  • 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...

  • Studies toward the synthesis of halichlorine and pinnaic acid

    Creator:
    Korf, Eric A.
    Abstract:
    Three approaches toward the core of halichlorine and pinnaic acid are described. The first approach entails a racemic transannular nitrone-olefin [3+2] cycloaddition from nitrone 238. Construction of the nitrone 238 began with aldehyde 241. Another key feature in this route involved a ring-closing metathesis for the formation of a 14-membered...

    Jana, Somnath
    Abstract:
    Studies toward the total synthesis of (+)-providencin (1), a highly oxygenated cembranoid dipterpene with a unique bicyclo[12.2.0]hexadecane skeleton and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 320 and 332 which contain all of the carbon atoms of 1. In a first generation approach...

  • 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....

  • Stationary electrode voltammetry and chronoamperometry in an alkali metal carbonate-borate melt

    Creator:
    Petcoff, Darrell George
    Abstract:
    The electrochemistry of the lithium-potassium-sodium carbonate-borate melt was explored by voltammetry and chrono-amperometry. In support of this, a controlled-potential polarograph and associated hardware was constructed. Several different types of reference electrodes were tried before choosing a porcelain membrane electrode containing a silver wire immersed in a silver sulfate melt. The...

  • 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...

  • 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,...

    Liyanage, Medagama Liyanage Amila Udayanga
    Abstract:
    Novel synthetic strategies are developed to prepare new intercalation compounds and nanocomposites with several layered hosts (NiPS₃, Na-montmorillonite, MoS₂ and MoO₃). In these products, alkali metals are ionic intercalates and linear polymers, dendrimers or amines act as co-intercalates. In addition to new synthetic approaches, new structures are identified and characterized....

    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...
