ClearVariety of scaling behaviors in nanocrystalline plasticity
This is a materials science study examining the variety of scaling behaviors observed in nanocrystalline plasticity, exploring how grain size affects deformation mechanisms in metals. It is not related to environmental microplastics.
Role of Grain Boundary Sliding in Texture Evolution for Nanoplasticity
This materials science paper presents a crystal plasticity model for how grain boundary sliding affects texture evolution in nanocrystalline metals under large deformation. It is a technical metallurgy study with no connection to microplastics or environmental health.
Avalanche statistics and the intermittent-to-smooth transition in microplasticity
This physics study found that at very small scales, crystal plasticity transitions from intermittent to smooth flow as deformation rate increases. It is a materials science paper on metal deformation mechanics, unrelated to environmental microplastics.
Discontinuous yielding of pristine micro-crystals
This theoretical physics paper develops a model for crystal deformation in dislocation-free materials. While not related to environmental science or microplastics, the work contributes to materials science research on plastic deformation at the microscale.
Nontrivial scaling exponents of dislocation avalanches in microplasticity
This physics study analyzed the statistical patterns of small-scale deformation events (dislocation avalanches) in metals to test theoretical models of material plasticity. The research is in materials physics and is not related to environmental microplastics.
Probing Microplasticity in Small-Scale FCC Crystals via Dynamic Mechanical Analysis
This study used dynamic mechanical analysis to study pre-yield dislocation activity — tiny structural movements — in small-scale face-centered cubic metal crystals. It is a materials science paper on nanoscale metal plasticity with no connection to environmental microplastics.
Non-universal behavior of intermittent flow in microplasticity
Microcompression experiments on single-crystal metals revealed that dislocation avalanche behavior during plastic deformation is not universal as some theories predicted, but instead depends significantly on crystal structure, loading orientation, and drive rate. The power-law scaling exponents varied across conditions, spanning values predicted by competing theoretical models.
Fluctuations in crystalline plasticity
This theoretical physics paper reviews the statistical patterns of intermittent plastic deformation events—called dislocation avalanches—in crystalline metals at the micro- and nanoscale. The term 'microplastic' here refers to a materials science concept about deformation behavior, not environmental plastic particles.
From Micro‐ to Macroplasticity
This materials science perspective discusses the transition from microplastic deformation (below the yield stress) to macroplastic deformation in nanocrystalline metals, noting that the traditional 0.2% yield stress definition does not accurately capture when bulk plastic flow begins. This is a materials physics study on metal deformation behavior with no relevance to environmental microplastics.
Microplasticity Detected by an Acoustic Technique
This materials science paper describes an acoustic technique that detects microplastic deformation events — tiny slip occurrences within metal crystals during loading — by monitoring longitudinal oscillations. 'Microplasticity' here refers to microscale plastic deformation in crystalline materials and is unrelated to environmental plastic pollution.
Room temperature deformation of 6H–SiC single crystals investigated by micropillar compression
Researchers studied the deformation of silicon carbide crystals at the microscale, finding that both slip and fracture occur at room temperature under very high stress. This materials science research is unrelated to microplastics but contributes to understanding how materials fragment under mechanical stress.
Viscosity and transport in a model fragile metallic glass
This paper uses the term 'microplasticity' in the context of metallic glass physics, describing how thermally activated atomic movements drive deformation in amorphous metals at the microscale. This is a materials physics paper unrelated to environmental microplastic pollution.

This paper reviews numerical models of deformation-induced surface phenomena in polycrystalline metals at the micro- and mesoscale. The research is focused on materials science and has limited direct relevance to microplastic pollution.
Electron microscope investigation of the microplastic deformation mechanisms of silicon by indentation
This materials science paper uses electron microscopy to study dislocation structures and phase transformations in silicon crystals under indentation at various temperatures. The term 'microplastic deformation' refers to small-scale plastic deformation in crystalline silicon and is entirely unrelated to environmental plastic pollution.
