From: In situ observation of coalescence of nuclei in colloidal crystal-crystal transitions

Fig. 5

a At t = 1260 s, notice a rectangular nucleus on a GB and a triangular nucleus at a triple junction. b At t = 1325 s, both nuclei grow. c The nucleus on the GB grows towards the triple junction and becomes triangular in shape. d Two nuclei merge together. e The nucleus becomes rectangular after coalescence. The colours in (a–d) represent the dynamic Lindemann parameter for each particle. Scale bar: 5 μm. f, The evolution of the separation between two nuclei.
