An improved device and process for the production of oxides of nitrogen (NOx) having a novel plasma reactor assembly (105) with a gas and water injector (104) that mixes gas (10) and water (103) to produce gas and micro-fine water droplets (106) and injects same into a plasm reactor vessel (125) between electric diodes (128, 129) to yield a nitrous-rich plasma product (107) which is useful in a variety of commercial, agriculture, medical and industrial arenas.
