The invention discloses a vitamin D3-loaded nano calcium carbonate Pickering emulsion and a preparation method and application thereof, belonging to the technical fields of food and medicine. A preparation method of nano calcium carbonate Pickering emulsion loaded with vitamin D3, comprising the following steps: (1) preparing nano calcium carbonate suspension; (2) high static pressure treatment: subjecting nano calcium carbonate suspension to high static pressure Pressing to obtain nano calcium carbonate dispersion; (3) mixing vitamin D3 with edible oil, stirring under dark conditions to obtain vitamin D3 oil solution; (4) mixing above-mentioned nano calcium carbonate dispersion with vitamin D3 oil solution, Homogenized by shearing. The present invention disperses through high static pressure treatment, which can significantly reduce the agglomeration degree of nano calcium carbonate and improve the dispersibility of nano calcium carbonate particles, so that the finally prepared vitamin D3-loaded nano calcium carbonate Pickering emulsion has Good stability, viscoelasticity and bioresponsiveness.

The invention discloses a simple propagation technique for grating camellia gauchowensis in golden camellia. The technique comprises the steps of S1: stock breeding, S2: grafted mother tree culturing,S3: grafting, S4: management procedures after grafting, wherein grafting in S3 comprises the steps of (1), stock processing; (2), scion collecting and processing; (3), grafting of scion and the stock: the scion is cut into a wedge with two oblique plains which are not completely opposite to each other and presented in angle forming a thicker side and a thinner side; the stock is obliquely cut into deep xylem with an incision in the length of 1.5-2 cm, and the section of the incision is in a shape of the number '7'; the scion is inserted into the section of the stock to make the cambia of thestock and the scion right align with each other; a hormonal bacteriostasis solution is used, and the hormonal bacteriostasis solution is uniformly sprayed on the scion and a grafting interface until the blades and twigs of the scion and the grating interface are uniformly bonded with the solution; a special grafting transparent plastic thin film is adopted for fastening and the grafting is completed. By means of the technique, the surviving rate of the grafting technique is high, the shaping of a tree body is faster, the operation is convenient, the cost is low, the efficiency is high, and grafting is not restricted by seasons.

The invention discloses a preparation method of a Rh nanoflower electrocatalyst for an alkaline direct methanol fuel cell, and belongs to the technical field of eletrocatalysis and energy source. According to the method, polyethyleneimine is taken as a complexing agent and a stabilizer, diethylene glycol is taken as a reducing agent, and RhC13 is reduced to Rh nanoflower with a highly branched structure at one step by a heating method in an aqueous solution. The Rh nanoflower prepared according to the method has a unique structure, high specific area and many active position points, methanol oxidation reaction is catalyzed in an alkaline medium, and the Rh nanoflower has high application prospect; moreover, the prepared Rh nanoflower can have a high electrochemical signal without being subjected to ultraviolet ozone processing, and can be taken as an anode catalyst of the direct methanol fuel cell; and the preparation method of the Rh nanoflower is simple and economic, and is suitable for industrial production at a large scale.

The invention discloses an aqueous acrylic ester adhesive and a preparation method thereof. The adhesive is prepared by the following raw materials: a monomer, a reactive emulsifier, a light stabilizer, an initiator, a hydroxyl terminated polydimethylsiloxane organosilicon modifier, and distilled water; the raw materials are prepared by an emulsion polymerisation method. The preparation method comprises the following steps: the reactive emulsifier, distilled water and the monomer are added into a reaction container, stirring is carried out, and the temperature is controlled at 50-100 DEG C; an aqueous solution of the initiator is added dropwisely, when the system becomes blue, the hydroxyl terminated polydimethylsiloxane organosilicon modifier is added, stirring is carried out continuously, a heat reaction is carried out for 1-3 hours, and the adhesive is obtained. The aqueous acrylic ester adhesive has the advantages of good light stability, good emulsification effects, and high bonding strength.
