Introduction

The ability to design, manipulate and validate the crystal chemistry of materials is fundamental to materials science. This course will provide students with the strategies and tools to rationally tailor functional materials. Formal descriptions of plane and space symmetry will be introduced and the imposition of chemistry on these mathematical precepts explained. The compilation of key crystal structure families and the derivation of complex structures from simple prototypes will systematize the most common materials encountered. Responses of crystals to pressure, temperature and chemical composition are explored. Mechanisms for introducing nonstoichiometry are classified and common extended defect described. The role of nonstoichiometry in controlling functional materials properties will be illustrated for galvanic cells, sensors, catalysts and environmental remediation.
