摘要： An aqueous dispersion of an embodiment includes visible-light responsive photocatalytic composite microparticles containing tungsten oxide and zirconium oxide, and an aqueous dispersion medium in which the photocatalytic composite microparticles are dispersed. In the photocatalytic composite microparticles, a ratio of a mass of the zirconium oxide to a mass of the tungsten oxide is in a range of from 0.05% to 200%, and a D50 particle size in particle size distribution is in a range of from 20 nm to 10 μm. The aqueous dispersion has pH in a range of from 1 to 9.

摘要： In one embodiment, an antiviral material includes at least one microparticles selected from tungsten oxide microparticles and tungsten oxide composite microparticles. The microparticles have an inactivation effect R of 1 or more expressed by [R=log C−log A], when there is evaluated a virus titer by inoculating on a specimen to which the microparticles are adhered, at least one virus selected from a low pathogenic avian influenza virus (H9N2), a high pathogenic avian influenza virus (H5N1) and a swine influenza virus, and irradiating the specimen with visible light having a wavelength of 380 nm or more and illuminance of 6000 lx. for 24 hours.

摘要： According to one embodiment, provided is an electrochromic device including an electrochromic layer, which contains a tungsten oxide material. The tungsten oxide material includes potassium-containing tungsten oxide particles having an average particle size of 100 nm or less. The potassium-containing tungsten oxide particles contain potassium within a range of 1 mol % to 50 mol %, and include a central section and a peripheral section adjacent to the central section. A periodicity of a crystal varies between the central section and the peripheral section.
