Thermometric Based‐Microswimmers with Chemical and Optical Engines

Advanced Intelligent Systems, EarlyView.
Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...

Characteristics of Enhanced Heat Transfer of Nanofluid in Microchannels Under Electric and Magnetic Co‐Excitation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Due to its small size, microchannel heat exchangers are widely used in fine engineering fields such as electronic equipment. In this paper, the boiling heat transfer characteristics of refrigerants and nanofluids in microchannels are studied by applying electric fields, magnetic fields, and electromagnetic synergistic fields.
