Polish lunch 🥰

This diffraction pattern is from one of the most exciting structures I got so far. Collected with 'naked' beam at synchrotron, poor res, but solves. The problem is that some atoms in the side-chain are 'missing' and can't really be located with this data quality and possibly a disorder... 😭😭😭

Super happy that I could contribute to this excellent paper! The holy grail of oligo-porphyrin chemistry was finally made 😍

Goodbye, Diamond! See you remotely next time! 💎

The gods of crystallography have been relatively good for us today 💎

First-ever preparation of shipping of crystals to @diamondlightsource.bsky.social in our group @besserchemistry.bsky.social is finished! We’ll find out how good my technique was in about two weeks 😄

Successful collection of a dataset at DESY. Now have one macrocycle crystallised as three different solvatomorphs with different packing!

Feels so nice when you get a paper to review, you suggest some revisions and then authors introduce them and it all looks so much better! #HappyReviewer P.S. Also decided to reveal my identity in the report in the end. I think it’s fair.

Checking whether anyone did an experiment I need while writing a paper and finally found it. Reference to a spectrum I was searching for: „Author X, Author Y, PRIVATE COMMUNICATION”. 😅😅😅 How was it even allowed?!

It’s my new crystal baby😊

Weekend in Albania 🇦🇱

Struggling with a terrible twin refinement. Everything looks OK during processing and when adding data from second component to the refinement it just doesn’t change almost anything in the R values… 😓 And the dataset is quite good, with nicely separated reflections! #crystallography

Picked a big boy today. Not bad for something with molecular mass of 2500 😌

7h HSQC on a compound that gives signals with height half of the solvent’s 13C satellites and it looks good! 😌

… and here the Team Ulm @uniulm.bsky.social risking their own (dry) lifes at #ISMSC2025

My research during the 1st year of PhD:

Someone decided to do a theoretical study on our [18]annulene sandwiches! www.sciencedirect.com/science/arti...

Okay that’s one nice looking column! I wonder what is the violet thingie 👀

Fingers crossed for Justyna Steczkowska! I wasn't really following Eurovision in the previous years but they finally chose someone who can actually sing! 🇵🇱 #Eurovision2025

It's a routinely generated thing but feels nice anyway. Btw i really enjoy peer-reviewing manuscripts so you know, Editors 👀

That crystal looks rather hot 🥵

Cute little goosie

A small adventure by the Baltic Sea in Poland, I even managed to find a relatively rare jellyfish (cyanea capillata)! 🪼

Congratulations to Wojciech Stawski from Ulm University for winning the CCDC/CCG Prize 2025, announced this afternoon at the @crystallography.org.uk Spring Meeting. Discover more about Wojciech Stawski's ground-breaking work here: ccdc-info.com/4imVWF3 #Crystallography #BCA25

Extremely happy to have been awarded a CCDC Young Crystallographer Prize @crystallography.org.uk @ccdc.cam.ac.uk Again, a big thank you to all who made it possible, particularly those shown in the slide.

Awww thank you for sharing!

@stawskiwojtek.bsky.social , it seems that pain with structures pays off :) Congratulations!

I think I have a CRAZY DISORDER with THF hiding under this already disordered hexane 🥲 #crystallography Look,@ntumanovxray.bsky.social !

Have some good news for @mvdelius.bsky.social 👀

The crystal I grew is shining in the X-ray beam! #crystallography Here you can see what happens when the beam is on and then switched off! @besserchemistry.bsky.social

-This NMR looks clean -[In the meantime, the SEC column:]

Ahoj!

My first attempt to cheesecake(s) with German cheese. Fingers crossed 🤞

Nothing more refreshing than spilling 100mL of glacial acetic acid under fume hood 🤮

The fact that I baked a Maria Skłodowska-Curie themed cake (polonium and radium) on the day the results were announced can mean only one thing 👀🎉

Great fully funded opportunity for some undergrad students! If you know some that fulfill the criteria, tell them! 👀

Good old-school crystallization by sublimation under vacuum in a flame-sealed tube 😇

Christmas is early this year. #crystallography

Feeling cute. Might delete later.

Cute little electrodes

Baked stuff

These little babies change color quickly (from colorless) after removal from glovebox. Patterns are streaky at some orientations (had to cut them which didn’t make them good) so please join my prayers for successful solving 😅

I might have just got a crystallographic heart attack. A structure from Angewandte☠️

Very happy to hear that my application for Walter Benjamin Position from @dfgpublic.bsky.social was successful! 💶💶💶

🎄🎄🎄

A new video in my X-ray series - how to grow good crystals? I show some metods that work well (in my personal experience) and comment on them, as well as how to handle air-sensitive samples. Share with your research group! 😇 #crystallography #chemsky youtu.be/__FQUIutJ2w?...

Making my first battery 🥹

Just finished our first Esser group’s visit at DESY synchrotron. We are going back to Ulm with some exciting structures, great memories and new experience! Special thanks to Leila, the beamline scientist, for great cooperation and fun! We all learned a lot from each other!
