Laboratory Studies of Aggregated Systems: An Instrumentation and Curriculum Development Project

该奖项授予利哈伊大学化学系詹姆斯·E·斯特鲁姆博士，以表彰为化学、生物化学和化学工程专业学生提供的物理化学实验室课程。该项目涉及课程开发和实验室改进仪器，并得到化学司的支持。物理化学实验课程将被修改，以强调“聚集系统”，即以分子或离子的集体行为为特征的系统。这类体系的范围从络合离子到宏观晶体，包括胶束、囊泡、胶体、颗粒悬浮液、液晶和膜。在过去的十年中，对这种体系的研究有了很大的增加，纳入这些实验将更新这门课程，进而更新其他大学的物理化学实验室。将开展五个新的实验：分子晶体的X射线衍射、液晶中的相变、比表面积测定、脉冲光解和螺旋-线圈相变。该奖项支持的仪器采购包括差示扫描量热仪、表面积吸附仪器和脉冲光解设备。

This award to Dr. James E. Strum, Department of Chemistry, Lehigh University, is for enhancement of the physical chemistry laboratory course offered for students majoring in chemistry, biochemistry, and chemical engineering. The project involves both curriculum development and Instrumentation for Laboratory Improvement and is supported by the Chemistry Division. The physical chemistry laboratory curriculum would be modified to emphasize "aggregated systems", which are characterized by collective behavior of molecules or ions. Such systems range from complex ions to macroscopic crystals and include micelles, vesicles, colloids, particle suspensions, liquid crystals, and membranes. Studies of such systems have increased considerably in the past decade and inclusion of these experiments will update this course and, by extension, laboratories in physical chemistry at other universities. Five new experiments will be developed: X-ray diffraction by molecular crystals, phase transitions in liquid crystals, surface area determination, pulse photolysis, and helix-coil transition. The instrument acquisitions supported by this award are a differential scanning calorimeter, a surface area adsorption instrument, and a pulse photolysis apparatus.
