    摘要： The present invention addresses the problem of providing a laminated film that has further uniform properties regarding optical characteristics and the like, and that can maintain said properties for a further extended period of time. This laminated film is characterized by comprising two or more different types of thermoplastic resin layers and is characterized in that, when ratios of interface layer thicknesses analyzed through GCIB-TOF-SIMS with respect to the film thickness are calculated in all types of interfaces formed by the different thermoplastic resin layers, the lowest value thereof is 1.0×10−4−1.0×10−2.

    摘要： A method of manufacturing a membrane-electrode assembly including an electrolyte membrane and a catalyst layer-formed gas diffusion layer bonded to the electrolyte membrane, the method including: a liquid application step of applying, in the atmosphere, a liquid to only a surface of the catalyst layer before bonding; and a thermocompression bonding step of bonding, to the electrolyte membrane, the catalyst layer-formed gas diffusion layer to which the liquid is applied, by thermocompression bonding. Provided is a method of manufacturing a membrane-electrode assembly including a polymer electrolyte membrane and a catalyst layer-formed gas diffusion layer bonded to the polymer electrolyte membrane, in which the manufacturing method can achieve both the relaxation of thermocompression bonding conditions and the improvement of adhesion between the catalyst layer-formed gas diffusion layer and the electrolyte membrane with high productivity.

    摘要： To provide a carbon fiber bundle capable of suppressing winding due to ring-shaped fuzzes, which occurs when the carbon fiber bundle is rolled out for advanced processing, and a production method for producing the same. Disclosed is a carbon fiber bundle wherein an average single-fiber diameter B is 6.9 to 11.0 μm, a tensile modulus E of resin-impregnated strands is 230 to 310 GPa, the number of fuzzes inherent in the carbon fiber bundle is 40 fuzzes/m or less, and a proportion of fuzzes with a structure having a difference between skin and core is 1 to 25% of fuzzes inherent in the carbon fiber bundle. Such a carbon fiber bundle is preferably obtained by a method including, in a process of heat-treating a polyacrylonitrile-based precursor fiber bundle with a single-fiber fineness of 0.9 to 2.2 dtex in an oxidizing atmosphere at 200 to 300° C., heat-treating the polyacrylonitrile-based precursor fiber bundle so that a heat generation rate Q, which is the left side of the formula (3), is 150 to 500 J/m2/s until the density is 1.22 to 1.24 g/cm3, when q (J/g/s) is the heat generation rate of the single fiber, N is the number of filaments, d (dtex) is a single-fiber fineness of the stabilized fiber bundle and W (mm) is a yarn width, heat-treating the fiber bundle while applying a tension of 1.6 to 4.0 mN/dtex until the density is 1.38 to 1.50 g/cm3 to obtain a stabilized fiber bundle, and heat-treating the stabilized fiber bundle in an inert atmosphere at 1,200 to 1,600° C.

    摘要： The microRNA detection level decreases when a microRNA-containing biological sample is preserved after being collected. Further, a relatively long period of time is required for dissolving a hydrochloride of a neutral amino acid, which is in the form of crystals, in water. Since a hydrochloride of a neutral amino acid is an acidic substance, and causes skin irritation and mucosal irritation, the handling of the hydrochloride requires safety precautions. The present invention provides a method of detecting a microRNA in a biological sample, the method including the steps of: mixing an acid with the biological sample, preserving the resulting mixture for a predetermined period of time, collecting the microRNA in the biological sample, and detecting the microRNA. Further, the present invention provides a homogeneous semi-solid composition composed of a hydrochloride of a neutral amino acid, water and an alcohol.
