Researchers tested an impact-oscillation method for improving the mechanical properties of high-strength titanium alloy sheets. This is a metallurgical engineering paper unrelated to environmental microplastics.
Investigation of the adsorption behavior and adsorption mechanism of pollutants onto electron beam-aged microplastics
Researchers used electron beam technology to age microplastics and then studied how this aging changed the particles' ability to adsorb pollutants from water. They found that electron beam-aged microplastics had significantly higher oxygen content on their surfaces and were more effective at capturing certain contaminants. The study suggests that as microplastics degrade in the environment, they may become more efficient carriers of pollutants.
The potential of electron beams for the removal of microplastics from wastewater and sewage sludge
Researchers investigated whether electron beam treatment could help remove microplastics from wastewater and sewage sludge, finding that the high-energy electrons altered the surface charge of plastic particles, causing most types to clump and settle.

Modern Innovations and Applications in Plasma Electrolytic Oxidation Coatings on Aluminum, Magnesium, and Titanium
This review covers plasma electrolytic oxidation (PEO), a technique for creating protective coatings on metals like aluminum, magnesium, and titanium. The coatings have applications in batteries, biomedical devices, water treatment, and energy production. While not directly about microplastics, the water treatment applications of PEO coatings are relevant to developing better filtration and remediation technologies for removing plastic particles from water.

This biomedical engineering study compared the properties of surface coatings applied to titanium and titanium-zirconium-niobium alloys for use as medical implants. The research aims to improve implant biocompatibility and reduce infection risk, with no direct relevance to microplastic or environmental research.
Application and Lightweight Research of New Aluminum Alloy Materials in Automotive Components
Despite its title referencing lightweight materials for vehicles, this paper studies new aluminum alloy compositions designed to reduce car body weight while improving strength and corrosion resistance — not microplastic pollution. It examines alloy microstructure and mechanical performance for automotive applications, and is not relevant to microplastics or human health.
