9875754CarrawayThis is an award to support research on the thermal and photochemical induced reactions of iron in several oxidation states and chemical forms. The photochemical processes of dissolved iron subject to being complexed by natural ligands will be studied with respect to reactivity and reaction products. Thermal and photochemical reactions of iron in colloidal form and in nanoclusters will be investigated for its potential role in enhancement of reactivity attributable to the relatively large surface area of iron in those forms. The proposal leading to this award was submitted in response to the Faculty Early Career Development (CAREER) Program that emphasizes combining discovery of new knowledge with inspired teaching and enthusiastic learning. The research component is expected to lead to more efficient and versatile treatment processes as well as better understanding than now exists of the dynamic behavior of microbial nutrients. The educational component of this project will relate the underlying science associated with corrosion of iron to experiences students have had personally and indirectly as exemplified by observations of transformations of the iron hull of the Titanic during its 80 years of exposure to sea water.

9875754Carraway 该奖项旨在支持铁在几种氧化态和化学形式下的热和光化学诱导反应的研究。 将研究溶解铁与天然配体络合的光化学过程的反应性和反应产物。 将研究胶体形式和纳米团簇铁的热和光化学反应，因为这些形式的铁具有相对较大的表面积，因此其在增强反应性方面的潜在作用。 获得该奖项的提案是为了响应教师早期职业发展（CAREER）计划而提交的，该计划强调将新知识的发现与启发式教学和热情学习相结合。 该研究部分预计将带来更有效、更通用的处理过程，并比现在更好地理解微生物营养素的动态行为。 该项目的教育部分将把与铁腐蚀相关的基础科学与学生个人和间接的经历联系起来，例如观察泰坦尼克号铁船体在 80 年暴露于海水中的变化。
