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.
