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

Spectromicroscopy Analysis of Chicken Egg Shells
X-Ray Spectrometry, EarlyView.ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization
X-Ray Spectrometry, EarlyView.ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Archaeometry, EarlyView.Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...
