The project will develop a unified physical chemistry lab for the study of thermodynamics and kinetics in which some traditional as well as novel experiments are all related to nonequilibrium chemical self-organization. The Belousov- Zhabotinskii oscillating reaction will be the major focus. Students will study the phenomenology and dynamic behavior through "hands on" experiments via electrochemical techniques, calorimetry and video analysis (for the quantitative study of spatial phenomena). The polymerization of methacrylic acid will be studied with video analysis of propagating reaction fronts and viscometry of the product polymer. All experiments will use computer data acquisition with comparison to numerical models.

该项目将建立一个研究热力学和动力学的统一物理化学实验室，其中一些传统的和新颖的实验都与非平衡化学自组织有关。别洛索夫-扎博廷斯基振荡反应将是主要焦点。学生将通过电化学技术、量热法和视频分析(用于空间现象的定量研究)通过“动手”实验学习现象学和动态行为。甲基丙烯酸的聚合将通过对反应前沿的视频分析和产物聚合物的粘度计进行研究。所有实验都将使用计算机数据采集，并与数值模型进行比较。
