N-HETEROAROMATIC ACID ADLAYER STRUCTURES UNDER HYDROGEN BONDING INFLUENCE:
(2007-02-20)
In this dissertation, I investigate the adsorption and growth of thin films of N-heteroaromatic acids and related molecules on Ag(111) surface. The N-heteroaromatic acids have ring-nitrogen and carboxylic groups. Hence, ...
Synthesis and Reactivity of Monohydrocarbyl Palladium(IV) Complexes Using Hydrogen Peroxide as Oxidant in Protic Solvents
(2011)
Mild, and selective transition metal catalyzed processes for the functionalization of C-H bonds utilizing environmentally benign and inexpensive dioxygen and/ or HOOH oxidants are extremely attractive, as they render these ...
A Thermodynamic Investigation into the Allosteric Activation Mechanism of the Biotin Repressor
(2004-11-05)
The biotin regulatory system of Escherichia coli serves as a model for investigating the regulatory mechanism of a non-classical allosteric transcription factor. The central protein, BirA, functions as both an essential ...
Mechanistic investigations of stoichiometric and catalytic Pt-mediated oxidative functionalization at a proximal boron center
(2013)
The focus of the work detailed in this dissertation is the investigation of mechanism and catalytic applications of Pt complexes supported by novel anionic di(2-pyridyl)borate ligands.
It was found that oxidation of ...
Rhodium(II)-Stabilized Vinylcarbenes: Synthetic Applications in Ylide, Cyclopropanation, and C-H Insertion Reactions
(2006-12-07)
A previously unknown cascade reaction in which two units of a rhodium(II)-stabilized vinylcarbene obtained from methyl trans-styryldiazoacetate react with benzylideneaniline is described; the products of the cascade reaction ...
DEGENERATIVE TRANSFER LIVING ZIEGLER-NATTA POLYMERIZATION OF α-OLEFINS
(2005-12-04)
A degenerative transfer (DT) living Ziegler-Natta polymerization system based on the cyclopentadienyl amidinate zirconium complex, (h5-C5Me5)ZrMe2[N(t-Bu)C(Me)N(Et)] (19), has been studied in detail. Compound 19 is an ...
Dynamics and Chemical Shielding in a Small Protein from NMR Spin Relaxation Experiments
(2006-08-04)
NMR spin relaxation spectroscopy is a proven method for characterization of the time-scales and amplitudes of intramolecular motions in proteins. In a typical NMR relaxation experiment, the significant contributions to ...
Study of Wet-Chemically-Prepared Hydrogen-Terminated Silicon (111) Surfaces and a Novel Implementation of a High-Resolution Interferometer
(2004-04-30)
This thesis summarizes my graduate study under the National Institute of Standards and Technology (NIST) Atom-Based Dimensional Metrology Project, in which we are developing methods for measuring sub-micrometer dimensions ...
Synthesis and Characterization of oligosaccharides tethered to gold films and gold nanoparticles
(2004-12-07)
The goal of this research was to stereoselectively synthesize α- and β- linked glucopyranosylamide derivatives utilizing the modified Staudinger methodology and to tether these derivatives to gold films ...
Application of Silicon-Based Cross-Coupling Technology to Aryl Triflates
(2004-05-06)
The goal of this research was to explore the use of aryl silatranes as a replacement for aryl siloxanes in the palladium-catalyzed cross-coupling reaction with aryl triflates. Phenylsilatrane underwent fluoride-induced ...
