摘要CTS-9910162 Mallapragada，S. K.爱荷华州州立大学。该提案要求（支持作为主要研究者（PI）爱荷华州州立大学（美国）的（Surya）Mallapragada博士、伊兹密尔理工学院（土耳其）的Sacide Alsoy博士和Technion -以色列理工学院（以色列）的Joseph Miltz博士之间潜在三国合作努力的一部分的计划访视，致力于研究半结晶高分子包装材料的多组分干燥机理。 这项合作的想法诞生于美国国家科学基金会赞助的美国-以色列-土耳其三国会议期间，并在以色列海法举行（1999年3月）。 溶剂去除是包装材料的关键加工步骤，其中许多包装材料由半结晶聚合物制成。 因此，了解这一过程的机理对工业干燥过程具有重大影响。 这三位研究人员的专业知识在聚合物科学中的这个工业和基础重要问题上完美互补。 一个双管齐下的方法将被用来处理的问题，多组分干燥的半结晶聚合物在食品包装应用的背景下。 研究干燥条件对最终产品影响的实验方法将与数学建模相结合，以优化干燥条件和干燥机设计。 三名调查员有机会在以色列进行互动，并参观了现有设施。 然而，重要的细节仍需解决，调查人员也将从检查其他项目现场中受益匪浅。 因此，要求NSF提供支持，使PI能够访问土耳其的设施，并制定细节，以便三名研究者提交合作研究提案。

ABSTRACTCTS-9910162Mallapragada, S. K.Iowa State U.This proposal requests (support for a planning visit as part of a potential tri-national collaborative effort between the principal investigator (PI) Dr. (Surya) Mallapragada at Iowa State University (USA), Dr. Sacide Alsoy at Izmir Institute of Technology (Turkey) and Dr. Joseph Miltz at Technion - Israel Institute of Technology (Israel), devoted to investigating the multicomponent drying mechanism of semicrystalline polymer packaging materials. The idea for this collaborative was born during Tri-National US-Israel-Turkey sponsored by the National Science Foundation and held in Haifa, Israel (in March 1999). Solvent removal is a key-processing step in the case of packaging materials, many in which are made from semicrystalline polymers. Therefore, understanding the mechanism of this process has a significant impact on industrial drying processes. The expertise of the three investigators perfectly complement each other for this industrially and fundamental important problem in polymer science. A two pronged approach will be used to deal with the problem of multicomponent drying of semicrystalline polymers in the context of food packaging applications. Experimental approaches to investigate the effect of drying conditions on the final product will be complemented with mathematical modeling to enable optimization of drying conditions and dryer designs. The three investigators have had an opportunity to interact in Israel and tour the facilities available. However, important details still need to be resolved and the investigators would benefit greatly from inspecting the other project sites as well. Therefore, support is requested from NSF to enable the PI to visit the facilities available in Turkey and work out the details to enable a collaborative research proposal to be submitted by the three investigators.
