  • Patent number: 11939603
    Abstract: A modified cutinase is disclosed. The cutinase has the modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of asparagine at position 181 with alanine, or substitutions of asparagine at position 181 with alanine and phenylalanine at position 235 with leucine. The modified enzyme has improved PET-hydrolytic activity, and thus, the high-activity PET hydrolase is obtained, and the industrial application value of the PET hydrolase is enhanced.

  • Publication number: 20230420593
    Abstract: The present disclosure provides a solar cell including a substrate, a first emitter, a second emitter, an insulating spacing structure, a first electrode, and a second electrode. The substrate includes a front surface and a back surface opposite to each other. The first emitter and the second emitter are disposed on the back surface of the substrate. The first electrode is disposed on a side of the first emitter away from the substrate, and the first electrode is electrically connected to the first emitter. The second electrode is disposed on a side of the second emitter away from the substrate, and the second electrode is electrically connected to the second emitter. The insulating spacing structure is disposed between the first emitter and the second emitter, and the first emitter and the second emitter are spaced from each other by the insulating spacing structure.

  • Publication number: 20230323766
    Abstract: A method for estimating a thickness for each of a plurality of nested tubulars may comprise disposing an electromagnetic (EM) logging tool in a wellbore. The method may further comprise transmitting an electromagnetic field from the transmitter into one or more tubulars to energize the one or more tubulars with the electromagnetic field thereby producing an eddy, forming a measurement log from the plurality of measurements, and solving a first inverse problem with uniform priors to obtain a first set of estimated tubular parameters. The method may further comprise designing a data-driven prior based on the first set of estimated tubular parameters, solving a second inverse problem with the data-driven prior to obtain a second set of estimated tubular parameters, and using the second set of estimated tubular parameters to make informed decisions on the integrity of the well casings.
