Iibhola ze-hydrogel ziyakwazi ukufumana amanzi amawaka ngaphezulu kobunzima bayo, kubonakala ngathi ziyilungele ukusetyenziswa kweetanki ezincinci ezingaphantsi komhlaba. Ithiyori, xa umhlaba uyomisa, i-hydrogels amanzi ayodwa ukuya kwi-hydrate i-hydrate i-viet yezityalo, ngaloo ndlela isonga amanzi kunye nokukhulisa imeko yezityalo nakwezinye iimeko zembalela.
Nangona kunjalo, ukongezwa kwee-hydrogels kwiMimandla yamaFama inika iziphumo zokubi.
Kumsebenzi wakhe, izazinzulu zePrinceton zibonakalise iqonga lovavanyo. Ikuvumela ukuba uqaphele i-hydrogals kwimihlaba, kunye nakwezinye iindawo ezinyanzelisiweyo.
Iqonga lisekwe kwizithako ezimbini: I-Granterium ye-Granular ebonakalayo, eqaqambileyo yeebhola zeglasi, njengendawo yomhlaba, kunye namanzi anemichiza, ebizwa ngokuba yi-Ammobyanate. Le michiza itshintshe ngobuchule ukucocwa kokukhanya ngamanzi, kubuyisela iziphumo ezigqwethekileyo ezinokuthi zibe neebhulukhwe zeglasi. Ngenxa yoko, izazinzulu zinokubona ibhola ye-hydrogel ye-hydrogel embindini womhlaba ofanelekileyo.
"Ukuziqhelanisa nelabhoratoring kukukhangela kweekhemikhali ezinqwenelekayo kugxininiso lwezinto ezinqabileyo ukutshintsha iipropathi zotywala," utshilo i-chameta yobuqhophololo kwiPrinceton kunye noMbhali oPhakathi oshicilelweyo kwiNzululwazi yejenali Inkqubela phambili nge-12 kaFebruwari. - Eli nqaku linika umbono obonakalayo weendlela ezintathu zokuhamba kwamanzi kunye nezinye iinkqubo ezenzeka kwiindawo ezihlala zingafikelelekiyo, ezikwi-opaque iimeko ezifana nomhlaba kunye namatye.
Izazinzulu zisebenzise ufakelo ukubonisa ukuba ubungakanani bamanzi agcinwe yi-hydrogels ilawulwa yimali esezantsi phakathi kwamandla e-hydrogel eqhotyoshelwe amanzi kunye nokuthintela umhlaba.
Ngenxa yoko, i-hydrogels ethambileyo ithathe inani elikhulu lamanzi xa uxubana namanzi omhlaba, kodwa ungasebenzi kakuhle kubunzulu obuthile, apho uxinzelelo olukhulayo lujamelana nalo.
Endaweni yoko, qinisa i-hydrogels engqongqo, ihambelane nokunyuka kwamanqaku angaphakathi anqamlezileyo, unokungcono ngakumbi kuxinzelelo lomhlaba kwaye, ngokufanelekileyo, bagcina impumelelo.
I-DATTA yatsho ukuba, kukhokelwe kwezi ziphumo, iinjineli ngoku ziya kuba nakho ukuqhuba ezinye iimvavanyo zokutshintsha i-chemistry ye-hydrogels kwiinkcubeko ezithile kunye neemeko zomhlaba.
"Iziphumo zethu zibonelela ngeengcebiso zokuphuhliswa kwee-hydrogels ezinokuthi zifumane amanzi ngokuxhomekeka kumhlaba ekusetyenzwa kuyo, ekuncedeni ukwanelisa imfuno yokutya namanzi, utshilo i-dota.
Umthombo wokuphefumlelwa komsebenzi wesayensi kukuba i-DATT ifunyenwe malunga nethemba elikhulu lokusebenzisa i-hydroguls kwezolimo, kodwa kwezinye iimeko amafama ahlala engonelisekanga kwaye ekholelwa ukuba bachitha imali ngelize.
