  • Enzymatic studies of the prenatal chick, with special reference to the multibple forms of liver soluble NADP-linked isocitric dehydrogenase

    Creator:
    Cheung, Geoffrey Peter
    Abstract:
    Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the soluble and particulate fractions of heart, brain and liver at several ages throughout the development of the chick embryo. Compared to isocitric dehydrogenase, levels of glucosesphosphate- , and 6-phosphogluconate- dehydrogenase are generally low. This suggests...

  • Ion-pair high pressure liquid chromatography techniques for the determination of quaternary ammonium compounds

    Creator:
    Starbuck, Brian J.
    Abstract:
    Quaternary Ammonium Compounds, Qams, are an important class of chemicals which present interesting challenges to analysts. This thesis reports results of investigations on uses of ion-pairing techniques for separations and detection of Qams. Special apparatus for post-column solvent extraction of liquid chromatographic eluates was developed as part of this work....

  • Rapid Microwave Synthesis of Indium Filled Skutterudites: An energy efficient route to high performance thermoelectric materials

    Creator:
    Biswas, Krishnendu, Muir, Sean, and Subramanian, Mas A.
    Abstract:
    Filled skutterudites are promising thermoelectric materials due to reduced thermal conductivity upon inserting a guest atom or 'rattler' into the CoSb₃ structure. By using an indium rattler dimensionless Figure of Merit (ZT) values > 1 at 650 K have been reported. The conventional synthesis of these compounds typically takes several...

  • Magnetodielectric Effects from Spin Fluctuations in Isostructural Ferromagnetic and Antiferromagnetic Systems

    Creator:
    Lawes, G., Ramirez, A. P., Varma, C. M., and Subramanian, M. A.
    Abstract:
    We report on the effects of spin fluctuations, magnetic ordering, and external magnetic field on the dielectric constant of the ferromagnet SeCuO₃, and the antiferromagnet TeCuO₃. A model based on the coupling between uniform polarization and the q-dependent spin-spin correlation function is presented to explain the different behaviors for these...

  • Electrochemical studies of liquid chlorocuprates(I)

    Creator:
    Silkey, James R.
    Abstract:
    This research emphasized fundamental physical and electrochemical studies of systems based on the room temperature fused salt, triethyl-ammonium dichlorocuprate(I). Such systems, which must be maintained under a protective atmosphere, were also used in some preliminary battery studies. Spectra of dark green solutions of copper (II) chloride in triethylammonium dichlorocuprate(I) obey...

  • Electrode double layer measurements and voltammetry of some organosulfur compounds in sulfolane

    Creator:
    Starkovich, John A.
    Abstract:
    A new pulse method for measuring differential double layer capacitances has been developed in this work. The technique is based on the determination of the cell time constant which, for an ideally polarized test electrode-solution interface, is composed of the double layer capacitance and solution resistance. By applying small step...

  • 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...

  • Intercalation, exfoliation, and nanocomposites of layered inorganic compounds

    Creator:
    Sukpirom, Nipaka
    Abstract:
    The melt intercalation of poly(ethylene oxide) (PEO) between layers of MoO₃ and MPS3 (M=Mn,Cd) is obtained by heating the ground mixture and LiₓMoO₃, KₓMn₁-ₓ/₂PS₃, or KCd₁-ₓ/₂PS₃. The products are characterized by powder X-ray diffraction (XRD). Below the melting temperature of PEO (66 °C), intercalation rates and yields are low. By...

    Lane, Thomas Alfred
    Abstract:
    This research was on the irreversible oxidation of trimethylamine by copper(II) chloride, which takes place at temperatures of about 75° and higher. The coordination of trimethylamine by copper(II) chloride, which is a preliminary reaction to the oxidation, was studied at 0°. The coordination of trimethylamine by the potential reduction product,...

    Abstract:
    The electrochemistry of cadmium at a Reticulated Vitreous Carbon (RVC) electrode has been studied to determine the suitability of RVC as a working electrode for the electrochemical preconcentration of cadmium in the corrosive environment of zirconium dissolved in hydrofluoric acid. The electrochemistry in this investigation deals with deposition of solid...
