Vielleicht geht's mit Voxel vom 3D Drucker besser 😉

Forschungsdaten – we care to make it FAIR! Offene, gut dokumentierte Daten sind ein zentraler Baustein moderner Forschung. Die FAIR-Prinzipien – findable, accessible, interoperable, reusable – stellen sicher, dass Forschungsdaten auffindbar, z...

What research practices are truly open and FAIR?
Thanks Livia Beck and Christiane Stork (Technische Universität Wien Center for Research Data Management) for the interview and sincere interest in the researchers' experience!

Warum der 3D-Drucker der Zukunft nichts für Wuerschtl ist - SBP114 In Ausgabe 114 des Science Busters Podcasts spricht Martin Puntigam mit Katharina Ehrmann, Chemikerin für angewandte Synthese-Chemie an der TU-Wien, und Peter Weinberger, Prof. für anorganische Chemie...

Ich bin schon lange #ScienceBusters Fan - dass ich nun Gast bei Martin Puntigam und Peter Weinberger im Podcast war, ist eines meiner persönliches Highlights dieses Jahr!

Thanks @dryeeseeks.bsky.social !

🧩A TU Wien team led by @k-ehrmann.bsky.social developed 3D-printed materials that change their properties with temperature – even revealing hidden QR codes.

Trioxanes as photodegradable motifs for additive manufacturing We introduce trioxanes as a new motif for on-demand photolysis of 3D printed polymer networks via an orthogonal light source using photoacid generators (PAGs). The acid-induced degradation of otherwis...

#FAIR: Curious about the first version prior to peer review or raw data? 🔎 We have uploaded a preprint to @chemrxiv.bsky.social (chemrxiv.org/engage/chemr...) and our processable data to #TUWienResearchData (researchdata.tuwien.ac.at/records/qjcp...) 🤓

Work led by Florian Mayer and supported by Dominik Laa at @chemistry-tuw.bsky.social @tuwien.at

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:

Great reflection - and only two-bite-sized 😉

Congrats to Selina for the best presentation award at BYPoS - a well-deserved recognition for all your hard work in the lab during your Diploma thesis on new star-shaped monomers for 3D printing!

I've enjoyed every discussion in and beyond this project with you!

I typically don't use 'finally' talking about research results - it takes as long as it takes - but this study is the joint effort of brillant @Xingyu94010651's and my postdoc time with @BarnerKowollik in AUS. I thank her and the entire team* for the exceptional collaboration!

Two Material Properties from One Wavelength‐Orthogonal Photoresin Enabled by a Monochromatic Laser Integrated Stereolithographic Apparatus (Mono LISA) A single object with dual properties – degradable and non-degradable – is fabricated in a single print simply by switching the printing colors. The advanced multi-material printing is enabled by the ...

It's FINALLY out! We introduce MonoLISA, a new 3D printer using monochromatic light between 210 and 2400 nm, and a first photoresin to print degradable and non-degradable materials with two colours of light!

Haha - I take it you know them? 😀

Time to focus and reflect on teaching methods today - including my favourite Austrian snack!! 😍

Reading recommendation of @polykonkol.bsky.social and @polymerreaction.bsky.social's latest work: Temperature matters in photopolymerization! Thanks for spreading the word and giving this message a stage 👍

Here's my first go at bringing together everyone who does polymers + 3D printing!

Polymer chemistry, rheology, characterization, devices, etc. All are welcome!

Let me know if you want to be added to it
