Accurate characterization of atomic arrangement in materials is fundamental for understanding and predicting properties at the macro scale. Scattering and diffraction have proven to be powerful methods to inquiry about atomic arrangement and dynamic in ordered materials (crystals). Nonetheless, the atomic arrangement in nanomaterials deviates from the periodicity expressed by their bulk counterparts. Imperfections make challenging to apply any of state-of-the-art data analysis techniques to nanostructured materials. Structural disorder yields loss of signal in the experiments and increased complexity/- uncertainty of models. The solution of features across different scales, such as atom-pair interactions, structure defects, and long-range lattice distortion, requires overcoming limitations in available analysis methods. Our goal is to advance analysis of scattering data to support the systematic investigation of ‘disorder’ in nanostructured materials.
