The Center for Hierarchical Emergent Materials (CHEM) will couple academic researchers with expertise in chemical synthesis, rheology, morphology, simulation, and modeling; with industrial manufactures of paints, pigments, printed electronics, biomedical devices, consumer products, tires and elastomers to develop a new approach to the design, simulation, and modeling of emergent multi-hierarchical structures that impact engineered properties. Academic researchers have been adept at the construction of molecular to nanoscale architectures for targeted self-assembly. Industrial researchers, on the other hand, have been equally adept at the manipulation of manufacturing and application/use conditions to control emergent structures that govern features like gloss, haze, biocompatibility, electrical and ionic conductivity, and toughness in engineered materials like paint, reinforced elastomers, inks, healthcare products and plastics. An example might be phenomena that occur when paint is processed, stored, applied, and dried. During this process pigment nano-aggregates and agglomerates may breakup, reform, and finally produce an emergent network structure that spans atomic to macroscopic scales in a complex multi-structural hierarchy. Often the multi-hierarchies have time dependence to their structural maturation and performance, i.e. "4D materials". This is the case as an ink dries on paper developing a multi-hierarchical structure that interacts with light. Similar structural hierarchies are produced in tire manufacturing and lead to a dynamic hierarchy, coupled to the structural hierarchy, important to road performance. Such complex emergent systems can only be studied by a team of academic researchers in close interaction with their industrial partners who can take advantage of the technology which is developed. Finding parallel approaches in divergent fields, the center will leverage existing synthetic, processing and simulation approaches in application to new fields, for instance, taking advantage of knowledge or emergence of structure in reinforced elastomers to produce new nanocomposite solid electrolytes for lithium batteries. An undergraduate research program (REU) focusing on minorities, the handicapped, and women will be associated with the Center, with students integrated across the three campuses and industrial partners for research projects. The Center for Hierarchical Emergent Materials (CHEM) assembles a team of twelve world leaders in research from three universities, the University of Michigan, the University of Cincinnati and the University of Delaware. The center will be organized in three thrusts: I. Disordered Structural Hierarchies including reinforced elastomers, synthetic skin, and pigments; II. Ordered Structural Hierarchies including semi-crystalline materials and synthetic approaches to self-assembly; and III. Surfactants and Coacervates including worm-like micelles, coacervates, and biometric assembly. The goal of the Center for Hierarchical Materials (CHEM) is to address chemical and biological products and processes where chemical and nanoscale manipulation and processing lead to the emergence of complex hierarchical structures with direct impact on performance. These products are extremely common across a range of industries, yet have not been studied in a coherent, interdisciplinary manner, making full use of technical and scientific expertise and advances. The impact of the center will be in new predictive simulations and models, new approaches garnered partly by borrowing concepts across the different disciplines of application, new products and processes that take advantage of scientific understanding of these dynamic emergent materials. The University of Delaware has several unique analysis capabilities that will facilitate the research of faculty, students, and industrial partners who participate in CHEM. These the Center for Advanced Microscopy (CAMM) and Microanalysis and the Advanced Materials Characterization Laboratory (AMCL) in the Interdisciplinary Science and Engineering Laboratory (ISE-Lab). UD is also home to the Center for Neutron Science (CNS).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.

分层新兴材料中心（CHEM）将耦合具有化学合成，流变学，形态学，模拟和建模专业知识的学术研究人员;与油漆，颜料，印刷电子，生物医学设备，消费品，轮胎和弹性体的工业制造商开发一种新的方法来设计，模拟和建模影响工程特性的新兴多层次结构。学术研究人员已经擅长于构建分子到纳米级的结构，用于有针对性的自组装。另一方面，工业研究人员同样擅长操纵制造和应用/使用条件，以控制新兴结构，这些结构控制着油漆、增强弹性体、油墨、医疗保健产品和塑料等工程材料的光泽度、雾度、生物相容性、电导率和离子电导率以及韧性等特征。一个例子可能是在油漆加工、储存、应用和干燥时发生的现象。在此过程中，颜料纳米聚集体和附聚物可能分解、改革，并最终产生在复杂的多结构层次中跨越原子到宏观尺度的新兴网络结构。通常，多层次结构对其结构成熟和性能具有时间依赖性，即“4D材料”。这是因为墨水在纸上干燥，形成与光相互作用的多层次结构。在轮胎制造中产生类似的结构层次，并导致动态层次，与结构层次耦合，对道路性能很重要。这种复杂的紧急系统只能由一组学术研究人员与他们的工业合作伙伴密切互动来研究，他们可以利用开发的技术。在不同领域寻找并行方法，该中心将利用现有的合成，加工和模拟方法应用于新领域，例如，利用增强弹性体中的知识或结构的出现来生产新的纳米复合材料固体电解质用于锂电池。一个本科研究计划（REU）侧重于少数民族，残疾人和妇女将与该中心，与学生在三个校区和工业合作伙伴的研究项目集成。分层涌现材料中心（CHEM）汇集了来自密歇根大学、辛辛那提大学和特拉华州大学三所大学的12名世界领先的研究团队。该中心将组织在三个重点：一。无序的结构层次，包括增强弹性体，合成皮肤，和颜料; II。有序结构层级，包括半结晶材料和自组装的合成方法;和III.表面活性剂和凝聚体，包括蠕虫状胶束、凝聚体和生物测定组装。分层材料中心（CHEM）的目标是解决化学和生物产品和工艺，其中化学和纳米级操作和处理导致出现复杂的分层结构，直接影响性能。这些产品在一系列行业中非常常见，但尚未以连贯的跨学科方式进行研究，充分利用技术和科学专业知识和进步。该中心的影响将体现在新的预测模拟和模型中，新的方法部分是通过借用不同应用学科的概念，新的产品和工艺来利用对这些动态新兴材料的科学理解。特拉华州的大学有几个独特的分析能力，这将促进教师，学生和工业合作伙伴谁参与化学研究。这些中心的先进显微镜（CAMM）和微分析和先进材料表征实验室（AMCL）在跨学科科学与工程实验室（ISE-实验室）。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
