In the present study, we report the synthesis of thermally stable mesoporous gallium oxide and novel gallium-niobium mixed oxides employing Evaporation Induced Self-Assembly (EISA), Self-Assembly Hydrothermal-Assisted (SAHA) and Self-Assembly...
A novel catalyst with hydro-desulfurization and hydrogenation capabilities was tested with the aim of producing ultra-low sulfur and aromatics diesel oil. The catalytically active phase is nickel in a reduced valence state on a carrier made of zinc...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...

Meat is a major component of the diet of an American. However, humans do not consume one-third to one-half of each animal raised for their needs. The leftover materials are subjected to processing in the meat rendering industry. The rendering...
Dielectrophoresis (DEP) is an electrokinetic force capable of attracting or repelling neutrally charged particles due to a non-uniform electric field [1, 2]. Positive dielectrophoresis attracts particles in the region of the highest electric field...
This thesis is an examination of the viability of a low pH hydrogen peroxide scrubbing process for removing H 2 S acid gas present in typical biogas streams generated from dairy farm anaerobic digesters. Biogas ranges in composition based on the...
This thesis describes 1) the kinetics of vapor phase place exchange reactions on films of gold monolayer protected clusters (Au MPCs) to alter the functionality of the Au MPCs, 2) applications of the reaction for altering chemiresistive sensing...
This dissertation describes research focused on the synthesis, polymerization and
applications of cationic aminooxy lipids. An efficient and convenient method was
developed to stabilize liposomes using 'click chemistry'. The 'click...
The motivation to determine a viable alternative to petroleum based energy has risen in recent years due to increased greenhouse gas emissions, environmental pollution, and the fear of exhausting oil and natural gas reserves. Biodiesel derived from...
Cancer is the second-most leading cause of death in the United States, with 1.66 million new cases expected to be diagnosed and over 580,000 Americans expected to die of cancer in 2013 alone. (American Cancer Society 2013) Current treatments result...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
Archaeologists use soil analysis to detect chemicals, like phosphate, to indicate areas of anthropogenic activity. Phosphate detection is a multi-step process, which makes standard techniques time consuming. Kinetic studies decreased the analysis...
Understanding the nucleation and early stage growth of crystals from the vapor phase is important for realizing large-area single-crystal quality films, controlled synthesis of nanocrystals, and the possible discovery of new phases of materials....
Single Walled Carbon Nanotubes (SWNTs), Double Walled Carbon nanotubes (DWNTs) and C60@SWNT (peapods) are three of well-ordered all-carbon nanostructures. Peapods are SWNTs filled with C60 fullerene peas. At high temperatues, C60 molecules coalesce...
The Technical Advisory Group (TAG) of the Innovative Treatment Remediation Demonstration Program (ITRD) made technology recommendations after reviewing thirty in situ remediation technologies for implementation at the Paducah Gaseous Diffusion...
We have measured the temperature-dependent thermal conductivity, K(T) of single walled carbon nanotubes from 300 K to 8 K by 3w methods. K(T) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement...
The fundamental importance of a definite knowledge of the quantity of each amino acid yielded by the several food proteins justifies the expenditure of much effort in studying the analytical methods in order that these may be improved or their...
Contamination can be very difficult to remove from water. Once this water seeps into the ground, the difficulty grows exponentially. The Paducah Gaseous Diffusion Plant, located in Paducah, Kentucky, has contaminated the groundwater. The...
Protective coatings; Microelectromechanical systems
PARYLENE (poly-para-xylylene) is mostly used as a conformal protective polymer pin-hole free coating material to uniformly protect any component configuration on diverse substrates. This thesis describes in detail how the unique properties of...
Enzymatic hydrolysis is the most common method of producing fermentable sugars from lignocellulosic biomass. Limitations to this step include the high cost of enzymes, and the time required to process the biomass. To increase the throughput and...
