Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

Creator:: Zhang, Jie
Abstract:: In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

Water and methanol adsorption on a series of organic complexes of montmorillonite

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

Transition Metal Oxides for Aqueous Electrochemical Energy Storage

Creator:: Jiang, Heng
Abstract:: In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...

Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

Creator:: Wang, Yanli
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...

Creator:: Ruppert, John Fredrick
Resource Type:: Dissertation
Full Text:: variety of methods, and extension of these methods remains today an active area of endeavor (16-40). The

The system sulfuryl chloride-sulfur dioxide-chlorine. Equilibrium and catalysis kinetics studies

Creator:: Jischke, John Henry
Abstract:: A spectrophotometric study has been made of catalysis of the decomposition of sulfuryl chloride in carbon tetrachloride solution to an equilibrium mixture of sulfuryl chloride, sulfur dioxide and chlorine. The catalysts were activated charcoal, acetonitrile and 18-crown-6 polyether. A weak acetonitrile-sulfur dioxide complex also was established; formation constants found at...

The synthesis and valence isomerization of some para-substituted 1-phenyl-1,3,5-hexatrienes

Creator:: Platt, James LeGrande
Resource Type:: Dissertation

The synthesis and characterization of novel materials for use in secondary lithium-ion batteries

Creator:: Nafshun, Richard L.
Resource Type:: Dissertation

The study of fluo-tantalum species by solvent extraction

Creator:: Coker, Marjory Carol
Abstract:: The extraction of tantalum fluoride complexes by large cationic extractants (tetraphenylarsonium ion, TPA, and crystal violet) and by methyl isobutyl ketone (MIBK) has been investigated as a function of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the cationic extractants into chloroform were carried out in the absence of...
