The nucleation step includes forming non-contiguous metal nuclei by depositing a metal by MOCVD using a metalorganic precursor on the top face of the substrate and oxidising the metal of the metal nuclei, to form oxidised nuclei and ensure stabilisation of the nuclei. The growth step includes depositing a metal by MOCVD using the metalorganic precursor, to form non-contiguous nanostructures by growth of the oxidised nanostructures, and oxidising the deposited metal of the nanostructures formed in the nucleation to form oxidised nanostructures.

  • Publication number: 20230314358
    Abstract: Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences.

  • Patent number: 11725626
    Abstract: The present invention relates to a method of controlling a wind turbine by automatic online selection of a controller that minimizes the wind turbine fatigue. The method therefore relies on an (offline constructed) database (BDD) of simulations of a list (LIST) of controllers, and on an online machine learning step for determining the optimal controller in terms of wind turbine (EOL) fatigue. Thus, the method allows automatic selection of controllers online, based on a fatigue criterion, and switching between the controllers according to the measured evolution of wind condition.
