Summary: The improvement of micro-en-capsulated phase change materials (MEPCMs) through a three-step process has been shown to enhance thermal stability by forming a dense and durable Al2O3 shell, resulting in excellent heat storage capacity. By adjusting the amount of Al(OH)3 in the precipitation treatment, the thickness of the Al2O3 shell layer can be controlled, contributing to the high thermal durability and cycling stability of the MEPCMs.

Summary: Functional pavement materials, particularly phase change heat storage asphalt mixtures, are a focus of research. This study successfully developed a polyurethane-based solid-solid phase change material with suitable phase change temperatures and excellent cycling stability. By replacing limestone filler with this phase change material, the researchers were able to improve high-temperature stability and low-temperature cracking resistance in the asphalt mixtures, although water stability was weakened. These phase change mixtures showed promise in meeting pavement performance requirements.

Summary: This study proposes a temperature-adaptive design for passive radiative cooling (PRC) by integrating PRC with temperature control of room-temperature phase change material. The phase change material-enhanced radiative cooler (PCMRC) can adjust its performance according to the temperature of day and night, reducing the temperature difference between them. The PCMRC achieved an average subambient temperature drop of -6.3 degrees C under direct sunlight and an average temperature rise of -2.1 degrees C above ambient temperature at night, showing great promise for the regulation of passive radiative cooling.

Summary: In this study, optimal designs for rectangular Phase Change Material (PCM) modules charged by a water flow were obtained using topology optimization. The optimal topologies are designed to achieve maximum mean charging power of the PCM. Tree-like metal structures with increased branching were found to be more effective than straight fins in conduction driven phase-change problems.

Summary: This study demonstrates the impact of integrating eutectic Phase Change Material (PCM) in concrete on its thermal, physical, and mechanical properties. The researchers successfully prepared a Shape Stabilized Composite Phase Change Material (SSCPCM) by mixing eutectic PCM with Zeolite, which effectively prevented PCM leakage and showed stability in chemical, physical, and morphological properties. The integration of SSCPCM in concrete resulted in Thermal Energy Storage Concrete slabs, which exhibited excellent thermal behavior in real outdoor environments.
