Figure 11.

Images of SsAPFs averaged without and with radial symmetry. The top rows of circular SsAPFs images were generated by averaging multiple images of the same size but without radial averaging; the number of images that were averaged is indicated in the upper right corner. The second row of images were radially averaged. Dashed circles represent approximated edges of the SsAPFs walls; the gap distance between the two circles is 3.0 nm. The proposed numbers of monomers, of radial unit-cells, and of monomers/unit-cell are indicated below the images.
