Let's go for a perspective review on NatureEdibleMaterials

Stefano Canossa @stecanossa.bsky.social · 5h

Well, well... who wants to be cited at the beginning of one of my papers next year? #NobelPrize

The first three references in my tutorial review, respectively citing the foundational works by Robson, Kitagawa, and Yaghi in the field of MOFs.

"Kitagawa told reporters (...) that he pursued this research because of its potential impact on society, but also because of the sheer fun of it."

If you look inside so many great scientists you will consistently find that deep down they did it for the fun and beauty of it all.

Ahah awesome 😂

I guess it's time to dust off a celebratory picture of my memorable visit to Omar's lab a few years back, with my good friend Stefan Wuttke 😊 #MOFs

A picture of me with Prof. Omar Yaghi and Stefan Wuttke, in Omar's office.

and MOFs it is!!! #Nobelprize

accurate version should be "taralli toroidali"

Stefano Canossa @stecanossa.bsky.social · 19h

They're so awesome, and the googly eyes are truly the 'chef's kiss' 😄

This is a great idea. 💯

"Taralli are toroidal" is my current favourite fact as far as phonaestetics goes.

#topology

A Wikipedia entry about the typical italian snack "Taralli" starts with the sentence "Taralli are toroidal italian snack foods, (...)"

Conclusive validation would be checking nearby and finding small bowls for Taralli, and the typical teardrop-shaped "grana knife": someone had an aperitivo there ✔️

Thanks! I'd love to hear which is your favourite section, or like a top 3

Stefano Canossa @stecanossa.bsky.social · 2d

I'm so happy to see Prof Choe @chem571.bsky.social appearing here, welcome Wonyoung! Bluesky really needed the beauty of your #MOFs science 🌟

#NobelPrize week starts tomorrow & the #chemnobel is Wednesday… used to be so much Nobel chat on Tw*tter, but that is not replicated here, alas. Anyway, for the record, I think MOFs will win at some point (maybe this year maybe not). Balasubramanian & Klenerman a good bet for next-gen sequencing too

Maybe some Italian brought some salame and that is to keep it still while slicing it...

Oh yes I cited that, very rich one!

Stefano Canossa @stecanossa.bsky.social · 4d

Thanks, my friend 🙏🏻 I really hope that many will give it a chance!

My tutorial review on single crystal diffraction analysis is now online @crystengcomm.rsc.org! Students, supervisors, and reviewers: Please consider this thought-provoking read to discover many facets of the crystallographic practice that are often overlooked or misunderstood 💎 #crystallography

Useful practices in single crystal diffraction analysis of reticular structures

Single crystal diffraction analysis remains the gold standard for the three-dimensional atomic structure characterization of framework materials such as metal–organic frameworks, covalent organic fram...

(... and someone else in Verona asked themselves why a guy is trying to find a good angle to take a picture of what looks like just a manhole cover.)

Stefano Canossa @stecanossa.bsky.social · 6d

Someone in Verona decided to make "phonon-ish manhole covers" - Approved 👌🏻 #Braggyourpattern

A manhole cover, where dots on a square grid are smoothly deviating from the square lattice, resembling a phonon in a crystal.

When diffraction data has low resolution you can always make some Rorschach Tests out of it. #crystallography #Braggyourpattern

A difference Fourier map shows red blobs surrounded by green-red-green etc. ripples, in an overall triangular symmetric pattern.

Time to stir controversies... but I had this meme in mind for too long

$A famous meme shows two office mates arguing with animosity over contrasting opinions. In this case, this is how the conversation went: A: "today a student said 'xrd spectrum', I made it quite clear they're wrong" - B: "Well not in energy, but it is a spectrum: of spatial frequencies" - A: "Diffraction is elastic, calling it spectrum makes confusion!" - B: "Then don't say 'Bragg reflection', it is not a reflection!" - B: "And actually diffraction is seemingly elastic, but fundamentally FULLY inelastic!"$

What about you come up with a nice pattern idea, I make one for you, and you print it? Customized FFT! It's not a business yet, so you can take the chance for free 😏
