Professor of Chemistry, Director of ICTM; @TUGraz we study ion dynamics in materials for energy storage by solid-state NMR, broadband conductivity spectroscopy
Fast ionic motion in a Na thiophosphate can drive structural change: using high-temperature Na-23 and P-31 #NMR up to 650 °C (@PANACEA_NMR), we show that Na-ion diffusion in Na4P2S6 precedes and initiates the transition to its rotor phase. JACS: https://t.co/osioiwTSKE
The bulk Na+ #ionic#conductivity of W-doped Na3SbS4 can reach an impressive 96 mS/cm at room temperature as extrapolated from low-T impedance spectroscopy down to – 160 °C; excellent agreement with diffusion coefficients from AIMD and QENS. JACS: https://t.co/YV4rXzCnxw
It was a pleasure to accept the invitation to join the podcast series by Radio IGEL. Interviewed by the students, we talked about chemistry, batteries, materials, and life. ;-) https://t.co/LkBQr9S2FX
We are excited to invite you to contribute to the upcoming International Conference on Electroceramics (ICE) by submitting an abstract. This conference will provide a dynamic platform to exchange ideas and showcase advances in the field of electroceramics. https://t.co/5l56FEs4y6
Looking forward to submissions: The Journal of Materials Science: Materials in Energy is a new multidisciplinary journal focusing on the latest applications of materials to energy devices for #conversion and #storage of different types of #energy.

Post-synthesis ball milling impacts the structure (see #NMR) and performance of LPS: shorter milling times optimize particle size and ion transport, while longer processing reduces conductivity. @ZeierLab shows how optimization works for #batteries: https://t.co/PLUnYUBAX8
Binary Li compounds as solid electrolytes: 1D and 2D Li(6,7) exchange #NMR revealed slow Li+ exchange between the Li2S and LiI environments in Li2S-LiI nanocomposites, see https://t.co/ZRbrwaTg0H Though detectable, it is by far not dictating overall conductivity here.
Increased Li+ hopping and ionic transport in Li2S-LiI (nano-)composites as revealed by conductivity spectroscopy in Anna's recent paper, see Small Science: https://t.co/ZRbrwaTg0H
#NMR measurements at temperatures as low as 9 K (cryogenic range) are needed to reveal details on Li ion hopping and spin-relaxation in argyrodite-type solid electrolytes: @ChemMater Great collaboration with W. Zeier's group @ZeierLab. https://t.co/8L700sf45O
We are looking for a new co-worker (#PhD_position) with experience in time-domain solid-state #NMR and/or conductivity spectroscopy. In our group (https://t.co/tDaFPW8gQW) NMR is used to understand #ion#dynamics in solid #electrolytes ... apply here: https://t.co/j03fp9x5zD
#Battery#Materials: Making visible Li+ displacements in LiFePO4 and unveiling the distinct phases within individual crystallites at unprecedented atomic-level resolution. Great collaboration between Ilie Hanzu and the team at Felmi, Adv. Energy Mater.: https://t.co/ulJROGBVZE
Mixed Conducting Interphases (MCI, a term coined by J. Janek) in solid electrolytes: read Thomas Scheiber's latest work (Li, Al, P, #NMR, ...) on lithiated LATP. Thanks to M. Finsgar for his great help with XPS. Adv. Funct. Mater.: https://t.co/jmQrInoRVX
