Abstract: Disclosed is a method for manufacturing an organic electroluminescence device, which decreases the surface resistance at side edges of pixels and increases the uniformity of the pixels, thereby reducing degradation of the device, increasing the life of the device, and improving the displaying sharpness of the device. According to the method, at first, a transparent metal film is deposited on a transparent substrate. Then, the transparent metal film is wet-etched to form anodes respectively having a transverse section whose side profiles are tapered at an angle between 70 and 90 degrees. Thereafter, an organic layer is formed on the anodes and on the substrate, and then cathodes are formed on the organic layer.

Abstract: Disclosed herein are a high-sensitivity method and apparatus for monitoring the concentration or inflow of impurities in circulating water of a circulating water system, which can remarkably improve the measurement sensitivity by converting carbonate ions of low conductivity into chlorine or sulfate ions of increased conductivity, and which can measure the inflow of air or organic substances and the amount of inflow in a simple and efficient manner in real-time. The method of the present invention comprises the steps of: increasing a content of strong acids in sample water and thus increasing equivalent conductivity of the impurities, by utilizing cation exchange resin together with anion exchange resin, in which cations of the sample water are adsorbed on the cation exchange resin to form strong acids while weakly acidic anions of low dissociation degree in the sample water are adsorbed on the anion exchange resin to form strong acids; and measuring the increased conductivity of the impurities.
