Welcome
Soft Interfaces Laboratory (SIL)
Overviews
In our laboratory, we have been conducting various fundamental and applied research projects related to interfaces as well as applied research in energy, drag reduction, heat management, and flow control. Currently, the focal research areas in our lab include (1) creating new flow characteristics such as active turbulence and superfluid-like property using natural/artificial active particles for fluidic-thermal applications, (2) generating electrical energy utilizing nanoscale liquid transport phenomena for energy applications, and (3) understanding cytoplasmic within plant cells for biological applications. For detailed research topics, please refer to our papers or feel free to inquire via email.
