Abstract

Nanomaterials exhibit unique properties which has made them a hot topic in research lately. X-ray scattering has proven to be a valuable characterization technique for nanomaterials, as it gives average properties over a large sample volume, in contrast to electron microscopy. Techniques like Small Angle X-ray Scattering (SAXS), Pair Distribution Function (PDF) analysis and Grazing Incidence Small Angle X-ray Scattering (GI-SAXS) are extensively used at synchrotron beamlines and sometimes also on dedicated laboratory instruments. What is less known, is that also modern multi-purpose powder diffractometers can cover these applications. In this seminar, I will show examples of the data quality that is nowadays possible with these instruments.
