  • High Verdet Constant Nanoparticles and Methods For Producing and Using the Same
    Publication number: 20220153902
    Abstract: The present invention provides a composition comprising a plurality of magnetic nanocomposite particles. The magnetic nanocomposite particle comprises a magnetic metallic nanoparticle and a plurality of organic polymer ligands attached to its surface. The composition can also include a host matrix, such as a polymer, in which the magnetic nanocomposite particles are interspersed therein. The compositions of the invention have the Verdet constant of at least 5000°/T-m.

  • Cathode materials for Li—S batteries
    Patent number: 10894863
    Abstract: Compositions and methods of producing composite materials for use as a cathode in electrochemical cells. Elemental sulfur is mixed with tungsten sulfide (WS2) to form a composite mixture. Organic comonomers may be added to the composite mixture. The composite mixture is reacted to form the composite material. Electrochemical cells with cathodes containing the composite material demonstrated improved battery performance.
