Urakoze kwiyandikisha muri Physical World Niba wifuza guhindura amakuru yawe igihe icyo ari cyo cyose, sura konti yanjye
Ubuki n'ibindi bintu bitonyanga cyane bitemba vuba kurusha amazi mu mitsi ipfutse neza. Ibi byavumbuwe bitangaje na Maja Vuckovac na bagenzi be bo muri Kaminuza ya Aalto muri Finlande, nabo bagaragaje ko iyi ngaruka mbi ituruka ku guhagarika urujya n'uruza rw'imbere mu bitonyanga byinshi bitonyanga. Ibisubizo byabo bihabanye neza n'ingero zigezweho z'uburyo ibitonyanga bitemba mu mitsi itonyanga cyane.
Urwego rwa microfluidics rukubiyemo kugenzura urujya n'uruza rw'amazi mu bice by'imitsi ifunganye cyane—ubusanzwe mu gukora ibikoresho byo kwa muganga. Amazi afite viscosity nke ni meza kuri microfluidics kuko atemba vuba kandi nta nkomyi. Amazi menshi afite viscosity ashobora gukoreshwa uyakoresha ku muvuduko mwinshi, ariko ibi byongera umuvuduko wa mekanike mu mitsi yoroshye—bishobora gutuma ananirwa.
Ubundi buryo, amazi ashobora kwihutishwa hakoreshejwe irangi rito ridafite amazi rigizwe n’uduce duto n’utundi duto dufata imiyoboro y’umwuka. Iyi miyoboro igabanya cyane aho amazi n’ubuso bihurira, ibyo bigatuma amazi agabanuka - bikongera amazi ku kigero cya 65%. Ariko, dukurikije inyigisho iriho ubu, iyi miyoboro y’amazi ikomeza kugabanuka uko amazi agenda yiyongera.
Itsinda rya Vuckovac ryagerageje iki gitekerezo rireba ibitonyanga by’ubushyuhe butandukanye uko imbaraga rukuruzi zabikuraga mu mitsi ihagaze ifite utwenge tw’imbere duto cyane. Uko bigenda ku muvuduko uhoraho, ibitonyanga bikanda umwuka uri munsi yabyo, bigatuma habaho umuvuduko umeze nk’uwo muri piston.
Nubwo ibitonyanga byagaragaje isano yari iteganijwe hagati y’ubushyuhe n’umuvuduko w’amazi mu miyoboro ifunguye, iyo impera imwe cyangwa zombi zafungwaga, amategeko yarahindutse burundu. Ingaruka zagaragaye cyane ku bitonyanga bya glycerol—nubwo byarushaga amazi uburebure butatu, byarushaga amazi kwihuta inshuro zirenga 10.
Kugira ngo hamenyekane imiterere y’iyi ngaruka, itsinda rya Vuckovac ryinjiye mu tunyangingo tw’uduce duto. Uko ibihe byagiye bihita byagaragaje ko imbere hatembera vuba mu kantu gato katose. Utu tunyangingo dutuma amazi yinjira mu miterere mito n’iciriritse iri mu gipfundikizo. Ibi bigabanya ubugari bw’umusego w’umwuka, bikabuza umwuka ufite igitutu munsi y’umusego kwinjiramo kugira ngo ungane n’umuvuduko w’umuvuduko. Mu buryo bunyuranye, glycerine nta rujya n’uruza rw’imbere rugaragara, bikayibuza kwinjira mu gipfundikizo. Ibi bituma umusego w’umwuka uba munini, bigatuma byoroha ko umwuka uri munsi y’igipfundikizo ujya ku ruhande rumwe.
Bakoresheje ibyo babonye, ​​itsinda ryakoze icyitegererezo gishya cya hydrodynamic gisobanura neza uburyo ibitonyanga binyura mu mitsi y'amaraso ifite irangi ritandukanye riterwa n'amazi menshi. Hamwe n'ibindi bikorwa, ibyo babonye bishobora gutuma habaho uburyo bushya bwo gukora ibikoresho bito bito bishobora gufata imiti n'imiti bigoye.
Physics World ni igice cy'ingenzi cy'intego ya IOP Publishing yo kugeza ubushakashatsi n'udushya ku rwego rw'isi ku bantu benshi bashoboka. Uru rubuga ni kimwe mu bigize urutonde rwa Physics World, rutanga icyegeranyo cya serivisi z'amakuru kuri interineti, kuri interineti no ku icapiro ku muryango w'abahanga mu bya siyansi ku isi.
