It was nice to meet some familiar and new faces in Chemiedozententagung 2026. @ettlab.bsky.social @knebelalexander.bsky.social

Kick-Off of our new project "RespoBrane", with the groups Schacher (Uni Jena), Wyrwa (Fraunhofer IKTS), Bliedtner (EAH Jena). << 3D Mixed Matrix Membranes with Stimuli Response for Innovative Separation Processes >>.

Trendbericht Festkörperchemie und Materialforschung 2026 Wie wichtig Festkörperchemie und Materialforschung sind, unterstrich der Chemienobelpreis 2025, den Susumu Kitagawa, Richard Robson und Omar Yaghi für die Entwicklung metallorganischer Gerüstverbindu...

Double feature in @gdch.de Trend Reports. Two of our collaborations are featured: Multi-level anti-counterfeiting NanoMOFs with Klaus Müller-Buschbaum @jlugiessen.bsky.social , and the CO2-capturing Phosphonate MOFs from Gündog Yücesan and with @hhu.de onlinelibrary.wiley.com/doi/epdf/10....

The algorythm and interface of Bluesky makes it incredibly hard to see relevant posts from peers or anything relevant at all.

Ångstrom Scale Pore Engineering in ZIF-62 Glasses by in vacuo Heating-Induced Amorphization Zeolitic Imidazolate Framework (ZIFs) glasses possess both the intrinsic porosity of Metal–Organic Frameworks (MOFs) and the melt-processability of conventional glasses, thereby representing a new cla...

Great and new collaborative work with Michael and Jiamin at @univie.ac.at on the control of porosity on the Angström-scale in MOF-glasses in vacuum. Check out the pre-print: chemrxiv.org/engage/chemr...

The IZMM 2026 announcement is finally out! We are welcoming you to join us in Jena in June 2026. Check out the website, register and send us your abstracts. More infos on the speaker line-ups and so on will follow soon. Stay tuned!

Resolving Dye Embedment in MOF‐5: Multimodal Evidence for Perylene‐Based Guest Encapsulation Unambiguous discrimination between surface-adsorbed and pore-incorporated photoactive dyes remains a key challenge in hybrid MOF systems. This study presents a comprehensive multi-technique approach ....

Very happy that we from @uni-jena.de could contributed to this great collaborative paper lead by Fabian and Heidi @uniinnsbruck.bsky.social, as well as @markussuta.bsky.social. We investigated multimodal encapsulation of pyrelenes as guests into MOFs. advanced.onlinelibrary.wiley.com/doi/full/10....

Nobel Prize in Chemistry 2025 The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal–organic frameworks.”

Our paper on the precise control of pore channels in ZIF-62-glasses made it into the Nobel Prize Collection of @nature.com This makes me enormously proud! Thanks to everyone involved!

Heartfelt congratulations to Omar Yaghi, Susumu Kitagawa and Richard Robeson for the Nobel Prize in Chemistry 2025. Well deserved and long overdue!

Just back from a great 2 day symposium between the DFG research training groups PhInt (Uni Jena) and SPECTRE (Uni Rostock). Both RTGs deal with light-matter interactions. We had a nice time, educational trips and strong scientific exchange. Svetlana, PhD student in my group, delivered a talk. 🌅

Setup is back online. Took half a year to repair... mainly because of delivery. Not beautiful but it works and it got some upgrades. Also, it now has LEDs that blink in RGB colors 😄

Spread the word and save the date! June 22.-26. 2026, the 10th International Zeolite Membrane Meeting, welcomes you in the beautiful city of Jena, Germany. Organized by Hannes Richter, Ingolf Voigt @fraunhofer.bsky.social and myself from @uni-jena.de

A great opportunity to give a talk at the #ECerS in Dresden. "Molten MOF Membranes - ZIF-Glasses for Highly Precise Molecular Sieving". Thanks to my group members for fueling the talk with content, and to Prof. I. Voigt from Fraunhofer IKTS for inviting me.

Call for papers on MOFs, COFs, Zeolites until March 2026: “Advances in Reticular Microporous and Mesoporous Materials: Design, Characterization, Properties, and Applications" (VSI: ARMMM) in Microporous and Mesoporous Materials (IF 4.7). @elsevierconnect.bsky.social

I am very worried about climate change as well, and my research is based around that. However, don't you think your x and y axis scaling is immensely exaggerating? What a bunch of non-scientific panic plots ... the world is not lost, yet. Researchers working hard on a solution. Keep your head up!

Stable Ultramicroporous Metal–Organic Framework with Hydrophilic and Hydrophobic Domains for Selective Gas Adsorption The ultramicroporous pores of TUB41 selectively host water and CO2 molecules at distinct hydrophilic and hydrophobic compartments without competition.

Our study is out in @angewandtechemie.bsky.social. We demonstrate CO2-capture in a Cu-phosphonate MOF over the course of 2 years. In Jena, we did the in-situ T-dependent XRD and were amazed by the material. A fruitful collaboration led by R. Oestreich and G. Yücesan doi.org/10.1002/anie...

All 4 of our manuscripts are currently in review, some for longer but with a very delayed response. I hope they don't all come back at the same time. Quadrupple revision will kill me.

Being internationally visible can backfire when publishing with @natureportfolio.nature.com nowadays — editors started inviting 7–10 referees at once. You may face 5–6 reviews. Too many cooks spoil the broth; 3 referees is good, more referees lower the quality of peer review in my opinion.

Polycrystalline membranes from the "dense" MOF MIL-116(Ga) demonstrate exceptional performance in helium upgrading from natural gas. We thoroughly investigate the influence of crystal growth and grain boundaries on gas permeation. Read our pre-print on reseach square doi.org/10.21203/rs....

Three papers simultaneously submitted. One recently accepted. Only one in the making. Feels good to finally get things done again! Papers blocking the desk feels so bad. Hopefully, referees will be nice.

If you ever get pressured to finish up a 5 year old paper with 25 co-authors on it, I can give you one advice: Say no and pretend to be dead. The more internal revision rounds you do the stronger your depression peak. They will answer-all emails with "major concerns" about their own piece of work...

I know exactly what you mean. The next the time you include more preliminary results and they will tell you that you don't need funding, because you will make it without money.

Well, this is probably an ethical discussion with many facetts. But the way Springer Nature does it, if you want your name being published then its done, sounds good to me.

Problem with ACS is that these editors are busy Profs somewhere on this planet, and not full-time editors. I am guest editing for a journal myself... there are guidelines. If they follow these guidelines its a great experience for everyone. This however, feels MDPI-like here, pushing papers through.

Follow-up to my reviewer experience with ACS Langmuir.

Invitation recieved on 08.07.2025, 4 a.m. CET.
Accepted on 10.07.2025 ~8 p.m. CET.
Reminder "Review due" recieved 12.07.2025 (Sa) 2 a.m.
Notification "Review no longer needed" 14.07.2025 (Mo) 9 a.m.

Will not review in the future.

Accepted to review a paper on Thursday. First reminder "your review is due soon" on Saturday, 2 a.m.

Calm down Langmuir, calm down.

The #MOF Universe got a massive update with many additional information. We asked also for potential collaboration intentions - so have a look!

Many thanks to everyone who took part in the survey and to the COST Initiative EU4MOFs for funding my work!

Would be cool if we could realize this biological aspect in our technical realization of membranes. Membrane technology is still suffering from a strong technical abstraction. Self-repair and stimuli-response is the way to go!
