Oxygen vacancy (VO) strongly affects the properties of oxides. In this study, we used X-ray diffraction (XRD) to study changes in the VO concentration as a function of the Co-doping level of ZnO. Rietveld refinement yielded a different result from that determined via X-ray photoelectron spectroscopy (XPS), but additional maximum entropy method (MEM) analysis led it to compensate for the differe...

cuins2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  in  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. the effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  the nanostructures  were  characterized  by  means  of  ...

in the current paper,nanostructured nickel oxide (nio) were synthesized by co-precipitation method using nickel(ii) chloride hexahydrate (nicl2.6h2o) and sodium hydroxide (naoh) as starting material. structural, optical and magnetic properties of nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), atomic force microscope (afm), uv–vis absorption; fo...

the nanocrystallization of co67fe4cr7si8b14 amorphous ribbons which prepared by planar flow melt spinning process (pfms) was investigated. crystallization of the ribbons was studied by differential thermal analysis (dta), x-ray diffraction (xrd) and transmission electron microscopy (tem). the dta result of amorphous ribbon at heating rate of 10˚c/min showedoccurrence of phase transitions in two...

our aim in this work is the synthesis and study optical and structural properties of gold nanoparticles.gold (iii) chloride trihydratewas taken as metal precursor, ascorbic acid at the presence of an appropriate amount of naoh as reducing agent and polyvinylpyrrolidonek-30 (pvp k-30) as a stabilizing and capping agent. the reaction was performed in high-speed stirring rate at room temperature.s...

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 ...

A method of synovial fluid preparation giving optimal hydroxyapatite detection as well as definitions of the threshold masses of hydroxyapatite in viscous synovial fluid detectable by x ray diffraction and scanning electron microscopy with energy dispersive analysis is reported. Use of an equal volume of 100% hydrazine with the synovial fluid optimised detection of hydroxyapatite. By x ray diff...

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...
