CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings
Heat Transfer, EarlyView.ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Spinel Aluminate‐Based Heterojunctions as Photocatalyst: A Review
ChemistryOpen, EarlyView.Spinel aluminates (MAl2O4; M = Zn, Mg, Ca, Sr) serve as robust platforms for designing heterojunction photocatalysts. Their stable lattices, tunable band structures, and efficient charge transport enable improved light‐driven carrier separation, significantly enhancing pollutant degradation efficiency in advanced photocatalytic systems.
