Porous Bi2S3 Bulk With Excellent Thermoelectric Performance by Solid States Replacement and Low Melting‐Point Metal Volatilization

Advanced Materials, EarlyView.
By introducing FeCoNi medium‐entropy alloy, the bismuth sulfide (Bi2S3) material achieves a record‐high ZT of 1.1 at 773 K, owing to the solid‐states replacement reaction and the volatilization of low melting‐point metal. This strategy is also applicable to other sulfur‐based thermoelectric materials.

Polystyrene/TiO2 Composite Thin Films by Powder Aerosol Deposition: Film Morphology Control Through Powder Processing

Advanced Materials Interfaces, EarlyView.
It's all in the mix! By employing different homogenization strategies for preparing polystyrene/TiO2 polymer‐ceramic composite (PCC) powders, we tune the morphology of PCC films obtained by powder aerosol deposition, ranging from segregated multilayer‐like to finely blended composites.

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

Advanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...
