Soft Matter Group
The Soft Matter group is a group within the Laboratory for Neutron Scattering and Imaging (LNS), Paul Scherrer Institute (PSI), Division Research with Neutrons and Muons (NUM).
We run the dedicated user instruments at the spallation neutron source SINQ:
| SANS I | small angle scattering | 6.10-4 Å-1 < q < 1.05 Å-1, polarisation |
|---|---|---|
| SANS II | small angle scattering | 2.10-3 Å-1 < q < 0.35 Å-1 |
| AMOR | vertical TOF reflectometer | polarisation option |
| ECHO | USANS, double crystal diffractometer | option on Morpheus |
and the test / in-house beamlines
| MORPHEUS | polarised 4-circle diffractometer | test instrument |
|---|---|---|
| NARZISS | polarised reflectometer | in-house, neutron optics |
We are doing research in various fields connected to hard and soft condensed matter physics. We focus on structure and dynamics in materials with relevant length scales in the nm-range. Here are some examples:
- Nanomagnetic Structures
- Nano-Capsule Dispersions as Drug Carrier
- Polymer surface submicro-dots and colloidal covering
- Adsorption of Biomolecules at Interfaces
- Multilayers
- Magnetic induction at interfaces
- Improvement of Fe/Si based neutron polarisers
- Concepts to tailor the interface quality in neutron optical devices
- Structure of Proteins in Solution
- Domain Structure in Polymer Membranes for Fuel Cells
- Microgels
- Melting of crystals in 2D
- Nucleation and growth of colloidal crystals
