  • Patent number: 9114387
    Abstract: The present subject matter provides a method of preparing a multicomponent metal-hybrid nanocomposite using co-gasification, in which a multicomponent metal-hybrid nanocomposite can be prepared by a one-step process without using a complicated process including the steps of supporting-drying-calcining-annealing and the like at the time of preparing a conventional alloy catalyst, and provides a multicomponent metal-hybrid nanocomposite prepared by the method. The method is advantageous in that a multicomponent metal-hybrid nanocomposite can be synthesized by a simple process of simultaneously gasifying two kinds of metal precursors, and in that an additional post-treatment process is not required.
    Type: Grant

  • Patent number: 8067062
    Abstract: A platinum-based nano catalyst supported carbon nano tube electrode and a manufacturing method thereof, more particularly to a manufacturing method of a carbon nano tube electrode and a carbon nano tube electrode supported with the platinum-based catalyst by growing the carbon nano tube on the surface of the carbon paper and using a CVD method on the surface of the carbon nano tube. By growing the carbon nano tube directly, the broad surface area and excellent electric conductivity of the carbon nano tube can be utilized maximally, and especially, the nano catalyst particles with minute sizes on the surface of the carbon nano tube by using the CVD method as a supporting method of the platinum-based catalyst on the surface of the carbon nano tube, the amount of the platinum can be minimized and still shows an efficient catalyst effect and by improving the catalyst activity by increasing the distribution, so academic and industrial application in the future is highly expected.

  • Patent number: 5117226
    Abstract: A circuit for generating a scroll screen window signal which is capable of displaying on a display device a desired scroll screen by separating vertically, the screen being displayed in a given corresponding scroll mode. The circuit also compares scroll screen mode signals for discriminating a given mode by use of (+), (-) key input signal representing a scroll type. The improved invention comprises: an OR gate for receiving a basic clock signal 3.
