Production of C4-C10 Hydrocarbons from CO₂, H₂O, CO, H₂ and CH₄ Utilizing DC Glow Discharges, Catalytic Rapid Temperature Pulsing in Micro-Scale Reactors.

Creator:: Mohamed, Omar M.
Abstract:: This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...

Mycorrhizal Fungi on the Sagebrush Steppe: Benefits for Restoring Keystone Rangeland Plant Species

Creator:: Prado-Tarango, David E.
Abstract:: Arbuscular mycorrhizal fungi (AMF) are plant symbionts that associate with the vast majority of terrestrial plants species. The AMF colonizes the plant roots by penetrating the root cortical cells, where the fungi exchanges mineral nutrients with the host plant for photosynthates. This association exists as a complex system in which...

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...

Morphological variability and seed dormancy of Amelanchier (Rosaceae) grown in Oaxaca, Mexico

Creator:: Cruz-Cruz, Efrain
Abstract:: The purpose of this research was to determine whether hybridization between Amelanchier denticulata. (H.B.K.) Koch and Amelanchier nervosa (Decaisne) StandL occurs in Oaxaca, Mexico, and to evaluate components of yield and germination characteristics and seed dormancy of Amelanchier denticulata. Amelanchier nervosa and Amelanchier denticulata samples and morphological characters were used...

In silico screening of nanoporous materials for gas sensing and separation

Creator:: Gantzler, Nickolas
Abstract:: The utility of high-throughput, computational screening has become an invaluable asset to the field of materials science. In the hierarchy of computational methods, the most accurate methods are often the most computationally expensive. However, as both the efficiency and fidelity of numerical techniques advance, high-quality screening of large materials datasets...

Natural products studies of the marine cyanobacteria Lyngbya semiplena and Lyngbya majuscula

Creator:: Han, Bingnan
Abstract:: This thesis details my investigations of marine cyanobacterial natural products that resulted in the discovery of eighteen new secondary metabolites. Isolation and characterization of these unique molecules were carried out using different chromatographic techniques and by careful analyses of 1D and 2D NMR data, respectively. Preliminary bioassays of the crude...
