Cover Story: Micro-nanobubbles (MNBs) technology has emerged as an effective means of sewage treatment. The reactive molecular dynamics simulation technique has been used to study the degradation mechanism of the pollutants caused by shock-induced nanobubble collapse. The simulation results indicate that the propagating shock wave can induce nanobubble collapse, and the collapsing bubble has the ability to focus mechanical energy, leading to the formation of a high-speed jet. The results reveal the mechanical nature of long-chain pollutant degradation and the mechanism of free radical generation. It is also found that adding ozone molecules would introduce an additional dehydrogenation mechanism. View this paper
