Asked my 5yo if he was building a forest next to his train tracks with my #iteachchem models in my office at @hhu.de To which he replied rather irritated: No mom, this is an atom exhibition! 🥹

New record of train problems for me. I officially have the worst @bahn.de Karma

A screen shot form the German train app, final destination is Düsseldorf with 1,5h delay. Multiple reasons/issues for the delay are given: late due to delay from before, technical difficulties with train, incidence with needed police, train operation without segment 8 and missing Barriere free toilet. Also exceptionally high demand is communicated.

Today Rachel, who joined the lab 6 years ago during her master studies, defended her PhD thesis in bioinorganic #chemsky @lmumuenchen.bsky.social Glad to also have her as part of the team at @hhu.de @chemiehhu.bsky.social

Two group pictures, taken 6 years apart. Some persons are found on both fotos. In the middle there is a greenish copper statue, in the back a glass front of a Building. The person in the middle makes a goofy face and gesture, on the new picture below one of the persons is wearing a traditional German PhD hat with pictures and decorations on it.

Hey #ChemSky in case you get bored over the holidays, can you spot all the errors on our #periodictable in the big chemistry lecture hall @hhu.bsky.social? To its defense, it is from the 70s 😅 🥽

A large periodic table is shown hanging in a lecture hall. Below is a Fume hood, fire extinguisher, and glimpses of the wooden wall behind and below can be seen as well as a part of a chalkboard. The periodic table is not correct (in addition to missing some elements). All the mistakes will be revealed in a reply to this post

Hey #ChemSky! Anyone know what this is used for? Found this and other glassware during lab cleanup today. Looks like a #Chemistree ? 🌲🎄

Thats rad! Philippes first first author preprint is out: Lanthanide-dependent Methanotroph Thrives on Radioactive #Promethium #fblockrocks! doi.org/10.26434/che... We show that both the Ln-dependent enzyme MDH as well as strain SolV can use the beta-emitter Pm-147 in its metabolism. #chemsky 🧪

Bioinorganic #ChemSky practical course @hhu.bsky.social finished! The remains of our experiments with #siderophores look like Christmas tree ornaments! The blue color arises from the CAS dye with Iron. On some agar plates Bacteria grow that produce ligands to steal iron, inducing the color change 🥽

Finally, we use ion mobility spectrometry-mass spectrometry to investigate the RPB B and MLL complexation in the gas phase with Fe3+ and #lanthanides. Our results challenge the classical siderophore-like Ln-uptake (via simple solubilisation) through MLL

The two chelators are drawn as comics as crabs binding to Fe or Ln ions. Those with MLL sink to the bottom as the complexes precipitate.

@sophieguti.bsky.social found that unexpectedly, both #metallophores precipitate Lns under biologically relevant conditions. We used a combination of single-cell (sc)ICP-MS and LC-MS analysis of bacterial supernatant to investigate the Nd accumulation and MLL secretion under differnet conditions

Here we further characterize methylolanthanin (MLL), a chelator that is involved in Ln metabolism in bacteria (see www.pnas.org/doi/10.1073/...) Yes, methylotrophic bacteria use La, Nd... in their C1 metabolism! #fblockrocks They use them in the active site of methanol dehydrogenase enzymes. Anyway…
