Effect of Water on Thermoelasticity of Majoritic Garnet: Implications for the Seismic Structure at the Top of the Lower Mantle

Description:

High-pressure and high-temperature laboratory experiments on the physical properties of mantle minerals provide a window into the Earth’s interior chemistry and geodynamics. The measurement of material density, compressibility, and elasticity at high P-T conditions provides thermoelastic parameters necessary to model seismic velocities in the Earth’s mantle at regional and global...

Modeling thin film oxide growth.

Description:

Thin film oxidation is investigated using two modeling techniques in the interest of better understanding the roles of space charge and non-equilibrium effects. An electrochemical phase-field model of an oxide-metal interface is formulated in one dimension and studied at equilibrium and during growth. An analogous sharp interface model is developed...

Formwork Pressure of Self-Consolidating Concrete: Influence of Flocculation Mechanisms, Structural Rebuilding, Thixotropy and Rheology

Description:

While self-consolidating concrete (SCC) may no longer be considered a "new concrete", there are still significant challenges to overcome before there is broader acceptance of SCC. One of these challenges concerns the formwork pressure exerted by SCC. A major advantage of SCC is the accelerated casting process due to the...

Nanoscale Investigation of Platinum Nanoparticles on SrTiO3 Grown via Physical Vapor Deposition and Atomic Layer Deposition

Description:

This dissertation examines growth of platinum nanoparticles from vapor deposition on SrTiO3 using a characterization approach that combines imaging techniques and X-ray methods. The primary suite of characterization probes includes atomic force microscopy (AFM), grazing-incidence small-angle X-ray scattering (GISAXS), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray absorption spectroscopy...

Computational Design of Precipitation-Strengthened TiNi-Based Shape Memory Alloys

Description:

Motivated by performance requirements of future medical stent applications, experimental research addresses the design of novel TiNi-based, superelastic shape-memory alloys employing nanoscale precipitation strengthening to minimize accommodation slip for cyclic stability and to increase output stress capability for smaller devices. Using a thermodynamic database describing the B2 and L21 phases...

Self-Assembly of Organic Semiconductors and their Mineralization into Hybrid Nanostructures

Description:

This dissertation demonstrates how self-assembly can direct nanoscale ordering and optimize electronic properties of organic semiconductors, as well as organic-inorganic hybrids. In excitonic solar cells, controlling the ordering and interfaces between electron-transporting (n-type) and hole-transporting (p-type) domains is crucial. In addressing this challenge, hybrid nanostructures were designed by mineralization of...

Microstructure and Creep Properties of Al-Sc Alloys Micro-alloyed with Lanthanides (Yb or Gd) and Transition Metals (Ti or Zr)

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...
