Abstract: Proposed are a precursor for forming a lanthanide metal-containing thin film, the precursor being characterized by including a compound represented by Chemical Formula 1, a method for forming a lanthanide metal-containing thin film using the same, and a semiconductor element including the lanthanide metal-containing thin film. The precursor contains a lanthanide metal as the core metal atom and includes a cyclopentadienyl ligand providing properties such as a low melting point and high volatility, as well as a novel amidinate ligand that provides high structural stability, low viscosity, high volatility, high thermal stability, and properties such as being a liquid at room temperature or a solid with a low melting point. Therefore, the precursor exhibits physical properties suitable for use in a thin film formation process and thus can form a high-quality thin film.

Abstract: Disclosed is a method of quantifying furan concentration to efficiently manage a deterioration state of a transformer in the field. The method of quantifying furan concentration includes: measuring a color-development degree of an extraction solution by making the extraction solution containing furan extracted from an insulating-oil sample mix and react with a color reagent; and quantifying furan concentration by correction based on a correlation between a precise analysis and a simple analysis with regard to the color-development degree of the extraction solution, wherein the precise analysis is to obtain a quantitative value through color column separation based on high performance liquid chromatography (HPLC) in a laboratory to analyze a furan compound in insulating oil of a transformer, and the simple analysis is to obtain a chromaticity value in a field with regard to actual transformer samples.

Abstract: Provided is a high-temperature fuel cell separator. The fuel cell separator includes a fuel gas flow path containing hydrogen, an oxidant gas flow path containing mainly an oxygen component being supplied from an oxygen/nitrogen separator of a system and participating in electrochemical reactions, and a cooling gas flow path containing a nitrogen component to remove heat produced upon power generation of a fuel cell. Such a configuration provides a high-temperature fuel cell separator which is capable of improving efficiency of an overall fuel cell system through improved performance of a fuel cell stack due to increased oxygen partial pressure and which is also capable of improving reliability of the fuel cell stack through inhibition of the occurrence of a high-temperature region resulting from heat produced upon power generation of a fuel cell, by means of a flow of cooling gas containing a nitrogen component.
