While reviewing I saw another reviewer lamenting that a material's behaviour has been known for decades, while the article is on a new perspective on it. Might be controversial, but I'm sure that discovering new things is more popular and less significant than discovering new ways to look at things.
Do diffraction, have fun, they say... @stecanossa.bsky.social , an analysis by single picture? :) #crystallography #chemsky
I can be considered as experienced crystallographer (>1100 structures, X-ray, neurons, electrons, powder, VT, HP, in situ, in operando, etc, bla-bla), but almost every day, working with small and "simple" molecules, I am asking the question "What The Hell It Is?!" #chemsky #crystallography
Tartaric Acid Crystals I intended to make these right after making the sodium ammonium tartrate crystals, but they kept turning into polycrystals. It actually took quite a bit of effort to grow a single crystal.
I just found out that a tradition of the yearly Chinese dragon boat festival (which ended recently) is drinking realgar wine and my mineral geek side was "oh realgar is so cool" but 100 ms later the chemist side kicked in and "no way it's not just a name..." (apparently it's not) 🫥 🐉
Last week the one an only @furukawas.bsky.social visited @uniulm.bsky.social and gave a fantastic talk on cages, MOFs, and anything in-between. We got a bit confined in our discussions on dynamic frameworks and started a new tradition - Guest Portrait on dry plates with historical camera.
I will just recrystallize this iron food supplement, maybe I will get crystals. Few days later, looking on the crystals: - WTF? What The Framework, I mean? Why MIL-88A? I did not ask for it or any other MOF! Looks like #MOF are inevitable. #chemsky #crystallography
My longest-time favourite crystal growth artist is here! 🤩 Anyone "captured for life by symmetry and by crystals": this is a special one to follow 🌟 #crystallography
manzana@manzana-crystal.bsky.social · 2mo agoThese are crystals of ammonium sodium tartrate (the left is the L-form, and the right is the D-form). The D- and L-form tartrate ions are mirror images of each other, and this relationship is preserved all the way through to the crystal structure.
The thrill of seeing clean systematic absences in the peaktable hits me every time, exactly as it did a decade ago... it really never gets old. I don't think this is normal but it feels good so yay! 🫠 #crystallography

I would need a good dose of rationality to avoid eating them, they look so gummy 😐

Nice gadget idea for MOF2026 by @antonpaar.bsky.social, after all that's how Robson started it.. although I could not find a way to make Td nodes. Plenty of time to upgrade it for EuroMOF2027 😏
Our tutorial on gas sorption measurements in MOFs is now available #OpenAccess! We bring together the practical workflow and data analysis basics in a beginner-friendly guide. Hope it will be a useful resource for students and researchers entering the field! @pubs.acs.org doi.org/10.1021/acsm...
Gas Sorption Measurements in MOFs─A Tutorial for Beginners
Adsorption measurements belong to the primary characterization tools used to determine the textural properties of porous solids such as Brunauer–Emmett–Teller (BET) area, pore volume, and pore size distribution as well as to estimate the energy of host–guest interactions. Accurate description of gas sorption in metal–organic frameworks (MOFs) is crucial for evaluating their performance and provides key insights into textural properties such as adsorption capacity, pore volume, and pore size distribution. This tutorial paper aspires to provide a practical guide for graduate and undergraduate students, as well as researchers who are new to the field, on low-pressure gas adsorption measurements (up to atmospheric pressure). Key aspects such as sample preparation, activation strategies, adsorption measurement techniques, data analysis, and reporting are discussed in detail. We believe that this Tutorial could serve as an entry-level teaching resource for gas sorption measurements in MOFs.

This, my friends, is going to be quite something... Let me put it this way 😌 - stay tuned!

This is such a beautiful structural work by @mirceadinca.bsky.social, @jules-oppenheim.bsky.social and co-workers... The rising #MOF #totalscattering star Jules is getting brighter and brighter! 🌟
Jules Oppenheim@jules-oppenheim.bsky.social · 3mo agoExcited to share our most recent paper! We investigate the structure of LnHOTP, the only proven metallic MOF which induces a charge density wave phase. This tour-de-force contains diffuse scattering, aperiodicity, and high pressure synchrotron XRD. Read about it here: pubs.acs.org/doi/10.1021/...
