项目摘要

Non-technical Abstract:The mission of the Illinois Materials Research Science and Engineering Center is to perform fundamental, innovative materials research that has applications to societal needs, while supporting interdisciplinary education and training of students in materials design, understanding, and application. The scientific research comprises two highly interdisciplinary groups. The first group aims to revolutionize our ability to store and process information, via a new type of control of magnetism in materials known as anti-ferromagnets. In particular, the research focuses on controlling the behavior of these unconventional materials, which overcome the fundamental size and switching time limits of conventional magnetic memory storage such as currently used in computer disk drives. The second research group focuses on designing electronic materials that can withstand large deformations, such as bending and crumpling. Results of this research will enable many new applications, including wearable electronics and devices integrated with biological tissues, which require electronic materials that can be reversibly bent without degrading. The research activities of the Center are tightly integrated with education, outreach, and collaborative activities. Activities focused on science communication are designed to create a cadre of effective science communicators and enable the public to better assess and appreciate scientific results. Workshops and internships foster enhanced connections between academia, industry, and national labs. Advanced training for a diverse group of undergraduates, graduate students, and postdoctoral researchers produces well-trained scientists who can push the boundaries of materials research in industry and academia, and increases the pipeline for the future scientific workforce.Technical Abstract:The mission of the Illinois Materials Research Science and Engineering Center is to perform fundamental, innovative research, broadly centered on understanding the dynamic properties of materials that has applications to societal needs, while supporting interdisciplinary education and training of students in materials design, understanding, and application. The research comprises two highly interdisciplinary groups. The Metallic Antiferromagnetic Materials: Ultrafast Charge, Lattice, and Magnetization Dynamics group advances understanding and control of metallic antiferromagnetic materials using ultrafast optics and currents, as well as fast temperature excursions. The key goal is to answer open questions concerning the coupling of magnetic order, optical fields, electronic excitations, and lattice vibrations that underlie fundamental limits on the control of magnetization dynamics. This work will enable the development of new technologies for information storage and processing. The Active Interfaces between Highly Deformable Nanomaterials group transforms understanding of the link between deformations of 2D heterostructures and molecular assemblies, and the resultant changes in electronic, chemical, and optical properties. It explores a novel regime where non-uniform deformations are large compared with material dimensions, resulting in emergent properties and functionalities. Applications include flexible, reconfigurable electronics and photonics, as well as new nano-bio technologies such as 3D sensors. The science of the Center facilitates breakthroughs in understanding and utilizing the dynamic properties of materials, advances applications in key areas, increases interest, knowledge and skills for a significant number of students at many levels, and both expands opportunities and increases the pipeline for the future scientific workforce.

非技术摘要：伊利诺伊州材料研究科学与工程中心的使命是进行基础性的、创新性的材料研究，以满足社会需求，同时支持跨学科的教育和学生在材料设计、理解和应用方面的培训。科学研究由两个高度跨学科的小组组成。第一个小组的目标是通过一种新型的反铁磁体材料的磁性控制来彻底改变我们存储和处理信息的能力。特别是，研究重点是控制这些非常规材料的行为，这些材料克服了传统磁存储器存储的基本尺寸和切换时间限制，例如目前在计算机磁盘驱动器中使用的。第二个研究小组专注于设计能够承受大变形的电子材料，如弯曲和起皱。这项研究的结果将使许多新的应用成为可能，包括可穿戴电子产品和与生物组织集成的设备，这些应用需要能够可逆弯曲而不会降解的电子材料。该中心的研究活动与教育，推广和合作活动紧密结合。以科学传播为重点的活动旨在建立一支有效的科学传播者队伍，使公众能够更好地评估和欣赏科学成果。研讨会和实习促进学术界，工业界和国家实验室之间的联系。为本科生、研究生和博士后研究人员提供的高级培训培养出训练有素的科学家，他们可以在工业和学术界推动材料研究的界限，并为未来的科学工作者增加管道。技术摘要：伊利诺伊州材料研究科学与工程中心的使命是进行基础性的创新研究，主要集中在了解材料的动态特性，这些特性可应用于社会需求，同时支持跨学科教育和培训学生在材料设计，理解和应用。该研究由两个高度跨学科的小组组成。金属反铁磁材料：超快电荷，晶格和磁化动力学小组使用超快光学和电流以及快速温度漂移来促进对金属反铁磁材料的理解和控制。主要目标是回答有关磁序，光场，电子激发和晶格振动的耦合的开放性问题，这些问题是磁化动力学控制的基本限制的基础。这项工作将有助于开发信息存储和处理的新技术。高度可变形纳米材料组之间的活性界面改变了对2D异质结构和分子组装体变形之间联系的理解，以及由此产生的电子，化学和光学性质的变化。它探索了一种新的制度，其中非均匀变形与材料尺寸相比很大，从而产生紧急的属性和功能。应用包括灵活的，可重新配置的电子和光子学，以及新的纳米生物技术，如3D传感器。该中心的科学促进了理解和利用材料的动态特性的突破，推进了关键领域的应用，提高了许多层次的学生的兴趣，知识和技能，并扩大了机会，增加了未来科学劳动力的管道。
