Line-dependent analyte signal suppression/enhancement by 18 common matrix elements was simultaneously investigated for MIP-OES. Li caused the strongest effect, even concentrations as low 20 mg L −1 .

In this letter, we report on the obtention of hafnium oxide (HfO(2)) nanostructures by the microwave-hydrothermal method. These nanostructures were analyzed by X-ray diffraction (XRD), field-emission gum scanning electron microscopy (FEG-SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectrometry (EDXS), ultraviolet-visible (UV-vis) spectroscopy, and photoluminescence (PL...

A comparison method for the determination (without sample pre-concentration) of uranium in ore by inductively coupled plasma optical emission spectrometry (ICP-OES) has been performed. The experiments were conducted using three procedures: matrix matching, plasma optimization, and internal standardization for three emission lines of uranium. Three wavelengths of Sm were tested as internal stand...

zno and zno: mn nanocrystals synthesized via reverse micelle method. the structural properties nanocrystals were investigated by xrd and transmission electron microscopy (tem). the xrd results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. the various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...

Determination of the content chemical elements occurring in waste large, small and trace amounts was performed using two instrumental analysis techniques: ICP-OES—Inductively Coupled Plasma Optical Emission Spectrometry WDXRF—Wavelength Dispersive X-ray Fluorescence Spectrometry. Since such analyses are expensive time-consuming, objective work presented this paper development a quick inexpensiv...

Tribotechnical diagnostics as an integrated conception deals with the assessment of lubricants properties, monitoring of behaviour and consequences of the lubricant degradation process during its work in the machine lubrication system. For tribodiagnostic of friction pairs of aircraft engine are used three basic methods dealing with the qualitative and quantitative determination of wear particl...

static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (qcls) studied theoretically in this paper. the present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. two equations were derived to calculate the noise and modulation response. calcula...

In the present work, effect of cylindrical configurations sputtering device electrodes on plasma parameters (Debye length, electron temperature, density, frequency) is studied. Also, argon gas pressure discharge properties examined with pressures (0.08, 0.2, 0.4 and 0.6) Torr. The are diagnosed by optical emission spectrometry. spectroscopic method adopted for examining atomic spectra emission....
