27.05.2020 Our article "Ionic liquid dynamics in nanoporous carbon: A pore-size- and temperature-dependent neutron spectroscopy study on supercapacitor materials" has been published as Editors' Suggestion in Physical Review Materials.

Ionic liquids imbibed in nanoporous carbons are promising hybrid materials for electrochemical energy storage, conversion and harvesting. These functionalities crucially depend on the ionic mobility in the pore space. Here we demonstrate that quasielastic neutron scattering, specifically the so-called fixed energy window experimental technique, is particularly suitable for a fast access of the confined ionic liquid’s dynamic landscape as a function of pore-size and temperature. Compared to the bulk we find reduced self-diffusion mobilities. However, despite this slowing-down, the temperature range of the liquid state upon nanoconfinement is remarkably extended to much lower temperatures, which is beneficial for potential technical applications of such liquid-infused solids.

20.11.2019 Study on the Self-Assembly of Liquid Crystals in Nanoporous Solids for Adaptive Photonic Metamaterials published in Nanoscale.

X-ray scattering and optical polarimetry evidence in agreement with Monte Carlo computer simulations that confinement-controlled self-assembly of liquid crystals in nanopores allows for designing photonic metamaterials with adaptive birefringence. Movies illustrating 3-D reciprocal space mapping of a nanopore-confined columnar liquid crystal based on synchrotron-based X-ray scattering along with the peculiar textures found in the study can be downloaded from the TORE repository of Hamburg University of Technology. This work is dedicated to Prof. Peter S. Pershan (Harvard University), a pioneer in the field of soft-condensed-matter physics, on his 85th birthday, remembering his mentoring in synchrotron-based X-ray scattering from liquids.
