3. Project SummaryTransferring breakthroughs in nanoscale science into new technologies requires that we understand and overcome barriers to nanoscale manufacturing. In addressing the NNI Grand Challenges and the many hurdles identified at NSF Workshops on Nanomanufacturing, CHN has identified the following criticalquestions, which define the fundamental technical barriers to nanomanufacturing:1. How can we assemble different nano-scale elements? What are the mechanisms leading to the assembly and orientation of nanoscale structures? How do we control these mechanisms?2. How can we scale up assembly processes in a continuous or high rate manner? How do we control the interfacial behavior and forces required to assemble, detach, and transfer nanoelements at high rates?3. How can we test for reliability in nanostructures? How can we detect and mitigate defects?4. How can nanomanufacturing processes meet existing and future environmental and health regulations?The CHN is developing the processes and tools to overcome these fundamental barriers, with a synergistic team of three universities: Northeastern University, Boston; University of MassachusettsLowell; and University of New Hampshire, Durham. These equal partners form the Center for High-rate Nanomanufacturing (CHN). This ongoing collaborative effort has demonstrated that this effective and unique partnership, combining the skills of 39 engineers, physicists, chemists, material scientists, businessand humanities investigators with diverse expertise has the capacity to tackle these critical barriers.GoalsThe Center for High-rate Nanomanufacturing goals are:1. Understand the fundamentals of synthesis and control at the nanoscale to enable high-rate/highvolume bottom-up, precise directed assembly of nanoelements2. Translate nanoscale science to practical applications in energy, biomedical, electronics and materials.3. Develop responsible manufacturing by identifying and managing potential risks of nanotechnology4. Educate the current and emerging nanomanufacturing workforce.ProgramsThe CHN?s approach to nanomanufacturing processes is fully integrated. The CHN has made major strides to advance our vision for High-rate/high-volume nanomanufacturing. This vision includes synthesis and/or functionalization of nanoelements ; uses templates for directed assembly ; transfers assembled structures ; integrates assembled structures into test beds and emerging applications. Combined with responsible manufacturing, and cross-cutting research including modeling, reliability, and defect mitigation, the above barriers define the CHN research thrusts:Thrust 1: Synthesize nanoelements and create versatile nanotemplatesThrust 2: Employ nanotemplates to enable high-rate/high-volume manufacturingThrust 3: Proof of Concept Test Beds, Emerging Applications, and Manufacturing ReadinessThrust 4: Concurrently assess the environmental, economic, regulatory, and ethical impacts of nanomanufacturingThe CHN is defining and developing high-rate nanomanufacturing processes that will enable: Consistent nanoscale directed assembly over large areas (measured in inches or feet), fast nanoscale directed assembly (measured in minutes or seconds), assembly of a large volume of nanoelements, repeatable andhigh yield assembly processes, and assembly of reliable structures.The CHN process flow chart shown here illustrates how the different research thrusts and tasks are connected starting with nanoelements and nanotemplates (Thrust 1), continuing to their assembly and transfer (Thrust 2) and then on to the realization of test beds and applications (Thrust 3), all whileevaluating environmental and economic impacts (Thrust 4). The flow chart illustrates the highly integrated nature of CHN and also shows how a system-level focus drives the research from discovery through proof-of-concept test beds. It also shows how-multi scale modeling is used to understand and guide fundamental mechanisms in synthesis, assembly and transfer.

3.将纳米科学的突破转化为新技术需要我们理解并克服纳米制造的障碍。在解决NNI大挑战和NSF纳米制造研讨会上确定的许多障碍时，CHN确定了以下关键问题，这些问题定义了纳米制造的基本技术障碍：1.我们如何组装不同的纳米尺度元素？导致纳米结构组装和取向的机制是什么？我们如何控制这些机制？2.我们如何以连续或高速率的方式扩大组装流程？我们如何控制界面行为和所需的力量，组装，分离，并在高速率转移纳米元素？3.我们如何测试纳米结构的可靠性？我们如何检测和减轻缺陷？4.纳米制造工艺如何满足现有和未来的环境和健康法规？CHN正在开发克服这些基本障碍的流程和工具，由三所大学组成的协同团队：波士顿东北大学、马萨诸塞州洛厄尔大学和新罕布什尔州达勒姆大学。这些平等的合作伙伴组成了高速纳米制造中心（CHN）。这种持续的合作努力表明，这种有效和独特的伙伴关系，结合39名工程师，物理学家，化学家，材料科学家，商业和人文研究人员的技能与不同的专业知识有能力解决这些关键障碍。GoalsThe中心高速纳米制造的目标是：1.了解纳米级合成和控制的基本原理，以实现高速率/高容量自下而上，精确定向组装纳米元件2。将纳米科学转化为能源、生物医学、电子和材料领域的实际应用。通过识别和管理纳米技术的潜在风险，发展负责任的制造业4。教育当前和新兴的纳米制造劳动力。的方法，纳米制造过程是完全集成的。CHN在推进高速/大批量纳米制造愿景方面取得了重大进展。这一愿景包括纳米元素的合成和/或功能化;使用模板进行定向组装;转移组装结构;将组装结构集成到测试床和新兴应用中。结合负责任的制造和跨领域研究，包括建模，可靠性和缺陷缓解，上述障碍定义了CHN研究的重点：重点1：合成纳米元素并创建多功能纳米模板重点2：采用纳米模板实现高速率/大批量制造重点3：概念验证测试床，新兴应用和制造就绪性重点4：同时评估纳米制造对环境、经济、监管和道德的影响CHN正在定义和开发高速纳米制造工艺，这将使：大面积一致的纳米级定向组装（以英寸或英尺测量），快速纳米级定向组装（以分钟或秒测量），大量纳米元件的组装，可重复且高产率的组装工艺，这里显示的CHN工艺流程图说明了不同的研究重点和任务是如何从纳米元件和纳米模板开始连接的（重点1），继续组装和转移（重点2），然后实现试验台和应用（重点3），同时评估环境和经济影响（重点4）。该流程图说明了CHN的高度集成性，并展示了系统级焦点如何推动从发现到概念验证测试床的研究。它还显示了如何使用多尺度建模来理解和指导合成，装配和转移的基本机制。
