  • Graphene-based PPB level sulfur detector
    Patent number: 11789004
    Abstract: A sensitive and selective, in-line method to measure and validate the sulfur content at ppb levels in both the liquid and gas phase of an analyte. The method includes patterning graphene, for example to form a mesa structure comprising horizontal or vertical lines or an array of multidentate star features; functionalizing the patterned graphene and attaching nanoparticles to the functionalized graphene to form a device; exposing the device to an analyte in the gas or liquid phase; detecting a change in electrical response when sulfur is present in the analyte; and recovering the device for future use. Also disclosed is the related sulfur detector.
    Type: Grant
    Filed: April 12, 2021
    Date of Patent: October 17, 2023
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Evgeniya H. Lock, F. Keith Perkins, Anthony K. Boyd, Rachael L. Myers-Ward, David Kurt Gaskill, Anindya Nath

  • Graphene-based PPB level sulfur detector in fuels
    Patent number: 10976297
    Abstract: A sensitive and selective, in-line method to measure and validate the sulfur content at ppb levels in both the liquid and gas phase of fuel. The method includes etching graphene, for example to form a mesa structure comprising horizontal or vertical lines or an array of multidentate star features; functionalizing the etched graphene and attaching metal oxide nanoparticles to the functionalized graphene to form a device; exposing the device to a fuel in the gas or liquid phase; detecting a change in conductivity when sulfur is present in the fuel; and recovering the device for future use. Also disclosed is the related in-line graphene-based ppb level sulfur detector for fuels.
