Planning IUCRC at University of Cincinnati: Center for Hierarchical Emergent Materials (CHEM)

分层紧急材料中心（CHEM）将把学术研究人员与化学合成、流变学、形态学、模拟和建模方面的专业知识结合起来；与涂料、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一起，开发一种新的方法来设计、模拟和建模影响工程性能的新兴多层次结构。学术研究人员已经擅长于构建分子到纳米尺度的结构，用于靶向自组装。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，以控制紧急结构，这些结构控制油漆、增强弹性体、油墨、保健产品和塑料等工程材料的光泽、雾度、生物相容性、电导率和离子电导率以及韧性等特征。例如，油漆在加工、储存、应用和干燥时发生的现象。在这一过程中，颜料的纳米聚集体和团聚体可能会破裂、重组，并最终在复杂的多结构层次中产生从原子尺度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度和性能具有时间依赖性。“4 d材料”。当油墨在纸上干燥时，就会形成与光相互作用的多层结构。在轮胎制造中也产生了类似的结构层次，并导致与结构层次相耦合的动态层次，这对道路性能很重要。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，这些合作伙伴可以利用所开发的技术。在不同的领域寻找平行的方法，该中心将利用现有的合成、加工和模拟方法应用于新的领域，例如，利用增强弹性体的知识或结构的出现来生产用于锂电池的新型纳米复合固体电解质。一个以少数民族、残疾人和女性为重点的本科研究项目（REU）将与该中心联系起来，学生将来自三个校区和研究项目的工业合作伙伴。分层材料中心（CHEM）的目标主要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直接影响性能的复杂分层结构的出现。这些产品在一系列行业中非常普遍，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。该中心的范围包括流变学、结构、模拟和建模等领域，这些领域可以为油漆、油墨、增强弹性体、复杂的个人保健产品、聚合物化合物、多相催化剂和印刷电子等领域的复杂紧急结构提供见解和发现。所有这些领域都依赖于化学和纳米级工程，随后的加工导致纳米到微米级多层次结构的出现，这些结构与工程特性直接相关。该中心的影响将是新的预测模拟和模型，新方法部分通过借鉴不同学科的应用概念，新产品和工艺，利用对这些动态新兴材料的科学理解而获得。分层紧急材料中心（CHEM）由来自密歇根大学、辛辛那提大学和特拉华大学三所大学的研究人员组成。该中心将分为三个重点：1 .无序结构层次，包括增强弹性体、合成皮肤和色素；2。有序结构层次，包括半晶材料和自组装的合成方法；ⅲ。表面活性剂和凝聚体，包括蠕虫状胶束、凝聚体和生物识别组装。该奖项反映了美国国家科学基金会的法定使命，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。

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 goal of the Center for Hierarchical Materials (CHEM) is to address mostly 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 scope of the center is in areas where rheology, structure, simulation, and modeling can yield insight and discovery for complex emergent structures such as in paint, inks, reinforced elastomers, complex personal health care products, polymer compounds, heterogeneous catalysts, and printed electronics to name a few areas. All of these areas rely on chemical and nano-scale engineering followed by processing that lead to the emergence of nano-to micron-scale multi-hierarchical structures tied directly to engineering properties. 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 Center for Hierarchical Emergent Materials (CHEM) assembles a team of researchers 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.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.
