An investigation of the fundamental chemistry of recently discovered gold-catalyzed oxidation/reduction reactions of organic and inorganic compounds with nitrogen dioxide and nitric acid is proposed. the redox reactions are important for new technologies, constituting the basis for selective and… More

The development of new selective detectors for gas and liquid chromtography for the sensitive measurement of sulfur-containing compounds is proposed. these detectors are basedon fluorine-induced chemiluminescence and are highly se selective for sulfides, disulfides and mercaptans. the majorresearch… More

The development and evaluation of new selective and sensitive detectors for gas chromatography is proposed. thisinstrumentation will be used for the direct analysis of organic compounds and for rapid screening for the presence of particular classes fo organic compounds. the detectors are based on… More

The development of a new detector for gas chromatography based on photochemical amplification is proposed. in the proposed system, the effluent of the gas chromatography mixed with a gas stream containing oxygen and enters a photochemical reactor. analytes which absorb uv radiation are quenched by… More

A novel technique for the preparation of thin films of the rare earth/barium/copper oxide superconductors is under development in this project. volatile fluorinated beta-diketonate metal chelates of eu, yb, ba, and cu will besynthesized and thin films of mixed metal oxides, e.g., euba(2)cu(3)o(7),… More

A new detector is under investigation for the measurement ofatmospheric sulfur compounds based on formation of sulfur monoxide with subsequent detection by ozone-induced chemiluminescence. this novel detection scheme for the measurement of gaseous sulfur compounds should offer many advantages over… More

The development of a system for the removal of organic compounds from a high purity water recycle system based on semiconductor catalyzed photo-oxidation is proposed. the combination of a semiconductor catalyzed photo-oxidation andion exchange resin will permit the development of a simple, compact… More

A new multidimensional technique for high-performance liquidchromatography (hplc) will be developed for the analysis of biological samples. in whole-column detection chromatography (wcdc), components of a complex mixture are detected simultaneously at multiple detection zones along the entire length… More

This phase i project involves the development of a rapid response atmospheric monitor for trace levels of gas-phase ammonia. the detector is based on the use of a metal oxide annular denuder tube for the collection of gaseous ammonia. when heated, this tube converts ammonia to nitric oxide which is… More
