This course provides a rigorous introduction to nanomaterials science and engineering.
The course focuses on the fundamental chemical and physical concepts important to
the field. The goal of the course is to enable students to read and understand basic
concepts prevalent in the “nano” literature, and to recognize the current issues facing
researchers in the field.
Course Outline:
