Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Proximity Induced Magnetic Anisotropy and Trefoil Fermiology in Monolayer FeCl2/Bi(111)
Reorientation of magnetic anisotropy in a 2D van der Waals magnet is demonstrated in monolayer FeCl2 epitaxially grown on a bismuth substrate, from its natural out‐of‐plane direction to a predominantly in‐plane orientation. The FeCl2/bismuth heterostructure exhibits moiré‐induced interface states, suggesting strong coupling at the interface.

Self‐Oscillating Helix Showing Amplified Winding and Unwinding Motions
The hydrogel helix exhibits autonomous oscillation synchronized with the Ru(bpy)32+/3+ redox cycle in the Belousov–Zhabotinsky reaction. Periodic winding–unwinding accompanies magnified motion along one direction within the gel phase. ABSTRACT Helical architectures in nature amplify motion via winding–unwinding.

Device‐level zinc batteries are energy‐limited by the mass/volume of inactive components, while lean‐electrolyte operation triggers interfacial water depletion and unstable kinetics. Here we elucidate lean‐failure mechanisms and develop a COF@PAN functional separator that regulates hydrogen‐bonding networks to manage water activity and accelerate ...
