  • Potentiometric sensor
    Patent number: 11131648
    Abstract: According to one aspect of the invention, a potentiometric sensor having a cathode and an anode. The cathode is configured to provide a summary voltage representative of at least two voltage points. The anode is configured to provide a first voltage. The cathode is in communication with the anode by a first electrolyte forming an open circuit having an open circuit potential. Within the first electrolyte is a concentration of a target ion. The open circuit potential mathematically corresponds to the concentration of the target ion.
    Type: Grant

    Date of Patent: September 28, 2021
    Assignee: U.S. Department of Energy
    Inventors: Guoping Cao, Shelly X. Li, Steven Herrmann, Brenda Serrano-Rodriguez

  • Arc-enhanced friction stir welding
    Patent number: 7078647
    Abstract: Friction stir welding is enhanced by preheating of the workpiece with an electrical arc, such as an arc applied by a common gas-tungsten arc welding (GTAW) torch. As the arc is moved about a path on the workpiece, it preheats or partially welds the path, with the friction stir welding head following along the path to complete the weld.
