Kuphunzira Kwambiri Kumagwiritsa Ntchito Femtosecond X-Ray Crystallography Kuti Awonetsere Mapangidwe Amphamvu a 3D a MOFs

Makina a crystalline okhala ndi timiyala tating'onoting'ono ta mamolekyu atuluka ngati zida zodalirika zogwiritsa ntchito mosiyanasiyana. Ndikofunikira kwambiri kuwonetsa osati mawonekedwe awo osasunthika komanso kutembenuka kwa mapangidwe awo poyankha zokopa zakunja. Femtosecond time-resolved crystallography imatha kufufuza zochitika zenizeni zenizeni za kusintha kwapangidwe, koma, mpaka pano, izi sizinakwaniritsidwe chifukwa cha kusintha kwa mankhwala mu makristasi omwe si achilengedwe.

Poganizira izi, Hyotcherl Ihee wa ku Korea Advanced Institute of Science and Technology ndi anzake adanenanso za kugwiritsa ntchito njira yowonetsera nthawi ya femtosecond crystallography (TR-SFX) kuti aphunzire za MOF. TR-SFX ndi njira yomwe imagwiritsidwa ntchito kwambiri pofotokozera mapangidwe a mapuloteni, ndipo olemba adayigwiritsa ntchito powonetsa ma MOF okhala ndi masamba a Fe-porphyrin ndi magulu azitsulo a hexazirconium.
