Learning in Chem 448
There is a tremendous amount to learn in this field and in this course. Several scientific communities include areas of surface chemistry, but speak largely in different languages. These fields include chemistry, physics, biology, electrical engineering, chemical engineering, and bioengineering. Our goal is to give you enough background (and language training) to understand current research in these areas through talks and papers. This will require a great deal of work on your part.
Anticipate that the lectures, the readings, and the homeworks will be complementary rather than overlapping. You will be responsible for the material from all of these sources. Similarly, your participation in class is required both for discussions and for the education of your classmates and professors. There is nothing that we plan to say that is so critical that a good classroom discussion would not be preferable.
This is a very dynamic subject with rapidly changing perspectives and many advances. You will learn about these by pointers to the current literature and by taking advantage of the many seminars in this field available at Penn State throughout the semester and beyond.
