*3.4.2 Recent developments in CFT*

Researchers are innovating Cold Finger designs by integrating nanoparticles to enhance nucleation and combat supercooling, providing more effective nucleation sites. Focus has also been placed on refining temperature control within these setups to improve PCM efficacy. Customizing Cold Finger configurations to match the specific needs of different PCMs is key to optimizing phase change behavior. Hybrid approaches combining the Cold Finger Technique with other methods aim to offer comprehensive solutions. Efforts to adapt and optimize Cold Finger Techniques for thermal energy storage, incorporating renewable energy and ensuring grid stability, are underway. Advances in materials for Cold Finger components seek to improve durability and heat transfer, while developments in control and monitoring systems enhance understanding and optimization of PCM performance [81].
