New Bachelors Student Joins!

Welcome to our new bachelors student - Joana!

She will be learning microfluidic LC shell production and be working with Rao for the next few months Happy



GLCC @ Luxembourg is Fast Approaching!


The conference abstract booklets are all printed & ready to be distributed next week! Be sure to check the site: for updates, confirm meal selections, & know poster #s in advance. See you there!


New Paper in Materials by MDPI Journals

to Anshul & Jan on the publication in Materials: “Electrospun Composite Liquid Crystal Elastomer Fibers”!

This is the first study to date that shows and analyzes the irreversible actuation of photo-crosslinkable reactive mesogens single axially electrospun with a carrier polymer, to create liquid crystal elastomer (LCE) fibers. Don't forget to check out the supplementary info for more details!


New Paper in J. of Molecular Liquids

(Click the figure image above to access the article online, please email Jan if you cannot download the pdf file)

to JungHyun & Rao on the publication in the Journal of Molecular Liquids titled: “Sub-second dynamic phototuning of alignment in azodendrimer-doped nematic liquid crystal shells”!

For the 1st time(!!), a study documents the photoswitching of azodendrimer in liquid crystal shells produced by microfluidics. Ultimately, our group members & colleagues find that phase separation may occur in shells when the dendrimer is in the trans ground state, and that photo switching turns such shells uniform - further indicating that the cis state is better soluble in the LC.

Hooray for the good start to the 2018 year Laugh

(Fyi - Also, I think this paper is the 1st to show results obtained from our new confocal microscope as well…so HD, so cool)


New Langmuir Paper Released Online


(Click the graphical abstract image above to access the article online, please email either Jan or Rao if you cannot download the pdf file)

Congratulations to Larry & Rao on the publication in Langmuir titled: “Microfluidic Tensiometry Technique for the Characterization of the Interfacial Tension between Immiscible Liquids”!

This is Larry's 1st paper in our group (!) and also Rao's 1st time serving as last author on a paper (!)

In this study, Larry and Rao borrow inspiration from the biologists and use the novel technique of micropipette aspiration (commonly used to measure the viscoelastic properties of living cells) to measure the interfacial tension of 5CB, water, and surfactants with a high degree of accuracy (from the sub-millinewton per meter to several hundred millinewton per meter range) solely from experimental observations of the droplet deformation. This is highly unique as information on the liquid density is not needed to find the interfacial tension.


JPCM Review on LCs in Shells, Droplets & Fibers Makes IOP's 2017 Highlights!

Our review on LCs in Droplets, Shells & Fibers got selected for the 2017 highlights list by IOP Publishing!! Yes mega Congrats to our team!!

Thanks to everyone who also read &/or downloaded our article.
We put a lot of effort into trying to make a review as comprehensive, and as accurate, for those outside and in our fields as possible.

New paper in Advanced Optical Materials

Geng et al 2017 inside cover
**Update (12.01.17 - POM images fromYong's paper are selected for the inside cover of Advanced Optical Materials! Click the cover above to freely access the article online)

Congratulations to Yong on the publication in Adv. Opt. Mater. titled: “Through the Spherical Looking-Glass: Asymmetry Enables Multicolored Internal Reflection in Cholesteric Liquid Crystal Shells”!

Spheres of cholesteric liquid crystal generate dynamic patterns due to selective reflection from a helical structure subject to continuously curved boundaries. In this paper the patterns are investigated exclusively.

We're hosting the next German Liquid Crystal Conference in March 2018!

We are officially hosting the 45th German Liquid Crystal Conference this coming March 2018!


This will be a two-day conference on the physics, chemistry, applications & any other aspects of liquid crystals, held at the University of Luxembourg from March 21-23, 2018.

This is exciting for our group because it's going to be the 3rd time we host an international conference & it will be the largest one we've done yet. We are currently in close collaborations with groups in Belgium, the Netherlands, & France (note: this is not in competition with the the current French LC & soft matter society meetings).

Please check out the website for registration below!

Also, our Facebook Page for frequent updates for this year's meeting @

(FYI - Early bird deadline for registration and payment is
16th of February 2018!)

Hope to see you for fun talks on LCs in good ole Lux. this coming March!


Welcome to Anupam Sengupta! - Anupam will join the UniLu faculty in physics & materials sci.


Anupam received the ATTRACT Starting Investigator Grant 2016-17 for his project MBRACE - Microbial Biophysics of Rapid Adaptation in Changing Environments - with Jan Lagerwall as the local promotor. 

Anupam Sengupta will join the University of Luxembourg starting in the summer 2018 as an Assistant Professor in the Physics and Materials Science Research Unit. Using a cross-disciplinary approach, MBRACE will interface physics, biology, mathematics and engineering to study biological systems under changing environments, with a particular focus on order and topology inherent in living matter. Anupam holds a Dual Degree in Mechanical Engineering from the Indian Institute of Technology Bombay, India. He received a PhD in Physics for the thesis on Liquid Crystal Microfluidics, which he carried out at the Max Planck Institute for Dynamics and Self Organization, Göttingen, Germany 2009-2012. After a short postdoc in Göttingen, Anupam moved to MIT as a Human Frontiers Cross-Disciplinary Fellow to work on biophysical processes in marine environments. Since fall 2015, he is based at the Institute of Environmental Engineering, ETH Zurich, Switzerland. Here, in addition to marine ecology, Anupam works on microbial behaviour under low and hyper gravity conditions, and looks at bacterial dynamics in natural and nature-inspired ecosystems.

We hope to have future collaborations with him & his group once he arrives to Luxembourg!
