Artificial Grain Boundaries Created by Freestanding Membrane Transfer Reveal Angle‐Dependent Ferroelectric Switching and Leakage in BaTiO3

Advanced Science, EarlyView.
Artificial grain boundaries are created in BaTiO3$\text{BaTiO}_3$ thin films by freestanding membrane transfer, enabling direct isolation of a single boundary. Local ferroelectric switching and leakage are found to concentrate at the grain boundary, while increasing misorientation systematically enhances conduction.

Organic Nanozyme‐Embedded Biotherapeutic Thermosensitive Hydrogel for Extracellular GSH Depletion and Postoperative Tumor Suppression

Advanced Science, EarlyView.
A temperature‐sensitive hydrogel loaded with cyanine nanozymes and Escherichia coli is locally injected into postoperative tumor resection beds. Upon light irradiation, synergistic PTT and PDT work with cascaded reactive oxygen species to deplete extracellular GSH, eliminate residual tumor cells, and induce robust antitumor immune responses for ...
