A poem by my colleague Orchid Tierney that comes, in part, from the course we've now twice taught together.

Fantastic new paper by the absolutely brilliant and delightful Brooks Abel and his first post-doc Zohaib Siddiqi (now at Auburn). Beyond the high efficiency in circularity of this monomer-polymer system, this work has the potential to redefine how we have thought of living or immortal polymerizations. Plus, really thoughtful catalyst design. #chemistry #polymers #recycling https://onlinelibrary.wiley.com/doi/full/10.1002/ange.1570414

A long-theorized material has become reality: DNA-based Olympic gels. Their structure is stabilized not by chemical crosslinks, but by mechanically interlocked molecular rings. A striking example of how geometry and topology shape material behavior.

My friends did a thing! Microplastics are very challenging to measure and some existing protocols make it worse. To be clear, the authors are concerned about microplastics, and also concerned that we have analytical methods that will give us real information. Good and difficult work. #analysis #chemistry #polymers #plastics #microplastics

Fantastic paper from Brooks Able at Berkeley using an organic catalyst to achieve high molecular weight for poly(THF) via cationic ring-opening polymerization. The low ceiling temperatures of these polymers make them attractive targets for reversible polymerizations, but it has previously been really hard to get to the molecular weights required for good mechanical properties. #chemistry #polymers #JACS https://pubs.acs.org/doi/10.1021/jacs.5c18359

Proper Curing: Not an additive, but THE most critical factor. Concrete doesn't "dry"; it cures through a chemical reaction (hydration) that requires moisture. For maximum strength, keep the concrete surface continuously moist for at least 7 days (using plastic sheeting, damp burlap, or a curing spray). Un-cured concrete can lose 50% of its potential strength. #fly ash #polymers #concrete #materials science

♻️🌍 #Rutgers scientists have developed #plastics engineered to break down on demand at controlled rates – think days, months, or years – using a chemical strategy inspired by how natural #polymers like #DNA degrade.
The #discovery offers a practical solution to plastic #pollution by allowing everyday materials to decompose safely without harsh #chemicals or special conditions.

https://phys.org/news/2025-09-reveals-sulfur-based-blocks-sustainable.html
Sulfur atoms enhance the #sustainability of #polymers because the bonds between carbon and sulfur atoms are easier to break than the bonds between carbon and other carbon or oxygen atoms. This allows sulfur-containing plastics to degrade…
"…we were able to establish a predictive rule that indicates which sulfur-based building blocks yield perfectly structured and clean polymers—and which do not," so Prof. Dr. Alex Plajer, Jr Prof, Macromolecular Chemi, Uni Bayreuth.
