“…Therefore, without a clear understanding of the interactive phenomena, a simple spatial combination of the two may result in a simple summing or even a negative effect on the process. A few fine reviews on plasma catalysis are available that will be helpful for understanding the physics underlying the interaction (Boutonnet Kizling & Jaras, 1996;Chen, Lee, Chen, Chao, & Chang, 2008;Van Durme, Dewulf, Leys, & Van Langenhove, 2008).…”
