Key Takeaways
- Kev loj hlob ntawm cov khoom kho tus kheej tuaj yeem muaj ib hnub txhais tau tias cov khoom siv uas tsis xav tau kho.
- Cov kws tshawb fawb tau tsim kho tus kheej nanocrystals uas tuaj yeem siv rau hauv cov khoom siv hluav taws xob.
- Cov kws tshawb fawb Australian tsis ntev los no tau qhia ib txoj hauv kev los pab 3D-luam yas kho nws tus kheej ntawm chav tsev kub siv lub teeb xwb.
Tsis nco qab hloov qhov tawg vim tias koj lub xov tooj smartphone ib hnub yuav tuaj yeem kho nws tus kheej.
Cov kws tshawb fawb hais tias lawv tau tshawb pom tus kheej kho nanocrystals uas tuaj yeem siv rau hauv cov khoom siv hluav taws xob. Cov nanocrystals yog tsom rau cov hnub ci vaj huam sib luag tab sis tuaj yeem muaj ntau yam kev siv hauv hluav taws xob. Nws yog ib feem ntawm kev siv zog los nrhiav cov khoom siv kho lawv tus kheej kom txo cov khib nyiab.
"Cov neeg siv tam sim no yuav tuaj yeem kho cov kab nrib pleb ntawm cov khoom siv tsis tau dhau los ntawm tes," tus kws tshaj lij Jonathan Tian hais rau Lifewire hauv kev xam phaj email. "Feem ntau, thaum lub sijhawm so, tag nrho cov nti (lossis tag nrho cov cuab yeej) tuaj yeem muab pov tseg. Tsis tas li ntawd, los ntawm kev txuas lub neej ntawm cov tshuab hluav taws xob, kev kho tus kheej yuav txo qis cov khoom siv hluav taws xob nkag mus rau ib puag ncig."
Hlub koj tus kheej
Thaum cov ntaub ntawv kho tus kheej yuav zoo li kev tshawb fawb tsis tseeb los ntawm cov yeeb yaj kiab zoo li Terminator lossis Spiderman, lawv tau dhau los ua qhov tseeb. Cov kws tshawb fawb Israel lub koom haum thev naus laus zis tsis ntev los no tau tsim eco-friendly nanocrystal semiconductors muaj peev xwm kho tus kheej.
Cov txheej txheem siv ib pawg ntawm cov ntaub ntawv hu ua ob chav perovskites uas qhia txog kev kho tus kheej tom qab raug puas tsuaj los ntawm hluav taws xob hluav taws xob. Lub perovskites, thawj zaug pom nyob rau hauv 1839, tsis ntev los no tau txais cov kws tshawb fawb 'kev saib xyuas vim muaj cov yam ntxwv ntawm cov khoom siv kho qhov muag uas ua rau lawv muaj txiaj ntsig zoo hauv kev hloov hluav taws xob, txawm tias pheej yig ntau lawm. Cov perovskites tuaj yeem pab tau hauv cov hnub ci hnub ci.
Cov perovskite nanoparticles tau tsim nyob rau hauv lub lab siv luv luv, yooj yim txheej txheem uas koom nrog cua sov cov khoom rau ob peb feeb. Ib lub tshuab hluav taws xob xa hluav taws xob ua rau muaj qhov yuam kev thiab qhov hauv nanocrystals.
Cov neeg tshawb xyuas "pom tias lub qhov tau txav mus los hauv nanocrystal tab sis zam nws cov npoo," pab pawg tau sau hauv xov xwm tshaj tawm. "Cov kws tshawb fawb tau tsim ib txoj cai uas tshuaj xyuas kaum ob ntawm cov yeeb yaj kiab uas siv lub tshuab ntsuas hluav taws xob kom nkag siab txog kev txav mus los hauv cov siv lead ua. Lawv pom tias qhov tau tsim nyob rau saum npoo ntawm cov nanoparticles, thiab tom qab ntawd tsiv mus rau qhov chaw ruaj khov nyob hauv."
Kev Loj Hlob
Kev kho tus kheej cov ntaub ntawv tau nthuav dav sai. Piv txwv li, Australian cov kws tshawb fawb tsis ntev los no tau qhia ib txoj hauv kev los pab 3D-luam luam yas kho nws tus kheej ntawm chav tsev kub uas siv lub teeb xwb. Pab pawg University of New South Wales tau qhia tias ntxiv "cov hmoov tshwj xeeb" rau cov kua dej siv hauv cov txheej txheem luam ntawv tom qab tuaj yeem pab kho sai thiab yooj yim yog tias cov khoom tawg.
Lub teeb txheem LED teeb tuaj yeem kho cov ntawv luam tawm hauv ib teev, uas ua rau muaj tshuaj lom neeg thiab fusion ntawm ob daim tawg.
Cov kws tshawb fawb tau hais tias tag nrho cov txheej txheem ua rau cov yas kho dua tshiab dua ua ntej nws puas lawm. Cia siab tias kev txhim kho ntxiv ntawm cov txheej txheem yuav pab txo cov tshuaj pov tseg yav tom ntej.
"Nyob hauv ntau qhov chaw uas koj siv cov khoom siv polymer, koj tuaj yeem siv cov thev naus laus zis no," Nathaniel Corrigan, ib tus ntawm pab pawg tau hais hauv xov xwm tshaj tawm. "Yog li, yog tias cov khoom ua tsis tiav, koj tuaj yeem kho cov khoom yam tsis tas yuav muab pov tseg. Nws muaj qhov txiaj ntsig zoo ib puag ncig vim tias koj tsis tas yuav rov ua cov khoom lag luam tshiab txhua zaus nws tawg. lub neej ntawm cov ntaub ntawv no, uas yuav txo tau cov pov tseg yas."
Bram Vanderborght, tus xibfwb ntawm Vrije Universiteit Brussel hauv Belgium, yog ib feem ntawm pab pawg ua haujlwm kho tus kheej kho neeg hlau grippers. Cov grippers siv cov polymers kho tus kheej thiab yog siv rau hauv ib puag ncig uas cov neeg hlau feem ntau puas. "Tab sis cov thev naus laus zis no thiab peb txoj haujlwm tseem muaj cov ntawv thov dhau ntawm daim ntawv thov tam sim no," Nws hais rau Lifewire hauv kev xam phaj email.
Kev kho tus kheej neeg hlau tuaj yeem muab kev ywj pheej ntxiv rau yav tom ntej.
"Peb tuaj yeem cia siab tias yuav muaj kev vam meej hauv kev tsim cov khoom siv kev puas tsuaj uas txhawb nqa hluav taws xob thiab neeg hlau ua haujlwm," Tian hais. "Cov kab ke no yuav suav nrog cov ntaub ntawv muaj peev xwm txheeb xyuas qhov kev puas tsuaj, qhia txog qhov xwm txheej, thiab kho lossis kho cov khoom siv los txo qhov kev puas tsuaj kom tsis txhob ua tsis tiav lossis kev puas tsuaj yav tom ntej."
