A tremendous need exists for battery technology with enhanced storage capacity. Addressing this need requires new advances in battery fabrication strategies, such as scalable methods for creating silicon nanoparticle electrodes. The consequence would result in a broad, transformative impact across all aspects of modern life such as increasing the range of electric cars, providing more effective storage for distributed power systems, and yielding compact medical devices. Toward this vision, the aim of this fellowship project is to elucidate an advanced fabrication pathway capable of programmatic control of material microstructures across multiple length scales. The goals of this fellowship are to (1) strengthen the PI’s additive manufacturing research program with intensive training on the synthesis and multi-scale characterization of inorganic functional materials at the University of California, Santa Barbara; (2) bring long-term sustained improvements to the research and education capacity of the University of Hawaiʻi in materials science and advanced manufacturing; and (3) establish long-term collaborations and training opportunities between University of Hawaiʻi and University of California, Santa Barbara, including with the NSF-supported Materials Research Laboratory. This Research Infrastructure Improvement Track-4 EPSCoR Research Fellows (RII Track-4) project would provide a fellowship to an Assistant Professor and training for graduate student at the University of Hawaii (UH). This project advances the additive manufacture of composite materials with programmed material properties by seeking to establish the scientific foundation needed to balance time scales and length scales in hierarchical methods that combine self-assembly and field-assisted aggregation. The proposed research contributes to the state of knowledge regarding: (1) control of microstructure properties across length scales, (2) top-down design of material transport properties, (3) resultant hypothesized improvement in material performance, and (4) methodology to implement this programmatic control in a scalable manner. As many of the underlying scaling relationships will translate to other types of external fields, the outcome of this project will enable the assembly of composite materials with programmed transport properties. The research objectives are to (1) establish a framework for the hierarchical assembly of battery materials using acoustic fields and (2) elucidate the structure-property relationships of nanoparticle networks in materials fabricated by field-assisted colloidal assembly. The training and synergistic objectives are to establish a sustainable, long-term research collaboration, develop a new undergraduate course on additive manufacturing for University of Hawaiʻi, initiate new collaborations with University of California, Santa Barbara, and establish a mutual student exchange program with the MRL. The project impact will be sustained through joint publications, collaborative proposals, student co-advising, and collaborations between institutes at University of California, Santa Barbara and University of Hawaiʻi.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.

对电池技术的巨大需求具有增强的存储容量。解决此需求需要新的电池织物策略进展，例如用于创建硅纳米颗粒电极的可扩展方法。结果将导致在现代生活的各个方面产生广泛的变革性影响，例如增加电动汽车范围，为分布式电力系统提供更有效的存储，并产生紧凑的医疗设​​备。朝向这个愿景，该奖学金项目的目的是阐明能够在多个长度尺度上对材料微观结构进行编程控制的高级制造途径。该奖学金的目标是（1）通过对加利福尼亚大学圣塔芭芭拉分校的无机功能材料的合成和多尺度表征进行深入的培训来加强PI的增材制造研究计划； （2）为夏威夷大学材料科学和高级制造业的研究和教育能力带来长期持续的改善； （3）在夏威夷大学和加利福尼亚大学圣塔芭芭拉分校之间建立长期合作和培训机会，包括与NSF支持的材料研究实验室。该研究基础设施改进Track-4 Epscor Research Fellows（RII Track-4）项目将为夏威夷大学（UH）的研究生助理教授和培训提供奖学金。该项目通过寻求建立在层次尺度和长度尺度的层次方法中，将复合材料与编程材料属性的额外制造与编程材料属性进行了推进，以结合自组装和现场辅助聚合。拟议的研究有助于有关以下方面的知识状态：（1）控制长度范围内的微观结构特性，（2）材料传输特性的自上而下设计，（3）随之而来的假设改善材料性能，以及（4）以可扩展方式实施这种程序化控制的方法。由于许多基础缩放关系将转化为其他类型的外部字段，因此该项目的结果将使复合材料具有带有编程的传输属性的组装。研究对象是（1）建立一个使用声场的电池材料层次组装的框架，（2）阐明纳米颗粒网络在由磁场辅助胶体组装构成的材料中的结构 - 特质关系。培训和协同目标是建立可持续的长期研究合作，为夏威夷大学额外制造的新本科课程开发新的本科课程，与加利福尼亚大学圣塔芭芭拉分校启动新的合作，并与MRL建立共同的学生交流计划。该项目的影响将通过联合出版物，协作提案，学生共同审议以及加利福尼亚大学，圣塔芭芭拉大学和夏威夷大学的研究所之间的合作来维持。该奖项反映了NSF的法定任务，并被认为是通过评估基金会的智力和更广泛的影响来通过评估来获得支持的珍贵。
