Description

Nanofluidics, an emerging research area, attracts significant interest due to its unique behaviors and applications in separation, sensing, and energy conversion. Graphene, with its atomic thickness, stable chemical/mechanical properties, and the ability to be functionalized, serves as an ideal platform for studying nanofluid transport. We precisely controlled graphene pore sizes, which are crucial for optimizing transport properties. Functional group provides a new degree of freedom to further improve confined space within nanofluids. We further scaled up production, fabricating large-area graphene membranes for advanced instrument (membrane-based total organic carbon analyzers). Graphene nanopores also show promise for high-resolution sensors and fine-tuning nanofluidic transport. My group advances nanopore fabrication, elucidates mass transport mechanisms in graphene, and explores its use in practical applications.
