  • Patent number: 12121031
    Abstract: The present invention provides a magnetic biochar-quaternary phosphonium salt bactericidal material, a preparation method therefor and usage thereof, and belongs to the field of water treatment. The preparation method comprises: 1) using corn straw biochar as a precursor to prepare magnetic biochar by a co-precipitation method; and 2) adding the magnetic biochar into deionized water, then adding a quaternary phosphonium salt, performing the magnetic stir at room temperature, raising the temperature after sufficient impregnation, carrying out a hydrothermal reaction, and then cooling to the room temperature to obtain the bactericidal material. The temperature is raised to 60° C.˜70° C.
    Type: Grant

  • Patent number: 10790574
    Abstract: An electronic device and a housing for the electronic device are provided. The housing includes a metal part. The metal part includes at least one spiral slot formed on the metal part A portion of the metal part which is disposed between an innermost loop and an outermost loop of the spiral slot forms a spiral metal coil by being spaced by the spiral slot. The spiral metal coil is configured as an antenna radiation element electrically connected with an antenna circuit inside the electronic device, and the spiral slot is filled with an insulating material.

  • Patent number: 10418965
    Abstract: A positioning method includes: emitting an interrogator signal from an electronic device; detecting, by the electronic device, a response signal that is generated and emitted by a sensor among a plurality of sensors, in response to the interrogator signal; and acquire location information about the sensor by identifying the sensor based on the detected response signal. The response signal is generated based on transduction of the interrogator signal.
