  • Patent number: 10534254
    Abstract: The production of photocatalytic color switching of redox imaging nanomaterials for rewritable media is disclosed. The new color switching system is based on photocatalytic redox reaction enabling reversible and considerably fast color switching in response to light irradiation. In accordance with an exemplary embodiment, the color switching system can include a photocatalyst and an imaging media. With the assistance of photocatalyst, UV light irradiation can rapidly reduce the redox imaging nanomaterials accompany with obvious color changing, while the resulting reduced system can be switched back to original color state through visible light irradiation or heating in air condition. The excellent performance of the new color switching system promises their potential use as an attractive rewritable media to meet increasing needs for sustainability and environmental protection.

  • Patent number: 10436768
    Abstract: The disclosed methods use a multi-phase system to separate samples according to the density of an analyte of interest. The method uses a multi-phase system that comprises two or more phase-separated solutions and a phase component such as a surfactant or polymer. The density of the analyte of interest differs from the densities of the rest of the sample. The density of the analyte of interest is substantially the same as one or more phases. Thus, when the sample is introduced to the multi-phase system, the analyte of interest migrates to the phase having the same density as the analyte of interest, passing through one or more phases sequentially.

    Abstract: A residue remaining on an object to be cleaned after cleaning is easily detected and observed on the object. Adhesive materials 2A and 2B for use in residue confirmation, which are applied in advance to an object 1 to be cleaned for confirmation of a residue remaining on the object 1 after cleaning, are formed by coloring chips produced during cutting work. The adhesive materials 2A and 2B are preferably formed by coating and coloring the chips with paint, the paint emitting visible light in an excited state.

  • Patent number: 8986998
    Abstract: Disclosed herein is a method for identifying the compounds contributing to a pungent odor from an air conditioner, a method for artificially reproducing the pungent odor, and preparing a corresponding pungent odor composition. Through the analysis method of the present invention, the compounds contributing to the pungent odor from an air conditioner may be identified and quantified. The pungent odor may be reproduced from a combination of the compounds identified by the analysis method of the present invention. The reproduced pungent odor may provide significant data required for development of an apparatus and a method for removing specific odors.
