3D reconstruction of PS@Fe(acac)3 composite nanofibers and the spatial distribution of Fe(acac)3. (a) 3D reconstruction of PS@Fe(acac)3 composite nanofibers. The colorbar to the right indicates the sample density. The larger the value, the higher the density value, and it is proportional to the optical density. Color scale is in g cm−3. (b) Spatial distributions of Fe(acac)3 after dual-energy FS reconstruction from the same angle observation of (a). (c) Volume rendering of the nanofibers and distributions of Fe(acac)3 simultaneously. The `Temperature' colormap represents the fibers reconstructed from E = 705 eV [legend (1)] and the `VolrenGreen' colormap shows the Fe(acac)3 mapping [legend (2)]. Panel (c) is in the same rotation view as (a) and (b). Gray and yellow boxes are two obvious examples showing Fe(acac)3 inside the fibers. Scale bar: 1 µm. |
