Optical Emission of Atmospheric - Pressure Dielectric Barrier Discharge Plasma on Mercury Diiodide/Rare Gases Mixtures

“…The reaction of the collision of xenon atoms in the metastable 3 P 2 with the molecules of mercury diiodide (10) (11) [14,23].The emission of spectral bands with a maximum intensity at a wavelength λ max. = 342 nm is caused by electron-vibrational transitions D' A' of iodine molecules (reaction 12), which are formed in the reaction (13) [14].The excited mercury atoms are formed due to the reaction (13,14,15) due to the large effective cross section of dissociative excitation of mercury diiodide molecules by electrons.The emission of spectral lines of atoms and ions of xenon and neon caused by reactions (16,17).…”

“…Exciplex radiators (lasers and excilamps) that work on such mixtures provide high spectral radiation power that is important for practical applications in plant photoregulation, biotechnology and medicine. [13][14].Optical emission of gaseous mixtures, including mercury diiodidevapor, inert gases, molecular nitrogen was studied in [4][5][6][7][8][9][10][11]. Atmospheric pressure plasma in the working mixtures was produced in a glow and barrier discharges under repetitively pulsed or sinusoidalvoltage form.…”

Indication of Long-Term Changes of Algae Communities in a Hydrologically Transformed Estuary Sasyk, Black Sea, Ukraine

“…The environmental variables were collated for three periods of the Sasyk's existence: lake-estuary, formation of a reservoir, and reservoir (Table 1). Hydrological parameters (water exchange period, evaporation, inflow through the channel, and inflow of water from the sea) were gathered from literature sources or calculated by authors of published data [11][12][13][14][15] and are presented in Table 2. Hydrophysical parameters were measured during our periodical field studies in 2013-2019, with some additional information from literature sources [11][12][13][14][15] and the monitoring data of the State Water Agency and the Danube Hydrometeorological Observatory (work with unpublished data in archives).…”
