The invention relates to a corneal contact lens achieving controlled drug release. The corneal contact lens comprises a semipermeable membrane layer, a water-absorbing expansion layer, an impermeableelastic membrane layer and a drug storage layer which are arranged in sequence from bottom to top; the drug storage layer is provided with a storage cavity used for storing drugs and a microchannel allowing the drugs to flow out, the semipermeable membrane layer makes contact with the cornea, and allows water in tears to enter the water-absorbing expansion layer, the elastic membrane layer isolates the storage cavity of the drug storage layer and the water-absorbing expansion layer, when the water-absorbing expansion layer absorbs the water in the tears to expand, the storage cavity is compressed through the elastic membrane layer, and the drugs can be lowly released to the eye through the microchannel. Accordingly, drug release is conducted on the eye in a non-invasive mode, and pain of apatient in an operation is avoided; drug release is achieved through imbibition actuating, and can last for longer time, and more and diverse drugs can be stored.

The invention provides self-leavening flour with rich selenium, which includes raw materials by the weight percentages as follows: flour 100.0%, Mary leaven with high sugar 1%-1.2%, sweet baking powder 1.2%-1.8%, soft sugar 2.0%-3.0%, iodized edible salt 0.3%, steamed bread flour modifier 0.1%, malt flour with rich selenium 0.2%, glucolactone 2.0%, and saleratus 1.0%. When in use, the inventive self-leavening flour with rich selenium can be formed after fermenting for 30 minutes, and then be steamed on a tray to make steamed bread or other fermented food. The using process of utilizing biological agents and food agents is fast, sanitary and safe.

The invention belongs to the technical field of livestock breeding, and relates to a feed for beef cattle fattening. The feed comprises 200-400 parts of corn, 250-350 parts of barley, 50-200 parts of soybean meal, 30-150 parts of corn germ meal, 30-60 parts of corn DDGS, 5-15 parts of stone powder, 3-10 parts of calcium hydrophosphate, 3-10 parts of edible salt, 2-5 parts of organic calcium magnesium, 2-10 parts of yeast culture, 2-5 parts of an active microecological preparation, 1-2 parts of trace element premix, 0.2-1 part of rumen bypass vitamin and 1-5 parts of rumen bypass amino acid; and the organic calcium magnesium is a mixture of sodium alginate and magnesium alginate. According to the feed, the organic calcium-magnesium mixture of the sodium alginate and the magnesium alginate is added, so that the regulation effect on rumen is effectively improved, rumen acidosis is relieved, the feed intake of dry substances is increased, and the average daily gain is increased.

The present invention discloses an oil-in-water Pickering emulsion with stable ursolic acid and a preparation method of the oil-in-water type Pickering emulsion. The oil-in-water Pickering emulsion with the stable ursolic acid is prepared from the following raw materials in percentages by mass: 2-4% of ursolic acid, 2-8% of propylene glycol, 1-2% of phospholipid, 20-40% of functional grease, 0.04-0.2% of sucrose ester, 0.15-0.5% of tween 80, 0.5-1% of protein, 0.02-0.04% of a thickening agent and water. By constructing and utilizing the Pickering emulsion of the ursolic acid combined with a surfactant, multilayer microcapsule recombinant powder is prepared. The oil-in-water Pickering emulsion has characteristics of being green and safe, good in stability, high in compatibility, good in dispersibility, high in uniformity, excellent in instant solubility, etc.

The invention relates to a bismuth ferrite / sepiolite composite visible-light-driven photocatalyst and a preparation method thereof. The preparation method comprises the following steps: by taking soluble bismuth salt and ferric salt as raw materials, fully mixing solutions of the two raw materials, regulating the pH value of the solution by using strong base, adding treated purified sepiolite, performing ultrasonic stirring and full mixing, transferring the treated system into a polytetrafluoroethylene autoclave, and performing hydrothermal reaction, so as to generate the porous bismuth ferrite / sepiolite composite visible-light-driven photocatalyst which is based on sepiolite and has good morphology. Bismuth ferrite is generated on line in the presence of sepiolite, and the structure and morphology of the generated bismuth ferrite are effectively regulated and controlled under the combined action of rich oxygen-containing groups on the surface of the sepiolite and an interfacial effect, so that the component integration and the material stability in the prepared bismuth ferrite / sepiolite composite visible-light-driven photocatalyst are improved, the recombination rate of an energy band gap and a photon-generated carrier is reduced, and the absorption and utilization rate of visible light, the adsorption performance on organic pollutants and the visible light catalytic degradation performance and mineralization effect on the organic pollutants are improved.

The invention provides a selenium-enriched disease-resistant base fertilizer for rice and a preparation method thereof and belongs to the field of farming. The base fertilizer is prepared from the following raw materials in parts by weight: 20-25 parts of rice stems, 15-20 parts of furfural residues, 25-30 parts of mushroom residues, 10-12 parts of rape seed cakes, 10-12 parts of sweet potato vines, 8-10 parts of peat, 12-15 parts of duck manure, 10-13 parts of sheep manure, 8-10 parts of night soil, 5-7 parts of fructus ulmi, 2-4 parts of wild carrot fruits, 15-20 parts of potassium fulvic acid, 10-15 parts of ammonium phosphate, 3-5 parts of zinc sulfate, 0.01-0.02 part of sodium selenite, 0.007-0.009 part of a rot promoter and 205-215 parts of water, wherein the rot promoter is prepared by mixing the following raw materials: iron phosphate, magnesium nitrate, ammonium sulfate, potassium sulfite and ammonium hydrogen phosphate.
