An Open-Source, Low-Cost Thin-Layer Chromatography Plate Cutter
Thin-layer chromatography (TLC) is widely used in teaching and research laboratories, but TLC plate cutters remain expensive, with most commercial models priced above $800 USD. This article presents a...

Illuminating new research offers chemists a simple and mild method for making arynes—a challenging type of strained molecule. Using a new precursor activated by blue light, researchers were able to access elusive aryne intermediates. cen.acs.org/synthesis/re... #chemsky 🧪
Let there be light-activated arynes
Making these strained intermediates just got easier, thanks to new precursors that react in the presence of blue light

Check out our latest collaboration now out in Nature. It's been an absolute pleasure to be able to contribute this and work with Courtney and her talented students.
Our group’s latest work is out today in @nature.com ! Our goal is to enable any chemist to be able to easily access an aryne intermediate! So Chris, Sal, and Felicia teamed up to design what we think is the ideal aryne precursor. Danny and @jnboyn.bsky.social helped us understand the activation!

We served over 151 million (!) free meals to students last year, saving families an average of $1,000 per student.
Students should be able to focus on the classroom, not on where their next meal will come from. We’ve made that a reality in Minnesota.
