The goal of this grant is to advance the fundamental understanding of a new class of dynamically reconfigurable surfaces that interconvert chemical and mechanical energy and thereby, exhibit unprecedented adaptive and self-regulating behavior. The research team plans to focus on systems of nano- and micro-scale pillars embedded in stimuli-responsive gels and harness various external stimuli to trigger reversible changes in the gels, which will power the concerted movement of the embedded structures and the associated, "programmable" changes in surface properties. To guide the experiments, the PIs will explore new computational approaches that seamlessly integrate the dynamic behavior of the responsive gels, a range of external stimuli, the embedded pillars, and the molecular components that decorate the pillars and gels. Through collaborative efforts, the PIs will establish a conceptual and theoretical basis for an emerging field of adaptive mechanochemistry.If successful, the combined experimental and computational studies will facilitate the fundamental understanding of mechanochemical signal transduction and the complex, multi-scale "outputs" of these adaptive systems. Through this collaborative research, the PIs will establish a new framework for the design of adaptive materials in which external stimuli can be used to elicit coupled chemical and mechanical responses and their feedback loops. The students involved in the project will participate in high-school events to speak with underrepresented minority students and create a high-school experimentation tool in order to motivate them toward higher education in the physical sciences. The PIs and participating students will be engaged in general public activities, giving lectures and volunteering at the local Science Museum; the PIs also plan to organize a symposium on "Modeling and Synthesis of Soft Dynamic Biomimetic Materials" at a national meeting.

这笔赠款的目的是提高对新类动态可重新配置的表面的基本理解，从而使化学和机械能互动，从而表现出前所未有的适应性和自我调节行为。 研究小组计划专注于嵌入刺激性反应性凝胶中的纳米和微尺度支柱系统，并利用各种外部刺激，以触发凝胶的可逆变化，这将为嵌入式结构的协同运动和相关的“相关”，“可编程”的“表面特性”变化供电。 为了指导实验，PI将探索新的计算方法，这些方法无缝地整合了响应式凝胶的动态行为，一系列外部刺激，嵌入式支柱以及装饰支柱和凝胶的分子成分。通过协作努力，PI将为自适应机械化学的新兴领域建立概念和理论基础。 通过这项合作研究，PI将建立一个新的框架，用于设计自适应材料，其中外部刺激可用于引起耦合的化学和机械响应及其反馈回路。 参与该项目的学生将参加高中活动，与代表性不足的少数民族学生交谈，并创建一个高中实验工具，以激励他们在体育科学中进行高等教育。 PIS和参与的学生将在当地科学博物馆进行演讲和志愿活动。 PIS还计划在一次全国会议上组织一次关于“软动态仿生材料的建模和合成”研讨会。
