Micromotors na-asachapụ carbon dioxide n'oké osimiri anyị

Ndị injinia Nanoengine na Mahadum California dị na San Diego emepụtala moto a na-ahụ anya nke e mere iji wepụ carbon dioxide n'oké osimiri. Site na acidification nke oke osimiri nke ụwa na-abawanye, iwepụ carbon dioxide n'oké osimiri ga-atụ anya ibelata ma ọ bụ gbanwee mmetụta mgbanwe ihu igwe na oge. Ọkwa dị elu nke carbon dioxide na mmiri na-ebute mbelata nke ndụ mmiri na ịdị mma mmiri n'ụwa niile.  

Ndị "micromotors" ọhụrụ a ga-anọ n'isi njedebe na mbelata carbon dioxide. Onye edemede nke mbụ, Virendra V. Singh, na-ekwu, "Obi dị anyị ụtọ maka ohere nke iji micromotor ndị a lụso acid dị n'oké osimiri ọgụ na okpomoku zuru ụwa ọnụ." 

Micromotors nke Mahadum California na-eji enzyme akpọrọ carbonic anhydrase na polymer dị n'èzí na-agagharị na mmiri. Ọ na-eji hydrogen peroxide dị ka ụdị mmanụ ọkụ iji mee ka enzyme ahụ dị ike. Mmiri hydrogen peroxide na-emeghachi omume na elu platinum dị n'ime iji mepụta ikuku oxygen. Afụ ndị a n'aka nke na-ebuli carbonic anhydrase ma bugharịa moto.  

N'ihi na elu nke platinum na-eme ka micromotor dị oke ọnụ, ndị nchọpụta na-eme atụmatụ maka ụzọ isi mee ka moto na-ebugharị site na mmiri. "Ọ bụrụ na micromotors nwere ike iji gburugburu ebe obibi dị ka mmanụ ụgbọala, ha ga-adịkwu ike, enyi na gburugburu ebe obibi na obere ọnụ," kwuru. Kevin Kaufmann, onye na-ede akwụkwọ.  

Carbonic anhydrase enzyme na-arụkwa ọrụ dị ka ụzọ isi belata carbon dioxide n'ime mmiri. Ọ na-eme nke a site n'ime ka mmeghachi omume dị n'etiti carbon dioxide na mmiri dị ngwa, nke na-eme ka carbon dioxide ghọọ calcium carbonate. Calcium carbonate dị n'ime ihe na-emeju oke oke osimiri na nkume nzu ma bụrụ enyi na gburugburu ebe obibi.  

Micromotor ọ bụla bụ 6 micrometers ogologo ma nwee onwe ya kpamkpam. Ozugbo etinyere ya na mmiri, ha na-aga n'ihu wee "na-ehichapụ" carbon dioxide ọ bụla ha hụrụ. N'ihi ngwa ngwa na-aga n'ihu na-aga n'ihu nke moto, ha na-arụ ọrụ nke ọma. N'ime nyocha nke ọmụmụ ahụ, micromotors nwere ike ịkwaga ngwa ngwa dị ka 100 micrometer kwa nkeji, ma nwee ike iwepụ. 88% nke carbon dioxide na mmiri mmiri mmiri ngwọta na 5 nkeji.  

Ozugbo a na-etinye obere moto ndị a n'oké osimiri, ha ga-anọgide na-ewepụ carbon dioxide ọ bụla n'ime mmiri ma luso mmetụta nke mgbanwe ihu igwe na oke osimiri anyị ọgụ. Na chioma ọ bụla, ha nwere ike iweghachi ahụike nke oke osimiri anyị na ndụ mmiri nke bi na ha.
