Design and Properties of Novel Uranium-Containing Layered and Framework Materials

Shvareva, Tatiana (2006-12-15)

Ten uranyl-containing frameworks and one layered material have been synthesized under hydrothermal conditions. These compounds belong to eight structure types, not previously described. They are constructed from uranyl ...

Development of CaZrO3-Based Hydrogen Sensors with Oxide Reference Electrodes for Molten Aluminum

Krishnan, Vivek (2006-12-15)

Hydrogen is a major cause of gas porosity in aluminum and is frequently removed from the melt prior to casting. The degassing process can be better controlled if the hydrogen content in the melt is known. Thus, gas sensors ...

Electrocatalytic and Antibacterial Applications of Sandwich Type Polyoxometalates

Sankarraj, Anand (2008-12-15)

The primary goal of this dissertation is to study the structure-property relationship of sandwich type polyoxometalates and to employ these versatile molecules in electrocatalytic applications such as oxygen generation and ...

Enhancing Expression of Recombinant Hemoproteins: Progress Toward Understanding Structure/Function and Therapeutic Application

Varnado, Cornelius (2006-08-15)

Nature has developed ways to control the essential need to activate oxygen. Hemoproteins perform this task using iron in a prosthetic group (e.g., iron-protoporphyrin-IX or heme). The environment surrounding the heme iron ...

Hydrothermal Syntheses, Structures, and Properties of New Iodate and Selenite Compounds of Transition Metals, Lanthanides, and Actinides

Ling, Jie (2007-12-15)

Iodate and selenite anions possessing a nonbonding, but stereochemically active lone pairs of electrons, were selected as building blocks to produce new compounds with noncentrosymmetric structures, a prerequisite for ...

Hydrothermal Synthesis and Characterization of Novel Thorium, Uranium, and Neptunium Solids

Sullens, Tyler (2005-08-15)

Hydrothermal synthesis has been utilized to synthesize several compounds involving thorium, uranium, and neptunium. These compounds have one-, two-, and three-dimensional structural typologies. A majority of the compounds ...

Preparation, Characterization, and Applications of Polysaccharide-stabilized Metal Nanoparticles for Remediation of Chlorinated Solvents in Soils and Groundwater
