Plasma self-organization on anode surfaces in 1 atm DC glow discharges remains poorly understood. This effort aims to elucidate the nature of self-organization through the experimental study of resulting patterns on liquid anode surfaces with 13 different electrolytes and thus improves our understanding of the underlying physical processes that give rise to self-organization by investigating electrolyte sensitivity. Self-organization pattern formation and behavior were studied as a function of discharge current, solution ionic strength, and their chemical property evaluation. The response of the patterns to variation in these parameters was measured using an imaging camera and optical emission spectroscopy. Observed pattern characteristic length scales for all of the electrolytes were ranged from 2 to 13mm and typically increased with current over the investigated range of 20–80 mA. Complex self-organized pattern structures not reported to date were also observed. The parameters associated with pattern formation and morphology complexity are discussed and summarized.

在1 atm直流辉光放电中阳极表面的等离子体自组织仍然知之甚少。这项工作旨在通过对13种不同电解质在液体阳极表面上形成的图形进行实验研究，来阐明自组织的本质，从而通过研究电解质的敏感性，增进我们对引起自组织的潜在物理过程的理解。研究了自组织图形的形成和行为与放电电流，溶液离子强度及其化学性质评估的关系。使用成像相机和光发射光谱法测量图案对这些参数变化的响应。所有电解质的观察到的图案特征长度标度范围为2至13mm，通常在研究的20–80 mA范围内随电流而增加。还观察到迄今尚未报道的复杂的自组织模式结构。讨论并总结了与图案形成和形态复杂性相关的参数。
