Abstract:
An immunochromatography carried out by illuminating a fluorescent substance in a membrane with excitation light and detecting fluorescence emitted from the fluorescent substance, the immunochromatography comprising the steps of: preparing a membrane having a transparent film, the transparent film being closely attached to the surface of the membrane, the transparent film satisfying a specific property related to a refractive index with respect to analyte liquid; illuminating a fluorescent substance in the membrane with excitation light through the transparent film; and detecting another fluorescence components not exceeding the critical angle, the another fluorescence components being included in the fluorescence emitted from the fluorescent substance, the detection being made by virtue of the fluorescence components passing through the film.
Abstract:
A particulate mixture etc., which can be used as a precursor of lithium transition metal silicate-type compound of small particle size and low crystallinity, is provided. Further, a cathode active material that can undergo charge-and-discharge reaction in room temperature, and comprises lithium transition metal silicate-type compound, is provided.It is a mixture of silicon oxide particulates, transition metal oxide particulates, and lithium transition metal silicate particulates, and its powder X-ray diffraction measurement shows diffraction peaks near 2θ=33.1° and near 2θ=35.7°, and said silicon oxide particulates and said transition metal oxide particulates are amorphous, and said lithium transition metal silicate particulates are in a microcrystalline or amorphous state. Furthermore, a cathode active material obtained by grinding the active material aggregate obtained by heat-treating this particulate mixture is provided.
