Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

Advanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes

Advanced Materials, EarlyView.
Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Hydro‐Torsional Compaction for Scalable Production of Aramid Nanofiber Threads with Densely Assembled Double‐Helical Nanostructures

Advanced Materials, EarlyView.
This paper introduces a scalable strategy for producing hierarchically aligned PBDT threads through wet‐spinning, controlled drawing, and post‐spinning twisting. Ionic crosslinking reinforces structural stability, whereas alignment and twisting optimize mechanical performance.
