Uphononongo luchaza inoveli ephathekayo yelanga-inkqubo yokuqokelela i-steaming kunye ne-polymer origami enokuthi iqokelele kwaye ihlambuluke amanzi ngexabiso eliphantsi kakhulu
Kukho imfuno ekhulayo yehlabathi yokucoceka amanzi ngenxa yokwanda kwabemi, ukukhula kwemizi-mveliso kunye nokungcoliseka kunye nokuncipha koluntu lwethu iiplanethi Uvimba wendalo. solar-ukuphunga bubuchule apho Amandla esola ingasetyenziselwa ukucoca amanzi ngokuba ngumphunga ungcolisekile amanzi, ukuyijiya kwakhona kwaye ivelise icocekile entsha amanzi. Obu buchwephesha bubuchwephesha obucocekileyo, obunokuhlaziywa kwaye buzinzileyo obuluhlaza obunamandla okujongana nokunqongophala kwamanzi acocekileyo kwihlabathi ngokusebenzisa ubuninzi bomhlaba. yelanga amandla. Amandla kunye nokusebenza kakuhle kwe yelanga-i-steaming system ixhomekeke kuyilo lwayo kunye nokukhethwa kwezinto eziphathekayo ze-photothermal. Okwangoku yelanga-Ubuchwephesha bokuphunga busebenzisa izinto ezibizayo, ezinkulu kwaye zinokusebenza okuphantsi kunye nemveliso encinci. Kuye kwahlala kungumngeni wokuphucula ukusebenza kunye neendleko eziphantsi ukwenzela ukuyila ubunzima obulula kunye nokuphathekayo yelanga-inkqubo yokuphefumula enokuthi isetyenziswe ngokuthe ngqo ngabantu.
Kuphononongo olutsha olupapashwe ngoMeyi 28 ngo Izinto eziphambili abaphandi bachaza indlela entsha ye yelanga ukuphunga ngokuyila ixabiso eliphantsi eliphathwayo elinoxinzelelo oluphantsi olulawulwayo yelanga inkqubo yokuqokelela umphunga enokuqokelela kwaye ihlambuluke amanzi usebenzisa amandla avela kukukhanya kwelanga. Bakhetha i-photothermal polymer material ebizwa ngokuba yiPolypyrrole (PPy) eqhubayo kwindalo, eyaziwayo ngeempawu zayo ze-photothermal kwaye ibonisa ukusebenza kakuhle okuphezulu ekuguquleni ukukhanya kwelanga kubushushu obushushu. Iphefumlelwe ukusuka kwintyatyambo yentyatyambo, uyilo olukhethekileyo lwale nkqubo ye-solar steaming system yenziwe nge-3D origami PPy-paper composite. 'I-PPy rose' equka amashiti amnyama anomaleko amile okweepetali adalwe ngokusongwa kwe-origami kunye ne-polymerization yekhemikhali yePPy. Esi sakhiwo se-origami sifakwe kwi-tube efana ne-cotton efakwe kwi-stem eqokelela amanzi ahlaza / angaphendulwanga kumthombo wamanzi kwaye uyondla kwisakhiwo se-PPy rose esibekwe phezulu. I-cotton efakwe ityhubhu kunye ne-Polystyrene foam yayisetyenziselwa ukuthintela ukudibanisa ngokuthe ngqo phakathi kwezinto zePPy kunye namanzi amaninzi.
Xa ingaphathwanga amanzi ifikelele kwiipetals, izinto zePPy kwisakhiwo seentyatyambo sijika amanzi ibe ngumphunga kunye nokungcola okwahlukileyo ngokwendalo emanzini. Emva koko, umphunga wamanzi ufuna ukucuthwa kwaye emva koko kufuneka kuqokelelwe amanzi acocekileyo ukuze asetyenziswe. Abaphandi basebenzise imeko yoxinzelelo oluphantsi ngokusebenzisa ipompo yokucoca ephathwayo. Oku kwabonwa njengokunyusa kakhulu amazinga okuphuma kwamanzi abe ngumphunga kunye nokuqokelelwa kwamanzi. Akuba amanzi ejingisiwe, ingqayi yeglasi eqokelelweyo neyomeleleyo igcina amanzi acocekileyo ngokukhuselekileyo.
I-origamis ye-3D ibonelele ngokugqithiswa okuphezulu kokukhanya kunye neendawo eziphuculweyo eziphezulu amanzi ukuguquka kwamanzi xa kuthelekiswa noyilo oluqhelekileyo lwe-2D lweplani. Umphunga wamanzi kunye nezinga lokuqokelela liphuculwe ngama-52 ekhulwini ngenxa yokuhla koxinzelelo lwegumbi. I-PPy origami iphucule ukuphuphuma kwamanzi ngama-71 ekhulwini kunye namazinga aphezulu okuqokelela umphunga nawo abonwa. Ukusebenza ngokubanzi kwenkqubo kwanda ngeepesenti ze-91.5 phantsi komthombo omnye wokukhanya. Inkqubo yavavanywa kwisampulu evela kumlambo waseColorado eTexas, eU.SA. Inkqubo yasusa ukungcoliseka kwamanzi ngendlela yesinyithi esinzima, ibhaktheriya, ityuwa kunye nokunciphisa i-alkalinity evelisa amanzi acocekileyo omgangatho wokusela njengoko kumiselwe yi-WHO.
Uphononongo lwangoku luchaza uyilo olunengqiqo lwenoveli yenkqubo yokuqokelela i-solar-steaming ephathekayo enexabiso eliphantsi kunye ne-3D origami photothermal materials enika amaxabiso aphuculweyo okuphuma kwamanzi kunye nokuqokelela umphunga. Iindleko zesakhiwo ngasinye esifana nentyatyambo ingaphantsi kweesenti ezi-2 kwaye inokuvelisa ngempumelelo iilitha ezi-2 zamanzi acocekileyo ngeyure nganye kwisikwere semitha. Olu luyilo lunokuba yinkuthazo yokwenza iimodeli ezizodwa zokutshisa i-solar-steaming kwimveliso yamanzi acocekileyo.
