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 ...
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 ...
Hydride thiolate derivatives of low valent iron complexes
(1993)
The highly electron-rich, bis(phosphite) iron hydride complex [Et4N][HFe(CO)2(P(OPh)3)2] has provided synthetic entry to the simple, mono-functional iron thiolates (ArS)Fe(CO)2(P(OPh)3)2- (Ar = Ph, Tol). Both the metal ...
Studies of stereoselective reactions between 2-(trimethylsiloxy)- furan and imines
(1993)
A new, general method for the preparation of 5-aminoalkyl-furan-2(5H)-ones has been developed, and the details of the reaction have been studied. 5-Aminoalkylfuran-2(5H)-ones, which contain two chiral centers, were synthesized ...
Spectroscopic studies of refractory and dielectric thin films
(1993)
This work demonstrated the application of the techniques and methodology of surface science to investigate the mechanisms of thin film deposition processes on solid surfaces. The synthesis of boron nitride (BN) thin films ...
