Happy to share the first published work from my PhD! When I started 3D printing thermosets in my first year, I was immediately frustrated with the process. Resins took ages to prepare AND didn't last long. @JacobJLessard1 and I cooked up this technique to solve the first

Check out our paper hot off the press! One of my last (co)1st author papers from postdoc. https://t.co/2R7d5bqKp8
pubs.acs.org
Frontal ring-opening metathesis polymerization (FROMP) offers an energy-efficient method for manufacturing high-performance thermoset resins. However, the background reaction attributed to ring-ope...

Our undergrad Rodrigo wondered if we could replace the bespoke chiral acid used in our recent asymmetric photochemistry with commercial (S)-TRIP. His protocol for enantioselective truxinate synthesis on 2-gram scale just dropped on @OrgSynth: https://t.co/Af1e9Yq2TS
