9623718 Baker By using diblock copolymers that can be selectively tailored to produce different packing densities on a surface, a wide regime of geometries can be prepared in good and poor solvents. The molecular details of these more realistic and useful sheared systems will be examined, paying particular attention to equilibrium geometries before and after subjecting them to shear stresses. %%% The teaching methods proposed are for an upper-level surface spectroscopy class to combine a more traditional lecture course with hypermedia techniques and interactive teaching styles with laboratory experiences. ***

通过使用二嵌段共聚物，可以选择性地在表面上产生不同的填充密度，可以在良好和恶劣的溶剂中制备广泛的几何形状。这些更现实和有用的剪切系统的分子细节将被检查，特别注意平衡几何形状之前和之后，使他们受到剪切应力。建议的教学方法是将较传统的讲座课程与超媒体技术相结合，并将互动教学风格与实验室经验相结合。＊＊＊
