the study describes the synthesis and characterization of zinc(ii) minoxidil nanocomposite (1). the reaction between zinc(ii) acetate, minoxidil, {c9h15n5o=minoxidil=(2,4-diamino-6-piperidine-1-yl) pyrimidine n-oxide)} as a ligand and ki as bridging agent, in methanol at 60°c leads to the formation of nano-sized zn(ii) minoxidil nanocomposite, 1. characterization of (1) was carried out by eleme...

The Advanced Photon Source (APS) at Argonne National Laboratory was used to obtain real-time, high-resolution x-ray diffraction measurements to determine the microscopic response of shock-compressed single crystals. Disk shaped samples were subjected to plane shock wave compression by impacting them with half-inch diameter, flat-faced projectiles. The projectiles were accelerated to velocities ...

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...

X-ray diffraction observation of metal fracture provides fracture analysis with useful information on the mechanics and mechanical conditions of fracturing. This method is called “X-ray Fractography” and has been developed especially in Japan as a new engineering tool for fracture analysis[1-3]. X-ray fractographic technique was applied to fracture surface of dental material. The relationship b...

A surface layer ("skin") different from the bulk was found in single crystals of BiFeO(3). Impedance analysis and grazing incidence x-ray diffraction reveal a phase transition at T(*)∼275±5 °C that is confined within the surface of BiFeO(3). X-ray photoelectron spectroscopy and refraction-corrected x-ray diffraction as a function of incidence angle and photon wavelength indicate a reduced elect...

A high-intensity grazing-incidence X-ray diffractometer system, which uses a parabolic graded multilayer mirror and an 18-kW rotating-anode generator, has recently been developed for the structural characterization of surfaces and thin film~. Its goniometer has two in-plane tp/20 x axes and two conventional m¢20 axes for measurements of in-plane and out-of-plane diffraction, respectively. The d...

where the peak shapes were described by a pseudo-Voigt function and the background was modeled with an 6-term polynomial. Additionally, the PXRD patterns obtained at room temperature and 100 K were analyzed by Le Bail refinement using the GSAS and EXPGUI software, 2,3 where the peak shapes were described by a pseudo-Voigt function (CW profile function 3) and the background was modeled with an 4...
