Abstract: The purpose of the present invention is to provide a cell culture substratum which has excellent resistance to liquid culture media and low cytotoxicity, can achieve a high cell adhesion ratio and a high viability of cultured cells, has excellent thermal stability, and is less likely to absorbs ultraviolet ray. A cell culture substratum which is provided with a substrate made from an inorganic material and has multiple concavo-convex structures on a culturing surface thereof, wherein, when the concavo-convex structures are measured with an atomic force microscope in accordance with JISB0601 and JISR1683 (measured area: a 1 μm-square, cut-off value of a low-pass contour curve filter: 1 nm, cut-off value of a high-pass contour curve filter: 170 nm), the average of the lengths of contour curve elements of the concavo-convex structures is 1 to 170 nm as measured in at least one direction (when a curve showing long-wavelength components that are blocked by the high-pass contour curve filter is converted to a straight line by the least square method, the average line is a line that is parallel with the straight line and indicates a height cumulative relative frequency distribution in the contour curve of 50%).

Abstract: Provided are a rotary device for fluid power generation and a fluid power generation device that are capable of converting the kinetic energy of a fluid to an electric energy. By utilizing a longitudinal vortex as a driving force, a rotary body such as a cylinder as a high-strength and tough wing-shaped member can be rotated, and power can be efficiently generated in a wide range of flow rate without letting the longitudinal vortex disappear even if the flow rate changes in a wide range. This rotary device for power generation includes a rotary body 3; and a wake body 8 that is a distance away from the rotary body 3 toward the downstream side of a flow direction 10 of the fluid, and has at least one crossover section at which the wake body 8 intersects with the rotary body 3.
