Figure 9 shows the SAXS analysis of the maghemite nanoparticles inside the bio-
foam matrix. The Figure detail shows the Gaussian deconvolution of the SAXS data.
This Gaussian deconvolution allowed several calculations, of which main results are
shown in Table 4. These SAXS results showed two main kinds of scattering centers.
These centers are related to superstructures, which present diameters equal to 60 and
38 nm, spaced from each other by 23 and 15 nm, respectively.
