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.

该奖项授予理哈伊大学化学系James E. Strum博士，以表彰他为化学、生物化学和化学工程专业学生提供的物理化学实验课程。该项目涉及课程开发和实验室改进仪器，并由化学部门支持。物理化学实验课程将被修改为强调“聚合系统”，其特点是分子或离子的集体行为。这样的系统范围从复合离子到宏观晶体，包括胶束、囊泡、胶体、颗粒悬浮液、液晶和膜。在过去的十年中，对这些系统的研究有了相当大的增长，这些实验的纳入将更新本课程，并延伸到其他大学的物理化学实验室。五个新的实验将发展：x射线衍射的分子晶体，液晶的相变，表面积的测定，脉冲光解和螺旋线圈转变。该奖项支持的仪器采购包括一个差示扫描量热计、一个表面积吸附仪和一个脉冲光解仪。
