Layer Stacking Dependent Suppression of Metallicity and Superconductivity in Sr2IrO4/YBa2Cu3O7 Bilayers

open access: yesAdvanced Materials Interfaces, EarlyView.
Multilayers of insulators with a strong spin‐orbit coupling, like Sr2IrO4, and high temperature superconductors, like YBa2Cu3O7, hold great promises for new device concepts in quantum computing. Here, it is shown that the electronic properties of such multilayers are strongly affected by the mutual stacking order.

Quasielastic Neutron Scattering Reveals Anisotropic Water Transport in Smectite Thin Film

open access: yesAdvanced Materials Interfaces, EarlyView.
Clay minerals, vital in advanced technologies, exhibit tunable interfacial properties. Quasielastic neutron scattering is used on oriented beidellite films to study charge‐induced anisotropy. Results reveal anisotropic water dynamics and orientation‐dependent diffusion.

3D‐Printed Mixed Ionic‐Electronic Conductive Polymer Composites for Long‐Term Bioelectronic Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
This study demonstrates a formulation of polymer ink for 3D‐printable, conformable ECG patches for long‐term heart monitoring. The resulting electrodes exhibit high signal fidelity and stability, rivaling metal‐based probes after extended ambient storage.

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

open access: yesAdvanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

open access: yesAdvanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles

open access: yesAdvanced Optical Materials, EarlyView.
The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.
