Equipment Proposal for Acquisition of Low Angle Light Scattering Equipment

这笔拨款用于购置一台Ar离子激光器和一台小角度光散射测角仪，以完成一台能够定量测量0.5度至20度散射角的激光光散射光谱仪。建成后，该光谱仪将用于研究：1。醇和羧酸溶液中的扩散和氢键。2.有机金属(硅、锗等)酯的水解和溶胶化动力学3.硅油/非离子表面活性剂/水微乳液的表征4.胶体颗粒聚集和破碎的动力学。5.可用作聚合物溶液、陶瓷粉末合成和包覆酶反应研究的分析工具的其他项目。光散射光谱学在处理胶体现象的许多工程方面正成为越来越必要的工具。其中最重要的是在先进、高性能材料的制造过程中发生的过程，其中包括陶瓷、复合材料和电子材料，这些过程受到对该设备的收购的影响。

This grant is for the acquisition of an argon ion laser and a small angle light scattering goniometer to complete a laser light scattering spectrometer capable of making quantitative measurements from 0.5 degrees to 20 degrees scattering angles. When completed the spectrometer will be used to study: 1. Diffusion and hydrogen bonding in solution of alcohols and carboxylic acids. 2. Kinetics of hydrolysis and sol formation by organic esters of metals (silicon, germanium, etc.) 3. Characterization of silicone oil/nonionic surfactant/water microemulsions. 4. Kinetics of colloidal particle aggregation and breakup. 5. Other projects in which it can be used as an analytical tool in studies of polymer solutions, ceramic powder synthesis, and encapsulated enzyme reactions. Light scattering spectroscopy is becoming an increasingly necessary tool in many aspects of engineering which deal with colloidal phenomena. Among the most important, which is affected by the acquisition of this equipment, are processes which occur in the manufacturing of advanced, high performance materials, including ceramic, composite, and electronic materials.
