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,...

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...

Organic-solvent resistant ultrafiltration and nanofiltration membrane modules for separation and purification of nanoparticles

Creator:: Kim, Taehyeong
Abstract:: The intriguing size- and shape dependent properties of nanoparticles have garnered recent attention in many science and engineering areas. When the particle size is in the nanometer size range, the material exhibits very different properties such as surface plasmon resonance (of gold nanoparticles) and superparamagnetism (of iron oxide nanoparticles). The...

Magnetic particles for selective extraction of trace analytes in microfluidic devices

Creator:: Tennico, Yolanda H.
Abstract:: The development of micro total analysis systems (µTAS), also called “lab-on-a-chip”, or microfluidic analysis systems, is presented in this dissertation. Various research areas, covering subjects from magnetic particles synthesis to novel microchip fabrication techniques, are explored to develop a lab-on-a-chip system capable of performing magnetic bead-based bioassays. These devices are...

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...

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...

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...
