Role of volume and surface processes in the atomic oxygen loss frequency in oxygen glow discharges in Pyrex
This work aims at understanding and finding the most accurate way to estimate an effective O surface recombination probability from the temporal evolution of O(3P) density measured in modulated current conditions in the positive column of oxygen glow discharges in Pyrex, which is relevant for experimental characterization and for model inputs.

Trace Methane Destruction within the Effluent of Microwave Plasma
The authors experimentally investigated the use of microwave plasma to destroy trace methane (below 1 mol %) in a setup simulating cow barn emissions. A range of gases was evaluated in the plasma, and methane-containing air was injected downstream with the aim that excited species formed in the plasma would convert methane into valuable products and into species with a lower global warming potential, such as CO₂.

Master’s Thesis: Combined non-thermal plasma and catalytic oxidation of low concentration methane
This master´s thesis by Irzam Javed studies the effect of non-thermal plasma and the hybridized plasma-catalysis system on the methane abatement by using Dielectric Barrier Discharge (DBD) reactor. The catalysts in the hybridized plasma-catalysis system are found to enhance the selectivity towards carbon dioxde..

Can post-plasma CH4 injection improve plasma-based dry reforming of methane? A modeling study
This study evaluates the energy efficiency and conversion performance of thermal plasma-driven dry reforming of methane using a pure CO₂ plasma with post-plasma CH₄ injection, supported by chemical kinetics modeling and comparison with classical DRM approaches.
