Theoretical Study of Solvent Effects in Heterogeneous Catalysis using Density Functional Theory

Creator:: Chukwu, Kingsley C.
Abstract:: Heterogeneous catalytic reactions in solvents are important for chemical processes like direct methanol fuels, biomass conversion to biofuels and electrochemical reduction of CO2 to fuels. Numerous experimental studies have shown that co-adsorbates and solvents affect the rate and selectivity of heterogeneous catalytic reaction, therefore fundamental understanding of how co-adsorbates and...

Hydrogen Interaction with Platinum and Palladium Surfaces

Creator:: Boechler, Amanda N.
Abstract:: Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...

Solvation Effects of Water on Dimethyl Ether Interactions with a Platinum Catalyst

Creator:: Chang, Alvin
Abstract:: Our society today is heavily dependent on fossil fuels such as coal and oil. However, growing environmental concerns and future fossil fuel supplies have led to interests in alternative fuels. Dimethyl Ether (DME) is an inexpensive, clean-burning, non-toxic, and potentially renewable fuel, making it a suitable choice as an alternative...

Oxidation Energies of Chromium and Tungsten Substituted Ni (111) Surfaces

Creator:: Roth, Anika
Abstract:: The corrosion and heat resistance properties of nickel alloys are hallmarks of their importance in infrastructure and industrial catalysis processes, but these properties are highly dependent on the chemical composition of the alloy surface. Density functional theory was used for analysis of surface oxidation of four combinations of chromium and...

Optimizing Cancer Drug Treatment Models Using Process Dynamics

Creator:: Jones, Alexander R.
Abstract:: Cancer is currently the second leading cause of death in the United States and the sixth leading cause of death worldwide. Due to cancer’s variability in type, location, growth rates, and patient physiology, treatment models are based off of previous experimental and clinical work. This variability, however, can lead to...

Solvent and Dispersion Effects on the Hydrodeoxygenation of Acetic Acid on a Pd(111) Model Surface

Creator:: Rebarchik, Michael A.
Abstract:: Increased dependence on fossil fuels and concerns of anthropogenic climate change have led to increased interest in alternative energy sources. Liquid fuels derived from renewable raw materials have gained attention in recent years due to their similarity to petroleum-based fuels. Biofuels derived through hydrodeoxygenation have been found to be one...

Surface composition age analysis of photo-oxidized polystyrene thin films by X-ray photoelectron spectroscopy

Creator:: Silva, Nicholas A.
Abstract:: Polystyrene thin film surfaces are commonly used to study the interactions of macromolecules, such as proteins, with surfaces. Polystyrene films oxidized in UV light become more hydrophilic, however these surfaces have a limited shelf life because they are reduced over time. Experiments were performed to determine the effect of radiation...

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...

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...

Density Functional Theory Study of the Reaction Mechanism of Chloride-induced Depassivation of α-Fe2O3

Creator:: Pang, Qin
Abstract:: Carbon steel, which contains mostly iron, has been widely used as reinforcement in reinforced concrete. In the alkaline environment in reinforced concrete, a thin iron oxide film, called the passive film, forms on the surface of the steel, which protects the surface from active corrosion. The exact atomic structure of...
