Multi-scale materials

Most materials and minerals have hierarchical structures, with grains and domains down to atomic-scale defects. We create new ways of mapping these structures and their dynamics at and between these different length scales. This gives us the ability to make 3D movies of complex, multi-scale materials processes in real time, ultimately allowing us to develop better approaches for optimizing materials and their applications.

Researching materials and methods

We cover a broad range of materials and applications of fundamental relevance:

  • Deformation and annealing processes in metals.
  • Defect and domain topologies in ferroic and functional oxides

At the same time, we also develop the x-ray and neutron instrumentation used for characterizing them:

  • Optics for high-resolution x-ray and neutron imaging
  • Coherent x-ray imaging methods
  • Software for 6D reconstructions of microscopy data Previously, our developments have included novel multi-scale techniques, such as 3D X-Ray Diffraction (3DXRD), Dark-Field X-Ray Microscopy (DFXRM) and Hard X-Ray Microscopy (HXRM).

International facilities

Seeing inside materials often requires beams of intense, high-quality x-rays or neutrons that can penetrate large or embedded structures. Most of our experiments take place at large-scale facilities around the world, including:

  • European Synchrotron Radiation Facility (Grenoble, France)
  • MAXIV Synchrotron (Lund, Sweden)
  • European Spallation Source (Lund, Sweden)


We continually have new projects suitable on a variety of topics suitable for all levels, including Bachelor, M.Sc., Ph.D. and Postocs. If you are interested, please contact us.
