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...

Synthesis of furanoeremophilane sesquiterpenoids

Creator:: Shanmugham, Meenakshi Sundaram
Abstract:: Two approaches to the tricyclic core of the furanoeremophilane sesquiterpenoids are described. The first approach entails a projected Diels-Alder/retro Diels-Alder reaction of an acetylenic oxazole 64. Construction of the pivotal aldehyde 67 commenced from ketone 68. The acetyenic moiety was then introduced via a Felkin-Ahn addition of lithiopropyne to aldehyde...

Simple models for the structure and dynamics of polyatomic fluids

Creator:: James, Corinne Patricia
Abstract:: Three areas of liquid state theory are considered. First, Monte Carlo computer simulation of a two-dimensional hard disk fluid with an imbedded ellipse was undertaken to determine how a non-spherical molecule affects intermolecular ordering. The elliptical molecule (with axial ratios of 2, 5 and 10) altered the isotropic distribution of...

Development of automated on-line ion exchange systems for the determination of chemical speciation of trace metals in natural waters

Creator:: Liu, Yan
Abstract:: An automated on-line ion exchange trace enrichment system has been developed to improve the detection limits of flame atomic absorption (AA) spectrophotometry in the determination of trace metals in natural waters. The sample solution is passed through a column of Chelex-100 chelating resin by a carrier buffer stream delivered from...

Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

Creator:: Isaacson, Carl W.
Abstract:: To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

Per- and Polyfluoroalkyl Substances (PFASs): Consumer Products, Protocols, and Percutaneous Absorption

Creator:: Rewerts, Justin N.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds gaining notoriety as contaminants of emerging concern. With the frequent detection of PFAS in the environment, drinking water, and consumer products, awareness and concern from the public regarding PFAS is increasing. The two most notorious PFAS are perfluorooctanoate (PFOA)...
