Iron-catalyzed [2+2] oligomerization of butadiene produces (1,n’-divinyl)oligocyclobutane, a new polymer that can be chemically recycled. Credit: Figure by Jonathan Darmon of the Princeton University Department of Chemistry New polybutadiene molecule enchains in squares, a microstructure that enables it to depolymerize under certain conditions, advancing options for closed-loop recycling. As the […]

Based on different commercially available raw materials (e.g., TiO2-mica, Fe2O3-mica), a variety of all-natural bioinspired structural materials with different colors can be fabricated.

The industry opts out to use sustainable materials due […]

Stand in the soda pop aisle at the supermarket, surrounded by rows of brightly colored plastic bottles and metal cans, and it’s easy to conclude that the main environmental problem here is an overabundance of single-use containers: If we simply recycled more of them, we’d go a long way toward […]

There is a credible pathway to significantly reduce ocean plastic flow into the ocean, but only if all solutions are implemented. Credit: (c) The Pew Charitable Trusts/SYSTEMIQ ENLARGE Research lays out viable pathway to “break the plastic wave.” A new analysis by The Pew Charitable Trusts and SYSTEMIQ finds that […]

New research from NUI Galway and the University of Limerick has for the first time quantified the volume of plastic from European countries (EU, UK, Switzerland and Norway) that contributes to ocean littering from exported recycling.

On the surface of the newly developed catalyst (PtGa-Pb/SiO2), Pt1 sites remain exposed to facilitate catalytic reaction while Pt3 sites (and Ga3 sites) shown with triangles are blocked by Pb.

Mussels clumped together on rocks at Whitsand Bay in Cornwall, England. Credit: University of Plymouth Commercially important seafood species are at greater risk of microplastic contamination depending how they clump together in the marine environment, new research suggests. In the first study of its kind, scientists from the University of […]
