Have you ever wondered how types of scientific glassware got their names? This article tells the stories of men like La Marquis de Burette, Justus von Liebig and Jan Wółumétrič. PDF: immaterialscience.org/s/Glas…

📰Congratulations to Paulina who has just published her first first author paper from her PhD doi.org/10.1039/D5SC04881H and her #MyFirstChemSci @ChemicalScience looking at coordination sphere interactions driving isomer selectivity in heteroleptic cages with low-symmetry ligands

Does crystallisation in Tin–Lead perovskites really stop once the solvent evaporates? ❌ In @J_A_C_S, @dyyagcl shows dynamic PL changes during cooling, suggesting crystallisation continues, refining order and boosting radiative recombination. pubs.acs.org/doi/10.1021/jac…

Our pipeline to compute thermal barriers of photoswitches💡 is out!🥳 We especially focused on NBDs for MOST🔋 and imines, but also stilbenes and DAEs. Try it out! You need just chemdraws and freeware to get libraries computed doi.org/10.1002/cptc.2025001…

Our work on an all-photonic logic gate with a photochromic dyad works in solid-state and uses infrared as output. Just accepted in @RSC_ChemSci! Congrats @I_Sariful_ and @Jakir7_ Thanks to @ANRFIndia, @iiserkol, and @dcsiiserkol. pubs.rsc.org/en/content/arti…

Episode 6 of our photoswitchable imines... Thrilled to show our new work of N-Alkyl imine photoswitches! Now on @J_A_C_S 👇🏻🍻💡
🚨📢Improving the photoswitching properties of N-alkyl imines, out now in @J_A_C_S 🤔Insights from our previous work led @GalliumWu, Lasse, and I to tune the properties of these N-alkyl systems🛠️, where we also observed isomer-dependent fluorescence!💡🔦🚥 doi.org/10.1021/jacs.5c02404

Our first photoswitchable channel, controlled by three separate stimuli, up now@ChemRxiv! tinyurl.com/3m4umy3d - we use F-azobenzenes and a pillar[5]arene core to control ion transport + light, pH, and guest, modulating initial rates 170-fold. Collaboration + @markianwallace!

Can't believe we made it 😆
🚨📢Out now in @Chem_CP , @GalliumWu and I figure out how to perturb a non-photoresponsive reaction(🌚) out of equilibrium using our imine-based photoswitches🔦💡This is achieved using a light-responsive transimination!(🌝) #AIPs #imine #OpenAccess doi.org/10.1016/j.chempr.202…
