Abstract: The present disclosure relates to a novel bacteriophage having ability to specifically kill Clostridium perfringens and an antibacterial composition comprising the same. The novel bacteriophage CJ_CP_20-25 has the effect of specifically killing Clostridium perfringens, exhibits excellent acid resistance and heat resistance, and can thus be widely used in antibiotics, feed additives, drinking water additives, feed, drinking water, disinfectants, or cleaning agents for the prevention or treatment of infectious diseases caused by Clostridium perfringens.

Abstract: The present application relates to a novel bacteriophage having enterotoxigenic Escherichia coli-specific bactericidal effect and an antibacterial composition comprising same, the novel bacteriophage CJ_Eco_20-4 having enterotoxigenic Escherichia coli-specific bactericidal effect, and being superbly acid and heat resistant to allow wide use in antibiotics, feed and additives therefor, beverages and additives therefor, disinfectants, detergents, and the like to prevent or treat infectious diseases caused by enterotoxigenic Escherichia coli.

Abstract: The present application relates to a novel bacteriophage having Clostridium perfringens-specific bactericidal effect and an antibacterial composition comprising same, the novel bacteriophage CJ_CP_20-11-1 having Clostridium perfringens-specific bactericidal effect, and being superbly acid and heat resistant to allow wide use in antibiotics, feed and additives therefor, beverages and additives therefor, disinfectants, detergents, and the like to prevent or treat infectious diseases caused by Clostridium perfringens.

Abstract: Disclosed herein are a photosensitive resin composition and an organic insulating film prepared therefrom. By optimizing the weight average molecular weight of an alkali-soluble resin and the amount of each component in the photosensitive resin composition, a coated film obtained therefrom may have high planarity property and patterns with high resolution. Accordingly, the photosensitive resin composition may be used as a material for an organic insulating film simultaneously functioning as white pixels in a liquid crystal display.

Abstract: Disclosed herein are a photosensitive resin composition and an organic insulating film prepared therefrom. By optimizing the weight average molecular weight of a copolymer, and using a specific solvent in the photosensitive resin composition, a coated film obtained therefrom may have high planarity property and patterns with high resolution. Accordingly, the photosensitive resin composition may be used as a material for an organic insulating film simultaneously functioning as white pixels.

Abstract: Disclosed is a cathode active material having a core-shell structure. The core-shell cathode active material includes a core including a lithium transition metal oxide with excellent electrochemical properties and a shell formed by coating the surface of the core with a transition metal oxide. The formation of the shell by coating a transition metal oxide on the surface of the core comprising a lithium transition metal oxide prevents the structure of the lithium transition metal oxide from collapsing and inhibits the dissolution of manganese ions, enabling the fabrication of a hybrid capacitor with improved energy density and rate characteristics. Also disclosed is a method for producing the cathode active material.
