1. Ultrasonic extraction of biological nanometers

(Ultrasonic chemical synthesis method) In the ultrasonic chemical reaction, the cavitation effect of the sound wave plays a key role. During the ultrasonic irradiation process, the formation, growth and collapse of cavitation bubbles will occur in the liquid. When the cavitation bubbles collapse When it is extinguished, a strong pressure pulse is generated, which produces many unique properties, such as high temperature up to 5000K, pressure greater than 200Mpa, and cooling rate up to 1010K/p, which is the energy source of ultrasonic chemical synthesis, Kcap, Okitso Add 0.5um o.Al1/O3 powder to the PdLN.2N3Cl.3H20 solution, then add a kind of gauge that promotes the reduction of Pd2, and then irradiate with 20Khz ultrasonic waves to synthesize 10nm on the surface of Al2O2 around Pd nanoparticles.

2. Ultrasonic pharmaceutical

(1) Dispersion of pharmaceutical substances for injection - Mix phospholipids and cholesterol with drugs in an aqueous solution by appropriate methods, and disperse by ultrasonic to obtain smaller particles (about 0.1um) for intravenous injection.

(2) Extraction of herbal medicines—Using ultrasonic dispersion to destroy plant tissues, accelerate the penetration of solvents into tissues, and improve the extraction rate of effective components of Chinese herbal medicines. For example, it takes more than 5 hours for all the alkaloids in the bark of cinchona to penetrate by the general method, and it only takes half an hour to complete by ultrasonic dispersion.

(3) Preparation of suspension - under ultrasonic cavitation and strong stirring, a solid drug is dispersed in an aqueous solution containing surfactant, and a suspension of about 1um can be formed for oral or intravenous injection. Examples include "intravenous camptothecin suspension", "liver contrast agent", and "barium sulfate suspension".

(4) Preparation of vaccines - after cells or viruses are killed by ultrasonic dispersion, vaccines are prepared by appropriate methods.

3. Ultrasonic dispersion of cosmetics

In order to further extract the essence of the drug and miniaturize the particles, save the production cost, achieve the effect of dispersion and emulsification, make the cosmetics penetrate deeper into the inner layer of the skin, allow the skin to absorb well, and exert the efficacy and effect of the drug, ultrasonic emulsification can be used. achieve a very ideal effect. Ultrasonic dispersion can disperse fine particles of oils such as wax, paraffin emulsification, and lotion without using an emulsifier. The particle diameter of paraffin dispersed in water can reach below 1um.

4. Ultrasonic alcoholization of wine - aging technology

A bottle of fine wine is favored by people for its mellow taste, softness, softness and rich aroma. People often use aged wine to describe the preciousness of wine. A bottle of aged wine from the last century is priced at tens of thousands of yuan. The meaning of its price lies in the storage of time. . The main controlling factor in wine is the chemical change i.e. acid formation, and further esterification, which is involved in the association of ethanol and water. The wine that has just left the factory contains alcohol and has a spicy taste. This smell will take a long time to dissolve. This slow change is called the alcoholization of the wine. Ultrasonic treatment with a power of 1.6KW and a frequency of 17.5~22KHZ for 5~10min can shorten the aging time of wine by 1/3 to 1/2
