(1/3)🚨 Excited to share Lidón’s and Max’s work on #photoswitchable #MetalloSupramolecular capsules, with a #MolecularRatchet and #OutOfEquilibrium structures, in @chemicalscience.rsc.org! 👀https://doi.org/10.1039/D5SC09472K #KrbekGroup #ProudPI #SupramolecularChemistry #ChemTwitter #WomenInSTEM

Hi folks, I’m on the ballot for President of the @rsc.org. I’m standing because we live in post-truth times where respect for expertise & evidence can no longer be taken for granted. It’s time to push back. If that resonates, RSC members can vote here www.mi-vote.com/secure/rsc 🗳️🙏

Our new video, created by Stuart Jantzen (Biocinematics), depicts the original Maxwell’s Demon thought experiment 😈 tinyurl.com/3ja25xfz, the archetypal information ratchet that inspires how we design molecular motors & pumps: tinyurl.com/msn8c2an; tinyurl.com/yj53rfvm; tinyurl.com/557vcubt 👹

New paper published on the near-quantitative formation of imines in water ! with Tommaso Marchetti Lorenzo Goldin @benjaminoacid.bsky.social @deepaky25.bsky.social Federico Rastrelli and Luca Gabrielli pubs.acs.org/doi/10.1021/... #ChemSky

Out today in @natchem.nature.com 😃 Huakui, @stefanborsley.bsky.social @benjaminoacid.bsky.social & co illustrate why catalysis-driven motors (like motor proteins) can't use designs based on light-driven motors or molecules-that-rotate-through-multi-reaction-sequences www.nature.com/articles/s41...

When liquids freeze, ions normally grind to a halt — but not in our new materials! Our latest paper in @science.org shows how organic salts can keep the same ionic conductivity mechanism as they transform from liquid to solid. 🔗 www.science.org/doi/10.1126/... @ox.ac.uk @ajavestro.bsky.social

Interested in active transport, taxis, or light-driven systems? Our latest work may catch your curiosity: shorturl.at/ApOse A structurally simple molecule can transport multiple anions against their concetration gradiend (a form of phototaxis). 👇

Chemistry involves such large and small numbers that it’s often hard to take in just how fast some processes occur. Dethreading a ring off the open end of a chain when there are no binding interactions present, or passing the end of one strand past another, are incredibly fast processes...

We just published a photoswitchable amphiphile that abruptly assembles into ellipsoids over 1h after the light is switched off! #ozchem #ChemSky chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/...

Information ratchets drive many molecular motors, but we can also use them for other nonequilibrium processes like performing error correction in a molecular recognition process to increase selectivity. Published today in @natnano.nature.com www.nature.com/articles/s41...

'Ullo @jacs.acspublications.org, Hua-Kui, Axel, @benjaminoacid.bsky.social & @stefanborsley.bsky.social have gotta new motor! doi.org/10.1021/jacs...

Can you work out how fast a molecular motor rotates from in situ measurments? Turns out that yes, you can, as we show today in @jacs.acspublications.org pubs.acs.org/doi/10.1021/... @profdaveleigh.bsky.social @stefanborsley.bsky.social

People didn’t “used to be fine” without air conditioning during heat waves in the U.S. - a lot more people *just died*. According to this study, air conditioning has cut heat deaths in the U.S. by around 80% since 1960. papers.ssrn.com/sol3/papers....

Supramolecular chemistry has officially "grown up" in Germany. On behalf of the 10-person Founding Team👇, I am happy to announce the creation of section SupraChem within the German Chemical Society! 🍾 GDCh members please consider joining asap via www.gdch.de/suprachem @gdch.bsky.social

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated. Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...

Check out how we made a minuscule motor rotate 24 times in one direction on its own! Huge thanks to all involved, especially @profdaveleigh.bsky.social for making this work possible @pubs.acs.org Huakui, Axel, @stefanborsley.bsky.social @benjaminoacid.bsky.social & Alex pubs.acs.org/doi/10.1021/...

I’m excited to share that I will be moving to the University of Ulm as a junior group leader and I have a fully-funded open PhD position co-supervised by me and Max von Delius @mvdelius.bsky.social . Apply at [email protected], any shares would be appreciated! www.bmwrlab.com/work-with-us

I have run out of patience with the apparent silence of most US science institutions (and not just US) in the face of Trump & Musk's rampage. There are of so many facets of that, but in this column for @chemistryworld.com I talk about the assaults on inclusion. www.chemistryworld.com/opinion/scie...

A really fun project, delivered on the back of Peng-Lai’s fantastic efforts, ably assisted by Martin and of course our collaborators in Strasbourg, Alessandro and @giusepponelab.bsky.social, who taught us lots of polymer and materials chemistry. Thanks all!

Come and join my new group! We have two funded PhD positions available in the areas of supramolecular chemistry and polymer nanotechnology. See fieldengroup.net for more details! Reposts much appreciated!

If you've ever read about molecular motors, you've probably wondered about "power strokes." We looked into that by simulating a catalysis-driven molecular motor explicitly 🧐 I am super happy to share my latest work with Alex, Geyao, and Todd @nuchemistry.bsky.social pubs.acs.org/doi/10.1021/...

I am going to try to start again with my thread on the history of pH; I had something of a thread on the other site but forgot to save it before I deleted my account. The thread will spread in time over weeks/months, so bear with me. #chemsky #histstm
