Armin Feldhoff

Armin Feldhoff is an Extraordinary Professor (apl. Prof.) at the Faculty of Natural Sciences of the Leibniz University Hannover, leading the Thermo-Iono-Electronic Materials and Microstructure Analysis Group within the Institute of Physical Chemistry and Electrochemistry. He has held this position since 2012 and also serves as Department Student Advisor for the Chemistry M.Sc./M.Ed. program.

• Academic Career:
  • Habilitation in Physical Chemistry (2009), Leibniz University Hannover
  • Ph.D. in Physics (1997), Martin Luther University Halle-Wittenberg
  • Diploma in Physics (1994), Westfälische Wilhelms-University Münster

His research focuses on thermoelectric materials, mixed ionic-electronic conductors, and oxygen transport membranes, with expertise in high-resolution electron microscopy (HRTEM, EFTEM, STEM-HAADF) and X-ray diffraction. He has developed advanced ceramic composites for energy harvesting and CO2 conversion systems, emphasizing microstructure engineering and material sustainability.

Recent publications highlight trends in:

• Textured and asymmetric ceramic membranes
• Electrospun nanoribbons for thermoelectrics
• Spark plasma sintering/texturing techniques
• Microemulsion-based synthesis
• Hydrogen-tolerant oxygen transport systems
• Mixed-phase stability analysis

Scientific awards include the ACerS Global Ambassador (2022), DT Rankin Award (2022), and Luther Medal (1998). He serves on editorial boards for the Journal of the American Ceramic Society, Entropy, and Energy Harvesting and Systems.
