Enhanced electric fields at pointed metal probes for high resolution near-field imaging
(2007-05)
Two methodologies, aimed at increasing the sensitivity and resolution of near-field scanning optical microscopy (NSOM), were explored. The NSOM motifs employed in this study involve the generation of highly localized ...
Capillary electrophoresis-mass spectrometry methods for advancements in proteomics
(2007-05)
Capillary electrophoresis -- mass spectrometry (CE-MS) is increasingly being used in proteomics research. In particular, the speed of analysis, high mass accuracy and sensitivity of many modern mass spectrometers make this ...
Construction of a surface science system for the study of reactive ballistic deposited thin films
(2007-12)
This thesis discusses the construction and modification of an ultra-high vacuum chamber (UHV) and associated instruments for the study of thin film materials prepared by reactive ballistic deposition. In addition to hardware ...
Synthesis and study of new N-heterocyclic carbene frameworks in the pursuit of durable, conductive organic and organometallic materials
(2007-08-13)
A series of group 10 bis(benzimidazolylidene) complexes featuring chelating N- (o-phenol) moieties was synthesized and characterized. Based on these model systems, a new class of main-chain organometallic polymers comprised ...
Studying the properties of conjugated donor acceptor complexes with naphthaleneimide acceptors and dialkoxybenzene donors linked by a triple bond
(2007-12)
The self-assembly of aromatic electron donor and acceptor units into alternating stacks has been studied extensively by the Iverson research group as well as others. As an extension of previous research in this area, novel ...
Organocatalytic Michael cycloisomerization : studies toward the total synthesis of morphine
(2006-12)
The organocatalytic Michael cycloisomerization has been utilized in both methodological and synthetic chemistry by our research group. This paper investigates the extension of this methodology to other electron deficient ...
Application of dendrimer encapsulated Pd nanoparticles in carbon-carbon coupling reaction (the Stille reaction)
(2006-08)
This thesis examines the chemistry and application of dendrimer-encapsulated Pd nano-partilces in carbon-carbon coupling reactions in homogenous solution. We prepare our dendrimer encapsulated Pd nano-particles and study ...
Array-based split-pool combinatorial screening of potential catalysts
(2006-08)
A new method for screening split-pool combinatorial libraries for catalytic activity is described. Site-selective detection of catalytic activity for solution-based reactions was made possible without co-functionalizing ...
Semi-empirical prediction of penultimate monomer effects on relative rates of copolymerization propagation
(2005-05-21)
The penultimate effect on free-radical copolymerization is investigated by semi-empirical (AM1) calculation. By a proposed model dimeric monomer, different e values are assigned to the radical end according to the penultimate ...
First generation of fluorescent labeled DNA bis-intercalators
(2005-12-24)
Understanding biochemical functions at the most basic level promises greater understanding and control over cellular processes. Synthetic molecules that specifically bind double helical DNA have been pursued as a means of ...
