Prof. Max Wolff explores meso-scale materials through neutron scattering

On January 18, Professor Max Wolff from Uppsala University (Neutron Scattering, Division for Materials Physics, Department of Physics and Astronomy) delivered an insightful presentation on "Materials on the meso-scale: The neutrons view" at the Institute of Solid State Physics, University of Latvia. The lecture delved into the intricacies of soft and hybrid materials, utilizing neutron scattering methods to analyze their properties.

Prof. Wolff discussed two material systems, starting with polymers known for their viscoelastic properties applicable in various technological domains. The presentation highlighted non-linear responses at the molecular level and the implications of binding energies close to ambient thermal energies.

The discussion further explored macroscopic flow instabilities in polymer systems, revealing connections between self-assembly, topological interactions, and viscoelastic properties. Experimental results on macroscopic flow instabilities complemented these findings.

The second material system examined was magnetic liquids, offering versatility in manipulating interactions between constituents. Prof. Wolff shared insights into controlling self-assembly and crafting structures through a bottom-up approach, summarizing results from a two-dimensional binary magnetic liquid with diverse phase formations.

Throughout the lecture, neutron scattering methods were emphasized for their crucial role in providing essential information. In conclusion, Prof. Wolff briefly discussed potential benefits arising from the European Spallation Source, offering a glimpse into future research opportunities.

Attendees gained a deeper understanding of meso-scale material intricacies and the significant role neutron scattering methods play in advancing the field of materials physics.
