We present a new multi-wavelength study of supernova remnant (SNR) B0513–692 in the Large Magellanic Cloud (LMC). The remnant also has a strong, superposed, essentially unresolved, but unrelated radio source at its north-western edge, J051324– 691049. This is identified as a likely compact H ii region based on related optical imaging and spectroscopy. We use the Australia Telescope Compact Arra...

Diffuse coplanar surface barrier discharge (DCSBD) as the source of nonequilibrium plasma is widely used nowadays for surface modification of different materials. DCSBD plasma consists of many microdischarges which are moving along the planar dielectric plate and create a thin layer of macroscopically homogeneous plasma above dielectric. The influences of humidity in carrier gas at atmospheric ...

Pulse modulated hollow cathode RF plasma jet system was used for deposition of BaxSr1-xTiO3 (BSTO) and SrTiO3 (STO) thin films on Si and on multi-layer Si/SiO2/TiO2/Pt substrates. Optical emission spectroscopy was used for control of concentration of particles sputtered from the hollow cathode. Relation between ratio of spectral intensity of Ba, Ba, Sr and Sr lines and ratio of Ba and Sr concen...

Low-temperature and low-pressure plasma was investigated by OES (optical emission spectroscopy) in the range 200–1100 nm. For displaying measured emission spectra and identification of spectrum lines the software Spectrum Analyzer was used. Two modes of glow discharge present in the DC cylindrical magnetron apparatus which were previously researched by a mass spectrometer were studied by OES. T...

manganese zinc ferrite nanoparticles (mzf nps) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. to improve the colloidal stability of mzf nps for biomedical applications, nps were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (tpp) as crosslinker. the synthesized nps were characterized by x ray diffraction (xrd) analy...

This contribution is focused on the optical emission spectroscopy observations of the DC non-pulsed diaphragm discharge in various water solutions. The emission intensities of the hydroxyl radicals and the atomic lines of some selected elements are investigated. We have also studied the influence of the experimental conditions (for example of the applied high voltage and the discharge power, pH...

This work is focused on the optical emission spectroscopy observations of the DC non-pulsed diaphragm discharge in various water solutions of selected organic dyes (Direct Blue 106 and Solvent Yellow 94), a mixture of humic acids and alkaline metals. The emission intensity dependencies of hydrogen and oxygen spectral lines on initial conductivity are studied and compared also with respect to th...
