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.

Tetraammine(carbonato-κ2O,O′)cobalt(III) nitrate: a powder X-ray diffraction study
Acta Crystallographica Section E, 2013 Practical chemistry courses at universities very frequently propose the synthesis and characterization of [Co(CO3)(NH3)4]NO3, but this goal is never achieved since students only obtain the hemihydrated form.

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 ...
