In this paper, heterojunction nanowires of Ni-Se are fabricated via template-assisted electrodeposition process. Nanowires are characterized by scanning electron microscopy (SEM), Energy dispersive X-Ray Spectroscopy (EDS), X-ray diffractometry and electrical transport studies. SEM photographs reveal the uniform and dense growth of Ni-Se nanowires. X-ray diffraction pattern shows the crystallin...

The work presents results of the characterization of dust collected in ASDEX Upgrade, with the special emphasis on size, morphology, structure and composition of the dust particles. The dust particles were collected after 2009 campaign using the filtered vacuum technique. The structure and composition of the particles were examined by scanning electron microscopy (SEM) combined with energy-disp...

The same sherd was analyzed using a scanning electron microscope with energy dispersive spectroscopy (SEM-EDS) and a micro X-ray fluorescence tube attached to a scanning electron microscope (Micro-XRF-SEM) to compare the effectiveness of elemental detection of iron-based pigment. To enhance SEM-EDS mapping, the sherd was carbon coated. The carbon coating was not required to produce Micro-XRF-SE...

Silver nanoparticle rings embedded in glass are fabricated by ion exchange technique with photolithographically patterned metal mask. Optical transmission measurement is performed to characterize the optical properties of silver nanoparticles. Atomic force microscopy (AFM) of an etched sample further shows the pattern of the nanoparticles. Transmission electron microscope (TEM) with X-ray energ...

Density, chemical, structural and vibrational studies of GexSb65Se35-x system with 0 ≤ x ≤ 20 produce by melt-quench technique were carried out using Archimedes method, Energy Dispersive Spectroscopy (EDS), X-ray diffraction (XRD) and Raman spectroscopy. All specimens are polycrystalline in nature as confirmed by XRD pattern. The compositional dependence of the XRD and Raman spectra suggests th...

A comparative study of two coating methods on titanium (Ti) substrates, sol-gel and electrophoresis processes, was performed. Before coating, two different surface treatments were employed. The hydroxyapatite (HA) powder were characterized by infrared spectroscopy (FTIR) and X-ray diffraction (XRD) while coated samples were examined by using scanning electron microscopy (SEM) with energy disper...

Metal matrix nano composite coatings possess enhanced properties such as corrosion and wear resistance. This paper aims to study the corrosion behavior of pure Co and Co-BN nano composite coatings deposited with different particles concentration (5-20 g L-1) on copper substrates using electroplating technique. Morphology and elemental compositions of the coatings were investigated by means of s...
