Abstract: An electrode mixture includes a sulfide solid electrolyte and a carbon-containing material having contact with the sulfide solid electrolyte. An intensity ratio C/S determined from a spectrum obtained by analyzing the electrode mixture by Auger electron spectroscopy satisfies 0.2?C/S?1, where C is an intensity of a peak in the spectrum which corresponds to carbon included in the carbon-containing material, and S is an intensity of a peak in the spectrum which corresponds to sulfur included in the sulfide solid electrolyte.

Abstract: An electrode material includes: active material particles each containing nickel; and cover layers which cover the surfaces of the respective active material particles, the cover layers each containing niobium. In an X-ray photoelectron spectrum of the electrode material, the ratio A/B of an intensity A of a peak belonging to Nb3d to an intensity B of a peak belonging to Ni2p satisfies 0<A/B<2.

Abstract: The present invention provides a method for adsorbing carbon dioxide onto porous metal-organic framework materials, a method for cooling porous metal-organic framework materials, a method for obtaining aldehyde using porous metal-organic framework materials and a method for warming porous metal-organic framework materials. In each method, porous metal-organic framework materials are used while an electric field or an electromagnetic field is applied to the porous metal-organic framework materials, or while a magnetic field or an electromagnetic field is applied to the porous metal-organic framework materials. If an electric field is applied, at least one organic compound included in the porous metal-organic framework materials is a polar compound. Instead, if a magnetic field is applied, at least one metal included in the porous metal-organic framework materials has an unpaired electron.
