(a) Ac-IVD solution droplet evaporating on a superhydrophobic PMMA surface. The droplet was raster-scanned at specific times using a 1 µm SR beam (Hauser et al., 2011BB35). Nanofibrillation is observed at the droplet interface (grey square) via a 0.47 nm cross-β-type peak at t ≃ 40 min after droplet deposition. The white arrow indicates the orientation of the fibre axis. (b) Optical image of hollow residue attached to glass capillary. (c) Raster-diffraction image of hollow residue. (d) Zoom into the diffraction patterns from within the rectangular zone in (c). The radial orientation of the cross-β fibre axes is indicated by the arrows. (e) Selected cross-β diffraction pattern. The strongest peaks along the meridional (m) fibre axis (arrow) and equatorial (e) directions are indicated. (f) Intensity distribution along the fibre axis fitted by six Bragg and two short-range-order peaks. The peaks are indicated in (e). [Adapted from Hauser et al. (2011BB35).] The Bragg peaks can be indexed for a 5.72 nm cross-β period.
