... the synthesis and processing of new materials the drive to reduced dimensionality and nanofabrication the inexorable march toward increasing complexity the foray of materials research approaches and techniques into soft condensed matter and biological arenas · the move from empiricism toward predictability in the simulation of materials properties and processes The Role of Materials in National Security: The Past, the Present, the Future More than 20 years of ceramic materials technology development for gas turbines has led to improved high-temperature ceramic materials, component manufacturing technology, design and life prediction methodologies, and ceramic integration experience for a variety of applications. Honeywell's ceramic development programs have accelerated commercialization of ceramics for industrial engines, aerospace applications, and hybrid vehicles.

... There are many exciting materials for the new millennium with potential roles in national security, including piezo materials, such as aluminum silicates and other smart materials, and catalytic systems for remediating environmental hazards. It will be critical to search for materials that can play a dual rolematerials with both military and commercial applications.
