This Small Business Innovation Research Phase II project is aimed at developing and demonstrating an innovative information-rich and real-time system for particle characterization. Encouraged by results from Phase I which established the feasibility of using polarized light scattering for characterization of micron, sub-micron and nano-sized ceramic particles, Synergetic Technologies proposes to develop an accurate and reliable on-line instrument. Phase I illustrated the high accuracy achievable, the ability to detect and quantify nano-size particles, and the capability of determining the size distribution of high aspect ratio whiskers and irregularly shaped particles. Project tasks include: system design, construction, calibration and testing; software development for more accurate shape determination and automized system use; study of different lasers; and testing and demonstration at three potential customer sites (a major ceramic research university, a large industrial research laboratory, and a small company at the leading edge of nanomaterials production). The University of Kentucky staff and students will assist in this project. The ability to measure fine particle sizes and shapes on-line is necessary for controlling the quality of many high technology products, such as advanced ceramics and pharmaceuticals. In addition, monitoring and controlling particle size is fundamental to the manufacture of many consumer products, medical products, food processing and environmental monitoring.

该小型企业创新研究第二阶段项目旨在开发和演示用于颗粒表征的创新信息丰富的实时系统。 第一阶段的结果确立了使用偏振光散射表征微米、亚微米和纳米尺寸陶瓷颗粒的可行性，受到该结果的鼓舞，Synergetic Technologies 提议开发一种准确可靠的在线仪器。 第一阶段展示了可实现的高精度、检测和量化纳米尺寸颗粒的能力以及确定高纵横比晶须和不规则形状颗粒的尺寸分布的能力。 项目任务包括：系统设计、构建、校准和测试；软件开发以实现更准确的形状确定和自动化系统使用；研究不同的激光器；在三个潜在客户地点（一所主要陶瓷研究大学、一个大型工业研究实验室和一家处于纳米材料生产前沿的小公司）进行测试和演示。肯塔基大学的工作人员和学生将协助该项目。在线测量细颗粒尺寸和形状的能力对于控制许多高科技产品（例如先进陶瓷和药品）的质量是必要的。 此外，监测和控制粒径对于许多消费品、医疗产品、食品加工和环境监测的制造至关重要。
