Highly Efficient and Stable Roll‐to‐Roll Coated Perovskite Solar Cells Enabled by Antisolvent Vapor‐Assisted Crystallization

Advanced Functional Materials, EarlyView.
Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

Biocompatible Conjugated Electrospinning Nanofibrous Membrane With Self‐Powered Piezoelectric Capacity for Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
A self‐powered PCL/gelatin‐PVDF‐TrFE/MXene conjugated electrospun membrane integrates biocompatibility with enhanced piezoelectric responsiveness. Mechanical deformation is converted into localized electrical signals that stimulate wound‐repair cells proliferation and migration, promote angiogenesis and tissue remodeling, and accelerate full‐thickness ...
