  • Patent number: 10322408
    Abstract: A method for manufacturing a molybdenum disulfide powder includes conducting a precursor solution preparation step and a hydrothermal synthesis step. The precursor solution preparation step includes providing sodium molybdenum oxide dihydrate and thiourea, and conducting a mixing step. In the mixing step, an acid solution is mixed with the sodium molybdenum oxide dihydrate and the thiourea by titrating so as to form a precursor solution. In the hydrothermal synthesis step, the precursor solution is put into a hydrothermal container for reacting at a temperature ranging from 100° C. to 350° C. for 8 hours to 40 hours, thus the molybdenum disulfide powder is formed.

  • Publication number: 20150357996
    Abstract: A radio receiving device, including a positioning module, a radio receiver, a speaker device, and a control unit, and a method of switching frequencies of radio stations are provided. The positioning module obtains a geographic location of the radio receiving device. The radio receiver plays radio information through the speaker device at a first frequency of a radio. The control unit detects a first signal strength of the radio information at the first frequency. When the first signal strength is smaller than a default value, the control unit checks a radio network frequency list according to the geographic location to obtain a second frequency, and detects a second signal strength of the radio information at the second frequency. When the second signal strength is larger than the first signal strength, the radio receiver plays the radio information through the speaker device at the second frequency of the radio.
