This grant provides funding for a multi-institution, multi-disciplinary project to understand the processing-structure-property relationships of composite nanoheater-joining-material structures. The focus is on joining applications at the microscale level where spatial and temporal control of temperature profiles is important in complex geometries and heterogeneous devices with temperature sensitive parts. This research aims to understand (1) the fabrication of nanoheater composites of nanoheaters and joining materials, including the effect of mixing on proper distribution of heat output; (2) the deposition of the nanoheater-joining material composite onto flexible substrates; (3) the controlled, non-contact ignition of the nanoheaters; and (4) the functionality and reliability of the joining/interconnects. Both metal-based structures and polymer adhesives will be investigated. Fabrication and deposition of the composite joining system will be done by both ultrasonic powder consolidation and printing or direct electrospinning/electrospraying. Ignition experiments and modeling of self-ignition will be conducted. Finally, joint quality and robustness will be characterized.If successful, this research will enable new ways of joining materials in conventional applications that increase productivity, reduce energy and material usage, lower costs, and broaden the range of products. This research is anticipated to lead to new ways to build microscale devices such as Lab-On-Chips, flexible electronics, micro-optical devices, sensors, medical devices, and energy and information storage devices. The project will also contribute to human resource development (especially women and minorities) and increased public understanding of STEM through collaborations with the Urban Massachusetts Louis Stokes Alliance for Minority Participation (UMLSAMP), local K-12 schools, the Museum of Science, and international partners (University of Cyprus).

该赠款为一个多机构的多学科项目提供了资金，以了解复合纳米eather型材料结构的处理结构 - 建筑关系。重点是在微观级别上连接应用程序，在微观层面上，温度曲线的空间和时间控制在复杂的几何形状和具有温度敏感零件的异质设备中很重要。这项研究旨在了解（1）纳米甲甲烷剂和连接材料的纳米仪复合材料的制造，包括混合对热输出的正确分布的影响； （2）将纳米河咖啡材料复合材料的沉积在柔性底物上； （3）纳米甲甲烷的受控的非接触点火； （4）联接/互连的功能和可靠性。将研究基于金属的结构和聚合物粘合剂。复合连接系统的制造和沉积将通过超声波粉合并和印刷或直接静电/电喷雾来完成。将进行点火实验和自命不凡的建模。最后，将表征共同的质量和鲁棒性。如果成功，这项研究将使新的方式加入材料的新方法，以提高生产率，降低能源和材料的使用，降低成本并扩大产品范围。 预计这项研究将导致构建微观设备的新方法，例如实验室芯片，灵活的电子，微光学设备，传感器，医疗设备以及能源和信息存储设备。该项目还将通过与马萨诸塞州城市少数民族参与的路易斯·斯托克斯联盟（UMLSAMP），当地的K-12学校，科学博物馆和国际伙伴（塞浦路斯大学）的合作（UMLSAMP）（UMLSAMP）（UMLSAMP）（UMLSAMP）（UMLSAMP）（UMLSAMP）（UMLSAMP）（塞浦路斯大学），将有助于人力资源开发（尤其是妇女和少数民族），并增加对STEM的公众理解。
