  • 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...

  • A study of simultaneous diffusion of Ca²⁺ and Sr²⁺ in alkali chlorides

    Creator:
    Machida, Hisashi
    Abstract:
    The simultaneous diffusion of Ca 2+ and Sr 2+ ions in purified single crystals of KC1 and NaC1 was studied over the temperature ranges from 451°C to 669°C in KC1 and from 448°C to 683°C in NaCl. A radioactive tracer technique was used in two types of measurements: diffusion from...

  • CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

    Creator:
    Loughran, Ryan P.
    Abstract:
    We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

  • 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....

  • 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...

  • The kinetic and radiolytic aspects of control of the redox speciation of neptunium in solutions of nitric acid

    Creator:
    Precek, Martin
    Abstract:
    Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...

  • New Treatments for HIV and Cancer: Uncovering Bioactive Compounds from Small Molecule Sources

    Creator:
    Overacker, Ross D.
    Abstract:
    Small molecule drugs have been instrumental in our fight against diseases, beginning when some of the earliest ancient cultures used plant remedies to treat illnesses. More recently, the skill of isolating and characterizing the active ingredients within bioactive plants and microbial extracts has led to the isolation and design of...

    Abstract:
    The central purpose of this dissertation was to explore and expand the use of an uniform electric field for orientation and for subsequent spectroscopic investigation of asymmetric polar molecules in the gas phase. The systems of study were nitrobenzene (NB) and the nitrotoluene (NT) isomers. We were able to quantitatively...

  • Structure-property relationships of oxides with hexagonal AMO₃ and brownmillerite related structures

    Creator:
    Jiang, Peng
    Abstract:
    Transition metal oxides exhibit potential in various application fields due to the special d-electrons. Solid state chemistry focuses on discovering the structure-property relationships. The work in this thesis mainly discusses compounds with hexagonal or brownmillerite-type structure and their practical properties. Hexagonal YIn[subscript 1-x]Fe[subscript x]O₃ (x = 0-0.3, 0.7-1.0) phases have...
