Abstract: An Al2O3 thin film layer is fabricated. Atmospheric pressure chemical vapor deposition (APCVD) is processed in a normal atmospheric pressure and a low temperature. On a surface of a p-type or n-type silicon crystal wafer having a purity between 5N (99.999%) and 9N (99.9999999%), the Al2O3 thin film layer is deposited and fabricated. The deposition and fabrication are done to obtain chemical passivation and field effect passivation. In this way, the present invention can be applied in solar cells and other photoelectric devices with reduced leakage of surface currents and improved photoelectric conversion.

Abstract: A cathode electrophoretic deposition (EPD) suspension is provided by mixing an ionomer solution with an electrolyte. An anode EPD suspension is provided via mixing carbon nanomaterial (CNM)-supported catalyst with a solution of the same composition as that of the cathode EPD suspension. Ultrasonication and high-speed stirring are executed on the cathode and anode EPD suspensions, thus turning them into homogenous suspensions. There is provided a low-voltage EPD apparatus incorporated with a porous material to separate it into anode and cathode compartments. The anode and cathode EPD suspensions are filled in the anode and cathode compartments, respectively. An inert gas is introduced into the anode compartment for stirring the anode EPD suspension. An electrode base substrate is used as the anode of the EPD apparatus. A low-voltage direct current (DC) power supply is used to supply DC low voltage to the EPD apparatus, thus evenly coating a catalyst layer on the substrate.

Abstract: An apparatus for monitoring a schedule for testing a fuel cell in a station. Because of the apparatus, the station can test a low-temperature fuel cell or a high-temperature fuel cell. The apparatus enables a user to test the fuel cell through the station manually or enables the station to test the fuel cell automatically.

Abstract: A lens device includes a base, groups of prism-like elements formed on the base and at least two alignment points formed on the base. Each of the groups and a related portion of the base form a lens. Each of the prism-like elements comprises an incidence surface in the form of a camber. The alignment points are used for alignment of a laser device with the lens device.

Abstract: The present invention is to invent a novel method for testing the radiochemical purity of Tc-99m-TRODAT-1 through a high performance liquid chromatography on a widely available C-18 column.
