“…In one occurrence, three fragments are obtained (run #7). The main recorded high masses (> 253 amu) have already been reported in experiments such as the ultrasound/ozone oxidation process, [19] photocatalytic, [36] nonthermal plasmas, [4,[37][38][39][40][41][42][43][44][45] and a combination of AOPs. [46] Most of the AIMD simulations and the present experimental results show changes of either or both cycles, while the S-N bond is rarely affected.…”

Ab initio molecular dynamics simulations and experiments were carried out to study the interaction between plasma‐produced hydroxyl radicals and organic pollutant molecules in wastewater. The simulation method was validated on the degradation products of phenol and further applied to the more complex molecule of sulfamethoxazole (SMX). The comparison with experimentally detected intermediate products obtained during plasma treatment of SMX solutions confirms the hydroxylation of the benzene and isoxazole rings observed in some of the simulations.

Underwater discharge is the typical method used to generate plasma in a liquid phase environment and is employed in many engineering applications. This study analyzes the formation and development process of the positive streamer in water under microsecond voltage. The effects of voltage amplitude, liquid conductivity, and the presence of bubbles on the underwater discharge characteristics are analyzed by establishing a two-dimensional finite element simulation model of a needle-plate gap. The simulation results show that the electron density of the streamer in water can reach 1023 m−3, and as the applied voltage amplitude increases, the development speed of the streamer increases and the head of the stream bifurcates. Moreover, when the conductivity of the water is high, the development speed of the streamer and the density of charged particles increase. Furthermore, the presence of bubbles significantly impacts the development of the discharge morphology, causing the channel to have multiple bifurcations.
