Kinetics of variation of electrical resistance and yield strength in technically pure nickel due to loading in the elastic range at 300-77 K [PDF]

, 2010
Results of a study of the variation in yield strength and electrical resistance of technically pure nickel in different initial structural states as a function of the test temperature and applied stress are presented.

Micro-and macro-plastics in marine species from Nordic waters [PDF]

, 2017
This report summarises the knowledge on plastics in Nordic marine species. Nordic biota interacts with plastic pollution, through entanglement and ingestion. Ingestion has been found in many seabirds and also in stranded mammals.

Novel use of field-portable-XRF for the direct analysis of trace elements in marine macroalgae. [PDF]

, 2017
Samples of dried marine macroalgae (Fucus serratus, Palmaria palmata and Ulva lactuca) have been analysed for trace elements by a novel, non-destructive approach involving a Niton field-portable-X-ray fluorescence (FP-XRF) spectrometer configured in a ...

Sample size requirements for riverbank macrolitter characterization

Frontiers in Water, 2023
Anthropogenic litter is omnipresent in terrestrial and freshwater systems, and can have major economic and ecological impacts. Monitoring and modeling of anthropogenic litter comes with large uncertainties due to the wide variety of litter ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

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

Conservation Science and Practice, EarlyView.
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.

Life on bottles: Colonisation of macroplastics by freshwater biota

Science of The Total Environment, 2023
While rivers are known to be the main vectors of plastics to the sea, it seems surprising that studies on interactions (e.g. colonisation/entrapment and drift) between macroplastics and biota continue to remain largely neglected, notwithstanding they represent unexpected threats to freshwater biota and riverine habitats.

Global distribution of potential impact hotspots for marine plastic debris entanglement [PDF]

, 2022
Marine animals have been known to interact with and become entangled in plastic debris for decades. Despite increasing annual input volumes of plastic waste to the natural environment and the threat this constitutes to marine biodiversity, impacts of ...

Rivers as Plastic Reservoirs

Frontiers in Water, 2022
Land-based plastic waste, carried to the sea through rivers, is considered a main source of marine plastic pollution. However, most plastics that leak into the environment never make it into the ocean.
