Joint Research Activities (JRA) focus on the development of the advanced TEM methods required for the solution of key problems in materials and nanoscience. Importantly, these JRA will strengthen TA capabilities within the ESTEEM3 consortium by providing a higher level of overall service to all TA users both from academia and industry. The JRA have been selected to enable potentially disruptive scientific and technological projects that will enhance overall service provision. In addition, we have structured a JRA to tackle key problems in technologically important materials.
