  • Patent number: 8083305
    Abstract: A refrigerator is provided, by which cold air can be effectively prevented from leaking from a storage room. The refrigerator includes a refrigerator body having an opening and a storage room provided therein, a door closing/opening, a sealing part provided to at least one of the door and the refrigerator body to prevent a cold air from leaking from the storage room, and a flow cutoff part provided inside the sealing part to prevent the cold air flowing toward the sealing part from the storage room. Accordingly, by cutting of the cold air leakage together with the sealing part, energy efficiency of the refrigerator can be raised.

  • Publication number: 20110116996
    Abstract: A method of physicochemical leaching valuable metals is able to increase the leaching rate of nickel and magnesium contained in laterites, nickel ores, with a low concentration acid solution by using mechano-chemical effect. That is a method to add external energy to laterites containing nickel and magnesium to physically disintegrate their crystals and exposure nickels captured inside of the crystals to leach nickel and magnesium with a low concentration acid solution. It is a useful method to solve conventional problems such as the high energy cost of pyrometallurgical treatment and excessive use of strong acids of hydrometallurgical method.
