The NSF Center for Interfacial Ionics (CI2) is supported by the Centers for Chemical Innovation (CCI) Program in the Division of Chemistry. The work in CI2 is in electrochemistry – i.e., the science that underlies the design of batteries, control of corrosion (rusting), production of renewable carbon-neutral hydrogen and liquid fuels, carbon-capture technologies, and the transmission and processing of information in biology (for example, in the nervous system). Although electrochemistry inherently couples the motion of ions (atoms or molecules with positive or negative charge) and electrons, it is typically only the flow of electrons that is measured by experiments (as electrical current). This has resulted in an ‘electron-centric’ conceptual foundation that does not optimally support the design of electrochemical technologies that are limited by how ions move. The NSF CI2 will address this basic-science gap of how ions move across interfaces by building precise platforms to measure ion speeds, inventing and applying state-of-the-art analytics to understand mechanisms at molecular length scales, and using computer simulations to interpret experimental results and build improved theoretical models. This work is expected to provide a renewed foundational science of interfacial ionics that will inform the invention of new electrochemical technologies for society. The science effort leverages a diverse team of research-intensive and primarily undergraduate and minority-serving institutions to synergistically create a sustainable STEM diversity pipeline. In education, CI2 will be a flagbearer for fundamental electrochemical knowledge creation, mold the next generation of diverse leaders in the electrochemical sciences that underly technologies critical for the prosperity of humanity, and disseminate topics that engage the public via students and researchers specifically trained in effective technical and non-technical science communication techniques. Innovation and entrepreneurship training are tightly embedded in the research platform to facilitate translation of the science to commercial products for societal impact.The Center for Interfacial Ionics (CI2) has the potential to revolutionize the understanding of interfacial-ion-transfer (IIT) kinetics by coupling new measurements on molecularly tunable interfaces with advances in theory and computation to uncover accurate IIT theories of broad impact in science and technology. The technical science effort focuses on three aims: (i) developing a molecular science of IIT that connects clean measurements and tractable theory at liquid/liquid junctions to technology-relevant solid/liquid junctions, (ii) probing and tuning the free-energy landscape to understand how to catalyze IIT at liquid/liquid and solid/liquid junctions, and (iii) accelerating IIT through IIT catalysis by controlling interface-absorbed intermediates and solvation/desolvation kinetic barriers. The target outcomes of CI2 are: (i) a demonstration that the fundamental properties derived from IIT studies of well-defined liquid/liquid interfaces correlate with technologically relevant solid/liquid and solid/solid interfaces, (ii) the first IIT theory that leverages data from experiment and molecular simulations from model systems and condenses the complexity of IIT to simple formulations broadly enabling quantitative prediction, and (iii) the design and demonstration of IIT catalysts.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.

NSF界面离子中心（CI 2）由化学部的化学创新中心（CCI）计划提供支持。 CI 2的工作是电化学-即，电池设计、腐蚀控制（生锈）、可再生碳中性氢和液体燃料的生产、碳捕获技术以及生物学信息传输和处理（例如，神经系统）的基础科学。 虽然电化学本质上耦合了离子（带正电荷或负电荷的原子或分子）和电子的运动，但通常只有电子的流动才能通过实验测量（作为电流）。 这导致了“以电子为中心”的概念基础，其不能最佳地支持受离子移动方式限制的电化学技术的设计。 NSF CI 2将通过建立精确的平台来测量离子速度，发明和应用最先进的分析来理解分子长度尺度的机制，并使用计算机模拟来解释实验结果并建立改进的理论模型，来解决离子如何在界面上移动的基础科学差距。 这项工作预计将提供一个更新的基础科学界面离子学，将告知新的电化学技术的发明为社会。 科学工作利用研究密集型的多元化团队，主要是本科生和少数民族服务机构，协同创建一个可持续的STEM多样性管道。 在教育方面，CI 2将成为基础电化学知识创造的旗手，塑造下一代电化学科学的多元化领导者，这些领导者是人类繁荣的关键技术，并通过学生和研究人员传播主题，让公众参与有效的技术和非技术科学传播技术。 创新和创业培训紧密嵌入研究平台，以促进科学转化为商业产品，产生社会影响。界面离子中心（CI 2）有可能彻底改变对界面离子转移（IIT）的理解。通过将分子可调界面上的新测量与理论和计算的进展相结合，揭示在科学中具有广泛影响的精确IIT理论和技术 技术科学的努力集中在三个目标：（i）开发IIT的分子科学，其将液体/液体接合处的清洁测量和易处理的理论与技术相关的固体/液体接合处连接，（ii）探测和调整自由能景观以理解如何在液体/液体和固体/液体接合处催化IIT，和（iii）通过控制界面吸附的中间体和溶剂化/去溶剂化动力学障碍，通过IIT催化加速IIT。 CI 2的目标成果是：（i）证明了从定义明确的液体/液体界面的IIT研究中得出的基本性质与技术相关的固体/液体和固体/固体界面相关，（ii）第一个IIT理论，该理论利用来自模型系统的实验和分子模拟的数据，并将IIT的复杂性浓缩为广泛实现定量预测的简单公式，以及（iii）IIT催化剂的设计和演示。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。
