0000644 Gray This is an award to support exploratory research on the ways in which metal oxide surfaces mediate the interactions between ionizing radiation and organic compounds particularly those with large oxidation-reduction potentials such as hexachlorobenzene. Specific objectives are to determine how oxide surfaces affect reaction rates induced by ionizing radiation and to relate band energy of metal oxides to surface adsorption and rate of chemical transformations that are induced by ionizing radiation. The investigator also plans on applying knowledge gained in the initial phases of this project to explore its application for decontamination of liquids and solid materials used in production processes for potential reuse in production and in determining the feasibility of radiation-induced metal oxide catalysis in accelerating radiolysis for decontamination of contaminated soils and solutions. The proposal leading to this award was submitted to NSF under the Special Guidelines for an SGER (Small Grant for Exploratory Research) in the NSF Grant Proposal Guide (NSF 00-2). Results of this research are expected to provide the basis for further research on the potential for use of radiolysis in decontamination of contaminated soils and sediments. ***

0000644 灰色 该奖项旨在支持对金属氧化物表面介导电离辐射与有机化合物之间相互作用的方式的探索性研究，特别是那些具有大氧化还原电位的有机化合物，例如六氯苯。 具体目标是确定氧化物表面如何影响电离辐射引起的反应速率，并将金属氧化物的带能与表面吸附和电离辐射引起的化学转化速率联系起来。 研究人员还计划应用在该项目初始阶段获得的知识来探索其在生产过程中使用的液体和固体材料的净化应用，以实现生产中的潜在再利用，并确定辐射诱导金属氧化物催化加速辐射分解的可行性用于净化受污染的土壤和溶液。 获得该奖项的提案是根据 NSF 拨款提案指南 (NSF 00-2) 中的 SGER（探索性研究小额拨款）特别指南提交给 NSF 的。 这项研究的结果预计将为进一步研究辐射分解在污染土壤和沉积物净化中的潜力提供基础。 ***
