Outline of Final Research Achievements

Steady progress is being made in academic research on the formation of structures, the elucidation of physical properties, and the expression of new functions in the field of micro- and nanotechnology. These studies have the potential to bring about significant innovations not only in the fields of electronics, information, and communications, but also in the fields of environment and energy. In this study, we created novel functional microcapsule particles by advancing microencapsulation technology, and developed a micro-scale ultra-efficient heat exchange device by integrating it with state-of-the-art latent heat storage technology. Specifically, multifunctional capsules doped with thermosensitive magnetic particles and phase change materials (PCMs) are created. Furthermore, the fundamental mechanism of highly efficient heat transfer between the dispersion medium containing the capsule and the tube wall is elucidated.
