  • Patent number: 11499933
    Abstract: A method of manufacturing a graphene-tin oxide nanocomposite comprises dispersing graphene and tin oxide in an organic solvent to prepare a dispersion solution, drying the dispersion solution to obtain a powdery mixture, and irradiating the mixture with microwaves to obtain a graphene-tin oxide nanocomposite. Irradiation of graphene and tin oxide with microwaves results in the simplification of the manufacturing process of graphene-tin oxide nanocomposites and a decrease in manufacturing time and cost, and produce graphene-tin oxide nanocomposites at low temperatures. Further, the graphene-tin oxide nanocomposite with improved sensitivity to NO2 gas may be produced.

  • Patent number: 7440757
    Abstract: A handover method in a wireless communication system is disclosed. A serving base station transmits a handover request message to a base station controller in response to a handover request of a mobile station. The base station controller determines target base stations to which the mobile station can perform handover among target base stations in a list of neighbor base stations, and transmits a handover response message including the determination result information to the mobile station via the serving base station. The mobile station determines a target base station to which it will perform handover, and transmits a message indicating that it will perform handover, to the base station controller via the serving base station. The base station controller transmits a confirm message indicating that the mobile station will perform handover, to the determined target base station, and establishes a tunnel to the target base station.
