A four-pixel-array superconducting transition-edge sensor (TES) microcalorimeter with a mushroom-shaped absorber was fabricated for the energy dispersive spectroscopy performed on a transmission electron microscope. The TES consists of a bilayer of Au/Ti with either a 50nm or 120-nm thickness. The absorber of 5.0 μm thick is made from a Au layer and its stem is deposited in the center of the TE...

Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has ...

Given an unknown multicomponent alloy, and a set of standard compounds or alloys of known composition, can one improve upon popular standards-based methods for energy dispersive X-ray (EDX) spectrometry to quantify the elemental composition of the unknown specimen? A method is presented here for determining elemental composition of alloys using transmission electron microscopy-based EDX with ap...

The MgB2 bulks were prepared by high energy milling of Mg and B powder. The correlations among milling times, microstructure and superconducting properties were investigated in MgB2 bulks. Samples were characterized by x-ray diffraction (XRD), energy dispersive spectrometry (EDX) and scanning electron microscope (SEM), and the magnetization properties were examined by a Superconducting quantum ...

the effect of temperature variation on the growth of carbon nanotubes (cnts) using thermal chemical vapor deposition (tcvd) is presented. nickel and cobalt (ni-co) thin films on silicon (si) substrates were used as catalysts in tcvd technique. acetylene gas was used in cnts growth process at the controlled temperature ranges from 850-1000 ̊ c. catalysts and cnts characterization was carried out ...

Abstract The aim of this study was to explore the antibacterial and antioxidant efficacy nickel oxide nanoparticles (NiO NPs). Raphanus sativus ( R. ) extract mediated NiO NPs were calcined at 100, 300, 600 900 ? in a muffle furnace for 3 h. increased intensity diffraction bands X-ray (XRD) spectrum suggest that degree crystallinity increases with increasing calcination temperature. desired ele...

Energy dispersive X-ray fluorescence (EDXRF) is a rapid, straightforward method to determine sample elemental composition. A spectrum can be collected in a few minutes or less, and elemental content can be determined easily if the detector has adequate energy resolution. Radioactive alpha emitters, however, emit X-rays during the alpha decay process that complicates spectral interpretation. Thi...
