  • Enhanced electron mobility at the interface between GD2O3(100)/N-SI(100)
    Patent number: 9000432
    Abstract: A multilayered structure is provided. The multilayered structure may include a silicon substrate and a film of gadolinium oxide disposed on the silicon substrate. The top surface of the silicon substrate may have silicon orientated in the 100 direction (Si(100)) and the gadolinium oxide disposed thereon may have an orientation in the 100 direction (Gd2O3(100)).
    Type: Grant
    Filed: June 25, 2014
    Date of Patent: April 7, 2015
    Assignee: The University of North Carolina at Charlotte
    Inventors: Raphael Tsu, Wattaka Sitapura, John Hudak

  • Self-cleaning submerged instrumentation
    Publication number: 20100042389
    Abstract: Techniques and apparatus inhibit, limit, or remove biofouling and certain inorganic accumulations, to increase the longevity of accurate in-situ oceanographic and other underwater measurements and transducing processes. The invention deters formation of an initial bacterial layer and other precipitation, without harming the environment. The invention integrates an ultrasonic source into a sensor or other device, or its supporting structures. The ultrasonic source vibrates one or more critical surfaces of the device at a frequency and amplitude that dislodge early accumulations, thus preventing the rest of the fouling sequence. The ultrasonic driver is activated for short periods and low duty cycles, and in some cases preferably while the device is not operating.

  • Methods and apparatus for performing engine maintenance
    Publication number: 20070130767
    Abstract: A maintenance tool for a gas turbine engine includes a housing coupled to the gas turbine engine, and a drive portion inserted at least partially through the housing. The drive portion is configured to enable the gas turbine engine to be selectively rotated during non-operational periods. Moreover, the maintenance tool is coupled to the gas turbine engine during normal operation.

  • Vehicle fuel tank with two ingress fuel conduits
    Publication number: 20060180367
    Abstract: A fuel tank for a self propelled motor vehicle includes first and second fuel ingress conduits each attached at one end to the fuel tank and at the other end to the side of the motor vehicle, preferably on opposite sides of the motor vehicle. The first and second fuel ingress conduits are arranged with respect to the motor vehicle to facilitate filling of the fuel tank from a fuel source positioned external to the motor vehicle on either side of the motor vehicle.
