ClearWear of ceramic-based dental materials
Researchers compared wear rates and failure mechanisms of several ceramic-based dental materials using a laboratory test simulating chewing contact, finding that zirconia showed the lowest wear and lithium disilicate the highest, with microcracking and microplasticity (small-scale plastic deformation) identified as the key material-removal mechanisms.
Finite Element Analysis and Fatigue Test of INTEGRA Dental Implant System
Researchers conducted finite element analysis and fatigue testing on a dental implant system to evaluate its structural integrity under repeated loading. The study identified potential sites where fatigue cracks could initiate and validated these predictions with physical testing. The findings contributed to the certification process for the dental implant product under European standards.
Fatigue of Yttria‐Stabilized Zirconia: II, Crack Propagation, Fatigue Striations, and Short‐Crack Behavior
This materials science study examines fatigue crack propagation in yttria-stabilized zirconia ceramic, establishing a growth law based on stress intensity factors to predict fatigue lifetime. The term 'microplastic' in this paper refers to microscale plastic deformation in ceramics and is unrelated to environmental plastic pollution.
Comparative analysis of self‐cure and dual cure‐dental composites on their physico‐mechanical behaviour
This paper is not about microplastic pollution. It compares the physical and mechanical properties of self-cure and dual-cure dental composite materials, examining how filler content, resin monomers, and particle size affect hardness, strength, fracture toughness, and degradation of dental restorations.
Zirconia–Alumina Composites Obtained by Centrifugal Slip Casting as Attractive Sustainable Material for Application in Construction
Researchers developed zirconia-alumina ceramic composite tubes using a centrifugal casting method, testing their material properties for industrial applications. This ceramic materials study is unrelated to microplastic environmental research.
The Effect of Halloysite Nanotubes and Mult Wall Carbon Nanotubes on the Mechanical Properties of Poly (Methyl Methacrylate) Denture Base Nanocomposites
Researchers tested how adding halloysite nanotubes and carbon nanotubes improves the mechanical strength and fracture resistance of PMMA denture base plastic. Better understanding how nanomaterials reinforce polymers could help develop more durable medical plastics that shed fewer microplastic particles during use.
Brittle materials at high-loading rates: an open area of research
This paper reviews how brittle materials like ceramics, rocks, and concrete behave when subjected to high-speed impacts and explosive loading, identifying knowledge gaps in understanding their fracture behavior. This materials science study is focused on engineering and defense applications and has no direct relevance to microplastics research.
A model for predicting wear rates in tooth enamel
Researchers developed a theoretical model for predicting tooth enamel wear rates based on the mechanics of micro-scale contact events with sharp particles, validating it against experimental data and showing that sharp, hard particulates in food — rather than overall bite force — govern the transition between mild and severe enamel wear.
Mechanics of microwear traces in tooth enamel
Researchers modeled microwear traces in tooth enamel using indentation mechanics, showing that pits and scratches are produced at forces well below normal biting loads and that the transition from mild plastic deformation to microcracking depends on particulate sharpness and angularity in food — with particular relevance to diet evolution in hominins.
From ultra to nanofiltration: A review on the fabrication of ZrO2 membranes
Researchers reviewed advances in manufacturing zirconia (ZrO2) ceramic membranes used to filter water and industrial fluids, highlighting that their superior chemical resistance, low fouling, and long lifespan make them attractive for water treatment and food processing, though achieving very small pore sizes for nanofiltration remains challenging.
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.
Vat Photopolymerization of Additively Manufactured Zirconia Ceramic Structures from Slurries of Surface Functionalized Particles: A Critical Review
This review critically examines vat photopolymerization techniques for additively manufacturing zirconia ceramic structures from slurries of surface-functionalized particles, focusing on aerospace, biomedical, and energy applications. The authors analyzed challenges in overcoming ceramic brittleness and the high cost of traditional mold-based processing that limit adoption of complex zirconia components.
Effects of Grain Size and Humidity on Fretting Wear in Fine‐Grained Alumina, Al 2 O 3 /TiC, and Zirconia
This tribology study examined how grain size and humidity affect wear in ceramic materials (alumina and zirconia) under fretting conditions, finding that smaller grain sizes reduce wear through microplastic deformation of grain boundaries. This is a ceramics engineering study where 'microplastic deformation' refers to sub-yield material behavior, not environmental plastic particles.
