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 :)

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.

Here's my version of the bracket with my hand-drawn minerals.

final Mineral Cup 2025 bracket with kyanite as champion. all the minerals are illustrated and the brackets are lined with decorative border in gold.

Oui :)

I think that this year I brought 10-30 people to #MinCup25 with this whiteboard.
Also my typos accidentally produced a cute mineral name - tugtupetite.

I am not using it right now, it may work in many cases and may not work in many other cases. For example, in crystals with plastic deformation.

Nikolay Tumanov @ntumanovxray.bsky.social · 7d

It is original :)

"Yes, we can bring this 1.86*1.86 m Al plate by elevator, I remember dimensions of elevator. And please do not eat delivery guy, not his fault that it is in one piece."

"Nope, we cannot bring 4 meter toolbox case upstairs, but I know a (only) place where we can store it"
