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...

The role of molecular architecture in the hydration properties of brewers’ spent grain

Creator:: Yang, Jasmin S.
Abstract:: An emerging strategy to reducing food waste is converting food processing byproducts to nutritious and inexpensive food ingredients. A relevant food processing waste stream is brewers’ spent grain (BSG), the primary byproduct of beer production. BSG is a promising candidate as a food ingredient because of its high protein and...

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...

Design and Fabrication of a Polymeric Microfluidic Device for Automated

Creator:: Warner, Kelsie E.
Abstract:: Gene synthesis is an important tool in molecular biology. However, the current bench-top method of gene synthesis is a costly, time-intensive and reagent-consuming process. Lab-on-chip technology has many benefits over current bench top methods. Microchips consume smaller reagent volumes, are reusable and less expensive to make. This thesis explores the...

New Inorganic Pigments from Mineral Structures

Creator:: Schettini Mejia, Carlo A.
Abstract:: The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...
