This award in the Division of Chemistry supports research by Professor Mahdi Abu-Omar at Purdue University to study electron transfer, proton-coupled electron transfer, and hydrogen atom transfer reactions. In addition, the catalysis of C-H amination, nitrene transfer and hydrogen atom transfer reactions by nonheme iron(IV) imido complexes will be explored. A molecular catalyst that mimics the enzyme chlorite dismutase and is selective for chlorite dismutation to dioxygen and innocuous chloride will also be investigated. The manganese porphyrin system and nonheme catalysts that perform these reactions will be completely characterized.This research will study how electrons and atoms transfer between molecules and will investigate molecular mimics of the enzyme chlorite dismutase. These investigations involve chemical synthesis, catalysis, kinetics, and mechanisms, which will prepare postdoctoral and graduate students for academic, industrial, and government careers. Collaborations with leading scientists in Japan (Professor Fukuzumi, Osaka University) and Korea (Professor Nam, Ewha Womans University) will further broaden the students' scientific perspectives.

该奖项在化学系中支持普渡大学Mahdi Abu-Omar教授的研究，以研究电子传输，质子耦合的电子转移和氢原子转移反应。 另外，将探索非血红素铁（IV）Imido复合物的C-H氨基酸，硝基转移和氢原子转移反应的催化。 也将研究一种模仿酶的含酶的分子催化剂，并且还将研究对二恶英的含量降解和无害的氯化物的选择性。 将完全表征执行这些反应的锰卟啉系统和非血液催化剂。这项研究将研究分子之间的电子和原子如何转移，并研究酶氯酸盐歧地化酶的分子模拟物。 这些调查涉及化学合成，催化，动力学和机制，这将为学术，工业和政府职业的博士后和研究生做好准备。 与日本（大阪大学福祖米教授）和韩国（Ewha Womans University NAM教授）与主要科学家（福祖米教授）的合作将进一步扩大学生的科学观点。
