2002 MRS Spring Meeting Integrates Soft Materials with Traditional Research More than 2400 scientists gathered at the 2002 Materials Research Society Spring Meeting, held April 1–5 at the San Francisco Marriott and Argent Hotels in San Francisco. Along with the 23 technical symposia, meeting chairs Zhenan Bao (Bell Laboratories/Lucent Technologies), Eugene A. Fitzgerald (Massachusetts Institute of Technology), Ulrich M. Gösele (Max Planck Institute for Microstructure Physics, Halle), and Kenneth P. Rodbell (IBM T.J. Watson Research Center) treated attendees to special events covering homeland security, venture capital—getting science to the marketplace, and, most popular, the history of wine. At the plenary session on Wednesday evening, J. Hendrik Schön (Lucent Technologies) received the Outstanding Young Investigator Award and Jeff Wadsworth (Lawrence Livermore National Laboratory) gave the plenary address on science and technology and counterterrorism. Organic materials and biological connections are increasingly integrating into the mix of rapidly developing areas in materials research. In addition to the common strength in electronic and optoelectronic materials, the meeting included a cluster of five symposia on molecular and biomaterials, along with coverage of flexible substrates for electronics, polymer nanocomposites, and bioMEMS. Areas such as microfluidics rely on MEMS technologies to interface with biological-scale flow. Organics are leading to low-cost, large-area electronics and photovoltaics as functionally useful materials that can be processed inexpensively. And while materials research has not made a major course change following the September 11 attacks, several special sessions relating to security and counterterrorism point to the materials challenges of biosensors.

Electronic and Optoelectronic Materials Symposium D on perovskite materials represented the interdisciplinarity that is the hallmark of MRS meetings and symposia. To an audience of materials scientists, R. Jeanloz (UC—Berkeley) gave an earth scientist’s perspective on perovskite materials as he discussed the properties of silicate perovskites relevant to the earth’s mantle. To simulate the high pressures found in the earth’s interior, diamond anvil cells are used along with facilities such as synchrotron radiation sources. Jeanloz said that (Mg,Fe)SiO3 perovskite makes up 70–90% of the deep mantle, which corresponds to 40% of the planet. While the deep mantle cannot be directly sampled, acoustic measurements during earthquakes, for example, provide a great deal of information about its composition and structure. Several talks within Symposium E focused on nanostructural magnetic materials for data storage. One was by K. Krishnan (Univ. of Washington) on assembly techniques and shape control of Co nanocrystals, as they are being touted as a potential data-storage material. Co nanocrystals were synthesized by the injection of a precursor into hot coordinating solvent followed by growth. The nanocryst
