Fabrication Of The Pewee Nozzle; Brazing Nozzles For Rockets Powered By Nuclear Reactors, William C. Turner
Fabrication Of The Pewee Nozzle; Brazing Nozzles For Rockets Powered By Nuclear Reactors, William C. Turner
Chemical and Biological Engineering ETDs
This thesis describes the steps taken to develop an improved process for brazing nozzles for nuclear-powered rockets. It defines the state of the art prior to this work. It gives an evaluation of the brazing alloys available for use. It shows the methods employed to develop the use of positive fixturing. It describes the use of full-scale sectors to refine processing. This thesis also describes the use of such new processing techniques in the successful production of two nozzles. Gold-nickel-palladium brazing alloys are used. Vacuum atmosphere performs superbly. Bands are used to hold U-tubes into slots in the shell. Problems …

The Synthesis Of Some New Azabenzo[A]Pyrene And Monomethyl Azabenzo[A]Pyrene Derivatives, Richard E. Phillips
The Synthesis Of Some New Azabenzo[A]Pyrene And Monomethyl Azabenzo[A]Pyrene Derivatives, Richard E. Phillips
Chemistry and Chemical Biology ETDs
The synthesis of six new azabenzo[a]pyrenes was undertaken in order that the carcinogenic and carcinostatic properties of these compounds might be tested. The compounds thus synthesized were 4-aza benzo[a]pyrene (1), 5-methyl-4-azabenzo[a]pyrene (2), 12-azabenzo[a]pyrene (3), 11-methyl-12-azabenzo [a]pyrene (4),5 -azabenzo [a]pyrene (5), and 4-methy1-5-azabenzo[a]pyrene (6).
Compounds 1 and 2 were prepared from the intermediate 4-keto-1,2,3,4-tctrahydrochrysene. The azine from this ketone was dehydrogenated and the resulting aromatic amine was both formylated and acetylated. The amides were cyclized with polyphosphoric acid in a Bischler-Napieralski cyclodchydration giving fair yields of 1 and 2. The synthesis of compounds 3 and 4 was carried out in a …
Paths Of Energy Degradation In Transition Metal Complexes, James N. Demas
Paths Of Energy Degradation In Transition Metal Complexes, James N. Demas
Chemistry and Chemical Biology ETDs
To elucidate the paths and rates of energy degradation in transition-metal complexes following photoexcitation, a comprehensive experimental study was carried out on a total of fourteen complexes of Ru(II), Os(II), Ir(III), and Rh(III). Photoluminescence lifetimes, spectra, wavelength dependences of the quantum yields, and absolute quantum yields were determined. The complexes all contained organic ligands—pyridine, 2, 2’bypyridine, 2, 2’ 2”-terpyridine, and 1, 10-phenanthroline. The ruthenium, osmium, and iridium complexes all exhibited charge transfer (CT) phosphorescences with quantum yields of 1-60% and lifetimes of 0.6-11 µsec in an alcoholic glass at 77°K. The rhodium complexes gave d-d* phosphorescences with yields in the …

Size Distribution Analysis Of Carbon Black By Andreason Pipette Method, Natarajan Mani
Size Distribution Analysis Of Carbon Black By Andreason Pipette Method, Natarajan Mani
Chemical and Biological Engineering ETDs
There have been several methods commonly used for measuring particle size distribution of particulate systems in the subsieve region, i.e., less than 45 microns. Of the many indirect procedures of particle size analysis, sedimentation methods are among the most satisfactory and most widely used. - The value and appeal of sedimentation techniques are twofold: (1) the equipment required is simple and (2) a wide range of sizes may be measured readily with considerable accuracy and reproducibility. These techniques utilize the dependence of the falling velocities of particles on their size.
This study widely encompasses the various factors involved in the …
