TL;DR: A set of general guidelines for structure refinement using the Rietveld (whole profile) method has been formulated by the International Union of Crystallography Commission on Powder Diffraction.

TL;DR: In this article, the DICVOL04 algorithm was extended to include a tolerance to the presence of impurity (or inaccurately measured) diffraction lines, a refinement of the zero-point position, a reviewing of all input lines from the solution found from, generally, the first 20 lines, and a cell analysis, based on the concept of the reduced cell, to identify equivalent monoclinic and triclinic solutions.

TL;DR: The results of both a line-broadening study on a ceria sample and a size-strain round robin on diffraction line broadening methods, which was sponsored by the Commission on Powder Diffraction of the International Union of Crystallography, are presented in this paper.

TL;DR: In this article, a powder pattern can be simulated for a given distribution of sizes, if it is assumed that on average the crystallites have a regular shape, and this can then be compared with experimental data to give refined parameters defining the distribution.

TL;DR: In this article, a task group of the JCPDS-International Center for Diffraction Data (ICDD) was established with the charge of investigating the use of silver behenate, CH 3 (CH 2 ) 20 COO·Ag, as a possible low-angle calibration standard for powder diffraction applications.
