Abstract: The present invention relates to a composition for controlling anti-obesity activity, containing, as an active ingredient, a Moringa oleifera fermentation product prepared using a novel Monascus purpureus SL1 strain, wherein the Moringa oleifera fermentation product provided in the present invention remarkably inhibits the differentiation of adipocytes and the Moringa oleifera fermentation product of the present invention has anti-obesity effects that are remarkably superior to those of Moringa oleifera powder.

Abstract: Disclosed herein is a method for fabricating a membrane-electrode assembly for PEM water electrolysis, whereby the electrode layer can be improved in electrical conductivity. Specifically, a membrane-electrode assembly for PEM water electrolysis, comprising: a polymer electrolyte membrane; an anode disposed on one surface of the polymer electrolyte membrane and containing an anode catalyst; a cathode disposed on another surface of the polymer electrolyte membrane and containing a cathode catalyst; and a platinum layer disposed on the anode, and a fabrication method therefor are provided.

Abstract: Provided are a cathode active material for secondary batteries, the cathode active material comprising a charge-transfer complex in which an electron donor and an electron acceptor are bonded to each other, wherein the electron donor and the electron acceptor are bonded to each other by intermolecular interaction, and a method of producing the cathode active material.

Abstract: Provided is ammunition capable of increasing the movement velocity and shooting range of a bullet and enhancing the target hitting rate. The ammunition includes a case having a propellant chamber and a front mouth, a propellant charged into the propellant chamber of the case, a primer installed in the case for exploding the propellant when a physical or electrical impact is applied thereto, a bullet arranged in the front mouth of the case, the bullet having a streamlined tail portion for reduction of air resistance when the bullet is shot, and a wad fitted to the front mouth of the case for removably holding the bullet and closing the front mouth, the wad being separable from the bullet during explosion of the propellant.
