    Patent Number:
    US 9872870 B2
    Description:

    Embodiments provide systems, methods, and compositions for nanoparticle-based drug delivery to target cells or tissues. A drug delivery system may include a nanoparticle with a targeting component and a therapeutic component. The nanoparticle may have a predetermined number or valence of targeting molecules for multivalent interaction with a target cell or tissue. Binding of the targeting molecules to the target cell may result in receptor-mediated uptake of the nanoparticle by the target cel…

    Patent Number:
    US 10086331 B2
    Description:

    Disclosed herein are methods for CO.sub.2 capture that use phase change ionic liquids (PCILs) to remove the CO.sub.2 from flue gas or other gas streams containing CO.sub.2. PCILs have high CO.sub.2 uptake and form a liquid PCIL-CO.sub.2 complex when they react with C( ).sub.2. When the liquid PCIL-CO.sub.2 complex is heated to regenerate the solid PCIL material by removing the carbon dioxide, part of the heat needed to release the CO.sub.2 can be supplied by the heat of fusion of the PCIL as …

    Patent Number:
    US 10100889 B2
    Description:

    A brake disc rotor or stator is manufactured with slots in the interior face of the disc. A paste comprised of a fine powder of a carbide-forming metal along with fine carbon powder, suspended in an organic binder, is applied to the force-bearing areas in the rotor slot faces or the stator slot faces. The disc is then placed into a furnace in a nitrogen atmosphere and heated to the ignition temperature. When the furnace reaches the ignition temperature, a combustion reaction begins that creat…
