Spectral and Electrochemical Study of the Response of Mechanism of Ionphore-Based Polymeric Membranes
(2008-09-09)
Ion-Selective electrodes based on solvent polymeric membranes, typically plasticized poly-(vinyl chloride), are routinely used and fundamental studies on ion transfer mechanisms that dictate their practicality continue. ...
Exploring Potential Energy Surfaces and Reaction Mechanisms of Inorganic Molecules by Computational Methods
(2008-09-09)
Various computational methods have been applied in order to explore potential energy surfaces (PES) and reaction mechanisms. Theoretical background and computational methods are introduced in chapter 1. Chapters 2-5 ...
Characterization of Two-component Organothiol Mixed Monolayers on Gold and Quantification of Nonspecific Adsorption on Mixed Sam Biosensor Platforms Using Electrochemical Enzyme Immunoassay
(2008-09-09)
Self-assembled monolayer (SAM) technology provides a simple and useful way to functionalize biosensors. The formation and characterization of SAM monolayers are briefly reviewed in Chapter One. Several selected examples ...
Mechanism of the Outer-sphere Oxidation of Aqueous L-cysteine and of Iodide in Acetonitrile by a Series of Iron(III) Complexes
(2008-09-09)
Trace copper catalysis was observed in the oxidation of L-cysteine by [Fe(bpy)2(CN)2]+ and [Fe(bpy)(CN)4]- in anaerobic aqueous solution. The copper catalysis was effectively inhibited with the addition of dipicolinate ...
Hydrothermal Synthesis and Characterization of Novel Thorium, Uranium, and Neptunium Solids
(2008-09-09)
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 ...
Micro-/Nanofabrication in Analytical Chemistry and Temperature Dependent Studies of Underpotential Deposition of Mercury(II) on Au(III)
(2008-09-09)
This dissertation studies three routes to fabricate micro-/nano-sized structures for the purpose of analytical chemistry and the underpotential deposition (UPD) of mercury(II) onto Au(111) electrodes.
In Chapter 2, we ...
Self-Assembled Monolayers as Platform for Biosensors
(2008-09-09)
In chapter one, self-assembled monolayers (SAMs), the platform for biosensors,
were discussed in detail regarding surface pKa, stability, and chemical reactions. Mixed
self-assembled monolayers, especially when incorporated ...
Electrochemical/Electrospray-Mass Spectrometric Studies of the Oxidation of Iodide and Cyanide at Gold and Platinum Electrodes as well as Gas Phase Multiply-Charged Fullerene C60 Anions.
(2008-09-09)
In this dissertation, we introduce a new spherical thin-layer flow cell to interface
electrochemistry with electrospray mass spectrometry. The successful applications of
the electrochemistry with electrospray mass ...
An Approach to Bis(amino Acid)s Utilizing Dimethyl 2,4-bis(diazo)-3-oxoglutarate and Studies of Tris(2,6-dihydroxyphenyl)e, E = B, P.
(2008-09-09)
When treated with a diazo transfer agent, dimethyl 3-oxoglutarate afforded a high yield of the bis(diazo) compound dimethyl 2,4-bis(diazo)-3-oxoglutarate, 33. The bis(diazo) compound, catalyzed by Rh2(OAc)4, reacted with ...
Roles of Two Interhelical Insertions in Catalase-peroxidase Catalysis: Tracing the Impact of Peripheral Protein Structures on Heme Enzyme Function
(2008-09-09)
Monofunctional peroxidases and bifunctional catalase-peroxidases share almost superimposable active sites, yet peroxidases lack appreciable catalase activity. Moreover, catalase-peroxidases catalyze both catalase and ...
