In the present work, we report a suitable approach for the preparation of BaTiO3 nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffra...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

A generalized dynamical theory has been developed that extends previous models of x-ray diffraction from crystals and multilayers with vertical strains to the cases of grazing incidence and/or exit below the critical angle for total specular reflection. This provides a common description for extremely asymmetric diffraction, surface ~‘‘grazing-incidence’’!, and grazing Bragg-Laue diffraction, t...

1. Background Currently, grand-scale synchrotron radiation facilities, where high-quality X-ray sources are available in wide energy ranges from the softto hardX-ray regions, have significantly advanced the performance characteristics of analytical technologies using the fluorescence, absorption and diffraction effects of X-rays in various materials. The application of X-ray microscopy with the...

In this study, X-ray fractography’)-‘) technique was applied to the (GZ+~) dual phase stainless steel. Effect of the rolling direction on fatigue properties was discussed. Residual stress near the surface was measured by using X-ray diffraction method to the depth direction. Relations between X-ray parameter and fracture mechanics parameter were examined. As the result, distribution of the phas...

in this study, the tio2 nanorods were synthesized from p25 tio2 nanoparticles by hydrothermal method in 10 m naoh solution. the effects of annealing temperatures on produced nanorods were investigated  by scanning  electron microscopy (sem) x-ray diffraction (xrd) and photoluminescence (pl) spectroscopy. diameter growth and  changes  of  surface  oxygen  defects of  synthesized nanorods are stu...

generally arranged at a distance of 0.1 nm to 0.5 nm from one another. When such a substance is irradiated with X-rays having a wavelength roughly equivalent to the interatomic or intermolecular distance, the Xray diffraction phenomenon will take place. X-ray diffraction is widely used in the semiconductor field because it is nondestructive and yields crystal structure information relatively ea...
