Yunchang Song has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12234564
    Abstract: A preparation method and an application of a three-dimensional structured electric cathode based on cuprous oxide are provided by the present application. The preparation method includes the following steps: cutting copper foam, sequentially subjecting to ultrasonic treatment with acetone, hydrochloric acid, anhydrous ethanol and deionized water, followed by washing and vacuum drying to serve as an electrode substrate for later use; dissolving sodium acetate and copper acetate in deionized water, fully stirring for completely dissolution to obtain a solution, and adjusting a pH value of the solution to be acidic to serve as an electrodeposition precursor solution; and placing the copper foam in the electrodeposition precursor solution, electrodepositing at a predetermined temperature by using a three-electrode system and a potentiostatic method, followed by taking out, washing, and drying to obtain a catalytic electrode.

  • Patent number: 7244372
    Abstract: The present invention relates to a method for increasing the stability of cooling fluid for the engine. This invention selects the most preferred conditions, e.g. the composition of the solution, pH value, means and amount of addition, and proportion of silicate added, so that the products thereof have excellent properties for inhibiting corrosion for many kinds of metals, being with low costs and good storage stability. Moreover, since this method is simple, it is easy to be put into practice and utilized.
