Mass-flow control system utilizing flow-feedback for gas chromatography

Creator:: Dodo, Gerald Haruo
Abstract:: A unique mass-flow control system for the carrier gas in gas chromatography is described and evaluated. Carrier gas flow is controlled by a flow sensor, feedback electronics, a flow-control valve and a microcomputer. The flow-rate is monitored by a mass-flow meter by this system and the flow is adjusted in...

Cyclization of organolithium and -zirconium compounds ; Rearrangements of selected anionic compounds in highly disassociative solvents

Creator:: Bass, Lawrence W.
Abstract:: Intramolecular cyclization of organometallic compounds represents a promising tool for synthesis. The reaction involves exothermic consumption of intramolecular double bonds via insertion into a carbon metal sigma bond. This represents an intramolecular example of the reaction type responsible for metal catalyzed polymerization of olefins. Organolithium reagents were found to cyclize...

Experimental and theoretical investigation of the ability of oxygen-containing molecules to accept charge

Creator:: Siggel, Michele Ruth Fisher
Abstract:: The question of why carboxylic acids and phenols are stronger acids than alcohols has been investigated experimentally and theoretically. The experimental approach involves comparison of gas-phase acidities and core-ionization energies. The theoretical treatment uses calculated point potentials and acidities. The ease of proton removal is related to two factors known...

Steroid dialkylcarbene reactions

Creator:: Dixon, Dale David
Abstract:: Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

The development of a high spectral-resolution laser-excited molecular fluorescence system and its application to gas chromatography and the determination of polynuclear aromatic hydrocarbons

Creator:: Hein, Scott J.
Abstract:: A high-spectral resolution laser-excited molecular fluorescence system was developed that utilizes a pulsed supersonic expansion to simplify the fluorescence excitation spectra of large, gas-phase aromatic molecules diluted in an excess of a monatomic gas. A microcomputer was used to control and synchronize the instrumental components, which included a Chromatix CMX-4...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...
