  • Patent number: 10175557
    Abstract: There is provided an optical wavelength conversion element with a good temporal stability and such a high optical wavelength conversion efficiency that the element is viable even under sunlight or similar, low intensity light. Owing to these properties, the element is suited for use in solar cells, photocatalysts, photocatalytic hydrogen and oxygen generating devices, photon upconversion filters, and like articles. The optical wavelength conversion element is visually homogeneous and transparent and produced by dissolving and/or dispersing in an ionic liquid (C) a combination of organic photosensitizing molecules (A) and organic light-emitting molecules (B) that exhibits triplet-triplet annihilation.

  • Publication number: 20150323937
    Abstract: A fluid control system includes a fluid device including a flow channel including a reaction part in which a first fluid is subjected to a reaction, and a position control apparatus. The position control apparatus includes a position information acquisition unit that acquires information of a position of an interface between the first fluid and a second fluid in the flow channel or between the second fluid and a third fluid in the flow channel. The position control apparatus controls the position of the first fluid in the flow channel based on the information of the position acquired by the position information acquisition unit. The information of the position by the position information acquisition unit is acquired in an interface detection part located upstream or downstream with respect to the reaction part and having a smaller average cross section than in the reaction part.
