Correction. 2.5%. Regular atmosphere was not far away anymore.

Even flushing the freezer with argon. O2 only spiked to 13000 ppm 🤪 (the screen shortly also switched to percentage...).

The final work to become operational. The repaired freezer of our glovebox arrived. Just had to put it in rapidly in the counterflow in the stupid hope that o2 would not spike too high...

Until two weeks ago, I didn't even know this journal existed. And now I already have a publication there ;)
A wonderful collaboration with Manfred Scheer's group on a 13/15 analogue of ethene.

Functional Al/Cd Heterometallics─From Controlled Al(I) Transfer to Nucleophilic Transfer of Cadmium Ions Low-valent cadmium compounds have remained largely unexplored as electron reservoirs, with no precedent for their use in reduction or bond activation chemistry. Here, we address this gap by integratin...

Thrilled to share a first publication of the group! We report on cadmium aluminyls that find application as Cd-nucleophiles and(!) Al(I)-Transfer reagents. Now out in @jacs.acspublications.org ! 🥳👍
Thanks a lot to @chemieverband.bsky.social for the generous funding. pubs.acs.org/doi/10.1021/...

Stepwise and reversible assembly of [2Fe–2S] rhombs to [8Fe–8S] clusters and their topological interconversions - Nature Chemistry Elucidating the nature of the metallocofactors in nitrogenase enzymes, and preparing synthetic analogues of these clusters, is a classic target for bioinorganic chemists. Now the transformation of [Fe...

Over the past years we traversed a huge network of FeS cluster conversions: 2Fe2S-to-4Fe4S-to-8Fe8S… and all the way back again! @natchem.nature.com @ethz.ch www.nature.com/articles/s41...

Promiscuity in Molecular Mimics of the Cysteine Dioxygenase: Effects of Selenium in the Substrate and Cobalt as the Central Metal Ion A biomimetic model for the cysteine dioxygenase (CDO) was found to be also capable of selectively dioxygenating selenocysteamine, suggesting that the lack of reactivity found for the CDO in combinati....

Gratulation Dinah.🎉 Ich kann die Erleichterung bis in den Osten spüren (und nachvollziehen).

JOB ALERT! 🚨 Are you interested in organic synthesis and catalysis? We have an open PhD position in our group at Philipps-Universität Marburg in Germany. 👩‍🔬👨‍🔬 Deadline: 10th August 2025. For more details and to submit an application, please refer to the official posting here: lnkd.in/e_f3Xerq

Second that. The same could be said for @rsc.org journals. It is a pain to have a number of different possible social media platforms. But others are more flexible such as @angewandtechemie.bsky.social and other journals from Wiley.

A well timed publication in @chemcomm.rsc.org for transitioning from @unimarburg.bsky.social to @unileipzig.bsky.social. Our view on recent developments in linear metal(I) chemistry in part from our lab in Marburg.
There is still a lot to do on this topic in Leipzig. 😊

Nice work. It is always nice to see the resemblance of both metals (and Zn). Long road to N2 activation with Mn. I still remember Patrick's attempts...

It's getting real and is still unreal. First days @unileipzig.bsky.social, with lots of room to fill (still need to pack our lab stuff in Marburg). I'm a little scared to fully dismantle our large glovebox.

Soft magnetic hysteresis in a dysprosium amide–alkene complex up to 100 kelvin - Nature A dysprosium amide–alkene complex shows soft magnetic hysteresis loops up to 100 kelvin, arising from the high charge density of the amide ligands and the structural role of the pendant alkene.

Delighted to announce the publication of our work in @nature.com, in collaboration with @nfchilton.bsky.social's group, on a dysprosium compound with magnetic memory at 100 Kelvin. Congrats to all authors inc. @gemmagransbury.bsky.social, @jeffjefftyjeff.bsky.social

Congratz and all the best Josh. See you around at conferences 😊

It was a pleasure to host you. A perfect guest for my last acts in @unimarburg.bsky.social before moving to Leipzig 😊. I'll miss already the very funny and lively restaurant visits after every talk, thanks to the colleagues in Marburg.

What don't you do for your kids. Trip to Baku with one of zhem to an international math Olympiad. A nice occasion to visit an interesting country I likely would have never visited. Also my first real trip outside of Europe as I hesitate to do such longrange trips. Now I had a good excuse.
