  • Patent number: 10153511
    Abstract: Nanoelectrofuel compositions include a plurality of electroactive surface-treated or surface modified nanoparticles dispersed in an electrolyte or self suspended and exhibit fluid characteristics are provided. A Redox flow cell may employ the nanoelectrofuels compositions, wherein the redox flow cell includes a first inlet and a first outlet in fluid communication with a first half-cell body, a second inlet and a second outlet in fluid communication with a second half-cell body, a third cell body, and an ion-conductive membrane separating the first half-cell body from the second half-cell body and defining the second half-cell body.
    Type: Grant
    Filed: May 9, 2014
    Date of Patent: December 11, 2018

  • Publication number: 20140312263
    Abstract: A method for producing nanofluids with multilayered graphene nanoplatelets for providing improved heat transfer coolant fluids. A method for optimizing the concentration of nanoplatelets based on their morphology that allows achieving high thermal conductivity and low viscosity thus resulting in high heat transfer coefficient. A method is provided to functionalize as received graphene nanoplatelets by oxidaitively treating the multilayered graphene/nanothin graphite to generate highly dispensable nanoparticles for suspension in polar fluids for cooling thermal sources, such as power electronics and other heat transfer cooling applications.
