Nanomagnet compaction Why: The functionality of advanced materials depends on all length scales from the atomic level via nano-size and shape, to texture at the micrometer level. The research aim is to understand processes taking place, when nanoparticles are compacted into bulk materials. How: Specific instrumentation for investigating compaction processes of nanoparticles will be built and used in conjunction with large research facilities such as neutron and synchrotron sources. The neutron or X-ray radiation will provide detailed insight into the compaction process as it is taking place (in operando) What: Understanding compaction of nanoparticles is essential for utilizing the extraordinary nanoscale properties in bulk materials. The project may be a game changer for energy materials, where density is essential e.g. magnets, batteries, and thermoelectrics.
