Dynamic Mosaicity Modulates Ion Transport in Stimuli‐Responsive Liquid Crystal Electrolytes

open access: yesAdvanced Science, EarlyView.
Thermotropic ionic liquid crystals provide a tunable platform for dimensionally‐controlled soft electrolytes, where anisotropy, nanoconfinement, and dynamic mosaicity govern ion transport behavior. In situ and operando analyses reveal a direct correlation between dynamic mosaicity and mesoscopic conductivity.

Magnetically Compensated Nanometer‐Thin Ga‐Substituted Yttrium Iron Garnet (Ga:YIG) Films with Robust Perpendicular Magnetic Anisotropy

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports on the remanent magnetization 4πMr and the temperature dependence of the net magnetization of magnetically compensated Ga:YIG films. For samples with very low net magnetic moments, the compensation points Tcomp and the Curie temperatures TC are determined. Ga:YIG films exhibit a significant increase in effective magnetization 4πMeff,

Understanding the Relevance of Percolation on Charge Transport in Random ZnO Nanowire Networks

open access: yesAdvanced Electronic Materials, EarlyView.
Conductivity in random nanowire networks remains challenging due to arbitrary geometries and conduction pathways. An innovative universalized percolation model combined with a shortest‐path algorithm addresses these limitations, accurately capturing tunneling and percolative conduction in ZnO nanowires.

In Situ Diffraction and Ex Situ Transmission X‐Ray Microscopy Studies of Solid‐State Upcycling for NMC Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
Description of attached TOC figure: Phase evolution observed from in situ X‐ray diffraction experiments during upcycling of NMC622 is shown in a contour plot in the center. 3D nickel XANES maps generated using variable energy transmission X‐ray microscopy are presented on the left and right to capture the change in the distribution of nickel during ...

Connecting Local Structure, Strain and Ionic Transport in the Fast Sodium Ion Conductor Na11+xSn2+xP1−xS12

open access: yesAdvanced Energy Materials, EarlyView.
Substitution by larger polyanions in the fast sodium ion conductor Na11+xSn2+xP1−xS12 leads to inhomogeneities in the local structure which induces micro strain. The observed strain correlates with higher local diffusivities at room temperature and a lowering of the activation barriers for local ionic jumps which is explained by a widening of ...
