She will be learning microfluidic LC shell production and be working with Rao for the next few months
The conference abstract booklets are all printed & ready to be distributed next week! Be sure to check the site: http://www.lcsoftmatter.com/glcc18lux/ for updates, confirm meal selections, & know poster #s in advance. See you there!
Congratulations 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!
Congratulations 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
(Fyi - Also, I think this paper is the 1st to show results obtained from our new confocal microscope as well…so HD, so cool)
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.
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.

Apologies for some errors while thew new site is getting updated.
Look out for new fixes in the new year.
See you in 2018!
You can contact Christina via e-mail here.
And don't worry, Jan isn't totally going to disappear from this site! (he is our PI after all) He's just getting his own personal site with all of his lectures up and running now too. Once it's ready I'll announce it on here. If you need to contact him though, you can still send him a message through the Contact page, or through his regular University of Luxembourg email address.
Finally, I just wanted to say that I think 2017 is going to be another great year for our group, full of new ideas & exciting research. It's my hope that the site can actually keep up with all the progress we make too.
*Toodles - A shortened anglicized version of the French phrase: à tout à l'heure, which generally means "see you later"
We will be in the "Tente parvis", at workshop 38: "Lumière fantastique!".
Also this summer we have the pleasure to host three students from the USA, within the framework of an NSF-funded IRES program devoted to liquid crystal fibers and filaments, headed by Prof. Tony Jakli at Kent State University (co-PIs are Prof. Margaret Frey, Cornell, and Prof. John West, Kent State University). This year our visitors are Emily Kerr, Aditi Naik and Vanessa Sanchez. Here you see them enjoying Luxembourgish Flammkuchen together with Jan and Catherine (who is the local group member working the most with them during their stay).
We finally have something that succinctly shows what our very multidisciplinary group does in the labs, & studies, on a regular basis.
What do you think?
& thanks to our very own Larry H. for the great design!
Variations of the logo will be available for download by group members on the Internal Site soon.
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 @ https://www.facebook.com/GLCC2018/
(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!
We live in polarizing times when it's become easier than ever to ostracize people just because they may think a bit differently, or look a bit differently, from us, but actually these individual traits can help our communities work and think better.
Have a look at our statement under the Team menu under On Diversity & Inclusion.
We're happy to welcome our new post-doc: Manos Anyfantakis! He officially joined the ESMP team at the start of July, and will mainly be working on advancing projects related to hydrodynamic flows, kinetic arrest, LC structure formation in the CNC work we have happening. He received his masters applied molecular spectroscopy in 2007, earned a phd in chemistry in Greece in 2010, and has since travelled to Germany and France for postdocs on the wetting of surfactant solutions and optofluidics phenomena before finally joining us in Luxembourg. You can contact Manos via e-mail here.
Welcome to both Anjali (left) and Shameek (right) who have joined our team as phd students starting in July.
Anjali will be working on making LC shells for advancing bio-related projects, while Shameek will be working on finding new polymers for advancing applications related to electrospun LC-fibers.
We have the pleasure to be hosting Ross Volpe, Ph.D. candidate, from Prof. Christopher Yakacki's group at the University of Denver, Colorado, USA, until August (the longest we've had a guest over yet!).
During his stay, he will mostly work with Rao on further advancing the actuation of micro shells & also start the development on actuating cylinders. We hope that these months will result in a great collaboration!
On May 10-12, 2017, our ESMP group and the Theory of Soft Condensed Matter Group (headed by Prof. Tanja Schilling) organized and held the Twisted Conference, bringing together many of the leaders, and newcomers, in the CNC and lyotropic liquid crystal fields. There were plenty of useful and interesting discussions on the physics, applications, and chemistry of cholesteric LC phases developing in colloidal suspensions of chiral nanorods. We thank all of the participants for actively engaging in our 2nd (ever!) conference we hosted. Another success
