Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:: Davidson, Peter C.
Abstract:: Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...

Biologically active cyclic depsipeptides from marine cyanobacteria

Creator:: Medina, Rebecca A.
Abstract:: This thesis describes the chemical investigation of marine cyanobacteria collected in Madagascar and Panama with an emphasis on the isolation and structure elucidation of medicinally relevant secondary metabolites. A collection of the marine cyanobacterium Lyngbya majuscula from the Radames Islands, Madagascar yielded two new cyclic depsipeptides, radamamides A and B,...

Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

Creator:: Parsotan, Tyler M.
Abstract:: Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

Foam-Core Meniscus Coating and Diffusion Bonding for Energy Applications

Creator:: Saranam, Venkata Rajesh
Abstract:: In the second chapter, a foam-core meniscus coating process was developed for retrofitting 100 nm-scale sol-gel anti-reflective coatings onto in-field solar panels through the deposition, evaporation, and curing of wet films.Advantages of this technique include the means to control fluid flow relative to substrate motion and the ability to conform...

Heavy fermion effective mass in the superconducting vortex state

Creator:: Townsend, Emily A.
Abstract:: The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...

Integrated Spatial and Temporal Stochastic Model in Radiation Biology : Design, Implementation, and Application

Creator:: Liu, Ruirui
Abstract:: Mathematical modeling plays a pivotal role in understanding the mechanism of radiation-induced cellular effects, and also in quantifying the radiation risk to the cell. However, there are still compelling challenges facing the conventional modeling in radiobiology, such as lacking a generalized theory structure of quantifying target effect and non-target effect...

Effect of cosputtered catalyst on growth and alignment of carbon nanotubes by plasma enhanced chemical vapor deposition

Creator:: Gunderson, Eric P.
Abstract:: The effect of cosputtered catalyst on growth and alignment of carbon nanotubes (CNTs) grown by plasma enhanced chemical vapor deposition (PECVD) was investigated. Aligned CNTs were observed using a cosputtered catalytic metal deposited directly on boro-aluminosilicate glass. Catalytic metal alloys were sputtered directly onto the substrate using magnetron sputtering. Deposition...

Impact of Process Optimization and Composition on Thin Film BNKT Microstructure, Ferroelectric and Piezoelectric Response

Creator:: Grove, Kyle M.
Abstract:: Recent changes in legislation restricting lead content in waste streams produced during electronics manufacturing have inspired a strong push to develop alternative lead-free materials systems for piezoelectric applications. One lead-free piezoelectric material system, (100-X)Bi₀.₅Na₀.₅TiO₃-XBi₀.₅K₀.₅TiO₃ (BNKT), has shown promising properties in bulk research, however, difficulties have arisen in the development of...

Engineering an Ex-Vivo System to Study Transport Phenomena in the Human Intervertebral Disc

Creator:: Shalash, Ward
Abstract:: Back pain is the leading cause of disability worldwide, entailing a significant socioeconomic impact. A primary source of back pain can be attributed to intervertebral disc (IVD) degeneration allowing nerve ingrowth, facet joint arthritis, disc bulging, and osteophyte formations that press on nearby nerve roots or the spinal cord. While...

Biological characterization of coibamide A, a marine natural product from a Panamanian cyanobacterium

Creator:: Hau, Andrew M.
Abstract:: Coibamide A is a methyl-stabilized cyclic depsipeptide with a lariat side chain that was isolated from a marine cyanobacterium as part of an International Cooperative Biodiversity Groups program based in Panama. Previous testing of this potent and selective growth-inhibitory agent in the National Cancer Institute (NCI) in vitro 60 human...
