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

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 20, Issue 6, November/December 2025.
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.

Durable Nonfluorinated Stochastically Hierarchical Superhydrophobic Interface for Intense Long‐Term Phase Change Cooling

open access: yesSmall Structures, Volume 6, Issue 11, November 2025.
A novel six‐step strategy is developed for fabrication of durable stochastically hierarchical superhydrophobic boiling interfaces. The engineered interfacial properties effectively mitigate the loss of superhydrophobicity that occurs on copper during long‐term boiling, overcoming a key barrier to practical deployment in advanced phase change cooling ...
