Collective lattice transformation within a single domain of icosahedron. (A–F) A series of TEM images show the transformation within a single tetrahedral subunit of an icosahedron along the two-fold axis (image size 870 × 598 pixels). (G) The averaged intensity profile along the box from x to y in (A) is plotted for each image at different times. Number 1–6 are used to label the first six disappearing lattice fringes.
