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 ...

Acemetacin cocrystal structures by powder X-ray diffraction

IUCrJ, 2017
Cocrystals of acemetacin drug (ACM) with nicotinamide (NAM), p-aminobenzoic acid (PABA), valerolactam (VLM) and 2-pyridone (2HP) were prepared by melt crystallization and their X-ray crystal structures determined by high-resolution powder X-ray ...

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 ...
