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.

Wednesday 13 October 1999 Class
Exam I
covering lectures, readings, and discussions through Surface Thermodynamics Lectures
in two formats: Word (doc) or Adobe Acrobat (pdf)
You should time yourself and take no longer than 90 minutes to do the exam.
Prepare your notes before you look over the questions!
You must turn it in by 5 PM on Friday 15 October to Dave Allara's or Paul Weiss's office.
Main topics on the exam:
Atomic and molecular views of surfaces and solids.
Thermodynamic views of surfaces (know the three important equations we discussed).
Proximal probes.
Expect an exam along the lines of our discussion questions and the open ended questions we ask in class. Know the fundamentals!
You may use any hand-written notes you like on the exam.
Instead of class, please attend Mark Reed's seminar at the Materials Research Lab (out Pollock Road, about three buildings past University Ave -- this is quite a hike, start early!).
Mark A. Reed, Department of Electrical Engineering, Yale University
