Hybrid structures from nano-microscale to macroscale contribute to further manipulation of thermal-fluidic-energy transport making them useful in many applications. I will introduce ongoing researches utilizing thermal-fluidic-energy transports in hybrid structures. Topics will cover (1) Layer-by-Layer (LbL)-based coatings of porous structures for enhanced phase change heat transfer, (2) nanofluidic sensing of micro-nanomaterials using aqueous two-phase system, (3) active control of materials properties using structural and physicochemical transformation via the structure-guided combustion waves for the fabrication of energy materials, (4) local thermal energy control through thermal metamaterials using the manipulation of continuum heat transfer, (5) self-sustaining liquid-motion-sensing platform for continuous monitoring of dynamics using thermoelectrics and triboelectrics and (6) thermal analyses in hybrid systems, such as photo-thermal or electrical-thermal interaction.
