1. Ultrasonic extraction of bio-nano (ultrasonic chemical synthesis) In the ultrasonic chemical reaction, the key role is the cavitation effect of sound waves. During the irradiation of ultrasonic waves, cavitation bubbles will form, grow and collapse in the liquid. Off, when the cavitation bubble collapses, it produces a covered strong pressure pulse, which produces many unique properties, such as producing high temperatures up to 5000K, pressures greater than 200Mpa, and cooling rates up to 1010K/p, which is ultrasonic chemical synthesis. Energy source, Kcap, Okitso, etc. 0.5um oAl1/O3 powder was added to PdLN.2N3Cl.3H20 solution, and then a regulation to Pd2, reduction promotion was carried out, and then irradiated with 20Khz ultrasonic wave, in Al2O2 Pd nanoparticles of about 10 nm were synthesized on the surface.
2. Ultrasonic pharmaceutical
(1) Dispersion of pharmaceutical substances for injection - Mixing phospholipids with cholesterol by mixing with an appropriate method in an aqueous solution, and dispersing by ultrasonication, smaller particles (about 0.1 μm) can be obtained for intravenous injection.
(2) Herbal extraction - using ultrasonic dispersion to destroy plant tissue, accelerate the penetration of solvent into tissue, and improve the extraction rate of active ingredients in Chinese herbal medicine. For example, all the alkaloids in the bark of Cinchona can be invaded by the general method for more than 5 hours, and the ultrasonic dispersion can be completed in half an hour to complete the medical education network.
(3) Preparation of a suspension - a solid drug is dispersed in an aqueous solution containing a surfactant under ultrasonic cavitation and vigorous agitation to form an oral or intravenous suspension of about 1 um. Examples are "intravenous camptothecin suspension", "liver contrast agent", "barium sulfate suspension".
(4) Preparation of vaccines - After killing cells or viruses by means of ultrasonic dispersion, a vaccine is prepared by an appropriate method.
3. Ultrasonic dispersion of cosmetics
In order to further extract the essence of the drug and the micronization of the particles, and to save production costs, to achieve the dispersion and emulsification effect, the cosmetics penetrate deep into the inner layer of the skin, let the skin absorb well, exert the efficacy and effect of the drug, and adopt ultrasonic emulsification. Achieve very good results. By ultrasonic dispersion, fine particles of oil such as wax and paraffin emulsified or lotion can be dispersed without using an emulsifier. Paraffin particles dispersed in water can be up to 1um in diameter.
4. Ultrasonic alcoholization of wine - aging technology
A bottle of fine wine is mellow, soft and soft, and rich in fragrance. People often use old wine to describe the preciousness of wine. A bottle of wine from the last century is priced at tens of thousands of yuan. The price means the storage of time. . The main controlling factor of wine is the chemical change, ie the formation of acid, and further esterification, the ester is involved in the association of ethanol and water. The wine that has just been shipped contains sterols, which have a spicy taste. It takes a long time to resolve. This slow change is called alcoholization. Ultrasonic treatment with a power of 1.6KW and a frequency of 17.5~22KHZ for 5-10 minutes can shorten the ripening time of wine by 1/3 to 1/2.
