Abstract: Disclosed is a component for solid oxide fuel cells that is excellent in both electrical conductivity and chromium poisoning resistance. As a substrate, a ferritic stainless steel having a chemical composition containing, in mass %, Cr: 14.0% to 32.0% and Al: 2.50% to 7.00% is used. Precious metal particles are coated on a surface of the substrate. The precious metal particles have: an average particle size of 1 ?m or more and 10 ?m or less; a coating thickness of 0.5 ?m or more and 10 ?m or less; and a surface coverage of 1.0% or more.

Abstract: Methods and compositions for the detection and diagnosis of infectious diseases are provided. In particular, efficient and sensitive methods and compositions for the detection of active mycobacterial disease are provided for distinguishing between individuals having active disease, and individuals who have been immunologically exposed, such as those infected with a mycobacterium but are without active disease, or those who have been vaccinated with BCG. The methods comprise topical application of antigen compositions for transdermal delivery.

Abstract: The present invention is directed to an antimicrobial hydrogel-forming absorbent polymer comprising a hydrogel-forming absorbent polymer, and an antimicrobial comprising a 1-hydroxy-2-pyrrolidone derivative represented by the formula (I); wherein R1 represents an alkyl group having 1-17 carbon atoms, alkenyl group having 2-17 carbon atoms, cycloalkyl group having 5-8 carbon atoms, bicycloalkyl group having 7-9 carbon atoms, cycloalkyl-alkyl group wherein the alkyl group has 1-4 carbon atoms and the cycloalkyl group may be substituted with an alkyl group having 1-4 carbon atoms, aryl group, aralkyl group with an alkyl group having 1-4 carbon atoms, aryl-alkenyl group with the alkenyl group having 2-4 carbon atoms, aryloxyalkyl or arylmercaptoalkyl group with the alkyl group having 1-4 carbon atoms, benzhydryl group, phenylsulfonylalkyl group with the alkyl group having 1-4 carbon atoms, furylalkenyl group with the furyl or alkenyl group having 2-4 carbon atoms, wherein the above-mentioned ary

Abstract: Calcium silicate monohydrate (2CaO.sup.. SiO.sub.2.sup.. H.sub.2 O) can be produced in a coating which has been formed by a coating material containing silica sol alone or silica sol and other additives such as aggregate, viscosity increasing agent, etc. by subjecting the coating to a chemical treatment such as heat-treatment, ultra-violet ray irradiation treatment, etc. in the presence of water and a calcium compound which may be present either in the coating material, or in the treating liquid, or in an object to be coated. The film which contains the calcium silicate monohydrate produced by said chemical treatment has remarkably high hardness and is excellent in water-resistance, water-imperviousness, weather-resistance, and heat-resistance.
