This study introduces a novel theory to evaluate the generation of complex emulsions. It demonstrates that an applied electric field significantly improves production efficiency and monodispersity, allowing for flexible control over droplet size and core-shell structures. Using this method, the research successfully fabricates organic microcapsules containing phase-change materials, which can be integrated into lithium-ion battery electrolytes to provide an effective temperature-buffering function. This work advances the understanding of colloidal systems and paves the way for functional materials in energy management and related fields.

This work has developed a data-driven framework to co-optimize slip boundaries and rib microstructures for advanced microfluidic cooling. The work demonstrates that the slip effect enhances heat transfer while reducing flow resistance. By integrating deep learning with genetic algorithms, an optimal design was pinpointed, achieving a 65.1% reduction in peak temperature rise. This approach provides an intelligent strategy for thermal management in next-generation, high-power-density electronics.

New research systematically reveals how hydrophobic surfaces alter flow and heat transfer in microchannel entrance regions. By correlating entrance lengths with Reynolds number and slip length, the study shows slip can cut flow resistance by up to 80.1% while boosting convective heat transfer by 52.1%. A critical coefficient αc is introduced to guide surface designs that achieve both drag reduction and thermal enhancement. The findings provide a predictive framework for optimizing next‑generation microscale cooling systems.

We have created silicon-based microfluidic chips that integrate tunable surface wettability (from 21.8° to 164.0°) with droplet-shaped microstructures to address the trade-off between drag reduction and heat transfer in micro-cooling. While superhydrophobic channels cut drag by up to 48.6% at a heat-transfer cost, hydrophilic channels with specific microstructures uniquely enhance heat transfer by 31.6% while also reducing drag. Simulations reveal the underlying slip-length and resistance mechanisms. This integrated platform provides a scalable path for designing adaptive cooling in high-density electronics.

In this work, we conducted a systematical investigation on the flow characteristics of non-Newtonian flow at microscale targeting on the coupling effect of the non-Newtonian shear thinning effect and cavitation structures for flow resistance reduction, where both the flow characteristics and the detailed flow fields were measured by means of self-built high speed micro Particle Image Velocimetry (micro-PIV).
