Soil respiration flux in response to soil temperature, moisture, and pH

Creator:: Murphy, Bailey
Abstract:: Soil respiration has been identified as one of the largest natural sources of CO₂ to the global carbon cycle. Small alterations in the magnitude of soil respiration can have potentially large effects on concentrations of atmospheric CO₂ , making the rate at which respiration occurs of great scientific interest (Martin...

Relative heat sensitivities and the potential for soil solarization to remediate nursery beds infested with Phytophthora spp.

Creator:: Weidman, Clara Suzanne
Abstract:: Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...

Organic Semiconductors : Incorporating Xylindein into (Opto)Electronic Devices

Creator:: Rath, Jeremy J.
Abstract:: This research investigates the electronic properties of a fungi-derived pigment, xylindein as a novel sustainable material for organic electronics. Xylindein molecules were characterized in solution and in film. Absorption spectra and (photo)luminescence spectra were taken at various excitation wavelengths. Xylindein’s molecular properties were computed with the Gaussian 09 software suite....

The rate-based paper detection of vanillin and m-cresol using a colorimetric tyrosinase mediated chitosan-quinone reaction

Creator:: Hinson, Dylan
Abstract:: Monitoring the concentration of phenolic compounds is important for environmental regulation, health diagnostics, and bioenergy fermentation. Vanillin is a phenol compound used as a food flavoring that can cause allergies and inhibits biofuel production. The phenol m-cresol is a toxic compound that is regulated in the environment and in human...

Colorimetric analysis of creatinine in whole blood and urine in a novel paper/polycaprolactone microfluidic device

Creator:: Pommerenck, Joel, Heist, Christopher A., and Remcho, Vincent T.
Abstract:: A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...

Electrical Transport Measurements Show Intrinsic Doping and Hysteresis in Graphene p-n Junction Devices

Creator:: Plunkett, Garrett R.
Abstract:: Understanding the electrical transport properties of graphene provides a basis for determining its future as a potential semiconducting device that can be used for the next generation of transistors and photodetectors. Graphene p-n junctions can also function as field effect transistors, and thus are a logical starting point for I-V...

Practical Mechanically Interlocked Molecules: A Model of Gas Adsorption in Metal OrganicFrameworks Harboring Rotaxane Molecular Shuttles

Creator:: Carney, Jonathan
Abstract:: Metal organic frameworks(MOFs) are a class of crystalline materials utilized in gas storage, chemicalsensing, and other engineering applications. Recently chemists have begun synthesizing MOFs withmoving parts in order to further these applications. A wide array of dynamic MOFs have been created andtheorized. Among them is the interlocking of a ring...

Development of Micro-Electrode Array Sensors for Electrochemical Detection of Dissolved Oxygen

Creator:: Hansen, Hanna M.
Abstract:: Microelectrode array (MEA) dissolved-oxygen (DO) sensors were built and electrochemically tested in a solution of potassium ferricyanide. MEAs are becoming more popular as DO sensors because of their small size and capacity for simultaneous measurements with multiple recording sites. The ability to measure DO with multiple recording sites is useful...

Variable Temperature Transport Measurements and Conduction Mechanisms of Crystalline and Amorphous Titanium Dioxide Thin Films

Creator:: Patterson, Acacia M.
Abstract:: The electrical properties of amorphous and crystalline titanium dioxide polymorphs are reported. Titanium dioxide is a widely used transparent semiconductor and it is a useful oxide model. Using variable temperature transport measurements of thin films, it was possible to establish the activation energy barrier for conduction. This was accomplished using...
