Ngongole yazithunzi: ACS Applied Materials and Interfaces
Akatswiri a ku yunivesite ya Massachusetts Amherst apanga ansaluzomwe zimakupangitsani kutentha pogwiritsa ntchito nyali zamkati.Ukadaulowu ndi wotsatira wazaka 80 zofunafuna kupanga nsalu kutengera chimbalangondo cha polarubweya.Kafukufukuyu adasindikizidwa mu nyuzipepala ya ACS Applied Materials and Interfaces ndipo tsopano yapangidwa kukhala chinthu chamalonda.
Zimbalangondo za polar zimakhala m'malo ovuta kwambiri padziko lapansi ndipo sizimatenthedwa ndi kutentha kwa Arctic komwe kumatsika mpaka 45 digiri Celsius.Ngakhale kuti zimbalangondo zimakhala ndi zosintha zingapo zomwe zimazilola kuti ziziyenda bwino ngakhale kutentha kutsika, asayansi akhala akuyang'ana kwambiri kusinthasintha kwa ubweya wawo kuyambira m'ma 1940.Kodi chimbalangondo cha polar chimayenda bwanjiubweyakutenthetsa?
Nyama zambiri za ku polar zimagwiritsa ntchito kuwala kwa dzuŵa kuti zisunge kutentha kwa thupi lawo, ndipo ubweya wa zimbalangondo ndi chitsanzo chodziwika bwino.Kwa zaka zambiri, asayansi adziwa kuti mbali ina ya chinsinsi cha zimbalangondozi ndi ubweya wawo woyera.Amakhulupirira kuti ubweya wakuda umayamwa kutentha bwino, koma ubweya wa chimbalangondo watsimikizira kuti ndi wothandiza kwambiri kusamutsa kuwala kwa dzuwa pakhungu.
Chimbalangondo cha polarubweyakwenikweni ndi ulusi wachilengedwe umene umachititsa kuwala kwa dzuwa pakhungu la chimbalangondo, chomwe chimatenga kuwala ndi kutentha chimbalangondo.Ndipo theubweyaimathandizanso kwambiri kuteteza khungu lofunda kuti lisatulutse kutentha konseko kovutirako.Dzuwa likawalira, zimakhala ngati kukhala ndi bulangeti lochindikala kuti mutenthetse thupi lanu ndi kusunga kutentha pakhungu lanu.
Gulu lofufuza linapanga nsalu yamitundu iwiri yomwe pamwamba pake imakhala ndi ulusi womwe, ngati chimbalangondo cha polarubweya, yendetsani kuwala kowonekera kumunsi, komwe kumapangidwa ndi nayiloni ndipo yokutidwa ndi zinthu zakuda zotchedwa PEDOT.PEDOT imagwira ntchito ngati chimbalangondo cha polar kuti isunge kutentha.
Jekete yopangidwa kuchokera kuzinthu izi ndi 30% yopepuka kuposa jekete la thonje lomwelo, ndipo mawonekedwe ake opepuka komanso otentha amagwirira ntchito bwino kuti atenthetse thupi mwachindunji pogwiritsa ntchito kuyatsa komwe kuli m'nyumba.Pogwiritsa ntchito mphamvu zamagetsi kuzungulira thupi kuti apange "nyengo yaumwini", njirayi ndi yokhazikika kuposa njira zomwe zilipo kale zotentha ndi kutentha.
