Thrust Groups There are six multidisciplinary thrust groups working in the Center: 1. The Charge Transport and Structure group, which is performing research on electrically conducting polymers with the goal of discovering new materials for batteries, electrical detectors, or integrated circuits. 2. The Interfaces group, which is synthesizing artificially s t r u c t u r e d materials whose properties have never before been produced. Some of these materials have unusual strength and stiffness properties; others have unique combinations of electrical and magnetic properties. 3. The Ceramics Processing group, which is searching for a superior way to make advanced oxides such as high temperature resistant ceramics. 4. The Fatigue of Metalsand Alloysgroup, which is studying how metals lose their strength over time while being subjected to constantly varying stresses. 5. The Magnetism: Phenomena and Materials group, which is studying magnetic and superconducting materials. 6. The Nonlinear Optical Polymers group, which is formulating polymers that are able to double or triple the frequency of light passing through them.
nonmetallic materials are stable, inexpensive, and have many possible uses. The reasons stress-cracks in materials grow faster if they are short instead of long has been studied by the Fatigue of Metals and Alloys group. They have even developed a formula for the conditions under which a short crack will not grow. In other research, this group has pursued the development of high-temperature failure-resistant alloys. Research on artificially structured materials having novel, never encountered, and potentially useful characteristics is carried out by the Solid-Solid Interfaces group. Their pioneering efforts have opened the new field of compositionally modulated structures. The Ceramics Thrust group has studied sintering, grain growth, mass transport, grain boundary, and near-boundary defect structures in a model material, extending the results to other technologically interesting materials. This group's goal is to further our understanding of the fundamental factors that affect the ultimate densification of ceramic materials.
Research Accomplishments The Materials Research Center has reported several significant research accomplishments. These include in recent years the preparation of a new class of electrically conducting organic compounds by the Charge Transport group. These synthetic,
