NADA is a computer program for the simultaneous refinement of the components of the orientation matrix and the components of up to three modulation vectors by the method of least squares. Using the spatial peak positions and the orientation matrix of the m ...
Microcrystalline hydrogenated silicon films (muc-Si:H) have been deposited by a high current DC plasma in argon-silane-hydrogen mixtures at growth rates up to 10 nm/s and at substrate temperatures below 500 degreesC. Scanning electron microscopy, X-ray dif ...
Single crystals of self-synthesized mordenite−Na were used for incorporation of the cationic dye molecule thionin blue (C12H10N3S+). The planar organic molecule (7.5 × 15 Å), which fits into the large 12-membered ring channel of mordenite, was incorporated ...
Phase transitions in micro-, submicro-, and nanocrystalline NaNbO3 were investigated by temperature-tuning Raman spectroscopy and X-ray powder diffraction method. Three powders with different average particle size showed successive phase transitions within ...
X-ray diffraction (XRD) is a powerful technique for the study of crystalline materials. The technique of Rietveld refinement now enables the amounts of different phases in anhydrous cementitious materials to be determined to a good degree of precision. Thi ...
Lutetium and yttrium oxides are promising scintillating materials suitable for use in medical planar X-ray imaging and mammography. In this paper the procedure for preparation of europium doped mixed lutetium-yttrium oxide nanopowders using polymer complex ...
Three new bimetallic framework compounds, namely, (([Cd3(tn)4][Co(CN)6]2)·5H2O)∞ (1), ([Cd(tn)]3[Cr(CN)6]2)∞ (2), and ([Cu2(tn)2][Ru(CN)6]·4H2O)∞ (3), have been prepared in a very simple manner from the ligand 1,3-diaminopropane (tn), the hexacyanometalate ...
e report an investigation concerning the influence of ion bombardment on the nanostructure and physical properties of Zr–Si–N nanocomposite thin films. The films were deposited by reactive magnetron sputtering from individual Zr and Si targets. The Si cont ...
LaCoO3 perovskite was prepared at 700degreesC using citrate precursors. The product was then characterized with X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS). The powder XRD pattern indicates rhomboliedral (R (3) over barc) or its monocli ...
The comparable order of magnitude between interatomic distances in a crystal and the wavelength of X-rays make X-ray crystallography the ideal analytical tool to gain insight into the structure of crystalline material, including biomolecules. Nevertheless, ...
