Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

Creator:: Han, Fangyuan
Abstract:: In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...

Development, validation and the application of a congener specific photodegradation model for PBDEs

Creator:: Zeng, Xia
Abstract:: The thermodynamic properties of 39 PBDEs have been calculated using Gaussian 03 on the B3LYP/6-31G(d)//B3LYP/6-31G(d) level. The PBDE congeners' enthalpies of formation increase with increasing number of bromines and show a strong dependence on the bromine substitution pattern. The effects of bromine substitution pattern have been quantitatively studied by GAM...

Target fragmentation in the interaction of relativistic heavy ions and protons with ¹⁸¹Ta

Creator:: Oertel, Christopher Paul
Abstract:: The production cross sections for a number of target fragments formed by the reactions of 42- and 21- GeV²⁰ Ne and 28 GeV p with ¹⁸¹Ta have been measured. The target fragment radioactivities were measured by off-line gamma-ray spectroscopy. Details of the measurement as well as the calculation of the...

Novel monolithic columns for microscale liquid chromatography and capillary electrochromatography

Creator:: Chirica, Gabriela S.
Abstract:: The challenges prompted by miniaturization of chromatographic systems have led scientists to explore new avenues in the synthesis of stationary phases. Packed capillary columns have found limited application in routine analysis due to a number of technical difficulties, most of which are attributable to the frits. New column designs insure...

Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

Creator:: Rodríguez Pérez, Ismael A.
Abstract:: Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

Luminescent sulfides and solution-deposited oxide thin films

Creator:: Anderson, Jeremy T.
Abstract:: Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

Label-free mass spectrometry-driven methods for elucidating adaptive responses of the hepatic mitochondrial proteome in an alcoholic fatty liver disease model

Creator:: Tzeng, Shin-Cheng
Abstract:: Alcoholic liver disease (ALD) continues to be one of the major public health problems in the United States and worldwide. Complicated by factors including gender, polymorphisms of alcohol-metabolizing enzymes, immunologic factors, exposures to other substances/drugs, hepatic viral infections, nutritional deficiencies, and obesity, ALD is a complex disease that requires a...

Novel ternary graphite intercalation compounds of alkali metal cations and amines

Creator:: Maluangont, Tosapol
Abstract:: Novel ternary graphite intercalation compounds (GICs) of alkali metal cations and a wide variety of amines have been synthesized by one-pot chemical syntheses. Alkali metals studied includes Li, Na and K. The families of amines employed are nalkylamines, branched alkylamines, and different structural isomers of diamines and polyamines. Intragallery structures...

Satellite structure in the gas-phase X-ray photoelectron spectra of planar unsaturated molecules

Creator:: Chambers, Scott Alexander
Abstract:: The satellite structure ("shake-up") present in the X-ray photoelectron spectra of several planar molecules containing double bonds has been investigated in the gas phase. This set consists of three five-membered heterocyclic molecules, ethylene and two of its fluorinated analogs, and benzene with three of its fluorinated analogs. In addition, core...

The retro-ene reaction of 2-vinylcyclohexanols and approaches to the synthesis of botryococcene

Creator:: Rusay, Ronald Joseph
Abstract:: The retro-ene reaction of 2-vinylcyclohexanols occurs readily in the vapor phase at 400-450° producing unsaturated carbonyl compounds in good yields. The starting- materials were prepared in general by the carbenoid addition reaction of ethyl diazoacetate, appropriately substituted cyclohexene, and copper catalyst to produce bicyclic esters which were reduced to the...
