  • Publication number: 20230272579
    Abstract: Embodiments of the invention overcome the shortcomings of prior technologies by infusing nanocellulose in a fibrillated form to enhance the properties of cellulose pulp. These properties may include, for example, the mechanical and barrier properties, i.e., tensile strength, liquid, and gas impermeability such as oxygen, carbon dioxide, and oil, can be improved substantially. Another embodiment of the invention further provide a fibrillated cellulose composite material that include properties of being a strength-enhancing agent, an oligomer, carboxylic acid, plasticizer, an antimicrobial agent, water repellant, oil repellant, and/or a transparent composite.

  • Publication number: 20230157738
    Abstract: Systems, devices and methods are provided for implanting medical devices into patients. The systems, devices and methods are particularly useful for orthopedic implants, such as spinal implants that facilitate fusion of bone segments. A fixation assembly for an implant comprises a screw having a head and a shaft, and a washer having at least one outer surface with one or more frictional elements for engaging a surface of the implant. The shaft includes one or more projections that cooperate with the washer to prevent the washer from sliding back down the screw, while allowing for easy application of the washer to ensure optimal placement and desired contact with the screw head. The washer and/or the screw head may also include interlocking cams that create a wedge effect that inhibits the screw from backing out or loosening from a hole in bone or other tissue.

  • Publication number: 20230131336
    Abstract: A material processing apparatus is disclosed. This material processing apparatus is particularly developed to utilize a quasi-traveling microwave to conduct heat treatment for a thread-type article like fiber, silk, artificial fiber, and artificial silk. The material processing apparatus comprises a primary waveguide tube, a microwave blocking plate, a secondary waveguide tube, and at least one microwave absorbing member disposed of in the primary waveguide tube. By such design, a microwave source supplies a microwave to the secondary waveguide tube and the primary waveguide tube, such that the microwave travels in the two waveguide tubes so as to become a quasi-traveling microwave. Therefore, in the case of a thread-type article being be fed into the primary waveguide tube via the secondary waveguide tube by a thread-type article transferring mechanism, the thread-type article is steadily and evenly heated by the quasi-traveling microwave in the two waveguide tubes.
