Ion pairing of nucleotides with surfactants for enhanced sensitivity in liquid matrix assisted secondary ion mass spectrometry

Creator:: Pavlovich, James Gilbert
Abstract:: In particle induced desorption-ionization mass spectrometry the strength of an analyte's signal under a given set of bombardment conditions is usually considered to be representative of the analytes relative surface activity. This rationale is generally used to explain differences in the technique's sensitivity between and within various classes of compound....

Gas-phase fragmentation chemistry of protonated peptide ions

Creator:: Bythell, Benjamin James
Abstract:: The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...

Luminescent sulfides and solution-deposited oxide thin films

Creator:: Anderson, Jeremy T.
Abstract:: Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

Proteomic approach to the analysis of DNA-binding proteins using mass spectrometry

Creator:: Stapels, Martha Degen
Abstract:: In proteomic studies, separate experimental protocols have been necessary to identify proteins, determine their function, and predict their three-dimensional structure. In this study, a function-based separation of proteins was conceived to fractionate proteins prior to enzymatic digestion. In the initial demonstration of this technique, a DNA substrate was used to...

Mass spectrometric analysis of UV-crosslinked protein-nucleic acid complexes

Creator:: Doneanu, Catalin E.
Abstract:: The DNA-binding domains of E. coli uracil-DNA glycosylase (Ung) and human replication protein A (hRPA) were studied using a general protocol developed in our laboratory for probing protein-DNA interactions. The procedure involves purification and mass spectrometric analysis of the nucleopeptide-products of a tryptically digested UV-crosslinked protein-nucleic acid complex. In the...

Precursor Chemistry and Film Structure and Properties via Solution Deposition

Creator:: Huang, Yu
Abstract:: Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...

Wide band gap semiconductors and insulators : synthesis, processing and characterization

Creator:: Hersh, Peter A.
Abstract:: The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

On the Properties and Characteristics of Solution Processed Hafnium Based Thin-Films from Aqueous Precursors

Creator:: Decker, Shawn R.
Abstract:: Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...
