- I just found this photo of one of the most disgusting preparations of my entire training… PU foam! First, a highly branched polyester was synthesized from adipic acid, oleic acid, and phthalic anhydride with 1,1,1-tris(hydroxymethyl)propane using PTSA as an acid catalyst. The polycondensation ran for many hours at ~190 °C under nitrogen and vacuum while water was continuously removed as a by-product. During the reaction, the acid number (determined by titration, mg KOH/g) was monitored until it dropped below 10, with a target around 5. The resulting viscous polyester polyol was then reacted with tolylene-2,4-diisocyanate to produce rigid polyurethane foam. […]

- Great talk by Mathijs Mabesoone at #Lunteren2026. He talked about the use of automated synthesis and characterization of peptides as a basis for data-driven discovery of peptides with new properties on the example of general design-rules for peptide surfactants.#Chemistry #Surfactants #Robotics
- Interesting talk by Antonio Echavarren at #Lunteren2026. He talked about the use of gold-carbene catalysis to perform complex and enantioselective transformations in organic synthesis.https://pubs.acs.org/doi/10.1021/jacsau.3c00159#Synthesis #OrganicChemistry #Chemistry #Catalysis
- Great talk by Dmitrii Nagornîi from the group of Timothy Noël at #Lunteren2026. He talked about the late-stage modification of aryl compounds with NCF3 and SCF3 groups using flow chemistry.https://chemrxiv.org/doi/full/10.26434/chemrxiv.15000577/v2#Chemistry #FlowChemistry
- Happy birthday to chemist William Henry Perkin (1838-1907)! This lino block print ‘William Henry Perkin Discovers Mauve’ is about how the British chemist & entrepreneur made the serendipitous discovery of the 1st synthetic organic dye: mauveine. Perkins entered the Royal College of Chemistry in London in 1853 when he was only 15, studying with August Wilhelm von Hofmann. 🧵1/https://minouette.etsy.com/listing/955324548#linocut #printmaking #sciart #chemistry #histsci #mastoArt
- Today in the classroom:First year chem is planning a gas collection lab. Things like doing conversions & stoichiometry to be ready to get to work tomorrow morning.Second year chem is writing up their Ca(OH)2 solubility lab.I woke up with a crushing sinus headache. I'm hoping it's just the major pressure shift we had this week with the weird weather and not another cold.#teaching #chemistry
- Great to hear the full story of this exciting project that is done in collaboration with, among others, Madeline Kavanagh, of our @LED3hub. (2/2)#ChemBio #Chemistry #Synthesis #SAR #Tuberculosis #Virulence #ABPP #PAL
- 🚀 Great news for chemical research!💻 Release of #Chemotion #ELN 3.0.0 out! 🎉 The latest update to our electronic laboratory notebook brings numerous improvements and new features that make managing your research data even more efficient and #FAIR.👇 t1p.de/0lk2o #Chemistry
- Insightful talk by Varinder Aggarwal from the University of Bristol at #Lunteren2026. He talked about efficient synthesis procedures through Iterative chemistry enabled by boron. He presented e.g. the synthesis and structural annotation of baulamycins A.https://www.nature.com/articles/nature23265#Chemistry #Synthesis #boron #iteromics
- Excellent #OrganicSynthesis is the basis of so many exciting #ChemBio projects. Nevertheless, we often do not present much of the synthesis that we do.Therefore, I am very happy to be at the Dutch Symposium on Organic Chemistry #Lunteren2026, where organic synthesis will take the center stage for the next 2 days.#Chemistry #OrganicChemistry #Science #Conference
- Getting started with a full week of #Science #conferences. I will be at #Lunteren2026 and #KNCVMCCB2026 by the #KNCV and at #Biochemistry2026 by @GDCh_BioChem. Looking forward to learning about exciting science and (re-)connecting with many scientists.#ChemBio #Biochemistry #Chemistry
