[DBS lunch seminar] Uroš Tkalec: “From microcargo transport at liquid crystal/water interfaces to volumetric microscopy of anisotropic fluids”

30. March, 2023 at 14:00 - 15:30

Abstract

Microcargo transport between immiscible fluids, usually water and unstructured oils, is a physical process essential in adsorption and separation, emulsification, liquid-liquid extraction, and drug delivery. However, in conventional water-oil systems, it is difficult to manipulate the direction of cargo transport from one liquid to another. To address these issues, we have designed a series of drop impact experiments with liquid crystal interfaces where we can selectively trigger mass transport by tuning the mesophases and post-impact dynamics. To study such phenomena in more detail, we aim to explore the potential of quantitative volumetric microscopy based on the principle of holography. Recently, numerous advances have been made in optical imaging of anisotropic fluids, including stimulated emission depletion, and light sheet microscopy. However, these modalities are not label-free and are generaly not fast enough to follow dynamic processes. Therefore, we will develop an experimental setup for digital holographic microscopy to quantify the morphology and spatial refractive index distribution of anisotropic fluids at microscale interfaces.

Event information

The seminar will take place at 14h in the seminar room of physics (106) in the main building of Jožef Stefan Institute. The seminar will start with a snack (pizza) and will be followed by an informal discussion.
