In this study, the commercial TiO2 nanopowder and micropowder of anatase phase and rutile phase have been characterized by x-ray diffraction (XRD) and transmission electron microscopy (TEM). XRD patterns of nano-TiO2 in rutile and anatase phases exhibit broad peaks whereas both phases of micro-TiO2 demonstrate very sharp peaks. TEM images show that the grain size of TiO2 micropowders and TiO2 n...

Mn-doped nanocrystalline ZnO particles have been successfully synthesized at low temperature (80 ̊C) by the coprecipitation method using zinc sulfatehepta hydrate and NaOH. The structural and magnetic properties have been characterized using X-ray diffraction (XRD), Energy dispersive x-ray, vibrating sample magnetometer and electron spin resonance. XRD measurements revealed that the sample posse...

Undoped Zinc oxide (ZnO) nanoparticles as well as ZnO nanoparticles doped with Magnesium (Mg) were synthesized by wet chemical precipitation method using Zinc acetate and Magnesium acetate in Ethylene glycol and distilled water medium. The prepared nanoparticles were characterized with X-ray diffraction (XRD). The XRD patterns show the pattern of typical ZnO nanoparticles and correspond with st...

A bulk single crystal sample of cadmium telluride (CdTe) was irradiated with a ~3 mJ/cm infrared femtosecond laser and analyzed with time-resolved X-ray diffraction (XRD) performed on an in-air tabletop designed for an extremely short pulsed X-ray source. The integrated intensity of Kα XRD lines from the CdTe (111) plane was decreased by 4%–5% in the time scale of ~200 ps. The changes in integr...

Density, chemical, structural and vibrational studies of GexSb65Se35-x system with 0 ≤ x ≤ 20 produce by melt-quench technique were carried out using Archimedes method, Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD) and Raman spectroscopy. All specimens are polycrystalline in nature as confirmed by XRD pattern. The compositional dependence of the XRD and Raman spectra suggests th...

biological systems provide many examples of specifically tailored, nanostructured molecules with highly optimized properties and characteristics. these biomaterials are composite materials and consist of an inorganic component and a special organic matrix. crystalline bacterial cell surface layers (s-layers( are the outermost cell envelope component of many eubacteria and archaea and are compos...

Molecular beam epitaxy grown InAs/GaSb superlattices, containing InSb-like interfacial layers, were analyzed by a combination of x-ray diffraction XRD and structural refinement. The superlattice refinement from x rays SUPREX method determines with high accuracy the average thicknesses and d spacings of the individual InAs and GaSb layers in addition to standard structural parameters usually obt...

This section contains details regarding the preparation of catalyst and membranes and further details on the experimental setup (including two photographs of the XRD-CT experimental setup), a comment relating to an artefact present within this XRD-CT, normalised summed intensity changes (as a companion to Figure 2), XRD-CT data focusing on the BCFZ membrane, a diffraction pattern to illustrate ...
