In Situ Surface Reconstruction and Carbon Encapsulation for High‐Performance Pt‐Lean Catalysts beyond Conventional Core–Shell Designs

Small, EarlyView.
A one‐step in situ fabrication produces Pt‐segregated nanoparticles encapsulated in porous carbon shells. This design drastically reduces Pt content while maintaining high oxygen reduction reaction activity and long‐term durability. The catalyst meets DOE targets even at ultralow Pt loading, presenting a practical pathway toward cost‐effective, high ...

Tailorable Curie Temperature in Zinc Ferrite Nanoparticles With Finely Tunable Induction Heating Profiles Between Room Temperature and 250°C

Small, EarlyView.
A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable

Ion‐Regulating SPEEK–BNNS Hybrid Interfaces Enabling Low‐Barrier Zn‐Ion Transport and Dendrite‐Free Zinc Anodes

Small, EarlyView.
A scalable organic–inorganic hybrid protective layer composed of sulfonated poly(ether ether ketone) and boron nitride nanosheets is introduced to stabilize Zn‐metal anodes. The hybrid architecture regulates Zn2+ transport, suppresses dendrite growth, and mitigates parasitic reactions, enabling uniform Zn deposition and long‐term stable cycling in ...
