Content

Structures and assemblies on the nanometer scale generally pose considerable challenges on experimental techniques. In contrast to techniques such as electron microscopy and atomic force microscopy that are well suited for surfaces and thin sections, non-destructive “see through” methods such as x-ray and neutron methods can be used to make the interior of bulk samples visible and are particularly suitable for biological materials. Their non-destructive nature allows the combination of different methods and time-resolved monitoring of structural and chemical changes.

- Introduction: Use of x-ray and neutron methods for nanostructure characterization
- Generation of x-rays, Interaction of x-rays with matter
- Crystal structure determination with x-ray diffraction
- Small-angle x-ray scattering for macromolecular assemblies, nanocomposites etc.
- Chemical analysis with x-rays: fluorescence, x-ray absorption spectroscopy
- Watching processes: time-resolved in-situ methods
- Large facilities, advanced techniques (Synchrotron radiation,
Microfocus/nanofocus techniques)
- Neutrons: generation of neutrons, interaction with matter
- Neutron scattering vs. x-ray scattering
Previous knowledge expected

Physics and mathematics knowledge at university intoductory course level
Objective (expected results of study and acquired competences)

Students graduating from this course have a basic understanding of x-ray and neutron methods in materials science with specific emphasis on nanostructured materials. They are able to use this knowledge to solve basic problems in nanostructure characterization and posess an overview of state-of-the-art methods and trends.
