“…We have reported on the formation of organosilicon polymers from the gas phase by the continuous-wave CO, laser-induced decomposition of 1-methyl-1-silacyclobutane [6] or 4-silaspiro(3.4)octane 171. Pulsed C 0 2 laser-induced multiphoton dissociation of silane in the presence of methyl methacrylate [l 11 has also been reported.…”

The infrared multiphoton decomposition of silane in the presence of methyl acrylate, acrolein, allyl methyl ether, allyl acetate, methyl vinyl ether, and vinyl acetate results in the formation of various gaseous compounds and the gas-phase deposition of solid material on cold reactor surfaces. Both multistep molecular reactions between silylene and the oxygenated olefins and radical processes are thought to contribute to the formation of the solid deposit. The latter incorporates all the silicon of reacted silane, the structure of which is inferred from IR and ESCA analysis to consist of different siloxane units. 1015

“…The deposition of polymer thin films using light has been accomplished by photolyzing precursors in the gas phase above a substrate with pulsed lasers. An example of this is the photolysis of 1-methyl-1-silacyclobutane to form an organosilicon polymer (Pola et al 1988). The addition of SF 6 to the precursor gas was used as an "energy conveyer" to assist the energy transfer from the 10.6-m IR photons to the precursor.…”

EXECUTIVE SUMMARYThe overall goal of this study was to identify new high-flux solar photon (HFSP) processes which show promise of being feasible and in the national interest. Electric power generation and hazardous waste destruction were excluded from this study at sponsor request.Our specific objectives were: * to survey pertinent information bases; · to construct and assemble in prescribed electronic form a bibliography of relevant literature; * to prepare an initial list of potentially promising HFSP applications; to define a set of criteria for evaluating potential HFSP applications; * to carry out more detailed evaluations of some of the more promising applications; · to provide recommendations on HFSP process applications indicating special promise; * to discuss the status of current relevant research; and * to recommend research needed to advance basic understanding of HFSP applications and to further their potential for practicality.Our approach was to carry out the project with a core team of researchers providing expertise over a broad array of foundational topics, viz., chemical physics, optics, spectroscopy, photochemistry, high-temperature reactions, industrial chemistry, and chemical process engineering. Because of the wide range of scientific and engineering disciplines relevant to the study goals and the relatively short time available for the study, members of the core team carried out intense, round-table discussions with invited experts in a diverse sphere of pertinent disciplines, e.g., pure and applied optics, solar energy, furnace design, combustion, materials science and engineering, etc. Core team members conferred with experts at the Solar Energy Research Institute (SERI) (now known as the National Renewable Energy Laboratory, NREL) and the University of Chicago, and with participants in related studies being conducted by the National Academy of Sciences and SRI International, Inc. PC-compatible software was used to carry out an in-depth survey of post-1985 literature and to assemble in electronic form a bibliographic data base of important publications. Our approach emphasized the importance of delineating critical scientific and engineering foundations for identifying, evaluating, and discriminating among potentially promising options for HFSP applications. For example, limitations on solar photon intensity and wavelength and temporal variations in solar insolation impact process capacity, duty cycle, and controllability. Competition from alternative sources of intense photon fluxes was also considered in some detail. Formal economic and engineering cost estimates were outside our charter, but the study noted the importance of considering both conventional and externalized factors (e.g., environmental impacts, national security, global competitiveness, quality of fossil or other energy displaced) in determining overall costs of HFSP and competing options.Our overall conclusion is that there is promise for new applications of concentrated solar photons, especially in certain aspects of ...
