this paper describes day-one beamlines of the iranian light source facility and design concept of powder diffraction and spectromicroscopy beamlines as the most priorities of each synchrotron that cover the research requirements in the fields of physics, chemistry, nano-science, etc. for powder diffraction beamline energy range is 6-30 kev, resolution: 10-4, flux: 1012(ph/s/0.1%b.w.) and spot s...

objective(s): hardystonite (ht) has been successfully prepared by a modified sol-gel method. we hypothesized thatnano-sized (ht) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (ht).materials and methods: the hardystonite nanopowder was prepared via a modified sol-gel method.optimi...

znfe2o4 mixed spinel ferrite nanoparticles obtained through a citrate-nitrate combustion method. ignited products calcined at different temperatures in 600-900ºc range and effect of calcination treatment temperature investigated. final products characterized by x-ray diffraction (xrd), fourier-transform infrared spectroscopy (ftir), and field emission scanning electron microscopy (fesem). the a...

To compare sample data from x-ray diffraction a suitable metric is developed to evaluate the similarity (or dissimilarity) between samples and to compare it to a references. The methodology focuses on the d-lines and uses the intensity measurements indirectly in the algorithm. The resulting d-line distribution and summary statistics of the differences is used to establish whether a true differe...

a new nano-sized cobalt(ii) coordination polymer, (col1).0.5dmf.1.5ch3oh(1); [h2l1 = 5-(4-carboxy phenyl azo) salicyilic acid] has been synthesized by a sonochemical method. the thermal stability of compound 1 was studied by thermo- gravimetric and differential thermal analyses. nano-structure of this coordination polymer was characterized by elemental analyses, ir spectroscopy,  powder x-ray d...

in this work, copper oxide nanoparticles have been synthesized via extractive rosmarinus officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (ch3coo)2cu+h2o individually as cu sources. it was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0c. powder x-ray diffrac...
