Abstract: An organic light emitting diode (OLED) includes a substrate having a first electrode layer formed thereon in a predetermined pattern, an insulator layer defining the upper portion of the substrate having the first electrode layer in a predetermined pattern, an organic polymer layer formed based on the pattern defined by the insulator layer, a barrier for blocking flow of the organic polymer layer at both ends of the pattern defined by the insulator layer, and a second electrode layer formed on the organic polymer layer.

Abstract: The invention relates to the use of the new poly(p-phenylenevinylene) derivative, poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene-1,2-ethenylene-2,5-dimethoxy-1,4-phenylene-1,2-ethenylene] (M3EH-PPV) as electroluminescent material. The invention is also directed to organic light-emitting diodes (OLEDs) based on the above material, which diodes are remarkable for a significantly increased operating temperature range, as well as to a process for manufacturing said OLEDs by applying said M3EH-PPV directly from a solution in the form of a film onto the substrate or the coated substrate.

Abstract: A shadow mask for a color picture tube a thermal includes insulating layer preventing heat transfer to an apertured shadow mask. The side of the mask directed toward the cathode of the color picture tube is coated with a heat-insulating layer including particles having a porous structure. The pores may contain heavy metals or heavy metal compounds so that electron reflection and absorption occurs directly within the layer. The resulting heat is transferred to the interior of the picture tube instead of to the mask.

Abstract: A process is provided for the electrochemical analysis of compounds of solutions, such as can, e.g., be used in chemical analysis or for control measurements in industrial and environmental sectors. Identification or detection of individual substances takes place by the deposition thereof on electrodes and subsequent detection of the deposited substances. In the process, use is made of a plurality of electrodes. The substances to be identified from the solution are so simultaneously deposited on the electrodes that each electrode is coated with a different substance or substance mixture. Then, the deposited substances are simultaneously identified on the individual electrodes. Thus, the measuring time is significantly shortened and the risk of faulty measurements due to interactions between the substances to be identified on the electrodes is significantly reduced.
