China / Japan: Abacwaningi Kyoto University, University of Tokyo Japan futhi Jiangsu Okuvamile University e China ziye zasungula izinto ezintsha ukuthi can ngokukhetha bamba carbon dioxide (CO 2) molecule ukuguqula wabayisa izinto 'ewusizo' organic, kuhlanganise kuyisandulela i-polyurethane. Le phrojekthi ucwaningo iye yachazwa ezinhlwini ezingu Umagazini i-Nature nokuxhumana.
Indaba kuyinto ukungena nakwamanye amazwe ukubambisana polymer (PCP, eyaziwa nangokuthi uhlaka lwensimbi organic), uhlaka ehlanganisa zinc metal ion. Abacwaningi ihlolwe kusetshenziswa-X-ray ukuhlaziywa zabo ezibonakalayo kwesakhiwo wathola ukuthi kungaba ngokukhetha uthwebule CO kuphela 2 molecule nge izikhathi eziyishumi uhambe kahle kunamanye PCPs. Indaba ine ingxenye organic nge bendiza-like ukwakheka kwama-molecule, futhi njengoba CO 2 molecule asondele isakhiwo, uphendukisa futhi uhlele ukuba ivumele CO 2 ukudoba, okuholela nezinguquko ezincane kuziteshi yamangqamuzana ngaphakathi PCP. Lokhu kuyivumela ukuba abe njengomholi ka ngesihlungo yamangqamuzana ingaze molecule nge isayizi shape. I PCP futhi kabusha; nekusebenta kulethe sisekhona ngisho nangemva 10 ukuphendula imijikelezo.
Ngemva lathumba carbon, indaba eguquliwe ingasetshenziswa ukwenza polyurethane, material nge ezihlukahlukene izicelo kuhlanganise ukwahlukanisa izinto.
