Fourier modelling of the anisotropic line broadening of X-ray diffraction profiles due to line and plane lattice defects

TL;DR: In this article, a new model of line-profile broadening due to the effect of linear and planar lattice defects has been incorporated into the conventional Rietveld algorithm for the structural refinement and whole-pattern fitting of powder data.

The behavior of mixed-metal oxides: Structural and electronic properties of Ce1-xCaxO2 and Ce1-xCaxO2-x

TL;DR: In this paper, the structural and electronic properties of mixed-metal oxides were studied using first-principles density functional (DF) calculations and XRD results and DF calculations showed that doping with calcium induces relatively minor variations (<0.05 A) in the cell dimensions of ceria.
