Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,

Carbon Shell‐Encapsulated PtFe Catalysts in High Temperature Polymer Electrolyte Membrane Fuel Cells: Balancing Molecular Sieving and Diffusion for Enhanced Reactant Access

Advanced Functional Materials, EarlyView.
Scanning electrochemical microscopy reveals reactant diffusion through porous carbon shells to PtFe cores, while the carbon‐encapsulated PtFe enables high‐performance HT‐PEMFC operation by sieving phosphate ions that induce catalyst poisoning. ABSTRACT High‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) operating at 160°C on phosphoric

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

Advanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.
