Structural and elemental X-ray microanalysis with synchrotron radiation in confocal geometry
(Elsevier Science, 2014-01)
A spectrometer for 3D structural and multielemental X-ray microanalysis with synchrotron radiation is presented in this work. It is based on the combination of the energy dispersive X-ray fluorescence and diffraction with ...
Ultrastructure and X-ray microanalysis of Euglena gracilis (Euglenophyta) under chromium stress
(Int Phycological Soc, 2007-05)
The effect of chromium on the biology of Euglena gracilis was studied. The ultrastructural modifications caused by this metal and its location within the cell were analyzed by TEM and EDXA, respectively. The effects of ...
Standardless quantification methods in electron probe microanalysis
(Pergamon-Elsevier Science Ltd., 2014-11)
The elemental composition of a solid sample can be determined by electron probe microanalysis with or without the use of standards. The standardless algorithms are quite faster than the methods that require standards; they ...
Optimization of parameters in electron probe microanalysis
(John Wiley & Sons Ltd, 2001-09)
A method for the refinement of atomic and experimental parameters applicable to several spectroscopic techniques is presented. This kind of procedure, previously used in x-ray diffraction, is shown to be a powerful tool ...
Calibration method for confocal X-ray microanalysis with polychromatic excitation
(Hindawi Publishing Corporation, 2015-01)
To apply the fundamental parameters method at the confocal setup the knowledge of the sensitivity of the spectrometer is required which depends on the characteristics of two X-ray lenses: one in the excitation channel and ...
Chemical characterization of a high nitrogen stainless steel by optimized electron probe microanalysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The distribution of Cr and N in a high-temperature gas-nitrided stainless steel was measured by using a scanning electron microscope-coupled wavelength-dispersive X-ray spectrometer and the results were related to the ...
Optimization of K-shell intensity ratios in electron probe microanalysis
(John Wiley & Sons Ltd, 2002-03)
A method for refinement of atomic and experimental parameters was applied to the optimization of K-shell intensity ratios in electron probe microanalysis (EPMA). This kind of procedure, previously used in x-ray diffraction, ...
Silicon distribution and accumulation in shoot tissue of the tropical forage grass Brachiaria brizantha
(SPRINGER, 2010)
Silicon (Si) accumulation in organs and cells is one of the most prominent characteristics of plants of the family Poaceae. Many species from this family are used as forage plants for animal feeding. The present study ...
