  • Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

    Creator:
    Killin, Robert K.
    Abstract:
    Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

  • Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

    Creator:
    Primbs, Toby
    Abstract:
    The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

  • High quantum-yield phosphors via quantum splitting and upconversion

    Creator:
    Jeong, Joayoung
    Abstract:
    The Gd3+ ion has been used to induce quantum splitting in luminescent materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+ followed by...

  • 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...

  • Theory of negative thermal expansion

    Creator:
    Tao, Ju Zhou
    Abstract:
    Two framework oxide materials of the MO₃ network type have been synthesized and structurally characterized by synchrotron and X-ray powder diffraction and the Rietveld method in the temperature range 25~500 K. The results show one of them to be a low thermal expansion material. Theoretical studies of negative thermal expansion...

  • Polyion sensors based on induced ion extraction

    Creator:
    Fordyce, Katherine
    Abstract:
    A novel method for detecting the peptidase activity of clinically relevant peptidases was investigated using solid-contact electrochemical polyion sensors under chronopotentiometric control. Complete instrumental control over ion-extraction was accomplished by incorporating a lipophilic electrolyte into the ion-selective membrane; the sensors had no intrinsic ion-exchange capabilities. The sensors were used to...

  • Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

    Creator:
    Chiaia Hernandez, Aurea C.
    Abstract:
    A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...

  • Synthesis and structure of new transition metal containing bismuth oxides

    Creator:
    Xun, Xiumei
    Abstract:
    Exploratory synthesis is the discovery of new compounds with interesting structures and properties. The subject of this thesis is exploratory synthesis of bismuth containing oxides. Bismuth containing oxides have many interesting properties, which are ionic conductivity, ferromagnetism, superconductivity, ferroelectricity, ferroelasticity and catalytic. These properties are closely related to their specific...

  • Galvanostatic control of ion selective electrodes with the solvent polymeric membrane

    Creator:
    Perera, Hasini R.
    Abstract:
    Detection technique that proposed utilizing electrochemically controlled, reversible ion extraction into polymeric membrane in an alternating galvanostatic/ potentiostatic mode was introduced. This method is studied in detail to comprehend the advantages of the novel sensor (pulstrode) compared to the potentiometric ion selective electrode (ISE), studies included possible applications and limitations....
