Microstructural evolution of SIMP steel during martensitic transformation

SIMP steel, a reduced activation ferritic/martensitic heat–resistant steel, is a promising candidate for structural applications in future nuclear fusion reactors. Understanding the evolution of microstructure in SIMP steel is of practical importance for improving the structural...

Hydrodynamic and mass transfer behaviors of NH 3 microbubbles in ionic liquids

Abstract Ionic liquids enable efficient ammonia‐containing gas separation, but conventional absorption towers suffer from limited interfacial area and mass transfer efficiency. Microchannels overcome this owing to their large specific surface area. This study investigated the hyd...

Antiphase Boundaries Regulate Phase Stability and Performance in DMA + ‐Assisted CsPbI 3 ‐Based Perovskites

ABSTRACT CsPbI 3 ‐based perovskites are promising absorbers for tandem solar cells owing to their optimal bandgap (∼1.7 eV). However, the phase transition from photoactive γ‐CsPbI 3 to non‐photoactive δ‐CsPbI 3 remains a major obstacle and is strongly governed by microstructural...

Lightweight All‐Solid‐State Pouch Cells Freed from High Stack Pressure

Since 2011, ionic conductivity of some sulfide- and halide-based solid-state electrolytes (SSEs) have already reached a level comparable to that of liquid electrolytes. Numerous companies worldwide have proposed diverse technical pathways for commercializing electric vehicles wit...
