@b-kajetan.bsky.social is making holes in a carbene - deformation density map from NoSpherA2 with Cu data.
But you forgot ago MS politics "We don't care what is your settings". AFAIK, one need to go deeper to system setup to fix it, I did it for my home PC long time ago.
Pardon my French, but this really WTF moment. I was kinda working, you know and I didn’t ask for any updates.

Hey, @ccdc.cam.ac.uk, when is the cut off date for #CSDWrapped statistics with year? End of October?

Yeah, this is a really high level of academic rickrolling.
Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com
Have you ever heard about the most famous suitcase master? Ah, he also created periodic table.
Beer example is good, I am 90% convinced now. Is it the same for a diffractometer? Single-crystal or single crystal?
Btw, should it be “single-crystal diffraction”? Because for me “single-crystal” is an adjective in this case.
A "can you show me a full reaction?" structure again, from my usual supplier @dr-berionni.bsky.social group.

*Looking on the news* This a a promising linker for new class of perspective MOFs. (Not really, just a starting material for different stuff).

(1/x) Some thoughts on a recent case: I raised concerns about an article published in 2010 w/ Wiley's IACR team in August 2025. I considered the problems to be severe and clearly indicative of manipulated data (see image below): Sarhan et al. 2010 (DOI: 10.1002/app.32522) pubpeer.com/publications...
One step on a time :) But yes.
I kinda promised to @louisedawe.bsky.social to submit in the JACS (Journal of Applied CryStallography) :)
I may give different promises, but to write a book - oh, no-no-no :)
*foil hat on* The only reason today's Nobel prize was given to #MOFs, is to revive #ChemSky aka #ChemTwitter - just look on your feed now.
Most credits go to Escher :) But making proper cookies cutter also took me few iterations.
I don’t remember if it South or North Italian corner, snacks may vary… Our department is clearly South :)
I hope to finish the rest of wallpaper groups cookies during this New Year holidays :)

Okay, today is physics #NobelPrize day, so there's just enough time for another instalment of...

PHYSICS NOBEL PRIZES YOU’VE NEVER HEARD OF – PART 2

In 1912, a Swedish inventor called Gustaf Dalén beat Albert Einstein and Max Planck (inter alia) to the biggest prize in physics. How? Well...🧵🧪⚛️
You said this and after recalling the building layout I realized that it is indeed the Italian corner!
This is the place of my past chemistry (mostly) crimes :)
Speaking about working conditions - here is the photo of my previous place (I was passing by yesterday).

And yes, I have no idea what is going on :)
Somehow I ended up inside a NMR console this afternoon with realization that I am touching NMR only when it is not working.
