SAXS measurements were conducted on the SAXSpoint 5.0 (Anton Paar, Graz, Austria) coupled to a MetalJet D2 X-ray source (Excillum, Kista, Sweden). An X-ray beam with a wavelength (𝜆) of 0.134 nm (9.3keV) and sample-to-detector distance of 1608.1 mm, provides a q-range from 0.04 -2.4 nm -1 . The scattering vector magnitude q was calculated with Eq. 1,
