zns/glass thinlayer in high vacuum condition and $40$ degree deposition angle has been produced by resistance evaporated method with $28$ nm thickness. cabin deposition temperature zns layer was about $50c$ and substrates were kept at room temperature. the atomic force microscopy (afm) and xrd analyses are perfectly accomplished for this layer.
High-purity (SupT) and reagent-grade (ST), stoichiometric and silicate-containing α-tricalcium phosphate (α-TCP: ST0/SupT0 and Si-TCP x=0.10: ST10/SupT10) were prepared by solid-state reaction based on the substitution mechanism Ca3(PO4)(2-x)(SiO4)x. Samples were determined to be phase pure by X-ray diffraction (XRD), and Rietveld analysis performed on the XRD data confirmed inclusion of Si in ...
Composite membranes were successfully prepared using a phase-inversion method. The X-ray powder diffraction (XRD) and energy dispersive X-ray (EDX) profiles has confirmed formation of 4.8 wt % Ag/poly(vinylidene fluoride-co-hexafluoropropene) (PVDF-HFP), 3 wt % Ag-MWCNTs/PVDF-HFP (EDX surface composition of Ag nanoparticles) and 1.5 wt % MWCNTs/PVDF-HFP composite membranes. The MWCNTs crystalli...
A powder X-ray diffraction (XRD) method to enhance the signal of a specific crystalline phase within a mixture is presented for the first time. Specificity to the targeted phase relies on finding coincidences in the ratios of crystal d spacings and the ratios of elemental characteristic X-ray energies. Such coincidences can be exploited so that the two crystal planes diffract through the same s...
In this study, results of the crystallization of iron-rich glasses are summarized. Thermogravimetry (TG)±dierential thermal analysis (DTA) were utilized to explain the phase formations and the surface oxidation of FeO to yield Fe 2 O 3. The crystal phases fraction was evaluated utilizing X-ray diraction analysis (XRD). Low angle XRD technique was used to investigate the distribution of the cr...
Background and purpose: Despite the high prevalence of mechanical low back pain, its etiology remains undiscovered in most of the cases. However, there have been many speculations about its origin based on X-ray findings and hyperlordosis of lumbar spine is an important factor. In this study, attempts were made to establish a possible relation between low back pain, lumbar lordosis and lumbosac...
Inspired by some typical plants such as lotus leaves, superhydrophobic surfaces are commonly prepared by a combination of low surface energy materials and hierarchical micro/nano structures. In this work, superhydrophobic surfaces on copper substrates were prepared by a rapid, facile one-step pulse electrodepositing process, with different duty ratios in an electrolyte containing lanthanum chlo...
Nanocrystalline titanium dioxide powder is characterized for phase analysis as well as particle size and its distribution by x-ray diffraction and small angle neutron scattering measurements. Analysis of the SANS data in the momentum transfer range q = 0.1 1.8 nm reveals an average particle size of 24.82 nm in good agreement with the particle size determined earlier by transmission electron mic...
Recently, Prussian blue analogues (PBAs) have been reported to exhibit a low voltage charge/discharge behavior with high capacity (300–545 mAh/g) in lithium-ion secondary batteries (LIBs). To clarify the mechanism of low voltage behavior, we performed ex situ synchrotron radiation X-ray diffraction (XRD) and ex situ X-ray absorption spectroscopy (XAS) of a film of Na1.34Mn[Fe(CN)6]0.84·3.4H2O w...
