Ultrasonic tau dhau los ua ib qho kev tshawb fawb hotspot nyob rau hauv lub ntiaj teb no vim nws ntau lawm nyob rau hauv huab hwm coj hloov, hloov tshav kub thiab tshuaj tiv thaiv.Nrog rau kev txhim kho thiab nrov ntawm cov cuab yeej siv hluav taws xob ultrasonic, qee qhov kev nce qib tau ua hauv industrialization hauv Europe thiab Amelikas.Kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis hauv Suav teb tau dhau los ua kev sib koom tes tshiab - sonochemistry.Nws txoj kev loj hlob tau cuam tshuam los ntawm kev ua haujlwm zoo hauv kev xav thiab kev siv.

Qhov hu ua ultrasonic nthwv dej feem ntau yog hais txog acoustic nthwv dej nrog ntau zaus ntawm 20k-10mhz.Nws daim ntawv thov lub zog nyob rau hauv cov tshuaj teb mas yog los ntawm ultrasonic cavitation.Nrog muaj zog shock yoj thiab microjet nrog tshaj tawm siab tshaj 100m / s, lub siab gradient shear ntawm shock yoj thiab microjet tuaj yeem tsim hydroxyl radicals hauv cov kua dej.Cov teebmeem ntawm lub cev thiab tshuaj lom neeg feem ntau yog cov teebmeem ntawm cov khoom siv (acoustic shock, shock yoj, microjet, thiab lwm yam), thermal teebmeem (lub zos kub thiab kub siab, tag nrho cov kub nce), optical teebmeem (sonoluminescence) thiab ua kom muaj teebmeem (hydroxyl radicals yog. tsim nyob rau hauv aqueous tov).Plaub qhov teebmeem tsis raug cais tawm, Xwb, lawv sib cuam tshuam thiab txhawb ib leeg kom ceev cov txheej txheem tshuaj tiv thaiv.

Tam sim no, kev tshawb fawb ntawm daim ntawv thov ultrasound tau ua pov thawj tias ultrasound tuaj yeem qhib lub hlwb thiab txhawb cov metabolism.Tsawg siv ultrasound yuav tsis ua kom tag nrho cov qauv ntawm tes, tab sis nws muaj peev xwm txhim khu cov metabolic kev ua ntawm lub cell, nce permeability thiab selectivity ntawm cell membrane, thiab txhawb lub lom catalytic kev ua si ntawm lub enzyme.Lub siab siv ultrasonic nthwv dej tuaj yeem ua rau cov enzymes, ua kom cov colloid nyob rau hauv lub cell undergo flocculation thiab sedimentation tom qab muaj zog oscillation, thiab liquefy los yog emulsify lub gel, yog li ua rau cov kab mob tsis ua hauj lwm lom.Ntxiv rau.Qhov kub thiab txias tam sim ntawd, qhov kub thiab txias hloov, lub siab ceev ceev thiab lub siab hloov pauv tshwm sim los ntawm ultrasonic cavitation yuav tua qee cov kab mob hauv cov kua, inactivate tus kab mob, thiab txawm rhuav tshem cov phab ntsa ntawm tes ntawm qee cov kab mob me me.Kev siv ultrasound ntau dua tuaj yeem rhuav tshem cov phab ntsa ntawm tes thiab tso cov tshuaj hauv lub cell.Cov teebmeem lom no kuj muaj feem xyuam rau cov nyhuv ntawm ultrasound ntawm lub hom phiaj.Vim qhov tshwj xeeb ntawm algal cell qauv.Kuj tseem muaj cov txheej txheem tshwj xeeb rau kev tshem tawm cov algae ultrasonic thiab tshem tawm, uas yog, lub hnab cua hauv cov algal cell siv los ua cov cavitation nucleus ntawm cov cavitation npuas, thiab lub hnab cua tau tawg thaum lub cavitation npuas tawg, uas ua rau lub cavitation npuas. algal cell poob lub peev xwm los tswj floating.
