Ngwa nke Ultrasonic Sonochemistry na Nkwadebe Nanomaterial

Mmetụta Cavitation

Mkpọtụ ugboro ugboro nke sitere na ultrasonic na-agbasa n'ime mmiri na-eme ka cavitation dị elu, na-emepụta afụfụ nha micron nke na-ada ngwa ngwa, na-ewepụta oke okpomọkụ na nrụgide mpaghara. Gburugburu ebe siri ike a na-eme ka mmeghachi omume kemịkalụ dị ngwa ngwa, ebe microjets ndị na-esote na-akwalite mgbasa nanoparticle ma na-egbochi njikọta.

Mmetụta Mmekọrịta nke Mmetụta Mechanical na Thermal

Mkpọtụ igwe nke ultrasonic na-eme ka arụmọrụ ngwakọta nke ihe ndị na-emeghachi omume dịkwuo mma, ebe okpomọkụ sitere na cavitation na-ebelata ike mkpali nke mmeghachi omume ahụ. Dịka ọmụmaatụ, na mbelata mmiri mmiri enyere aka na ultrasound, nhọrọ nnu ọla na-ebelata ngwa ngwa ka ọ bụrụ nanoparticles ígwè n'okpuru cavitation, na-ebute nkesa ihe ndị na-adịghị agbanwe agbanwe.

Ugbu a, a na-eji ụlọ pụrụ iche nke ultrasound sonochemistry eme ihe na njikọ nke ọtụtụ ihe nanoscale: alloys ígwè, oxides, sulfides, ihe carbon, biomaterials, wdg.

Dịka ọmụmaatụ, lee ihe atụ nke silicon polycrystalline:

1. Mgbasa dị elu na mbufe oke ka mma: Ebili mmiri ultrasonic na-emepụta afụ cavitation na mmiri mmiri site na mkpọtụ ugboro ugboro. Gburugburu okpomọkụ dị elu na nrụgide dị elu nke e tinyere na afụ crumple na-agbaji ngwakọta nke ihe ndị dị na ya nke ọma. Na ọkwa njikọta silicon polycrystalline, mmetụta a na-eme ka usoro mgbanwe oke nke mmeghachi omume silane dị ngwa ngwa, na-amụba chajị deposition silicon polycrystalline site na iji ihe karịrị 30%, ebe ọ na-egbochi mmepụta nke ngwaahịa silicon amorphous ma na-eme ka ịdị ọcha kristal dịkwuo mma nke ukwuu.
2. Nhazi arụmọrụ zuru oke nke ihe onwunwe: Na usoro ịchacha kemịkalụ ma ọ bụ nhicha, mmetụta cavitation na-eme ka otu nzaghachi dịkwuo mma, na-ebelata obere mgbawa ma na-emerụ oyi akwa na elu wafer silicon, si otú a na-eme ka arụmọrụ mgbanwe fotoelectric nke sel fotovoltaic dịkwuo mma. Na nkwadebe nanomaterial, ike ultrasonic nwere ike ijikwa nha na nkesa nke ihe nano-silicon, na-egbochi njikọta ma na-ahụ na conductivity ha na nkwụsi ike ha na slurries electrode ma ọ bụ ihe mejupụtara.
3. Mmetụta na Mbelata Uru: Mmetụta gabigara ókè nke ultrasonic sonochemistry n'otu oge na-ebelata usoro mmepụta. Usoro nhicha ma ọ bụ ịcha ihe ọdịnala nke na-ewe awa ole na ole nwere ike ime ka ọ dị mkpụmkpụ ruo nkeji iri site na enyemaka ultrasonic, na-ebelata oriri ike site na ihe karịrị 40%. Na nkwadebe mado, ọrụ mgbasa ngwa ngwa ya na-eme ka ikesa nke ihe na-agba ọsọ na nkesa nke ihe mkpuchi ọlaọcha ma ọ bụ aluminom dịkwuo mma, na-ebelata ntụpọ mbipụta, ma na-eme ka ike eletrik dịkwuo mma. Ọzọkwa, ngwaọrụ ahụ na-ebelata ọnụ ahịa ọgwụgwọ gburugburu ebe obibi site na ibelata ojiji nke ihe ndị na-emepụta kemịkalụ na mwepụ mmiri mkpofu.

Sonochemistry ultrasonic FUNSONIC na-enweta ihe karịrị otu uru na omume silicon polycrystalline site na mgbasa ozi na-adịghị ize ndụ gburugburu ebe obibi, mmụba cavitation, na njikwa pụrụ iche, dị ka ihe onwunwe agbatịkwuru, arụmọrụ sistemụ kachasị mma, na mbelata ọnụ ahịa gburugburu ebe obibi. Ọ na-ekpughe uru pụrụ iche, karịsịa na njikọta, mgbasa, na ọrụ nke nanoparticles. Site na mmepe teknụzụ na-akwụsị akwụsị na njikarịcha ngwaọrụ, ikike ojiji ya na ike ọhụrụ, nchedo gburugburu ebe obibi, na biomedicine ga-eto ka ọ dịkwuo ukwuu.
