Cov kws ua haujlwm ntawm University of Cambridge hauv tebchaws Askiv tau tsim ib txoj hauv kev tshiab uas tuaj yeem siv lasers tshem tawm cov lus thiab cov duab luam tawm thiab luam tawm ntawm daim ntawv, uas yuav tsum nqa lub tshuab luam ntawv lossis tshuab luam ntawv nrog lub luag haujlwm "luag luam tawm" kom rov siv cov ntawv luam tawm. .
Cov thev naus laus zis tshem tawm cov toner number case uas twb tau luam tawm ntawm daim ntawv los ntawm cua sov nws nrog lub laser luv-mem tes. Lub laser vaporizes tus number case tsis ua rau daim ntawv puas, tshem tawm cov cwj mem stains ntawm ntau yam luam tawm thiab luam tawm hauv plaub billions ntawm ib thib ob. Cov kws tshawb fawb tseem pom tias thaum ob qho tib si ultraviolet thiab infrared lasers tau zoo ntawm kev tshem tawm cov number case, qhov zoo tshaj plaws yog pom ntsuab laser. Txoj kev no tsis ua rau muaj kev puas tsuaj rau daim ntawv, thiab nws tsis ua rau daim ntawv tsis muaj xim, thiab tus number case uas evaporates rau hauv roj tuaj yeem sau los ntawm lub lim.
"Cov txheej txheem ua haujlwm ntawm ntau hom toners yam tsis muaj kev puas tsuaj rau cov ntawv hauv qab lub tshuab luam ntawv, yog li nws yooj yim rau rov siv cov ntawv tam sim hauv chaw ua haujlwm." Lub tuam txhab ntseeg hais tias los ntawm ib puag ncig kev xav, thev naus laus zis yuav tsis tsuas yog txo qis cov ntoo rau daim ntawv, tab sis kuj tseem ua haujlwm raws li kev siv thev naus laus zis pheej yig dua. Ntau lub tuam txhab twb txaus siab rau qhov no thawj "luag lub tshuab luam ntawv."
Lub tuam txhab ntseeg tias "kev luam ntawv huv" thev naus laus zis yog ib puag ncig zoo dua li cov ntaub ntawv rov ua dua tshiab, tsis yog tsuas yog txo cov kev xav tau ntawm cov tshuaj, tab sis kuj txo qis carbon dioxide emissions los ntawm 79 feem pua.
Nws ntseeg tau tias kev tsim cov thev naus laus zis no sai sai yuav siv rau ntau yam kev lag luam, tshwj xeeb tshaj yog kev lag luam luam ntawv. Yuav coj peb ntau lub tshuab ua tsis tau tiav ua ntej!
