Why Neutron Scattering is Important?
Neutron scattering is a unique tool that allows scientists to probe the inner workings of materials and understand how they behave on a molecular level. It’s particularly useful for studying materials that are difficult to analyze using other techniques, such as liquids, glasses and polymers. Some key benefits of neutron scattering include:
- High sensitivity to light elements such as hydrogen and lithium.
- Ability to study materials in their natural state, without the need for chemical modification.
- Highly accurate measurements of atomic and molecular structures.
- Ability to explore dynamic processes such as diffusion and phase transitions.
Exploring the Universe at the Nanoscale through Neutron Scattering and Molecular Dynamics
The workgroup is using different neutron scattering methods like small angle scattering, neutron spectroscopy and neutron diffraction in combination with structural modeling and molecular dynamics simulations to study the structure and dynamics of biomolecules and membranes, mainly in the field of photosynthesis research. We are leading the development of time-resolved neutron scattering methods and techniques with in-situ illumination of materials.
In addition, we investigate other types of solid matter including different smart materials like UV-curable polymers, dental materials, food and milk proteins.
The group’s research spans photosynthesis, biomolecular systems and advanced materials, including smart polymers, dental materials and food proteins.
Main Research Directions
- Investigations of photoswitchable proteins and membranes like the orange carotenoid protein (OCP) are carried out aiming at the determination of the active state structures and their molecular flexibility.
- Solution structures of native photosystems PSI and PSII are explored using small angle scattering under nearly physiological conditions as employed for functional studies and biotechnological applications. The method is also used to improve the conditions of detergent-solubilization and crystal formation to obtain high-resolution structures.
- Photosynthetic light-harvesting complexes are studied by neutron spectroscopy to achieve a better understanding of the capture of solar energy under physiological conditions.

The workgroup also develops infrastructure for the European Spallation Source (ESS) as part of the Estonian in-kind contributions (see www.ess.eu). This concerns mainly the development of pump-probe experiments with optical activation of biological processes and subsequent time-resolved test of the related protein structure and dynamics.
