Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, EarlyView.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.

On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions
Advanced Materials, EarlyView.We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.
