Acquisition of a Visible/Near-IR Raman System

小行星9704127 该奖项为特拉华州大学材料科学、化学工程和化学系购买新的拉曼系统提供了部分支持。 该拉曼仪器利用高灵敏度的电荷耦合器件（CCD）来检测从所研究的材料散射的激光。 为了能够研究从催化剂到聚合物的大量材料，输入激光激发必须从可见光到近红外区域（532 - 538）变化。950. nm.）。 因此，该拉曼系统将包括倍频二极管泵浦Nd：YAG激光器，其将用于一起泵浦可调谐固态Ti：Sapphire激光器，这将提供研究所有三个部门中感兴趣的问题所需的大范围波长。 该仪器将被研究人员用于先进材料设计和表征的许多不同领域。 这些包括用于化学分离的高表面积材料、过渡金属氧阴离子催化剂、金属基底上的有机自组装单层、微乳液、高温超导体、聚合物和离聚物。 这个拉曼系统将作为材料研究的焦点，汇集了一个多学科的研究小组，他们有一个共同的目标-了解先进材料的结构/性能关系。 这种仪器在材料科学系在特拉华州大学的存在将有助于促进校园内不同的研究小组之间的互动和合作，但同样重要的是，它也将促进工业互动/协作在特拉华州更全球性的材料社区。 一些小公司已经表示有兴趣探索使用拉曼光谱学在材料表征的过程监测模式，一种能力，可以与光纤探头实现。 有限的可行性研究可以在大学进行拟议的拉曼仪器。 该仪器也将被用作材料表征的一个更大的课程的一部分，这是所有研究生追求材料科学的高级学位所需的。 此外，它还将用于培训化学工程、物理和化学方面的学生，因为这些部门目前正在进行大量的材料密集型工作。 ***

9704127 Rabolt This award provides partial support for the acquisition of a new Raman system for the departments of Materials Science, Chemical Engineering and Chemistry at the University of Delaware. The Raman instrument utilizes a high sensitivity Charge Coupled Device (CCD) for detection of the laser light scattered from the materials under investigation. In order to be able to investigate a large collection of materials ranging from catalysts to polymers, the input laser excitation must be varied from the visible to the near infrared region (532.-950. nm.). Hence this Raman system will include a frequency-doubled diode pumped Nd:YAG laser which will be used to pump a tunable solid state Ti:Sapphire laser together which will provide the large range of wavelengths needed to study the problems of interest in all three departments. The proposed instrument will be used by researchers in a number of different areas of advanced materials design and characterization. These include high surface area materials used for chemical separations, transition metal oxygen-anion catalysts, organic self-assembled monolayers on metallic substrates, microemulsions, high temperature superconductors, polymers and ionomers. This Raman system will serve as a focal point for materials research, bringing together a multidisciplinary group of researchers who have a common goal-to understand the structure/property relationships in advanced materials. The presence of such an instrument in the Materials Science Department at the University of Delaware will serve to facilitate interaction and collaboration between the different research groups on campus but, just as importantly, it will also promote industrial interaction/collaboration in the more global materials community in Delaware. A number of small companies have expressed interest in exploring the use of Raman spectroscopy in the characterization of materials in a process-monitoring mode, a capability which could be acc omplished with fiber-optic probes. Limited feasibility studies could be conducted at the university with the proposed Raman instrument. This instrument will also be utilized as part of a larger course in materials characterization which is required for all graduate students pursuing an advanced degree in materials science. In addition it will be used to train students in chemical engineering, physics and chemistry because of the large amount of materials-intensive work that is currently being carried out in those departments. ***
