The Division of Chemistry supports Thomas Lyons of the University of North Carolina at Chapel Hill as an American Competitiveness in Chemistry Fellow. Dr. Lyons will develop new transition metal-containing catalysts for transfer dehydrogenation of alkanes, using molecular oxygen as a hydrogen acceptor. He will collaborate with scientists at Eastman Chemical to develop the methodology in a process-chemistry environment. For his plan for broadening participation, the PI will work with colleagues at the Morehead Planetarium and Science Center and LearnNC to develop high-school curriculum materials that illustrate the role of catalysts in chemistry. Many of the students served in this project will come from economically disadvantaged communities.Research like that of Dr. Lyons is aimed at developing better routes for the synthesis of pure chemical compounds. These chemicals are ultimately used in consumer products as well as in pharmaceuticals. The particular methods that Dr. Lyon is developing are "green" in that they use environmentally benign reagents (oxygen) and produce relatively benign waste (water). In addition, the processes developed should use significantly less energy than current high-temperature methods used in industry today. The hope is to develop more sustainable ways to produce the chemical compounds that modern society depends upon. The efforts at broadening participation being pursued by Dr. Lyon are aimed at giving economically disadvantaged students in North Carolina (and beyond) exposure to real-world examples of important chemical phenomena with the goal of increasing the participation of talented students from these groups in the technological workforce.

化学部支持查佩尔山的北卡罗来纳州大学的托马斯里昂作为美国化学竞争力研究员。 里昂博士将开发新的过渡金属催化剂，用于烷烃的转移脱氢，使用分子氧作为氢受体。 他将与伊士曼化学公司的科学家合作，在工艺化学环境中开发该方法。 对于他扩大参与的计划，PI将与Morehead天文馆和科学中心以及LearnNC的同事合作，开发高中课程材料，说明催化剂在化学中的作用。 许多参与这个项目的学生将来自经济上处于不利地位的社区。像里昂博士这样的研究旨在开发更好的合成纯化合物的路线。 这些化学品最终用于消费品和药品。 里昂博士正在开发的特殊方法是“绿色”的，因为它们使用环境友好的试剂（氧气），产生相对友好的废物（水）。 此外，所开发的工艺应比目前工业中使用的高温方法使用更少的能源。 希望是开发出更可持续的方法来生产现代社会所依赖的化合物。 里昂博士所追求的扩大参与的努力旨在让北卡罗来纳州（及以外地区）经济困难的学生接触到重要化学现象的真实例子，目的是增加这些群体中有才华的学生在技术劳动力中的参与。
