摘要：

Partially filling a colloidal crystal can give rise to mesoscopic rings (see scheme). The liquid forms rings by capillary forces in the wedges around the contact points between particles. The liquid is solidified, the templating particles are removed, and dispersions of solid rings remain. (Chemical Equation Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
