摘要
Herein, a plasma microjet of argon-nitrogen mixtures is produced at atmospheric pressure. The device operation is based on a dielectric-barrier discharge generated by high-voltage positive pulses. We show the possibility to direct the excited species of the jet into flexible silicone tubes and to drastically modify the reactivity at the tube's downstream end by varying the gas composition of the jet. The induced modifications are illustrated by aesthetically pleasing images which unveil the existence of an optimum proportion of nitrogen to argon in order to achieve increased reactivity.
