Application of X-ray Powder Diffraction Method in Identification and Classification of Leptite
Yankuang ceshi, 2020 BACKGROUND The identification of leptite is usually based on microscopic identification technology, but it is very difficult to distinguish tiny feldspar, quartz, and layered silicate minerals such as chlorite, montmorillonite and mica using a microscope.

Nanocrystalline materials studied by powder diffraction line profile analysis [PDF]
, 2007 X-ray powder diffraction is a powerful tool for characterising the microstructure of crystalline materials in terms of size and strain. It is widely applied for nanocrystalline materials, especially since other methods, in particular electron microscopy ...

Sub-nanosecond X-ray powder diffraction
Journal of Applied Crystallography, 1990 The X-rays emitted from a laser-produced plasma have been used to obtain powder diffraction patterns with exposures of less than a nanosecond. The X-rays were produced by focusing approximately 50 J of 0.53 μm laser light in a 600 ps (FWHM) pulse to a tight (~100 μm diameter) spot on a solid titanium target.

X-ray characterization by energy-resolved powder diffraction
Physical Review Accelerators and Beams, 2016 A method for single-shot, nondestructive characterization of broadband x-ray beams, based on energy-resolved powder diffraction, is described. Monte-Carlo simulations are used to simulate data for x-ray beams in the keV range with parameters similar to ...
