Micro-PIXE imaging of the rib bones of rats
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and AtomsThe ribs are bones that constitute the ribcage and consist of three regions: cartilage, costochondral junction with growth plate structures, and hard bone. In this study, frozen sections of rat ribs were prepared, and the distributions of calcium (Ca), phosphorus (P), potassium (K), and sulfur (S) were examined using particle-induced X-ray emission ...

In Vivo Characterization of Magnetic Inclusions in the Subcortex From Nonexponential Transverse Relaxation Decay. [PDF]
NMR BiomedNonexponential transverse relaxation decay allows to characterize the spatial distribution of magnetic material within subcortical grey matter tissue. ABSTRACT According to theoretical studies, MRI signal decay due to transverse relaxation in brain tissue with magnetic inclusions (e.g., blood vessels and iron‐rich cells) is expected to follow a ...

Archaeometric characterization of Byzantine pottery from Păcuiul lui Soare
Heritage Science, 2019 Archaeometric investigations using OM (optical microscopy) and micro-PIXE (particle induced X-ray emission) were performed on 45 ceramic shards unearthed in archaeological excavations at Păcuiul lui Soare (southeastern Romania) and dated to the eleventh ...

Deciphering the preservation of fossil insects: a case study from the Crato Member, Early Cretaceous of Brazil [PDF]
PeerJ, 2016 Exceptionally well-preserved three-dimensional insects with fine details and even labile tissues are ubiquitous in the Crato Member Konservat Lagerstätte (northeastern Brazil). Here we investigate the preservational pathways which yielded such specimens.

Localization of Aluminum in Epidermal Cells of Mature Tea Leaves
Quantum Beam Science, 2019 We have determined the distribution of aluminum in the epidermal cells of mature tea leaves using micro-beam particle-induced X-ray emission. The observed pattern of aluminum distribution in the epidermal cells suggests that aluminum exists in cell walls.
