[Soft-matter] Soft Matter and Stat Phys Seminar on 21 Jan 2022 [online only]

[Maciej Lisicki]

Dear Soft Matter Colleagues and Friends,

On Friday 21 January 2022 at 9:30 AM we are hosting a seminar during which

Jeffrey Everts (IChF PAN)

will give a talk

Manipulating ionic charges by flexing and melting orientational order

Abstract
The control and manipulation of electrical charge is of paramount importance for a wide variety of scientific disciplines. In this talk I address how ionic charge control can be achieved by using the orientational, i.e., liquid crystalline, order of materials. Liquid crystalline order occurs in many types of materials, which range from molecular to colloidal building blocks and (bio)polymers. Together with their possible applicability in energy storage, material science, device physics, microelectronics, and biology, it shows that the confluence of electrostatics with orientational order can lead to many interesting phenomena for a wide variety of systems. Specifically, we will demonstrate the manipulation of ionic charges by discussing anisotropic screening of charged colloid particles dispersed in nematic solvents, surface charge control mediated by liquid-crystal topological defects, and finally, the charging of point and line defects in nematic liquid crystals.

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.
