diameters from ~300 nm down to 0.2 nm. In this regard, scattering for q<~5 nm -1 would be typically classified as SAXS, and q>~5 nm -1 as WAXS, where SAXS originates from the intermolecular features in the material (e.g. particles, pores, interfaces etc.), whereas WAXS represents the intramolecular length-scale features (supramolecular-and atomic-level structures). There is of course also a conceptual cross-over qrange between SAXS and WAXS which depends on the material. In our lignin samples the recorded scattering patterns exhibited the following characteristic intensity regions:
