I would not say that this refinement was unstable, it was rather dancing.

We have Physics Department in the same building, see the proof.

“Radium” candy with cyclopropane images on a package.

This lithium is a friend of this radium.
Yes, this is an actual candy.

Yesterday was a day of small molecules - 3 good structures, today was a day of macromolecules - a polypeptide and beta-cyclodextrin with some stuff inside.*

*Hopefully, otherwise we will have another high-quality dataset for hydrated bCD.

Congratulations!

That part was CLOSED!!! Because it was "cold" and "winter" = +12 °C and sun.

#BraggYourPattern from Granatium museum in Austria, a fragment of the Garnet Room wall.

You were moving to that direction :)

We applied Advanced Crystal Harvesting Instrument aka a longer spoon and determined that it is indeed a sucrose.

Radenthein in Austria.

Yes, I remember that I learned it from you about US and my reaction was “Whaaaat?”

A big model of red rhombic dodecahedron attached to a cliff near Granatium museum.

If your city does not have a huge red rhombic dodecahedron, I am not coming.

Proline from initial post- checked, stupid disorder every time.
Citrate - checked, can you just decide about your protonation state?
Shitty anion aka Tf₂N⁻ - checked, can you be disordered just over two positions and not more?

Here I agree.

A fragment of molecular structure containing disordered proline.

This is easy - that stupid ring that is too often disordered.

We (wife and me) hate it so much that we found a new polymorph of proline. And we didn't even wanted it.

A glass jar 🫙 labeled “crystallized 🍋 ”

I am pretty sure that these lemons are not crystallized - no long-range order.

Summer is here, so back to biking. Take this, traffic jams.

Easier to point out who would not be triggered :) That is clearly US classification.

A food supplement label, claiming that it contain magnesium metal.

Li - not yet, but a food supplement with Mg you can buy in US. Not Mg something, just Mg metal in a food supplement (according to the label).

*from my carefully curated collection of WTF labels.

A form from Elsevier: What are your ethnic origins or ancestry? Select all geographic areas from which your ancestors first originated. Western Europe (e.g., Greece, Sweden, United Kingdom) Eastern Europe (e.g., Hungary, Poland, Russia) North Africa (e.g., Egypt, Morocco, Sudan) Sub-Saharan Africa (e.g., Kenya, Nigeria, South Africa) West Asia / Middle East (e.g., Iran, Israel, Saudi Arabia) South and Southeast Asia (e.g., India, Indonesia, Singapore) East and Central Asia (e.g., China, Japan, Uzbekistan) Pacific / Oceania (e.g., Australia, Fiji, Papua New Guinea) North America (Canada, United States) Central America and Caribbean (e.g., Jamaica, Mexico, Panama) South America (e.g., Brazil, Chile, Colombia) Self describe I prefer not to disclose

Elsevier: let the fight begins!

I have some questions about this form and even more about the next one, with a race question.

Times are not so desperate…

Hear hear, IUCr2029 @iucr2029.bsky.social is here!

A positive sign from the organizers of a very much awaited #crystallography congress that is getting closer and closer 🔥

Give it a nice 'Follow', fellow structural chemists 🤜✨🤛

Thanks! It corresponds to 15 year old, isn’t it?

Thanks! I was checking US Amazon for some food supplements and most brands are ether failing this task, ether not giving enough info to judge. A similarity with bad students is the fact that there are few wrong values, obviously copy-pasted wrong few sources. I can see clusters :)

I have a question to US/education part of #chemsky -
at what age students should be able to solve a problem like this:
“Calculate mass fractions of magnesium in magnesium carbonate” ?

A cover of Between Two Rivers book.

Bluesky is the most expensive app on my phone, and the reason for that is books that I found here. Special blame on @heydebigale.bsky.social , @moudhy.bsky.social and other.

Don't let "hidden" data go to waste.💎

Not every crystal structure ends up in a formal paper—but every structure has value.

CSD Communications gives you a direct route to share small molecule structures in the CSD without the need for a full scientific publication.
