Ikhredithi yesithombe: I-ACS Applied Materials and Interfaces
Onjiniyela baseNyuvesi yaseMassachusetts Amherst basungule i-indwangulokho kukugcina ufudumele usebenzisa izibani zasendlini. Ubuchwepheshe buwumphumela womzamo weminyaka engu-80 wokuhlanganisa izindwangu ngokusekelwe kubhere elimhlopheuboya. Ucwaningo lwashicilelwa kujenali ACS Applied Materials and Interfaces futhi manje seluthuthukisiwe lwaba umkhiqizo wezohwebo.
Amabhere amhlophe ahlala kwezinye zezindawo ezinokhahlo emhlabeni futhi awakhathazwa amazinga okushisa ase-Arctic aphansi aze afike ku-45 degrees Celsius. Nakuba amabhere enenani lokuzivumelanisa nezimo eziwavumela ukuba achume ngisho nalapho amazinga okushisa ehla, ososayensi bebelokhu benaka ngokukhethekile ukuguquguquka koboya bawo kusukela ngawo-1940. Linjani ibhere elimhlopheuboyaigcine ifudumele?
Izilwane eziningi ezimhlophe zikusebenzisa ngentshiseko ukukhanya kwelanga ukuze zilondoloze izinga lokushisa lomzimba wazo, kanti uboya bebhere elimhlophe buyisibonelo esaziwayo. Sekungamashumi eminyaka ososayensi bazi ukuthi ingxenye yemfihlo yamabhere uboya bawo obumhlophe. Ngokuvamile kunenkolelo yokuthi uboya obumnyama bubamba ukushisa kangcono, kodwa uboya bebhere elimhlophe bubonakale busebenza kahle kakhulu ekudluliseleni imisebe yelanga esikhumbeni.
Ibhele elihlala kwiqhwauboyaiwucu lwemvelo oluyisa ukukhanya kwelanga esikhumbeni sebhere, esimunca ukukhanya futhi sishise ibhere. Futhi iuboyafuthi kuhle kakhulu ekuvimbeleni isikhumba esifudumele ekukhipheni konke lokho kushisa okuwine kanzima. Lapho ilanga libalele, kufana nokuba nengubo yokulala ewugqinsi ukuze uzifudumeze bese ubamba ukufudumala esikhumbeni sakho.
Ithimba labacwaningi liklame indwangu enezingqimba ezimbili ungqimba wayo ongaphezulu oqukethe imicu efana nebhere elimhlopheuboya, hambisa ukukhanya okubonakalayo kungqimba olungezansi, olwenziwe ngenayiloni futhi lumbozwe ngezinto ezinombala omnyama okuthiwa i-PEDOT. I-PEDOT yenza njengesikhumba sebhere elimhlophe ukuze igcine imfudumalo.
Ijakhethi elenziwe ngale nto lilula ngo-30% kunejakhethi kakotini efanayo, futhi isakhiwo salo esibamba ukukhanya nokushisa sisebenza kahle ngokwanele ukushisisa umzimba kusetshenziswa ukukhanya okukhona kwangaphakathi. Ngokugxilisa izinsiza zamandla emzimbeni wonke ukudala "isimo sezulu somuntu siqu", le ndlela iyasimema kunezindlela ezikhona zokushisa nokufudumala.
