The effects of plastic deformation by ball milling on the structure of a partly amorphousAl87Ni8La5alloy were investigated by X-ray diffractometry. Lattice parameter, crystallite size and lattice strain of the fcc-Al precipitates were determined by Rietveld refinement, doubleVoigt approach and Williamson-Hall plots. The changes in lattice parameter of fcc-Al nanoprecipitates during ball milling...

The crystal structure of an oscillatory zoned erythrite sample from Aghbar mine, Bou Azzer, Morocco, was refined using synchrotron high-resolution powder X-ray diffraction (HRPXRD) data, Rietveld refinement, space group C2/m, and Z = 2. The crystal contains two sets of oscillatory zones that appear to have developed during epitaxial growth. The unit-cell parameters obtained are a = 10.24799(3) ...

heat treated In2O3 nanowalls using FULLPROF. [1] A Thompson-Cox-Hastings pseudo-Voigt profile function was used to simulate the In2O3 as well as the SnO2 phase resulting from the FTO substrate. Preferred orientation has been taken into account in all refinements. The final Rietveld refinement plots are shown in Figure 2c-d in the main text. The FTO substrate in both patterns showed a strong pre...

Bioapatite, the main constituent of mineralized tissue in mammalian bones, is a calcium-phosphate-based mineral that is similar in structure and composition to hydroxyapatite. In this work, the crystallographic structure of bioapatite in human fetuses was investigated by synchrotron radiation x-ray diffraction (XRD) and microdiffraction ( micro -XRD) techniques. Rietveld refinement analyses of ...

Neutron diffraction study of nanostructured magnetite was performed at room temperature. The actual grain-size was determined from evaluation of X-ray diffraction profiles by the modified Williamson-Hall plot. The atomic structure parameters and the sublattice magnetic moments were determined using the Rietveld refinement of the neutron diffraction spectra. The sublattice magnetization at the o...
