UNIVERSITY PARK, Pennsylvania - Lifensetere tse khabisitsoeng habeli tse kentsoeng ka moea o sireletsang moea li ka fana ka matla a matla ho feta lifensetere tse nang le phanele e le 'ngoe, empa ho nkela lifensetere tse teng tse nang le phanele e le 'ngoe ho ka bitsa chelete e ngata kapa phephetso ea botekgeniki.Khetho e eketsehileng ea moruo, empa e sa sebetseng haholo ke ho koahela lifensetere tsa kamore e le 'ngoe ka filimi ea tšepe e khanyang, e monyang mocheso o mong oa letsatsi mariha ntle le ho senya ponahalo ea khalase.Ho ntlafatsa ts'ebetso ea ho roala, bafuputsi ba Pennsylvania ba re nanotechnology e ka thusa ho tlisa ts'ebetso ea mocheso ho ea boemong bo lekanang le lifensetere tse benyang habeli mariha.
Sehlopha se tsoang Lefapheng la Pennsylvania la Architectural Engineering se ile sa batlisisa mekhoa ea ho boloka matla ea liphahlo tse nang le likaroloana tsa nanoscale tse fokotsang tahlehelo ea mocheso le ho monya mocheso hamolemo.Ba boetse ba phethela tlhahlobo ea pele e felletseng ea matla a matla a thepa ea moaho.Bafuputsi ba phatlalalitse seo ba se fumaneng ho Energy Conversion and Management.
Ho ea ka Julian Wang, motlatsi oa moprofesa oa boenjiniere ba meralo, leseli le haufi le infrared - karolo ea khanya ea letsatsi eo batho ba ke keng ba e bona empa ba khona ho utloa mocheso - e ka etsa hore ho be le phello e ikhethang ea photothermal ea li-nanoparticles tse itseng tsa tšepe, ho eketsa ho phalla ha mocheso ka hare.ka fensetere.
"Re thahasella ho utloisisa hore na liphello tsena li ka ntlafatsa matla a matla a mehaho joang, haholo-holo mariha," ho boletse Wang, eo hape a sebetsang Setsing sa Mehaho le Lisebelisoa Sekolong sa Pennsylvania sa Art and Architecture.
Sehlopha sa pele se ile sa qapa mohlala oa ho hakanya hore na mocheso o mokae o tsoang khanyeng ea letsatsi o tla bonahatsoa, ​​o monye kapa o fetisoe lifensetereng tse koahetsoeng ka tšepe ea nanoparticles.Ba ile ba khetha motsoako oa photothermal ka lebaka la bokhoni ba oona ba ho monya khanya ea letsatsi e haufi le infrared ha e ntse e fana ka phetiso e lekaneng ea khanya e bonahalang.Moetso o bolela esale pele hore koae e bonahatsa leseli le tlase haufi le infrared kapa mocheso mme e monya haholo ka fensetere ho feta mefuta e meng e mengata ea liphahlo.
Bafuputsi ba ile ba leka lifensetere tsa khalase e nang le phanele e le 'ngoe e koahetsoeng ka li-nanoparticles tlas'a khanya ea letsatsi ka laboratoring, ho tiisa likhakanyo tsa papiso.Thempereichara ka lehlakoreng le leng la fensetere e koahetsoeng ka nanoparticle e ile ea eketseha haholo, e fana ka maikutlo a hore seaparo se ka monya mocheso o tsoang letsatsing ho tloha ka hare ho lefella tahlehelo ea mocheso oa ka hare ka lifensetere tse nang le phanele e le 'ngoe.
Ka mor'a moo, bafuputsi ba ile ba fepa lintlha tsa bona ka lipapiso tse kholo ho hlahloba poloko ea matla ea mohaho tlas'a maemo a sa tšoaneng a leholimo.Ha ho bapisoa le likhase tse fokolang tsa lifensetere tse fumanehang khoebong, liphaephe tsa photothermal li monya boholo ba khanya e haufi le mabone a infrared, ha lifensetere tse koahetsoeng ka tloaelo li le bontša ka ntle.Mocheso ona o haufi le infrared o fella ka tahlehelo e tlase ea mocheso ka liperesente tse 12 ho isa ho tse 20 ho feta lirafshoa tse ling, 'me monyetla oa ho boloka matla oa moaho o fihla ho liperesente tse ka bang 20 ha ho bapisoa le meaho e sa koaheloang lifensetereng tse nang le phase e le 'ngoe.
Leha ho le joalo, Wang o boletse hore conductivity e ntle ea mocheso, e leng molemo nakong ea mariha, e fetoha bothata nakong ea mofuthu.Ho ikarabella bakeng sa liphetoho tsa nako ea selemo, bafuputsi le bona ba kentse li-canopies mefuteng ea bona ea meaho.Moralo ona o thibela khanya ea letsatsi e chesang haholoanyane hlabula, haholo-holo e felisa ho fetisa mocheso o fokolang le litšenyehelo tse amanang le ho pholisa.Sehlopha se ntse se sebetsa ka mekhoa e meng, ho kenyelletsa le litsamaiso tse matla tsa lifensetere ho fihlela litlhoko tsa ho futhumatsa le ho pholisa ka linako tsa selemo.
"Joalokaha phuputso ena e bontša, sethaleng sena sa thuto, re ntse re ka ntlafatsa ts'ebetso ea kakaretso ea mocheso oa lifensetere tse nang le likhalase tse le 'ngoe hore li tšoane le lifensetere tse peli tse khabisitsoeng ka nako ea mariha," ho boletse Wang."Liphetho tsena li phephetsa litharollo tsa rona tsa setso tsa ho sebelisa likhalase tse ngata kapa ho kenya letsoho ho nchafatsa lifensetere tsa kamore e le 'ngoe ho boloka matla."
"Ka lebaka la tlhokahalo e kholo ea thepa ea kaho ea meralo ea motlakase hammoho le tikoloho, ho bohlokoa hore re ntšetse pele tsebo ea rona ho theha meaho e baballang matla," ho boletse Sez Atamtürktur Russcher, Moprofesara Harry le Arlene Schell le Hlooho ea Boenjiniere ba Kaho.“Dr.Wang le sehlopha sa hae ba etsa lipatlisiso tsa mantlha tse ka sebelisoang. ”
Ba bang ba kenyang letsoho mosebetsing ona ba kenyelletsa Enhe Zhang, seithuti se fumaneng mangolo ka moralo oa meralo ea meralo;Qiuhua Duan, Motlatsi oa Moprofesa oa Boenjiniere ba Sechaba Univesithing ea Alabama, o ile a fumana PhD ea Architectural Engineering ho tloha Pennsylvania State University ka December 2021;Yuan Zhao, mofuputsi oa Advanced NanoTherapies Inc., ea kentseng letsoho mosebetsing ona e le mofuputsi oa PhD Univesithing ea Pennsylvania State, Yangxiao Feng, seithuti sa PhD sa moralo oa meralo.National Science Foundation le USDA Natural Resources Conservation Service li tšehetse mosebetsi ona.
Likoahelo tsa lifensetere (limolek'hule tse haufi-ufi) li bontšitsoe ho matlafatsa phetisetso ea mocheso ho tloha letsatsing la ka ntle (metsu ea lamunu) ho ea ka hare ho mohaho ha e ntse e fana ka phetiso ea khanya e lekaneng (metsu e mosehla).Mohloli: Setšoantšo se amoheloa ke Julian Wang.Litokelo tsohle li sirelelitsoe.
