Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Scalable Etch‐Free Transfer of Low‐Dimensional Materials From Metal Films to Diverse Substrates
Advanced Materials Interfaces, EarlyView.A scalable, etch‐free transfer method for low‐dimensional materials is presented, utilizing a low‐melting‐point metal as a reusable support. This technique enables gentle wafer‐scale electrochemical delamination from mechanically fragile metal thin‐film substrates and supports integration into device architectures.
