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.

Scanning ultrafast electron microscopy [PDF]

open access: yes, 2010
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200

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 ...

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

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.
