Concentration Effects on Enhanced Particle Removal with Viscoelastic Fluids

Creator:: Cashen, Ryan K.
Abstract:: Highly elastic solutions have been shown to increase contaminant removal from silicon wafers, indicating the possibility for reduced reliance upon hazardous chemicals and expensive technologies during the fabrication of semiconductor devices. The onset of this enhanced removal is explored using rinsing and siphoning experimentswith polymer fluids of high molecular weights...

Microwave-Assisted Synthesis and Chemical Modulation of MOF-74(Ni)

Creator:: Aldossary, Abdulrahman N.
Abstract:: Metal-organic frameworks (MOFs) are crystalline porous material distinguished for high free empty volume and pore tunability. MOF-74(Ni) was previously shown to be effective in adsorbing carbon dioxide, methane, and hydrogen. Microwave-assisted synthesis of MOF-74(Ni) was shown to lower reaction time from days to hours. In this thesis, experimental conditions of...

Assessment of roles for the Rho-specific guanine nucleotide dissociation inhibitor (RhoGDI) Ly-GDI in platelet function

Creator:: Thierheimer, Marisa
Abstract:: Platelets undergo morphological changes essential to hemostasis upon activation at sites of vascular injury. The Rho GTPases Rac1, Cdc42, and RhoA drive these changes. Rho guanine nucleotide dissociation inhibitors (RhoGDIs) bind to the Rho GTPases to block the GDP from dissociating from the Rho GTPases, as well as anchoring the...

The Stability, Toxicity, and Reactivity of Zero Valent Iron Nanoparticles

Creator:: Bulovsky, Hannah G.
Abstract:: Zero valent iron nanoparticles effectively remediate groundwater contaminants due to their catalytic properties and enhanced surface area. However, these properties contribute to particle agglomeration, decreasing their effectiveness. In this study, we examined the effect of two stabilizing agents (gum arabic (GA) and sodium carboxymethyl cellulose (CMC)) on particle stability, toxicity,...

Investigation of Magnesium Dioxybenzenedicarboxylate (Mg-DOBDC) Thin-film Deposition onto Modified Glass Substrates

Creator:: Haning, Evan J.
Abstract:: Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...

Functionalization of Poly(3-hexylthiophene-2,5-diyl) for Nanoelectromechanical Devices

Creator:: McConnell, Chelsea A.
Abstract:: Innovative nanoelectromechanical switches (NEMS) have the prospects to reduce device actuation voltages as compared to traditional semiconductor devices. Current research on NEMS seeks to avoid irreversible adhesion at the nanoscopic level, which results in device failure. Minimizing leakage currents and increasing device longevity are additional goals of this approach. The...

Thermodynamics of Laser-Assisted Solution Combustion Synthesis of Yttrium Oxide

Creator:: Dhas, Jeffrey A.
Abstract:: To assess the conversion and embedment of yttrium nitrate to yttrium oxide using selective laser melting, a thermodynamic approach for laser power and scan speed predictions on surface temperature, recoil pressure, and resulting track morphology window are employed. Inkjet printing is used to deposit the liquid film of yttrium nitrate...

UV-assisted lipoic acid ligand exchange of copper indium disulfide-zinc sulfide core-shell quantum dots

Creator:: Porth, Lane D.
Abstract:: Water-soluble quantum dots obtained through ligand exchange are widely applicable for biological imaging and marking, LEDs, and photovoltaics. Lipoic acid (LA) was reduced to dihydrolipoic acid (DHLA) using 365-nm soft UV light in a process known as photoligation, and ligand exchange with dodecanethiol-capped CuInS₂-ZnS core-shell quantum dots occurred. The reaction...

Surface Structure Sensitivity to Fuel Adsorption on Pt(111) and Pt(100) and Carbon-Oxygen Bond Breakage at the Anode of a Direct Dimethyl Ether Fuel Cell

Creator:: Schneider-Coppolino, Merissa
Abstract:: As conventional energy sources begin to deplete, the need for alternative, renewable energy becomes more necessary. Dimethyl ether (DME) fuel cells are a promising energy source that could fulfill these demands. Compared to well-known fuel cell fuels, such as methanol, DME has a low toxicity and high energy density. Experimental...

Plasma enhanced growth of carbon nanotubes

Creator:: Ford, Neil I.
Abstract:: Carbon nanotubes (CNTs) are grown using plasma enhanced chemical vapor deposition (PECVD). A modified radio frequency (RF) parallel-plate plasma etching system serves as the growth reactor. The effects of process parameters, including temperature, pressure, and C2H2:NH3 ratio, are studied. CNTs are grown on glass substrates with Al underlayers and Ni...
