UNIVERSITY PARK, Pennsylvania — Amafasitela acwebezeliswe kabili afakwe ungqimba lomoya ovikelayo anganikeza amandla amakhulu kunamafasitela anefasitelana elilodwa, kodwa ukufaka esikhundleni samafasitela anefasitelana elilodwa akhona kungase kubize noma kube inselele yobuchwepheshe.Inketho eyonga kakhulu, kodwa engasebenzi kahle ukuvala amafasitela anegumbi elilodwa ngefilimu yensimbi ekhanyayo, emunca ukushisa kwelanga ebusika ngaphandle kokuphazamisa ukukhanya kwengilazi.Ukuze kuthuthukiswe ukusebenza kahle kokumboza, abacwaningi basePennsylvania bathi i-nanotechnology ingasiza ukuletha ukusebenza okushisayo kulingane namawindi acwebezeliswe kabili ebusika.
Ithimba elivela eMnyangweni Wezobunjiniyela Bezakhiwo wasePennsylvania liphenye izici zokonga amandla zama-coatings aqukethe izingxenye ze-nanoscale ezinciphisa ukulahlekelwa ukushisa futhi zimunce kangcono ukushisa.Baphinde baphothula ukuhlaziya kokuqala okuphelele kokusebenza kahle kwamandla ezinto zokwakha.Abacwaningi bashicilele abakutholile ku-Energy Conversion and Management.
NgokukaJulian Wang, uprofesa ohlangene wobunjiniyela bezakhiwo, ukukhanya okuseduze kwe-infrared - ingxenye yokukhanya kwelanga abantu abangakwazi ukuyibona kodwa abangakuzwa ukushisa - kungenza kusebenze umphumela oyingqayizivele we-photothermal we-nanoparticles ethile yensimbi, okwandisa ukugeleza kokushisa ngaphakathi.ngefasitela.
“Sinentshisekelo yokuqonda ukuthi le miphumela ingathuthukisa kanjani ukusebenza kahle kwamandla kwezakhiwo, ikakhulukazi ebusika,” kusho uWang, ophinde asebenze e-Institute of Architecture and Materials ePennsylvania School of Art and Architecture.
Ithimba liqale lenza imodeli yokulinganisa ukuthi kungakanani ukushisa okuvela elangeni okungaboniswa, kudonswe, noma kudluliselwe ngamafasitela ambozwe ngama-nanoparticles ensimbi.Bakhethe inhlanganisela ye-photothermal ngenxa yekhono layo lokumunca ukukhanya kwelanga okune-infrared ngenkathi isahlinzeka ngokudluliswa kokukhanya okwanele okubonakalayo.Imodeli ibikezela ukuthi i-coating ikhombisa kancane eduze kokukhanya kwe-infrared noma ukushisa futhi idonsa kakhulu ngefasitela kunezinye izinhlobo eziningi zama-coatings.
Abacwaningi bahlole amafasitela engilazi enefasitelana elilodwa elimbozwe ngama-nanoparticles ngaphansi kokukhanya kwelanga okufanisiwe elebhu, okuqinisekisa ukubikezela kokulingisa.Izinga lokushisa ohlangothini olulodwa lwefasitela eline-nanoparticle likhuphuke kakhulu, liphakamisa ukuthi ukumboza kungamunca ukushisa okuvela ekukhanyeni kwelanga okuvela ngaphakathi ukuze kunxephezele ukulahlekelwa ukushisa kwangaphakathi ngamafasitela anefasitelana elilodwa.
Abacwaningi babe sebedlulisela idatha yabo ekulingiseni okukhulu ukuze bahlaziye ukonga amandla esakhiwo ngaphansi kwezimo zezulu ezihlukahlukene.Uma kuqhathaniswa namakhethini aphansi akhipha umoya wamafasitela angawodwa atholakala ngokwentengiso, ama-photothermal adonsa ukukhanya okuningi ku-spectrum eseduze ne-infrared, kuyilapho amafasitela anombala ovamile akubonisa ngaphandle.Lokhu kumuncwa kwe-infrared kuphumela ekulahlekeni kokushisa okungaphansi okungamaphesenti angu-12 ukuya kwangu-20 kunamanye ama-coatings, futhi amandla esakhiwo onge amandla afinyelela cishe kumaphesenti angu-20 uma kuqhathaniswa nezakhiwo ezingaboshiwe kumawindi anefasitelana elilodwa.
Kodwa-ke, u-Wang uthe ukuqhutshwa kwe-thermal okungcono, inzuzo ebusika, kuba yinkinga ngenkathi efudumele.Ukulandisa ngezinguquko zesizini, abacwaningi baphinde bahlanganisa ama-canopies kumamodeli abo wokwakha.Lo mklamo uvimbela ukukhanya kwelanga okuqondile okushisisa indawo ezungezile ehlobo, ikakhulukazi kuqede ukudluliswa kokushisa okungekuhle kanye nanoma yiziphi izindleko zokupholisa ezihlobene.Ithimba lisasebenza kwezinye izindlela, ezihlanganisa amasistimu amafasitela aguquguqukayo ukuze ahlangabezane nezidingo zokushisisa nezokupholisa zesizini.
"Njengoba lolu cwaningo lubonisa, kulesi sigaba socwaningo, sisengakwazi ukuthuthukisa ukusebenza okushisayo okuphelele kwamafasitela ane-glazed eyodwa ukuze kufane namafasitela aphindwe kabili ebusika," kusho u-Wang."Le miphumela inselele izixazululo zethu zendabuko zokusebenzisa izendlalelo eziningi noma ukufakwa kwe-insulation ukuze sibuyisele amafasitela ekamelo elilodwa ukonga amandla."
“Ngenxa yesidingo esikhulu sezakhiwo zokwakha ingqalasizinda yamandla kanye nemvelo, kubalulekile ukuthi sithuthukise ulwazi lwethu ukuze sakhe izakhiwo ezonga ugesi,” kusho u-Sez Atamtürktur Russcher, uSolwazi Harry no-Arlene Schell kanye neNhloko Yezobunjiniyela Bokwakha.“UDkt.UWang nethimba lakhe benza ucwaningo oluyisisekelo olusebenzayo.

Abanye ababambe iqhaza kulo msebenzi bahlanganisa u-Enhe Zhang, umfundi oneziqu ekwakhiweni kwezakhiwo;U-Qiuhua Duan, Umsizi Woprofesa Wobunjiniyela Bomphakathi eNyuvesi yase-Alabama, uthole i-PhD yakhe ku-Architectural Engineering e-Pennsylvania State University ngoDisemba 2021;U-Yuan Zhao, umcwaningi kwa-Advanced NanoTherapies Inc., obambe iqhaza kulo msebenzi njengomcwaningi we-PhD e-Pennsylvania State University, u-Yangxiao Feng, umfundi we-PhD ekwakhiweni kwezakhiwo.I-National Science Foundation kanye ne-USDA Natural Resources Conservation Service bawusekela lo msebenzi.
Izembozo zamawindi (ama-molecule asondelene) zibonisiwe ukuthi zithuthukisa ukudluliswa kokushisa okuvela elangeni langaphandle (imicibisholo ewolintshi) ukuya ngaphakathi kwesakhiwo kuyilapho zisahlinzeka ngokudluliswa kokukhanya okwanele (imicibisholo ephuzi).Umthombo: Isithombe sihlonishwa nguJulian Wang.Wonke Amalungelo Agodliwe.
