Electron-driven radical chemistry in plasmas for emerging technologies

点击翻译按钮获取中文摘要

The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma properties. However, the poor understanding of electron interactions with OH limits our ability to reliably interpret these results. This project therefore aims to experimentally study electron interactions with the hydroxyl radical. The measured values will be applied in simulations that clarify the role of electron–OH interactions in plasma-like environments.
