Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Electrical Resistivity Change Upon Crystallization as a Robust Descriptor for Metallic Glass Forming Ability

Advanced Materials, EarlyView.
Electrical resistivity change upon annealing is introduced as a rapid descriptor for identifying high glass‐forming ability in metallic glasses. High‐throughput combinatorial thin‐film libraries reveal that compositions exhibiting small resistivity changes correspond to sluggish crystallization behavior and known bulk metallic glass regions, enabling ...

Turning Humidity Into Function: Heterojunction Interfaces for Dual‐Mode Removal of Nonpolar Vapors

Advanced Materials Interfaces, EarlyView.
A wire‐grown MIL–88B(Fe)@Fe3(PO4)2 heterojunction converts ambient humidity into a functional mediator for nonpolar VOC purification. Water forms a hydration layer that enhances cyclohexane uptake while simultaneously promoting •OH generation, resulting in synergistic adsorption–photocatalysis under humid conditions.
