ABSTRACT EEC-9526685 Burgess This award provides funding for a "TIE" project to pursue cooperative research in the application of acoustics for characterization of gas and liquid phase inclusions in systems of interest to the NSF I/UCRC for Separations Using Thin Films at the University of Colorado (CSTF) and the Center for Process Analytical Chemistry (CPAC) at the University of Washington. The proposed "TIE" project research represents the first step in an anticipated long-term collaboration towards the development of a new generation of smart sensors. The specific research objectives involve the adaptation of acoustic time-domain reflectometry to the study of changes in the pore structure which occur during membrane compaction and changes in bubble size and position which occur in process streams. An improved fundamental understanding of these phenomena is essential for successful development of membrane-based chemical sensors. The proposed research builds upon existing strengths in acoustics and membranes at CSTF and expertise in chemistry and chemical processing at CPAC, and makes effective use of costly resources by designing and fabricating sophisticated acoustic instrumentation that can be applied to both membrane compaction and bubble dynamics. In addition, the creation of a formal "TIE" between the relatively young CSTF and well-established and highly successful CPAC will enable CSTF to obtain valuable information from CPAC about long-term sponsor development and facilitation of technology transfer with industry sponsors.

摘要 EEC-9526685 Burgess 该奖项为一个“TIE”项目提供资金，该项目旨在开展合作研究，应用声学技术对科罗拉多（CSTF）的NSF I/UCRC使用薄膜分离和华盛顿大学的过程分析化学中心（CPAC）感兴趣的系统中的气相和液相夹杂物进行表征。 拟议的“TIE”项目研究代表了预期的长期合作的第一步，以开发新一代智能传感器。 具体的研究目标涉及声学时域反射法的适应性，以研究膜压实过程中发生的孔结构变化和工艺流中发生的气泡大小和位置变化。 对这些现象的基本理解的改进对于基于膜的化学传感器的成功开发是必不可少的。 拟议的研究建立在现有的优势，声学和膜在CSTF和专业知识在化学和化学处理在CPAC，并有效地利用昂贵的资源，通过设计和制造复杂的声学仪器，可应用于膜压实和气泡动力学。 此外，在成立时间较短的服务运营基金与历史悠久和非常成功的CPAC之间建立正式的“TIE”，将使服务运营基金能够从CPAC获得有关长期赞助商发展和促进与行业赞助商进行技术转让的宝贵信息。
