  • Publication number: 20240124365
    Abstract: A preparation method of submicron powder of high-entropy nitride via nitride thermal reduction with mechano-chemical assistance, comprising material preparation—grinding—activation—preforming—reaction. In the present invention, high-entropy metal nitride and silicon nitride is used as raw materials, soft mechanochemical activation technologies are used to reduce reaction activation energy of the system, thereafter, by thermal reduction of the nitride, high-purity high-entropy nitride powder is prepared with solid phase methods, and the shortage of high-purity high-entropy nitride powder is addressed. There is no impure phase in the (Hf0.2Zr0.2Ti0.2Nb0.2Ta0.2)N high entropy powder prepared according to the present invention, and a single phase solid solution of good crystallinity is formed, and distribution of elements and ingredients in the powder is even, no foreign element is present, and oxygen content is controlled to be less than 0.3%.

  • Patent number: 10351706
    Abstract: The invention relates to a near-infrared fluorescent dye and use thereof, and particularly relates to compounds represented by following Formulae A, B and C, wherein each group in the Formulae is described in the specification. Further provided are a dye composition comprising the compound represented by Formula A or Formula B, and a preparation method of the compound represented by Formula A or Formula B. The compound has a maximum absorption wavelength of 880 nm, considerably exceeding maximum absorption wavelengths of the majority of small-molecule near-infrared fluorescent dyes in the prior art. Moreover, the structure thereof does not aggregate even if the concentration thereof is excessively high, thereby having considerably high chemical stability and light stability.

  • Patent number: 8350064
    Abstract: Xanthene compounds are disclosed having fluorescence at multiple wavelengths. Also disclosed are methods for their synthesis and use. Some of the compounds fluoresce at three wavelengths, emitting white light. Uses include the imaging of biological tissues, illumination, and display technologies. Many of the compounds have large Stokes shifts, and are resistant to photobleaching. The fluorescence may be readily distinguished from that of endogenous fluorophores, and from that of most existing, commercially-available fluorescent probes. The compounds are well suited for use in “multiplexing” techniques. They exhibit clear isosbestic and isoemissive points, and have broad absorption and emission ranges.
