Rise velocity of small polyolefin plastics in a seawater tank exposed to natural conditions in Hawai’i

open access: yesEnvironmental Research Communications
Floating plastic is ubiquitous at the ocean surface, but the transport mechanisms associated with the type of particle and the effect of environmental parameters, including the presence of a biofilm on the polymers, are very limited.

Treatments on Polypropylene Macro Synthetic Fibers for Improving Adhesion in Structural Concrete Reinforcement: A Systematic Review

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 20, May 20, 2026.
Surface functionalization of polypropylene macrofibers to enhance fiber‐matrix interfacial bonding. ABSTRACT Concrete is the most used higher compressive strength‐building material, albeit brittle to tensile, and flexural loads. Polypropylene (PP) synthetic polymeric macrofibres are commonly employed as reinforcement material to prevent this situation ...

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Auxeticity‐by‐Assembly: Interlocking Modular Auxetic Metamaterials with Selectively Activatable AgNW–Graphene Oxide‐EGaIn Composite Interconnects for Scalable Freeform Photovoltaic Modules

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
Auxeticity‑by‑Assembly converts freeform photovoltaics from cut‑defined layouts to assembly‑defined systems. Standardized interlocking units generate negative‑Poisson‑ratio, reconfigurable architectures, while hinge regions are wired by selectively activatable AgNW–GO@EGaIn composite interconnects and a folding‑enabled interconnector layer. A decimeter‑

Fluorometric Detection of Sarin Vapor Using Fluorene and Fluorenone Derivatives

open access: yesAnalysis &Sensing, Volume 6, Issue 3, May 2026.
In this study, we present the detection of the actual nerve agent sarin in the gas phase, assessing more than twenty fluorene and fluorenone derivatives as organic fluorescent probes. One molecule in particular showed very promising results in terms of stability and selectivity.
