Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Exploring the Transferability of Image‐Based Algorithms for River Plastic Detection: The Value of Small Mixed Data Sets

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Using large image data sets has been the conventional strategy to improve object detection, but it increases annotation effort and training cost and does not guarantee robust transfer to new sites. Here we quantify the value of a small, diverse training set for floating macroplastic detection by jointly evaluating performance, computational ...

Suitability of river plastic monitoring methods for citizen science

Cambridge Prisms: Plastics
Rivers act as long-term plastic storage and a pathway for land-based plastic pollution into the ocean. Monitoring river plastic at a global scale remains challenging, with only limited large-scale and long-term monitoring efforts to date. Citizen science

Pollution to Solution: Understanding and Addressing Microplastic Contamination in the Environment

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT In general, plastic pollution results from the unintentional release of macroplastic materials into the environment as well as the deliberate production and usage of small plastic particles (micro‐ and nano‐sized plastic particles) in a variety of consumer products micro and nanoplastics in filtrate freshwater and marine environments because ...

No escape from microplastics: Contamination of reef manta ray feeding areas in a remote, protected archipelago

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
We found microplastic contamination of the upper water column around the Chagos Archipelago, a remote, protected archipelago in the central Indian Ocean. Key aggregation areas for reef manta rays (Mobula alfredi) were contaminated, putting them at risk of microplastic ingestion.

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.

Multiobjective Environmental Cleanup with Autonomous Surface Vehicle Fleets Using Multitask Multiagent Deep Reinforcement Learning

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This study presents a multitask strategy for plastic cleanup with autonomous surface vehicles, combining exploration and cleaning phases. A two‐headed Deep Q‐Network shared by all agents is traineded via multiobjective reinforcement learning, producing a Pareto front of trade‐offs.

Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...
