Lub neej puv nkaus ntawm cov ntim khoom ci ntsa iab, cov fwj tshuaj pleev ib ce, cov tais txiv hmab txiv ntoo thiab ntau ntxiv, tab sis ntau ntawm lawv yog ua los ntawm cov khoom lom thiab tsis ruaj khov uas ua rau muaj kuab paug yas.
Tsis ntev los no, cov kws tshawb fawb ntawm University of Cambridge hauv UK tau pom ib txoj hauv kev los tsim cov khoom ci ntsa iab uas ruaj khov, tsis muaj tshuaj lom thiab lwj tau los ntawm cellulose, lub hauv paus tseem ceeb ntawm phab ntsa cell ntawm cov nroj tsuag, txiv hmab txiv ntoo thiab zaub. Cov ntawv cuam tshuam tau luam tawm hauv phau ntawv xov xwm Nature Materials rau hnub tim 11.
Ua los ntawm cov cellulose nanocrystals, cov khoom ci ntsa iab no siv cov xim ntawm lub cev los hloov lub teeb kom tsim cov xim ci ntsa iab. Piv txwv li, hauv xwm, cov tis ntawm npauj npaim thiab cov plaub noog peacock yog cov xim zoo nkauj, uas yuav tsis ploj mus tom qab ib puas xyoo.
Cov kws tshawb fawb hais tias siv cov txheej txheem sib dhos ua ke, cellulose tuaj yeem tsim cov yeeb yaj kiab xim ci ntsa iab. Los ntawm kev ua kom zoo dua cov tshuaj cellulose thiab cov txheej txheem txheej, pab pawg tshawb fawb tau tswj hwm tag nrho cov txheej txheem sib dhos ua ke, tso cai rau cov khoom siv los tsim ntau hauv cov yob. Lawv cov txheej txheem sib xws nrog cov tshuab lag luam uas twb muaj lawm. Siv cov ntaub ntawv cellulosic muaj nyob hauv khw, nws tsuas yog siv ob peb kauj ruam los hloov mus rau hauv cov tshuaj uas muaj cov glitter no.
Tom qab tsim cov cellulose zaj duab xis loj heev, cov kws tshawb fawb tau zom lawv ua tej daim me me uas siv los ua cov xim ci ntsa iab lossis cov xim pleev xim. Cov pellets no lwj tau, tsis muaj yas, thiab tsis muaj tshuaj lom. Ntxiv mus, cov txheej txheem no siv zog tsawg dua li cov txheej txheem ib txwm muaj.
Lawv cov khoom siv tuaj yeem siv los hloov cov yas glitter me me thiab cov xim me me uas siv dav hauv cov tshuaj pleev ib ce. Cov xim ib txwm muaj, xws li cov hmoov glitter siv rau hauv kev siv txhua hnub, yog cov khoom siv tsis ruaj khov thiab ua rau cov av thiab dej hiav txwv qias neeg. Feem ntau, cov xim minerals yuav tsum tau cua sov ntawm qhov kub siab ntawm 800 ° C los tsim cov xim me me, uas kuj tsis zoo rau ib puag ncig ntuj.
Cov zaj duab xis cellulose nanocrystal uas pab neeg npaj tau tuaj yeem tsim tau ntau yam los ntawm kev siv cov txheej txheem "roll-to-roll", ib yam li ntawv ua los ntawm ntoo pulp, ua rau cov khoom no siv rau kev lag luam thawj zaug.
Nyob teb chaws Europe, kev lag luam tshuaj pleev ib ce siv li ntawm 5,500 tons ntawm cov yas me me txhua xyoo. Tus sau ntawv laus ntawm daim ntawv, Xibfwb Silvia Vignolini, los ntawm Yusuf Hamid Department of Chemistry ntawm University of Cambridge, tau hais tias lawv ntseeg tias cov khoom no tuaj yeem hloov pauv kev lag luam tshuaj pleev ib ce.
