Analysis of the Internal Anatomy of Distal Root Canals of Mandibular Molars: A Micro‐Computed Tomography Study

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Detailed knowledge of the internal anatomy of the root canal system and its variations is essential for selecting appropriate endodontic treatment protocols. Micro‐computed tomography (micro‐CT) allows for nondestructive, high‐resolution three‐dimensional (3D) analysis of extracted teeth, enabling precise evaluation of root canal morphology ...

Characterization of a Portable Computed Tomography System for In Situ Analysis of Wooden Sculptures in Cultural Heritage

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Portable X‐ray computed tomography (portable CT) has become an important tool for the non‐destructive investigation of cultural heritage objects, particularly when in situ analysis is required. This work presents the experimental characterization and application of a transportable cone‐beam CT system designed for the inspection of large and ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Multielemental Analysis in Rice Grains by Total Reflection X‐Ray Fluorescence

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Rice (Oryza sativa) is a staple food cultivated worldwide and represents a significant source of essential nutrients for humans. However, this cereal may also contain potentially toxic elements including chromium, arsenic, and lead typically present at trace concentrations (ng.g−1).

Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.
