#### APPLIED PHYSICS 499 – Independent Study

To do an independent study, you will register for APP PHYS 499: Independent Study, with the independent study instructor's section number (see below for section numbers). You must first get permission from the instructor.

#### APPLIED PHYSICS 501-1 – Faculty Research Seminar

Seminars presented by faculty in the Applied Physics Graduate Program describing ongoing research.

#### APPLIED PHYSICS 590 – Research

During your first eight quarters, when you are not taking at least three courses (i.e. during summers and your second year), you will register for APP PHYS 590: Research, with your advisor's section number (see below for section numbers). Register for 590 with as many units as you need to add up to a total of three units.

#### GEN ENG 519 – Responsible Conduct of Research Training

Should be taken in the first year. The goal of Responsible Conduct of Research (RCR) training is for anyone involved in research to perform the most ethical research possible. Northwestern University has in place a number of policies that clearly demonstrate our commitment to research integrity. Collectively, these apply to all members of Northwestern's research enterprise: students/trainees, staff and faculty.

#### MAT SCI 401 – Chemical & Statistical Thermodynamics of Materials

The following topics in classical thermodynamics will be covered: the laws of thermodynamics; conditions for equilibrium; solutions; excess quantities; binary and ternary phase diagrams. Additionally, the following topics in statistical thermodynamics will be covered: statistical definition of entropy; ensembles and the Boltzmann and Gibbs distributions; quantum and classical ideal gasses; and the regular solution model.
