SBIR Phase I: On-Line, Non-Destructive, Rapid Characterization of Nanopowders and Agglomerates

9960509 Manickavasagam这个小型企业创新研究第一阶段项目测试了使用偏振光散射来表征纳米粉末大小和形状的可行性。纳米结构是一种新的材料家族，它允许定制结构、电化学、电学、电子、光学、磁性和化学性质。纳米材料发展成为有用的设备和产品在很大程度上取决于在合成、加工和设备生产过程中对这些材料进行表征的能力。目前的表征技术离线、缓慢、昂贵且不可靠。协同技术公司(STI)将开发一种创新的在线、可靠、信息丰富和实时的设备。该系统的前驱体已成功地用于表征燃烧过程中产生的纳米碳烟单体的团聚。任务包括准确评估和表征各种单个纳米粉末及其凝聚体。STI咨询了纳米材料领域的两家领先的商业创新者：Triton系统公司和纳米材料研究公司。这些公司对STI的技术非常感兴趣，并渴望帮助他们开发用于在线商业用途的系统。第一阶段的工作将集中在概念验证上，重点是表征纳米粉末团聚的结构。第二阶段将涉及建立和集成原型装置，以便在生产设施进行在线测试。

9960509ManickavasagamThis Small Business Innovation Research Phase I project tests the feasibility of using polarized light scattering for characterization of nano-sized powder size and shape. Nanostructures are a novel family of materials that allow customized structural, electrochemical, electrical, electronic, optical, magnetic, and chemical properties. The development of nanomaterials into useful devices and products depends in large part on the ability to characterize these materials during synthesis, processing, and device production. Current characterization techniques are off-line, slow, expensive, and unreliable. Synergetic Technologies, Inc. (STI) will develop an innovative on-line, reliable, information-rich and real-time device. A precursor of the proposed system has been successfully used to characterize agglomerates of nano-sized soot monomers from combustion processes. Tasks include accuracy assessment and characterizing a variety of individual nanopowders and their agglomerates. STI has consulted with two leading commercial innovators in the nanomaterials area: Triton Systems and Nanomaterials Research Corporation. These companies have great interest in STI's technology and are eager to assist them in developing a system for on-line commercial use.Phase I efforts will focus on proof-of-concept, with special emphasis directed atcharacterizing the structure of nano-powder agglomerates.Phase II will involve building and integrating a prototype unitfor on-line testing at a production facility.
