  • Patent number: 11957851
    Abstract: A catheter for guiding a body fluid of a subject includes an elongated body, an adjusting mechanism, and a valve mechanism. Moreover, the elongated body further includes a first portion, a second portion and a flexible portion between the first and the second portions. The second portion includes a passageway for the body liquid. The valve mechanism closes to the inlet of the passageway. Furthermore, the flexible portion expands when the adjusting mechanism is in a first state to prevent the catheter from being removed from the subject, and the flexible portion retracts when the adjusting mechanism alters to a second state to allow the catheter to be removed from or inserted into the subject. Hence, the body fluid is directed to enter the passageway via the inlet and exit via the outlet when the adjusting mechanism is not in the second state.

  • Patent number: 8920612
    Abstract: The innovation process describes the process and results for fabrication of a magnetron sputter deposited fully dense electrolyte layer (8YSZ/GDC/LSGM) embedded in a high performance membrane electrolyte assembly (MEA) (Unit Cell) of Solid Oxide Fuel Cell. A single cell with airtight electrolyte layer (8YSZ/GDC/LSGM) is prepared via thin film technique of magnetron sputter deposition, combined with SOFC-MEA processing methods (such as tape casting, lamination, vacuum hot pressing, screen printing, spin coating, and plasma spray coating) and sintering optimization conditions. The gas permeability of the electrolyte layer is below 1×10?6 L/cm2/sec and the open circuit voltage/power density of the single cell performance test exceeds 1.0 V and 500 mW/cm2.

  • Patent number: 7927693
    Abstract: The present invention provides a high capacity hydrogen storage material in which a plural mesopore channels and fractal networks of nanopore channels communicating therewith and connecting to the micropores are formed in a microporous material, wherein a plural metal particles are formed on the surface of the mesopore and nanopore channels and of the micropores. In another embodiment, the present invention also provides a method for making the hydrogen storage material through oxidizing the microporous material so as to form a plural mesopore channels and fractal networks of nanopore channels, both of which are connected to the micropores to form a base for the deposition of metal particles capable of decomposing hydrogen molecules into hydrogen atoms. The high capacity hydrogen storage material is capable of increasing the capacity of hydrogen storage, and besides, the oxidizing process for making the hydrogen storage material is simple and has merits of saving cost.

  • Patent number: 7815843
    Abstract: This invention describes the process for fabrication of a high conductivity and low resistance solid oxide fuel cell. An anode substrate is mainly prepared via tape casting technique and modified by abrasion and polish process. Electrolyte is fabricated onto the polished side by thin film technologies and can attach well in the cross section. Grinding surface of anode side about 10-30 ?um after finish of MEA combination can get a high conductivity and low resistance unit cell and enhance cell performance effectively.
