Hu, Huaiyuan (University of Alabama Libraries, 2016)

Part A A synthesis is reported for 9,10-dimethyl-2,3,6,7-anthracenetetra(thioacetate), an anthracenetetrathiol derivative that may find use in molecular electronics and conducting metal-organic frameworks (MOFs). The easily ...
Pattern-based recognition in supramolecular sensing ensemble

Mallet, Alie Marie (University of Alabama Libraries, 2015)

A great deal of attention in studying polyelectrolytes has arisen due to their wide industrial use. These polymers have not received as much attention within the supramolecular chemistry field; the work presented here aims ...
Photo-driven processes toward nanoparticle synthesis: controlled formation via dendritic scaffolds

Williamson, Jonathan Wayne (University of Alabama Libraries, 2012)

Poly(methylamido amine) (PMAAM), poly(methylamide) (PMA), and poly(methylamido methyl amine) (PMAMAM) are spectroscopically analogous to poly(amido amine) (PAMAM) dendrimers, and were used to monitor and influence photo-driven ...
Plasmonic nanoparticles for applications in light scattering spectroelectrochemistry and photoelectrochemical water splitting

Ma, Yanxiao (University of Alabama Libraries, 2019)

Plasmonic gold nanoparticles (NPs) have interesting properties in both surface plasmon resonance and electrocatalytic reactions. However, the mechanism of local redox events at electrocatalytic Au NPs remains uncertain. ...
Polymer-mediated metal and metal oxide nanoparticles: synthesis, characterization and controlled assembly

Bai, Litao (University of Alabama Libraries, 2009)

Functionalized nanoparticles and their assembly have been the subject of intense recent research activity. The stability and assembly of functionalized nanoparticles are still challenges for practical applications. Polymers ...
Potential health benefits of chromium supplementation

White, Pandora Eula (University of Alabama Libraries, 2019)

Trivalent chromium, (Cr(III)), has been used for over 50 years as a “micronutrient”. However, chromium has been shown not to be an essential element. The four studies conducted for this dissertation research attempt to ...
Preparation and novel applications of trihalomethyl carbinols

Li, Zhexi (University of Alabama Libraries, 2015)

Trihalomethyl carbinols have been widely used in organic chemistry and pharmaceutical chemistry as useful intermediates in the preparation of a wide variety of functional groups. Since the discovery of the Jocic reaction ...
Preparation of perfluorinated ionomers for fuel cell applications

Sayler, Todd Stephen (University of Alabama Libraries, 2012)

One of the major issues with the current membrane technology for polymer electrolyte membrane fuel cells is the low conductivity seen at low relative humidity. This dissertation discloses the preparation of perfluorinated ...
The Preparation of Treated and Artificial Resins and Their Use in the Varnish Industry

Marsh, Alfred (University of Alabama Libraries, 1929)

The purpose of this investigation is, therefore, a search for fossil resin substitutes. Natural resins, at present, are often treated to convert them to products that resemble the fossil resins to some extent. Artificial ...
Probing the binding properties of polyelectrolytes as supramolecular hosts

Jolly, Ashley M. (University of Alabama Libraries, 2015)

The use of polyelectrolytes in the field of supramolecular chemistry has flourished in recent years. Specifically, commercially available PAMAM dendrimers have attracted attention due to their large globular structures and ...
Progress toward the synthesis of a Xenia diterpenoid common intermediate and the preparation of inotilone derivatives

Carr, Jeremy Mathew (University of Alabama Libraries, 2009)

Xenia diterpenoid natural products (or xenicanes), isolated from the crude organic extracts of coelentrates, have been shown to possess cytotoxic, antiangiogentic, antimicrobial and anti-inflammatory effects against a ...
Proof of Structure of Some Controversial Sulfonyl Chlorides

McKeown, George Baker (University of Alabama Libraries, 1960)

A comprehensive investigation of reaction mechanisms of sulfonyl compounds was initiated in this Laboratory in 1949. At that time an insight into these reaction mechanisms was sought by determining the steric requirements ...
Reaction of 1-Ethoxyvinyl Acetate with Aliphatic Diazo Compounds

Franklin, James C. (University of Alabama, 1962)

The purpose of the experiments described in this thesis was to prepare certain cyclopropane derivatives by the reaction of 1-ethoxyvinyl acetate with various diazo compounds, and to investigate the behavior of the resulting ...
Redox auxiliary mediated catalysis of organic thermal reactions. Stilbene isomerization and Aza-claisen rearrangement

Nwankwoala, Chinenyeze I. (University of Alabama Libraries, 2018)

This work focuses on the development of new general methods of reducing the activation barriers of organic thermal reactions using a diarylamino redox auxiliary (RA) group. Electron removal from the RA weakens bonds and/or ...
Reliable predictions of the properties of actinide complexes

Jackson, Virgil Edward (University of Alabama Libraries, 2013)

A study of reactions of laser-ablated thorium atoms and O2 using matrix isolation infrared spectroscopy has been conducted using electronic structure calculations to interpret the infrared spectra of three new thorium oxide ...
Solution structure determination for the CYS74 to ALA74 mutant of the catalytic domain of Zoocin A

Xing, Minli (University of Alabama Libraries, 2016)

Zoocin A is a Zn-metallopeptidase secreted by Streptococcus zooepidemicus strain 4881. It has strong inhibitory activity against Streptococcus mutans and thus can serve as a potential treatment for dental caries. The ...
Solution structure of the target recognition domain of zoocin A, an antibacterial enzyme, and the metal binding site of zoocin A

Chen, Yinghua (University of Alabama Libraries, 2009)

A high-resolution structure has been obtained by three-dimensional NMR spectroscopy for the recombinant target recognition domain (rTRD) of zoocin A. The rTRD is a 128-residue protein responsible for targeting the cell ...
Some Novel Reactions of Vinyl Ketene Acetal with a,B-Unsaturated Enone Systems

Chen, Gwo-Ying (University of Alabama Libraries, 1988)

This thesis reports on the addition of vinyl ketene acetals to a, B - unsaturated enone systems, analysis of the reactions products, and the attempted cyclization of the 1,4-adducts to fused-ring systems.
Spectroscopic, structural, and electrical characterization of thin films vapor-deposited from the spin-crossover complex Fe(phen)_2 (NCS)_2

Ellingsworth, Edward (University of Alabama Libraries, 2015)

Thin films (~100 nm) have been prepared of the prototypical spin-crossover complex Fe(phen)2(NCS)2 (phen = 1,10-phenanthroline). Initial attempts to prepare these films by direct vapor deposition yielded films of a different ...
