  • Publication number: 20230052814
    Abstract: The present disclosure relates to an implantable drug delivery device including a manual control actuator that allows a patient to self-administer a fixed amount of a drug at a desired time. By controlling a drug level, the volume inside a drug chamber, the number of actuations, and the like, a device of the present disclosure allows a drug to be precisely controlled and delivered from the outside after the device is implanted in vivo, and thus it is convenient to control a drug administration schedule. Also, since a battery is not required, and internal control devices for electromagnetic control become unnecessary, it is more patient-friendly and economically feasible.

  • Patent number: 10046333
    Abstract: Provided is a method of restoring arsenic-contaminated soil. In the present invention, arsenic may be easily separated from soil particles by washing the arsenic-contaminated soil by using a basic solution and simultaneously irradiating the soil with ultrasonic waves. Also, since iron oxide and manganese oxide are exposed to the basic solution by dissolving a portion of the surface of a silicate mineral using the basic solution, a residual form of arsenic may be removed.

  • Publication number: 20150292113
    Abstract: The present invention relates to a metal single crystal in which a metal element is substituted, wherein a metal element A is doped with a metal element B different from the metal element A to form A1-XBX, and a mixed single crystal is formed therefrom by high temperature melting (wherein the metal element A is any one of silver, copper, platinum and gold; the metal element B is any one of silver, copper, platinum and gold; and 0.01?x?0.09). Therefore, a metal single crystal, which is a mixed crystal with more superior electrical properties than a conventional metal, is formed by doping a metal with excellent electrical properties with a metal element different from the metal, and growing the doped metal into a mixed crystal.
