1336364/1336643Rieker/PorterCurrent water treatment methodologies are not designed to handle emerging contamination threats derived from agricultural run-off, volatile organic compounds, and pharmaceutical residues?advanced methods are therefore needed. Plasma production in liquid water produces a host of advanced oxidation agents that have the capacity to rapidly decompose organic contaminants. The proposed effort investigates a novel method of producing plasma in bubbles immersed in water by driving them at resonance in the presence of an electric field. This effort studies the ignition physics of resonantly driven bubbles, the time evolution of plasma formation in such bubbles, and the chemistry of the active interfacial layer separating the plasma bubble and the liquid water. The understanding gained from these studies will be used to design and build a plasma reactor for the purpose of water purification. As part of the educational outreach thrust of this effort, lab tours and demonstrations will be given to visiting grade school students from programs such as the Detroit Area Pre-College Engineering Program and those sponsored by Women in Science and Engineering, using in-house fabricated plasma demonstration experiments. In addition to sponsoring a student from the Summer Research Opportunity Program (SROP), a program aimed at encouraging underrepresented students to attend graduate school, we will also integrate plasma demonstrations into the existing educational outreach effort led by the National Society of Black Engineers, which involves actually visiting at risk schools in the area for the purpose of inspiring students with hands on experiments, mini-lessons, and mentorship.

1336364/1336643 Rieker/Porter当前的水处理方法不是为了处理来自农业径流、挥发性有机化合物和药物残留的新污染威胁而设计的？因此需要先进的方法。在液态水中产生等离子体产生大量高级氧化剂，其具有快速分解有机污染物的能力。拟议的努力研究了一种新的方法，通过在电场存在下驱动气泡共振，在浸入水中的气泡中产生等离子体。这项工作研究了共振驱动气泡的点火物理，等离子体形成在这样的气泡的时间演变，以及分离等离子体气泡和液态水的活性界面层的化学。 从这些研究中获得的理解将用于设计和建造用于水净化的等离子体反应器。作为这项工作的教育推广的一部分，实验室图尔斯参观和演示将给予访问的小学学生从方案，如底特律地区大学预科工程计划和那些由妇女在科学和工程赞助，使用内部制造的等离子演示实验。 除了赞助夏季研究机会计划（SROP）的学生，该计划旨在鼓励代表性不足的学生参加研究生院，我们还将等离子体演示纳入由全国黑人工程师协会领导的现有教育推广工作，其中包括实际访问该地区的风险学校，以激发学生动手实验，迷你课程，和指导
