that's amazing work and very life-like. I know what you mean about the materials and it's a pity, because I feel like that's unnecessary. There's a tremendous body of work on substitutes for polymers that are currently made from petrochemical feedstocks, but it all remains very small-scale and mostly academic because the petrochemical industry does NOT want to interrupt the pipeline they've constructed: straight out of the Earth and flowing into every conceivable consumer product.
we would love to be able to make our own plastics at the Pnictogen Wing homestead, from biomass. so that prompts the question: what living creature would be (a) easy to grow or culture in the relatively limited space available in a single-family home with a yard, and (b) the most fruitful as a feedstock for production of a useful polymer?
I already know a little. furfural (furan-2-carboxaldehyde) and 5-hydroxymethylfurfural are two attractive candidates for a biomass-derived chemical that could be used to make plastics. Furfural can be obtained from the acid-catalyzed hydrolysis of pentosans, biopolymers of five-carbon sugars found in such substances as corncobs and oat hulls. 5-hydroxymethylfurfural can be obtained in a like method from the breakdown of cellulose, starch, etc.

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.

what is the best name for any theory about polymers and why is it reptation?

Attending my first Faraday Discussion and it seems really challenging for the speakers and editorial team but is very rewarding as an attendee. I don't want all chemistry conferences to have this format, but it would be wonderful if more did. #FaradayDiscussion #RSC #polymers #polymerisation #depolymerisation
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.
