Engineering Research Equipment Grants: Fourier Transform Infrared Spectrophotometer

鲍德温研究综述：这是一项工程设备赠款。傅里叶变换红外光谱仪将被化学、物理和化学工程系的一个用户组用于广泛的主题研究。将使用仪器的具体项目的示例如下。在掠射角镜面反射模式下，利用傅里叶变换红外光谱研究了金属/电解液和金属/聚合物界面的相互作用。第二个项目将使用该仪器检查催化剂表面的吸附物种。另外两个项目将利用该仪器纳入光声FTIR的能力，以识别和分析聚合物/颜料的交联机制，并为反应性相关利用的目的对煤和煤液化残渣进行表征。该仪器还将应用于正在研究非晶硅半导体合金结构性质的研究项目，以及只需要对复杂混合物和纯化合物进行常规化学分析的一些项目。利用该仪器的概念是围绕灵活的、多用户的园区研究资源，而不是专门用于任何单个项目或计划的仪器。新颖性/创新性：提案中描述的每个单独的研究项目都有自己的新颖性和创新性特征。作为这方面的例子，用FTIR研究聚合物/颜料相互作用可以检验这些机理

BALDWIN Research Summary: This is an Engineering Equipment Grant. The Fourier Transform Infrared Spectrophotometer will be used for research on a broad range of topics by a user group from the departments of Chemistry, Physics, and Chemical Engineering. Examples of the specific projects where the instrumentation will be used are as follows. The interactions which exist at metal/electrolyte and metal/polymer interfaces will be probed using the FTIR in the grazing angle specular reflectance mode. A second program will employ the instrument for examination of adsorbed species on catalyst surfaces. Two additional projects will take advantage of the ability of this instrument to incorporate photoacoustic FTIR for identification and analysis of polymer/pigment crosslinking mechanisms and for the characterization of coal and coal liquefaction residues for purposes of reactivity correlation utilization. The instrument will also find application in a research project where the nature of the structure of amorphous silicon-based semiconductor alloys is being investigated, as well as in a number of projects where only routine chemical analysis of complex mixtures and pure compounds is required. The concept for utilization of the instrument is centered around a flexible, multi-user campus research resource rather than an instrument dedicated to any one single project or program. Novelty/Innovation: Each of the individual research programs described in the proposal has its own novelty and innovative features. As examples of this, the study of polymer/pigment interactions with FTIR permits examination of these mechanisms
