Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

Small, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Role of 1D and 2D Materials in Achieving Transparent and Flexible Lithium‐Ion Batteries for Wearable Electronics

Small, EarlyView.
Hybrid 1D–2D architectures redefine material design strategies for TFLIBs by decoupling competing performance parameters. This approach accelerates the transition of TFLIBs from proof of concept to practical wearable technologies. ABSTRACT Transparent and flexible lithium‐ion batteries (TFLIBs), enabled by advanced nanomaterials and flexible ...
