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...

Did you know that trioxanes are acidically degradable? We have used this motif for the first time in polymers to make and break 3D printable photopolymer networks on demand with light. Check out the early version here, published #openacess thanks to TU Wien Bibliothek: pubs.rsc.org/en/content/a...

Have you been wanting to #3Dprint materials with late gel-points but were too impatient with the long printing times? Our dual-cure printing technique recently published in #MaterialsHorizons may be the answer: doi.org/10.1039/D4MH... Phenomenal work by PhD student Florian Mayer! #MatSky #ChemSky
Sequential curing of first a radical network during 3D printing and second a cationic network during post-curing into an interpenetrating network.

Interesting study commissioned by Austrian basic research funding agency @fwf-at.bsky.social Fundamental research pays off for society and economy SHORT term-In German but I bet AI can translate it for you I'm curious: Did other countries' funding agencies ask similar questions/find similar answers?
