Nitrite Production and Transfer Within a Levitated Water Droplet Under Nanosecond Plasma Discharge

Year: 2026

Type: article

Abstract: ABSTRACT This study investigates nitrite formation using nanosecond plasma discharges in atmospheric air interacting with acoustically levitated water droplets in a pin‐to‐pin setup. Results show that nitrite generation correlates directly with both the number of discharges and the plasma‐droplet interface area. Droplet volume, energy and salinity significantly influence this process. The estimated production rate is a constant of 17 ± 1 pmol. mm −2 discharge −1 . Compared to other configuration (jets or dielectric barriers discharges [DBDs]), the pin‐to‐pin setup provides higher nitrite concentrations and energy yields, though its overall production rate is lower. These findings advance our understanding of plasma‐water interactions for nitrite production, highlighting the potential of this technology in agricultural and biomedical fields.
