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 ...
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 ...
Mineralization of human premolar occlusal fissures. A quantitative histochemical microanalysis.
(Histology and histopathology., 2017)
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 ...
Qualitative microanalysis of calcium local structure in tooth layers by means of micro-RRS
The Resonant inelastic X-ray scattering or resonant Raman scattering is an inelastic process of second order that becomes important when the energy of the excitation radiation is below but close to an absorption edge. In ...
Separate K-line contributions to fluorescence enhancement in electron probe microanalysis
(Elsevier Science, 2013-01)
The behaviour of the fluorescence enhancement correction factor in electron probe microanalysis, as a function of incident electron energy and take-off angle, is assessed for different binary samples in a wide range of ...
Acid-etching effects in hypomineralized amelogenesis imperfecta. A microscopic and microanalytical study.
(Medicina Oral, Patología Oral y Cirugía Bucal., 2017)
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, ...
