The Historically Black Colleges and Universities-Undergraduate Program (HBCU-UP) Research Initiation Awards (RIAs) provide support to STEM faculty at HBCUs to pursue research at their home institution, at an NSF-funded Center, at a research intensive institution or at a national laboratory. The RIA projects are expected to help further the faculty member's research capability and effectiveness, to improve research and teaching at their home institution, and to involve undergraduate students in research experiences. With support from the National Science Foundation, an electrochemistry research program will be established at Albany State University (ASU) where teaching and research in this field are scant. Additionally, critical issues in sustainable energy research will be integrated into undergraduate education at this predominantly African American teaching institution, which serves mainly minority, underserved students. This program will link STEM education and research by integrating fundamental principles of electrochemistry with hands-on experience in renewable energy, to produce better learning outcomes and ensure success in both college and the job market for ASU graduates. The long term goal of this project is to address issues related to renewable energy and its safe and sustainable conversion and storage in batteries for use in appropriate devices. The researchers hypothesize that electrolytes that can be used in non-polar solvents could expand the ability to test other redox-active materials, which may improve the performance of Organic Radical Batteries (ORBs) and Organic Redox Flow Batteries (ORFBs). ORBs and ORFBs offer the possibility of manufacturing lightweight and flexible devices with comparable performance but better safety than lithium-based batteries and for which increasing demands exist already. A series of weakly coordinating anions (WCAs) and cations (WCCs) featuring polysubstituted tetraarylphosphonium/tetrakis(pentafluorophenyl)borate salts will be synthesized as novel electrolytes to enable electrochemistry in low-polarity media. Electrochemical measurement will then be conducted in non-polar solvents with electrolytes designed to be soluble in the solvents, having increased ion mobility and, therefore, improved relative conductivities. Pulse radiolysis experiments including time-resolved mid-infrared studies will be employed to determine redox potentials of redox-active molecules in non-polar solvents and, possibly to measure redox potentials in an electrolyte-free environment for the first time. Redox potential determinations in non-polar environments can be applied to a wider range of fields in science and engineering, including organic synthesis, petroleum handling in pipelines, energy, and biology. The energy community will benefit from the comprehensive results of this project as newly designed electrolytes and superior measurement of redox potentials will lead to a better understanding of energy storage by electron transfer, especially as ORBs and ORFBs. This project will be conducted in collaboration with the Brookhaven National Laboratory (BNL) and BNL's Laser Electron Accelerator Facility (LEAF).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.

历史上的黑人学院和大学本科课程（HBCU-UP）研究启动奖（RIA）为HBCU的STEM教师提供支持，以便在他们的家乡机构，NSF资助的中心，研究密集型机构或国家实验室进行研究。RIA项目预计将有助于提高教师的研究能力和有效性，改善其所在机构的研究和教学，并让本科生参与研究体验。在美国国家科学基金会的支持下，奥尔巴尼州立大学（ASU）将建立一个电化学研究计划，因为该领域的教学和研究都很缺乏。此外，可持续能源研究中的关键问题将被纳入这所以非裔美国人为主的教学机构的本科教育中，该机构主要为少数族裔、服务不足的学生提供服务。该计划将通过将电化学的基本原理与可再生能源的实践经验相结合，将STEM教育和研究联系起来，以产生更好的学习成果，并确保ASU毕业生在大学和就业市场取得成功。该项目的长期目标是解决与可再生能源及其安全和可持续的转换和储存在电池中以供适当设备使用有关的问题。研究人员假设，可用于非极性溶剂的电解质可以扩展测试其他氧化还原活性材料的能力，这可能会提高有机自由基电池（ORB）和有机氧化还原液流电池（ORFBs）的性能。ORB和ORFB提供了制造轻质和灵活的设备的可能性，这些设备具有与锂基电池相当的性能，但安全性更好，并且已经存在越来越多的需求。一系列弱配位阴离子（WCAs）和阳离子（WCCs）具有多取代的四芳基鏻/四（五氟苯基）硼酸盐将被合成为新型电解质，使在低极性介质中的电化学。然后在非极性溶剂中进行电化学测量，电解质被设计为可溶于溶剂中，具有增加的离子迁移率，因此具有改善的相对电导率。包括时间分辨中红外研究在内的脉冲辐解实验将用于确定非极性溶剂中氧化还原活性分子的氧化还原电位，并可能首次测量无电解质环境中的氧化还原电位。非极性环境中氧化还原电位的测定可应用于更广泛的科学和工程领域，包括有机合成、管道中的石油处理、能源和生物学。能源界将受益于该项目的综合成果，因为新设计的电解质和氧化还原电位的上级测量将使人们更好地了解通过电子转移进行的能量储存，特别是ORB和ORFB。该项目将与布鲁克海文国家实验室（BNL）和BNL的激光电子加速器设施（LEAF）合作进行。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
