Nontechnical Abstract: The University of Delaware – Materials Research Science and Engineering Center (UD MRSEC) is a network rich in scientific opportunity, spanning UD and several strategic external academic and national laboratory partnerships, including U. of Pennsylvania and the National Institute of Standards & Technology (NIST). Also known as the UD Center for Hybrid, Active, and Responsive Materials (UD CHARM), the Center is advancing foundational understanding of new materials driven by theoretical and computational predictions paired with cutting-edge experiments to enable the integration of unconventional, ultra-small, building blocks. One interdisciplinary research group (IRG) is targeting the creation of new bioinspired organic materials with the capacity to function as nanoscale machines. A second IRG aims to create hybrid inorganic quantum materials that enable new optoelectronic circuits/devices and precise control of electromagnetic radiation. With this fundamental approach in both IRGs, transformative advances in materials science are expected, enabling critical innovations in biomedicine, security, sensing, adaptable materials, and soft robotics. The close physical proximity of UD to many of the major partner institutions and industrial stakeholders, facilitates frequent in-person research, education, and outreach interactions. Furthermore, UD CHARM is providing an exciting materials science platform for diversity and education programming to under-resourced youth – targeting students from groups underrepresented in science via partnerships with two historically black colleges and universities (HBCUs, Delaware State U. and Claflin U.), a pre-college effort focused on providing undergraduate pathways for Black and Latinx youth, and an education initiative geared toward mentoring younger students in basic science and engineering.Technical Abstract: UD CHARM is harnessing the integrated power of computational design, innovative synthetic and manufacturing processes, and nanoscale characterization to unlock the substantial promise of complex synthetic materials at multiple length/time-scales - leveraging strategic control of interfaces, interactions, and synthetic specificity. This MRSEC is nucleating activities to become a hub of interdisciplinary integration and infrastructure development to drive cross-cutting materials innovation. One IRG is pioneering the use of computationally-directed pathways for non-natural amino acid assembly and functionalization to achieve emergent properties in peptide active materials, such as concerted and precise larger-scale, directed molecular motion. The team is exploiting the programmability of peptide molecular shape and chemical sequence, enabled by non-natural amino acid incorporation and solution/film processing, to develop new bioinspired materials with targeted architectures and the capacity to generate simple machine movement – all guided by computational insights. A second IRG is creating hybrid quantum materials that control terahertz (THz) functionality, to enable unprecedented control over THz radiation and THz integrated circuits/devices. The team is manipulating interfaces and interactions between constituents to create hybrid materials that seamlessly convert between THz excitations of each constituent, enable nonlinear interactions ideal for modulators or gates, and enable controlled formation and modulation of hybridized quantum states. UD CHARM is creating a materials pipeline by teaching/training in a cohesive mentoring loop. Major programming impacts include: (1) under-served K-12 students via creation of a Delaware Science Program, (2) Black and Latinx high school students by interfacing with the TeenSHARP-DE college prep program, (3) HBCU undergraduates (UGs) and faculty through a ‘Pathways to Graduate School’ program, and (4) UGs via an REU program with industrial/international partners.This project is jointly funded by the Materials Research Science and Engineering Centers (MRSEC) Program in the Division of Materials Research (DMR), the Established Program to Stimulate Competitive Research (EPSCoR), and the Office of Multidisciplinary Activities (OMA) in the Directorate for Mathematical and Physical Sciences (MPS).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：特拉华大学材料研究科学与工程中心 (UD MRSEC) 是一个充满科学机会的网络，涵盖特拉华大学和多个战略外部学术和国家实验室合作伙伴，包括宾夕法尼亚大学和美国国家标准与技术研究所 (NIST)。该中心也被称为 UD 混合、活性和响应材料中心 (UD CHARM)，正在通过理论和计算预测与尖端实验相结合，推进对新材料的基础理解，以实现非常规、超小型构建块的集成。一个跨学科研究小组 (IRG) 的目标是创造具有纳米级机器功能的新型仿生有机材料。第二个 IRG 旨在创造混合无机量子材料，以实现新的光电电路/设备和电磁辐射的精确控制。 通过这两个 IRG 的这一基本方法，材料科学有望取得变革性进展，从而实现生物医学、安全、传感、适应性材料和软机器人领域的关键创新。特拉华大学与许多主要合作机构和行业利益相关者的地理位置非常接近，有利于频繁的面对面研究、教育和外展互动。此外，UD CHARM 正在为资源匮乏的年轻人提供一个令人兴奋的多元化和教育计划的材料科学平台——通过与两所历史悠久的黑人学院和大学（HBCU、特拉华州立大学和克拉夫林大学）合作，针对来自科学领域代表性不足的群体的学生，一项专注于为黑人和拉丁裔青年提供本科途径的大学预科项目，以及一项旨在指导年轻学生的教育计划 技术摘要：UD CHARM 正在利用计算设计、创新合成和制造工艺以及纳米级表征的综合能力，在多个长度/时间尺度上释放复杂合成材料的巨大前景——利用对界面、相互作用和合成特异性的战略控制。该 MRSEC 正在开展核心活动，旨在成为跨学科整合和基础设施开发的中心，以推动跨领域材料创新。 One IRG 开创性地使用计算指导的途径进行非天然氨基酸组装和功能化，以实现肽活性材料的新兴特性，例如协调一致且精确的大规模定向分子运动。该团队正在利用通过非天然氨基酸掺入和溶液/薄膜处理实现的肽分子形状和化学序列的可编程性，开发具有目标结构和产生简单机器运动能力的新型仿生材料——所有这些都以计算洞察力为指导。第二个 IRG 正在创建控制太赫兹 (THz) 功能的混合量子材料，以实现对太赫兹辐射和太赫兹集成电路/设备的前所未有的控制。该团队正在操纵成分之间的界面和相互作用，以创建混合材料，该材料可以在每种成分的太赫兹激发之间无缝转换，实现调制器或门的理想非线性相互作用，并实现混合量子态的受控形成和调制。 UD CHARM 正在通过紧密的指导循环中的教学/培训来创建材料管道。主要计划影响包括：(1) 通过创建特拉华州科学计划，服务不足的 K-12 学生；(2) 通过与 TeenSHARP-DE 大学预科计划对接，黑人和拉丁裔高中生；(3) 通过“研究生院之路”计划，为 HBCU 本科生 (UG) 和教师提供服务；(4) 通过与工业/国际合作伙伴合作的 REU 计划，为 UG 提供服务。该项目由 材料研究部 (DMR) 的材料研究科学与工程中心 (MRSEC) 计划、刺激竞争研究既定计划 (EPSCoR) 以及数学和物理科学理事会 (MPS) 的多学科活动办公室 (OMA)。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。
