lecular reaction products produced by combustion, separation and recombination of atoms subjected to shock impacts, and the monitoring of atomic interactions on a femtosecond scale. The session on fullerene materials spans that topic from superconducting to endohedral and higher fullerenes. It includes nanotubes—tiny carbon cylinders, recently produced in gram quantities, which have spurred the imagination of researchers and engineers, inspiring them to dream up electrically and mechanically versatile nanocomposites. The symposium on nanocomposites and nanophase materials will cover everything from ceramics with better structural properties to luminescence of quantum confined silicon crystallites and intercalated nanocomposites. A large portion of the symposium on microcrystalline semiconductors delves into the issues that still confront scientists working on porous silicon. For example: for reasons that are still puzzling, the interesting properties of porous silicon rapidly degrade while the material is being processed. The symposium on atomic-scale imaging of surfaces and interfaces will tour the
atomic world. Videos will demonstrate how atoms and molecules can be manipulated and chemical reactions controlled with the scanning tunneling microscope, and will show high resolution TEM of silicides forming and phases separating. Photoelectron diffraction holography, used to image atoms and magnetic moments near surfaces, will be discussed. The symposium on evolution of surface and thin-film microstructure will hold four short afternoon panel discussions, each giving multiple views on a particular topic. The panel discussions will be based on results from a variety of analytical techniques probing surface roughness of heterostructures, CVD growth kinetics, misfit accommodation, and surface diffusion mechanisms. Other symposia will cover superconductivity, beam-solid interactions, stability of microstructures, semiconductor heterostructures, chemical perspectives of microelectronic materials, laser ablation, silicon nitride ceramics, small confining systems, materials theory and modelling, disordered systems, solid state ionics, intermetallics, nuclear waste, and suspensions. For a list of all the technical symposia and session titles, see the matrix on the following pages.
Special Features John A. Armstrong, IBM vice president, science and technology, will give the plenary address on 'The Changing Role of Research Both in Industry and the University." His Monday evening address will focus on the end of the Cold War and the related emergence of high technology competition on a global scale, and the reappraisal of the role of research establishments both in industry and in universities. The Von Hippel Award ceremony and lecture will be given Wednesday evening, along with the presentation of MRS Medal Awards and Graduate Student Awards. At noon on Tuesday, in Symposium X, the first Turnbull Award Lecture will be given by Thomas R. Anthony, a physicist at General Electric and a world leader in low pressure metastable d
