In his dissertation "NumericalModeling and Simulation of Lead-free Relaxor Ferroelectric Composites", a DFG project between the group of Prof. Kyle Webber (Friedrich Alexander University Erlangen) and IAM-MMI, Friedemann Streich developed a material law for constituent starting materials and implemented the theory in a finite element code. He succeeded in finding parameters for the starting materials that yield a composite effect in which the longitudinal large-signal piezoelectric coefficient is higher than for the starting materials. This provides important input for material developers on the way to optimized lead-free piezoceramics for actuators. Congrats!
The "European Network for the Mechanics of Matter at the Nano-Scale" (MecaNano) has been approved as a European Cooperation in Science and Technology (COST) for a period of four years. The IAM-MMI will also be part of MecaNano with Christoph Kirchlechner as the German representative.
MecaNano will offer its members numerous opportunities for interaction and collaboration and will be open to researchers from all countries.

Camila Aguiar Teixeira won the “Best Poster Award” of the Nanobrücken 2022 conference held at the Charles University (Prague). Camila presented her PhD study on slip of partial dislocations in high entropy alloys, for which she employed micro pillar compression with Transmission Kikuchi Diffraction (TKD) and STEM imaging. Parabéns!
An unique focused ion beam (FIB) microscope has been installed at our institute for the research programs “Information / P3T1”, “Materials and Technologies for Energy Transition” and “Fusion”, partly funded by the Robert Bosch Stiftungsprofessur for nanostructured functional materials.
