Uphononongo oluGroundbreaking luSebenzisa i-Femtosecond X-Ray Crystallography ukubonisa i-3D Dynamic Structure ye-MOFs

Iinkqubo zeCrystalline ezibandakanya iibhloko zokwakha zemolekyuli ezincinci ziye zavela njengezinto ezithembisayo ezinosetyenziso olwahlukeneyo. Kubaluleke kakhulu ukubonakalisa kungekuphela nje izakhiwo zabo ezimileyo kodwa kunye nokuguqulwa kwezakhiwo zabo ekuphenduleni i-stimuli yangaphandle. I-Femtosecond i-crystallography esonjululwe lixesha le-Femtosecond inamandla okuvavanya amandla exesha lokwenyani lotshintsho lwesakhiwo, kodwa, ukuza kuthi ga ngoku, oku akukaphunyezwa ngenxa yokusabela kweekhemikhali kwiikristale ezingezizo ezebhayoloji.

Ngenxa yoku, u-Hyotcherl Ihee waseKorea Advanced Institute of Science and Technology kunye noogxa bakhe babika ukusetyenziswa kwe-serial ye-serial femtosecond crystallography (TR-SFX) ye-serial egqityiweyo yokufunda i-MOF izakhiwo. I-TR-SFX yindlela eqhelekileyo esetyenziswayo yokubonakalisa ubume beprotein, kwaye ababhali bayisebenzise ukubonisa iimpawu ze-MOF eziqulethe iisayithi ze-Fe-porphyrin kunye ne-hexazirconium metal clusters.
