Diffraction studies have been successful in determining the position of atoms in a unit cell, or determining the periodicity of a structure. However, most common materials in our daily life are not ordered. Still, their structures at different levels have direct implication on material properties. Scattering provides robust signature of the internal spatial arrangement of any system. However, contrary to the dilute particle scattering or crystal structure analysis, there is no way of ab initio transformation into real-space structure. We need one step of interpreting the signature according to the a priori knowledge of the system. I am going to discuss several examples of X-ray and light scattering of cellulose-related systems.
