The ESMP group hosted the 2026 German Liquid Crystal Conference (GLCC 2026) on the Belval campus of University of Luxembourg, 8-10th of April 2026. As it followed on our first ALCEMIST workshop most team members were present also at the conference, showcasing the project in several ways. Jan Lagerwall was the chair and main organizer of the conference, Lena Godinho was one of the invited speakers and also represented southern Europe as well as the International Liquid Crystal Society during a panel discussion on future directions for liquid crystal research in Europe, and Eugene gave the laudatio to Prof. Rudolf Zentel at the ceremony where Rudolf received the Saupe medal from the German Liquid Crystal Society.






As icing on the cake, Miriam and Tatiana were awarded a best poster prize for their work on shear-aligned large-scale liquid crystal elastomer actuator sheets. And everyone participated in the organization, discussions and in ensuring a good atmosphere and a successful meeting in general.

On 7th of April 2026, the first ALCEMIST workshop took place, this time gathering the entire team (except one PhD student who unfortunately fell ill). The workshop was organized in Luxembourg, this time on the new Belval campus of the University of Luxembourg, as we took advantage of the fact that the ESMP group was organizing the German Liquid Crystal Conference 2026 (GLCC) on the same campus, 8-10th of April, allowing ALCEMIST to be showcased also at the conference (where one example of ALCEMIST research won a best poster prize).


At the workshop we presented the recent advances in all three scientific work packages. As highlights we may mention:

• WP 1: The Nova team perfected their method to synthesize butyrate hydroxypropylcellulose (BPC) and can now provide all team members with tens of grams each. The BPC can easily be shear-aligned for uniform non-helical arrangement and the team also demonstrated a method for getting uniform structural color from BPC films across 100 square cm areas and showed that the color can be tuned across the full visible spectrum.
  
• WP 1: The Cambridge team showed revealing experiments with mesogen-functionalized styrene-butadiene-styrene (SBS), demonstrating a new understanding of the subtle microphase dynamics that are key for the function of this recyclable LCE. They also demonstrated different ways of crosslinking BPC films as well as cholesteric hydrogels with mechanochromic responsive color.
• WP 2–3: The Luxembourg team showed their recent success in upscaling the spinning of cylindrical CLCE fibers with mechanochromic response into a fully continuous process, allowing fibers of arbitrary length. They also showed recent results from their collaboration with a fashion designer in knitting mechanochromic garments using the fibers.
• WP 2–3: The Luxembourg team also showed a proof of concept of flow-processing LCE precursors for patterning topological defects into the director field. They demonstrated a 10 cm diameter and ~1 mm thick circular LCE with four tangential +1 defects which delivers cm-scale actuation upon heating. This work also garnered the best poster prize at the GLCC where it was showcased for the first time to a broader audience.

At the meeting we had the pleasure to host two specially invited guests and collaborators of the ALCEMIST project, Prof. Apala Majumdar from University of Manchester, UK, and Med. Dr. Attila Dubecz from the Heliosklinikum Erfurt, Germany. Apala is an applied mathematician who is supporting ALCEMIST with developing analytical models for analyzing complex flow behavior in liquid crystal elastomer precursors, and Attila is a surgeon specializing in robotic surgery, together with whom we are developing our mechanochromic CLCE fibers to be used as suture threads in order to give robotic surgeons feedback on tension during suturing. The presentations by Apala and Attila and the discussions with them throughout the day were truly enriching for the meeting and for the whole ALCEMIST team.




The workshop was wrapped up with a dinner for all participants during which the lively discussions continued.

On 13th of June we had a small kick-off meeting for ALCEMIST, although we were still in the process of recruiting the last team members. We had the pleasure of having innovative textile artist Chloe Bensahel visiting us, sharing some of her beautiful work with responsive textiles, responding to touch with sound, light and color changes. Truly inspiring for the ALCEMIST team as we are developing textile fibers that inherently change color or shape upon the right stimuli. We will continue working together as the ALCEMIST materials get more mature.
