Ultrastructure Processing and Environmental Stability of Advanced Structural and Electronic Materials
Abstract
The goals of this Multi-Investigator Research Program (MIRP) are: (1) achieve an understanding of the science of ultrastructure processing, and (2) apply the science of ultrastructure processing to produce new optical, electronic, optoelectronic, and structural materials. Ultrastructure processing refers to the manipulation and control of chemistry based processes to attain a new generation of high performance materials. Problem areas to benefit from ultrastructure processing include: advanced optical and opto-electronic systems, non-linear optical matrices, laser hosts, controlled particulates, transpiration cooled optics, effects of energetic particle beams, electronic behavior of high band gap semiconductors. Six projects are pursued. A cumulative list of the 60 papers published and 11 patents submitted during this contract is presented. A few papers from each project published during 1991-92 are presented. Project A: Sol-Gel Processing Science. Three papers describe the physical chemical factors and structural evolution and characterization of the sol-gel processing of large Si02 monoliths. Real time monitoring of the drying behavior of large silica gels is reported. A third paper reports on sol-gel derived titania-silica glasses with FTIR and structural characterization. glass, surfaces, optics, ultrastructure, infrared reflection spectroscopy, microstructure, gels, gel- glass transformation, processing, composites, silica, noise, powders, superlattices, metal organic precursors, drying, thermal.
