NON-TECHNICAL: The Materials Research Science and Engineering Center at the University of California, Santa Barbara develops and sustains the necessary human and physical infrastructure to advance materials research, education, and training in an integrative manner. The project involves a dynamic team of investigators from six different departments whose interdisciplinary research contributes to advancing three different topical areas within the three Interdisciplinary Research Groups (IRGs). Research in IRG-1 focuses on understanding interactions within novel magnetic materials to advance a plethora of applications including refrigeration and fine-scale motion control. Research in IRG-2 advances plastic materials with potential impact on chemical separations and energy storage. Inspired by nature, IRG-3 establishes the foundational design rules for creating materials for applications such as self-healing materials and materials for biological tissue replacement. The research in the different IRGs integrates the preparation of new materials with the development of forefront theories to understand them, and advanced tools to measure materials properties. In parallel, seed projects allow new researchers, venturing in exciting research directions, to join the Center. Shared experimental facilities are leveraged to support the project and strengthen interactions with industry. Developing job creation through start-ups and impacting work-force preparedness through enhancing education and outreach is a goal that threads through all of the activities of the Center.TECHNICAL: The Materials Research Science and Engineering Center at the University of California, Santa Barbara includes three IRGs. The three IRGs address fundamental problems in materials research that cannot be advanced without contributions from a team of interdisciplinary and collaborative-domain experts. The research in each IRG integrates synthesis with characterization and property measurement, accompanied by theoretical and computational efforts, to advance fundamental understanding and develop promising materials classes for a range of applications. IRG-1 aims to understand and develop unprecedented control over the couplings between strain, magnetization, and temperature in single- and multiphase intermetallic compounds to advance technologies including actuation and solid-state refrigeration. IRG-2 plans to develop novel polymeric ionic liquid chemistries, understand self-assembly and ion transport in these materials, and develop applications that incorporate the emergent properties of multi-valent ion conductivity, light-driven adaptive mechanics, switchable redox activity, and magnetic response. Inspired by natural marine materials, IRG-3 aims to discover how material assembly and innovative processing can help establish the foundational design rules for creating versatile, graded, multiphase soft materials for eventual use in applications such as advanced fabrics, packaging, additive manufacturing, and tissue replacements, as well as self-shaping, self-healing, and reconfigurable materials platforms. Alongside the research, MRSEC scientists and education staff are dedicated to improving access to science and to building a dynamic and inclusive workforce of scientists and engineers. The portfolio of education programs has a core focus on undergraduate research opportunities. Outreach activities also involve K-12 students, support of teachers to create relevant curricula, and the broader lay public, to share current excitement in materials research.

非技术性：圣巴巴拉的加州大学材料研究科学与工程中心开发和维持必要的人力和物质基础设施，以综合方式推进材料研究，教育和培训。该项目涉及来自六个不同部门的研究人员的动态团队，他们的跨学科研究有助于推进三个跨学科研究小组（IRG）内的三个不同的主题领域。IRG-1的研究重点是了解新型磁性材料中的相互作用，以推进包括制冷和精细运动控制在内的众多应用。IRG-2的研究推动了塑料材料的发展，对化学分离和能源储存具有潜在影响。受自然的启发，IRG-3建立了基本的设计规则，用于创建自修复材料和生物组织替代材料等应用。不同IRG的研究将新材料的制备与前沿理论的发展相结合，以了解它们，并使用先进的工具来测量材料性能。与此同时，种子项目允许新的研究人员，冒险在令人兴奋的研究方向，加入中心。共享的实验设施被用来支持项目并加强与行业的互动。通过初创企业创造就业机会，通过加强教育和推广影响劳动力准备，是贯穿中心所有活动的目标。技术：位于圣巴巴拉的加州大学材料研究科学与工程中心包括三个IRG。这三个IRG解决了材料研究中的基本问题，如果没有跨学科和合作领域专家团队的贡献，这些问题就无法推进。每个IRG的研究将合成与表征和性能测量相结合，并伴随着理论和计算工作，以促进基本理解并为一系列应用开发有前途的材料类别。IRG-1旨在了解和开发对单相和多相金属间化合物中应变，磁化和温度之间耦合的前所未有的控制，以推进包括驱动和固态制冷在内的技术。IRG-2计划开发新型聚合物离子液体化学，了解这些材料中的自组装和离子传输，并开发结合多价离子导电性，光驱动自适应力学，可切换氧化还原活性和磁响应的新兴特性的应用。受天然海洋材料的启发，IRG-3旨在发现材料组装和创新加工如何帮助建立基础设计规则，以创建多功能，分级，多相软材料，最终用于高级织物，包装，增材制造和组织替代等应用，以及自成形，自修复和可重构材料平台。在研究的同时，MRSEC的科学家和教育工作人员致力于改善科学的获取，并建立一支充满活力和包容性的科学家和工程师队伍。教育计划的组合有一个核心重点是本科研究机会。外联活动还涉及K-12学生，支持教师创建相关课程，以及更广泛的非专业公众，以分享材料研究的当前兴奋。
