Macromolecular Rapid Communications, Volume 47, Issue 4, 20 February 2026.We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...

A Shape‐Based Model for Drag and Terminal Velocity of Non‐Spherical Plastic Particles
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Plastic pollution in rivers is governed by how individual particles move among the bed, the water column, and the free surface, processes that depend primarily on drag and terminal velocity. Although plastic particles span a much wider range of shapes than natural sediments, many existing drag and terminal‐velocity formulations still rely on ...

Surfing Transport of Buoyant Objects Observed in the Nearshore
Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.Abstract Free‐drifting buoyant objects, including plastics, marine debris, and organisms, move with the wind, waves, and surface currents. These objects also surf on breaking waves; this process adds to the total transport of the objects and can control beaching.

From macroplastics to microplastics: Role of water in the fragmentation of polyethylene [PDF]
Chemosphere, 2019 In this work, the artificial photodegradation of polyethylene films was studied in laboratory to compare the fragmentation pathways of this polymer at air and in water. Oxidation, surface mechanical properties, crystallinity and crack propagation were monitored to investigate their influence on fragmentation.

A Critical Evaluation of Nano‐ and Microplastics: Sources, Health Risks, and Mitigation Strategies
Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.Microplastics (1 μm–5 mm) and nanoplastics (< 1 μm) have become ubiquitous contaminants across air, water, and soil systems, with growing evidence of their presence in human tissues including blood, lungs, and even the placenta. While microplastics have been extensively studied, nanoplastics remain poorly understood because of their minute size and ...

Same but Different: A Framework to Design and Compare Riverbank Plastic Monitoring Strategies
Frontiers in Water, 2020 Plastic pollution in rivers negatively impacts human livelihood and aquatic ecosystems. Monitoring data are crucial for a better understanding of sources, sinks and transport mechanisms of riverine macroplastics.

Journal of Basic Microbiology, Volume 65, Issue 10, October 2025.ABSTRACT In this study, we present Methylobacterium aquaticum A1, a novel strain capable of degrading polyester polyurethane (PE‐PUR). The attachment of M. aquaticum A1 to PE‐PUR and its degradation capabilities were verified using Scanning Electron Microscopy (SEM) and Fourier‐Transform Infrared Spectroscopy (FT‐IR).
