MIRT: Stressed Polymers - Exploiting Tension in Soft Matter

- 你好应力聚合物-利用软物质的张力机械应力是所有生命和许多合成系统不可或缺的，从细胞和肌肉到催化剂和弹性体。它是最常见的动作、反应和刺激的基础。该MIRT的总体目标是开发软材料设计的新原理，其中材料中的机械应力通过分子工程产生，管理和收获。一个具体的目标是探索宏观材料的应力状态和它们内部特定的可寻址键的化学之间的相互作用。通过控制键张力的自我生成以及将内部和外部应力智能处理为特定化学键的激活，新材料功能将成为可能。另一个目标是设计多功能聚合物颗粒和基底，自主改变它们的形状，表面结构，机械和光学性能。该团队将进一步利用其在纳米结构物体制造方面的专业知识，以前所未有的保真度和均匀性来制备下一代形状记忆颗粒和基底，旨在通过受控应变释放来存储机械应力并将其集中在分子水平。概述的目标将通过跨学科研究，国际合作以及合成化学家，实验和理论物理学家以及北卡罗来纳州，卡内基梅隆大学和杜克大学三个校区的工程师的互动团队合作来实现。这一跨学科项目将为创新和技术转让、将科学纳入教育以及扩大代表性不足群体的参与提供相当大的机会。增加多样性以增强研究创新和合作是EMIRT的一个组成部分：种族和性别的多样性将补充思想，技能，背景和学科的多样性。教育计划包括四个关键组成部分：1）夏季研究经验的本科生集中在少数民族和妇女从邻近的历史上黑人学院和大学和女子学院的研究，教育和社会活动; 2）全年指导本科生和高中学生积极参与MIRT研究活动的全周期; 3）研究生教育与研究支持，旅游奖励和新的个人发展计划，重点是创新，多样性和沟通技巧; 4）初级研究员参与7日至12日年级的活动，以增加他们的接触，热情和兴趣，创新科学。

MIRT: Stressed Polymers - Exploiting Tension in Soft MatterMechanical stress is integral to all living and many synthetic systems, from cells and muscles to catalysts and elastomers. It underpins the most common types of actions, responses, and stimuli. The general goal of this MIRT is to develop new principles in soft materials design, ones wherein mechanical stress in materials is generated, managed, and harvested by molecular engineering. One specific goal is to explore the interplay between the stress state of macroscopic materials and the chemistry of specific, addressable bonds within them. Novel materials functions will be made possible through controlled self-generation of bond tension and the intelligent processing of both internal and external stress into activation of specific chemical bonds. The other goal is to design multifunctional polymer particles and substrates that autonomously change their shape, surface structure, mechanical, and optical properties. The Team will further exploit its know-how in the fabrication of nanostructured objects with unprecedented fidelity and uniformity to prepare the next generation of shape-memory particles and substrates, designed to store mechanical stress and focus it at the molecular level via controlled strain release. The outlined goals will be achieved through interdisciplinary research, international collaboration, and interactive teamwork of synthetic chemists, experimental and theoretical physicist, and engineers across three campuses of the University of North Carolina, Carnegie Mellon University, and Duke University. This interdisciplinary project will provide considerable opportunity for innovation and technology transfer, integrating science into education, and broadening participation of underrepresented groups. Increasing diversity for enhanced research innovation and collaboration is an integral dimension of the UNC MIRT: diversity in race and gender will complement the diversity of thoughts, skills, backgrounds, and disciplines. The education program includes four key constituents: 1) Summer Research Experience for Undergraduates focused on minorities and women from neighboring Historically Black Colleges and Universities and women's colleges with research, education, and social events; 2) Year round mentoring for undergraduate and high school students with active participation in the full cycle of MIRT research activities; 3) Graduate education with research support, travel awards and a new personal development program focused on innovation, diversity, and communication skills; 4) Junior researcher engagement for 7th-12th graders with activities to increase their exposure to, and enthusiasm and interest in, innovative science.
