3rd International Symposium on the Frontiers of Functional Materials Research
Date & Time:

13:00 – 17: 30, April 8th, 2024

Place:

Graduate School of Environmental Studies (J22), 4F Lecture Room 5

It is easy to make bad devices out of good materials, but impossible to make good devices with badmaterials. Materials always come first. In this symposium, we invite the world leading scientists todiscuss the state-of-the-art research on functional materials for e.g., batteries, solar cells,thermoelectrics, fuel cells, and other energy related materials.
This time, we invite Prof. Wolfgang G. Zeier from the University of Münster, Germany, to discuss
recent topics in solid-state batteries and related materials and provide an opportunity to exchange
research ideas and perspectives with young researchers and students at Tohoku University.

Closing remark

Wolfgang Zeier received his doctorate from the University of Mainz in
2013, followed by postdoctoral stays at the University of Southern
California, the California Institute of Technology, and Northwestern
University. After leading an independent research group at theUniversity of Giessen, he now holds a professorship for inorganic solidstate chemistry at the University of Münster. In addition, he heads adepartment at the Helmholtz-Institute Münster, Ionics in Energy
Storage. His research interests encompass the fundamental structure–property relationships in solids, with a focus on thermoelectric and ionconducting materials, as well as solid–solid interfacial chemistry for allsolid-state batteries.
