[Soft-matter] Soft Matter and Stat Phys Seminar on 22 Apr 2022

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 22 April 2022 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which

Panagiotis Theodorakis (IF PAN)

will give a talk

Pinning and its role in the directed motion of fluids

Abstract
Pinning of liquid droplets on solid substrates is ubiquitous and plays an essential role in many applications, especially in various areas such as microfluidics and biology. In some cases, this phenomenon can offer new possibilities for technological exploitation, while in other cases it can pose challenges. In this talk, I will discuss the details of pinning and depinning processes in the case of liquid droplets on solid substrates and possible ways of exploitation. Then, I will present our results and analysis on the rugotaxis phenomenon, that is, the spontaneous motion of a fluid onto wavy substrates with gradient in the wavelength, and discuss the role of pinning. Our analysis is based on molecular dynamics simulations of a coarse-grained model.

We warmly welcome everyone to attend the talk and the Soft Matter Coffee Break after the seminar, held in room 4.51 (4th floor).
