Ubuki butemba vuba kurusha amazi muri capillaries zidasanzwe

Urakoze kwiyandikisha kwisi yumubiri Niba ushaka guhindura amakuru yawe umwanya uwariwo wose, nyamuneka sura konti yanjye
Ubuki hamwe nandi mazi menshi cyane afite umuvuduko mwinshi kurusha amazi muri capillaries zometseho umwihariko.Ubushakashatsi butangaje bwakozwe na Maja Vuckovac na bagenzi be bo muri kaminuza ya Aalto yo muri Finlande, nabo berekanye ko izo ngaruka ziterwa no guhagarika umuvuduko wimbere mu bitonyanga byinshi.
Umwanya wa microfluidics urimo kugenzura umuvuduko wamazi unyuze mu turere dufunze cyane twa capillaries - mubisanzwe mugukora ibikoresho byokoreshwa mubuvuzi. Hasi ya viscosity fluid nibyiza kuri microfluidics kuko itemba vuba kandi bitagoranye. Amazi menshi yimitsi ashobora gukoreshwa mukuyatwara kumuvuduko mwinshi, ariko ibyo bishobora gutera kunanirwa muburyo bwa capillary - bishobora gutera kunanirwa.
Ubundi, umuvuduko urashobora kwihuta ukoresheje igifuniko cya superhydrophobique kirimo micro- na nanostructures zifata imitego yo mu kirere.Iyi misego igabanya cyane aho ihurira hagati y’amazi n’ubuso, ari nako bigabanya ubushyamirane - kwiyongera gutemba kuri 65% .Nyamara, ukurikije ibitekerezo biriho, ibi bipimo bikomeza kugabanuka hamwe no kwiyongera kwijimye.
Itsinda rya Vuckovac ryagerageje iki gitekerezo bareba ibitonyanga byijimye bitandukanye kuko uburemere bwabakuye muri capillaries vertical hamwe na superhydrophobique yimbere yimbere.Nkuko bagenda kumuvuduko uhoraho, ibitonyanga bikanda umwuka munsi yabyo, bigatera umuvuduko ukabije ugereranije nu muri piston.
Mugihe ibitonyanga byerekanaga isano iteganijwe hagati yubukonje nigipimo cyogutemba mumiyoboro ifunguye, mugihe impera imwe cyangwa zombi zafunzwe, amategeko yarahinduwe rwose.Ingaruka yagaragaye cyane hamwe nigitonyanga cya glycerol-nubwo amabwiriza 3 yubunini afite ubwiza burenze amazi, yatembaga inshuro zirenga 10 kurenza amazi.
Kugirango ugaragaze physics iri inyuma yizi ngaruka, itsinda rya Vuckovac ryinjije uduce duto twa tracer mu bitonyanga.Igikorwa cyuduce twagiye tugaragaza igihe cyihuta cyimbere mu gitonyanga kitagaragara neza.Iyi migezi itera amazi kwinjira mumiterere ya micro- na nano-nini mubipfundikizo.Ibyo bigabanya umubyimba wumuvuduko ukabije wumuvuduko ukabije wumuvuduko ukabije. gutemba, kubuza kwinjira kwayo. Ibi bivamo umwuka mwinshi mwinshi, byorohereza umwuka munsi yigitonyanga kwimuka kuruhande rumwe.
Bakoresheje ibyo babonye, ​​itsinda ryashyizeho uburyo bwa hydrodynamic bugezweho bwerekana neza uburyo ibitonyanga binyura muri capillaries hamwe na superhydrophobique itandukanye. Hamwe nakazi keza, ubushakashatsi bwabo bushobora gutuma habaho uburyo bushya bwo gukora ibikoresho bya microfluidic bishobora gukoresha imiti n’ibiyobyabwenge bigoye.
Physics World yerekana igice cyingenzi mubutumwa bwa IOP Publishing bwo kumenyekanisha ubushakashatsi no guhanga udushya ku isi ku bantu benshi bashoboka.Urubuga ni igice cya portfolio yisi ya fiziki, gitanga icyegeranyo cya serivisi zamakuru kuri interineti, imibare n’icapiro ku bumenyi bwa siyansi ku isi.
