XAHRM‐Lab First Results and πXRF First View of UFe4Al8 and UFe10Si2

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Following the installation of the Laboratory for the Characterization and Speciation of Aerosols (LCEA) in 2008, and the confirmation of High Resolution Energy Dispersive Spectrometry (HiREDS) as a much promising development for X‐ray Emission Spectrometry in general and Particle Induced X‐ray Emission (PIXE) in particular, the installation of

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 ...

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 ...

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.
