Dual-Layer Microencapsulated Phase Change Material Composite with Enthalpy-Active Shell for Thermal Absorption and Directional Heat Management

Abstract Localized heat accumulation in electronic devices degrades performance, safety, and cycle life. Phase change materials (PCMs) have been widely investigated for passive thermal regulation; however, conventional core–shell encapsulated PCMs often exhibit limited effective...

In Situ‐Grown Graphdiyne Interfaces on Cu‐Retained CoCuFe Phosphide‐Like Octahedra for Overall Water Splitting

ABSTRACT A Cu‐retention‐assisted precursor‐conversion strategy is developed to construct a graphdiyne (GDY)‐coupled CoCuFe phosphide‐like heterostructure for alkaline water electrolysis. Octahedral Cu 2 O directs the particle morphology and serves as a Cu source, whereas the CoFe...
