SANS in Soft Matter: From Principles to a Case Study

by Marcello Demitri (TUM)

Monday 1 Jun 2026, 14:30 → 15:30 Europe/Berlin

PH HS 3 (Physics Department)

This seminar talk is divided in three parts: 

in the first part there will be an introduction on some theoretical aspects important for the study of soft matter via neutron scattering: among others, the scattering vector, scattering length density, form factors, structure factors, and correlation functions will be discussed. 

In the second part, after briefly placing SANS within the broader family of neutron scattering techniques, the focus will be on its basic principles, experimental setup, and relevance for probing nanoscale structures.

In the last part the paper "Effects of Polymer Block Length Asymmetry and Temperature on the Nanoscale Morphology of Thermoresponsive Double Hydrophilic Block Copolymers in Aqueous Solutions" will be discussed, focusing on the aim of the study, the SANS-based analysis and the theoretical tools used to interpret the results, building on the concepts introduced in the first two parts of the seminar talk.
