Magnetoelectric BaTiO3/CoFe2O4 Thin‐Film Meshes for Neuronal Differentiation

Advanced Science, EarlyView.
We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Sol gel-derived rare earth-activated confined structures for photonics

, 2004
This paper deals with sol gel-based photonic structures, which allow to control and modify the optical and spectroscopic properties of rare earth ions. The most significant properties obtained for sol gel-derived planar waveguides and 1-D photonic band ...

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design

Advanced Science, EarlyView.
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Lactobacillus‐Loaded Bioadhesive Hydrogel with Prolonged Retention and Microenvironmental Remodeling for Endometrial Repair and Fertility Restoration

Advanced Science, EarlyView.
A bioactive adhesive hydrogel capable of long‐term uterine retention (>14 days) and local microenvironment modulation is developed by straightforward integration of α‐lipoic acid, L‐arginine, tannic acid, and Lactobacillus johnsonii, which can markedly enhance endometrial repair and restore fertility in a rat model of endometrial injury.

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 ...
