A (3-Aminopropyl)triethoxysilane (APTES) and Glutaraldehyde Functionalized Cellulose Surface for Immunoassays

Creator:: Harley, William
Abstract:: The detection of biomolecules is critical for clinical diagnostics but requires specialty labor and high cost. The use of microfluidic paper-based analytical devices (µPADs) for bioassays is simpler and cheaper but has low sensitivity. Improved immobilization of antibodies onto cellulose is demonstrated through surface functionalization with APTES and glutaraldehyde. The...

Controlling the Co-Precipitation of Colloidal PbSe Quantum Dots and Their Device Performance in a Diode Architecture

Creator:: McCrea, Tyler D.
Abstract:: In this work, colloidal PbSe quantum dots (QDs) are shown to be synthesized in a controlled manner by changing the growth time and reaction temperature in a microwave synthesis method. It is explained why quantum dots make such a unique material to create electronic devices and the specific benefits that...

Fundamental Investigations of Electrocatalysis: Mechanistic Implications of Catalyst Electronic Structure

Creator:: Carvalho, O. Quinn
Abstract:: Heterogeneous catalysis modulates the rate and selectivity of reaction processes by stabilizing a series of intermediate states on solid surfaces, facilitating the production of many commodity chemicals modern society relies upon. Conventional, thermal catalytic processes—conducted at elevated temperatures and pressures—source thermal, mechanical, and chemical potential energy from carbon-hydrogen bonds— combustion...

Field-use electrochemical sensors for detection of carbamazepine in saliva and water

Creator:: Minzlaff, Jade
Abstract:: The anticonvulsant drug carbamazepine (CBZ) is a commonly prescribed drug that is used to treat patients with neurological disorders including epilepsy and bi-polar disorder. CBZ has a narrow range of efficacy: Below the therapeutic dose, seizures and other conditions are not controlled, and above the recommended window, patients experience side...

A Graph Grammar Representation of Metal-Organic Frameworks for Computational Synthesis and Exploration

Creator:: Geringer, Mark K.
Abstract:: In this work, metal-organic frameworks (MOFs) are computationally represented, generated, and evaluated. The organic linker molecules are represented as graphs and use graph grammars where the atoms are represented by nodes and the bonds are represented by arcs. The grammar rules that dictate the graph generation process work on the...

Electrochemical assessment of binder free Co_xNi_1-xS_y electrocatalysts supported on carbon nanofibers for oxygen evolution reaction in alkaline media

Creator:: Namiiro, Sauda Kiggundu
Abstract:: Water splitting is a green method being researched to produce green hydrogen in order to combat greenhouse gases emitted by the most popular energy source; fossil fuels. Water splitting involves two half reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Of these two, OER is the bottleneck water...

An Investigation into the Production of Longer Hydrocarbons, Synthesis Gas, and Ammonia via a Nonthermal Plasma Microreactor

Creator:: Reddick, Ian T.
Abstract:: Nonthermal electrical plasmas can allow energy intensive reactions to occur without the use of high operating temperatures or pressures. This is because the collisions of electrons accelerated through an electric field with molecules is the cause of reactions as opposed to thermal collisions between molecules. In this study, the production...

Surface Characterization of Engineered Biomaterials

Creator:: Faase, Ryan A.
Abstract:: The work presented in this dissertation highlights the various techniques available to characterize the increasingly complex surfaces of engineered biomaterials. The methods used range from the simple measurement of a contact angle with a smartphone to a complex synchrotron technique like near edge x-ray absorption fine structure (NEXAFS) spectroscopy to...

Environmental Transformations of Nanoparticles in Natural Water Systems using a Hydrophobic and Hydrophilic Dye Assay

Creator:: Turnquist, Macklin C.
Abstract:: Nanoparticles (NPs) are generally defined as particles <100 nanometers (nm) in size in one dimension. Despite increasing industrial usage of TiO2 NPs in sunscreens, cosmetics, and water remediation little is known of their environmental behavior. The primary goal of this research was to develop a rapid method for determining the...

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...
