Small-angle scattering: Principles, data analysis and advanced modeling

18 Aug 2024, 18:00 → 23 Aug 2024, 23:59 Europe/Copenhagen

TBA (Niels Bohr Building)

Course description

This course will introduce you to the methods of small-angle scattering using x-rays and neutrons. The course will have a strong hands-on approach using a mixture of lectures, simulations, walked-through analysis examples and actual experimental measurements using KU’s 3 different SAXS machines. The course is evaluated through active participation and hand-ins during the course and a final report. The course is relevant for all fields of material science where structure on the nanoscale is important and for students aiming to use SAS in their project, for example polymer science, food science, plant science, nanoparticle research, soft matter physics, drug-delivery etc.
