Features of formation of composite ceramics from SiC-Si-Mo at high pressure [PDF]

open access: yesScience of Sintering, 2009
SiC-based composite ceramics were investigated by X-ray diffraction, electron microscopy and electron-probe X-ray microanalysis. It is established that, depending on the composition of the initial powder mixtures, at T = 1500-1800°C and P = 4 GPa ...

Phase Equilibria in the Ni-V-Ta Ternary System

open access: yesMetals, 2018
Two isothermal sections of the Ni-V-Ta ternary system at 1200 °C and 1000 °C have been experimentally established using X-ray diffraction, electron probe microanalysis, energy dispersive spectroscopy, and differential scanning calorimeter with ...

Evaluation of the cell viability of human Wharton's jelly stem cells for use in cell therapy [PDF]

open access: yes, 2012
Human umbilical cord Wharton's jelly stem cells (HWJSCs) are gaining attention as a possible clinical source of mesenchymal stem cells for cell therapy and tissue engineering due to their high accessibility, expansion potential, and plasticity.

Inter-laboratory comparison of a WDS-EDS quantitative X-ray microanalysis of a metallic glass [PDF]

open access: yes, 2014
We conducted an inter-laboratory study of a metallic glass whose main component is nickel. Two determinations of the mass fractions of the different elements present within the sample were asked to the participants: one at an acceleration voltage of 15 ...

High precision measurement of trace F and Cl in olivine by electron probe microanalysis

open access: yesProgress in Earth and Planetary Science, 2023
Fluorine (F) and chlorine (Cl) are important volatiles in olivine and its high-pressure polymorphs, which would significantly affect olivine phase transition, melting temperature, and physical property of the mantle.

Quantitative electron probe microanalysis in the system Fe-Sn-C using the Claisse-Quintin relation [PDF]

open access: yes, 1985
Quantitative interpretation of EPMA measurements was required for the construction of the Fe-Sn-C phase diagram. This involved the conversion of measured x-ray intensities into concentrations, which is difficult for a light element (such as C) being ...

Isomorphic Substitution in Vanadinite [Pb5(VO4)3C1] - Raman Spectroscopic Study [PDF]

open access: yes, 2003
The Raman and infrared spectroscopy of three vanadinite [Pb5(VO4)Cl] specimens from three localities has been studied. Single crystal Raman spectra were obtained and the spectra were found to be both orientation and temperature dependent.

Evaluation of implant calcium-phosphate materials depending on their mineral content

open access: yesБюллетень сибирской медицины, 2012
Biocompatibility of original implant calcium-phosphate materials was evaluated in the experiment on animals. The methods of radiological electron-probe microanalysis (REMA) and light and scan electron microscopy (SEM) were used. Studied materials had the
