yes, it also suggests that the energy keeping the wood blocks together is pretty similar across the whole piece

It's funny how academic writing led me to normalise words like "intriguing", "to perform" etc., while if I use "intrigante" or "performare" in Italian I feel like I'm straight out of a 15th century Republic of Venice or something like that. #Academia #ChemSky

like: "SEM will tell you crystals are as large as the piece of wood; PXRD will tell you they are as tiny as those small blocks"

A series of cracks in a wooden pillar form parallelepipeds with similar sizes, and an overall fractal structure of cracks and sub-cracks.

Found this pattern on a sun-dried wooden pillar on a hike today - nice educational analogue for the mosaic structure of single crystals isn't it? Such a well behaved cracking #BraggYourPattern

It’s official: the UK is rejoining Erasmus! 👏🇪🇺

Thanks Ivy! Hope you have fun with it! 😊

Woohoo cool, you started big!

Although the tile creation pleasure will lose a bit when going non orthogonal, since input images will always be rectangular and it's not that straightforward to create them nicely for "clinic" systems. Anyways, I would feel bad sticking to squares.

Oh yes, but that's a lot of work and will be a future implementation... no idea how much "future". As I thought, "People are going to ask for hexagons..."

it works kindof surprisingly well for structures like COF-366 (like in the manual), where there is essentially only one plane containing all correlations that run along hk0. What matter are all the interatomic correlations in ab0 planes and parallel. A bit difficult to explain here without pictures

Because the hk0 plane is not containing info on the projection of the structure along l, otherwise I-centered structures would not have extinctions in that plane... it's actually something I have been thinking for a while and tested with Fourier Tiler. In its future publication I'll show that better

(especially since for some COFs you can essentially consider the results of FourierTiler as analogous to those of real diffraction experiments 😏)

Ahahah this, my friend, is a nice compliment 🙇‍♂️

Looking forward to your test results! 😁 Thanks Romain

... and before people get scared by the GitHub page: Fourier Tiler is a completely GUI based, user friendly program anyone can play with, and it does not require any installation 😉

Please have also a look at the manual, where I show examples of educational uses of it.

And of course now anyone can flood Bluesky with their custom patterns... add the tag #FourierTiler so people don't miss any and can find them back! And of coruse, let's saturate #Braggyourpattern as well 😏

Release FourierTiler v1.0 · stecanossa/FourierTiler First release of the program.

I'm so happy to finally disclose Fourier Tiler, the software I always wanted to make, so that anyone can experience #Crystallography and #TotalScattering one mesmerizing image at a time!

Let your creative curiosity run free in real and reciprocal space! #Braggyourpattern

Aaah right

You mean in the article? Oh I wish merohedral twinning was more common than the other ones 😶

Time for a second casual #crystallography tip: peak tables in lattice viewers are not showing you the reciprocal space of the crystal, but just some intensity maxima!
If you think it's a detail, I have a section and a figure explaining why in my recent tutorial review: pubs.rsc.org/en/content/a...

well the shape is not that original considering all the other marbles in the playground, but otherwise yeah

True...

you even have the very fluffy ones that you probably can even make loops from their "needles"

Name: Buldaki - the official mascot of my arrival in Seoul

A yellow small coffee mug hosting a small round cactus with long, healthy spikes.

Following an apparently common attraction of crystallographers for cacti (is it the symmetry? Ancient urge for needles to mount crystals? Low maintenance allowing for synchrotron trips? Don't know...), allow me to introduce my first Korean flatmate - well, spiky mate actually. #crystallography

Crystal structure refinement 10. Routine data processing and solving structure of an imine YouTube video by Wojtek Stawski

New video. This time we look into processing and structure solution & refinement of a non-problematic structure of an imine. Raw data were deposited online so anyone can have a go with it!

Yes, some are shocked by the range of sounds and genres, but I was always carried away by the range of feelings he could explore... Sadly, yet necessarily, due to an awful personal life and condition; it's great to see him happier now. But "City": oh I really did live that album in my younger times

You brought up Meshuggah, I thought "oh, we have have one of us here...". Now Devin Townsend, and I'm "Ah of course, right" 🫶 🙌

Many academics, following sheer numbers and not much else (IMO), ditched Bluesky for "CringedIn"; I assume this is a key discussion topic at @bsky.app. Tools targeting academics (e.g. a jobs section) would be very needed. Please engage with our community and prove that this can be our ideal option

Hi, if you're a student or postdoc, living in the US, going to #IUCr2026, we at the American Union of Crystallography want to give you money.

New deadline: May 1st.
