Monitoring redox conditions with redox indicators during microbial reductive dechlorination in microcosms and bioaugmented columns

Creator:: Ruiz-Haas, Peter A.
Abstract:: New methods, sensors, and devices based on redox indicators were developed to monitor redox conditions in anoxic and anaerobic laboratory systems and the subsurface environment. The primary application was monitoring redox conditions during the dechlorination of tetrachioroethene (PCE) to ethene (ETH) in packed columns and microcosm bottles containing an enriched...

Micro total analysis system for in-situ and autonomous spectrophotometric monitoring of iron in groundwater

Creator:: Koch, Corey R.
Abstract:: We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...

Uranyl Peroxide Cluster Formation Pathway and the Role of the Alkali Counterion

Creator:: Arteaga, Ana
Abstract:: Uranyl peroxide clusters are the newest family of polyoxometalates, discovered in 2015. Although this family is new, over 70 topologies have been reported. However, we lack the fundamental understanding of assembly mechanisms, particularly the role of the alkali countercations. Here, we use a wide range of solution and solid-state characterization...

Part I: Synthesis and evaluation of synosutine as an inhibitor of serotonin, norepinephrine, and dopamine transporters Part II: Asymmetric approach to the tetracyclic core of neomangicol A

Creator:: Juniku, Rajan B.
Abstract:: Part I: Racemic and asymmetric syntheses of a new substance with prospective antidepressant properties were achieved. In vitro assays with synthetic racemates (±)-25 and (±)-26 suggested that the former is a relatively selective inhibitor of serotonin transporter whereas the latter is a more balanced inhibitor of both serotonin and norepinephrine...

Mechanistic studies on Re(V) mediated C-O bond transformations

Creator:: Zhuravlev, Fedor
Abstract:: In situ, reduction of Cp*ReO₃ by PPh₃ to form (Cp*ReO)₂(μ-O)₂ allows catalytic deoxygenation of epoxides, however, conproportionation between Reⱽ and Reⱽᴵᴵ species to form clusters of ((Cp*Re)₃(μ-O)₆}²⁺(ReO₄⁻)2 and new compound {(Cp*Re)₃(μ²-O)₃(μ³-O⁾³ReO₃}⁺(ReO₄⁻) leads to removal of rhenium from the catalytic cycle and loss of activity, The epoxide deoxygenation mediated by (Cp*ReO)₂(μ-O)₂...

Development of Carbon-based Ion Selective Microsensors as Scanning Electrochemical Microscopy (SECM) Probes

Creator:: Ummadi, Jyothir Ganeshwar Reddy
Abstract:: The general theme of this dissertation is the application of novel carbon based micro sensors with the scanning electrochemical microscopy (SECM). SECM allows positioning of the probe without touching the substrate while mapping the chemical parameters in 3D space above the substrate. The main focus of the dissertation is the...

New Graphite Intercalation Chemistry with Ethers and Amines

Creator:: Zhang, Hanyang
Abstract:: Novel donor-typed ternary graphite intercalation compounds (GICs) are synthesized and characterized containing (1) pyrrolidinium cations with DMSO co-intercalates; (2) alkali metal cations with crown ether co-intercalates; and (3) alkali metal cations with polyethylene glycol co-intercalates. Structural and compositional data are obtained for the stable products. A new ether-amine co-intercalate exchange...
