**3.4 Addressing supercooling challenges using the Cold Finger Technique (CFT)**

The CFT is an innovative method aimed at mitigating supercooling in PCMs, ensuring their solidification at or near the intended phase change temperature. Praised for its simplicity and reliability over extended periods, CFT finds application in various sectors including energy storage, HVAC, and refrigeration, where precise temperature control and phase change efficiency are critical. Its versatility allows for customization to meet specific PCM temperature requirements and adapt to unique industry demands, highlighting its importance in improving thermal management and energy efficiency across a broad spectrum of applications [32].
