  • Patent number: 9779872
    Abstract: One embodiment relates to an apparatus for adjustment of local magnetic strength in a magnetic device. A stage holds the magnetic device, and a sensor measures a magnetic field at locations above the magnetic device so as to generate magnetic field data. A computer system detects a non-uniformity in the magnetic field from the magnetic field data and determines a location and a duration for application of a pulsed laser beam to correct the non-uniformity. A laser device applies the pulsed laser beam at said location for said duration. Another embodiment relates to a method of adjusting local magnetic strength in a magnetic device. Another embodiment relates to a system for fine-tuning a magnet array with localized energy delivery. Other embodiments, aspects and features are also disclosed.

    Abstract: The present invention relates to a zinc oxide-cellulose nanocomposite made of cellulose and zinc oxide nanoparticles and to a preparation method thereof. The nanocomposite of the present invention is prepared by producing zinc oxide nanoparticles as seeds on the surface and/or inside of a cellulose film and growing the seeds into zinc oxide crystals to form a zinc oxide layer strongly attached to the cellulose film. The nanocomposite of the present invention has significantly improved piezoelectricity compared to simple cellulose piezoelectric paper and may be used for LEDs and photovoltaic power generation devices thanks to zinc oxide doped therein.
