X-Ray Fluorescence Ionomics of Herbarium Collections
Scientific Reports, 2019 Global herbaria are the greatest repositories of information on the plant kingdom. Discoveries of trace element hyperaccumulator plants have historically required time-consuming destructive chemical analysis of fragments from herbarium specimens, which ...

X-ray fluorescence spectroscopy from ions at charged vapor/water interfaces [PDF]
J. Appl. Phys. 105 084911 (2009), 2009 X-ray fluorescence spectra from monovalent ions (Cs+) that accumulate from dilute solutions to form an ion-rich layer near a charged Langmuir monolayer are presented. For the salt solution without the monolayer, the fluorescence signals below the critical angle are significantly lower than the detection sensitivity and only above the critical angle ...

X-Ray Luminescence and X-Ray Fluorescence Computed Tomography: New Molecular Imaging Modalities
IEEE Access, 2014 X-ray luminescence and X-ray fluorescence computed tomography (CT) are two emerging technologies in X-ray imaging that provide functional and molecular imaging capability. Both emission-type tomographic imaging modalities use external X-rays to stimulate

X-ray fluorescence from the inner disc in Cygnus X-1
, 1989 Les spectres RX de nombreuses sources de trous noirs en accretion suggerent la presence de matiere relativement froide entouree d'un plasma emetteur de RX dur. Les raies fluorescentes du fer sont produites par l'irradiation RX du gaz froid. On montre que

Experimental determination of tantalum L-shell fluorescence yields and Coster-Kronig transition probabilities [PDF]
arXiv, 2022 Using radiometrically calibrated instrumentation of Physikalisch-Technische Bundesanstalt, the L-shell fluorescence yields and Coster-Kronig factors of tantalum (including the uncertainty budget) were experimentally determined based on transmission and X-ray fluorescence experiments.
