Trace elemental analysis was carried out in 15 anti-epileptic medicinal plants using Energy Dispersive X-Ray Fluorescence (EDXRF) technique, with EX-3600, EDXRF spectrometer. The quantitative analysis is carried out using the software nEXT. The concentrations of elements like P, S, Cl, K, Ca, Mn, Fe, Cu, Zn, Br, Se, Rb, and Sr were estimated. The presence of some of these trace elements is corr...

The tribological behaviors of graphene and graphene oxide (GO) as water-based lubricant additives were evaluated by use of a reciprocating ball-on-plate tribometer for magnesium alloy-steel contacts. Three sets of test conditions were examined to investigate the effect of concentration, the capacity of carrying load and the endurance of the lubrication film, respectively. The results showed tha...

Quantitative and semi–quantitative procedures using a portable energy dispersive X–ray fluorescence spectrometer (portable XRF) were applied to geochemical studies in fault rocks, lake sediments, soils, including paleotsunami deposits. The results obtained are as follows:

A new diagnostic spectrometer has been developed at the Naval Research Laboratory (NRL) to measure the time resolved absolute intensity of radiation emitted by the Nike laser irradiated targets. The spectrometer consists of a dispersive transmission grating of 2500 lines/mm or 5000 lines/mm and a detection system consisting of an absolutely calibrated Si photodiode array and a CCD camera. In th...

Common dispersive-type spectroscopic instruments include prism-type and grating-type, usually using a single dispersive element. The continuous imaging band is always limited by the dispersion angle. When it necessary to image two wavebands with an ultra-spectral resolution that are far apart, difficult due large diffraction To broaden spectral coverage of spectrometer, in this paper, we propos...

A setup of three high-resolution magnetic spectrometers, for simplicity named A, B and C, has been built as the central facility for the precise determination of double and triple coincidence cross sections of hadron knockout and meson production through the scattering of electrons at the Mainz microtron MAMI. The spectrometers A and C with point-to-point optics in the dispersive plane and para...

In this work La0.7Sr0.3MnO3 , one group of nanosized perovskite-type oxides were prepared by sol-gel method. The perovskite structure has been characterized by X-ray diffraction (XRD) , scanning electron microscopy (SEM) , energy dispersive X-ray spectrometer (EDX) and Fourier transform infrared (FTIR) . The nanoparticles showed the excellent adsorption properties towards reactive blue 4 (RB4) ...
