Influence of some dissolved salts, chiefly nitrates, upon the precipitation of lead chloride in qualitative analysis

McWhorter, Zella A. (University of Alabama Libraries, 1915)

In following the various procedure of Qualitative Analysis the purpose of the operator is to separate, as completely as possible, the substances present and to identify each in its proper order. Experience has shown the ...
Inhibition of an E. coli DNA glycosylase, MutM, by non-native metals

An, Mier (University of Alabama Libraries, 2013)

Non-native metals are well recognized carcinogens; however, most exhibit low mutagenicity. One route by which metals could contribute to carcinogenesis is by inhibition of crucial DNA repair processes. The protein targets ...
Investigation of protein dynamics in glycosyltransferases with the GT-B structural fold

Chen, Wen (University of Alabama Libraries, 2019)

Carbohydrate transfer reactions are significant for organisms and are involved in a variety of functions in cells. This complicated system is controlled by enzymes including glycosyltransferases (GTs). GTs catalyze sugar ...
Investigation of protein-protein interactions in the suf pathway for fe-s cluster assembly in escherichia coli

Kim, Dokyong (University of Alabama Libraries, 2018)

Fe-S cluster cofactor biogenesis is critical to the survival of bacterial pathogens and is carried out by multiprotein biosynthetic pathways. In E. coli, the SUF system is one of three distinct pathways for Fe-S cluster ...
Investigation of regulatory and functional diversity in an enzyme superfamily

Kumar, Garima (University of Alabama Libraries, 2015)

Understanding the evolution of functional and regulatory diversity in enzyme superfamilies addresses a fundamental biochemical problem by improving our ability to identify and exploit structure/function relationships. It ...
Ionic liquids and chitinous biomass: materials, synthesis, and applications for uranium sequestration

Griggs, Christopher Scott (University of Alabama Libraries, 2016)

The mining of Uranium (U) ore, processing, and applications in weapons manufacturing and nuclear fuel have resulted in a legacy of contamination that require the creation of innovative methods that provide waste to volume ...
Ionic liquids platform for biomass dissolution leading to advanced biocomposite materials

Maxim, Mirela Liliana (University of Alabama Libraries, 2012)

The focus on biomass as a renewable resource has been triggered by the increasing demand for non-renewable supplies and the distress of imminent depletion of petroleum reserves. The term "biorefinery" has been defined in ...
Iron coordination and protein-protein interactions of the protein frataxin

Gentry-Dye, Leslie (University of Alabama Libraries, 2014)

Frataxin is a mitochondrial iron metallochaperone that transports ferrous iron to proteins that require it for function. This dissertation research explores the iron binding properties of human frataxin and how frataxin ...
Isolation of soft donor complexes of d- and f-block metals using ionic liquids

Kelley, Steven Paul (University of Alabama Libraries, 2015)

Ionic liquids (ILs) are alternatives to conventional molecular liquids or high-melting salts which can be used to gain new insight into long-standing scientific questions. The ability to access a compositionally variable, ...
Low-molecular-weight chromium-binding substance: advanced studies from aves to human

Chen, Yuan (University of Alabama Libraries, 2009)

Chromium has been observed to play a role in maintaining proper carbohydrate and lipid metabolism of mammals. One of the potentially biological active forms of chromium in vitro is low-molecular-weight chromium-binding ...
Magnetic, electrical and magnetotransport properties of Cr O_2 and V O_2-based thin films and heterostructures

Zhang, Xueyu (University of Alabama Libraries, 2013)

In this dissertation, thin films of two promising rutile oxide materials (CrO2 and VO2) are studied. Additionally, magnetic tunnel junctions (MTJs) with these two materials as ferromagnetic (CrO2) ...
Mass spectrometry studies of peptides cationized by trivalent metal ions

Commodore-Botoklo, Juliette Joan (University of Alabama Libraries, 2018)

The field of proteomics is dedicated to understanding how a protein’s structure and function relates to human health and disease. Peptide sequencing by mass spectrometry is important to the proteomics movement. Unfortunately, ...
Mechanism Studies of the Retropinacol Reaction

Payne, Lamar Bishop (University of Alabama Libraries, 1962)

The purpose of this study was to synthesize the p-toluene-sulfates and methanesulfates of cis- and trans-2,2,5,5-tetramethyl-1,3-cyclohexanediol and to determine their behavior toward solvolytic and substitution reactions ...
Mechanistic studies of water oxidation and carbon dioxide reduction using transition metal catalysts with protic ligands

Burks, Dalton Bodine (University of Alabama Libraries, 2019)

The majority of energy produced in the world is derived from fossil fuels which are finite and have deleterious environmental effects. For a sustainable and environmentally-friendly energy future, alternative, renewable ...
Medusa particles: a magnetically triggered drug delivery system consisting of peg-pcl diblock polymer brushes bound to the surface of single crystal magnetite nanoparticles

McCormick, Benjamin Joseph (University of Alabama Libraries, 2016)

Current cancer chemotherapy treatment involves intravenous administration of highly toxic drugs relying on the strategy that some of the chemotherapy agent will reach the site of cancer and effectively kill those cells. ...
Metal oxide thin films by chemical vapor deposition for photocatalytic water splitting

Panikar, Archana Sathyaseelan (University of Alabama Libraries, 2016)

Photoelectrochemical cells (PEC) are devices which convert solar energy into consumable chemical energy by splitting water into oxygen and hydrogen. Photocatalytic activity at a semiconductor oxide surface forms the backbone ...
Nanocrystals and thin films of oxide and chalcogenide spinels for spintronic applications

Wang, Yu-Hsiang (University of Alabama Libraries, 2010)

Spin-based transport in semiconductor systems has been proposed as the foundation of a new class of spintronic devices. For the practical realization of such devices it is important to identify magnetic materials with ...
Nanostructured silver for applications in surface enhanced Raman spectroscopy and photoelectrochemical reactions

Clayton, Daniel Adam (University of Alabama Libraries, 2014)

Initial work focused on characterizing silver and its surface enhanced Raman spectroscopy (SERS) capabilities. Silver nanowires were chosen as an ideal material and scanning confocal microscopy studies were performed to ...
Negative ion mass spectrometry studies of non-traditional deprotonation sites in peptides: gas-phase acidities of amino acid analogs and fragmentation of model phosphopeptides

Plummer, Chelsea Elizabeth (University of Alabama Libraries, 2016)

Studying biomolecule deprotonated anions (amino acids, amino acid amides, phosphorylated amino acids, phosphorylated amino acid amides, and phosphorylated peptides) can further negative ion mode mass spectrometry work in ...
New materials for optical sensing of explosives copolymers containing 2-vinyl-4,6-diamino-1,3,5-triazine and co-crystals of electron rich aromatic molecules and 1,3-dinitrobenzene
