[Soft-matter] Soft Matter and Complex Systems Seminar on 14 April 2023

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 14 April 2023 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which we will hear 3 talks:

Russell Kajouri (IF PAN)

	Unidirectional Droplet Propulsion onto Gradient Brushes Without External Energy Supply

Durotaxis motion due to stiffness gradient is a process in which an agent, e.g.. a droplet or a cell, exhibits a unidirectional movement without consuming the energy of an external source. In our recent research, we describe the possibility of durotaxis motion of polymer-brush substrates and its dependence on various parameters. We also explain the mechanism of this phenomenon.

Soheil Arbabi (IF PAN)

	Coalescence of surfactant-laden droplets

Droplet coalescence is commonly encountered in nature and is also relevant for various technologies, such as inkjet printing. In this presentation, we present our results on the coalescence ofsurfactant-laden water droplets, which have been obtained by means of molecular dynamics simulation of a coarse-grained (CG) force-field. In particular, we will discuss the details of thecoalescence mechanism and the bridge growth dynamics.

Luis Carnevale (IF PAN)

	Liquid thread breakup and the formation of satellite droplets

The breakup of liquid threads into smaller droplets is a fundamental problem in fluid dynamics. Here, we estimate the characteristic wavelength of the breakup process by means of many-body dissipative particle dynamics and discuss the power-law dependence of the number of satellite droplets as a function of the Ohnesorge and thermal capillary number. We also elucidate the breakup mechanism and the conditions under satellite droplets form.

We warmly welcome everyone to attend the talk and the Soft Matter Coffee Break after the seminar, held in room 2.63 (2nd floor).
