Rietveld Structure Refinement of Cu-Trien Exchanged Nontronites [PDF]
Frontiers in Chemistry, 2018 The Rietveld analysis of X-ray powder diffraction patterns is used widely for obtaining the structural information of clay minerals. However, the complex hydration behavior and the variability of interlayer contents are often considered difficult to be ...

Rietveld refinement guidelines [PDF]
Journal of Applied Crystallography, 1999 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. The practical rather than the theoretical aspects of each step in a typical Rietveld refinement are discussed with a view to guiding newcomers in the field ...

Parametric Rietveld refinement [PDF]
Journal of Applied Crystallography, 2007 In this paper the method of parametric Rietveld refinement is described, in which an ensemble of diffraction data collected as a function of time, temperature, pressure or any other variable are fitted to a single evolving structural model. Parametric refinement offers a number of potential benefits over independent or sequential analysis.

Parallel processing for Rietveld refinement [PDF]
Journal of Applied Crystallography, 2002 A method for speeding Rietveld refinements using parallel computing is presented. The method can be applied to most, if not all, Rietveld refinement programs. An example implementation for the Los AlamosGeneral Structure Analysis System(GSAS) package is described.

Co-crystal structures of furosemide:urea and carbamazepine:indomethacin determined from powder x-ray diffraction data [PDF]
, 2020 Co-crystallization is a promising approach to improving both the solubility and the dissolution rate of active pharmaceutical ingredients. Crystal structure determination from powder diffraction data plays an important role in determining co-crystal ...

Evidence for two spin-glass transitions with magnetoelastic and magnetoelectric couplings in the multiferroic (Bi$_{1-x}$Ba$_x$)(Fe$_{1-x}$Ti$_x$)O$_3$ system [PDF]
, 2018 For disordered Heisenberg systems with small single ion anisotropy, two spin glass transitions below the long range ordered phase transition temperature has been predicted theoretically for compositions close to the percolation threshold.
