Congratulations to Larry, Shameek, Manos, and Jan on their recent publication, "Elastic Sheath–Liquid Crystal Core Fibres Achieved by Microfluidic Wet Spinning" published recently in the Journal of Materials Chemistry C!
In this article, they present the wet spinning of core–sheath liquid crystal-filled elastomer fibers using a microfluidic spinneret adapted from the normal techniques they use to produce shells and droplets. In particular, when we spin fibers containing a cholesteric liquid crystal, the result showing brilliant reflected colors as a result of the liquid crystal alignment within the fiber core. These fibers can be highly stretchable and show color changes upon heating and cooling.
You can access the article here.

Congratulations to Anjali, Jampani, and Jan on their new article published in Langmuir: "Realignment of liquid crystal shells driven by temperature-dependent surfactant solubility"
This is the study of nematic LC shells stabilized by temperature responsive surfactant. Study shows how one can change the alignment of LC just by varying the temperature. Click here for the full article.

Anjali gets featured on FNR's Spotlight on Young Researchers!
28/06/19 17:47
Our Ph.D student Anjali Sharma was featured on FNR's Spotlight on Young Researchers blog! 
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)

New Study on 5CB-Ethanol Phase Separation in Soft Matter + Cover!
29/06/19 17:18
Congratulations to Catherine and Jan on the new publication RSC's Soft Matter:
"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.
