The energy transformation is a material's transformation

Human development has caused a depletion of natural energy and mineral resources and climate changes with non-predictable consequences. New energy concepts are required for the future of our industrial society resulting in e.g. an ever increasing emphasis on improving the efficiency of electricity transmission and utilization and in the progressive replacement of oil-based fuels in transportation by electric motors. Efficient cooling is another important challenge for our society. Humanity worried about keeping warm, now we will have to invest heavily into cooling as a basic necessity. In this context, Material Science has to make a major contribution.

Magnets for efficient energy conversion

We work on novel permanent and soft magnets, magneto- and elastocaloric and magnetostrictive materials as well as magnetic shape memory alloys and more generally on materials for efficient energy storage, transportation and conversion. They can enable a drastic and rapid reduction in CO2 emissions from the burning of fossil fuels or from the use of conventional refrigerants.

The development of new earth abundant materials for renewable energy technologies operating much closer to their physical limits requires novel processing routes, modelling on all length scales and advanced characterization techniques with high time and spatial resolution. We develop principle material design strategies and descriptors combined with high-throughput techniques by simulation and experiment. Additive manufacturing enables us to tailor and integrate local and sensing functionalities into devices and explore the concept of cyber-physical twins.

The great energy transformation is also a material´s transformation (“Die Energiewende ist eine Materialwende”). We study the reduction, substitution and recycling of critical materials on element, process and product levels as demand for strategic elements will multiply in the near future. Our graduates will be Material Science experts in this challenging field of research.
