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

Asia-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

Small 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 ...

Conversion of Waste to Sustainable Transport Fuel via Fischer–Tropsch Synthesis: Process Modeling and Life Cycle Analysis

Energy Science &Engineering, Volume 13, Issue 10, Page 4868-4885, October 2025.
ABSTRACT A lifecycle analysis was performed on a process for distributed forest residue collection and conversion into biocrude, followed by biocrude transport to a central facility and indirect liquefaction using Fischer–Tropsch synthesis with refining to sustainable aviation fuel (SAF).

Front Cover: Sustained and Enhanced Nucleate Boiling Using Hierarchical Architectures at Large Superheats (EXP2 5/2025)

Exploration, Volume 5, Issue 5, October 2025.
This paper illustrates a hierarchical nano‐/micro‐structured superhydrophilic surface that delays the Leidenfrost effect to 273 °C, enabling sustained boiling at extreme superheats. Counterintuitively, lower droplet impact velocity further postpones the Leidenfrost point by manipulating liquid‐solid impact dynamics, offering new strategies for high ...
