Standard x-ray diffraction powder patterns :

Abstract

During preparation of the book, some errors were found and corrected on the card images. A list of them is available on request. The corrections below are in addition to those included on the card images. Monograph 25Sec. 14, p. The experimental x-ray powder diffraction patterns were obtained with an x-ray diffractometer.All d-values were assigned Miller indices determined by comparison with computed interplanar spacings consistent with space group extinctions. The densities and lattice constants were calculated and the refractive indices were measured whenever possible. The calculated x-ray powder diffraction patterns were computed from published crystal structure data.Both peak height and integrated intensities are reported for the calculated patterns.

Synthesis and spectroscopic identification of nickel and cobalt layered hydroxides and hydroxynitrates

“…The patterns of β-Ni(OH) 2 and β-Co(OH) 2 shown in Fig. 2(a-i) and (a-ii) match to reported data for the nickel hydroxide mineral theophrastite (ICDD PDF 14-117) 47 and cobalt hydroxide (ICDD PDF 30-0443) 48 indicating the brucite-type structure formed with a = 3 Å and c = 4.5 Å in space group P3 ˉm1. The 001 reflections would be broadened if the layer stacking was disordered, but experimentally they were observed to be as sharp as the other reflections, implying the structures are crystalline.…”

Sub-nanograin metal based high efficiency multilayer reflective optics for high energies

“…In Table 2 , the observed peak positions in MLs are within 17.98–18.10°, which are lower than the stress free bulk W (110) value (2 θ = 18.44° at E = 17.295 keV). 44 Further, in-plane FWHM is smaller than out-of-plane. Importantly, the approximate average crystallite sizes in both in-plane and out-of-plane are in the range of 0.50–0.67 nm, as obtained using the Scherrer equation.…”

Infrared spectra of the ammonium ion in crystals. Part XIII. Crystal structure of (NH4)2[AlF5(H2O)] and NH3D+ probe-ion spectra in (NH4)2[AlF5(H2O)], NH4AlF4, and (NH4)3ZnCl5, with remarks on structural filiation of AMF4 fluorides

“…13). (NH4)3ZnC15 was prepared by slow evaporation over CaCI2, at room temperature, of a 3/1 molar aqueous solution of NH4CI and ZnC1' (13,17). It was deuterated by repeating the preparation with H20-D,O solutions.…”
