Abstract: An information processing device receives material data related to a material, from a user terminal. The information processing device performs analysis on the material data using a predetermined first analysis method and generates first analysis result data that is an analysis result from the first analysis method. The information processing device performs analysis on the received material data using a second analysis method and generates second analysis result data that is an analysis result expressing a relationship between the received material data and data different from the received material data. The information processing device transmits the first analysis result data and the generated second analysis result data to the user terminal.

Abstract: A proton conductor includes a complex of phosphoric acid and a coordination polymer in which a metal ion and a ligand are continuously connected by a coordinate bond. The phosphoric acid includes a first phosphoric acid that is coordinately bonded to the metal ion, and a second phosphoric acid that is not coordinately bonded to the metal ion.

Abstract: A proton conductor includes an anionic molecule and a cationic organic molecule. The anionic molecule is an anionic metal complex molecule. For example, the anionic metal complex molecule includes at least one chemical bond between a metal ion and an oxoacid ion. For example, the proton conductor can be used as an electrolyte membrane included in a fuel cell.

Abstract: A method for manufacturing alumina particles having a size on the order of nanometers and an excellent heat resistance at about 1000° C. comprises providing a liquid medium containing particles made of ?-alumina or boehmite alumina hydrate and a metal component such as La, Ba, Mg or the like, and thermally treated the alumina and the metal component in the liquid medium in a pressurized condition. The thermally treated particles are dried and sintered at a temperature of from 900° C. to lower than 1200° C. to provide alumina particles which has a metal aluminate crystal phase thereon. The metal component is formed as a solid solution as a surface layer of individual alumina particles by subjecting the alumina particles and the metal component to the thermal treatment prior to sintering, so that the metal aluminate crystal phase can be formed by sintering at temperatures lower than ordinary sintering temperatures.
