该合同将为凯斯西储大学大分子科学系的一个新设备的开发提供部分支持，该设备用于测量聚合物材料中的单组分和多组分气体/蒸汽传输。该设施将成为新的“气体渗透、分离和屏障实验室”的核心。将购买一些商业和仪器，用于准确和常规的氧气，二氧化碳，水和香气的渗透测量。这些仪器将用于大分子结构的精确和常规表征。此外，将设计和建造一个具有质谱检测的通用扩散装置，能够在广泛的压力和温度范围内测量单组分和多组分气体/蒸汽输运，用于玻璃状和半晶体聚合物的扩散机制和固态结构的基础研究。最后，通过将商用香气传输装置与配备低温捕获的气相色谱仪和质谱检测器的状态联网，可以实现香气和风味的多组分传输的准确分析。该中心将加强凯斯西储大学大分子科学系和其他系之间的合作，如化学工程、生物医学工程、化学、物理和医学。合作研究领域将涉及聚合物中小分子运输的基础科学，并探索新材料概念，从而开发新的屏障系统和结构。该设施将通过对研究生和本科生的基础研究培训以及在一般实验室课程中的使用，对凯斯西研究大学的教育产生广泛的影响。该设施将有助于为我们的聚合物科学和工程培训带来新的跨学科和环境风味。该设施将显著加强合作研究和教育互动，并为学生和教师提供机会

9975774NazarenkoThis award will provide partial support for the development of a new facility in the Department of Macromolecular Science at Case Western Reserve University for measurements of single and multicomponent gas/vapor transport through polymeric materials. This facility will be at the core of new "Gas Permeation, Separation and Barrier Laboratory." Several commercial and instruments for accurate and routine permeation measurements of oxygen, carbon dioxide, water and aromas will be purchased. These instruments will be used for accurate and routine characterization of macromolecular structures. Additionally, a universal diffusion apparatus with mass-spectroscopic detection, capable of measuring single and multicomponent gas/vapor transport over a wide range of pressures and temperatures, will be designed and constructed for fundamental studies of diffusion mechanisms and solid state structure of glassy and semicrystalline polymers. Finally, accurate analysis of multicomponent transport of aromas and flavors will be achieved by networking a commercial aroma transport device with a state of the are gas chromatograph equipped with cryogenic trapping and an MS-detector.The facility will enhance the collaborations among researchers in the Department of Macromolecular Science and other departments of Case Western Reserve University such as Chemical Engineering, Biomedical Engineering, Chemistry, Physics and Medicine. The areas of collaborative research will address the fundamental science of small molecule transport in polymers and also explore new materials concepts leading to the developing of new barrier systems and structures. The facility will have a broad impact on education at Case Western Research University through fundamental research training of graduate and undergraduate students and through its use in general laboratory courses. The facility will be instrumental in bringing a new interdisciplinary and environmental flavor into our polymer science and engineering training.%%%The facility will significantly enhance the collaborative research and educational interactions and opportunities for students and faculty.***
