Spectrochemical analysis of dental calculus by synchrotron radiation X-ray fluorescence.
This work presents elemental composition studies of human dental calculus by X-ray fluorescence analysis using synchrotron radiation. The intrinsic characteristics of synchrotron light allow for a quantitative analysis of major, minor, and trace elements of very small samples in a single measurement. At present, several theories of calculus formation exist, but none of them can describe complet...
متن کاملSpectrochemical Analysis of Inorganic Elements in Bacteria.
Rouf, M. A. (Washington State University, Pullman). Spectrochemical analysis of inorganic elements in bacteria. J. Bacteriol. 88:1545-1549. 1964.-Quantitative spectrochemical analyses of inorganic elements in the vegetative cells of Escherichia coli, Sphaerotilus natans, Micrococcus roseus, Bacillus cereus, and the spores of B. cereus were made. The following elements were found to be present i...

are needed. Since the analysis depth depends on the accelerating voltage of the electron beam, the application of low accelerating voltages limits the characteristic-X-ray generation region to a minute region near the specimen surface. However, the energies of the X-rays are less than those of the accelerated electrons; this causes a new problem: the use of analytical X-ray lines is limited. Th...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملX-ray peak broadening analysis in LaMnO3+δ nano-particles with rhombohedral crystal structure
In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...
