Wilkening group @ ICTM in 2022; (c) AGW - TU Graz

Wilkening group

Workgroup of Professor H. Martin R. Wilkening at the Graz University of Technology

Solid-State Physical Chemistry and Energy Science

The Wilkening group focusses on the preparation, characterization and functionalization of new materials for modern energy storage systems. Emphasis is put on spectroscopic studies to shed light on micro- as well as macroscopic transport processes in crystalline, nanostructured as well as amorphous or glassy solids. In particular, we use solid state nuclear magnetic resonance (NMR) and conductivity spectroscopy to investigate short- as well as long-range ion dynamics in a variety of functional materials that are relevant for, e.g., battery applications.

Currently a Senior Researcher is working in the Wilkening group. Ass. Prof. Dr. Ilie Hanzu focusses on nanostructred and porous (MOFs) materials for energy storage.

H. Martin R. Wilkening (Head of the Institute, member of the Senate) studied chemistry at the University of Hannover where he completed his Ph.D. thesis (summa cum laude (ausgezeichnet), 2005) on "Ultraslow ionic motions in solids - NMR studies on lithium-ion conductors" under the supervision of Prof. i.R. Dr. Paul Heitjans. Subsequently, he was employed as a scientific co-worker in the same group and from 2008 as "Akademischer Rat a. Z.". In June 2011 he submitted his habilitation thesis to obtain the venia legendi in physical chemistry (mentor P. Heitjans). Shortly thereafter he accepted a full professorship at the Graz University of Technology (Austria) and received the venia docendi in solid state chemistry. In 2012 the Christian Doppler Laboratory for Battery Research was founded. Since 2016 HMR is director of the institute and served as a member of the senate of the TU Graz until 2022.
