NON-TECHNICAL DESCRIPTION: Significant technological advancement relies on creating new materials with unprecedented functions or improving existing materials for superior performance. This project aims to pave a new path beyond the current state of the art for designing and discovering functional materials by understanding the impacts of defects. Defects in materials are disruptions to the periodic order of atom arrangements and serve as a double-edged sword. On one hand, defects are critical to delivering many key properties of materials, for instance, fast ion conduction necessary for energy storage with high-energy and high-power densities, and on the other hand, they can lead to materials performance failure such as short-circuit in batteries, instability, or short lifetime. The new knowledge gained from this research activity fills the gap in fundamental understanding of defect chemistry, enables controlled creation of functional defects in technologically important materials, and allows minimization of detrimental defects for improved materials performance. The outcomes advance technologies such as energy conversion and storage, data manipulation, sensors, and actuators. Students trained within this project will typically find employment in national laboratories engaged in R&D of chemical and materials science, or high-tech industries that enable novel technologies - both pathways can enhance national competitiveness. TECHNICAL DETAILS: The lack in understanding structural defects, including their nature and function, has limited the proper employment of defects to enhance materials performance or to minimize performance failures. This project aims to achieve controlled defect creation in functional materials in order to deliver new properties or significantly enhance materials performance by characterizing, understanding, and predicting defects at different time and length scales. This research combines theoretical investigation and advanced characterization (nuclear magnetic resonance spectroscopy and imaging and high-resolution transmission electron microscopy) to examine defect formation, evolution, and their impacts on ion conduction and materials stability in 3D solid ion conductors. The insights gained will transform materials design and lead to more efficient materials discovery for technological advancement in energy storage. University students (at both the undergraduate and graduate levels) are trained in first principles calculations, materials informatics approaches, advanced materials synthesis and/or characterization. A materials chemistry seminar program in partnership with a historically black institution is established to recruit minority students. High-school internship and middle school mentorship programs at FSU are leveraged to engage K-12 students in scientific research.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.

非技术描述：重大的技术进步依赖于创造具有前所未有的功能的新材料或改进现有材料以获得上级性能。该项目旨在通过了解缺陷的影响，为设计和发现功能材料铺平一条超越当前技术水平的新道路。材料中的缺陷破坏了原子排列的周期性秩序，是一把双刃剑。一方面，缺陷对于提供材料的许多关键特性至关重要，例如，高能量和高功率密度的能量存储所需的快速离子传导，另一方面，它们可能导致材料性能故障，例如电池短路，不稳定或寿命短。从这项研究活动中获得的新知识填补了对缺陷化学的基本理解的差距，使得能够在技术上重要的材料中控制功能缺陷的产生，并允许最大限度地减少有害缺陷以改善材料性能。这些成果推动了能源转换和存储、数据处理、传感器和执行器等技术的发展。在本项目中培训的学生通常会在从事化学和材料科学研发的国家实验室或能够实现新技术的高科技行业找到工作-这两种途径都可以提高国家竞争力。 技术规格：缺乏对结构缺陷的理解，包括它们的性质和功能，限制了缺陷的适当使用，以提高材料的性能或最大限度地减少性能故障。该项目旨在实现功能材料中的受控缺陷创建，以通过在不同时间和长度尺度上表征，理解和预测缺陷来提供新的性能或显着提高材料性能。该研究结合了理论研究和先进的表征（核磁共振光谱和成像以及高分辨率透射电子显微镜），以研究缺陷的形成，演变及其对3D固体离子导体中离子传导和材料稳定性的影响。所获得的见解将改变材料设计，并导致更有效的材料发现，以促进储能技术的进步。大学生（本科生和研究生）接受第一原理计算，材料信息学方法，高级材料合成和/或表征方面的培训。与一个历史上的黑人机构合作建立了一个材料化学研讨会项目，招收少数民族学生。FSU的高中实习和中学导师计划旨在吸引K-12学生参与科学研究。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
