Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Calculation of Fluorescence Intensities in Grazing-Emission X-Ray Fluorescence Spectrometry

Analytical Sciences, 1995
The fluorescence intensities in grazing-emission X-ray fluorescence spectrometry were calculated by applying asymptotics to the Fourier integrals resulting from the Helmholtz equation. This approach has led to a straightforward interpretation of the interference of fluorescence radiation from layered materials.
