摘要：
It's under control: In the presence of an artificial double-hydrophilic block copolymer, poly(ethylene glycol)-b-poly(L-glutamic acid), highly monodisperse vaterite microspheres crystallize from a mixture of N,N-dimethylformamide and water (see picture). Varying the ratio of the solvents can control the morphology of the CaCO3 crystals. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
