Topic: “Small-angle scattering analyses of nanoporous materials

Abstract:

Countless technologies and chemical processes make use of nanoporous materials: heterogeneous catalysis, adsorption separation processes, and energy storage technologies provide numerous examples. Nanopores are also relevant to hosts of natural processes as diverse as the weathering of rocks, and ion transport through biological membranes. Many of these systems can be analyzed ex-situ using microscopy. However, when it comes to nanometre-scale analyses of materials in their natural working conditions, or of physicochemical processes taking place in the pores, small-angle scattering of x-rays (SAXS) or of neutrons (SANS) is often the only option. The lecture will start with a general presentation of small-angle scattering. The potential of the method will then be illustrated with various examples of ex- and in-situ studies using both ordered and disordered nanoporous materials. A particular focus will be put on data analysis procedures, whereby reciprocal-space data is converted to real-space structural information. The last part of the lecture will touch on the topic of inelastic scattering based on neutron spin-echo (NSE) experiments. These experiments supplement the structural information from SAXS or SANS with dynamical insights. The entire lecture will be kept non-technical and should be accessible to a broad audience.

The CRC cordially invites all who are interested to the lecture.
