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...
Understanding how spin waves propagate through ferromagnets is an important component of a wider international effort to create spintronic devices. In this thesis, we develop a propagating spin wave spectroscopy to make a variety of measurements on thin films of Yttrium Iron Garnet (YIG), a material known for having long...
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...
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...
This is a detailed study of Congress's China policy, with a view toward building a theory of congressional policymaking. I argue that committees, bicameralism, and presidential veto have severely constrained Congress's ability to legislate on China policy. I analyze China bills introduced between 1973 and 2006. I report evidence that...
In high power density transmission systems, Ni-Co secondary hardening steels have shown great potential for next-generation gear applications due to their excellent strength, toughness and superior fatigue performance.
Study of residual stress generation and evolution in Ferrium C61 and C67 gear steels revealed that shot peening and laser peening processes...
The combined trends of decreasing application size and increasing requirements for energy efficiency have driven a need for improved understanding and better predictive tools for thin film lubricated systems. Research on such systems is complicated by the involvement of both larger scale phenomena such as fluid flow, material deformation, and...
It has commonly been observed that a person's performance on a self-regulation activity is often impaired when he or she has already performed a prior task that requires substantial self-regulation, a phenomenon termed as the regulatory depletion effect. The prevailing explanation for this effect, as reported in the literature, is...
A spokesman for the American Revolution, John Adams, famously claimed that a third of colonists supported independence, a third supported Britain, and a third remained neutral. Since then historians have struggled to understand the mixed loyalties of the Revolutionary generation.
"The Popular Politics of Loyalism During the American Revolution, 1774-1790,"...
Assets are ubiquitous, required for consumer behaviors and meaningful in American society. Though assets have a central role in society, they have been considered primarily for what they can buy. This continual focus on assets as an instrument for exchange masks the fact that assets also may serve as a...
