Monoenergetic x-ray diffraction (XRD) analysis is an established standard for the assessment of urinary stone composition. The inherent low energy of x-rays used (8 keV), however, restricts penetration depth and imposes a requirement for small powdered samples. A technique capable of producing detailed information regarding component structural arrangements in calculi non-destructively would pr...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

We evaluated friction fatigue-induced changes in the microstructure and residual stress of carburized steel. By eddy current testing (ET) x-ray diffractometry (XRD), voltage rate (after/before fatigue testing) obtained by ET had a strong correlation with retained austenite phase full width at half maximum XRD. The results are useful for analysis damage

Polyaniline nanocomposite using metal oxides have wide variety of applicability because its enhanced properties to that pure polyaniline. Here we employed titanium dioxide as the oxide synthesize polyaniline composite (PANi-TiO2 ) through chemical oxidative polymerization in-situ. The obtained PANi-TiO2 is tested for powder X-Ray diffractometry (XRD), & Scanning electron microscopy(SEM).

We successfully immobilized metalloporphyrins (MeP) in mesoporous silica coating magnetite spheres. In this sense, we prepared two different classes of core@shell supports, which comprise aligned (Fe3O4-AM-MeP, MeP=FeP or MnP) and non-aligned (Fe3O4-NM-MeP, MeP=FeP or MnP) mesoporous magnetic structures. X-ray diffractometry and energy dispersive X-ray spectroscopy confirmed the mesoporous natu...

Based on micro-Raman spectroscopy (m-Raman), micro X-ray fluorescence spectrometry (m-XRF), X-ray diffractometry (XRD) and optical microscopy, this paper presents the results of our analytical studies on the early Islamic pigments used in the Masjid-i Jame of Fahraj, central Iran. Our investigations showed that ultramarine blue and haematite were used as blue and red pigments, respectively. Mor...

The electrochemical behavior of mild steel in bicarbonate solution at different dissolved oxygen (DO) concentrations and immersion times has been studied under dynamic conditions using electrochemical techniques. The results show that both DO and immersion times influence the morphology of the corrosion products. In comparative tests, the corrosion rate was systematically found to be lower in s...

Crystal structure determinations of biological macromolecules are limited by the availability of sufficiently sized crystals and by the fact that crystal quality deteriorates during data collection owing to radiation damage. Exploiting a micrometre-sized X-ray beam, high-precision diffractometry and shutterless data acquisition with a pixel-array detector, a strategy for collecting data from ma...

The remarkable enhancement in crystalline perfection of Benzophenone crystals, induced by the presence of liquid crystals in melt during the growth, been investigated. The crystal structure was confirmed by powder X-ray diffraction. Nuclear magnetic resonance analyses depicted that liquid crystal molecules did not incorporate in the lattice of grown crystals. The high resolution X-ray diffracto...

A representative of the fluoride-containing iron pnictide high-temperature superconductors, namely CaFFeAs, was doped with sodium up to the composition Ca0.86Na0.14FFeAs for the first time. Single crystals with an edge length in the range of 0.1 – 2.0 mm were obtained via solid-state and flux syntheses, respectively. The composition of the crystals was verified by means of single crystal X-ray ...
