项目摘要
With support from the Chemical Measurement and Imaging Program in the Division of Chemistry and partial co-funding from the Chemical Structures, Dynamics, and Mechanisms - B program, and the Solid State Materials Chemistry program in the Division of Materials Research, Dr. Niya Sa and her research team at the University of Massachusetts Boston are developing innovative approaches to advancing our understanding of the chemistry of rechargeable batteries. The work addresses global challenges in the areas of energy storage, utilization, and environmental stewardship. Dr. Sa will work to communicate the underlying science and its importance to the general public through outreach activities that seek to explain the principles of electrochemistry, battery chemistry and green chemistry to K-12 students and members of groups underrepresented in science-technology-engineering-mathematics (STEM). With this award, Dr. Sa’s team will be implementing the hybrid Dynamic Impedance Spectroscopy/Multiharmonic Electrochemical Quartz Crystal Microbalance Dissipation (DEIS EQCM-D) platform to probe complex interfacial systems. Specifically, they seek to improve understanding of the dynamic Solid Electrolyte Interphase (SEI) of energy storage materials - critical for advancing next-generation energy storage devices, yet impeded by the lack of reliable in situ experimental techniques. The major focus of this work is to enable quantification of the microscopic mass exchange that accounts for SEI dissolution, reconstruction, and instability. Coupling DEIS with EQCM-D offers a significant advance over previously reported ex situ electrochemical impedance (EIS) or gravimetric EQCM measurements. Working at the interface between analytical chemistry and material science, the Sa group seeks to advance fundamental understanding and enable new approaches to energy storage materials and electrolytes where performance characteristics are critically determined by the dynamic ion intercalation and mass transport reactions at interfaces. Students engaged in the work will be trained in state-of-the-art electroanalytical techniques, energy storage concepts, instrumentation, and simulations. Dr. Sa is working to provide educational opportunities for underrepresented groups, and to engage with the local community through collaboration with the local Science Museum.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.
在化学学部化学测量和成像项目的支持下,以及化学结构、动力学和机制B项目和材料研究部固态材料化学项目的部分共同资助下,马萨诸塞大学波士顿分校的Niya Sa博士和她的研究团队正在开发创新方法,以推进我们对可充电电池化学的理解。这项工作解决了能源储存、利用和环境管理领域的全球挑战。Sa博士将致力于通过外展活动向公众传播基础科学及其重要性,这些活动旨在向K-12学生和科学-技术-工程-数学(STEM)中代表性不足的群体成员解释电化学,电池化学和绿色化学的原理。凭借该奖项,Sa博士的团队将实施混合动态阻抗光谱/多谐波电化学石英晶体微平衡耗散(DEIS EQCM-D)平台来探测复杂的界面系统。具体来说,他们试图提高对储能材料的动态固体电解质界面(SEI)的理解,这对于推进下一代储能设备至关重要,但由于缺乏可靠的原位实验技术而受到阻碍。这项工作的主要重点是能够量化微观质量交换,这说明SEI溶解,重建和不稳定性。与之前报道的非原位电化学阻抗(EIS)或重力法EQCM测量相比,DEIS与EQCM- d的耦合提供了显著的进步。在分析化学和材料科学之间的界面工作,Sa小组寻求推进基本理解,并使能量存储材料和电解质的新方法成为可能,其中性能特征是由界面上的动态离子插入和质量传递反应决定的。从事这项工作的学生将接受最先进的电分析技术、储能概念、仪器和模拟方面的培训。Sa博士致力于为弱势群体提供教育机会,并通过与当地科学博物馆的合作与当地社区建立联系。该奖项反映了美国国家科学基金会的法定使命,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。
