説明

<jats:p><jats:bold>New insights into the mechanism of crystal nucleation</jats:bold> emerge from a study by <jats:italic>Kondepudi</jats:italic> et al., on the crystallization of NaClO<jats:sub>3</jats:sub> from a stirred solution. Rectangular prisms of the chiral space group <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>3 precipitate from aqueous solutions of the <jats:italic>achiral</jats:italic> 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 NaClO<jats:sub>3</jats:sub> 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.</jats:p>
