This paper was published in the latest issue of "Physics of Fluids" and is also featured in the recommended articles section on the journal’s official website. "Physics of Fluids" is a prestigious international journal in the fields of fluid and plasma physics published by the American Institute of Physics (AIP), and it highlights papers with significant academic contributions as "Editor's Pick."

This research was highly regarded for presenting a foundational technology that enables the precise measurement of key physical properties using extremely small fluid volumes of less than 50 microliters. In particular, it is expected to have wide applications across various precision processing and analysis technologies, including biofluids, polymers, pharmaceuticals, graphene, nanotubes, paints, and fibers.

Professor Heonsang Lee’s team conducted research to quantitatively analyze the subtle interactions between miscible fluids through experiments, theory, and computational fluid dynamics (CFD) simulations. Through this work, they identified a unique fluid flow mechanism called "wet-capillary-thinning (WCT)," attracting significant attention in the academic community.

Graduate students Ashar Husein and Kyungmin Choi led the research process from experiments to numerical analysis, data interpretation, and manuscript preparation. They enhanced the completeness of the research by deriving quantitative relationships among viscosity, osmotic pressure, effective diffusion coefficient, and nonequilibrium interfacial tension.

Professor Heonsang Lee stated, "The significance of this work lies in newly approaching and systematizing the interactions between microfluidic flows," and added, "I was deeply impressed by how the students completed the research to the end, demonstrating creativity and perseverance."
