While starting to memorize some korean words, I came across "study", 공부 (Gong Bu). I could bet it's related to 功夫 (Gong Fu or Kung Fu) which, as a former Shaolin student and teacher, I know it means "hard work" or "prolonged excercise". It cannot be a coincidence...

This lecture is so awesome, I feel my my mind as materials scientist and crystallographer opening up to quite a few ideas and new ways to look at things... #Chemsky youtu.be/Fx8laV4tH8g

#BraggYourPattern Seoul Edition #2: a... "45° stone wall"? Not quite sure how to call it but I questioned my cartesian reference for a second... Spotted in Namsan Sky Forest trail.

#BraggYourPattern Seoul Edition #1: it must have taken an incredible patience to make this packing masterpiece decorating Sungnyemun Gate 🌺

What if research started by listening? Kristien Hens at the University of Antwerp studies neurodiversity through the voices of autistic people and those with ADHD and Tourette syndrome. #NeurodiversityWeek 👉 bit.ly/3NmFU4S

40' to my one-way flight to Seoul 🛫 🇰🇷 - Overloaded with old memories, new hopes, concerns of integration and solitude, and loads of energy and enthusiasm to make it work and finally find my path 🌱 #academia #IchBinHanna #ScienceMission

Very happy to help shaping this initiative by @sundberg.bsky.social! If you like to support it with your ideas, help, or simply participation as member, please reach out and engage 😊 #neurodivergent #chemsky

Is there any autisttic/ND community established on e.g. Discord? If not, interest in? #chemsky

We're celebrating #InternationalWomensDay by shining the spotlight on one of the most remarkable women of science, who also worked here at the Royal Institution: Kathleen Lonsdale. Watch the short documentary here: youtube.com/watch?v=FNNI0R2gwM4

Sunday March 8th is #InternationalWomensDay Explore Crystal Growth & Design's virtual issue highlighting Women Researchers at the Forefront of Crystal Engineering pubs.acs.org/page/cg...#InternationalWomensDay

... and remember not to cool down your Kilt too quickly, if you don't wanna end up with domain boundaries 🥃 (I might prefer it this way though)

It's been a while since I posted #FourierTransforms, so thought I would risk getting bored with some periodic tilings... until I've found a nice case of #pseudosymmetry in a Tartan pattern 🧐 Can you spot its origin? (pun intended) #crystallography

Oh, I feel a bit "niche" now (peripheral sounds bad)

An article I have been waiting to read for years, by my friend (and #crystallography hero) Juanma Garcia-Ruiz and co-authors, has just been published! "On The Origin of our Fascination with Crystals" 💎 😌 www.frontiersin.org/journals/psy...

#PeerReview is such a strange process. Sometimes I got so excited, but the more I dig the more I find serious problems. Sometimes it all feels bland, but then I recognize that the writing was not delivering well some actually good science. It can take weeks and breaks to really find out. #ChemSky

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 🤜✨🤛

To strengthen my cognitive defenses when I use AI assistants I often add "(...) that's what I have read on the internet" after reading the answer to my prompt. Would be awesome to have Chatbots that remind their training data like this, every once in a while. #AI #SciSky #AcademicSky

New Turing Test just dropped: Bolognese sauce... Maybe we can add it hidden somewhere in university tests? #AI

Today is my last day of physical presence at ETH Zurich, so I thought I would prove to my colleagues that 3n-fold symmetry goes way better with tarts than the mainstream 2- or 4-fold ones! 😋 Did not hear any contrasting opinion during the meeting #SymmetryBaking #crystallography

We're very grateful for support from @oscarsproject.bsky.social helping us build an open database for high quality XRPD and PDF patterns. We've collected a huge amount of data over the last year, which has also contributed to our users' research. We'll be launching the database later this year.

❄️ Don't let your research stay frozen. 4 days left to submit your IUCr2026 abstract, no registration required, just hit submit. This is your final extension. Thaw out that draft and get it in before the window closes. 📅 Feb 22 at 11:59 PM ET 👉 event.fourwaves.com/...

Oh I love some respect for language, we're all guilty of some misuse, it's never too late to acknowledge and be patient and informative to others! I could bring up "lattice", "Bragg reflections", and "n-dimensional" (n=0,1,2,3), but I already discuss it here: pubs.rsc.org/en/Content/A... #chemsky

I have not been active on Bluesky for quite some time, but I think it's time to come back. Hopefully the #chemsky community still is alive and kicking. :)

Oh, Marzena @marpander.bsky.social also joined, what a day! 🌟 Welcome! #MOFsky

🥁🥁🥁 we have a new #MOF #Bluskywalker! Welcome Wojciech @wojbur.bsky.social 🎊

🧐 ... there's probably some non-human presence deciding if I passed the "human identity" test, failing if we assume that the image was relevant

➡️ 48 hours left. IUCr2026 abstract submissions close midnight Feb 15. Submit your work now. ➡️ event.fourwaves.com/... #IUCR2026 #IUCR #crystallography

Oh yes, and I hope you'll soon find out it's still growing! Everyone: 📢 give a "Follow" to @momentum-transfer.com if you want to keep up with one of the most exciting partners of academia in accessible crystallographic services, especially #totalscattering ! 🌟 #crystallography #scisky #chemsky

... and as if that wasn't special enough, I had the chance to give a 1-day workshop on single-crystal diffraction and #3Dtotalscattering to more than 30 (!) enthusiastic students — exactly on 'Fat Thursday'. Who else had free delicious paczki making a surprise appearance during their lectures? 😏

He was probably friends with this guy

Without naming your job, tell me something you say over and over again at work. "... can I see the raw data?"

Registration for the 11th ECA crystallography school is now open! It will be held in Stockholm on the 28th of June to the 4th of July and will give practical experience of solving and refining data from both powder, single crystal and electron diffraction. www.ecs11.org forms.gle/ckyFQoNqRd7d...

With more single crystals synthesized, I plan to resolve the remaining structures together. I am hopeful this final set will yield significant findings to cap off a productive year.🧪 #chemsky #MOFs #Single-Crystals #CoordinationChemistry

I've been proposing my solution for a decade now: if you publish one paper as corresponding or first author, you bring cake. I'll leave you predictions on what would happen, but certainly the number of publications would drop like a step function. #ChemSky #AcademicSky

Among the many new territories I will explore in 2026, an exciting one is joining IUPAC and contribute to global science and education in this capacity as well 😌 I look forward to engaging with the community on my Division's subject: Chemical Nomenclature and Structure Representation! 🫸 #ChemSky

Back in office to find a lovely gift from the OlexSys team... their iconic photographic calendar! 🫶 Very relatable image to kickstart January 2026: "Ants on a mission" - Irrelevant to the naive eye, resolved, and slowly but surely building much bigger things than themselves. 🐜

More interesting stats by anisota.net/harvest Cryptic combinations emerge, probably a message from a greater consciousness from a parallel (reciprocal?) dimension: "Lattice scientists" "Hope symmetry" "Paper crystals" "Disordered community" and most importantly... "Soon Science" 😌

📢!! After nearly a decade looking for my place in academia, I am incredulous to announce that in 2026 I'll start as research Professor at Ewha University in Seoul, and visiting PI at ShanghaiTech! I'm so thrilled to get closer to my Asian friends 🍻 and finally realize my scientific vision! 🎆 #MOFs

Biggest commitment to a 3 second joke I've ever seen
