  2. Metal-organic frameworks as hydrogen storage materials: effects of framework reduction and cation doping

    7p88cg75d?file=thumbnail
    Description: The safe and efficient storage of hydrogen is possibly the chief obstacle to its use as a fuel on a large scale. Metal-organic frameworks (MOFs) are well poised to provide unique solutions to hydrogen storage, and gas storage in general, a result of their crystalline, porous networks that present the...

  3. Synthesis, Properties, and Applications of Colloidal Gold Nanoprisms

    Q237hs128?file=thumbnail
    Description: Au nanoprisms are a new type of inorganic nanoparticle that is particularly interesting because these particles can be made in high yield, are composed of a metal with well known surface chemistry, exhibit strong, architecture and environment-sensitive optical features, and have well-defined crystallographic facets. All of these features make Au...

  6. Insights on the Intracellular Mechanism of Action of the Anticancer and Antiangiogenic Copper Chelator Drug: Ammonium Tetrathiomolybdate (TM)

    6682x408d?file=thumbnail
    Description: The biological antagonism between copper and molybdenum, first observed when cattle developed copper deficiencies after ingesting high levels of plant-born molybdenum, is currently being used in humans to treat two conditions: Wilson's Disease as well as several forms of metastatic cancer. There is surprisingly little known about the interaction of...

  7. Peptoids as Monodisperse, Multivalent Scaffolds for End-Labeled Free-Solution Electrophoresis (ELFSE) and Magnetic Resonance Imaging (MRI)

    Bk128b124?file=thumbnail
    Description: The need for readily synthesized scaffold architectures to build monodisperse, high molar mass mobility modifiers or "drag-tags" in end-labeled free solution electrophoresis (ELFSE) led to the development of a novel class of multivalent molecular tools. Poly-N-substituted glycines (peptoids) were created with evenly spaced amino groups as branching points along the...

  8. Coordination Complexes for the Development of Zn(II)-Activated MR Imaging Probes

    4q77fr47z?file=thumbnail
    Description: My thesis focuses on the design and synthesis of lanthanide coordination complexes as Zn(II)-responsive magnetic resonance imaging (MRI) contrast agents. These agents produce an increase in MR intensity upon binding of Zn(II) through water modulation to Gd(III) chelates. To this end, several Zn(II)-responsive contrast agents have been synthesized and studied...

    M613mx805?file=thumbnail
    Description: Particulate methane monooxygenase (pMMO) is a membrane-bound metalloenzyme that oxidizes methane to methanol in methanotrophic bacteria. The nature of the pMMO active site and the overall metal content are controversial, with spectroscopic and crystallographic data suggesting the presence of a mononuclear copper center, a dinuclear copper center, a trinuclear center,...
