A refrigerator is provided which includes a variable temperature storage formed in the chilling chamber; a heating room formed on a side of the variable temperature storage; a heating device installed in the heating room and configured to generate heat; a first local circulating path in which cool air in the freezing chamber flows into a rear path through the variable temperature storage; an adjusting device configured to adjust a quantity of cool air flowing into/out of the variable temperature storage through the first local circulating path; a second local circulating path in which heated air in the heating room passes the variable temperature storage and flows into the heating room again; and a temperature sensor configured to sense a temperature in the variable temperature storage. Because various ranges of temperature can be maintained in the refrigerator, it is possible to perform optimum-temperature storing according to various kinds of foods. Accordingly, various kinds of foods can be stored freshly for a longer time.

Disclosed are a chemically modified polyolefin elastomer composition that is highly compatible with thermoplastics and useful in improving the low temperature impact strength of thermoplastics, and a method for preparing the chemically modified polyolefin elastomer composition. The elastomer composition includes a polyolefin resin and a chemically modified ethylene-α-olefin elastomer mixed with the polyolefin resin. The chemically modified ethylene-α-olefin elastomer includes an ethylene-α-olefin elastomer backbone and grafted branches from the backbone. The branches includes polymers of one or more monomers comprising an unsaturated organic compound containing at least one carbonyl group. The method of producing the composition includes mixing an ethylene-α-olefin elastomer and a polyolefin resin to provide a mixture thereof, to which added is one or more monomers having an unsaturated organic compound containing at least one carbonyl group. Then the one or more monomers are polymerized in the presence of a grafting initiator.

A method of removing lead sulfide contained in refined molybdenite powder concentrates (major component; MoS2) is provided. More specifically, in order to solve the problems associated with a leaching method using a leaching agent that is employed for conventional hydrometallurgical process, oxygen-free inert gas is circulated in a furnace for pyrometallurgical treatment to evaporate lead sulfide at high temperature, followed by condensing process to recover lead sulfide at low temperature. The method is characterized in that, it can reduce environmental contamination and can easily recover sulfides of valuable metals such as lead, indium, zinc and the like.
