Shiinaha / Japan: Cilmi oo ka tirsan jaamacadda Kyoto, University of Tokyo ee dalka Japan iyo University Jiangsu Normal ee Shiinaha ayaa soo saartay qalab cusub oo awoodo eegista qabashada carbon dioxide (CO 2) taagoo oo iyaga loogu badalo galay qalabka organic 'waxtar leh', oo ay ku jiraan maamaan ah waayo, polyurethane. Mashruuc cilmi baaris ayaa lagu qeexay in Macalester Nature Isgaarsiinta.
Maaddadu ay tahay polymer ah isuduwidda furan (PCP, sidoo kale loo yaqaan qaab bir-organic a), qaab-dhismeed ka kooban udhigo biraha zinc. Cilmibaadhayaasha ayaa baaro oo ay wax la isticmaalayo X-ray falanqaynta dhismaha oo wuxuu helay in eegista qabsan karaa oo keliya CO 2 molecules leh min toban hufnaan badan PCPs kale. Qoraalkani wuxuu ku leeyahay qayb organic la rafaasad u eg qaab kelli, iyo sida CO 2 molecules u dhowaan qaab-dhismeedka, ay isku shaandheyn iyo qabanqaabin doonaa in la oggalaado CO 2 qoynin, taasoo keentay in isbedel yar u channels kelli gudahood PCP ah. Tani waxay u ogolaaneysaa in ay u dhaqmaan sida shaandho kelli in la aqoonsado kartaa taagoo by size iyo qaabka. Sidoo kale PCP waa loo cusboneysiin karo, oolnimada of Hannaan ma hoos u xitaa ka dib markii 10 wareegyada falcelin.
Ka dib markii qabsaday carbon ah, waxyaabaha la gediyay waxaa loo isticmaali karaa si ay u sameeyaan polyurethane, qalab kala duwan balaadhan oo ah codsiyada oo ay ku jiraan qalabka madhxiya.
