This week we had special visitors in our labs @chemistry-tuw.bsky.social! 22 kids came to participate in our "Materials for 3D printing" Kids' Uni workshop to understand what happens inside a 3D printer and how we can influence the outcome as chemists.

Input determines output-a fundamental principle in science. Of course this remains valid in times of AI ->Responsible Open Research practices are more relevant than ever! Let's contribute to meaningful input by taking transparency, due diligence and metadata seriously! www.nature.com/articles/d41...

Researchers who use hallucinated references to face arXiv ban

The preprint server is the latest to impose stiff penalties on authors who contribute to AI ‘slop’ — but not everyone is convinced it’s the right approach.

Crystallinity uncommon for polymer networks - especially when they are densly crosslinked and not elastomeric. Check out how we can literally "trap" the liquid crystallinity of liquid formulations in photocrosslinked networks. Fantastic work from Michael Göschl: www.sciencedirect.com/science/arti...

Trapping crystallinity in highly crosslinked thermosets by light-based 3D printing from the liquid crystalline phase

We propel photopolymerizable liquid crystalline (LC) shape memory materials from solely elastomeric performance to the thermomechanical performance of…
