  • Publication number: 20240170687
    Abstract: A catalyst for fuel cells and a method of manufacturing the catalyst are disclosed. The catalyst forms shells in a dense structure so as to prevent elution of a transition metal and increases dispersibility through hydrophilization of the surface of the catalyst so as to be uniformly dispersed when an ink for forming a fuel cell electrode is manufactured. The catalyst may thus increase the performance and durability of a fuel cell.

  • Publication number: 20240050219
    Abstract: Devices and methods for joining a first and second tissue in a patient are disclosed that include a base with a plurality of recurved tines oriented to a tine axis and extending from a first surface of the base. The tines provide unidirectional traction of the first tissue along the tine axis toward the first surface. The first tissue is secured to the first surface of the device at the plurality of recurved tines and the second tissue is secured to the device at a second surface opposite the first surface to join the first and second tissues.

  • Publication number: 20230113477
    Abstract: Devices and methods for joining a first and second tissue in a patient are disclosed that include a base with opposed first and second surfaces, and a plurality of recurved tines oriented to a tine axis and extending from the first surface of the base. The base defines four suture holes extending through the first and second surfaces of the base and configured to receive at least one suture passing between the first and second surfaces of the base. The plurality of recurved tines provides unidirectional traction of the first tissue along the tine axis toward the first surface to secure the device to the first tissue. The device is secured to the second tissue at the second surface with the at least one suture secured to at least one anchor secured to the second tissue.
