Session Abstract

Three important classes of disordered materials are liquids, glasses and nanomaterials. Liquids have no long range order, but display localcorrelations and order between molecules. Similarly glasses are not crystalline materials, i.e. they are solids without long range order, but still with local order between atoms. Nanomaterials have short range order on the nanoscale. The short range sensitivity of XAS makes it ideal to study such materials and in total scattering analysis the weak diffuse features are related to the short and medium range order. This MS aims at highlighting strengths and limitations as well as the complementarity of spectroscopic and scattering techniques to understand the structural correlations on the atomic and molecular scale underpinning the macroscopic properties of disordered and nanostructured materials.
