Kondepudi等人对氯化钠在搅拌溶液中结晶的研究，为晶体成核机理提供了新的见解。手性空间群P2(1)3的矩形棱镜从非手性离子的水溶液中析出。如果不搅拌溶液，两种对构型晶体的析出量相等，这与近百年前的报道完全一致。然而，当NaClO3溶液被搅拌时，几乎只形成右旋或左旋晶体。对于这种极其令人惊讶且明显可重复的现象，有一个简单的解释。
New insights into the mechanism of crystal nucleation emerge from a study by Kondepudi et al., on the crystallization of NaClO3 from a stirred solution. Rectangular prisms of the chiral space group P2(1)3 precipitate from aqueous solutions of the achiral ions. If the solution is not stirred, crystals of both enantiomorphic forms precipitate in equal amounts exactly as was reported almost one hundred years ago. However, when the NaClO3 solution is stirred, then almost exclusively only right-handed or only left-handed crystals are formed. There is a simple explanation for this extremely surprising and obviously reproducible phenomenon.
