Li-micromotor ho hloekisa carbon dioxide maoatleng a rona

Litsebi tsa Nanoengineers tse tsoang Univesithing ea California e San Diego li entse enjene e nyenyane haholo e etselitsoeng ho ntša carbon dioxide leoatleng. Ha acidization ea maoatle a lefats'e e ntse e eketseha, ho tlosa carbon dioxide leoatleng ka tšepo ho tla fokotsa kapa ho fetola liphello tsa phetoho ea boemo ba leholimo ka nako. Maemo a phahameng a carbon dioxide metsing a fella ka ho fokotseha ha bophelo ba metsing le boleng ba metsi lefatšeng ka bophara.  

"Li-micromotor" tsena tse ncha li tla ba ka pele ho phokotso ea carbon dioxide. Mongoli oa pele oa lithuto, Virendra V. Singh, e re, “Re thabela monyetla oa ho sebelisa li-micromotor tsena ho loantša ho ata ha maoatle le ho futhumala ha lefatše.” 

Li-micromotor tsa Univesithi ea California li sebelisa enzyme e bitsoang carbonic anhydrase holim'a polima e ka ntle ho pota-pota ka metsing. E sebelisa hydrogen peroxide e le mofuta oa mafura ho matlafatsa enzyme. Hydrogen peroxide e sebetsa le bokaholimo ba polatinamo ho hlahisa lipululana tsa oksijene. Li-bubble tsena li tsamaisa carbonic anhydrase ebe li tsamaisa enjene.  

Kaha bokaholimo ba platinum bo etsa hore micromotor e be theko e phahameng, bafuputsi ba rera mokhoa oa ho etsa lienjene tse tsamaisoang ke metsi. "Haeba li-micromotor li ka sebelisa tikoloho e le mafura, li tla senyeha haholoanyane, li se ke tsa senya tikoloho 'me li fokotsehe," ho boletse joalo. Kevin Kaufmann, mongoli-'moho oa thuto.  

Enzyme ea carbonic anhydrase e boetse e sebetsa e le mokhoa oa ho fokotsa carbon dioxide metsing. E etsa joalo ka ho potlakisa karabelo pakeng tsa carbon dioxide le metsi, e fetolang carbon dioxide hore e be calcium carbonate. Calcium carbonate ka har'a ntho e etsang bongata ba likhetla tsa leoatle le lejoe la mokoetla 'me e na le botsoalle ho tikoloho.  

Micromotor e 'ngoe le e' ngoe e bolelele ba li-micrometer tse 6 'me e ikemela ka botlalo. Ha li se li kentsoe ka metsing, lia tsamaea 'me li “hloekisa” carbon dioxide leha e le efe eo li kopanang le eona. Ka lebaka la motsamao o potlakileng le o tsoelang pele oa li-motor, li sebetsa hantle haholo. Litekong tsa thuto, li-micromotor li khonne ho tsamaea ka potlako e ka bang 100 micrometer ka motsotsoana, 'me li khonne ho tlosa. 88 lekholong ea carbon dioxide ka tharollo ea metsi a leoatle ka metsotso e 5.  

Hang ha lienjene tsena tse nyenyane li kentsoe ka leoatleng, li tla tsoela pele ho tlosa carbon dioxide leha e le efe metsing le ho loantša liphello tsa phetoho ea boemo ba leholimo maoatleng a rona. Ka lehlohonolo leha e le lefe, ba ka tsosolosa bophelo bo botle ba maoatle a rona le bophelo ba metsing bo lulang ho bona.
