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

X-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

X-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 ...

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

X-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).

Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...
