"Isotropic-Isotropic phase separation and spinodal decomposition in liquid crystal-solvent mixtures" experimentally & theoretically reveals evidence of coexisting isotropic phases in simple mixtures of ethanol, 5CB, and water. Even though the nematic LC 5CB is arguably the most studied commercial liquid crystal worldwide, for the first time this study highlights experimental evidence of spinodal decomposition and nucleation and growth occuring between two isotropic phases and a single nematic phase between this common compound and equally common solvents.

Anjali works on forming liquid crystal shells and she works on trying to stabilize them using different surfactants and polymers.
Anjali and the team (Jampani, Nikolay and Jan from our group) + others from Prof. Ralf Stannarius's group in Magdeburg, Germany, observed LC shell behavior in a micro gravity environment made possible through several parabolic flights initiated in a plane provided by the German Aerospace Center (DLR)
Read about & see her experience here on the FNR's site: Spotlight on Young Researchers: Anjali Sharma
Anjali’s PhD is funded by the FNR’s PRIDE programme in the framework of the Doctoral Training Unit (DTU) MASSENA, which has the goal to improve the understanding and the performance of materials used in sensing and energy harvesting
She gave a brief presentation on what the group's research currently focuses on as a whole (see screenshots below). The research section of our site will soon be updated to reflect all of these projects.

His project is in collaboration with Prof. Gabriele Lenzini from the SNT (Interdisciplinary Center for Security, Reliability and Trust) & is funded by the FNR (the Luxembourg National Research Fund).
The project is called "SSH: Security in the Shell", more details can be found here

Welcome to our new interns Andy (left) and Ursa (right) who have joined our team.Andy will focus on Microfluidics for Measuring the Interfacial Tensions of Liquid Crystals. While Ursa will work on the Study of topological defect transformations in LC shells using a dual confocal microscope for controlled polymerization.
Congratulations to Anjali & Jan on the new publication in Liquid Crystals: "Influence of head group and chain length of surfactants used for stabilising liquid crystal shells"
This is the systematic study of the effect of different surfactants on Nematic LC shell, in terms of stability and alignment.
