Image reconstruction of the macroporous silica particle at different RHs. (a) Upsampled diffraction patterns of the silica particle. The pattern was upsampled by 4 × 4, and then the Friedel average was applied. The central black-crossed areas were masked because of parasitic scatterings. (b) Projected electron density maps reconstructed from the patterns in (a). The opening of the pores at the periphery of the map are indicated by arrowheads. One pixel corresponds to 37.4 nm. (c) Phase retrieval transfer function of the maps at 5.2% RH (solid line) and 82.6% RH (broken line). The thin lines indicate the spatial frequencies corresponding to the effective resolution. The scale bars in (b) indicate 1 µm. The colour scales are shown at the top (a) and left (b) of each panel.
