Non-Technical Summary: Fundamental kinetics and thermodynamics understanding in materials across multiple time and spatial scales will lead to elegant methods for designing novel architectures that enable new capabilities and benefits for society. Driven by this overarching goal, this Faculty Early Career Development (CAREER) award supports research to examine an emerging versatile method for fabricating interconnected bi-continuous metal-metal composites and high-surface porous metals at nano/meso scales. The project will enable the design of new materials possessing new functions in a wide range of important fields, including sensing, actuating, energy storage and catalysis. This CAREER award will also support an integrated educational plan based on a Stony Brook University (SBU) - Brookhaven National Laboratory (BNL) collaboration. The efforts will inspire and grow a diverse student body to pursue materials science and engineering, a critical technology for our society's future. In particular, students will be inspired by gaining opportunities to study materials using advanced synchrotron X-ray techniques at the National Synchrotron Light Source II (NSLS-II). Creating synergy between a university, a national laboratory and the community will directly benefit students, researchers and the general population by enabling them to work in and/or gain inspiration and knowledge from the research being performed. Technical Summary: This CAREER award will support research that focuses on examining an emerging dealloying process: solid-state interfacial dealloying (SSID). A self-organizing process, SSID is a versatile method for fabricating bi-continuous metal-metal composites and porous metals at nano/meso scales. SSID opens a new route to synthesize such structures, particularly in non-noble metals. SSID may also potentially be used to create high surface area metal/metal oxides with high thermal stability and chemical reactivity. The processing-structure-property correlations in these materials will be characterized by in situ synchrotron techniques. A multi-modal approach will be implemented by combining different X-ray techniques at NSLS-II. The research objectives of this proposal are 1) to create a new class of nano/meso metal-metal composites and porous metal films via this SSID process, 2) to understand the fundamental mechanisms that govern its material evolution in morphology, structure and chemical composition, and 3) to correlate processing and structure with the thermal and chemical properties. The educational objectives of this proposal are to integrate synchrotron techniques in materials science and engineering education through personal research engagement and mentoring, as well as curriculum development.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.

非技术总结：在多个时间和空间尺度上对材料的基本动力学和热力学的理解将导致设计新颖架构的优雅方法，从而为社会带来新的能力和利益。在这一总体目标的推动下，该学院早期职业发展（CAREER）奖支持研究，以研究一种新兴的多功能方法，用于在纳米/介观尺度上制造互连的双连续金属-金属复合材料和高表面多孔金属。 该项目将使设计新材料具有新的功能，在广泛的重要领域，包括传感，驱动，储能和催化。该职业奖还将支持基于斯托尼布鲁克大学（SBU）-布鲁克海文国家实验室（BNL）合作的综合教育计划。这些努力将激励和发展多样化的学生群体，以追求材料科学和工程，这是我们社会未来的关键技术。特别是，学生将通过获得机会，在国家同步加速器光源II（NSLS-II）使用先进的同步加速器X射线技术学习材料的启发。在大学、国家实验室和社区之间建立协同作用，将使学生、研究人员和普通民众直接受益，使他们能够参与正在进行的研究，并/或从正在进行的研究中获得灵感和知识。 技术总结：该职业奖将支持专注于研究新兴脱合金工艺的研究：固态界面脱合金（SSID）。作为一种自组织过程，SSID是一种在纳米/介观尺度上制备双连续金属-金属复合材料和多孔金属的通用方法。SSID开辟了合成此类结构的新途径，特别是在非贵金属中。SSID还可以潜在地用于产生具有高热稳定性和化学反应性的高表面积金属/金属氧化物。这些材料的加工-结构-性能的相关性将通过原位同步加速器技术来表征。在NSLS-II将通过结合不同的X射线技术来实施多模式方法。该提案的研究目标是：1）通过这种SSID工艺创建一类新的纳米/介观金属-金属复合材料和多孔金属薄膜，2）了解其在形态，结构和化学成分方面控制材料演变的基本机制，以及3）将加工和结构与热性能和化学性能相关联。 该计划的教育目标是通过个人研究参与和指导，以及课程开发，将同步加速器技术整合到材料科学和工程教育中。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。
