- Description:
- The purpose of this study was to select an alloy with a low driving force for nucleation for a more in-depth study of the nucleation of γ’-precipitates. To do this, three Ni-Cr-Al alloys were chosen close to the solvus line of a Ni-Cr-Al phase diagram, ensuring low supersaturation and therefore...

- Description:
- Second harmonic generation (SHG), a nonlinear optical tool, was used to characterize DNA bound through a chemical linker to the flat surface of a hemispherical lens. Contact angle measurements were used to guarantee that the chemical linker did not hydrolyze under experimental conditions. SHG experiments followed the effects of salt...

- Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...

Transcriptional and Post-Transcriptional Regulation of the Growth Hormone-Releasing Hormone Receptor
- Description:
- In mammalian development, cell specification and organogenesis are achieved by the regulated expression and repression of specific subsets of genes. The anterior pituitary gland, comprised of five cell types that arise from a common precursor, is an excellent model system for understanding these developmental processes. Examination of factors regulating transcription...

- Description:
- Every music theorist has their own personal reasons for engaging in the craft of theorizing about music. Many discover that there is something special about a theoretic disposition which differs from other sorts of interactions with music. It is often this special something that draws musicians into the discipline: specifically,...

- Description:
- Leakage currents limit the operation of high performance type II InAs/GaSb superlattice photodiode technology. Surface leakage current becomes a dominant, limiting factor to the ideal performance of a photodiode, especially at the scale of a focal plane array pixel (< 25 µm), and must be addressed. A reduction of the...

- Description:
- An efficient unified incremental high-level and physical-level synthesis algorithm was presented in Chapter 2, which enable the tight integration between high-level and physical-level design. Chapter 3 presented a temperature-aware high-level synthesis algorithm built upon the framework of Chapter 2. Temperature variations and hot spots account for reliability issue and require...

- Description:
- The contents of this dissertation are divided into two sections: (1) the preparation and characterization of quaternary rare-earth chalcogenides and oxychalcogenides and (2) the localized surface plasmon resonance (LSPR) spectroscopy of metallic nanoparticles fabricated by nanosphere lithography (NSL). Single crystals of CsTmCoS3, CsYbCoS3, CsHoCoSe3, CsYbCoSe3, and CsYbZnSe3 have been prepared...

- Description:
- This dissertation describes the use of alkanethiols and polymers for the development of lithographic affinity and resist array templates that can be utilized for directing the assembly of biological molecules, for building up multilayered polyelectrolyte thin films, and for fabricating metal solid-state nanostructures. The first two chapters of the work...

- Description:
- In this thesis we discuss the issue of solving stochastic optimization problems using sampling methods. Numerical results have shown that using variance reduction techniques from statistics can result in significant improvements over Monte Carlo sampling in terms of the number of samples needed for convergence of the optimal objective value...

- Description:
- This thesis examines the effects of micro-alloying additions to Al-Sc alloys on the microstructure, coarsening resistance and creep properties. The overarching goal of this research is to develop castable, creep-resistant aluminum alloys which can be used at temperatures in excess of 300?C. Successful high-temperature application of aluminum based alloys offers...

- Description:
- This dissertation argues that theatre was a vital element of postcolonial culture in Ireland in the years 1919-1932, the period in which the Irish nation emerged from revolutionary war to become a stable postcolonial state. Although critics have bemoaned the rising dominance of conservative, anti-modernist playwriting and production in Ireland's...
