COURSE DESCRIPTION
During this course we will discuss how elements can be combined to produce noncrystalline and crystalline solids with specified properties in order to understand the links between chemical bonding, crystal structures and physical properties. We will also specify the defect structure, the microstructure, and the mesoscale structure of materials, such as metals, ceramics and polymers.

Supplementary Textbook
Structure and Bonding in Crystalline Materials

GRADING
Homework
Four homework sets will be assigned and graded. The purpose of the homework is to aid
in learning the material. To this end, some collaboration among students in preparing the
homework is acceptable. However, in the main, the work should be primarily yours.
Because of this tight timeline, late homework will not be accepted.
Exams
There will be two examinations: midterm and a comprehensive final. There will be some separate questions for Undergraduates and Graduates.
Grading
Homework is 35%, Midterm is 30%, Final is 35%
