The one-step synthesis and characterization of nanostructured metallic platinum microspheres by a low-pressure flat flame technique is presented here. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) analyzed the as-derived powders. Collectively, the results obtained from these analyses confirmed the formation of microsphere...

Phase identification and structure determination are important and widely used techniques in chemistry, physics and materials science. Recently, two methods for automated three-dimensional electron diffraction (ED) data collection, namely automated diffraction tomography (ADT) and rotation electron diffraction (RED), have been developed. Compared with X-ray diffraction (XRD) and two-dimensional...

ZnS nanoparticles of different size have been synthesized using a colloidal particles method. ZnS nanoparticles prepared with capping agent (mercaptoethanol) then were characterized using X-ray diffraction (XRD) and UV-Vis spectroscopy. The particle size of the nanoparticles calculated from the XRD patterns has been found in the range 1.85-2.44nm. Absorption spectra have been obtained using UV-...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. cadmium oxide (cdo) nanoparticles were synthesized by using sodium dodecyl sulfate (sds), cd(oac)2.2h2o and sodium hydroxide as starting materials. the sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem). the xrd pattern proves that the final produ...

a novel complex of cadmium (ii) [cdl0.5(no3)(h2o)](1), l= n,n-bis (o-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by ir, 1hnmr spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem). the gray single crystal of compound 1 has...

This paper introducesminiPixD: a new, compact system that utilises transmission X-ray imaging and X-ray diffraction (XRD) to locate and identify materials of interest within an otherwise opaque volume. The system and the embodied techniques have utility in security screening, medical diagnostics, non-destructive testing (NDT) and quality assurance (QA). This paper outlines the design of the sys...

Different samples of ZnS nanoparticals were synthesized by chemical co-precipitation method at room temperature using zincsulphate as zinc source and sodium sulphide as sulphur source. Structural properties of synthesized ZnS nanoparticles were studied by X-ray diffraction pattern (XRD) while optical properties were examined by UV-Visible absorption spectroscopy. XRD pattern showed the as synth...

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...
