Abstract: A polypropylene composite resin composition and a molded article made from same have improved impact resistance. The composition includes: a first propylene-ethylene block copolymer resin having a melt index of 20 to 40 g/10 min (230° C., 2.16 kg); a second propylene-ethylene block copolymer resin having a melt index of 5 to 15 g/10 min (230° C., 2.16 kg); a thermoplastic elastomer including at least one of a styrenic thermoplastic elastomer or an olefinic thermoplastic elastomer; an inorganic filler; and a nucleating agent in appropriate amounts.

Abstract: A circularly polarizing plate capable of improving the tone of reflective color sense by using a retardation film having flat dispersion characteristics; and an OLED device comprising the circularly polarizing plate.

Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

Abstract: A supported catalyst for reduction reaction of nitrogen oxides includes a support and an silver (Ag)-based compound and aluminum fluoride which are immobilized in the support. A method for preparing the supported catalyst for reduction reaction of nitrogen oxides includes an impregnation step wherein aluminum fluoride, a hydrate or a salt thereof, and a silver (Ag)-based compound or a hydrate thereof are reacted with a support and a step of calcining the support. Nitrogen oxides in exhaust gas are removed by reacting with a reducing agent, in the presence of the supported catalyst for reduction reaction of nitrogen oxides. Wherein, the supported catalyst has an excellent nitrogen oxide removal efficiency at a practical exhaustion temperature of 270 to 400° C.

Abstract: A method of reducing nitrogen oxide includes a process of injecting a reductant including an amine compound and an exhaust gas including nitrogen oxide into a catalyst system including a silver alumina (Ag/Al2O3) catalyst.

Abstract: Provided is a plastic interior film having an effect of metallic feeling. The interior film includes a base film; and a pattern layer having one or more pattern selected from a group of a hairline pattern, a mirror pattern, a bead blast pattern, an uneven pattern, an etching pattern and a vibration pattern.
