Abstract: A thermal conductive stress relaxation structure is interposed between a high-temperature substance and a low-temperature substance to conduct heat in a heat-transfer direction from the high-temperature substance to the low-temperature substance. The structure includes an assembly configured such that a thermal conductive material gathers in a non-bonded state having stress relaxation effect. Such an assembly is a rolled-up body configured such that a carbon-based sheet material and a metal-based sheet material are alternately rolled up, for example. This structure has one or more interfaces at which adjacent parts can slide, thereby dividing a deformable region to relax the thermal stress. It has a low rigidity and can thus deform to release the thermal stress. The structure can suppress the thermal stresses and the shape changes that would be generated in the high-temperature substance and the low-temperature substance, and each physical body located there between.

Abstract: A method for reducing carbon dioxide is provided. In the present method, used is an anode electrode comprises a stacked structure of a photoelectric conversion layer, a metal layer, and an InxGa1-xN layer (where 0<x?1). The InxGa1-xN layer is of i-type or n-type. The metal layer is interposed between the photoelectric conversion layer and the InxGa1-xN layer. When irradiating the anode electrode with light, a first light part included in the light is absorbed by the InxGa1-xN layer and a second light part included in the light travels through the InxGa1-xN layer. The second light part is absorbed by the photoelectric conversion layer to generate electric power in the photoelectric conversion layer. The second light part has a longer wavelength than the first light part. The carbon dioxide contained in the first electrolyte solution is reduced on the cathode electrode.
