Chair: Thomas Proffen. Structure determination is usually based on the analysis of Bragg reflections yielding the average structure of the material. However, many materials are quite disordered or show limited long range as in the case of nanomaterials. By analyzing the total scattering pattern structural one can obtain structural information as a function of length scale from the local structure to the medium and finally long range structure. The Pair Distribution Function (PDF) technique is a more and more popular way to obtain a picture of the 'true' structure. PDFs can now be obtained covering atom-atom distances in excess of 15nm overlapping with the lower end of the accessible length scale by Small Angle Scattering (SAS). This session will explore the two techniques and how they can be applied in combination to obtain a more complete structural picture of complex systems ranging from biology to material science. |
