The invention belongs to the technical field of novel functional material design and preparation and provides a preparation method and application of a MnO2/Cu-Al-BTC ternary metal-organic framework material. The preparation method is characterized in that a Cu-Al precursor material excellent in physical and chemical properties is synthesized by using a microwave-assisted heating-impregnation combined method is as the synthesizing method, selecting the mixed liquid of benzoic acid and acetic acid as the stabilizer and using di-mu-hydroxo-bis[(N,N,N',N'-tetramethylethylenediamine)copper(II)] chloride and aluminum 9-octadecenylacetoacetate-diisopropoxide as the metal salt, and then FMES and OP-6 are selected as the molecule inducer to induce MnO2 to enter the framework structure of the Cu-Alprecursor material to prepare a MnO2/Cu-Al-BTC catalyst with ternary metal active sites. The denitrification efficiency of the prepared material reaches 90-96%, and the structural stability of the material can be kept until the temperature reaches 340 DEG C.

The invention discloses a method for synthesizing 2, 3-dichloropyridine (III). The method comprises that 1) pyridine (I) as a main starting raw material and chlorine undergo a full reaction in water or vapor as a reaction medium in the presence of a chlorination inducer to produce a pyridine chloride (II) as the next reaction raw material, and 2) the pyridine chloride (II) as a reaction raw material contacts with hydrogen and undergoes a catalytic hydrogenation reduction reaction in water or vapor as a reaction medium in the presence of an acid-binding agent and a catalyst to produce 2, 3-dichloropyridine (III) having purity of 99% or more, wherein the catalyst is a nanometer IrO2-ZnO-MnO2 composite catalyst. The reaction equation is shown in the description and n is 2-5. The method has the advantages of high reaction conversion rate, high selectivity, stable product quality, simple processes and low cost and solves the problem that the existing synthesis method produces 2, 3-dichloropyridine (III) having unstable quality and satisfying the quality standards after multiple rectification processes.

The invention provides a preparation method of mouse bone marrow macrophages. The preparation method comprises the steps as follows: (1) preparing a complete medium; (2) dislocating cervical vertebraof mice of 6-9 weeks old; (3) taking femur and tibia of the mice, blowing out mouse bone marrow cells, repeating the operation until the bone is colorless, collecting a single cell suspension after blowing, performing centrifuging, and discarding a supernatant; (4) adding a red blood cell lysis buffer to cell precipitate for treatment; (5) adding the mixed solution to a complete medium rapidly forneutralization, performing centrifuging, and discarding a supernatant; (6) adding the complete medium to centrifugal cell precipitate to resuspend cells; (7) inoculating a petri dish with the resuspended cells for culture; (8) after 4 hours, sucking out the suspension cells, inoculating a petri dish of the complete medium containing an inducer with the cells, and recording the day as the first day; (9) changing half of the medium of the cells on the third day, changing the medium every other day until the seventh day, and performing testing. A simple, economical and rapid method for separating the mouse bone marrow macrophages is provided.

The invention provides a platelet aggregation function detection method, a device, a system and a computer readable storage medium. The method includes: controlling the emission of a preset wavelengthoptical signal from a laser emission device to a to-be-detected blood sample, adding a platelet aggregation inducer into the to-be-detected blood sample, performing stirring for coagulation into a stable blood sample; controlling the rotation of a rotary objective platform around the to-be-detected blood sample according to a preset stepping angle, reading an optical receiving module collected optical signal value scattered by the to-be-detected blood sample when the rotary objective platform rotates by one stepping angle; according to the read optical signal values collected by the optical receiving module at all angles and the pre-training acquired fitting coefficients corresponding to the optical signal values of all angles, calculating the platelet aggregation degree of the to-be-detected blood sample. The detection method and device provided by the invention can realize whole blood based detection of the platelet aggregation degree of the to-be-detected blood sample, avoid the centrifugal process, the operation is simple, the detection result accuracy rate is high, the time is short, and the detection instrument cost is low.
