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...

I always export as SVG and never have font/line issues with Inkscape. PDF with embedded fonts also work, make sure you have all Windows fonts installed for non-embedded files.

Honestly, thinking about how life will look in 7647 sounds quite interesting. Pretty different from today would be my guess.

George Sheldrick will be missed🕯️🕯️🕯️#SHELX #crystallography #education

I'm from Sweden, live in Denmark. One of the things that have impressed me the most is how effective they are at clearing snow, ice etc. You can wake up in a snow storm and bike paths are cleared before breakfast is finished. Most ice-related incidents are probably more alcohol- than actual ice.

Do you have the first of 2nd gen? I see it's in stock now (wasn't last time I checked) and itching a bit to buy one. Just to print composites, so not complex geometries.

I really want a mini SLA to do composites but I ain't gonna pay that much... the other one that was on Kickstarter (with v2 coming soon) was like 150 or so if I remember correctly.

800???

My dream of going to MOF2026 in New Orleans is slowly shattering....

Completely condemn the highly disappointing decision by @acs.org to take down and then amend their pages on Diversity, equity, and inclusion - www.acs.org/about/divers... - this is not what #RealTimeChem stands for.
