CEM-913 Spring 1999

MICHIGAN STATE UNIVERSITY

DEPARTMENT OF CHEMISTRY

Spring Term 1999

 

COURSE Special Topics in Inorganic Chemistry: Solid State Chemistry and Its Applications

INSTRUCTOR Mercouri G. Kanatzidis, Room 406 Chemistry.

SCOPE AND PURPOSE: This is a descriptive course designed to introduce the students to the fundamentals of solid state chemistry as well as recent developments in this important area of chemistry.

TEXT a) a) Solid State Chemistry and Its Applications, by A West

b) Lectures on the electrical Properties of Materials, by Solymar and Walsh.

c) Solids and Surfaces: A Chemist's View of Bonding in Extended Structures by Roald Hoffmann, 1988 VCH Publishers Inc.

The above textbooks will act as guides in teaching fundamental solid state chemistry concepts and techniques. The course will also make use of original literature and review articles. A number of books and monographs (from which I would be drawing teaching material), will be reserved in the library. In some lectures, copies of original literature articles will be handed out.

LECTURES Tuesdays and Thursdays 1:50-3:20 pm Room 339
