The invention discloses a fluorescence detection method of a cellulose paper-based sulfur-containing substance and application. A preparation method of a fluorescence probe comprises the following steps: carrying out chemical modification on cellulose twice to obtain modified cellulose; synthesizing a deep red solid product compound 1; and synthesizing a blue-green compound 2. Reacting the modified cellulose with a compound 1 in DMSO (Dimethylsulfoxide) at 100 DEG C for 6 hours; then adding a compound 2 and an aqueous solution in which sodium ascorbate and CuSO4. 5H2O are dissolved; and after freeze drying, washing with ethanol until effluent is colorless, and drying to obtain the red purple cellulose-based fluorescent probe. According to the present invention, the natural polymer cellulose is adopted as the substrate, and the two fluorophores are grafted to construct the near-infrared region ratio type fluorescence sensing platform, such that the cysteine (Cys) and the glutathione (GSH) can be highly selectively distinguished and detected, and the important application value is provided in the fields of biosensing, in vivo imaging and the like.

The application provides an optical system, a control method, a vehicle lamp and a vehicle. The optical system comprises at least one first light source assembly and at least one second light source assembly. The first light source assembly emits light of a first light color when lit alone, and independently or in combination with other light source assemblies, meets the color requirement of a first light function of a vehicle regulation. And / or, the second light source assembly emits light of a second light color when lit alone, and independently or in combination with other light source assemblies, meets the color requirement of a second light function of a vehicle regulation. The light of the first light color emitted by the first light source assembly and the light of the second light color emitted by the second light source assembly are mixed and emitted as light of a third light color, so that the light of the third light color meets the color requirement of a third light function of a vehicle regulation. The first light color is amber or red, the second light color is blue-green or blue, and the third light color is white.

This invention discloses a metal element-doped modified Cu2O catalyst, its preparation method, and its application. The catalyst uses Cu2O as a substrate, with Zn doped into the Cu2O lattice in an atomically dispersed form to form a Zn-O-Cu dual-site synergistic structure. The preparation method is as follows: (1) Dissolve soluble copper salt and polyvinylpyrrolidone in water, then adjust the pH value of the system, and the solution color changes from blue-green to dark brown; (2) Add soluble zinc salt to the suspension and mix evenly; (3) Add a reducing agent and react in a water bath at 50~80℃ for 2~6 hours. After the reaction, separate the product, wash and dry it. This invention promotes the formation of oxygen vacancies in the Cu2O lattice by doping Zn into the cuprous oxide lattice, strengthens CO2 activation and C-C coupling, and effectively inhibits the excessive reduction of Cu during the reaction process, maintaining the stability of the active sites.

A new and distinct plant of ornamental Switch Grass named Panicum ‘Half Pint’ with upright blue-green foliage that retains its coloration into the fall. The upright, compact, and dense culms produce small-height plants with broadly airy panicles beginning greyed green, developing rosy-reddish seed heads that are retained as creamy-tan into winter. The upright foliage and inflorescences produce a tight habit that is narrower than the height of the inflorescences. The new plant is useful in the landscape as a specimen, en masse, or in a container.

The invention relates to the technical field of kits, and discloses a preparation method of a kit for preparing PAGE gels, acrylamide / methylene bisacrylamide, a buffer system (Tris-HCl), an improved coagulant and specific dyes (blue-green, purple, pink and yellow) are mixed, rapid visual distinguishing of gels with different concentrations (7.5%-15%) is realized, and the method is suitable for large-scale industrial production. And the coagulation time of the gel is shortened. According to the invention, ammonium persulfate triggers an acrylamide monomer to polymerize to generate polyacrylamide gel, and sulfate free radicals generated by decomposition of the polyacrylamide gel can accelerate the polymerization reaction, so that the stability and aperture control of the gel are ensured; the color dye solves the problem that the PAGE gel lacks visual distinguishing. The gel thickness is adaptive to combs with different tooth numbers, so that various sample loading requirements are met.

The invention relates to a magnesium-chromium hydrotalcite-like compound-based jungle camouflage coating and a preparation method thereof. The visible-near infrared spectrum of the prepared magnesium-chromium hydrotalcite-like material has a blue-green characteristic, and the near-infrared water absorption peak of the magnesium-chromium hydrotalcite-like material can be increased by intercalating sulfate radicals between magnesium-chromium hydrotalcite-like layers. Besides, due to the fact that the chrome green pigment is small in particle and can cover the near-infrared water absorption peak of the hydrotalcite-like compound, sulfate radical intercalation magnesium-chromium hydrotalcite-like compound is selected to be coated on the basis of Cr2O3, then the coated chrome green pigment and the magnesium-chromium hydrotalcite-like compound are compounded to prepare the jungle camouflage coating, the plant spectrum similarity exceeds 95%, and the jungle camouflage coating has the advantages of being high in spectrum similarity, good in weather resistance, good in corrosion resistance and the like. The synthetic method has the advantages of simplicity, low cost and the like, and has higher military jungle camouflage application value.

A new and distinct plant of ornamental Switch Grass named Panicum ‘October Sky’ with blue-green, upright and arching foliage that red-purple tips and blush in early September. The upright and dense culms produce medium-height plants with airy panicles beginning greyed-green and becoming reddish-purple in September before drying in the fall to tan seed heads that are retained into winter. The new plant is useful in the landscape as a specimen, en masse, or in a container.
