Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.

A Multi‐Analytical Campaign on Reused Medieval Musical Parchment From the Archivio di Stato di Siena (Italy)

X-Ray Spectrometry, EarlyView.
ABSTRACT In this study, a non‐invasive, multi‐analytical approach combining hypercolorimetric multispectral imaging (HMI), stereomicroscopy, X‐ray fluorescence (XRF) spectroscopy, principal component analysis (PCA) and X‐ray radiography (RX) is used to investigate three reused musical parchment fragments dating from the late 14th or early 15th century ...

PolarEyes with enhanced digital imaging, a high‐throughput solution for locating and grading crystals

Journal of Applied Crystallography, EarlyView.
An open‐source program for the calculation and visualization of polarization‐derived properties of crystalline material is described, alongside the integration of a polarizing image sensor into a home‐built high‐throughput imaging setup.The long‐range internal order of crystals enables them to exhibit a well known and long‐exploited phenomenon ...

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Investigating the Dietary, Economic, and Social Practices of a Neolithic Funnel Beaker Community in Wanna, Germany, Through Raw Material and Organic Residue Analyses of Pottery

Archaeometry, EarlyView.
ABSTRACT This study details the analysis of an assemblage of Funnel Beaker pottery from Wanna in Northern Germany investigated using petrographic, geochemical, and organic residue analyses. The analyses revealed specialized production of pottery vessels for funerary contexts, but that domestic and funerary pottery were used intensively to process ...

Late Iron Age and Early Roman Brooches From the Lower Rhine Area: Provenance of the Metal Supply Traced Through Lead Isotopes

Archaeometry, EarlyView.
ABSTRACT Geochemical analysis of five brooch types from the Lower Rhine area dated to the last century bc and first century ad is used to constrain resource use, exchange and mobility. Lead isotope ratios demonstrate an Iberian provenance for copper in bronze Late Iron Age brooches.
