Particulate samples were concentrated to 10 mg/ml and loaded into polycarbonate capillaries, sealed with parafilm. SAXS data was obtained for each composition using beamline I22 at Diamond Light Source (Oxford, UK). Diffraction patterns were collected using an X-ray energy of 12 keV (wavelength 1 Å) and a sample -detector distance of 3695.4381 mm. The raw data was treated using the protocol developed by beamline technicians at Diamond. Lattice parameters were calculated from generated Bragg peaks and phase assignments were made using the method described in the Results and discussion section.
