Environmental concerns have resulted in the need for alternative energy efficient methods for the removal of oxides of nitrogen ~NxOy! from atmospheric gas streams and among those techniques is plasma remediation. The devices typically used as plasma sources ~corona and dielectric barrier discharges! operate in a filamentary mode which produces radicals and gas heating in narrow channels. Trans...

Plasma remediation is being investigated for the removal of oxides of nitrogen (NxOy) from atmospheric pressure gas streams. In previous works we have investigated the plasma remediation of NxOy from N2 /O2 /H2O mixtures using repetitively pulsed dielectric barrier discharges. As combustion effluents contain large percentages of CO2, in this paper we discuss the consequences of CO2 in the gas m...

Актуальность исследования обоснована целесообразностью создания благоприятных условий при проведении термохимической обработки топливных фрагментов с целью обеспечения одновременной трансформации керамического топлива в порошкообразный материал и полного высвобождения продукта реакции из оболочки, а также удаления топливной композиции перед гидрометаллургическими операциями летучих продуктов де...

In the use of atmospheric pressure plasma jets in biological applications, the plasma-produced charged and neutral species in the plume of the jet often interact with a thin layer of liquid covering the tissue being treated. The plasma-produced reactivity must then penetrate through the liquid layer to reach the tissue. In this computational investigation, a plasma jet created by a single disch...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

Leached cinnamon soil is the main agricultural soil distributed in the North China Plain. In this research, leached cinnamon soil samples were collected in the upper basin of Miyun Reservoir (northeast of Beijing, China). The BaPS method (Barometric Process Separation) was applied to measure nitrification, denitrification and respiration rates. The rates of nitrification, denitrification and re...

Atmospheric pressure plasmas have shown great promise for the treatment of wounds and cancerous tumors. In these applications, the sample is usually covered by a thin layer of a biological liquid. The reactive oxygen and nitrogen species (RONS) generated by the plasma activate and are processed by the liquid before the plasma produced activation reaches the tissue. The synergy between the plasm...

The use of photocatalytic materials in plasma systems has the potential to enhance selectivity and yield desired products. However, surface interaction between photocatalyst is a complex process that not well understood. This work presents comprehensive study effects combining titanium dioxide (TiO2) photocatalysts with non-thermal atmospheric pressure nitrogen-oxygen plasmas, which increases p...

Carbon dioxide decomposition is a challenging target to combat climate change. Nonthermal plasmas are advantageous for this purpose because they operate at ambient conditions and can be easily scaled-up. In study, we attempt the CO2 splitting into CO O2 in parallel plate packed-bed plasma reactor moderated with Lead Zirconate Titanate (PZT) as ferroelectric component, achieving conversion rates...
