Controlled Engineering of 2D Alkali‐Iron‐Chloride Compounds and Lateral Quantum Heterostructures Within Confined Graphene Nanoreactors

Advanced Functional Materials, EarlyView.
This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.

Improved dielectric and energy storage properties of three‐dimensional BaTiO3/polyvinyl alcohol‐boron nitride flexible dielectric composite via template infiltration strategy

IET Nanodielectrics
Continuous three‐dimensional BaTiO3 (3DBT) ceramic network was prepared by the sol‐gel method using cleanroom wipers as the template. Subsequently, flexible 3DBT/polyvinyl alcohol‐boron nitride nanosheets (PVA‐BNNS) composite dielectric films were ...

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...
