Surface science

Tuning wettability, design of anti-Ice and anti-fouling surfaces.

Wetting behavior of fluid-solid interfaces is of practical interest to technological important areas such as sensors, superhydrophobic and anti-ice surfaces. Wetting of patterned surfaces by liquids plays a key role in the fields of nano-fluidics and biophysics. Increase in demand of new nano-based technologies requires having a clear picture of wetting behavior on functional surfaces. Particular, the nature of functionalization and how the wetting behavior is affected is of considerable importance to the development of new materials. In this direction, we are studying the wetting transitions of polar and polymeric fluids on functional and textured surfaces using molecular modeling and simulations. Further, our interest is to understand the kinetics and thermodynanics of supercooled liquid on surfaces.
