Characterization of CoGe Thin Films and Powders

Creator:: Pfau, Andrew James
Abstract:: Cobalt germanides have been widely studied as semiconductor contact materials, but recent theoretical studies suggest that they may also be excellent catalysts for methane steam reforming with stabilities and activities comparable to noble metal catalysts. In order to study the catalytic activity of cobalt germanides, it is critical to first...

Characterizing spin-orbit torques in β-W/Ta/CoFeB/MgO devices

Creator:: Allen, Shane R.
Abstract:: Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...

Quasicrystal Formation, Structure and Indentation Behaviors in Pure Tantalum

Creator:: Wang, Zhengming
Abstract:: Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...

Mixing and Finger Morphologies in Miscible Non-Newtonian Fluid Displacement

Creator:: Mehr, Nicole
Abstract:: We found unexpected complexities resulting from the miscible displacement of a non-Newtonian fluid for both convergent and divergent flow as observed by displacing a miscible shear-thinning fluid (xanthan gum) in a radial Hele-Shaw cell. Such complex patterns have not been described before for either Newtonian or non- Newtonian fluids. A...

Molecular Dynamics Study of structural Evolution, Tensile Deformation and Nanoindentation of Monatomic Metallic Glasses

Creator:: Chen, Fangzheng
Abstract:: Metallic glasses are attracting tremendous attention because of their fundamental significance and great potential to be used as structural or functional materials in engineering applications. Significant efforts have been devoted to studying their unique properties as well as their disordered nature. Metallic glasses possess much higher strength and elastic strain...

Applications of Magnetic Materials in Soft Robotics

Creator:: Davis, William M.
Abstract:: Magnetic materials can be used in modern soft robotics as a method for external stimulus actuation and motion control. By combining aspects of biology and mechanics, devices are fabricated to create a structure capable of complex movement. Applications that these devices are subject to can be broken down into four...

Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

Creator:: Okhovat, Sebastian
Abstract:: Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

Probabilistic Wind Power Forecasting for Hybrid Systems

Creator:: Irmas, Cameron
Abstract:: Wind power forecasting provides valuable insights for demand response, energy market operation, and plant control optimization. Probabilistic approaches—which capture uncertainty in these complex systems by representing predictions as probability distributions—represent a growing area of research in wind energy science. However, their applications for wind-based hybrid systems, particularly those focused on...

Search for Non-Einsteinian Polarization Modes in the Gravitational-Wave Background using NANOGrav’s 12.5 Year Data Set

Creator:: Laal, Nima
Abstract:: I led a collaborative project involving a search for an evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity using NANOGrav’s 12.5 year data set. The search found no substantial evidence in favor of the existence of such correlations. The...

Development of a Novel Device to Measure the Viscosity of High Temperature Molten Salts

Creator:: Blyther, Joshua D.
Abstract:: This thesis presents a novel design for a rheometer style viscometer by implementing high temperature and inert atmospheric requirements on the device. The goals of this device are to measure the viscosity of high temperature molten salts, which are corrosive and extremely hydroscopic. It also aims to be able to...
