detector as a single continuous signal. The sample-to-detector distance of ~330 mm allowed for a usable q-range of ~0.1 < q < 39 nm -1 . Transmission through the sample was calculated using an X-ray fluorescence signal collected from a lead beamstop using a RAYSPEC Sirius SD-E65133-BE-INC detector equipped with an 8 µm beryllium window, where the incoming beam intensity was monitored and normalised using an ion chamber. The scattering q-range was calibrated against silicon (NIST SRM640) and the corresponding measured intensity was calibrated to absolute units against water (at 20℃) and a glassy carbon standard (NIST SRM3600, 1 mm). The resulting data were processed with custom Python scripts utilizing a pyfai library . The processing steps included integration to 1D scattering curves and subtraction of an instrumental background (i.e. an "empty beamline" or "air" background).
