Theoretical and physical investigations of group 9-14 metal complexes containing the diphenylmethylenethiophosphinate (MTP) ligand : effect of metal proximity on physical properties
(1993)
A trimetallic complex, [Hg2Pt(CH2P(S)Ph2)4]X2 (X = BPh4-, PF6-, 1a , b), was obtained from the reaction of Hg(MTP)2 (MTP = CH2P(S)Ph2-) with one equivalent of Pt[S(CH2CH3)2]2Cl2, in CH2Cl, in the presence of either NaBPh4 ...
Probing the relationship between the acid-induced denaturation of Transthyretin and amyloidosis
(1993)
The pH-induced denaturation of Transthyretin (TTR) was studied in order to understand the biochemical basis of TTR's amyloidogenicity. The structural changes were monitored by UV, circular dichroism, and fluorescence ...
The synthesis and characterization of mixed derivative single phase solid solutions of divalent and trivalent metal ions
(1993)
This dissertation presents the synthesis, characterization and reactivity of layered mixed derivative solid solutions of divalent and trivalent metal phosphonates, namely the phenylphosphonate phosphite mixed derivatives ...
Surface modification of polyolefins using new synthetic techniques
(1992)
A new technique for functionalization of polyolefin surfaces using C-H bond activation catalysts has been developed. The Gif system which was developed by the Barton group as a model of methane monooxygenase has been ...
Surface electrochemical studies of iodine adlattices on Pd(111) and Pd(100) single-crystal electrodes
(1992)
The structure, composition and electrochemical reactivity of iodine adsorbed from aqueous iodide solutions onto Pd(111) and Pd(100) single-crystal electrodes have been investigated. Characterization of the I/Pd system ...
Vibrational spectroscopic studies of adsorbates on bimetallic surfaces
(1992)
In this work, well-defined bimetallic surfaces have been studied using carbon monoxide adsorption in conjunction with infrared reflection absorption spectroscopy (IRAS). These studies have indicated that for CO adsorbed ...
Syntheses, structures and magnetic properties of compounds containing linked, multiply-bonded dimetal units
(1993)
The tetranuclear compounds [{M2(chp)4}(pyz)](BF4)2 (M = Ru, Os) and the dinuclear compounds [M2(chp)4(py)](BF4) (M = Ru, Os) have been synthesized and characterized by X-ray crystallography and by magnetic susceptibility ...
Vibrational potential energy functions and conformations of cyclopentanone and cyclobutanone in their electronic excited states
(1993)
T he jet-cooled fluorescence excitation spectra o f cyclopentanone, cyciobutanone and their isotopom ers have been recorded in the 305-335 nm region, respectively. T he electronic band origin for the tw o undeuterated ...
Electronically conductive polymer composites and microstructures
(1993)
Composites of electronically conductive polymers with insulating host materials are investigated. In this context, the author has attempted to accomplish the following objectives: i) A template synthesis method was developed ...
GDR Gamma-ray emission as a probe of fission dynamics
(1993)
Presented in this dissertation is a study of fission dynamics and shape evolution in rapidly rotating nuclei. This has been accomplished via measurements of [gamma]-rays in coincidence with fission fragment emission. The ...
