CONFERENCE SUPPORT FOR THE 4TH INTERNATIONAL SYMPOSIUM ON NON THERMAL PLASMA (May 10-14, 2004)

第四届污染控制和可持续能源发展非热等离子体技术国际研讨会将于2004年5月10日至14日在佛罗里达州巴拿马城海​​滩举行。会议致力于推进非热等离子体工艺在环境保护领域的发展，包括在空气和水处理以及可持续能源处理方面的应用。 这次会议旨在聚集来自世界各地的专家，介绍该领域的最新进展，并讨论这些技术未来发展和研究的前景。 因此，本次会议的目标是：1）聚集致力于非热等离子体环境应用（包括空气和水处理以及可持续能源加工）的关键研究小组，2）提供一个激励性的环境，促进科学交流和讨论与该技术领域发展相关的当前最重要问题，以及3）就未来工作和发展的方向进行广泛的讨论。该奖项提供补充资金，通过一些差旅和出版费用来支持本次会议。 这次会议可以产生以下更广泛的影响。该会议将加强和促进来自不同学科和不同国家的科学家和工程师之间的合作。 它将吸引大量研究生，特别是女性和代表性不足的少数族裔，以培养下一代研究人员。 此次会议的学术价值体现在代表全球顶尖机构主要实验室的参会研究人员的高素质。 它将为 NSF 提供有用的投入，作为在这个不断发展的领域进行投资的指南。非热等离子体是一种等离子体，或自由且随机移动的离子的集合，其特征是低背景温度或能量，与高能电子相结合。 通常，非热等离子体可以使用各种高压放电（例如交流、直流和脉冲）以及电子束来产生。 非热等离子体在环境领域最大的商业应用是使用交流介质阻挡放电反应器来产生臭氧，通常随后用于水处理。 非热等离子体的其他商业应用包括发电厂和焚烧炉的烟气处理以及室内空气净化。 在过去的 15 年里，人们对测试、评估和开发用于其他应用的非热等离子体产生了极大的兴趣和研究。 这些其他应用包括处理气体中的挥发性和有害有机化合物、处理移动源废气中的氮氧化物和颗粒物、处理受污染的水中的有机、无机和生物物质、合成化学过程以及有害化学和生物制剂的销毁。 虽然臭氧发生技术相当成熟，但由于反应器性能对反应器设计和操作条件（例如气体和/或液体成分、施加电场的性质、催化剂的添加和其他因素）的高度敏感性，其他应用的开发正在深入研究中。 等离子体催化、气液放电现象和天然气碳氢化合物重整领域的最新发展特别有前景，可以有助于开发有用且高效的技术。

The 4th International Symposium on Non-thermal Plasma Technologies for PollutionControl and Sustainable Energy Development will be held in Panama City Beach, Florida, May 10-14, 2004. It is devoted to advancing the field of non-thermal plasma processes for environmental protection, including applications to air and water treatment and to sustainable energy processing. This meeting is intended to assemble experts from all over the world to present recent advances to the field and to discuss the prospects of these technologies for future development and study. The objectives of this meeting are therefore:1) to assemble key research groups working on the environmental applications of non-thermalplasma including air and water treatment and sustainable energy processing,2) to provide a stimulating environment to foster scientific exchange and discussion of the mostimportant current issues related to the development of this area of technology, and3) to conduct extensive discussions on the directions for future work and development.This award provides supplemental funding to support this conference through some travel and publication costs. This conference can lead to broader impacts as follows. The conference will enhance and promote collaboration among scientists and engineers from large variety of disciplines and from a wide range of nations. It will engage a number of graduate students, and particularly women and under-represented minorities in order to develop the next generation of researchers. The intellectual merit of the conference is reflected in the high quality of the participating researchers representing major laboratories from top institutions worldwide. It will provide useful input to NSF as a guide to grant investments in this evolving field.A non-thermal plasma is a plasma, or collection of free and randomly moving ions, that ischaracterized by low background temperature, or energy, in combination with highly energeticelectrons. Typically, non-thermal plasma can be produced using a wide variety of high voltageelectrical discharges (e.g., AC, DC, and pulsed) as well as with electron beams. The largestcommercial application of non-thermal plasma in the environmental field is the use of ACdielectric barrier discharge reactors for producing ozone, generally, subsequently used in watertreatment. Other commercial applications of non-thermal plasma include flue gas treatment frompower plants and incinerators and indoor air cleaning. Over the last 15 years there has beenconsiderable interest and research devoted to testing, evaluating, and developing non-thermalplasmas for other applications. These other applications include treatment of volatile andhazardous organic compounds in gases, treatment of nitrogen oxides and particulate matter fromthe exhaust of mobile sources, treatment of organic, inorganic, and biological matter incontaminated water, synthetic chemical processes, and destruction of hazardous chemical andbiological agents. While the technology for ozone generation is fairly mature, developments forother applications are intensively under investigation due to the high sensitivity of reactorperformance on the reactor design and operating conditions (e.g., gas and/or liquid composition,nature of applied electric field, addition of catalysts, and other factors). Recent developments inthe fields of plasma-catalysis, gas-liquid discharge phenomena, and hydrocarbon reforming fromnatural gas are particularly promising and can contribute to the development of useful and efficient technologies.
