Multiscale Materials Characterization

We explore the structure of materials across multiple length scales — from the molecular level to bulk materials. Using X-ray and neutron-based imaging and scattering techniques, we address scientific and industrial challenges in a wide range of fields.

Research group description

Our research group focuses on the structural characterization of materials across multiple length scales, from the molecular to the macroscopic. We investigate the internal architecture of various materials using advanced imaging and scattering techniques, primarily based on X-rays and neutrons. We operate an open-access X-ray tomography laboratory for non-invasive, three-dimensional imaging of microstructures and use X-ray and neutron scattering to probe nanostructures. In parallel, we develop and refine these methods to enhance their accuracy and adapt them to diverse research needs. By uncovering the micro- and nanostructure of materials — such as wood-based materials and soils — and their interactions with factors like moisture, we help solve challenges in both scientific research and industrial applications.
