Kev tshawb fawb thiab thev naus laus zis niaj hnub Washington, Lub Xya Hli 23 (xinhua liu) Georgia lub koom haum ntawm cov kws tshawb fawb thev naus laus zis 23 nyob rau hauv American chemical Association journal ACS sustainable chemistry thiab engineering tau luam tawm tsab ntawv tshawb fawb, lawv siv cov ntaub ntawv muab rho tawm ntawm lub plhaub thiab cov ntoo los ua ib puag ncig tshiab. kev tiv thaiv zaj duab xis, tuaj yeem cais tawm cov pa oxygen zoo dua, xav tias yuav dhau los ua cov khoom noj khoom haus uas tau siv dav hauv kev txuag cov khoom noj.
Cov ntaub ntawv rho tawm los ntawm crab plhaub thiab ntoo yog chitin thiab cellulose, feem. Lawv hloov pauv chitin nanodimensional fiber ncua kev kawm ntawv thiab cellulose nanocrystal ncua kev kawm ntawv ntawm polylactate zaj duab xis raws li ib tug substrate, qhuav tam sim ntawd los tsim ib tug tshiab zaj duab xis muaj li ntawm chitin nanofiber txheej thiab cellulose nanocrystal txheej. Cov yeeb yaj kiab no tsis yog hloov pauv, pob tshab, tab sis kuj biodegradable thiab zoo ib puag ncig.
Ua tsaug rau cov qauv siv lead ua, cov yeeb yaj kiab tshiab tuaj yeem tiv thaiv kev nkag mus ntawm cov pa oxygen molecules thiab dhau los ua cov khoom thaiv nrog huab cua nruj.
