The measurement of weak adhesive energies has previously been difficult to obtain. To measure these energies, I designed a technique that uses the combined sensitivities of both a quartz crystal resonator and the inflation of an elastomeric polymer membrane. The surfaces of the quartz crystal and/or the membrane are modified...
The current trend of ceramic nanotechnology has motivated an ever-increasing need to achieve exquisite control over size, shape, and spatial confinement for functional oxide architectures, in an equivalent manner demonstrated for semiconductors. However, the unique nature of ceramics has posed major challenges for most traditional nanofabrication technologies, putting the development...
The electronic properties of various transparent conducting oxide (TCO) surfaces are probed electrochemically via self-assembled monolayers (SAMs). A novel graftable probe molecule having a tethered trichlorosilyl group and a redox-active ferrocenyl functionality (Fc(CH2)4SiCl3) is synthesized for this purpose. On as-received ITO, saturation coverage by a close-packed monolayer having of 6.6...
Two new methods have been developed employing silicon-containing molecules in novel organic transformations. The first strategy utilizes Lewis base-activation of triethoxysilylalkynes to deliver mild acetylide nucleophile equivalents. The second approach involves the use of enolate additions to acylsilanes to generate β-silyloxy homoenolate intermediates.
Lewis base-catalyzed activation of triethoxysilylalkynes promotes the...
The present studies aimed at developing a lie detection paradigm immune to countermeasures, while the theoretical issues of top-down influence of task requirement on subliminal semantic priming were investigated. In Experiment 1, subjects were presented supraliminal acquaintance and non-acquaintance names, which were subliminally primed by another acquaintance or non-acquaintance names....
Living organisms grow precisely controlled assemblies of inorganic crystals using organic substrates. This observation has inspired the strategy of using synthetic organic templates for the growth of tailored inorganic thin films. It has been previously shown that monomolecular organic layers floating on supersaturated aqueous subphases (Langmuir monolayers) select the structure...
In this thesis, we study routing and resource allocation problems which have probabilistic objective functions. This class of problems has received limited attention in literature despite its promising applications. A probabilistic objective function is capable of incorporating business targets into the problem modeling and representing the risk attitude of a...
Development of the central nervous system requires the coordinated interplay of intrinsic and extrinsic factors. I examined the actions of an extrinsic factor, TWEAK, and an intrinsic factor, Iroquois1 (Irx1) on neural progenitor cell behavior. Embryonic day 12 (E12) and post-natal day 1 (PN1) neural progenitor cells both express Fn14,...
Multiple Myeloma (MM) is an incurable plasma cell malignancy occurring within the bone marrow. Glucocorticoids (GCs) are widely used in the treatment of MM patients due to potent induction of apoptosis. Though known to occur via the glucocorticoid receptor (GR), the molecular details of GC-induced apoptosis in MM cells remain...
Oxide surface structures play a key role in many technological processes, including catalysis, thin film growth, and layered structures, and a thorough understanding of surface structures and surface structure dynamics is required in order to better engineer materials systems for these processes. This research works towards understanding these fundamental principles...
