[Soft-matter] Soft Matter and Stat Phys Seminar on 18 Mar 2022 [online]

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 18 March 2022 at 9:30AM we are hosting a seminar during which

Mateusz Denys (IF PAN)

will give a talk

How surfactants affect cloud droplet activation?

Abstract
Atmospheric aerosols usually consist of inorganic salts and organic substances, where a significant part is surfactants, that is, amphiphilic molecules containing a hydrophilic and a hydrophobic part. Due to their amphiphilic character, surfactants preferentially adsorb at the surface of liquids lowering the surface tension of the interfaces, thus affecting processes, such as droplet coalescence, development of precipitation and (ultimately) cloud lifetime. 

We created a numerical model of cloud droplet formation with a presence of surfactant and salt. The model is based on the Lagrangian particle-based microphysics scheme Super-Droplet Method (SDM). By means of the SDM, we provided an evidence that surfactants influence cloud formation.

The seminar will be conducted on Zoom
https://us02web.zoom.us/j/82784273907 <https://us02web.zoom.us/j/82784273907>
and will begin at 9:30AM. 

For future talks, we will most likely be back to stationary (in person) seminars in April.
