A Review of the Sampling, Analysis, and Identification Techniques of Microplastics in the Air: Insights into PM2.5 and PM10

Lucia Solórzano, Dayana Gavilanes, Francisco Cadena, Lourdes Irusta et autres

The massive use of plastics has raised growing environmental concerns, including microplastic (MP) pollution. While most studies have focused on MPs in aquatic environments, research on airborne microplastics has gained increasing attention in recent years. This review discusses the sampling, analytical, and …

Improving the properties of carbonated soybean oil-based non-isocyanate polyhydroxyurethane networks: Copolymerization versus hybridization with epoxy resin

Nahikari Martin-Larrañaga, Iker Razquin, Nora Aranburu, Oihane Sánz et autres

Carbonated soybean oil bio-based polyhydroxyurethanes (PHUs) produced without isocyanates often have inferior properties compared to their traditional isocyanate-based counterparts. To improve these properties, this study presents two strategies: copolymerization with other carbonated monomers and hybridization with epoxy monomers. Carbonated soybean oil (CSBO) …

Comparative Life Cycle Assessment of Recyclable Polyhydroxyurethanes Synthesized from Five- and Six-Membered Carbonates

Pauline Bron, Olivier Talon, Camille Bakkali‐Hassani, Lourdes Irusta et autres

Polyhydroxyurethanes (PHUs) synthesized from cyclic carbonates are promising alternatives to conventional polyurethanes due to their advantageous isocyanate-free synthesis and reprocessability characteristics. While many studies focus on PHUs derived from five-membered cyclic carbonates (5CCs) for more sustainable synthesis routes, PHUs from six-membered cyclic …

Fully Recyclable Pluripotent Networks for 3D Printing Enabled by Dissociative Dynamic Bonds

Marco Caliari, Fernando Vidal, Daniele Mantione, Guillem Seychal et autres

Abstract Additive manufacturing (AM) has risen in popularity due to its ability to produce complex shapes in a material‐efficient way. However, to produce objects with advanced properties, complex multimaterial strategies are often employed. This one‐polymer‐one‐property paradigm significantly slows down the application of …
