Techniques," SAE Int.
In this beginning undergraduate textbook on the principles of X-ray diffraction
and its application in analyzing crystalline structures, Lee assumes no background in crystallography or optics and only an elementary knowledge of mathematics.
12 February 2016 - US-based biotechnology product development company Thermo Fisher Scientific has acquired INEL Inc., a provider of real-time X-ray diffraction
systems based in Artenay, France, the company said.
"The work done by the team at Lawrence Berkeley National Lab has resulted in a great tool for monitoring X-ray diffraction
experiments," says Robert Newman, CEO of MiTeGen.
The company is engaged in X-ray spectrometry, X-ray diffraction
, non-destructive testing, X-ray microscopy, Raman spectroscopy and optics, as well as small molecule and protein crystallography and semiconductor metrology.
After machining the samples, residual stresses on one set of uncracked deposited tracks (S1-S3) were measured using X-ray diffraction
technique, based on sin 2y method  which uses the planes of crystal lattice as an atomic scale "strain gauge." X-ray residual stress analysis is based on the angular shift of diffraction lines due to stresses .
It was found that X-ray diffraction
patterns of samples of vanadium-containing gel, taken within the range from 5 to 25 minutes, are identical.
The results obtained "provide refined and in some cases new identifications of the minerals in this first X-ray diffraction
analysis on Mars," a NASA researcher said.
Key words: Engineering geology, X-Ray diffraction
