Classification of stationary phases in gas chromatography

Creator:: Chong, Elee Elizabeth
Abstract:: Ultraviolet spectroscopy and dispersive solubility parameters correlated to the ratios of retention times have proven valuable in classification of gas chromatography stationary phases by the donor-acceptor properties. Iodine was directly dissolved into stationary phases and the absorption frequency shift of complexes was correlated with the carbon tetrachloride/chloroform retention ratio on...

Decomposition of di-p-toluenesulfonyl-hydrazones

Creator:: Bradway, Diane Elizabeth
Abstract:: Thermal decomposition of several di-p-toluenesulfonylhydrazones was studied. It was found that the carbene decomposition of tetramethyl-1,3-cyclobutanedione, di-p-toluenesulfonylhydrazone gave two products resulting from rearrangement. One was identified as 2,5-dimethyl-1,3,4-hexatriene. A tentative structure for the second was proposed. During the course of the study, a more convenient procedure for thermal decompositions was...

Insights into Cytostatic and Cytotoxic Properties of the Natural Product Mensacarcin

Creator:: Kaweesa, Elizabeth Namagoba
Abstract:: Mensacarcin is a stereogenic complex polyketide with potent anti-tumor activity produced by a soil-dwelling Streptomyces bottropensis. The US National Cancer Institute (NCI) 60 human tumor cell line anticancer drug screen (NCI-60) reveals mensacarcin’s cytostatic properties in almost all tested cell lines and distinct cytotoxic properties specifically in eight melanoma cell...

Fusion enhancement with neutron-rich radioactive beams

Creator:: Zyromski, Kristiana Elizabeth
Abstract:: Fusion reactions with radioactive neutron-rich projectiles have been the subject of much recent theoretical and experimental interest. Predictions of enhancement of the cross section due to the use of a neutron-rich projectile may have implications for synthesis of heavy nuclei. In this work, the fusion-fission excitation functions were measured for...

Designing Functional Materials Based on Pyrochlore Oxides: The Role of Mixed Valence and Complex Stoichiometry

Creator:: Converse, Elizabeth Maria Sobalvarro
Abstract:: Solid state inorganic oxides play an important role in next generation electronics based on their stability, versatility, and enhanced properties over other materials. However, in order to design or tune these materials for a desired functionality it is necessary to fully understand the structure behind the properties exhibited. This dissertation...

A Diels-Alder approach to biaryl synthesis

Creator:: Ashburn, Bradley O.
Abstract:: An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

The determination of titanium, zirconium and hafnium in molybdenum, niobium and tantalum alloys by ion exchange

Creator:: Shakashiro, Mouaffac Hamdy
Abstract:: New alloys containing refractory metals have been developed by the aero-space industry to meet the demand for thermally resistant materials. The chemical analysis of these alloys has been handled successfully by the use of ion exchange. Hydrofluoric acid, either alone or combined with hydrochloric acid, has here-to-fore been used to...
