Quantum dot plasmon coupling : Fundamental study and applications

Creator:: Kannegulla, Akash
Abstract:: The dissertation focuses on the engineering of light-matter interaction using plasmonic nanoparticles and metamaterials to achieve enhanced luminescence and based on which to improve the performance of biosensing and light-emitting technologies. We designed and fabricated a spectrum of nanostructures to exhibit particular dispersion relations capable of controlling the spontaneous emission...

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...

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...

Functional materials for advanced energy and electronic devices

Creator:: Flynn, Brendan T.
Abstract:: Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...

Catalytic chemical vapor deposition synthesis of carbon nanotubes from methane on SiO supported Fe and Fe−Ni catalysts

Creator:: Nakagawa, Ayako
Abstract:: Influences of operating conditions on the production of carbon nanotubes (CNTs) were studied using Fe and Fe-Ni bimetallic catalysts supported on silicon monoxide (SiO). The catalysts were prepared in three steps: (1) impregnation of SiO powders with ferric nitride or combinations of ferric and nickel nitrides, (2) oxidation of nitrides...
Resource Type:: Masters Thesis

Developing rapid in vivo assays to investigate structure response relationships

Creator:: Truong, Lisa
Abstract:: Incorporation of nanoparticles (NPs) into consumer products is on the rise and human exposure to NPs is unavoidable. Currently, there is insufficient data to assess the safety of nanoparticles. I conducted a series of five studies using the zebrafish model to determine which NP components (i.e., core material or surface...

Study of Garnet Type Electrolyte Li₇La₃Zr₂O₁₂ Structure and Electrochemical Performance

Creator:: Wang, Yan
Abstract:: Cubic phase Li₇La₃Zr₂O₁₂ (LLZO) is a promising solid electrolyte for all solid-state lithium-ion battery, due to its reasonable ionic conductivity, stable against metallic Li, wide chemical window, and thermal and chemical stability. The main aim of this thesis is to investigate the influences of different synthesis methods on the structure...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

Electrical Conductivity in Mixed-Species Biofilms for Enhancing Energy Generation in Anaerobic Microbial Systems

Creator:: Li, Cheng
Abstract:: Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...

Transition Metal Oxides for Aqueous Electrochemical Energy Storage

Creator:: Jiang, Heng
Abstract:: In the 21st century, environmental deterioration is now an indisputable fact. Reliable and economically viable electricity systems based on renewable sources are urgently needed to replace the environmentally detrimental fossil fuels. The feasibility of incorporating renewable-but-intermittent solar and wind energy heavily depends on the development of cost-effective and safe technologies,...
