With the support of the Chemical Catalysis Program in the Division of Chemistry, Dr. Virginia Montiel-Palma of Mississippi State University is investigating catalysts that add silicon to alkene substrates in a dehydrogenative fashion to form valuable building blocks for pharmaceutical application, medical and dental implants, and many everyday materials. Translating catalysts from the research laboratory to industry is a huge challenge. Not only do catalysts often have to be immobilized onto a solid support, but the material needs to be robust and retain the desired properties. By using state-of-the-art methods to study how these catalysts work at the molecular level, Dr. Montiel-Palma and her research group are applying this fundamental insight to design new improved catalysts that are more active and cost-efficient. Specific molecular changes are also being made to the catalysts to determine their effect on their reactivity and stability. In partnership with the Mississippi Migrant Education Center, Dr. Montiel-Palma is also giving a series of informal STEM lessons and activities for students K-12. These students are children of migratory workers with income sources in agriculture, fisheries, and other primary activities. They constitute one of the most vulnerable sectors of our society. Dr. Montiel-Palma is using this activity to address scientific topics aimed at motivating these students to finish secondary education and enrich their educational pathways.Dr. Virginia Montiel-Palma and her research group will conduct a systematic study of dehydrosilylation catalysts grafted to metal-organic framework (MOF) supports. The catalysts are being tuned at both their pincer-like ligand sites as well as in the pore size, chemical properties, and structural stability of the MOF. A multifaceted characterization plan is being used to interrogate the catalytic materials and the mechanism of dehydrosilylation using these materials. The insights gained from these investigations are to be used to further inform structural changes in an iterative catalyst development process. Taken together, these activities are expected to provide a foundational profile of the catalyst system and help design more efficient and robust dehydrosilylation systems. These studies will be conducted with a team of graduate and undergraduate students carrying out the synthetic, mechanistic, and computational aspects of this project utilizing state-of-the-art technologies. These experiences will provide multi-faceted training in support of a diverse workforce.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学催化计划的支持下，密西西比州立大学的Virginia Montiel-Palma博士正在调查催化剂，这些催化剂以脱氢方式为烷烃底物增添了硅，以形成用于制药，医疗和牙科植入物以及许多日常材料的有价值的基础。将催化剂从研究实验室转换为工业是一个巨大的挑战。不仅催化剂通常必须固定在固体支撑上，而且材料需要坚固并保留所需的特性。通过使用最先进的方法来研究这些催化剂在分子水平上的工作方式，Montiel-Palma博士和她的研究小组正在将此基本见解应用于设计新的改进的催化剂，这些催化剂更为活跃，更具成本效益。还对催化剂进行了特定的分子变化，以确定其对其反应性和稳定性的影响。与密西西比移民教育中心合作，蒙蒂尔·帕尔玛（Montiel-Palma）博士还为学生K-12提供了一系列非正式的STEM课程和活动。这些学生是农业，渔业和其他主要活动中收入来源的移民工作者的孩子。它们构成了我们社会最脆弱的部门之一。蒙蒂尔·帕尔玛（Montiel-Palma）博士正在使用这项活动来解决旨在激励这些学生完成中学教育并丰富其教育途径的科学主题。弗吉尼亚·蒙蒂尔·帕尔马（Virginia Montiel-Palma）和她的研究小组将对接枝到金属有机框架（MOF）支持的脱氢催化剂进行系统研究。催化剂在其钳子样配体位点以及MOF的孔径，化学性质和结构稳定性中都进行了调节。多方面的表征计划被用来询问使用这些材料的催化材料和脱氢硅化的机理。从这些研究中获得的见解应用于进一步为迭代催化剂开发过程中的结构变化提供信息。综上所述，这些活动有望提供催化剂系统的基础概况，并帮助设计更有效，更强大的脱氢系统。这些研究将与一支研究生和本科生的团队进行，该团队利用最先进的技术进行该项目的合成，机械和计算方面。这些经验将提供多方面的培训，以支持多样化的劳动力。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准来评估值得支持的。
