3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

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.

Field emission effect in triboelectric nanogenerators. [PDF]

Nat Commun
Abstract Triboelectric nanogenerators (TENGs) have garnered increasing attention due to their exceptional ability to convert mechanical energy into electricity. Previous understanding is that the electric performance of TENGs is primarily restricted by contact electrification, air breakdown, and dielectric breakdown effects.
