacts.
