项目摘要

Nontechnical Abstract: The Materials Research Science and Engineering Center (MRSEC) at the University of California, Irvine (UCI) builds on UCI’s strengths in multidisciplinary science and engineering research to establish a major research hub for materials discovery and innovation in the Southern California academe-industry eco-system. The primary mission of this MRSEC is to establish foundational knowledge in materials science by developing new classes of materials that offer unique and broad functionalities. The MRSEC comprises two Interdisciplinary Research Groups (IRGs), each working in close collaboration to address Grand Challenges in national defense and human health. The first IRG aims to create materials which exhibit unprecedented physical properties, such as the ability to withstand extreme environments having applications in national defense. The second IRG team is addressing dynamic, responsive soft materials that are in essence living electronic materials serving as an interface with living systems for healthcare applications. Through seed projects, the UCI MRSEC engages new participants in exciting new research directions. It attracts a diverse group of scientists, including women, underrepresented minority groups, and persons with disabilities, from across the nation and trains future leaders at all academic and professional levels to address critical societal challenges. This MRSEC’s integrated activities—including novel materials research, partnerships with industry and national laboratories, entrepreneurial innovation, career development, and mentorship—are enabling a transformative long-term impact on fundamental science, advanced applications, and workforce development. Technical Abstract: The UCI MRSEC combines an experimental, computational, and theoretical framework pursuing atomic- and molecular-level design and control of structure and dynamic response through two Interdisciplinary Research Groups (IRGs). IRG 1 investigates the atomic-level structure, chemistry, thermodynamics, and kinetics of interfaces in an emerging class of Complex Concentrated Materials (CCMs) that exhibit exceptional properties such as high strength, ultra-low thermal conductivity, and extremely large dielectric constants. Understanding their structure-property relationships guides design and processing of next-generation structural and functional materials. IRG 2 investigates dissipative self-assembly strategies to understand fundamental charge-matter interactions, with the goal to produce supramolecular “living” materials. Development of conductive active materials, where assembly is fueled by chemical, electrical, and other stimuli, provides the intellectual framework for a new class of living electronic materials for bio-interfaces and biological computing. The research team leverages state-of-the-art electron microscopy facilities within the Irvine Materials Research Institute and pursues instrumentation innovations to characterize atomic-scale structure and dynamic properties. Multifaceted education, outreach, and collaborations with industry, national laboratories, and nonprofit organizations allow this MRSEC to achieve significant, long-term impact with the targeted scientific advances. This impact includes technological innovation, workforce development, and boosting of the regional and national economy. Synergistic activities provide holistic training of diverse junior scientists at all stages, from K-12, undergraduate, and graduate students to postdoctoral scholars and untenured faculty, further fostering inclusive excellence in STEM.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.

非技术摘要：加州大学欧文分校(UCI)的材料研究科学与工程中心(MRSEC)利用UCI在多学科科学和工程研究方面的优势，在南加州科学院-工业生态系统中建立了一个主要的材料发现和创新研究中心。该MRSEC的主要任务是通过开发提供独特和广泛功能的新材料类别来建立材料科学的基础知识。MRSEC由两个跨学科研究小组(IRGS)组成，每个小组都密切合作，以应对国防和人类健康方面的重大挑战。第一个IRG旨在创造出具有前所未有的物理性能的材料，例如抵御极端环境的能力，在国防上有应用。第二个IRG团队正在研究动态的、响应性的软材料，这些材料本质上是活的电子材料，用作医疗保健应用中与生命系统的接口。通过种子项目，UCI MRSEC在激动人心的新研究方向上吸引了新的参与者。它吸引了来自全国各地的不同群体的科学家，包括妇女、代表性不足的少数群体和残疾人，并培训所有学术和专业层面的未来领导人，以应对关键的社会挑战。MRSEC的综合活动--包括新型材料研究、与行业和国家实验室的伙伴关系、创业创新、职业发展和指导--正在对基础科学、高级应用和劳动力发展产生变革性的长期影响。技术摘要：UCI MRSEC结合了实验、计算和理论框架，通过两个跨学科研究小组(IRGS)追求原子和分子级别的结构和动态响应设计和控制。IRG 1研究了一类新兴的复杂浓缩材料(CCM)中界面的原子级结构、化学、热力学和动力学，这些材料具有高强度、超低导热系数和极大的介电常数等优异性能。了解它们的结构-性能关系指导下一代结构和功能材料的设计和加工。IRG 2研究耗散自组装策略，以了解基本的电荷-物质相互作用，目标是生产超分子“活”材料。导电活性材料的发展，其中组装是由化学、电气和其他刺激推动的，为用于生物接口和生物计算的新型生活电子材料提供了智能框架。研究团队利用欧文材料研究所内最先进的电子显微镜设施，追求仪器创新，以表征原子尺度的结构和动态性质。多方面的教育、推广以及与行业、国家实验室和非营利组织的合作，使这个MRSEC能够对有针对性的科学进步产生重大的、长期的影响。这种影响包括技术创新、劳动力发展以及区域和国家经济的提振。协同活动为不同的初级科学家提供全方位的培训，从K-12、本科生和研究生到博士后学者和终身教职教师，进一步培养STEM方面的包容性优秀。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
