The Chemical Structure, Dynamics and Mechanisms Program supports the CAREER award of Professor Timothy Jackson at the University of Kansas who performs research to understand the mechanisms of Manganese (Mn) enzymes and improve synthetic catalysts that catalyze a diverse array of reactions including the detoxification of reactive oxygen species in humans, the degradation of aromatics in bacteria and fungi, and the conversion of nucleotides to deoxynucleotides in pathogens. Peroxomanganese(III) (MnIII-O2) adducts have been proposed as crucial intermediates in these biological and synthetic systems. Professor Jackson will use spectroscopic and computational tools to define the structural, electronic, magnetic, and reactivity properties of peroxomanganese (III) intermediates supported by ligands relevant to biological and synthetic systems. This work will advance our understanding of Mn enzymes and aid in the development of Mn oxidation catalysts.With the support of the Chemical Structure, Dynamics and Mechanisms Program in the Chemistry Division at the National Science Foundation, Professor Timothy Jackson will perform research that can lead to better catalyst design and improved understanding of enzymes. This can ultimately translate into improved diagnostic and therapeutic medicinal agents. The outreach program is very creative and extremely well organized and planned. The proposed outreach activities will provide an opportunity for 100 middle school girls, minorities, and those from economically-disadvantaged backgrounds to explore how electromagnetic radiation (light) affects their daily lives. To integrate research and education experiences, graduate and undergraduate students will serve as camp mentors. The summer camps should have a direct and positive impact on underrepresented groups in science at the important age of middle school students. The development of a camp website with pedagogical videos will provide broad dissemination of camp materials. Some of the initial research data have already been presented in peer-reviewed journals and at professional meetings.

化学结构、动力学和机制计划支持堪萨斯大学Timothy Jackson教授的职业奖项，他从事研究以了解锰(Mn)酶的机制，并改进催化各种反应的合成催化剂，包括人类体内活性氧物种的解毒，细菌和真菌中芳香烃的降解，以及病原体中核苷酸到脱氧核苷酸的转化。过氧锰(III)(MnIII-O2)加合物已被认为是这些生物和合成体系中的重要中间体。杰克逊教授将使用光谱和计算工具来定义与生物和合成体系相关的配体支撑的过氧锰(III)中间体的结构、电子、磁性和反应性。这项工作将促进我们对锰酶的理解，并有助于锰氧化催化剂的开发。在国家科学基金会化学部化学结构、动力学和机理计划的支持下，蒂莫西·杰克逊教授将进行研究，以更好地设计催化剂，提高对酶的理解。这最终可以转化为改进的诊断和治疗药物。外展计划非常有创意，组织和计划得非常好。拟议的外展活动将为100名中学女孩、少数民族和经济困难背景的人提供机会，探索电磁辐射(光)如何影响她们的日常生活。为了整合研究和教育经验，研究生和本科生将担任夏令营导师。夏令营应该对初中生重要年龄的科学方面代表性不足的群体产生直接和积极的影响。开发一个带有教学视频的营地网站，将广泛传播营地材料。一些最初的研究数据已经在同行评议的期刊上和专业会议上发表。
