Plasmas in contact with liquids are a rich source of OH radicals and have been extensively studied in the last decade to leverage the ability to generate chemically reactive species in gas phase plasmas to decompose organics. Multiphase transfer of OH radicals is highly transport limited and to overcome transport limits, the plasma activation of aerosols, small liquid droplets, interspersed in the plasma has been proposed. In this work, we report a combined experimental and modeling study of a controlled plasma–droplet interaction experiment using a diffuse RF glow discharge in He + 0.2% H 2 O with detailed plasma diagnostics, ex situ analysis of the plasma-induced chemistry in the droplet containing formate, droplet trajectory and size measurements. This enables a quantitative study of the reactivity transfer of OH from the gas phase plasma to the liquid phase and how its diffusion limitations impact formate decomposition in the water droplet. For a droplet with...

受控的血浆-液滴相互作用：血浆-液体相互作用中OH转移的定量研究

与液体接触的等离子体是OH自由基的丰富来源，并且在过去的十年中进行了广泛的研究，以利用在气相等离子体中产生化学反应性物质的能力来分解有机物。OH自由基的多相转移受到高度的运输限制，并且为了克服运输限制，已经提出了散布在等离子体中的气溶胶，小的液滴的等离子体活化。在这项工作中，我们报告了使用He + 0.2％H 2 O中的弥散RF辉光放电进行控制的等离子体-液滴相互作用实验的组合实验和模型研究，并进行了详细的等离子体诊断，并在现场对等离子体诱导的化学成分进行了非原位分析。含甲酸盐的液滴，液滴轨迹和尺寸测量值。这使得能够定量研究OH从气相等离子体到液相的反应性转移，以​​及其扩散限制如何影响水滴中的甲酸盐分解。对于具有...的液滴
