Full-profile analysis of microdensitometer-measured Guinier–Hägg X-ray powder film data (strictly monochromatized Cu Kα1 radiation) [see Malmros & Thomas (1977). J. Appl. Cryst. 10, 7–11] is here extended to treat a multicomponent system where two of the components are refinable. The method is demonstrated for the cas…

M. Wilkens1979-02-01Journal of Applied Crystallography
The paper deals with a theoretical investigation of the shapes of the X-ray diffraction lines of crystals containing periodically distributed small-angle boundaries (SAB) of pure tilt character. The Fourier transforms of the diffraction lines are computed and subsequently subjected to a Warren–Averbach (WA) analysis.…

Two-dimensional X-ray diffraction patterns may be recorded quantitatively by means of X-ray-to-electron converters which are scanned in a television-type raster scan. Detectors of this type are capable of operating over the whole range of counting rates from very low to higher than those with which other types of conv…

A microstructural evaluation was made of experimental non-Ohmic ZnO ceramics by optical, scanning, and transmission electron microscopy complemented with electron beam microprobe and x-ray analyses. Four crystalline phases were identified: a major phase of ZnO grains containing Co and Mn in solid solution and three mi…

Current peaks due to transient SCLC were observed both in high-density polyethylene (HD-PE) and in oxidised HD-PE in the temperature range 50-90 degrees C. From the time at which the current peak occurs, carrier mobilities ranging from 10 -11 to 10 -9 cm 2 V -1 s -1 were obtained. The mobility values obtained agree we…

Single barriers in a ZnO varistor are measured separately. The step voltage at a grain boundary is 3.6 V at 1 μA. No great differences could be found between samples obtained from several suppliers. In a SEM the barriers could be detected by the voltage-contrast method. By using electron-beam-induced currents the spot…

Abstract Poly( p ‐phenylene terephthalamide)(PTTA) films were prepared from sulfuric acid solution with various coagulants. X‐ray diffraction and infrared absorption measurements revealed that the crystal structure of the film coagulated with water showed a new crystal modification II, which was different from the one…

A literature survey was conducted to collect mineralogical data of Canadian soils. In the past 40 years, clay mineralogical data of varying precision have been reported for approximately 1200 samples from more than 380 pedons. Based on the data, (1) the distribution of clay minerals was examined physiographically, (2)…

The complex index of refraction N=n−ik for amorphous SiO2 is derived in the energy range 0.03–1.0 eV by Kramers-Kronig analysis of reflectance data. The results are used to compute the transmission, reflectance, and absorptivity of thin layers of SiO2 on Si substrates in the vicinity of the 0.14-eV (9 μ) lattice absor…

Abstract— Methyl viologen was reduced by EDTA and other organic compounds when aqueous solutions of these compounds were irradiated near 440 nm in the presence of catalytic quantities of proflavin. The photoreduced methyl viologen was readily oxidized in the dark by the enzyme hydrogenase or platinum asbestos. When th…

Vibrational spectra and LEED structures of CO on the Ru(001) surface were measured as a function of coverage at 100 K. The LEED patterns indicate that CO occupies a variety of asymmetric sites at high coverage, while the vibrational spectra show a single Ru–C stretching frequency (445 cm−1) and a single C–O stretching…

Existing theories for commensurate-incommensurate transitions in one-dimensionally-modulated systems show that these transitions are continuous and are associated with domainwall formation. We consider the effect of domain-wall crossing in two-dimensionally modulated systems with hexagonal symmetry such as rare-gas la…
