ClearEffect of Laser Shock Peening on the Microstructure and Properties of the Inconel 625 Surface Layer
Researchers investigated how laser shock peening affects the microstructure and mechanical properties of a high-performance nickel alloy. While unrelated to microplastics directly, understanding metal alloy behavior under stress is relevant to designing durable infrastructure that resists the mechanical wear that generates metal and polymer particles.
Effects of Pulsed Magnetic Fields of Different Intensities on Dislocation Density, Residual Stress, and Hardness of Cr4Mo4V Steel
This paper studied how pulsed magnetic fields affect the internal stress and hardness of a bearing steel alloy. While unrelated to microplastics, research on material durability is relevant to reducing wear-generated particles from industrial machinery, which can contribute to microplastic and metal particle pollution.
On the Formation and Characterization of Nanoplastics During Surface Wear Processes
Researchers characterized nanoplastic particle generation during surface wear processes, finding that mechanical abrasion of bulk plastic materials produces a broad size distribution of particles including sub-100 nm fragments, with surface wear rate depending on polymer hardness and contact conditions.
Thermo‐based fatigue life prediction: A review
Not relevant to microplastics — this review covers thermography-based methods for predicting the fatigue life of metals under cyclic stress, with no connection to plastic pollution or environmental health.
The effect of heat flow from friction forces on the surface of the billets
This engineering study examined how friction-generated heat affects the surface of ceramic billets during grinding operations. The paper is an industrial manufacturing study and is not related to microplastics or environmental health.
Effect of Cryogenic Treatments on Hardness, Fracture Toughness, and Wear Properties of Vanadis 6 Tool Steel
Researchers investigated how different cryogenic and tempering treatments affect the hardness, fracture toughness, and wear properties of Vanadis 6 tool steel. The study found that specific cryogenic treatment protocols can significantly improve the mechanical performance and durability of the steel. While not directly related to microplastics, the findings are relevant to developing longer-lasting industrial tools that generate less wear debris.
Dynamic Processes of Substructural Rearrangement under Friction of Carbon Steel
This study examined how heat treatment affects the friction and wear properties of medium carbon steel, linking material microstructure to tribological performance. The research is focused on materials engineering with limited direct relevance to microplastic pollution or human health.
The effects of oil-quenching and over-tempering heat treatments on the dry sliding wear behaviours of 25CrMo4 steel
Researchers tested how different heat treatments affect the wear resistance of 25CrMo4 steel used in automotive parts, finding that oil-quenching and over-tempering significantly reduced material wear loss compared to untreated steel, even when hardness slightly decreased — important for extending the life of industrial components.
Study of Wear Resistance of Cylindrical Parts by Electromechanical Surface Hardening
Researchers investigated electromechanical surface hardening (EMSH) as a technology for increasing the wear resistance of cylindrical parts, specifically protective sleeves of cantilever pumps, analyzing how different processing modes and schemes affect surface microhardness. They found that EMSH can achieve microhardness improvements to depths of up to 1.2 mm, with the specific mode and scheme determining the resulting surface layer hardness and wear resistance.
Resistance of Heterogeneous Metal Compositions to Fracture under Dynamic and Cyclic Loads
This study examined how heterogeneous multilayer metal composites resist fracture under dynamic and cyclic loading, finding that layer boundaries retard crack propagation compared to homogeneous materials. The findings are relevant to materials engineering for durable structures, though not directly related to microplastic research.
Variation of the Vibrational Treatment on Mechanical Properties and Weld Residual Stress
This materials engineering paper examines vibrational treatment as a cost-effective alternative to heat treatment for relieving welding residual stresses in metal structures. The study is unrelated to microplastic pollution research.
New Methodology to Evaluate the Rolling Contact Fatigue Performance of Bearing Steels With Surface Dents: Application to 32CrMoV13 (Nitrided) and M50 Steels
This engineering study developed a method to evaluate how surface dents affect rolling contact fatigue in bearing steels, using indentation testing and two-disk fatigue experiments to compare different steel alloys. This is an industrial engineering study with no relevance to environmental microplastics.

A study using X-ray diffraction and electron microscopy characterized work hardening and springback in titanium sheet metal. While unrelated to microplastics, research on mechanical behavior of metals is relevant to understanding how metal and polymer particles are generated during manufacturing and wear.
Evaluation of Waste-Plastic Pyrolysis Oil as a Potential Feedstock for Lubricant Base Oil Production via Hydroprocessing
Scientists found a way to turn plastic waste into high-quality lubricant oil by heating it up and treating it with special metal catalysts. This process converted over 88% of the waste plastic into useful oil that could replace petroleum-based lubricants. This breakthrough could help reduce plastic pollution while creating valuable products, though more research is needed before it becomes widely available.
On-Road Measurements and Modelling of Disc Brake Temperatures and Brake Wear Particle Number Emissions on a Heavy-Duty Tractor Trailer
Despite its title referencing "plasticity," this paper studies residual stress patterns in 50CrMo4 steel subjected to laser heat treatment — not plastic pollution or microplastics. It examines how tempering transformation affects the internal stresses in metal components and is not relevant to microplastics or human health.
