Nonmonotonic Enhancement of Electro‐Optic Properties of Wurtzite AlN Thin Films by Sc Doping

Advanced Electronic Materials, EarlyView.
EO coefficient, rc, for Sc‐AlN thin films in comparison with that for Mg ZnO thin films (left). Calculated electric field intensity of the fundamental mode supported by the active area that includes Sc‐AlN (right). ABSTRACT Wurtzite ferroelectrics, such as Sc‐doped AlN, have recently attracted considerable attention for their potential in realizing ...

Stable Magnetic Nanodomains Engineered Via Ga+‐ion Irradiation For Deterministic Sequential Switching

Advanced Electronic Materials, EarlyView.
Tiny magnetic regions separated by domain walls can store data, but controlling them precisely is difficult. We use focused ion beams to create nanoscale “anisotropy wells” that pin these walls from both sides. This bidirectional pinning holds domains stable in either direction, even with no field applied.

A Magnetically Programmable Metasurface for Versatile Scattering Manipulation in the Microwave Band

Advanced Electronic Materials, EarlyView.
A magnetically programmable metasurface converts external magnetic fields into microwave phase modulation, thereby removing surface bias wiring. This mechanism achieves both retro‐reflective beam control and radar scattering suppression, offering a contactless, barrier‐penetrating solution for on‐demand electromagnetic scattering reconfiguration ...

Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products

Advanced Energy Materials, EarlyView.
Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.
