Thermal hysteresis in phase-change materials: Encapsulated metal alloy core-shell microparticles

Thermal Hysteresis in Phase-Change Materials was investigated based on alloy core-shell microparticles. The TH was found to be affected by the ramping rate in differential scanning calorimetry, the shell thermal resistance and the required temperature for heterogeneous nucleation. The study provided guidelines to modulate the TH of PCMs, and the concept learned from this study can be applied to enhancing the thermal energy storage in various thermal systems.183
