This statement reflects the recognition by members of the chemical communitv t h a t materials chemistrv-the chemistry of polymers, Jemiconductors, superconductors. advanced metal allovs, and biorompatible materials, to cite a few examplesihas become a n important compon& of our discipline. The Ad ~ o Committee c for Solid-state Instructional Materials was or~anizcdin 1990 to helo revitalize introductory chemist&courses by mainstreaming materials chemistry into the curriculum.7 I n order to accomplish this objective, the committee recognized the need to demystify 'Department of Chemistry, University of Wlsconsin-Madison, Madison, Wi 53706 'Department of Chemistry, Rutgers University, New Brunswick, NJ

the jargon of materials chemistry, much of which is derived from engineering, physics, and materials science; to make the extended three-dimensional structures of solids comprehensible; and to gather examples of contemporary materials and their applications. The high-tech materials and advanced devices associated with current research and everyday experiences require only a modest background in solid-state chemistry and can add a sense of relevance and excitement to the course. The committee has undertaken the preparation of instructional materials leading to this more balanced approach to introductory chemistricourses with support from the National Science Foundation (Undergraduate Course and Curriculum Program) and the Camille and Henry Dreyfus Foundation. Our stratem for mainstreaming materials chemistm is based on demonstrating how solizs can be used to ill'trate virtually every topic typically discussed in an introductory chemistry cmn-ie. G o examples are the exquisite atomic images obtained in scanning tunneling microscopy studies of layered solids like graphite and the preparation of high-temperature superconductoring oxides through the application of stoichiometric principles. Empowered in this manner, chemistry teachers can seamlessly use materials chemistry examples in their introductory chemistry courses a s they best see fit. To facilitate this "technology transfer", the committee is writing A Materials Chemistry Companion to General Chemistry, which is scheduled to be published by the American Chemical Society in mid-1993. The Companion will be organized around traditional tooics for use in eonventionalcourse structures. In additidn, the volume will have a matrix that correlates standard topies with particular kinds of materials and their applications, permitting the book to be used to supplement nontraditional course presentations, as well. The Companion is for teachers: I t will serve a s a n introduction to materials chemistm as well a s a source of exercises, demonstration and laboratory experiments, and supporting instructional materials (kits and software, for example). Examples of Companion-related instructional materials include a n Optical Transform Kit that demonstrates how diffraction is used to reveal relative atomic positions (2);'a Crystal Structure Model Kit that permits construction of nearly 60 common crystal ~tructures;~"memory metal", an example of a "smart" material t h a t illustrates phase changes in solids;1° light-emitting diodes (LEDs), which highlight periodic properties, substitutional stoichiometry, and spectroscopy (3); and ferrofluids, which demonstrate cou~erativeelectronic effects. 1; order to make the Companion as user-friendly a s possible. we have invited institutions to field-test material to be incorporated into the volume. If you are interested in auditioning instructional materials from the Companion, please contact the authors for additional information.
