Glow discharge polymerization is not well understood due to the rapid/complex reaction at plasma/gas precursor interface. Plasma in a submerged condition allows post-plasma-polymerization, leading further polymer growth and thus stable structure. Electron collision with acetonitrile interface initiates formation of radical monomers, which undergoes rearrangement form low-molecular (LM) nitrogen polymers (NPs). The radical-rich LM NPs go through polymerization, forming high-molecular (HM) (as...

Plasma‐assisted CO 2 decomposition is a promising strategy for mitigating emissions. This study integrates nonthermal atmospheric pressure plasma jet (NTAPPJ) system with CuO catalysts to enhance conversion, selectivity, and energy efficiency through synergistic plasma–catalyst interactions. Optimization of discharge power flow rate reveals that higher increases output but reduces efficiency, while elevated rates improve yield decrease conversion rates. Optimal conditions (100 W, 10 sccm...
