Structural Hierarchy (particulate) Adapted from DW Schaefer MRS Symposium Proceeding 1987 Structural information viewed on five length scales. Structural features at larger length scales are observed at smaller Q. Scattering analysis that describes hierarchical structures: Mass Fractal (Teixeira), Unified Fit (Beaucage) combine power law scattering ranges with Rg transitions 63 Managed by UT-Battelle for the U.S. Department of Energy Presentation_name
