摘要：

Prenucleation clusters: In situ synchrotron X-ray scattering with a one-second time resolution revealed the occurrence of nano-sized clusters during the nucleation and early growth of nanocrystals of a zeolitic imidazolate framework (ZIF). The complex crystallization process exhibits similarities with crystallization processes of zeolites from solution. Hmim= 2-methylimidazole. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
