Abstract: The thermoelectric conversion element according to the present disclosure comprises a first electrode, a second electrode, a first intermediate layer, a second intermediate layer, and a thermoelectric conversion layer. The first intermediate layer is provided between the thermoelectric conversion layer and the first electrode. The first intermediate layer is in contact with the thermoelectric conversion layer. The first electrode is in contact with the first intermediate layer. The second intermediate layer is provided between the thermoelectric conversion layer and the second electrode. The second intermediate layer is in contact with the thermoelectric conversion layer. The second electrode is in contact with the second intermediate layer. The first electrode and the second electrode are composed of a CuZn alloy. The thermoelectric conversion layer is composed of a thermoelectric conversion material containing Mg. The thermoelectric conversion material contains at least one kind of element selected from the group consisting of Sb and Bi. The thermoelectric conversion material contains at least one kind of element selected from the group consisting of Se and Te. The thermoelectric conversion material has a La2O3-type crystalline structure. A composition of the first intermediate layer is different from both a composition of the first electrode and a composition of the thermoelectric conversion layer. A composition of the second intermediate layer is different from both a composition of the second electrode and a composition of the thermoelectric conversion layer.

Abstract: A desalination method includes: introducing a liquid to a reservoir layer to place the liquid above a water-repellent particle layer; heating and evaporating the liquid placed above the water-repellent particle layer to generate water vapor and deposit impurities on the sheet; liquefying the water vapor by a liquefying layer to obtain fresh water; and removing the sheet on which the impurities have been deposited from a desalination apparatus.

Abstract: The desalination apparatus according to the present disclosure includes: a water-repellent particle layer that is located below a water tank, contains water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the water tank, the water tank being a space for storing the liquid; and a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water. The water-repellent particle layer includes an anti-migration layer provided as a surface layer that faces the water tank and containing anti-migration particles. Each of the anti-migration particles has a higher aspect ratio than the water-repellent particles, the aspect ratio being a value obtained by dividing a length in a major axis direction by a length in a minor axis direction.
