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.

Subtracting Interferences in X‐Ray Spectra Obtained With Grating Spectrometers

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Higher order diffraction from surface contamination poses a major challenge for soft x‐ray spectral analysis using reflection zone plate spectrometers in electron probe microanalysis. We developed two correction methods applied to the Al L2,3 and Zn M2,3 emissions in AlZn60 alloy spectra: sequential overlay and subtraction of C Kα and O Kα ...

Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

open access: yesHigh Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

In vitro and in vivo metabolism profiles of cathinone and pseudoephedrine: Discrimination between khat and pseudoephedrine uses

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract In the present study, the metabolism of khat (Catha edulis) and pseudoephedrine was compared with the aim of identifying objective criteria that could be used to discriminate between them for forensic and doping‐control purposes. An in vitro study using human liver microsomes and an in vivo study using rat urine were performed under harmonized
