Synthesis of α-Ketoester- and α-Hydroxyester-Substituted Isoindazoles via the Thermodynamic Coarctate Cyclization of Ester-Terminated Azo-Ene-Yne Systems

Creator:: McClintock, Sean P., Forster, Nathan, Herges, Rainer, and Haley, Michael M.
Abstract:: The synthesis of isoindazoles bearing α-ketoester and α-hydroxyester groups via the coarctate cyclization of ester terminated azo-ene-yne precursors is described. Whereas previous studies on isoindazole formation have shown the reaction to proceed through a kinetic coarctate pathway, functionalization of the terminal acetylene with a methyl ester sufficiently stabilizes the carbene...

Effect of oxygen concentration on the structural and magnetic properties of LaRh₁/₂Mn₁/₂O₃ thin films

Creator:: Sheets, W. C., Smith, A. E., Subramanian, M. A., and Prellier, W.
Abstract:: Epitaxial LaRh₁/₂Mn₁/₂O₃ thin films have been grown on (001)-oriented LaAlO₃ and SrTiO₃ substrates using pulsed laser deposition. The optimized thin film samples are semiconducting and ferromagnetic with a Curie temperature close to 100 K, a coercive field of 1200 Oe, and a saturation magnetization of 1.7μB per formula unit. The...

Influence of Asian and Western United States Agricultural Areas and Fires on the Atmospheric Transport of Pesticides in the Western United States

Creator:: Primbs, Toby, Wilson, Glenn, Schmedding, David, Higginbotham, Carol, and Simonich, Staci Massey
Abstract:: Historic and current use pesticides (HUPs and CUPs), with respect to use in the United States and Canada, were identified in trans-Pacific and regional air masses at Mt. Bachelor Observatory (MBO), a remote high elevation mountain in Oregon’s Cascade Range located in the United States, during the sampling period of...

Dielectric and polarization experiments in high loss dielectrics: A word of caution

Creator:: Maglione, M. and Subramanian, M. A.
Abstract:: The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state. In this report, we call for caution when samples are simultaneously displaying an insulating behavior and a...

Influence of Asian and Western U.S. Urban Areas and Fires on the Atmospheric Transport of PAHs, PCBs, and FTOHs in the Western U.S.

Creator:: Primbs, Toby, Piekarz, Arkadiusz, Wilson, Glenn, Schmedding, David, Higginbotham, Carol, Field, Jennifer, and Simonich, Staci
Abstract:: Atmospheric measurements of semivolatile organic compounds (SOCs) were made at Mt. Bachelor Observatory (MBO), located in Oregon’s Cascade Range, to understand the trans-Pacific and regional transport of SOCs from urban areas. High volume air sampling (~644 m³ for 24 hour periods) of both the gas and particulate phases was conducted...

Development of fragmentation techniques in mass spectrometry for biological applications

Creator:: Ji, Hong
Abstract:: In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis. Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...

Nonmuscle myosins II-B and Va are components of detergentresistant membrane skeletons derived from mouse forebrain

Creator:: Ishmael, Jane E., Safic, Masa, Amparan, David, Vogel, Walter K., Pham, Tuyen, Marley, Kevin, Filtz, Theresa M., and Maier, Claudia S.
Abstract:: Myosins are actin-based molecular motors that may have specialized trafficking and contractile functions in cytoskeletal compartments that lack microtubules. The postsynaptic excitatory synapse is one such specialization, yet little is known about the spatial organization of myosin motor proteins in the mature brain. We used a proteomics approach to determine...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

Quantifying in situ β-glucosidase and phosphatase activity in groundwater

Creator:: Radakovich, Karen M
Abstract:: Enzymes play an important role in the environment, they breakdown natural-occurring and anthropogenic molecules so that they can be transported into cells and utilized. Enzyme assays are routinely used in soil science and oceanography to measure the activities of specific processes and to serve as general indicators of microbial activity....

Electronic spectroscopy of biological relevant species and their complexes with solvent molecules

Creator:: He, Yonggang
Abstract:: In this dissertation, I present electronic spectroscopy of a few biologically relevant species and their complexes with solvent molecules in the gas phase using a variety of techniques, including resonantly enhanced multiphoton ionization (REMPI), laser induced fluorescence (LIF), and zero kinetic energy (ZEKE) photoelectron spectroscopy. My work on several methylated...
