  • Patent number: 10144707
    Abstract: Long-term and high-density energy sources are described that utilize radioisotope batteries that provide a tritium (3H)-based direct energy conversion system. The beta radiation source is a nitroxide compound with a synthetic yield near 100%. The nitroxide compound can be molded into flexible films to cover multiple structures, and has a specific activity and gravimetric density (wt % 3H) comparable to that of tritiated hydrides. A carrier system based on such tritiated nitroxides can be scaled up without significant beta self-absorption, permitting the energy source to have higher specific volume power densities than current radioisotope batteries. Such a carrier can be applied directly to a semiconductor array (such as an integrated circuit) in order to provide electrical power or, alternatively, be prepared with a phosphor and applied to a photovoltaic cell.

  • Patent number: 8828273
    Abstract: Disclosed is a concentrated cooling water additive that is substantially non-corrosive within a pH range of 2-12 and contains polymeric dispersant(s) and aromatic azole(s) that exhibits improved stability, possibly as a result of the interaction of the hydrophobic groups in the dispersant polymer and the aromatic azole(s). This improved stability allows for both reduced corrosivity of the formula and reduced manufacturing costs. Benefits of the disclosed formulations include improved safety for handling and shipment, more concentrated formulations available in liquid form, reduced shipping costs and storage space, reduced heat of neutralization during product manufacture, reduced costs of manufacture due to removal of need for caustic or acid addition and reduced environmental compliance costs associated with washing and waste handling step.

  • Patent number: 8084443
    Abstract: Disclosed are compositions for isolating populations of nucleic acids from biological, forensic, and environmental samples. Also disclosed are methods for using these compositions as one-step formulations for killing pathogens, inactivating nucleases, and releasing polynucleotides from other cellular components within the sample, and stabilizing the nucleic acids prior to further processing or assay. The disclosed compositions safely facilitate rapid sample collection, and provide extended storage and transport of the samples at ambient or elevated temperature without contamination of the sample or degradation of the nucleic acids contained therein. This process particularly facilitates the collection of specimens from remote locations, and under conditions previously considered hostile for preserving the integrity of nucleic acids released from lysed biological samples without the need of refrigeration or freezing prior to molecular analysis.
