摘要:Abstract(#br)Elemental analysis of liquid matrix using X-ray fluorescence (XRF) spectrometry suffers some technical drawbacks involving significant errors in obtained data. The main problem of liquid samples include a high X-ray scatter background which often leads to too low sig...

摘要:... X-ray fluorescence computed tomography (XFCT) is considered a promising non-invasive imaging technique to obtain the bio-distribution of nanoparticles which include high-Z elements (e.g., gadolinium (Gd) or gold (Au)). In the present work, a set of experiments with quantitati...

摘要:Abstract(#br)Synchrotron X-ray fluorescence analyses of crystal and amorphous clinopyroxene were compared. The results showed that using the synchrotron X-ray as a source of energy, the diffraction X-ray of crystal materials will seriously affect the X-ray fluorescence analysis. ...

摘要:Low energy X-ray fluorescence (XRF) and soft X-ray absorption (XAS) microspectroscopies at high space-resolution are employed for the investigation of the coelectrodeposition of composites consisting of a polypyrrole(PPy)-matrix and Mn-based ternary dispersoids, that have be...

摘要:... Mobile energy-dispersive X-ray fluorescence (EDXRF) spectroscopy of a dentition is a method of identification that has the potential to be easier and cheaper than CT, although it cannot be used with every dentition. In challenging cases, combining both techniques could fac...

摘要:... Total reflection X-ray fluorescence (TXRF) and energy dispersive X-ray fluorescence (EDXRF) with improved features, e.g. application of filters, secondary target and instrumental geometry require very small amount of sample and thus can be suitably used for the characterizati...

摘要:Abstract(#br)We propose a non-invasive approach for the study of illuminated manuscripts based on the combination of near-infrared reflectance imaging, X-ray fluorescence mapping, and Raman spectroscopy. Taking advantage of the different absorption coefficient of the characterist...
