New UV/Vis from Ocean Optics arrived today. It really lives up to the compact product name. Oo Will ultimately be setup for in-line flow measurements for adsorption and continous flow synthesis. 💣

I think we should normalize a 10-year productivity drop after becoming a parent. I barely keep my head above water and it's all thanks to my fantastic partner who does most of the heavy lifting.

Indole.

This even managed to trickle down to Danish newspapers announcing it as a big new water harvesting appaeatus...

Whya are IDEX fittings etc so expensive? I know it's PEEK but still. Buying regular stuff, some connectors, a check valve and then BOOM 10K EUR.... :,(

Yes. I would love some chem-themed art! Our dept. is in a new building, and it is overall very artless. :(

I got a new office. Quite big. What should I get? Bean bag? Large banana plant? Pinball machine? Something else? And how do I justify it on my uni. card?

I have not been active on Bluesky for quite some time, but I think it's time to come back. Hopefully the #chemsky community still is alive and kicking. :)

This summer, the 46th ICCC will take place in Denmark. As part of the conf., @carolhua.bsky.social and I are org. a symposium on chemical sensing using inorg. and hybrid materials (inc. MOFs). We would be happy to see contrib. from researchers at all stages of their careers.

Please share!

ICCC is coming to Denmark. The lineup looks great already. And I've heard rumours there will be a symposia on chemical sensing using hybrid materials, anyone who comes (to the symposia) will get a free tour at the sausage museum at Den Smagløse! #iccc2026

Useful practices in single crystal diffraction analysis of reticular structures Single crystal diffraction analysis remains the gold standard for the three-dimensional atomic structure characterization of framework materials such as metal–organic frameworks, covalent organic fram...

My tutorial review on single crystal diffraction analysis is now online @crystengcomm.rsc.org! Students, supervisors, and reviewers: Please consider this thought-provoking read to discover many facets of the crystallographic practice that are often overlooked or misunderstood 💎 #crystallography

PD Alert! 📢 We're hiring a 2-yr fully funded postdoc in automated MOF synthesis at DTU in Copenhagen! 🇩🇰

You'll help build our new lab and join a fun, collaborative team of chemists, engineers & physicists. #chemsky

Dear #MOF #COF community, please consider interacting with the posters you see under the hashtag #MOFSchool2025 🙏🏻 These scholars are looking forward to connecting and discussing with you and you can make an important difference for their experience as remote attendees! #PorMatSky

Due to some unforeseen consequences, we have an immediate opening for a 2-year PD position on the automation of MOF thin-film synthesis at Technical University of Denmark. There will be an official opening soon, but anyone who is interested an reach out to me directly already now. #chemsky

Didn't know this, but might explain why our uni doesn't provide a site license anymore.... I switched to MarvinSketch.

Sadly, Journal accounts have flooded #chemsky, likely causing the noticeable drop in human posts. Please try consciously to keep this place alive by muting all the paper bots and re-engage with the scientist's posts here. It would be a pity if chemsky was lost.

Our group currently collaborates over Teams, which is ok but not great. Are there any, prefferably open source, alternatives? We need chat, files sharing (>200 gb), notes (OneNote similar). Possibility to co-write/collaborate on docs would be great (which Teams suck for when someone is on Linux...)

My (uneducated) guess is that demand for people who know how to write will skyrocket. My students are still OK, but its getting worse and in five years we will have people who can't formulate a sentence. Yet, communication is top 10 skills companies want.

Trump did a horrible first term, but I'm honestly surprised how much damage he has managed to do in such a short time this time a round. Not looking positive for the next 4 yrs. :(

At least I'm to poor to get a Porsche.

A movie about ghost pets discussing human philosophy actually sounds good.

Large-scale synthesis of explosive compounds?

Reactions in acetone at 60 °C higher than the boiling temperature of acetone?

Reflux at temperatures lower than the boiling point of the solvent?

This paper has it all!

Check out the new preprint by @arbitraryeffect.bsky.social and myself!

Although I feel for Americans academics, there are scientists in other countries who are much worse off and has been for a long time. But we never see initiatives to help them get established in the EU....

compressed gas tank with a ⊞ on it (defaced swastika)

common knowledge among chemists:

compressed gas cylinders basically last forever. some date back to WW2. those used in Nazi Germany (Linde) were marked with swastikas.

after the war, the swastikas were defaced into "windowpanes" ⊞ — you can still find such cylinders in the wild today.

I once ordered a vegan patty but got a lobster instead. My neighbour was very happy tho.

Maybe it's obmnly via file export and not copy as?

Thats odd. Mine can, and the manual also states that svg is supported: docs.chemaxon.com/display/docs...
