Rietveld Refinement Analysis of Lampung Natural Zeolite Catalyst Impregnated Fe with Diffraction Method Using MAUD Software [PDF]
This research characterizes the space group and R-phase crystal structure using the XRD method and Rietveld refinement. Rietveld improvements using the Material Analysis Using Diffraction (MAUD) software are acceptable if the Rwp < 15% and Sig < 2%. MAUD

Study of Constitutive Behavior of Ferroelectrics via Self-Consistent Modeling and Neutron Diffraction [PDF]
The central goal of this study is to develop a reliable self-consistent model to describe the constitutive behavior of polycrystalline ferroelectrics and to predict their lattice strain and texture evolution. Starting with the model developed by Huber et
