This Small Business Innovation Research Phase I project will develop a novel process capable of high-volume production of monodisperse nanoparticles of arbitrary metallic composition. Such highly-controlled materials are desired as components for engineered nanostructures. The current standard precipitate or aerosol processes for metal nanoparticle formation are limited in available materials, the particle size distribution, or productivity. In this project an adaptation to jetting processes will be used to enable formation of metal nanojets and nanoparticles. Because this is entirely a physical process, it is expected to be able to be adapted to any metal alloy. second The specific tasks of the project will inolve survey of possible approaches, analyzing the proposed process, and preparing the preliminary design of the key parts of a prototype apparatus. The objective is a system capable of the precise formation of nanojets and monosize nanoparticles at rates greater than one gram per second. Commerically, there are many possible long-term applications for metal nanoparticles. Nanoelectronics and high-density data storage are two appealing examples. The established markets for the technology described with the most initial opportunity relevant to this proposal appear to be in the following fields: solid propellants, explosives, and catalysts. Monodisperse nanoparticles will allow mechanical packing into ordered array structures for filtration. The high surface area of nanoparticles enables their use as substrates for catalysis of chemical reactions. While supported by these initial markets, further innovation in many other markets and derivative technologies (such as oxide ceramic nanoparticles, and nano-patterning devices) will be developed from this new technology. This technology offers a means of producing significant quantities of monodisperse nano-spheres at commodity prices. It also enables further significant innovations in nanoscale fabrication, materials and processing.

这个小企业创新研究第一阶段项目将开发一种能够大批量生产任意金属成分的单分散纳米颗粒的新工艺。这种高度可控的材料是工程纳米结构的理想组成部分。目前用于金属纳米颗粒形成的标准沉淀或气溶胶工艺在可用材料、粒度分布或生产率方面受到限制。在这个项目中，对喷射过程的适应将用于形成金属纳米射流和纳米颗粒。由于这完全是一个物理过程，因此有望适用于任何金属合金。该项目的具体任务将包括调查可能的方法，分析拟议的过程，并准备原型装置关键部件的初步设计。目标是一个系统能够精确地形成纳米射流和单一尺寸的纳米颗粒的速率大于每秒一克。在商业上，金属纳米颗粒有许多可能的长期应用。纳米电子学和高密度数据存储是两个吸引人的例子。与本建议有关的最具初步机会的技术的既定市场似乎在以下领域：固体推进剂、炸药和催化剂。单分散纳米颗粒将允许机械包装成有序的阵列结构过滤。纳米颗粒的高表面积使它们能够用作催化化学反应的底物。在这些初始市场的支持下，许多其他市场和衍生技术（如氧化陶瓷纳米颗粒和纳米图案设备）的进一步创新将从这项新技术中发展出来。这项技术提供了一种以商品价格生产大量单分散纳米球的方法。它还使纳米级制造、材料和加工方面的进一步重大创新成为可能。
