Figure 2
TEM images and diffraction patterns. (a) TEM of untreated fibrils and (b) sonicated fibrils, as well as (c) an enlargement from the sonicated sample showing the lateral striations and exposed ends of the individual filaments in the ribbon. The scale bars in (a)–(c) are all 0.2 µm. (d) Corresponding fibre diffraction patterns from dried samples of untreated fibril sample (left half) and sonicated fibrils (lower right quadrant). The simulated diffraction pattern based on the determined unit cell and the suggested packing model is included (upper right quadrant). (e) The diffraction pattern from a bundle of partly aligned needle-shaped crystals. Radial averages of the experimental diffraction images and the simulated pattern in the meridional (f) and equatorial (g) sections. For the meridional direction, only a selected range is depicted as the patterns are essentially featureless until 0.5 nm. |
