  • Patent number: 10344389
    Abstract: Methods for forming a metal oxide electrolyte improve ionic conductivity. Some of those methods involve applying a first metal compound to a substrate, converting that metal compound to a metal oxide, applying a different metal compound to the metal oxide, and converting the different metal compound to form a second metal oxide. Electrolytes so formed can be used in solid oxide fuel cells, electrolyzers, and sensors, among other applications.

  • Patent number: 10345289
    Abstract: Aspects of the subject disclosure may include, for example, an apparatus having a material having a through-hole, a gate coupled to the material for controlling a charge concentration of the material, a sensor, and a controller coupled to the material, the gate and the sensor. The controller can perform operations including applying a first voltage potential to the material to induce a flow of current in the material, applying a second voltage potential to the gate to adjust the charge concentration of the material, and receiving sensing data from the sensor responsive to a change in electrical properties of the material caused by a target traversing the first through-hole of the material. The through-hole causes a plurality of structural portions of the target to be misaligned with a direction of the flow current in the material. Additional embodiments are disclosed.

  • Patent number: 10337539
    Abstract: An apparatus and system provide drag reduction and energy efficiency for a transport vehicle. Cover sections of transport vehicles are formed to include solar panels comprising photovoltaic cells and dielectric barrier discharge plasma actuator arrays. The vehicle cover also generates electricity to charge onboard battery racks. The cover sections are integral with and shaped to conform with areas such as a trunk lid or roof. Fiber Bragg grating sensors are placed to detect formation of a separation layer. Plasma actuator arrays are actuated either to inhibit formation of the separation layer or to create span-wise waves to reduce skin drag.

  • Patent number: 10256490
    Abstract: An apparatus for separating oxygen from a gas mixture includes an oxide layer having ion transport channels therein, which facilitate the migration of oxygen ions from a first side to a second side of the layer. Molecular oxygen is decomposed into oxygen ions at the first side, whereas oxygen ions recombine into molecular oxygen at the second side. A first chamber into which a gas mixture (e.g., air) is admitted is located on the first side of the oxide layer. A second chamber receives oxygen from the oxide layer, and is located on the second side of the oxide layer; the second chamber has a polarizable medium that is in contact with the oxide layer. A gate electrode in contact with the polarizable medium applies an electric field to the second side of the oxide layer, thereby driving oxygen ions across the oxide layer.
