Abstract: Provided are a method and system of analyzing ingredients of an artificial rainfall for verification of a cloud seeding effect. As the method and system, which can verify an effect of the artificial rainfall in such a manner that a seeding material becomes different according to each temperature of clouds at a seeding altitude, water sampling from precipitation is performed before and after seeding, and thus the ingredients of a water sample are analyzed using each of a method of analyzing a heavy metal component and a method of analyzing a water-soluble ion component according to a cool cloud and a warm cloud so that whether or not there is a change in each concentration of the ingredients can be determined, are provided, an experiment for the artificial rainfall can more effectively be performed.

Abstract: A positive electrode includes a current collector, a first positive electrode active material layer, and a second positive electrode active material layer. The first positive electrode active material layer is formed on the current collector and the second positive electrode active material layer is formed on the first positive electrode active material layer. The first and second positive electrode active material layers each include lithium iron phosphate, a fluorine-based binder, a rubber-based binder, and a conductive material. The rubber-based binder includes a first hydrogenated nitrile butadiene rubber and a second hydrogenated nitrile butadiene rubber A ratio (P2/P1) of the weight P2 of fluorine contained in the second positive electrode active material layer to the weight P1 of fluorine contained in the first positive electrode active material layer is 1 or less.

Abstract: Disclosed are a method of manufacturing a carbon support for a fuel cell catalyst, a carbon support for a fuel cell catalyst manufactured according to the method, and a catalyst for a fuel cell including the same. The method may include using various organic materials containing N and various carbon supports and thus provide excellent economic feasibility. In addition, pyridinic N and pyrrolic N of doped N can be adjusted at an optimal content ratio so that the carbon support for a fuel cell catalyst manufactured and the catalyst for a fuel cell including the same have excellent electrochemical resistance and excellent electrochemical characteristic due to an increase in an electrochemically active surface area, and excellent durability due to an increase in thermal durability.

Abstract: An image sensor includes a substrate, a photoelectric conversion region in the substrate with the substrate defining a substrate trench on the photoelectric conversion region, a floating diffusion region adjacent to a side surface of the substrate trench, in the substrate, a gate dielectric film that extends along the side surface and a lower surface of the substrate trench and a transfer gate electrode which includes a lower gate that fills a portion of the substrate trench on the gate dielectric film and has a first width, and an upper gate that has a second width smaller than the first width on the lower gate. The gate dielectric film includes a lower dielectric film interposed between the substrate and the lower gate and has a first thickness, and an upper dielectric film adjacent to the floating diffusion region and has a second thickness greater than the first thickness.
