Simultaneous measurements of X-ray diffraction (XRD) and differential scanning calorimetry (DSC) data under controlled humidity condition: Instrumentation and application to studies on hydration, dehydration, and rehydration processes of pharmaceutical compounds
Autor: A. Kishi, H. Toraya
Publikováno v: Powder Diffraction. 19:31-35
An instrument for the simultaneous measurement of X-ray powder diffraction (XRD) data and differential scanning calorimetry (DSC) data under a controlled humidity condition has been developed in order to achieve a design concept of reliable and simpl

Crystal structure refinements of In x Fe3−x O4(x ≤ 0.3) spinels by the Rietveld method
Autor: H. Okudera, H. Toraya
Publikováno v: Zeitschrift für Kristallographie - Crystalline Materials. 213:461-465
The distribution of In3+ between tetrahedral and octahedral sites and coordinate of oxygen in In x Fe3−x O4 (x = 0, 0.1, 0.2, and 0.3) spinels have been determined on powder samples by the Rietveld method. The weight function with a form wYi = l/Yo

Symmetry Information Inherent in Powder Diffraction Data: α- and β-Quartz as Examples
Autor: H. Tokushima-Houki, K. Ohsumi, M. Ohmasa, H. Toraya
Publikováno v: Journal of Applied Crystallography. 30:254-258
Laue classes of powder diffraction data for tetragonal, hexagonal and cubic crystal families can be derived from interpretation of the concentration of peaks in Patterson functions that are transformed from weighted reciprocal lattices constructed wi

An X-ray Powder Diffraction Study of Sr2LnTaCu2O8, Ln = Nd, Sm, Eu, Gd
Autor: P. Planinić, I. Basic, B. Grzeta, H. Toraya, N. Brničević
Publikováno v: Journal of Applied Crystallography. 29:37-41
A series of oxides of the composition Sr2LnTaCu2O8, Ln = Nd, Sm, Eu, Gd has been prepared and characterized by X-ray powder diffraction. Samples are tetragonal, space group P4/mmm and isostructural with a perovskite-like phase Ba2LaTaCu2O8. The unit-
