An investigation of cyanopyrazole ligands and cyanopyrazole scorpionate ligands in the creation of novel transition metal complexes
Kromer, John R. (Wichita State University, 2022-12)Pyrazole ligands are popular ligands in inorganic and bioinorganic chemistry due to isoelectronic structural isomers of imidazole. Pyrazole ligands can combine with metals to make mononuclear structures, polynuclear ... -
Applications of diffuse reflectance near-infrared spectroscopy and cure kinetics study by differential scanning calorimetry to selected thermosetting polymer-based systems of interest in the aviation industry
Gibson, Irish Alcalen (Wichita State University, 2012-05)Diffuse Reflectance Near-Infrared (near-IR) Spectroscopy combined with Partial Least Squares (PLS) regression was used to determine the moisture content and degree of cure in unfilled epoxy resins, carbon-reinforced epoxy ... -
Cyano-substituted polypyrazolylborate metal complexes
Zhao, Ningfeng (2005-12)Polypyrazolylborates have become one of the most popular ligands used in inorganic and organometallic chemistry. Because of the electron-withdrawing and potential coordination property of the cyano group, as well as the ... -
Cyanoscorpionates: New structural motifs for transition metal complexes and coinage metal polymers
Bullinger, John C. (Wichita State University, 2009-05)New complexes have been synthesized of scorpionate ligands with cyano substituents in the 4-positions of the pyrazoles and tert-butyl substituents in the 3-positions of the pyrazoles. Reaction of Co²⁺,Mn²⁺, and Ni(cyclam)²⁺ ... -
Enhancing the performance of an epoxy resin using oligomeric amide additives
De los Reyes, Janet (Wichita State University, 2012-05)An antiplasticizer is any chemical that when added, reduces the free volume of a polymer thereby restricting the polymeric chain motions. This type of additive usually increases the modulus and strength but can compromise ... -
Investigations of cyano-substituted polypyrazolylborate ligands as possible motifs for transition metal complexes and coordination polymers
Kadel, Lava R. (Wichita State University, 2016-05)Polypyrazolylborates, also called scorpionates, have been one of the most popular ligands in inorganic and organometallic chemistry since their discovery. In our research lab, we have been working with a class of ... -
Model complexes for nickel containing enzymes: Carbon monoxide dehydrogenase/ acetyl coenzyme a synthase and nickel superoxide dismutase
Zimmerman, Joshua R. (Wichita State University, 2009-12)Carbon Monoxide Dehydrogenase / Acetyl CoA Synthase (CODH/ACS) is a bifunctional enzyme that catalyzes the reduction of CO₂ to CO and the assembly of Acetyl CoA. The A-cluster active site, which catalyzes the Acetyl CoA ... -
Modeling the active sites of metalloenzymes with thiolate coordination
Moore, Curtis E. (Wichita State University, 2007-12)Nitrile Hydratase (NHase) is a bacterial enzyme which catalyzes the hydrolysis of organic nitriles to their corresponding amides. The active site of NHase contains Fe (III) or Co(III) ions in an unusual coordination sphere ... -
Nickel amine/imine and amine/amide bisthiolate complexes as models for the active site of nickel superoxide dismutase
Senaratne, Nilmini K. (Wichita State University, 2017-07)Nickel Superoxide Dismutase (NiSOD) catalyzes disproportionation of cytotoxic superoxide radical to H2O2 and molecular O2. The mononuclear nickel center in the active site undergoes alternate oxidation and reduction ... -
Synthesis and characterization of nickel imine/amine complexes; a possible model for nickel superoxide dismutase
Mwania, Tom M. (Wichita State University, 2012-05)Superoxide dismutases are ubiquitous enzymes that efficiently catalyze the disproportionation of superoxide radical anions to protect biological molecules from oxidative damage. Several SODs have been identified having ...
