Lecture by professor Nikolay Priezjev on wetting properties of structured surfaces explored by MD simulations

On Friday, June 8, seminar "Supercomputer and Multiscale Modelling of Condensed Phase and Biological Systems" was held. Professor Nikolay Piezjev gave a talk on investigation of wetting properties of of structured interfaces in 2 parts.

Professor N. Priezjev describes molecular dynamics model used in this work.

The properties of so-called superomniphobic (i.e. hydrophobic and lipophobic simualteneously) surface was studied via two different modeling approaches. First, we used atomistic simulations of the liquid usling Lennrad-Jones and FENE potentials. Second, continuum simulations of the liquid-vacuum and liquid-surface interfaces were performed using Surface Evolver software. Surprizingly, these approaches gave the same results in terms of critiacal pressure dependance on the wetting angle and surface tension.
