REPORT


The Spring MRS Meeting returns to San Francisco this year, where it will stay for the decade. While the location is set, the program continues to grow and change. This year's program includes 26 symposia and has 2,400 oral and poster presentations planned, substantially more than any previous spring meeting. A cluster of symposia will address environmental concerns. One symposium covers recycling of wood-based materials, encompassing recycling paper, removing ink and contaminates, and creating composite structures using recycled fiber. The second symposium of this cluster covers materials for alternative energy sources, such as chemically selective membranes and catalysts, and materials for hightemperature and high-pressure energy conversion. The third symposium addresses materials separation using membranes, zeolites, etc. to handle toxic waste, remove metals, or filter gases. Fullerenes, fullerides, and fulleroids settle into a symposium on novel forms of carbon, joined by diamond films, carbon clusters, fibers, amorphous carbon, graphite, extraterrestrial carbon, and foams, bringing together diverse interests but focusing on a common element. The largest symposium will consider "better ceramics through chemistry." As science looks to build unique materials from the atom up, more attention is focusing on the versatility and insight gained through chemistry. A symposium on "smart materials" and micro-electro-mechanical systems teases the imagination with a vision of tiny modern machines performing tasks by sensing and responding to light, chemistry, temperature, and even biological stimuli.

As computers grow in complexity and capability, so too do computational methods to explain and predict structure, properties, and other materials phenomena. A symposium addressing computational methods will cover modeling of polymers, ceramics, superconductors, interfaces, clusters, processing, and more. Semiconductors are broadly represented in a series of symposia, including two new ones on photo-induced space charge effects and defect engineering. Additional symposia cover surface preparation, reliability, metallization, heteroepitaxy, beam interactions, and electronic packaging. Among other intriguing topics is one within the symposium on art and archaeology. Several sessions address the destruction of cultural property and historic monuments resulting from armed conflict and the conservation science required to preserve them. Examples draw from World War I and II, the Persian Gulf War, and recent conflicts surrounding Yugoslavia. Other symposia cover microwave processing, dusters and colloids, aerosols, intermetaUic matrix composites, submicron multiphase materials, defects in oxides, and macromolecular host-guest complexes. See the matrix on the following pages for a list of all the technical symposia and session titles.

Special Features The plenary speaker on Monday night will be Bassam Z. Shakhashiri, professor of chemistry at the University of WisconsinMadison. Shakhashiri founded the University of Wisconsin's Institut
